Description

Experimental frock of sealing washer

Technical Field

The utility model relates to an experimental frock, especially a sealing washer is experimental frock.

Background

As the most key sealing element for the valve, the sealing ring is high in price, the requirement on the sealing part of an installation tool part is strict, and three leakage channels for causing leakage in the valve are arranged according to the structure and the sealing mechanism of the fixed ball valve; firstly, the leakage between the sealing ring and the ball sealing pair, secondly, the leakage of the matching part of the sealing ring and the valve seat metal fixer, and thirdly, the leakage of the matching part of the sealing ring, the valve body and the valve seat fixer.

The existing sealing ring test tool can only perform performance test on the sealing rings with the same size and specification, and test tools with different specifications need to be designed for the sealing rings with different specifications, so that the manufacturing cost of the tool is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the prior art not enough, the utility model provides a sealing washer test fixture.

The technical scheme of the utility model a sealing washer test fixture, including the frock disk seat, the frock valve body, be equipped with seal gasket between frock disk seat and the frock valve body, the cylinder spigot surface is processed into to the head of frock disk seat, the spigot surface rear end is equipped with the shaft shoulder of at least one installation sealing washer, frock valve body bottom is equipped with the direction hole with cylinder spigot surface complex, direction hole rear end is equipped with the circular bead hole of mutually supporting with the shaft shoulder, the epaxial terminal surface processing plane of frock valve body outside, be equipped with the blind hole I with I looks adaptation of test tube on the plane, test tube I links to each other with needle valve I, I bottom of blind hole is equipped with the communicating air vent I with frock valve body passageway, circular bead inner hole department is arranged in to air vent I, tooling disk seat bottom excircle facing (operation) plane, be equipped with the blind hole II of II looks adaptations of test tube on the plane, test tube II links to each other with needle valve II, the groove department of the frock disk seat between seal gasket and the sealing washer is equipped with the communicating air vent III.

Preferably, the shaft shoulder and the inner hole of the shoulder are matched with each other, and a sealing ring idle stroke is reserved in a space.

Preferably, the roughness of the outer circle surface of the shaft shoulder and the surface of the inner hole of the shaft shoulder is not less than Ra0.2.

Preferably, all be equipped with the hole for hoist on frock disk seat, the frock valve body.

Preferably, test pipeline I and blind hole I, test pipeline II and blind hole II all welded connection.

The beneficial effects of the utility model are that, frock simple structure only just can accomplish with two work pieces and carry out the capability test to the sealing washer of different dimensions, greatly reduced manufacturing cost.
