Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to a valve assembly table. Background Technology

[0002] Valves are widely used in fluid transport pipelines. The sealing performance of the valve itself plays a crucial role in the normal use of the valve. Currently, the valve assembly process generally involves assembling the valve first and then transporting it to the testing device for sealing performance testing, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide a valve assembly table that can perform a sealing test simultaneously upon completion of assembly.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A valve assembly platform includes a workbench, an air pump, a pneumatic valve, a cylinder, and a mounting base. The pneumatic valve and the cylinder are fixed on the workbench. The pneumatic valve has an inlet pipe, a first outlet pipe, and a second outlet pipe. The inlet pipe is connected to the air pump. The cylinder has a first cylinder inlet connected to the first outlet pipe and a second cylinder inlet connected to the second outlet pipe. The pneumatic valve has a control rod that controls the opening and closing of the first and second outlet pipes. The cylinder has a piston rod that can extend and retract. A first mounting block is provided at the end of the piston rod. A first vent hole is provided in the middle of the first mounting block. An outlet branch pipe is provided on the first outlet pipe. The outlet branch pipe is connected to the first vent hole and is equipped with an outlet switch. A second mounting block corresponding to the first mounting block is fixed on the mounting base. A second vent hole is provided on the second mounting block. A vent pipe is provided at the end of the second vent hole away from the first mounting block. A water bucket is provided on the side of the second mounting block away from the first mounting block, and the vent pipe extends into the water bucket.

[0006] With the above structure, when assembling the valve, the valve seat and other external valve parts are fixed to the first mounting block, and then the valve core, valve stem and other parts are installed into the valve seat. The piston rod then clamps and connects the valve components together with the first mounting block and the second mounting block. Finally, the bolts are tightened to complete the valve assembly. Then, the vent switch of the vent branch pipe is opened, and gas enters the valve through the first vent hole. If the valve seal is poor, gas will leak from the second vent hole and enter the water in the bucket through the vent pipe, causing air bubbles to appear in the water. If the seal meets the requirements, no air bubbles will appear in the water in the bucket. This utility model allows for convenient and quick valve assembly, and the valve sealing performance can be tested quickly while the assembly is complete, saving time and effort and increasing efficiency.

[0007] Preferably, for ease of control of the vent switch, the vent switch is a solenoid valve.

[0008] Preferably, in order to improve the sealing between the valve and the first mounting block and the second mounting hole and ensure the test results, a sealing ring is provided on the side of the first mounting block facing the second mounting block and the side of the second mounting block facing the first mounting block.

[0009] Preferably, to facilitate valve installation, a valve support block is fixed on the workbench, and the valve support block is located below the first mounting block and the second mounting block.

[0010] Preferably, in order to facilitate cleaning the workbench, an air gun is also included. A three-way pipe is provided between the air pump and the air inlet pipe of the pneumatic valve. The three-way pipe has three openings, which are respectively connected to the air pump, the pneumatic valve and the air gun. The air gun has a blow-up switch and an air blowing pipe.

[0017] In some examples, the air gun 23 is also included, and a three-way pipe 24 is provided between the air pump and the air inlet pipe of the pneumatic valve. The three-way pipe has three openings, which are respectively connected to the air pump, the pneumatic valve and the air gun. The air gun has a blow switch 25 and an air blowing pipe 26.

[0018] With the above structure, when assembling the valve, the valve seat and other external valve parts are fixed to the first mounting block, and then the valve core, valve stem and other parts are installed into the valve seat. The piston rod then clamps and connects the valve components together with the first mounting block and the second mounting block. Finally, the bolts are tightened to complete the valve assembly.
