Wafer Check Valve

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。: Self suction pump reverse water valve is a check 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. 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. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis).The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the 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:Are the gate valves and check valves of the same type?: Check valve is a check valve function, is to prevent the media back, it is by the valve on the pin shaft and the rotary switch to play the role of the valve with different things, when it is opened by medium pressure automatic opening, closing time depending on the medium and back type the self gravity valve closed, it is a kind of automatic gate valve function, does not require an external force is applied to it, it is a demand for the direction.

Q:What's the difference between a stop valve and a check valve? Is it a valve?: The cut-off valve is a common valves, mainly used to connect or disconnect the line of medium, generally not for regulating flows.globe valves for a wide range of pressure and temperature, but are generally used for medium and small diameter pipes. The cut-off valve is closed parts (valve) moving along the centerline of the valve seat valve. The stop valve is mainly used for cutting in the pipeline.

Q:There is a check valve at the inlet of Haier electric water heater to prevent water from flowing back. Because there are many hot water used in the house, should the hot water be fitted with check valve?Can the hot water outlet be fitted with check valves? The hot water pipe is too long for hot water to flow back into the heater... Is it possible to install two check valves to affect the normal use of the heater?: Hot water outlet should be equipped with check valve, for the following reasons:Closed type electric water heater in the outlet by one or more water control valves and water storage type electric water heater, and work in tap water under pressure. The utility model has the advantages of flexible installation position, high water outlet pressure, small heat loss, etc.. But because its inner liner is working under pressure, it needs thicker material and high manufacturing process. The outlet of open type electric water heater is opened and water is controlled by a valve on the water inlet pipe.

Q:What's the difference between a throttle valve and a check valve? Are they the same?: The principle is very simple, just like upstairs said, like a revolving door, this is the swing test. There are lifting type, it is unknown.And "throttling" is to reduce the pressure of the fluid. In the pipeline, the fluid through the throttle valve, through the hand wheel or other transmission way to adjust the size of the internal channel, so that the flow of fluid flow down, to save traffic flow.

Q:We are high-rise buildings, with the smart recharge meters, before always someone to reflect the water used soon, 27 tons of water in only a month has gone. Later I heard that the water meter in front of a check valve on it, but when the five tons of water after the use of nothing, and nothing. Why does that happen? Does the check valve stop the water meter from idling?There is a special case, thirty storey building, booster pump has a pressure in the debugging of the fifteenth layer of what, every time on the twentieth floor of the owners reflect his home water intermittent, sometimes when a shower suddenly no water, we always to reflect the property many times, we are the plumber debugging a few times, or not. Later said that can not be adjusted, and then the tune will burst, and this is how it happened? How can I solve this problem? Why didn't the owners of the thirty and fifteen floors reflect the shortage of water pressure? But the owners of the more than 20 floors are so unlucky?: 2.3 installation methods and installation quality2.3.1 since the water meter is now out of the door, most of the units are all concentrated in one box and installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.2.3.2 installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.

Q:The check valve for the printer doesn't have any air in it, but it doesn't come out. It still doesn't work: From your personal statement, analysis of leakage, box of ink cartridges, ink the check valve back looked at the appearance of normal needle, injecting ink into ink box to see, I wish you good luckIn addition, I have not used check valve, the friend that has seen, personal speculation that there is a switch, should be misleading you

Q:Installation of stainless steel tank outlet must be equipped with check valve?: Outlet?If the delivery is not waterIf the pump is pumped up, it should be loaded

Q:Fire hood fire check valve okay?: 1, the new product role2, the role of soot exhauster smoke exhaust fumes sent to the public flue gas pipeline, with the smoke fumes from the flue gas flow into the room to ensure that the quality of the domestic air environment, home health3, fire valve temperature control device and block check plate up to prevent the flame through public exhaust pipe series.4, the specific selection to check, see products through fire products, testing, assessment, no certificate, and price

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;

Yue,located in Ducun Industrial Park, Linhu Town, Wuzhong District, Suzhou, mainly produces valves. Our company is equipped with one scale automatic static coating line, two assembly testing lines, many sets of semi-automatic assembly testing equipment as well as processing equipment such as 5m,3m and 2m vertical lathes, 4m and 2m milling machines and boring machines.
