Bending resistance test device for valve

Abstract

The invention provides a bending resistance test device for a valve, belonging to the technical field of machinery and solving the problems of difficult operation of the bending resistance of the traditional valve, high cost and potential safety hazard existing in operation. The bending resistance test device for the valve comprises a base, a connecting rod 1 and a connecting rod 2, wherein a force applying mechanism is fixed on the base, one end of the connecting rod 1 can be connected with one end of the valve and the other end can be fixedly connected with the force applying mechanism, the force applying mechanism can ensure the connecting rod 1 to bear a radial action force when the force applying mechanism is operated; and one end of the connecting rod 2 can be connected with the other end of the valve, and a force measurer capable of measuring a radial force-loading value of the connecting rod 2 is arranged between the other end of the connecting rod 2 and the base. The bending resistance test device for the valve has the advantages of simple structure, small occupation space, convenient operation and accurate measurement values.

Description

Valve bending strength test device technical field The invention belongs to the technical field of machinery, and relates to a test device, in particular to a valve bending resistance test device. Background technique Valves are one of the commonly used engineering components in people's life and production. With the development of society and the advancement of science and technology, products are not only updated and upgraded, but also product quality testing has been widely valued. The country has promulgated relevant testing specifications for the testing standards of valves. For the bending resistance test of valves, GB / T8464-2008 has made a clear description, but the specific equipment used has not been explained in detail. In the actual inspection process, first of all, a pipe fitting is generally tightened at both ends of the valve and supported at a suitable position; then an object of appropriate weight is used to act on the valve body. This traditional method i...

Problems solved by technology

In the actual inspection process, first of all, a pipe fitting is generally tightened at both ends of the valve and supported at a suitable position; then an object of appropriate weight is used to act on the valve body. This traditional method is not only difficult to operate, but also costly. High, there are potential safety hazards at work
