Wafer Check Valve

Q:Can the slow stop disc check valve close quickly?: Slow closing disc check valve does not turn off quickly."Slow closing" means slow closing and fast closing.The butterfly valve is mainly composed of a valve body, two semicircular discs, a return spring, an oil storage tank, a slowly closing small cylinder set, and a needle valve (a micro regulating valve). The principle relies mainly on the thrust of the imported medium and pushes the two discs smoothly.

Q:How to install industrial check valves? How should they be used?: 3, 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 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.

Q:What's the difference between the cut-off, check, check, and stop valves three? Better picture,: Stop check valve: when the handwheel is rotated so that the valve stem rises, the disc does not rise together, but only the valve clack is released.

Q:Is the tank stop valve a non-return valve or a check valve?: The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.

Q:The working principle and structure description of the mute check valve: Slow closing check valve and check valve or check valve, its role is to prevent the media back in the pipeline, its working principle is as follows: first, the role of principle: moving through the cylinder plug on the valve flap, assist the rapid opening and closing to the sealing surface two, structure 1 structural forms: swing type 2 single disc drive mode: 3 butt welding connection: open and closed by a pneumatic device to control the butt welding of the 4 valves, speeding up the valve opening and closing speed.

Q:What is the difference between the check valve rcvx and SFCV?: SFCV rubber check valve parts design mainly by the body, valve cover and rubber valve composed of three major parts. Its main features are: rubber valve in the valve by the steel plate, steel bar and reinforced nylon cloth as the substrate, the outer rubber covered, the valve switch life of up to 1 million times. H44X (SFCV) series rubber check valves adopt full flow area design. They have the characteristics of small head loss, easy accumulation of debris, easy maintenance and so on. H44X (SFCV) series rubber check valve is mainly suitable for horizontal installation of water supply and drainage system. It can be installed at the water outlet of the pump to prevent backflow and water hammer damaging the pump. H44X (SFCV) series rubber check valves can also be installed on the bypass pipe of the reservoir inlet and outlet to prevent backflow of water to the water supply system. Check valves are generally applicable to clean media and are not suitable for media containing solids and viscosity.Analysis of the main characteristics of RCVX rubber valve check valve: the valve body, valve cover, valve and spring, mainly used for pipeline industry departments of water supply and drainage system, oil and chemical exports, to prevent the media counter. Due to the design of the sealing ring of the product, the closing time is short, and the water hammer pressure can be reduced. The valve is made of nitrile rubber and steel plate by high temperature. It is resistant to erosion and has good sealing performance. The product structure is simple, and the maintenance, maintenance and transportation are very convenient.

Q:Check valve symbols?: The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve:1. lift check valve is divided into two types of vertical and horizontal.2. swing check valve is divided into single, double flap and multi flap type of three.3. 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.

Q:What is the HC41X-16Q model of the optical valve? What is its main function?: the medium back, due to weight and disc valve by the medium reverse force, so that the sealing surface of the valve flap and valve seat sealing and closed, to prevent the media counter to.1, fluid flow is smooth, local head loss is small;2 、 with guiding device, closed flexible, linear sealing, good return effect, can effectively reduce noise;3, small size, light weight, easy installation and maintenance.

Q:What does the swing check valve "h44h-16" mean?: Swing check valve with the built-in rocker swing structure, all opening and closing parts are arranged in the valve body of the valve, the valve does not penetrate, in addition to the seal gasket and seal ring with flange, overall no leak, to prevent leakage of the valve may be. Swing check valve rocker and disc connections using spherical connection structure, so that the valve in the 360 degrees within a certain degree of freedom, there is appropriate micro position compensation.

Q:Circulating water check valve, I want to ask is not greater than DN600, you can use HBH747H hydraulic butterfly valve closed butterfly valve, less than DN600 of HD43X slow butterfly butterfly check valve, what does hydraulic check mean? Need hydraulic?: Greater than DN600, you can use HBH747H hydraulic butterfly butterfly valve closed, less than DN600 with HD43X slow butterfly butterfly check valveThis is the usual selection, not necessary, there is no provision, but this choice is not wrong. There are, of course, other types of check valves.The hydraulic check valve is hydraulic, and the Baidu library contains instructions for the HB series and the HD series hydraulic check valves
