Check valve is to rely on the flow of the medium itself and automatically open and close valve disc, used to prevent the media flow back valve, also known as check valve, one-way valve, countercurrent valve, and back pressure valve. Check valve is a kind of automatic valve, its main function is to prevent media backflow, prevent pump and drive motor reverse, as well as the discharge of container medium. Check valves can also be used to supply lines in which pressure may rise to exceed system pressure in the auxiliary system.

Gate valves are characterised as having either a rising or a nonrising stem. rising stems offer a visual indication of valve function due to the fact the stem is connected to the gate such that the gate and stem upward push and lower together because the valve is operated. nonrising stem valves may additionally have a pointer threaded onto the upper end of the stem to suggest valve role, since the gate travels up or down the stem on the threads with out elevating or reducing the stem.

1. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is forbidden.
2. The double gate valve should be installed vertically (i.e. the valve stem is in the vertical position and the handwheel is at the top).
3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force).
4. Gate valve with transmission mechanism shall be installed according to the product instruction manual.
5.
Butterfly valve is a type of valve that uses a spherical butterfly plate as the opening and last component and turns with the valve stem to open, close and alter the fluid channel. the butterfly plate of the butterfly valve is set up in the diameter route of the pipe. in the cylindrical channel of the butterfly valve frame, the disc formed butterfly plate rotates around the axis of the valve stem at an perspective among 0 ° and 0 °. whilst the butterfly plate is at 0 °, the valve is closed, and when the butterfly plate is at ninety °, the valve is absolutely opened.
In production and life, the emergence of valves is that the utilization rate of their valves and accessories is getting higher and higher, such as check valves, check valves, electric butterfly valves, pneumatic butterfly valves, rubber soft joints, electric ball valves, one-way valves, and wafer butterfly valves. , filter, etc., which have brought great convenience to production and life.
1. Butterfly valve is composed of valve body, valve seat, valve plate and valve stem, and all fittings are exposed and can be seen at a glance; Ball valve is composed of valve body, valve core (a round ball) and valve stem. The position of valve core is inside the valve body, and only part of it can be seen by naked eyes, so the sealing performance of ball valve is better than that of butterfly valve.2. Butterfly valves are relatively simple in structure, and butterfly valves with low pressure are generally used. The zui high pressure of butterfly valves can only reach 64kg.
Gate valve is a kind of cut-off valve, which is used to connect or cut off the medium in the pipeline. Gate valve's opening and closing member gate, driven by the valve stem, extend the seat to do linear lifting movement.Advantages of the gate valve.1. low fluid resistanceBecause the valve body of the gate valve internal media channel is straight, the media flow through the gate valve does not change its flow direction, so the fluid resistance is small.2.
Electric butterfly valve means that the butterfly valve is equipped with an electric actuator, which controls the opening and closing of the valve through the electric energy provided by the power supply, so as to realize remote centralized control and automatic operation. Electric butterfly valve can be divided into flange type and disc type according to the connection method, which is an important execution unit in the field of industrial automation control.
1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, quick switch, 90 reciprocating rotation and small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing and sealing performance.2. Butterfly valves can transport mud, and the liquid accumulated at the pipe mouth is the least. Under low pressure, good sealing can be achieved. Good adjustment performance.3.
Check valve is a valve installed in the pipeline to prevent the backflow of media. Check valves can be used on many types of pipelines such as over water, oil and gas, etc.
The filter net adopts stainless steel double-layer net structure, which is durable, advanced in structure, small in flow resistance, convenient in sewage discharge, etc. It can be used in water, steam, oil, nitric acid, urea, oxidizing medium and other media. According to the user's needs, the mesh number of filter screen should be set, generally, the water supply network is 18-30 mesh, the ventilation network is 40-100 mesh, and the oil supply network is 100-480 mesh.
Advantage 1. The opening and closing is convenient, quick, labor-saving, low in fluid resistance, and can be operated frequently.2. Simple structure, small overall size, short structural length, small volume and light weight, which is suitable for large-diameter valves.3. Mud can be transported, and the liquid accumulated at the pipe mouth is the least.4. Under low pressure, good sealing can be achieved.5. Good adjustment performance. 6. When fully opened, the effective circulation area of the valve seat channel is large, and the fluid resistance is small.7.
