Valve inner leakage detection device for chemical machinery

Abstract

The invention discloses a valve inner leakage detection device for chemical machinery. Thevalve inner leakage detection device comprises a valve shell, connecting pieces are mounted at the left end and the right end of the valve shell, and one end, far away from the valve shell, of each connecting piece is connected with a connecting pipeline; a fixing rod which is arranged above the valve shell, wherein the bottom of the fixing rod is connected with a valve plate, and the valve plate is arranged in the valve shell; microswitches which are installed on the inner walls of the connecting pieces; a second pull rope, wherein one end of the second pull rope penetrates through a third fixed pulley to be connected with a second balancing weight, and the third fixed pulley is installed on the outer wall of a sealing box. According to the valve inner leakage detection device for the chemical machinery, an inclined supporting block is arranged between the valve shell and a protection piece, and the supporting block is hollow, so that when leakage occurs in any direction of the valve shell, leaked liquid can flow into the sealing box and is collected, a floating plate moves upwards, and normal operation of the whole detection work is ensured.

Description

technical field [0001] The invention relates to the technical field of chemical machinery, in particular to a valve internal leakage detection device for chemical machinery. Background technique [0002] In the chemical machinery industry, valves are relatively common appliances, mainly used to control the flow rate of fluids. There are many types of valves on the market at present, which can be selected according to the actual needs. During the use of valves, sometimes Leakage occurs, which will cause fluid loss and waste, so a detection device is required to detect internal leakage of the valve. [0003] For example, the publication number is CN213271306U, a valve internal leakage detection device for chemical machinery, a leak opening is provided on the bottom surface of the valve, which can make the liquid flowing in the closed state of the valve slide down, pass through the collection frame provided, and between the observation window With cooperation, the liquid after...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a valve internal leakage detection device for chemical machinery, to solve the problem that the detection device on the market currently on the market proposed by the above-mentioned background technology is troublesome to perform internal leakage detection by viewing, which increases the workload of the staff, and It is not convenient to automatically alarm and remind the staff according to the liquid leaking inside, which reduces the automation effect of the detection device, thereby reducing the use efficiency of the detection device
