Description

Technical Field

[0001] The utility model relates to the field of a special test bench for valves, and more specifically, to a special test bench for valves. Background Art

[0002] A portable valve test bench is a device used to test the performance and working status of valves under various operating conditions. It can test and analyze the opening and closing, sealing and flow performance of valves by simulating the actual use conditions.

[0003] A common portable test bench for valves usually includes a main test bench body, a test control panel and a test gas source pipeline. In order to ensure that the top pressure sealing disc on the moving plate can be quickly and well pressed against the flange of the valve for sealing, the moving plate is rigidly connected to the piston rod of the driving cylinder. Although the advantage of fast top pressure sealing is achieved, at the same time, due to the short stroke and no buffer, the top pressure sealing disc directly presses against the flange of the valve. If the operation is improper, it is easy to cause damage to the flange end face on the valve. In addition, due to the large stroke of the cylinder, it cannot be relatively fixed in a small space, which affects the use of the valve. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a valve-specific test bench that can be fixed more gently and within a space.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve-specific test bench, comprising a valve-specific test bench body, the valve-specific test bench body is provided with a test frame and a base, and is characterized in that: a connecting piece connected to the test frame is provided on the base, a locking groove and a locking piece are formed on the test frame, the locking piece is arranged around the locking groove and fixes the product, the locking piece comprises a locking block and a first driving block, the locking block slides on the test frame, the first driving block is connected and drives the locking block to move on the test frame, a driving cavity is formed in the first driving block, two driving parts are formed in the driving cavity and a driving surface is formed between the driving part and the first driving block, the driving part is formed with a locking section, the first driving block rotates on the test frame and drives the locking block to fix the product, and the locking groove is also provided with a positioning piece for locking the valve.

[0006] By adopting the above technical solution, the locking member is driven by the driving surface, and the valve body cannot be locked in a small space. At the same time, the stroke is relatively slow and will not damage the flange. The structure is simple, practical and convenient.

[0007] The utility model is further configured as follows: the positioning member includes a positioning block and a second driving block, the positioning block rotates on the test frame, a rotating rod is rotatably arranged on the positioning block and the rotating rods are all connected to the second driving block, a driving rod is slidably arranged on the second driving block, and a clamping portion is arranged on the end of the driving rod facing away from the test frame.

[0008] By adopting the above technical solution, the valve can be pre-positioned.

[0009] The utility model is further configured as follows: a first spring connected to the driving rod is arranged on the test stand.

[0010] By adopting the technical solution, the spring can be reset only when it is used.

[0011] The utility model is further configured as follows: a sealing portion is arranged at one end of the locking block, a plurality of sealing blocks are arranged on the sealing portion, the sealing blocks are arranged around the outer periphery of the sealing portion, and an adjusting piece is arranged on the locking piece.

[0012] By adopting the above technical solution, it can be fixed on the valve flange and protect the flange, while leaving holes to facilitate subsequent testing.

[0013] The utility model is further configured as follows: a sliding end is arranged at one end of the locking block facing away from the sealing portion, and the sliding section slides on the test frame and forms a limiting portion that cooperates with the driving portion.

[0014] By adopting the above technical solution, sliding is facilitated.

[0015] The utility model is further configured as follows: a clamping block and a clamping spring are arranged on the locking section, the clamping spring is connected to and drives the clamping block to move, and the limiting portion is recessed with a matching clamping groove.

[0016] By adopting the above technical solution, it is convenient to limit the position.

[0017] The utility model is further configured as follows: the adjusting member includes a driving tooth, the driving tooth is arranged on the outer periphery of the first driving block, the base is also provided with a driving tooth meshing with the first driving block, and a driving actuator is arranged on the driving tooth.

[0018] By adopting the above technical solution, the structure is simple, the driving operation is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS
