- Q:Does the check valve damage affect the flow rate?
- Ball check valve will not affect the flow, such as the clip type check valve once damaged, it will affect the flow.
- Q:What is the function of the check valve on the air compressor?
- Check valve is also called one-way valve, air will not go in only, can protect the air compressor host, if the air compressor main machine does not stop, you can not check valveIf it starts frequently, it must be loadedCheck valve bad consequences: motor overload, burn the host top off
- Q:What is the material of H41W-16's check valve?
- Both cast iron and stainless steel are possible
- Q:How many kinds of structure are there in the check valve?
- 2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;
- Q:How much is the check valve for the concrete pump?
- 31 concrete pump price ranging from 15W to 60W, different configurations have different prices, which one do you want?
- Q:What kind of check valve is used in the sewage pump of sewage treatment plant?
- 3. to prevent hydraulic impact on the check valve sealing surface damage protection measures, check valve settings, to prevent the backflow of material, pump impeller to avoid the impact of the role of liquid. But as for the check valve itself, improper setting will cause a sudden impact of the disc on the valve seat by the water hammer, and damage the check valve sealing surface. Therefore, several protective measures should be taken. 1, for the pump outlet set >80mm swing check valve, horizontal installation should be adopted to weaken the valve seat back and the impact. 2, for the pump outlet check valve >=150mm diameter of the pipeline, should be placed before and after the bypass valve, to prevent the pressure before the valve rises too high, the check valve sealing surface damage. 3, the pump discharge pipeline starting and ending pressure is higher, the pipeline is not allowed to set the bypass, you can take the following measures. Set up safety valve instead of bypass valve. The action is similar to that of the bypass valve. It is located near the check valve outlet. When the water hammer causes the pressure to rise, a part of the water can be released to prevent the damage caused by the pressure rising. An air or inert gas buffer tank can be set. It is located near the check valve outlet, and when the water hammer is produced, the pressurized gas is compressed through the buffer tank to alleviate the pressure rise caused by the water hammer.
- Q:How do I use the triangle and check valves?
- The function of the check valve is to prevent the backflow of medium, generally used in water pumps
- Q:Check valve h42h-dn80 what does that mean?
- According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve4 = connection: flange2 = structure form: vertical lifting typeH = sealing surface material: Cr13 stainless steelDN80== nominal diameter: 80mm
- Q:I also calculate each pump check valve and gate valve?
- The pump adapter itself does not include the gate valve and the check valve! Only when a group called pump adapter will include adapter, gate valve and check valve!If the pump adapter in the list of units for the group then all included and work content in clear note on the contents.If you do it alone, write out no items!
- Q:How to prevent the backflow valve of medium
- The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.
