A leak-proof liquid valve

Abstract

The invention discloses a leakage-proof type liquid valve. The leakage-proof type liquid valve comprises a valve shell, wherein the valve shell communicates with a water inlet pipe and a water outlet pipe in a penetrating manner, floating rods are movably arranged between limiting columns, and a floating ball is fixedly arranged at the end, far away from the water inlet pipe, of the floating rods; and push plates are movably arranged between symmetrical guide rails, a rack is fixed on the parts, the same side of a compression spring, of the push plates, a driving gear is movably meshed on the rack, a driven bevel gear is connected with a linkage gear through a second connecting rod, the linkage gear is movably meshed with a transmission gear, and the side, far away from the linkage gear, of the transmission gear is movably meshed with a driven gear. The leakage-proof type liquid valve can monitor the leakage condition of the water inlet pipe and the water outlet pipe at the position of a valve and the position of a valve joint, the monitoring range is larger, when leakage occurs, the valve can automatically trigger leaking stoppage devices in the water inlet pipe and the water outlet pipe, so that the reaction is rapid, meanwhile, the leakage at different positions can be effectively prevented, and the leakage-proof type liquid valve is more effective in multiple position leakage.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a leak-proof liquid valve. Background technique [0002] Existing liquid valves are limited by structural and design limitations. After long-term use, the sealing performance tends to become worse and worse, which is prone to dripping and leakage. A large amount of resources are wasted due to failure to find out in time, and maintenance It also takes time, and a lot of resources will be wasted during this waiting period, which undoubtedly greatly affects the performance and scope of application of the liquid valve. [0003] In the prior art, a new type of leak-proof valve with the application number "201610381116.3" includes a valve body, a bonnet is provided on the top of the valve body, a bonnet threaded hole is opened in the center of the bonnet, and a screw is embedded in the bonnet threaded hole. , the top of the screw is connected with a handle, the valve body is provided w...

Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The leak-proof valve needs manual operation, and the biggest loss caused by valve leakage is that the leakage cannot be found in time, so the effectiveness of the device is low, and the valve occurs. Leakage will still cause a lot of waste because it cannot be processed in time; 2. The device cannot cope with the leakage of the water inlet pipe and outlet pipe at the valve and valve joint, and its effect is limited
