Problems solved by technology
[0002] In the chemical industry and some other industries, there are many high-pressure pipelines, and valves are installed in these high-pressure pipelines. The valves currently used are generally gate valves or ball valves. These valves have the following shortcomings in practical applications: (1) The liquid and gas passages are connected to the threads of the valve body. Corrosive liquids and gases will corrode the threads and easily form a dead valve; (2) Manual operation is required, which is labor-intensive and time-consuming, and when the pressure in the pipeline is high, the valve will increase. In actual operation, this strength often exceeds the range of manpower, and special tools have to be borrowed, causing inconvenience
(3) It is not easy to realize remote unattended operation in inaccessible and remote areas

The invention relates to an electric high-pressure valve, which comprises a valve, a pushing device, and a connecting device that connecting the valve and the pushing device. Wherein, the pushing device comprises a pusher with a pushing rod and a pusher fixing support; the pusher is fixed on the fixing support; the valve comprises a valve base connected to the frame of fixing support, a valve rod sleeve mounted on the valve base, and a valve rod inserted into the valve rod sleeve; the valve rod can move up-and-down inside the sleeve; the lower part of valve rod is connected to the valve pin; the side wall of sleeve is fixed with a tube interface; the connecting device comprises a connecting rod, a valve rod fixing disc fixed on the upper part of valve rod, and a pushing rod fixing disc fixed on the upper part of pushing rod; the connecting rod is through the valve base, while its upper part is connected to the valve rod fixing disc and the lower part is connected to the pushing rod fixing disc. The invention uses electric control, with high-pressure load and unmanned operation.
Description
technical field [0001] The invention relates to a valve device, in particular to an electric high-pressure valve. Background technique [0002] In the chemical industry and other industries, there are many high-pressure pipelines, and valves are installed in these high-pressure pipelines. The valves currently used are generally gate valves or ball valves. These valves have the following shortcomings in practical applications: (1) The liquid and gas passages are connected with the threads of the valve body. Corrosive liquids and gases will corrode the threads and easily form dead valves; (2) Manual operation is required, which is labor-intensive and time-consuming, and when the pressure in the pipeline is high, it will increase the opening of the valve. In actual operation, this force often exceeds the scope of manpower, and special tools have to be borrowed, causing inconvenience. (3) It is not easy to realize remote unattended operation in remote and inaccessible areas. ...
