Abstract

An electric hydraulic shut-off valve, including a valve body and a valve core, a valve seat is arranged in the valve body, a conical water permeable hole is arranged in the middle of the valve seat, a control rod is fitted on the valve core, a mounting platform is provided above the valve body, and a The electric driving mechanism is installed through the sealing ring and bolts. The electric driving mechanism includes a fixed bottom plate and a sealing cover. A vertical sliding sleeve structure is arranged in the middle of the fixed bottom plate. The threaded rod in the vertical direction is equipped with a screw sleeve, the control rod is fixed on the fixed base plate through a sliding sleeve structure, and the top of the control rod is welded to the screw sleeve through a connecting piece. The invention overcomes the shortcomings of the prior art, uses the driving device and the threaded rod to control the up and down movement of the screw sleeve, thereby driving the control rod welded with it to move up and down, and realizes electric control. Protect the shut-off valve body.

Description

technical field [0001] The invention relates to the technical field of water conservancy valves, in particular to an electric water conservancy stop valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Globe valve, also called cut-off valve, is the most widely used valve. The reason why it is popular is that the friction between the sealing surfaces is small during the opening and closing process, it is relatively durable, the opening height is not large, it is easy to manufacture, and it is easy to maintain. Convenient, not only suitable for medium and low pressure, but also suitable for high pressure; its closing principle is that relying on the pressure of the valve rod, the sealing surface of the valve core and the sealing surface of the valve seat water hole a...
