Bevel gear stainless steel gate valve,stainless steel gate valve. gate valve

Product Introduction: Bevel gear gate valves and flanged gate valves belong to the same type of valves. The difference lies in that the closing part of the bevel gear gate valve is a ball, which rotates around the centerline of the valve body to achieve opening and closing. Gate valves are a new type of valve mainly used for cutting off in pipelines and are widely adopted. Generally, this type of valve should be installed horizontally in pipelines. American standard gate valves are mainly used in pipelines for cutting off, distributing and changing the flow direction of the medium. Gate valves are a new type of valve that has been widely adopted in recent years. They have the following advantages:

one The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

2 Simple structure, small volume and light weight.

3 It is tight and reliable. Currently, plastic is widely used as the sealing surface material of gate valves, which has good sealing performance and has also been widely used in vacuum systems.

4. It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for remote control.

5 The gate valve is easy to maintain. It has a simple structure and the sealing rings are usually movable, making disassembly and replacement relatively convenient.

6. When fully open or fully closed, the sealing surfaces of the gate body and the valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve's sealing surfaces.

The American standard gate valve is a relatively new type of gate valve category. It has some unique advantages due to its own structure, such as no friction during opening and closing, the seal is not easy to wear, and the opening and closing torque is small. This can reduce the specifications of the equipped actuators. When equipped with a multi-turn electric actuator, it can achieve the regulation and tight cutting off of the medium. It is widely applicable to working conditions such as petroleum, chemical industry, urban water supply and drainage, etc., where strict shut-off is required. Structural features of American standard gate valves:

1. No friction when opening and closing. This function completely resolves the issue of traditional [wiki] valves [/wiki] affecting sealing due to mutual friction between sealing surfaces.

2. Upper-mounted structure. Valves installed on pipelines can be directly inspected and maintained online, which can effectively reduce the downtime of the equipment and lower costs.

3. Single-seat design. The problem that the medium in the middle cavity of the valve was affected in terms of usage safety due to abnormal pressure increase has been eliminated.

4. Low-torque design. The valve stem with a special structure design can be easily opened and closed with just a small handle.

5. Wedge-shaped sealing structure. Valves are sealed by the mechanical force provided by the valve stem, which presses the ball wedge onto the valve seat. This ensures that the sealing performance of the valve is not affected by changes in pipeline pressure difference, and its sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of the sealing surface. When the ball tilts off the valve seat, the fluid in the pipeline passes uniformly at 360° along the sealing surface of the ball. This not only eliminates the local scouring of the valve seat by the high-speed fluid but also washes away the accumulated substances on the sealing surface, achieving the purpose of self-cleaning.
