What are the different functions of electric gate valves according to their structural forms? Answered

The switch action position of the electric gate valve may be intermediate disassembly, the movement of the teeth is easy, and easy to protect, because the early body process is buffered with silver, and it is not easy to get stuck and damaged, but there must be a source of fire, and it is also more complicated than the control of the electric valve. . This type of valve should be installed in the water pipe as usual.

  Electric gate valve consists of electric actuator and valve. The electric valve is powered by electric energy and drives the valve through an electric actuator to complete the stroke of the valve switch tail. In order to achieve the purpose of connecting the pipeline medium.

  Electric gate valve is a variety of electric valves; it is the glory of the electromagnetic wire economic method. It pulls the valve core by pulling the magnetic field of the valve core, thereby changing the break on the valve body. The channel stone on the line is powered off and the valve core springs. Brickyard returned.

  Electric gate valves can be divided into open stem gate valves and concealed stem gate valves according to their structural forms. The functions of the two structures are not different, but what is more different is the use environment.

  1. The valve stem of the open stem gate valve is exposed. When opening and closing the valve, the opening and closing status of the valve can be visually observed to avoid misoperation. And because the valve stem is exposed, the original height of the valve stem is used to open the gate valve, so the height of the valve stem is relatively large. Therefore, the opening and closing stem gate valve is suitable for occasions that require a large amount of working space, and is not suitable for conditions with small space.

  2. The valve stem is hidden inside the gate valve body, so it is impossible to directly observe the status of the valve. However, due to the stem cells in the valve body, the volume of the concealed stem gate valve is smaller than that of the open bar gate valve, which is more suitable for use in small operating spaces, limited locations and dense pipelines.

  When the electric gate valve is fully open, there is no resistance when the medium flows through the valve body channel, and the flow resistance is almost zero. In addition, the electric gate valve body channel is symmetrical on both sides, and the medium can flow in both directions, and is not affected by the flow direction of the medium during installation. Electric gate valves have wide application prospects due to their excellent manufacturing technology. Gate valves are widely used in water conservancy systems, water supply and drainage systems, petroleum, chemical industry, electric power, urban construction, fire protection and other industries.
