Description

Technical Field

[0001] This utility model belongs to the field of diaphragm valve technology, and specifically relates to a diaphragm valve durability testing platform. Background Technology

[0002] Diaphragm valves are a common type of shut-off valve, including manual diaphragm valves and pneumatic diaphragm valves. Diaphragm valves generally need to undergo durability testing before leaving the factory. This durability testing is usually done manually, which has disadvantages such as wasting manpower and increasing costs.

[0003] Currently, existing technologies include manual valve testing systems to replace manual testing. For example, patent CN118329418A discloses a valve testing system, including: a valve to be tested, comprising a valve body and a handle that cooperate with each other, the handle being rotatable relative to the valve body to open or close the valve; a valve mounting plate, on which the valve body is mounted; and a drive mechanism for driving the handle, enabling the handle to reciprocate relative to the valve body. The valve mounting plate is used to mount the valve to be tested, and the drive mechanism drives the handle to reciprocate relative to the valve body, thereby achieving the test of the valve's operating life during opening and closing. This testing system is reliable, low-cost, easy to install, and compact in structure, and can be used for manual valves that require extensive testing to confirm their operating life.

[0004] The aforementioned patented structure can replace manual testing of manual valves, but it cannot complete the durability test of pneumatic valves; in addition, the structure of the valve fixing plate is relatively complex and cumbersome to operate. Utility Model Content

[0005] This invention provides a diaphragm valve durability testing platform, which can solve the problems pointed out in the background art.

[0006] A diaphragm valve durability testing platform includes a platform body, on which a manual valve fixing component and a manual valve driving mechanism, as well as a pneumatic valve fixing component and a pneumatic valve driving mechanism, are respectively provided. The manual valve driving mechanism is used to drive the handwheel of the manual valve, so that the handwheel can reciprocate relative to the valve body. The pneumatic valve driving mechanism intermittently vents air to the pneumatic valve to drive the pneumatic valve to continuously open and close.

[0007] Preferably, the manual valve drive mechanism includes a power element and a handwheel mold. The handwheel mold is connected to the power output end of the power element and matches the handwheel to drive it to reciprocate.

[0008] Preferably, the handwheel mold is a mold cylinder, the handwheel is embedded in the mold cylinder, and the mold cylinder is provided with a limiting profile that matches the handwheel.

[0009] Preferably, the power component is a geared servo motor.

[0010] Preferably, the pneumatic valve drive mechanism includes an air supply system and a solenoid valve, through which intermittent air supply is controlled.

[0011] Preferably, both the manual valve fixing component and the pneumatic valve fixing component are self-centering bench vises.

[0012] Beneficial effects: This utility model provides a diaphragm valve durability testing platform that integrates the testing of manual diaphragm valves and pneumatic diaphragm valves into one testing platform. It can complete the testing of both types of diaphragm valves and has the advantages of simple structure, convenient operation, and labor saving. Attached Figure Description
