The cylinder is directly made of seamless thick-walled pipe, and one end of the head adopts a cylinder cap, which can withstand high pressure, and is easy to manufacture and saves costs. The other end of the cylinder is sealed with a flange, which can be connected to match the size of the cylinder Unique flange sealing reduces the amount of production and material consumption.

The flange interface is composed of flange interface a, flange interface b, flange interface c, flange interface d and flange interface e. Interface b, the right side of the flanged interface b is provided with a flanged interface c, the right side of the flanged interface c is provided with a flanged interface d, and the right side of the flanged interface d is provided with a flanged interface e. The number of flanged joints can be continuously increased, just add the length of the cylinder and the flanged joints; the size of the flanged joints increases sequentially from the right side of the cylindrical cap to ensure a better appearance.

The cylinder is tubular, and the wall thickness of the cylinder is 5mm-50mm. The test pressure level of the valve test fixed table can be continuously improved, and it is only necessary to thicken the cylinder and the joint.

The flanged interface adopts the neck butt welding flange and the connecting pipe butt joint type. The neck butt welding flange and the butt joint type can meet the requirements of high pressure working environment.

The medium inlet adopts an inner wire interface and is equipped with a wire plug.

The flanged joints are respectively provided with blind flanges corresponding to the specifications of the flanged joints.

The test medium is gas or liquid.

Its working principle is: multiple valves to be tested are hung on the corresponding flanged joints, and bolts are used to fasten the connection. The connection method is consistent with the connection method when the valve is in normal operation, which ensures the accuracy of the test. For each test, seal the unused flanged interface with a blind flange before the test to ensure that the entire test system is airtight. Each interface must be equipped with a blind flange of the corresponding size, and the test medium will pass through the medium inlet. Import the whole equipment, observe the pressure indication number after the medium enters the equipment, continuously increase the medium pressure until the pressure indication number reaches the test pressure, maintain the test pressure for a specified time, during this period, use soapy water to check the disc, valve stem seal, and flange of each test valve Wait until there are bubbles in the seal, if the pressure indication remains unchanged, all the test valves are qualified, otherwise the valves with bubbles are unqualified.

The beneficial effects of the utility model are: the utility model has the advantages of convenient fixing in place, wide application range and multiple valve tests can be carried out at the same time. The result is more accurate; the equipment connects multiple flange interfaces of different specifications on a cylinder, and multiple valves can be tested at the same time, and the fixing in place is much simpler, saving a lot of time and improving the test efficiency; Quantity can realize the valve test of different types and sizes, the application range is wide, the structure is much simpler than the traditional valve test fixed table, and the equipment manufacturing cost is low.
