- 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: What is the function of the stop valve and check valve installed on the water supply pipe?
- The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q: Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?
- Greater than DN600, you can use HBH747H hydraulic butterfly butterfly valve closed, less than DN600 with HD43X slow butterfly butterfly check valveThis is the usual selection, not necessary, there is no provision, but this choice is not wrong. There are, of course, other types of check valves.The hydraulic check valve is hydraulic, and the Baidu library contains instructions for the HB series and the HD series hydraulic check valves
- Q: The air pipe is equipped with a check valve
- [air pipe with check valve] wind pipe with check valve, is to prevent changes in the direction of the wind generated negative pressure, the phenomenon of air intrusion.[duct] is a pipe system for air delivery and distribution.[check valve] refers to the flow itself depends on the media itself and automatically open and close the valve, 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 backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.
- Q: What type of check valve is the h61y-40 check valve?
- I. lift check valves: check valves that slide along the vertical centerline of the valve body. The lift check valves can only be installed on the horizontal pipe. The disc can be used in the high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve thrust open by the media, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect. Straight through lift type check valve medium channel with import and export channel direction perpendicular to the valve seat; vertical lift check valve, the media import and export channel in the direction of the same direction with the valve seat, the flow resistance is smaller than the straight through.
- Q: I would like to ask you the following questions: Recently, the newly purchased three Lin electric water heater, installed in the upper layer of the five bathrooms, a faucet, that is left to wring out hot water, to the right to wring out cold water, mixed type.1 when there is no safety valve, the hot and cold flow is normal, but the check valve is dripping.2 manufacturers said that the high level to safety relief valve, dripping water and this also concerned, it took more than 100 safety valve, on the cold water pipe, but since then, hot water flow and its small, cold water normal, the check valve is still dripping.3 excuse me, check valve, check valve, safety valve is not a thing? Is it just a different name?4 is the relief valve the same as the relief valve?Now it's really a tough one. How do you solve the problem of small drop of water and hot water flow? The manufacturer said the pressure, but I very cold water washed!Thanks for the answer!
- Check valve and check valve is to prevent backflow of water, the valve is used for pressure relief, when the water heater pressure is too high, the pressure through the pressure relief valve and pressure relief valve on the other: for water, the quality is not good, the main problems for the water pressure is too low to cause, and check valve and pressure relief valve will further reduce the pressure, you can try to check off a try, I think the check valve is useless. If not, just add a booster pump to the cold water inlet.
- Q: What's the difference between the cut-off, check, check, and stop valves three? Better picture,
- Stop check valve: when the handwheel is rotated so that the valve stem rises, the disc does not rise together, but only the valve clack is released.
- Q: How do I use the triangle and check valves?
- The triangle valve is used for connecting taps and water equipment. Check valves are used to prevent backflow of water.
- Q: What is the reason that the valve is not used for a period of time?Anonymous browsing | 314 times
- 7, when installing check valve, should pay special attention to medium flow direction, should make medium normal flow direction and the direction of the arrow on the valve body is consistent, otherwise it will cut off the normal flow of media. Valve should be installed at the bottom of the pump suction pipe.The general formula 8, lift check valve should be installed in horizontal pipe, vertical lift check valve and bottom valve is usually installed in a vertical pipe on the road, and the bottom-up flow of media.9, the check valve closes, will produce water hammer in pipeline pressure, will lead to serious damage to the valve and piping or equipment, especially for the big pipe or high pressure pipeline, it should pay attention to those who use check valve.
- 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!
