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:What is the difference between the H44H check valve and the H41 check valve?: The large check valve shall be independently supported so as not to be affected by the pressure caused by the piping system2, attention should be paid to the direction of the flow of the medium should be in accordance with the direction of the body marked arrow3. Vertical lift check valves shall be mounted on vertical pipes4.

Q:Tap water tank with vertical and horizontal check valve.: Look at your pipe installation position, if it is vertical, of course, the vertical check valve is good, if it is horizontal, of course, choose a horizontal check valve.The function of the check valve is to ensure the flow of the fluid in one direction. The moving parts are usually pressed against the seat to form a seal. Small pressure must be applied to moving parts to open the valve. Once opened, fluid power is generated to allow the valve to open or increase opening. Before the valve closes, fluid flow must stop. Fluid power generated by fluid flow prevents all valves from closing. The spring can be used or not to control the opening and to close it. Some check valves rely solely on gravity to provide closing force. Valves that rely on gravity must be installed according to the manufacturer's instructions. If horizontal pipes are laid, the slope of a short distance local pipe must be changed.The swing check valve is powered by gravity. When the valve is opened, the force required to control the valve opening is increased. If the balance between disc weight and fluid dynamic force is incorrect, the valve will not be fully opened. Increasing flow speed may cause unexpected corrosion or erosion damage, so gravity driven valves must be used to meet operating conditions.When the valve is fully opened, the disc or piston stroke must be limited by the stopper. Fully open valve, but not limited, the valve is easy to vibration. Vibration may cause hinge pins or pistons to wear rapidly. Valves using springs may suffer from early spring faults (caused by fatigue). Vibration may be caused by vortices or disturbances. When the fluid has some viscosity, the fluid damping can control the vibration. Valves with springs may be fitted with different rigid springs. If the full stroke stops, including extrusion, to prevent backlash after rapid opening, this can be an effective vibration damper.

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?: The cold water pipe already has a check valve. In fact, it also returns the hot water pipe. It also returns the hot water with cold water. It has already met your demand well. To the hot water pipe and then put a completely make an unnecessary move! And it's impossible to get hot water back again. May you enjoy the joy and happiness of hot water!

Q:What is the difference between check and check valves? Check and check valves?: 2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.

Q:Should the pressure gauge be mounted before or after the check valve at the back of the pump?: It should be the valve behind the exit because it can be replaced easily if damaged

Q:How can the PPR pipe be connected to the check valve?: The check valve and the PPR pipe are connected by two flanges to the clamp, and the clip type check valve and the two pipes (flanges) are clamped together directly with bolts.

Q:Can the slow stop disc check valve close quickly?: At the same time, the pressure of the inlet medium into the lower part of the piston in the oil cylinder to push the piston, the small end of the upper part of the oil cylinder piston through the needle valve are respectively pressed into both sides of the valve body, the piston rod extends out of the small cylinder. When the pressure of the inlet medium drops below the outlet pressure, the medium will produce a return flow.

Q:Why should the check pipe be added to the chilled water pipe of the air conditioning unit?: The air conditioning water chiller is usually installed in the basementNo check valve, pump start pressureThe current is likely to boil the pump when the building is high

Q:What is the function of the check valve?: 1. Check valve function: prevent backflow of medium, prevent pump and drive motor reverse, and discharge of container medium.2, check valve refers to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve.3, check valve according to the structure of the division, can be divided into lift check valve, swing check valve and butterfly check valve three:Lift check valve is divided into two types of vertical and horizontal.Swing check valve is divided into single, double valve and multi flap type of three.Butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.4, check valve (Check, Valve) installation should pay attention to the following mattersA do not allow the check valve to bear weight in the line, and the large check valve shall be independently supported so as not to be affected by the pressure generated by the piping system.B, when installing, pay attention to the direction of the flow of medium should be in accordance with the direction of the body marked arrow.C and vertical vertical check valves shall be installed on the vertical pipe.D and lift type horizontal check valves shall be installed on horizontal pipes.

Q:What kind of valve does the check valve belong to?: 1. check valves are automatic valves;2., if the valve is cast iron, can be cast iron valves; if the valve is cast steel, can be cast steel valves; of course, can also beIn copper valves, stainless steel valves,,,,,,,3., if used in steam, can belong to the steam valve
