Pneumatic twisted neck heat-resistant soft sealed bottom valve

What is the difference between the up display discharge valve and the tank bottom valve? The difference between the opening and closing stroke of the upper and lower exhibition types is that the opening and closing stroke is different, and the installation size varies. The opening and closing stroke of the upper and lower exhibition discharge valves is smaller, and the installation height is also smaller. The installation height of the rotating rod structure is small, and the plunger only rotates during the opening and closing process. It needs to determine the opening and closing and position of the valve based on the opening and closing position indicator.

What is the difference between the up display discharge valve and the tank bottom valve? Opening and closing torque 1. The upward sliding discharge valve opens with the valve disc moving upwards. When opening, the valve needs to overcome the force of the medium, and the opening torque is greater than the closing torque. 2. The downward sliding and plunger type discharge valves open when the valve disc (plunger) moves downward, and the direction of movement is the same as the medium force when opened, so the opening torque is smaller than the closing torque.

Performance and Usage Construction and Installation Points 1) The installation position, height, and inlet/outlet direction must meet the design requirements, and the connection should be firm and tight. 2) All types of manual valves installed on insulated pipelines must not have handles facing downwards. 3) Before installing the valve, a visual inspection must be conducted, and the valve nameplate should comply with the current national standard "General Valve Marking" GB 12220. For valves with a working pressure greater than 1.0 MPa and a shut-off function on the main pipeline, strength and tightness tests should be conducted before installation, and they can only be used after passing the tests.

During the strength test, the test pressure shall be 1.5 times the nominal pressure, and the duration shall not be less than 5 minutes. The valve shell and packing shall be qualified if there is no leakage. During the tightness test, the test pressure is 1.1 times the nominal pressure; The test pressure should meet the requirements of GB 50243 standard for the duration of the test, and it is considered qualified if there is no leakage on the sealing surface of the valve disc. This valve is easy to operate, free to open, and has flexible and reliable movement; The valve disc assembly and maintenance are simple, the sealing structure is reasonable, and the sealing ring replacement is convenient and practical
