Why should the water heater inlet pipe be equipped with a safety valve? What is the purpose of the s

Introduction: When using water heaters in daily life, we must pay more attention, because there will be many potential safety hazards when using water heaters.

So people have to pay more attention. <>

The safety valve is also the pressure relief valve, the water heater safety valve has two functions, one is to avoid the internal pressure of the water heater is too large, resulting in the water heater bursting, because the water heater is a closed container, when heating, if the water pressure is relatively high, the pressure will rise to higher, beyond the normal equipment pressure range, the water heater liner will be broken or **, the other is the check valve.

The function is that the water entering the water heater from the inlet pipe is allowed to enter but not out, so as to avoid entering the hot water of the water heater, because the water is stopped or the water pressure is insufficient, resulting in backflow to the water inlet pipe. <>

The shape of the safety valve is a three-way pipe, according to the general installation situation, that is, there is a nozzle up and down in the vertical direction, and the upper pipe.

The mouth is connected to the water pipe of tap water, the upper pipe mouth is connected to the inner tank of the water heater, there is a one-way valve that can only be opened upwards in the museum, the water in the water pipeline can be pushed open and the door enters the inner tank, when the water pressure of the inner tank is larger, the valve is closed under the joint action of water and spring, the water can not flow back to the water pipeline, when the pressure of the water in the inner tank exceeds the set value, the water will flow out of the drain. <>

When installing the socket, it is best to install the socket higher than the water heater to prevent the water from splashing into the socket when taking a bath, causing an electric shock accident.

, these substances will corrode its magnesium rods. Once the magnesium rod is corroded or the heating pipe is corroded and perforated, there is also a risk of leakage. Hence the electric water heater.

In the process of maintenance, check the potential safety hazards of the water heater to prevent problems, and be sure to replace the magnesium rod of the water heater regularly.

The installation of the safety valve is to prevent the backflow of hot water, which helps to help the discharge of pressure inside the water heater and the cleaning of scale inside the water heater; The function of the safety valve is to ensure the normal operation of the water heater and prevent the water heater from appearing and endangering the safety of people's lives and property.

This prevents the electrical appliance from being affected by pressure, and also avoids crackage, ensuring that it can be used. It can play a role in guaranteeing and safety, which is conducive to avoiding the rupture of water pipes, relieving water pressure, and ensuring the speed of water flow.

Because this can ensure safety, in case of danger, it can be better controlled, and at the same time, the pressure inside the water heater can be adjusted through this safety valve, which can be avoided.

Because the hot and cold water can only be successfully adjusted after the safety valve is installed, the function is to control the cold water and hot water in the water heater.

You can find the corresponding **, log in to your personal information, and finally find the payment page, and go in to complete the payment.

For the water heater inlet pipe to install the safety valve, its main purpose is the following aspects: check backflow, safe pressure relief, drainage cleaning.

In our daily life, we will use a variety of water heaters, water heaters are a kind of device that uses a variety of physical principles to heat a certain amount of cold water and turn it into hot water, so as to meet our daily water needs. Its main components are the casing, exhaust device, air control and water control device, and heat exchanger, etc. As an indispensable part of the installation of water heaters, the safety valve is a kind of safety device to prevent the danger of eliminating the high water pressure of the water heater liner, so as to install a safety device, which is mainly composed of three parts: valve seat, valve core and loading mechanism.

Safe pressure relief. When the water heater is heated, the water temperature of the inner tank will gradually increase, because the inner tank is a closed space, with the increase of air temperature, the internal pressure will gradually increase, when the pressure of the inner tank is higher than the pressure of the pressure relief spring of the safety valve, the water will be discharged from the pressure relief valve of the safety valve, and the pressure of the inner tank will be reduced through such a pressure relief drainage valve.

Reverse reflux. For the safety valve of the electric water heater, the check valve included in it can effectively prevent the backflow of the water pressure caused by the high water pressure caused by the high inner tank of the water heater. Drain cleaning.

Because the safety valve of the water heater is suitable for electric water heaters, for the safety valve of the multi-functional water injection electric water heater, the valve body is divided into a water inlet cavity, a water outlet cavity and a safety cavity by a three-way system, and our safety cavity has a drainage hole, which can make the water in the electric water heater under too high pressure, play a role in drainage, and also play a role in cleaning the water heater.

In short, for water heaters, we must install safety valves and install them in accordance with the operating instructions, so as not to bring hidden dangers to our safety due to improper installation.

The installation of a safety valve can control the inlet pipe of the water heater and ensure the normal operation of the water heater. The purpose is to prevent the water heater from heating dry, which will lead to **.

Because in this way, the amount of effluent and incoming water can be controlled, safety issues can be well controlled, waste of resources can be avoided, and safe operation standards can be met.

This is done to ensure safety, to prevent problems in the bath, and to avoid danger to life.

The water heater safety valve is a multi-functional storage electric water heater safety relief valve, which is suitable for electric water heaters and air energy water heaters, and has the functions of check valve and pressure relief valve, which can prevent the backflow of water into the electric water heater and discharge excess pressure when the pressure of the inner tank of the electric water heater is high, so as to ensure the life of the inner tank and avoid the occurrence of bile burst accidents.

Water heater safety valve, valve body tee, divided into water inlet cavity, water outlet cavity and safety cavity, the safety cavity has a drainage hole, in the water outlet cavity placed check valve core, external adjustment spring, limited by adjusting the limiting sheet, in the safety cavity placed elastic pad, safety valve core and drainage rod, safety pressure adjustment spring, adjusting cover through the drainage rod screwed into the safety cavity, there is a protective cover plate outside, the end of the drainage rod is connected with a drainage ear, the drainage ear is buckled with a protective buckle, and the protective buckle is fixed on the drainage hole seat with a drainage pipe joint.

It has the functions of check backflow, safe pressure relief, drainage cleaning, etc., and is easy to adjust. The safety valve should be installed vertically and at the vapor interface of the vessel or pipeline.

Electric water heater. The safety valve has three functions:

1. Pressure relief, the pressure of the water storage bucket will rise when the water is heated, if the thermostat fails, the pressure will be higher and higher, which will cause the water storage bucket to burst and the danger will occur, and the safety valve will automatically open and relieve the pressure when the pressure reaches a certain value to ensure safety.

2. Check valve.

Function, the safety valve is still a check valve, the check valve will be opened by the water pressure of the inlet pipe when the water is inlet, and the hot water will flow into the water supply pipeline due to the increase in pressure in the barrel when heating, and the check valve will prevent the hot water from flowing back.

3. Drainage, because the water heater barrel is usually full of water, the water outlet is in the upper part of the barrel, and the water can not be discharged when the drain is opened.

The safety valve must be installed on the water inlet, and the pressure value and use method of the safety valve of different brands and models of water heaters may be different, depending on the instructions for use, so as to avoid the danger of improper use.

The small screws are used to fix the handle and do not need to be disassembled, but do not tighten it too tightly when using it, so as to ensure that the handle has a certain movement clearance.

The function of the safety valve:

1. The role of pressure relief. When the electric water heater is plugged in, when it is working, if the water pressure of the part is relatively large, then the pressure relief valve plays a role, which can eliminate the excess pressure in time, ensure the safety of the water heater and prolong its service life.

2. The effect of preventing water backflow. When the water heater is working, it is necessary to ensure that there is enough water stored in it, in case there is no water in the electricity, there will be dry boiling, which is very dangerous. The installation of a pressure relief valve can effectively prevent the occurrence of such accidents and avoid the backflow of water.

The water heater safety valve plays a protective role, which should prevent excessive pressure.

Water heater pressure relief valve installation steps

1. Before installing the pressure relief valve on the protected equipment or before installation, it must be re-adjusted at the installation site to ensure that the setting pressure value of the pressure relief valve meets the requirements.

2. Within the range of spring working pressure level indicated on the nameplate, the opening pressure can be adjusted by changing the spring compression by rotating the adjustment screw.

3. Before rotating the adjustment screw, the inlet pressure of the valve should be reduced to less than 90% of the opening pressure to prevent the valve disc from being driven to rotate when the adjusting screw is rotated, resulting in damage to the sealing surface.

4. In order to ensure the accuracy of the opening pressure value, the opening pressure is generally reduced when the working temperature rises. Therefore, when adjusted at room temperature and used at high temperature, the setting pressure value at room temperature should be slightly higher than the required opening pressure value.

6. When the conventional pressure relief valve is used to fix the additional back pressure, when the opening pressure is adjusted after the inspection (the back pressure is atmospheric pressure at this time), its setting value should be the required opening pressure value minus the additional back pressure value.

Before using the pressure relief valve, it needs to be turned on, and as long as the water pressure inside the tank is too high, the pressure relief function can be realized. If the pressure of the inner tank of the water heater is exceeded, the pressure relief valve will relieve the pressure by itself and let the water flow out along the valve port to ensure the balance of the internal pressure and make it safer to use.

The water heater safety valve should be installed at the cold water inlet of the water heater.

The safety valve of the water heater has the function of overpressure protection and a one-way valve, so there is an installation direction, and the direction of the shear head on the valve body is the direction of water flow.

Usually the safe pressure value of the water heater is the pressure value that is marked on some valve bodies.

When the internal pressure of the water heater increases, such as the thermostat is broken, the water heater has been heated, the steam increases, the pressure will rise a lot, and it is easy to cause danger, at this time, the safety valve will be relieved to the safe value.

The function of the check valve is that when the water is stopped, the water inside the water heater will not be pumped back into the tap water pipe by other water equipment, resulting in no water heating in the water heater and burning out the heating pipe.

The function of the electric water heater safety valve is that when the electric water heater is running, if the pressure suddenly increases or the pressure of the water tank is too large, the relief valve can release a certain pressure to ensure that the water tank of the water heater is not damaged, and it is also to prevent the water tank from appearing. Installed at the inlet of the electric water heater, when the internal current is heated, the pressure is stabilized, the excess pressure is effectively discharged, and the use process is safer.

But when the water heater is heated, the safety valve is prone to dripping, but the most important thing is to see if the pressure is within the product range. In addition, in the event of a sudden water cut-off, the safety valve will turn on the reverse flow mode to avoid drying the appliance. The pressure relief valve must be connected to the water inlet of the water heater, when installing, it is best to wrap several circles of ribbon on the nut of the water inlet, which can prevent slackness in the later stage, the pressure relief valve is a three-way shape, according to the general situation of the installation, each vertical fluctuation has a nozzle, the nozzle is facing the water pipe, the pipe is facing the water tank, there is a one-way valve in the pipe that can only be opened upwards, and the water in the water pipe can push the valve into the water tank.

When the water pressure in the tank is high, the valve closes and the water can no longer flow back into the water pipe. Make sure the liner is not damaged, but does not drip every time it is heated. If the pressure is normal, the safety law will not drip water.

When the water heater is heated or filled with water and the air is discharged, the pressure on the inner tank of the water heater will be increased.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

This way, there is no risk of water leakage. It can also prevent the effects of stress. There will be no cracking. That's why there is such a safety protection device.

Because the installation of safety valves can ensure that the water pipe does not have the risk of rupture, and can reduce the pressure of the water pipe, can ensure the better use of the water pipe.

Avoid excessive pressure in the water heater to prevent it from causing it, which can play a safe role in avoiding the backflow of water into the water heater and backflow to the water pipe.

Summary. My water heater at home is equipped with a safety valve, and after using it for a while, I found that the water temperature is relatively stable and there is no overheating, so I think the safety valve is safe. The safety of the water heater safety valve depends on the quality of installation and use, if the installation quality is good and the use is normal, the water is safe.
