Abstract
The invention relates to a test fixture structure for filtering materials. The test fixture structure comprises an upstream fixture and a downstream fixture, wherein ventilation cavities are respectively formed in the upstream fixture and the downstream fixture; an upstream sampling opening is formed in the upstream fixture; a downstream sampling opening is formed in the downstream fixture; a pressure relief valve and a pressure gauge are arranged on the upstream fixture. By adopting the structure, excessive gases in the upstream fixture can be conveniently exhausted by the pressure relief valve, so that the condition that the safety and the detection effect are influenced due to the fact that the excessive gases cause the risk is prevented; the test fixture structure is simple, and is convenient and practical.
Description
Technical field
The present invention relates to filtering material detection technique field, especially relate to a kind of filtrate test fixture structure.
Background technology
Fixture is used for fixing processing object in machine-building process, make it to occupy correct position, to accept the device of constructing or detecting, fixture is divided into universal fixturing and unit clamp, unit clamp is the particular jig produced for a certain product, and usually need to adopt unit clamp when detecting filtrate, clipping operation is completed by clamping filtrate between upstream fixture and downstream fixture at present when detecting filtrate, when in use, if media filtration performance is bad, and it is excessive to its gas passed into, the pressure increase in the fixture of upstream can be caused, danger can be produced when pressure is excessive, breaking likely appears in filtrate, the effect that impact detects.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of filtrate and can not breaks and can not produce dangerous filtrate test fixture structure.
The present invention solves the technical scheme that its technical matters takes: a kind of filtrate test fixture structure, comprise upstream fixture and downstream fixture, vented cavity is equipped with in described upstream fixture and downstream fixture, described upstream fixture is provided with sampled upstream mouth, described downstream fixture is provided with sampled downstream mouth, and described upstream fixture is provided with blowdown valve and pressure gauge.
Concrete further, described downstream fixture is provided with pressure charging valve.
Concrete further, described fixture comprises control chip, and described blowdown valve and pressure charging valve all adopt solenoid valve, and described blowdown valve and pressure charging valve are connected with control chip, and described pressure gauge is connected with control chip.
Concrete further, described blowdown valve adopts constant pressure relief valve.
Concrete further, the clamping end face of described upstream fixture is provided with an annular projection near vented cavity portion, and the clamping end face of described downstream fixture is provided with a circular step near vented cavity portion and coordinates with annular projection.
The invention has the beneficial effects as follows: after have employed said structure, can lay down gas unnecessary in the fixture of upstream very easily, prevent it from causing danger, affect safety and Detection results by blowdown valve, structure is simple, convenient and practical.
