Why has the problem of stress reduction not been solved for a long time?

Because there is a need, because it can't be done.

If the pressure reducing valve is damaged, it will be dripping all the time, or the water heater is in a heated state, and the pressure reducing valve of the water heater discharges water in order to reduce the pressure on the inner tank of the water heater, which is a normal phenomenon.

There is also the possibility of damage to the pressure relief valve of the water heater, when the water heater is not heated, the inner tank of the water heater is not so much pressure at all, the pressure relief valve will not automatically relieve pressure under normal conditions, if the pressure relief valve of the water heater appears to relieve pressure and drainage, it is likely to be caused by the damage of the pressure relief valve, which requires the electric water heater manufacturer to come to repair and replace the pressure relief valve.

The one you are talking about is not a pressure reducing valve, it is a pressure relief valve, and it also runs when it is not heated, indicating that your local water pressure is too high, exceeding the starting pressure of the pressure relief valve, so even if it is not heated, it is also relieved, the solution is to install a pressure reducing valve in the inlet pipe of the household or buy a pressure relief valve with a higher starting pressure, but it is recommended to install a pressure reducing valve, because it can solve the problem and save water, and the starting pressure of the pressure relief valve is not known to have an impact on the water heater.

Let the after-sales service help you overhaul and use qualified regular accessories.

You're talking about a check valve, it's time to replace it if it's broken.

The best way is to exercise and make yourself sweaty, but if you are a person who has not exercised for a long time, please pay attention to the amount of exercise, don't make yourself tired, and pay attention to replenishing and keeping warm in time after exercise. To reduce stress is to normalize your metabolism, which is generally smooth.

Drink tea to lower blood pressure. Jasmine tea has the effect of calming the mind and relieving stress.

Go outdoors and do some exercise and see what's out there that doesn't concern you.

In fact, the most fundamental thing to reduce stress is to release pressure, or exercise, or vent, or find someone to talk to, or put things aside and think from a different angle. Drink a glass of milk in the evening, listen to a little light **, and soak your feet.

Naturally, it's relaxing!

Turn big things into small goals and solve them gradually. Don't be yourself.

Boys have more outdoor sports, and girls go shopping.

Relax more, listen to **, soothe your emotions.

The flow rate of the pressure reducing valve has nothing to do with whether the fire is prosperous or not, and whether the fire is prosperous or not is determined by the outlet pressure value of the pressure reducing valve; The national standard stipulates that the export pressure is generally 2800 pascals; Under this pressure, the flame often does not reach the level of stir-frying, but the safety performance is good;

The size of the flow rate determines the number of stoves that can be used at the same time under this one pressure reducing valve; The number of stoves that can be used at the same time is large, but the size of the valve fire is only related to the outlet pressure, that is, whether one or more stoves are used at the same time, the fire power is the same.

Nowadays, many miscellaneous or copycat pressure reducing valves often have outlet pressures higher than the national standard, so that the flame can be very strong, but this does not meet the national standard, and the risk factor is high.

Principle of action: The pressure reducing valve is to reduce the water pressure by the local resistance of the flow channel in the valve, and the range of water pressure drop is automatically adjusted by the membrane connecting the valve disc or the inlet and outlet water pressure difference on both sides of the piston. The principle of fixed-ratio pressure reduction is controlled by the water pressure ratio of the floating piston in the valve body, and the pressure reduction ratio at the inlet and outlet ends is inversely proportional to the area ratio of the piston at the inlet and outlet sides.

This type of pressure reducing valve works smoothly and without vibration; There is no spring in the valve body, so there is no worry about spring rust and metal fatigue failure; The sealing performance is good and there is no leakage, so it reduces both dynamic pressure (when water flows) and static pressure (when the flow rate is 0); In particular, the pressure is reduced without affecting the water flow.

Working principle: The pressure reducing valve is to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve, so that the pressure behind the valve is kept within a certain range, and spray cooling water in the valve body or behind the valve to reduce the temperature of the medium, this valve is called pressure and desuperheating valve. The pressure reducing valve is fast and easy to optimize the automatic selection.

The valve is characterized by keeping the outlet pressure and temperature values within a certain range when the inlet pressure is constantly changing.

Advantages: Although there is a large head loss of water flow through the pressure reducing valve, it is still energy-saving in general because it reduces water waste and makes the system flow distribution reasonable, and improves the system layout and working conditions. When the medium is steam, it is advisable to choose a pilot piston pressure reducing valve or a pilot bellows pressure reducing valve. For ease of operation, adjustment and maintenance, pressure reducing valves should generally be installed on horizontal pipes.

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjusting it, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can change, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve is kept constant within a certain error range.

The noise generated by the pressure reducing valve is a malfunction. It shows that the pressure reducing valve is unstable, the pressure oscillation is large, and sometimes the noise is large.

According to the provisions of the relevant standards, the pressure oscillation of the J type pressure reducing valve is O LMPA, and the pressure oscillation of the J type is O 3MPa, and the pressure oscillation is large and unstable when the standard is exceeded.

J-type and JF type pressure reducing valves are pilot-operated, and the pilot valve is common with the relief valve, so the cause and elimination method of large pressure oscillation can be carried out with reference to the relevant part of the relief valve.

When the pressure reducing valve is used in excess of the rated flow, the main valve oscillation phenomenon often occurs, which makes the pressure reducing valve unstable, and the pressure of the oil outlet appears "boosting, decreasing, increasing and lowering again", so it is necessary to choose a pressure reducing valve suitable for the model and specifications.

The back pressure of the oil drain port L is large, and the pressure oscillation and unstable pressure will also be generated, and the oil drain pipe should be returned to the oil separately.

The deformation or stiffness of the spring is not good (poor heat treatment), resulting in large pressure fluctuations, and the qualified spring can be replaced.

You haven't used it, it's only in the process of use, and now your valve is closed, and there is no gas passing through the pressure reducing valve of the pressure reducing valve. Of course there is no pressure.

The pointer shows the pressure inside the cylinder, not the amount of gas!

1. You are a pressure reducing valve with an explosion-proof device [press down on the middle cylinder, and the airflow will pass].

2. In winter, the temperature is low, the pressure in the cylinder is small, and the pointer may be in the middle position!

It's definitely not right to exhaust all the time, although it's new, but it's not necessarily good. It should be that the hole screw in the center of the valve membrane is not tightened, causing air leakage.

The screws in the center hole of the rubber diaphragm are installed.

There is a small hole in the top of your pressure reducing valve, when the lower part of the valve body is ventilated with gas, the gas pressure overcomes the pressure of the constant pressure spring to make the valve port diaphragm bulge, open the channel, and the gas will be released.

This is normal.

And is it possible to make sure that there is no problem with the pipeline, blockage, or whatever, otherwise it is impossible to ignite and there is gas in the pipeline.

There are several reasons for this kind of situation, 1. The lid of the pressure cooker is not tightly covered; 2. The pressure reducing valve on the lid of the pot is not closed and is in the exhaust position; 3. The sealing rubber ring on the lid of the pressure cooker has failed; 4. The contents of the pressure cooker exceed the normal capacity of the pressure cooker. Check 1 and be able to solve it.

It's useless in itself, and of course it's not good. Please say the symptoms, I'll tell you**method, reset yourself** and you'll be fine immediately.
