进口双闸板闸阀-美国阿卡迪亚品牌

进口双闸板闸阀Product Description:

Poor high-temperature and high-pressure resistance and general service strength. Both sides of the lower part of the valve body are installed with rams, one side of the two rams is installed with connecting plates, and a pressure plate is installed between the two connecting plates. The inside of the pressure plate is provided with a connecting pipe, the inside of the ram is provided with a first through hole, and the inside of the connecting plate is provided with a second through hole. The upper and lower ends of the connecting pipes are installed with elastic blocks, and the upper and lower ends of the elastic blocks are installed with pressure springs, The upper and lower ends of the pressure spring are equipped with connecting pieces, the two sides of the pressure plate are equipped with clamping blocks, the front end face of the connecting plate is equipped with a limit plate, the upper part of the pressure plate is equipped with a connecting shaft, the outer part of the valve body is equipped with a connecting flange, and the outer part of the ram is equipped with a sealing gasket.

进口双闸板闸阀characteristic:

The double gate valve is applicable to the pipeline with water and sewage as the closed-circuit equipment and is not allowed to be used for regulating the flow and emptying. The gate valve: the parallel double gate valve is applicable to the pipeline with water and sewage as the closed-circuit equipment and is not allowed to be used for regulating the flow and emptying. It is widely applicable to the petroleum, chemical, pharmaceutical, electric power and other industries. The nominal pressure is ≤ L 0mpa steam, water, oil and other medium pipelines are used for opening and closing, including parallel double gate valve, parallel single gate valve, rising stem parallel double gate valve and rising stem parallel single gate valve. The working principle of the parallel double gate valve is to use the external power provided by the air cylinder or handwheel to drive the valve plate to move up and down to realize the opening and closing of the valve, In the process of valve opening and closing, the valve plate and the valve seat are in close contact with each other by virtue of the pre tightening force of the spring set between the double rams to achieve sealing.

进口双闸板闸阀Principle:

For the setting of overpressure plate, when the gate valve is working, the handwheel is rotated to drive the connecting shaft and the pressing plate to press the connecting plate. The triangular clamping blocks on both sides of the pressing plate play a certain role in buffering the connecting plate, so that the rams on both sides expand outward. The rams are embedded in the groove below the inside of the valve body. The sealing work is carried out by the external sealing gasket. The connecting pipe inside the pressing plate can drive the ram and the connecting plate to move up and down, In addition, when the water pressure and water temperature inside the valve body are high, when the pressure plate is pressed down, the elastic blocks and pressure springs above and below the connecting pipe can buffer the pressure plate to a certain extent to further reduce the water pressure strength, so that the connecting pipe has a certain pressure to limit the water pressure when it is moving, thereby improving the strength of the ram and facilitating long-term use.
