Description
Technical Field
The utility model relates to a valve body testing device.
Background
The service life of the valve body directly influences the performance of the installed products, and the valve body needs to test all batches of products after production so as to acquire the service life data of the valve body. The existing testing device for the valve body has single function and cannot test the valve body in a special environment. If the valve body is used on the gas stove, the common valve body testing device cannot simulate the use environment of the valve body in the gas stove because the use environment is high-temperature and high-humidity environment, and correspondingly relatively accurate test data cannot be obtained, so that the estimation of the service life of the valve body is directly influenced.
The utility model patent of China (patent application No. 201621450168.3) entitled CN206274283U, wherein the test bench comprises a fixed support, a sliding support and a simulation device, the simulation device is fixed on the fixed support, and the simulation device comprises a linear driving part, a rotary driving part connected to the output end of the linear driving part and a clamping jaw arranged at the output end of the rotary driving part. The sliding support provides dynamic positioning for the simulation device, so that the simulation device is kept in a stable state in the test. In the working process, the linear driving piece drives the rotary driving piece and the clamping jaw to move forwards together, so that the clamping jaw abuts against the valve body of the gas cooker to simulate the pressing action, and the pressing test of the valve body is realized. When the valve body is subjected to rotation test, the linear driving piece keeps an extending state, and the rotation driving piece drives the clamping jaw to rotate anticlockwise towards the opening of the gas stove valve body, so that the clamping jaw simulates the action of opening the gas stove valve body. In this patent, when the simulation device is tested, the valve body needs to be mounted on an additional device, and the clamping jaw in the simulation device cannot be accurately matched with the valve body, so that the assembly is relatively difficult. The simulation device also needs to be specially provided with a sliding support for supporting in the action process, and the structure is relatively complex. And small displacement inevitably occurs in operation, and the test result is affected by different pressing positions of the clamping jaw on the valve body each time. More importantly, when the detection test stand is installed, people are required to move to each station for installation, and the installation is inconvenient. The simulation device moves in the horizontal direction range, so that the occupied area of the device is large, and the set stations are limited. In addition, in the working process of the simulation device, the use environment of the valve body cannot be simulated, and the obtained test result has large error.
