Abstract

The invention discloses a ridge type valve airtight testing device, comprising a pool; the central of the bottom of the pool is provided with a longitudinal groove; the left side of the groove is provided with a transverse sliding rail; a sliding block is installed inside the sliding rail in a sliding manner; a screw rod is clamped on the left end of the sliding block in a sliding manner; the left end of the screw rod passes through the pool; and the screw rod is in thread cooperation with the pool. The invention is simple in operation, low in cost, stable in safety, and reliable in testing effect. Compared with the prior art, the ridge type valve airtight testing device does not need to replace the test water, does not need to pressurize the water and the gas and simplifies the test difficulty and the test cost.

Description

A kind of test device for air tightness of ridge type valve

Technical field

The present invention relates to valve air tightness detection equipment technical field, is a kind of test device for air tightness of ridge type valve specifically.

Background technology

Valve is the control assembly in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.

For the valve of fluid control systems, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.

Before valve dispatches from the factory, in order to ensure valve mass, all need to carry out air-leakage test to each valve, existing valve detection apparatus structure is complicated, and water supply system cost is high, is unfavorable for popularizing.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of test device for air tightness of ridge type valve.

Technical matters to be solved by this invention realizes by the following technical solutions:

A kind of test device for air tightness of ridge type valve, comprise pond, described basin bottom central authorities are provided with the groove of a longitudinal direction, so that the gas in valve is emerged by groove, be provided with the slideway of a transverse direction on the left of described groove, described slideway is slidably fitted with a slide block, the left end active card of described slide block has a threaded rod, described threaded rod can rotate relative to slide block, and the left end of threaded rod is through pond, and threaded rod and pond adopt threaded engagement.

The right-hand member of described slide block is fixed with an arc-shaped clamp, the right side of described groove is provided with the trim ring being fixed on basin bottom of an arc, the right side in described pond is fixed with column sleeve, column is combined with in described column sleeve, described column can move up and down relative to column sleeve, described column sleeve is laterally provided with the register pin for being pressed on column side, described register pin is fixed on column sleeve by the mode of threaded engagement, the upper end of described column is connected with blind flange by hinged mode, during use, described blind flange is connected with external gas feed line.

During use, be placed on below trim ring by valve port, utilize trim ring by a side compression of valve, then rotate threaded rod, promote slide block and move right, the arc-shaped clamp on slide block is stuck in the left part of the lower end of valve.The vertical position of adjusting post in column sleeve afterwards, by the upper port place of valve cover enclosing cover at valve, then utilizes register pin to be fixed by column.

During use, valve-off, passes into gas by inner chamber on the upside of valve, and whether the inner chamber observed on the downside of valve has bubble to emerge in pond, if having, represents that valve seal is not tight.

The invention has the beneficial effects as follows: the present invention is simple to operate, cheap, safety and stability, tests reliable for effect, compared with existing equipment, need not change test water, need not pressurize, use instead gas boosting, simplify difficulty of test and testing cost for water.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.
