- 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:Can the check valves fit two in one tube? One up, the other down
- Launching, then you'd like to have a Sheung Shui at the front of the Sheung Shui
- Q:Check valves - check valves - what's the difference between one-way valves?
- 3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar
- Q:Should the kitchen check be mounted on the wall or on the hood?
- It should be mounted on the wall. If you have more questions, click ID.
- Q:What is the difference between the check valve and the check valve?
- 1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
- Q:My hood inside outside blow valve pops ringing
- Please take the pipe at the hood of the range hood for 15 cm or more, and then blow the wind. Note that the installation of fixed, do not affect the valve sag.
- Q:I also calculate each pump check valve and gate valve?
- Are you talking about budget calculations? According to the bill of quantities valuation standard, the project code 030701019 has included what you said, without additional calculation.
- Q:How to install the water pipe check valve?
- If the pipe in the installation position is vertical, you can choose the swing type and pipe type!If the installation position of the pipe is horizontal, you can choose the lifting type!Lift check valve opens and stops at the fastest speed!The swing check valve has the least resistance!
- Q:What happens when the check valve is broken?
- Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent media backflow valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve.The check valve belongs to an automatic valve whose main function is to prevent the reverse of the pump and drive motor and the leakage of the container medium.If the check valve is broken, there will be media backflow, pump and drive motor reversal, as well as the leakage of container media
- Q:What is the function of the small check valve on the deep well pump?
- This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
