- Q:For home use, self suction pumps are installed outside the well and pumped into the water tank.Please check with the self-priming pump function (check valve, water valve)? If not, is not installed in the pipeline connecting wells and pumps? Thank you。
- Both, but there are good or bad points, good seal, with a spring, the general is a piece of rubber plus a piece of iron, plus a check valve is feasible
- Q:The difference between check valve and check valve
- 1, one-way valve: is a typical seat valve, one-way valve Check, Valve, also known as check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow. There are two one-way valve one-way and right angle type. Straight through one-way valves are threaded and installed on the pipe line. The right angle one-way valve has threaded connections, plate connection and flange connection in three forms. Liquid control check valve, also known as blocking valve or pressure valve, which is the same as one-way valve, used to prevent reverse flow of oil. But in the hydraulic circuit needs the oil flow reverse flow, but also can use the control oil pressure, opens the one-way valve, causes the oil flow to be possible to flow in two directions. The hydraulic control check valve adopts a conical valve core, so the sealing performance is good. When the closed oil circuit is required, the valve can be used as the one-way locking of the oil circuit to maintain the pressure. Liquid control check valves control the leakage of oil, there are two types of internal and external leakage. In the oil flow reverse outlet, no back pressure in the oil pipeline can be used to vent type; otherwise, need to leak type, in order to reduce the control oil pressure2, check valve is only one kind of valve, it can be said that one-way valve is a kind of check valve,
- Q:Detailed distinction between backflow preventer and check valve
- The backflow preventer consists of two separated check valves and a drain valve. Due to the local head loss of the check valve, the pressure in the middle cavity is always lower than the pressure at the inlet. This pressure difference causes the drain valve to be closed and the pipe is in normal water supply. In abnormal pressure (i.e., the outlet pressure is higher than that of the middle cavity), even if the two check valve can not reverse sealing, safety relief valve can automatically open the reverse water emptying, and the formation of air separation, ensure the health and safety of water upstream.Check valves are plain check valves, only one side seal. Backflow preventer is more expensive than ordinary check valve. Double protection and heavy protection!
- Q:Are the common check valves stand upright or horizontally installed?
- 3. install the check valve, pay attention to medium flow direction and check valve arrow direction should be consistent.
- Q:How to install the kitchen flue check valve?
- 1, vertical transport, the flue should take protective measures, and must be two lifting.2. Locate the center line of the flue position. In the reserved hole, draw down four vertical central lines from the roof, and draw 2 orthogonal central lines on the floor plane.3, the flue to the scene, the first flue hanging to the roof, surrounded by the center line of pop in the flue, and the flue of the reserved hole slowly down the electric hoist, from top to bottom layer installed flue in place, the center line correction. The center line of the flue and the center line of the reserved hole should be less than 1cm, the deviation of the centerline of the upper and lower flue is not greater than 1cm, and each flue must be guaranteed vertically and vertically.4, the installation of flue should each layer as bearing, bearing steel 2 root diameter over 14mm?.5. After the flue is installed, install the check valve hole at each flueFire type flue check valveFirst, stir the cement with a special glue, coat the edges of the check valve, and then install it at the opening of the check valve.6, the construction should be reserved at all levels of the hole, covered with a cover plate, to ensure safety in construction, to prevent construction waste fall into the flue.7, the flue is thin-walled components, in handling and installation should be gently handle, not to impact, not in the pipeline to pile other heavy objects and walking.8, the roof flue should be in the roof insulation layer, fire layer before construction. 9, the use of gas water heater exhaust system is strictly prohibited.
- Q:What's the difference between check valves and non-return valves?
- Other check valves (check valves), such as blowdown check valves,Civil air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
- 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.
- Q:Why is the water ring vacuum pump equipped with check valves?
- The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
- Q:Can the check valve be used on the steam pipe?
- The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
- Q:What is the function of the stop valve and check valve installed on the water supply pipe?
- globe valves for a wide range of pressure and temperature, but are generally used for medium and small diameter pipes. The home tap water valve should be designed as most of the valve.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.
