Usage/Applications Of Swing Check Valve

-Various modes of the pipeline, prevent the medium backflow

- Products Design Features: Flanged & Butt-welding ends swing check valves are used in pipes under pressures between PN 1.6-16.0MPa,Class 150-900Lb,working temperatures between -29-570 °C, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power generation to prevent the backward flux of the media.

- Operation: Handle operation, electric.

Swing Check Valve

Q: Check valve H41T-16. What are the numbers and letters in it?: H stands for check valve, 4 stands for flange 1, and represents form 16 for pressure. This is cast iron lift check valve

Q: Does the check valve differ in front of the water meter and press it behind the water meter?: According to the specification, check valve (check valve) should be installed behind the watch. If it is placed in front of the meter, it will cause the meter to be inaccurate and damage the meter parts.

Q: How many kinds of check valves should be used?: Ball check valve because the sealing part is covered with rubber ball, therefore, good sealing performance, reliable operation, anti water hammer performance; the seals can be a single ball, they can make more balls, so you can make large caliber. But its seal is wrapped in rubber hollow sphere, does not apply to high pressure pipeline, only applies to the middle and low pressure pipeline.Because the shell material of spherical check valve can be made of stainless steel, sealed hollow sphere parts can be coated PTFE plastics, can also be applied in the pipeline so general corrosive medium.The check valve in the working temperature between -101~150 DEG C, the nominal pressure is less than 4.0Mpa, nominal in the range of 200~1200mm

Q: Which type of check valve should be selected for vertical pipes?: The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited

Q: With no negative pressure water supply, the pump is equipped with a check valve, the construction ring network also needs to install check valve?: With no negative pressure water supply, the pump is equipped with a check valve, the construction ring network also needs to install a check valve, or else the water pump may enter the ring network.

Q: Only one is a soft seal and one is hard sealed: Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H

Q: How many kinds of structure are there in the check valve?: 3 butterfly check valve structure similar to butterfly valve, its structure is simple, flow resistance is small, water hammer pressure is smaller;4, diaphragm type check valve has a variety of forms, are used as the opening and closing the diaphragm, due to its good waterproof performance, simple structure, low cost, rapid development in recent years, but the use of diaphragm valve temperature and pressure by the diaphragm material limited;

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: Swing check valve can prevent any sewer defection: Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. This kind of valve should be installed horizontally in the pipeline.

Q: Is it better to have explicit rules in the relevant specifications? Thank you, ah, ah, urgent.: Article 8.5 of the code for fire protection design of high-rise civil buildings provides as follows:8.5.3 one of the following circumstances shall be equipped with fire dampers for the ventilation and air conditioning systems:8.5.3.1 pipe through fire compartment.
