Introduction to Swing Check Valve
The swing check valve is also called a check valve or check valve, its role is to prevent the medium in the pipeline from flowing backward. The opening and closing part is opened or closed by the flow of the medium and the force to prevent the medium from flowing backward is called a check valve. The non-return valve is an automatic valve. It is mainly used for pipelines where the medium flows in one direction. It only allows the medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline.

Application of valve:
The swing check valve is suitable for nominal pressure PN1.0MPa ~ 42.0MPa, Class150-2500; nominal diameter DN15 ~ 1200mm, NPS1 / 2 ~ 48; working temperature - 196 ~ 540 ℃ on various pipelines to prevent Media is flowing backward. By using different materials (WCB, CF8 (M), CF3 (M), 1Gr5Mo, 15CrMo1V, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea. It is mainly used for petroleum, chemical, pharmaceutical, fertilizer, power, and other pipelines.
The swing check valve adopts a built-in swing-arm swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the gasket and seal ring in the middle flange, the whole There is no leakage point, preventing the possibility of leakage of the valve. Swing check valve rocker arm and valve disc adopt a spherical connection structure, so that the valve disc has a certain degree of freedom within a 360-degree range, with appropriate micro-position compensation. Suitable for clean media, not suitable for media with solid particles and high viscosity.
Structural features of the swing check valve:
1. The structure length is short, and its structure length is only 1/4 ~ 1/8 of the traditional flange check valve
2. small size, lightweight, its weight is only 1/4 ~ 1/20 of the traditional flange check valve
3. The valve flap closes quickly and the water hammer pressure is small
4. Both horizontal and vertical pipes can be used, which is easy to install
5. The flow channel is unobstructed and the fluid resistance is small
6. sensitive action, good sealing performance
7. Short stroke of the valve and small impact force when the closing valve
8. the overall structure, simple and compact, beautiful appearance
9.Long service life and high reliability
The working principle of the swing check valve:
Through the up and down movement of the cylinder plug, the valve flap is opened and closed quickly to achieve the sealing surface
A structural form: single swing flap
B drive method: butt welding connection
C connection form: butt welding connection
The opening and closing of the D valve are controlled by a pneumatic device to speed up the opening and closing of the valve.
Maintenance and maintenance of swing check valve:
1 The valve should be stored in a dry and ventilated room to prevent moisture, rain, and rust.
2 The storage and opening and closing parts should be in the closing device during storage and transportation.
The valve flap should be fixed to open, and the inner ports at both ends of the diameter should be blocked with foam boards. The ports must be plugged tightly to prevent dust and rust, to keep the passage clean and the end surface flat. And anti-collision; the valve should be stable when placed,
The pneumatic drives are facing up and must not be squeezed against each other.
3 It should be checked regularly when it is left for a long time. Every three months, check the dirt and rust on the two channels, the sealing surface, and the protection of the welding joint. After wiping the dirt and rust, apply anti-rust oil to protect it.
The swing check valve can be installed horizontally or vertically. The swing check valve flap rotates around the axis of rotation. Its fluid resistance is generally smaller than that of a lift check valve. It is suitable for large-caliber occasions, and its installation position is not affected. Restricted, usually installed in horizontal pipelines, it is suitable for occasions with larger calibers. According to the number of valve flaps, it can be divided into three types: single-lobed revolving, double-lobed, and multi-lobed. A single flap swing check valve is generally used on the occasion of medium caliber. When large-diameter pipelines use single flap swing check valves, in order to reduce water hammer pressure, it is best to use slow-closing check valves that reduce water hammer pressure. A double flap swing check valve is suitable for large and medium diameter pipelines. Wafer double flap swing check valve has a small structure and lightweight and is a fast check valve. The multi-flap swing check valve is suitable for large diameter pipelines.
