Q:What are the differences between different check valves applications?
The application performance of the acoustic check valve only allows the medium to flow in one direction, and prevents 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. Not suitable for medium containing solid particles and viscosity. The design of the check valve takes full account of the requirements of the use of the environment, and uses the inclined plate structure to achieve no vibration, no noise, stable operation, and ensure the quiet environment of the hotel and the residential environment, and has the effect of energy saving.
Q:Swing check valve can prevent any sewer defection
The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a 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!
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 to control the common flue return and smoke return?
In the hood outlet to install a reasonable design, shut tight, open the hood in place, can be easily wind blown open, will not be open to the flue suction, and the blade contact area is very small, and a sealing ring, not to hinder the blade opening exhaust flue check valve closed Miller beauty you can eliminate the smoke intrusion and poor smoke.
Q:What is the function of the check valve?
The function of the check valve is to prevent the medium from flowing back! Check valves, which are commonly known as check valves! Backflow of medium will cause the reverse of pump impeller, which may lead to the burnout of pump! Pumps used in industry are expensive nowadays! Ha-ha! The check valve just protects the pump and piping!
Q:How many kinds of check valves should be used?
Check valve applies to the occasionThe purpose of the utility model is to prevent the backflow of the medium, and the half of the utility model is provided with a check valve at the outlet of the pump. In addition, a check valve shall be installed at the outlet of the compressor. In a word, check valves shall be installed on the equipment, installations or pipelines to prevent the flow of the medium.Generally in the nominal diameter of 50mm horizontal pipelines are selected vertical lift check valve. Straight through lift check valves can be installed on both horizontal and vertical lines. At the end of the valve is generally installed in the vertical pipe of the pump inlet, and the bottom-up flow of media.Swing check valve can be made at a high working pressure, PN up to 42Mpa, and DN can also do great, maximum up to 2000mm or more. Depending on the material of the housing and the seal, any working medium and any operating temperature range can be applied.
Q:The principle of the 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.
Q:Butterfly check valve should be equipped with special flange for butterfly valve
No, with a special appearance Jansen point flange butterfly valve. It can barely be installed without special flanges
Q:Method for mounting back check valve of pump
