The extended rod gate valve is one of the commonly used block valves, which is mainly used to put through or cut off the medium in the pipeline; Especially suitable for medium and large diameter pipe. The stem of the soft seal gate valve drives the stem of the gate to lift together. The transmission thread on the stem is outside the valve body. Therefore, the opening and closing and position of the gate can be determined intuitively according to the direction and position of the valve stem, and the transmission thread is easy to lubricated and free from fluid corrosion, but it requires a large installation space.
Features:
Valve stem lengthening, convenient for high position operation;
Smooth channel, flow coefficient is small;
Reliable sealing, light and flexible operation

Quick ball valve with internal and external polishing treatment, for food, medicine and other health conditions. There are two control modes: switch type and regulator type. Full diameter sanitary ball valve basically no flow resistance; Simple structure, small volume, light weight; Tight and reliable, it has two sealing surface, and the sealing surface material of the ball valve is widely used in various plastics, good sealing, can achieve complete sealing

1. Check valve refers to a valve whose opening and closing part is a round disc and acts to block the backflow of media by its own weight and medium pressure. It is an automatic valve, also known as check valve, check valve, return valve or isolation valve. The motion mode of valve disc is divided into lifting type and swing type. Lift check valves are similar in construction to globe valves, except that they lack a stem that drives the disc.
2, the medium from the inlet end (lower side) into, from the outlet end (upper side) out. The valve is opened when the inlet pressure is greater than the sum of disc weight and flow resistance. On the contrary, the valve is closed when the medium flows back.
3. Swing check valves have an oblique disc that rotates about the shaft and work in a similar way to lift check valves. The check valve is often used as the bottom valve of the pumping device to prevent the return of water. The combination of the stop valve and the stop valve can play the role of safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.

Table valve generally use ball valve, table valve after the cone type plunger valve.
Advantages of ball valve
Simple structure, small volume, light weight.
Fluid resistance is small, full diameter ball valve basically no resistance.
Good sealing performance. The ball valve has two sealing surfaces, and the sealing of the hard sealing ball valve is manually ground, until the spool and the sealing ring can be used. Like the corrosion resistant ball valve, the valve body cavity will be widely used a variety of plastics, good sealing performance, in the vacuum environment has been widely used.
Easy to operate. As a switch, cut off or change the flow of the medium of the valve, in use only need to rotate 90 degrees can, and the torque is small.
A wide range of applications and applications. Ball valve diameter from small to a few millimeters, large to a few meters, from really high altitude to high pressure can be used. Moreover, ball valves have been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation and rocket fields.

A bolt is a type of fastener composed of two parts, head and screw, used to fasten the connection of two parts with a through hole. It is an anchorage component that will be anchored to the hardened concrete substrate.

Quick connector is a connector that can connect or disconnect pipelines without tools. The quick joint can be divided into: quick joint with air, quick joint with oxygen fuel gas, quick joint with gas liquid sharing, quick joint with oil pressure, quick joint with inert gas, quick joint with cooling water temperature oil, quick joint with semiconductor.

U-shaped bend is also called bend pipe, it is also a kind of pipe, U-shaped bend is divided into cold simmering and hot simmering. Generally small and medium pipe diameter elbow can be obtained by cold bending; Large diameter pipe will need hot bending.- Wenzhou Yuzheng Valve Co.,Ltd

High platform ball valve and flange gate valve is the same type of valve, the difference is that its closing part is a ball, the ball rotates around the center line of the body to achieve the opening and closing of a valve. Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. - Wenzhou Yuzheng Valve Co.,Ltd
