When the size of the valve gauge is detected, firstly, a qualified valve is taken as a standard sample, the disc part of the qualified valve is placed in the tool with the rod part facing upwards and the rod part facing downwards, after the standard sample is placed, part of the rod part of the valve standard sample is inserted into the barrel sleeve, so that the valve standard sample can be stably positioned in the tool, the disc part of the valve standard sample is supported by the upper surface of the ring gauge, at the moment, the dial gauge is placed on the upper end surface of the disc part of the valve standard sample for measurement and zero calibration, then the dial gauge is removed, the valve standard sample to be detected is placed in the tool in the same mode, the dial gauge is placed on the upper end surface of the disc part of the valve to be detected again, the pointer offset value is read, when the value is smaller than the product tolerance requirement, the product is qualified, and when the.

Further, the ring gauge comprises a flange and a body which are integrally formed and connected, the body is arranged in the cylinder in a penetrating mode and attached to the inner circumferential surface of the cylinder, and the flange is attached to the upper surface of the cylinder on the upper portion of the body.

Furthermore, the ring gauge and the cylinder body are in transition fit.

Further, the barrel sleeve and the barrel body are in transition fit.

Preferably, the fastener is provided in plurality, and the fastener is a half-head screw.

Has the advantages that: compared with the prior art, the utility model has the advantages that: the ring gauge is used as a reference for detection, the operation is simple and convenient, the detection efficiency is improved, the production efficiency is also improved, the self-detection frequency of operators is improved, the risk of batch out-of-tolerance in the machining process is reduced, the detection result is accurate, and the detection repeatability and the reproducibility are good; the tool is convenient to assemble and easy to process.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The invention will be further elucidated with reference to the drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention.

A valve gauge detection tool is shown in figure 1, and comprises a cylinder body 1, a ring gauge 2, a cylinder sleeve 3, a gasket 4 and a fastener, wherein the fastener is a half-round head screw.

The ring gauge 2 comprises a flange 21 and a body 22 which are connected in an integrated forming mode, the flange 21 is arranged on the outer peripheral face of one end of the body 22, the ring gauge 2 penetrates through the barrel 1 from the top of the barrel 1, the body 22 is located inside the barrel 1, the outer peripheral face of the body 22 is attached to the inner peripheral face of the barrel 1, the flange 21 is attached to the upper surface of the barrel 1 above the body 22, and the body 22 is in transition fit with the barrel 1.

The barrel sleeve 3 is arranged in the barrel body 1 in a penetrating mode from the bottom of the barrel body 1, the outer circumferential surface of the barrel sleeve is attached to the inner circumferential surface of the barrel body 1, the lower end of the barrel sleeve is flush with the bottom surface of the barrel body 1, the barrel sleeve 3 is in transition fit with the barrel body 1, the gasket 4 is fixed to the bottom surface of the barrel body 1 through a plurality of fasteners at the joint surface of the barrel sleeve 3 and the barrel body 1, the gasket 4 supports the barrel sleeve 3, and the diameter of the inner ring of the ring gauge 2 is larger than that of the inner.
