Whether the fire pump is equipped with a slow-closing check valve or a slow-closing silencer check valve.

Under normal circumstances, the fire pump uses a slow-closing silencer check valve. The slow-closing silencer check valve has a good sound reduction effect, which can effectively reduce the noise of the fire pump and improve the service life of the fire pump.

Summary. Hello, a slow-closing check valve is a flow control device installed in a liquid line to restrict the flow of fluid from the pressurized side to the low-pressure side. The slow-closing silencer check valve is a check valve with a muffler, its main function is to prevent the liquid in the pipeline from mixing with each other, but also to reduce the noise caused by leakage.

The above is mine, I hope it can help you, I wish you a happy life.

Hello, check valves can be divided into slow-closing check valves and slow-closing silly check valves, and fire pumps generally use slow-closing check valves. The above is mine, I hope it can help you, I wish you a happy life.

Summary. Dear, I am happy to answer your questions, 1. The function of the slow-closing check valve is to prevent the reverse flow of the medium, and the function of the slow-closing silencer check valve is to reduce the noise of the circulating medium. 2. The slow-closing check valve usually adopts a spherical or circular element, while the slow-closing silencer check valve usually adopts a special check valve element, which has a silencing function.

3. The slow-closing check valve has the characteristics of high temperature resistance, corrosion resistance, wear resistance and high compressive strength, while the slow-closing silencer check valve has the function of silencing, which can reduce the noise and fluctuation of the medium in the process of medium flow. 4.

Whether the fire pump is equipped with a slow-closing check valve or a slow-closing silencer check valve.

Dear, fire pumps are usually fitted with slow-closing check valves. Slow-closing check valve is a valve that controls the direction of water flow, which can maintain the direction of water flow and prevent the water in the fire pump from slipping and reverse flowing, thereby preventing the damage of the fire pump. The working principle of the slow-closing check valve is that when the fluid passes through the core gate of the valve, the valve will gradually reduce the flow rate of the mountain pass, and finally the valve will be closed, so as to achieve the check effect.

Sometimes it is also equipped with a slow-closing silencer check valve, which has the same function as a slow-closing check valve, but has a silencing function to reduce the noise of the fire pump.

Abstract:The silencer check valve is a kind of check valve that can reduce or eliminate the noise generated by the water flow through the valve, and the reason why it has the effect of silencing is that the internal water flow path of the silencer check valve adopts a streamlined design, the head loss is very small, and the valve disc can be quickly closed to avoid water hammer and prevent the sound of huge water hammer, so as to have the effect of silencing. In addition to the silencer check valve, there is also a silent check valve, comparatively speaking, the principle and function of the two are similar, but the silence effect of the silent check valve is better, and the sound can be directly shielded.

Let's take a look at the silencer check valve. 1. How is the silencer check valve silenced.

The check valve can prevent the internal medium from backflowing, but it has a disadvantage, that is, it will produce relatively large noise, in some special occasions, lower noise is required, so there is a valve of the silencer check valve, so what is the silence principle of the silencer check valve?

Ordinary check valves will have noise, mainly because the water pressure and flow are affected in the process of water flow, and there is a certain amount of energy loss, which produces water hammer and noise; The internal water flow path of the silencing check valve adopts a streamlined design, and the head loss is very small, which is about 1 2-1 3 compared with the ordinary check valveAt the same time, because the disc of the silencing check valve is spring-loaded, the disc closing stroke is very short when the pump is stopped, and it can be closed quickly to avoid water hammer and prevent the sound of huge water hammer, so as to achieve the effect of silencing.

2. What is the difference between a silencing check valve and a silent check valve?

Silencer check valve and silent check valve are both commonly used in hydraulic control valves in a type of hydraulic valve, installed at the outlet of the water pump, to avoid huge water hammer, to prevent backflow, the effect is similar, and can reduce noise when in use, but these two kinds of check valves also have some differences.

The difference between the silencer check valve and the silent check valve is mainly in the silencing ability, the silencer check valve only eliminates the noise and reduces the noise; The silent check valve can directly shield and mute the sound when in use.

The reason why the silent check valve has a stronger silencing ability than the silencing check valve is mainly because of the difference in principle, the silent check valve, which adopts the contour design in line with hydraulics, obtains the best streamlined waterway next to the filial piety, and the design of the internal attachment to the fluid can ensure small pressure loss; The silent check valve is installed at the outlet of the water pump, which can be quickly closed before the water flows backwards, avoiding water hammer, water hammer and destructive impact, so as to achieve a silent effect.

The silencing effect of the silencer check valve and the silent check valve is different, and the use is mainly based on the needs of customers and the use of occasions to choose.

Fill the capsule of the isolation device with water first; Open half of the micro control valve first; The adjustment of the piston adjusting screw will make the adjustment such as the judge pull rod pull out 1 3 of the full length, and the piston can stretch out 2 3 and fix the adjusting screw nut; Close the blowdown valve and open the check valve.

2 small valves play the role of switches, if the small valve is closed, the valve does not have a slow closing effect. One controls in, one controls out.
