Installation form and precautions of hydraulic water level control valve Fault maintenance introduct

There are many valve products, they play a different role, today for you as an example is a control valve products, through intelligent and automated design, it can be operated according to the level of the water level, so as to play the effect of control, then you may wish to learn about the steps and precautions about the installation form of this type of hydraulic water level control valve, in addition to the common causes of failure and analysis and treatment methods, Friends who are interested or want to learn and understand through this believe that they can get satisfactory information and results.

1. What are hydraulic water level control valves and remote control float valves?

Hydraulic water level control valves and float level controllers are two types of liquid level control devices that are often used together.

Hydraulic water level control valve: It is a kind of equipment that uses the pressure in the inlet and outlet pipes to drive the valve disc to act.

Float level controller: It is a kind of control equipment that uses a float (float) with a density less than the liquid to float on the liquid surface and move up and down with the liquid level to drive (generate) a control signal or directly drive a valve.

Hydraulic level control valves and float level controllers are two types of equipment used for level control that are often used together.

Second, what happens when the hydraulic water level control valve does not come out of water

There are several reasons for the loss of control of the hydraulic water level control valve: 1. The water pressure becomes low; 2. The piston is jammed; 3. The sundries are stuck and the valve core cannot be moved; 4. The small float cannot be closed or not fixed; 5. The valve core may be blocked by dirt and cannot pass water; 6. The water-stopping rubber pad is damaged.

3. Installation form and precautions of hydraulic water level control valve?

Hydraulic water level control valve installation form: the valve is vertically fixed on the water inlet pipe, and then the control pipe, globe valve and float valve are connected and screwed on the valve.

Precautions: 1) The diameter of the water inlet pipe should be greater than or equal to the nominal diameter of the valve, and the water outlet should be lower than the float valve.

2) The float valve should be installed more than one meter away from the water pipe; Drill a small hole in the outlet pipe in the tank above the water line to prevent direct air backwater.

3) When in use, the globe valve should be fully open, and more than two valves should be installed in the same pool, and the same level should be maintained. Because the main valve closes after the float valve closes for about 30 50 seconds, the water tank should have enough free volume to prevent overflow.

4) In order to prevent impurities and sand particles from entering the valve and causing work failure, a filter should be installed in front of the valve.

5) If it is installed in the underground water pool, the alarm device should be installed in the underground pump room.

As a kind of liquid level control equipment, the hydraulic water level control valve can not only play a controlling effect, but also because it can cooperate with the height of the liquid level of the water tank water tower, according to the parameters of the later setting, and carry out intelligent operation by itself, so its existence also reduces the trouble of manual monitoring, greatly reduces the investment of the early cost, and its application is relatively wide now, which can be seen in the production process of some large-scale production equipment, and in other fields. It can also provide many advantages that cannot be replaced by accessories, so the above is the relevant information. If you are interested, you can start for reference.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Hydraulic water level control valve is a kind of hydraulic control valve used to control the water level of the leakage, and its requirements for water pressure mainly include the following aspects: 1Maximum permissible water pressure:

Hydraulic water level control valves usually have a certain range of water pressure, and they should be designed and manufactured to ensure that problems such as leakage and rupture will not occur when working within this range. Therefore, when selecting a hydraulic water level control valve, you should understand the maximum water pressure of the valve to ensure that it can work properly within the required water pressure range. 2.

Minimum water pressure requirements: The hydraulic water level control valve needs a certain water pressure to open and close normally, so in actual use, it is necessary to ensure that the water pressure of the water source is not lower than the minimum requirements of the valve, otherwise it may cause the valve to fail to work normally. 3.

Stable water pressure: Hydraulic water level control valve needs stable water pressure to maintain smooth control of water level, if the water pressure fluctuates greatly, it may lead to unstable water level control, which will affect the working effect of the valve. To sum up, the hydraulic water level control valve has strict requirements for water pressure, which needs to be fully considered in design and manufacturing, and at the same time, it is necessary to ensure that the water pressure meets the requirements of the valve when using it, so as to ensure its normal operation and water level control effect.

What happens when the hydraulic water level control cavity wheel rubber valve is installed only after the water does not come out 1, and the water pressure becomes lower; 2. The piston is jammed; 3. The sundries are stuck and the valve core cannot be moved; 4. The small float cannot be closed or fixed without a side; 5. The valve core may be blocked by dirt and cannot pass water; 6. The installation form of the hydraulic water level control valve is damaged by the water-stopping rubber pad: fix the valve vertically on the water inlet pipe, and then connect the control pipe, the globe valve and the float valve and tighten it on the valve.

Hydraulic water level control valveThis is something that ordinary people rarely come into contact with in life, and some people may have never heard of it, although everyone does not know much about it, but its function and role for people can not be ignored. Therefore, the following is to give you the popular science of the hydraulic water level control valve, and by the way, I will also teach you some Xunyunxin installation knowledge about it.

1. Select the type of hydraulic valve.

Because there are many models of hydraulic water level control valves, and each model can support different acres of crop rotation, so before installing the hydraulic control valve, it is necessary to correctly select the hydraulic water level control valve with matching specifications and models according to the working pressure requirements, medium temperature, and physical and chemical properties of the control valve.

In addition, because the hydraulic water level control valve has relatively high requirements for water hardness, if the karst landform like Guizhou, the bicarbonate cover contained in the water is easy to scale under the action of temperature and hydraulics, then it is recommended to choose a larger hydraulic control valve and appropriately increase the diameter of the control pipe.

2. Install hydraulic valves reasonably.

Once you have selected the appropriate type of hydraulic water level control valve for your needs, you can then install it. In the process of installation, of course, it is also necessary to install reasonably according to the characteristics of the product, and there are some precautions that need to be paid more attention.

The flange connection needs to be selected to match the model, specification and pressure of the hydraulic valve.

The diameter of the inlet pipe needs to be the nominal diameter of the valve, and the outlet should be lower than the float valve.

The float in the hydraulic valve should be installed more than one meter away from the water pipe mouth, for example, the manhole of the pool is gold-plated, which is conducive to maintenance.

The two ends of the valve piston rod of the hydraulic valve need to be tightened nuts and anti-retreat measures should be taken, so as to prevent the valve core structure from loosening due to hydraulic power in the future use process.

The outlet of the outlet pipe in the water tank needs to be quietly set with an anti-siphon hole, or the outlet should be set slightly higher than the control water level, so as to prevent the siphon from flowing back.

The water outlet of the control valve should be equipped with an energy dissipation cylinder to prevent noise and water level fluctuations.

The tank volume needs to be sufficient, because the main valve closes after the float valve closes for about 30 to 50 seconds, and if the tank does not have enough free space, there will be overflow.

In order to prevent magazine and sand particles from entering the control valve and causing malfunction, it is recommended to install a filter in front of the valve.

If the hydraulic water level control valve is installed in the basement pool, then an alarm device needs to be installed in the basement.
