Problems solved by technology

[0004] In view of this, the object of the present invention is to propose a port flatness detection device for an emergency shut-off gate valve to solve the problem that some production enterprises in the prior art mainly rely on a flatness measuring instrument to detect the single-port flatness of the emergency shut-off valve. Its inspection costs are high, it takes a long time, and the professional requirements are high, so the number and number of flatness inspections are very limited, which increases the risk of bad product outflow technical problems

Abstract

The invention discloses a port flatness detection device of an emergency cut-off gate valve, and relates to the field of emergency cut-off gate valves. The device comprises a test table board, a first motor, a bracket, a dial indicator and a stabilizing part, the end portion of the test table boar is provided with a test hole, the first motor is positioned right above the test hole, the output shaft of the first motor is in power connection with the stabilizing part, the dial indicator is positioned on the bottom end surface of the test table board, when an emergency cutting-off gate valve to be tested is stabilized by the stabilizing part during work, the first motor is started to drive the emergency cutting-off gate valve to be tested to rotate, during the rotation, the detecting head of the dial indicator is always in contact with the port of the emergency cut-off gate valve to be detected, so that the flatness of the port can be detected, the device has simple structure, easy operation, reduced inspection time, and no need of high professional requirements, therefore, the production enterprise can increase the number of times and the number of times of detecting the flatness of the port of the emergency cut-off gate valve, and the risk of flowing out of poor products is obviously reduced.

Description

technical field [0001] The invention relates to the field of emergency cut-off gate valves, in particular to a port flatness detection device for emergency cut-off gate valves. Background technique [0002] Emergency shut-off valve, also known as safety shut-off valve, means that in the event of an emergency, the valve will be quickly closed or opened to avoid accidents. The slam shut-off valve has excellent technical performance, low load loss and high reliability. It is suitable for combustible gases such as coal gas, natural gas and liquefied petroleum gas, and is widely used in the safety facilities of gas supply pipe network system, gas thermal energy factory workshop, gas boiler room and residential residence. The gas emergency shut-off valve is a normally open pulse-triggered solenoid valve, which has the functions of self-locking and manual reset. [0003] The applicant found that some production enterprises mainly rely on the flatness measuring instrument to test ...
