Problems solved by technology
[0002] The sealing surface of the triple eccentric butterfly valve is an elliptical cross-section formed by obliquely cutting the cone. When the existing special measuring tools for the butterfly plate sealing ring are used to measure the sealing ring, it is usually directly measured with a ruler, and the measurement effect is relatively poor. Poor, high error, unable to measure the inner ring and outer ring at the same time, the existing triple eccentric butterfly valve seat is usually directly connected to the pipeline, the sealing and protection effect is low

The invention provides a measuring tool special for a triple-eccentric butterfly valve seat and a butterfly plate seal ring. The measuring tool comprises a valve seat body, a protection mechanism, a seal ring body and a measuring mechanism. The protection mechanism is installed on the annular side face of the valve seat body. The seal ring body is assembled on the upper side of the valve seat body. The seal ring body is assembled on the lower side of the measuring mechanism. The protection mechanism comprises a fixed ring plate, a first connecting ring, a spherical positioning block, a guide block, a first spring, a pull rod, a connecting round pipe, a second connecting ring, a lead screw, a protection pipe, an elastic protection fabric and a cleaning rod. The measuring mechanism comprisesa left limiting block, a left supporting frame, a left hollow sleeve, a measuring rod, a left telescopic hose, an arc-shaped pressing plate, a slide rod, a second spring, a right telescopic hose, a right hollow sleeve, a connecting rod, a right limiting block, a right supporting frame and a slide plate. Compared with the prior art, the measuring tool has the advantages that the protection and sealing functions are realized, the measuring accuracy is improved, and repeated measurement can be conducted.
Description
technical field [0001] The invention is a special measuring tool for a valve seat and a butterfly plate sealing ring of a triple eccentric butterfly valve, and belongs to the field of valve equipment. Background technique [0002] The sealing surface of the triple eccentric butterfly valve is an elliptical section body formed by bevelling a cone. When measuring the sealing ring with the existing special measuring tool for the sealing ring of the butterfly plate, it is usually measured directly with a ruler, and the measurement effect is relatively low. Poor, high error, it is impossible to measure the inner ring and the outer ring at the same time, the existing triple eccentric butterfly valve seat is usually directly connected to the pipeline, and the sealing and protection effect is low. SUMMARY OF THE INVENTION [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a special measuring tool for the valve seat of the trip...
