Remote-controlled gate valve

Abstract

The invention discloses a remote-controlled gate valve. The remote-controlled gate valve comprises a valve body and a valve cover; a first groove is formed in the bottom of the valve body; a slag discharge pipe is arranged at the bottom of the first groove, and is provided with a first electromagnetic valve; an L-shaped support block is arranged in the first groove; second electromagnetic valves are respectively arranged at two ends of the valve body; first flanges are arranged on one sides of the second electromagnetic valves; the valve cover is arranged on the valve body; and second flanges are respectively arranged on two sides of the valve cover. The remote-controlled gate valve is provided with a control device and a driving device for controlling starting and closing of the gate valve and realizing cleaning of accumulated residues to achieve intelligent control effect, is provided with an audible and visual alarm for enabling maintainers to quickly find out faults to timely remove the faults, is provided with a sealing rubber ring for guaranteeing excellent tightness of the connecting place of the valve body and the valve cover, and is provided with a guide block for preventing stirring of residues at the bottom of the valve body in floating of a medium.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a remotely controlled gate valve. Background technique [0002] Gate valve is one of the most common opening and closing valves, which mainly use the gate to control the connection and cut-off of the medium flow in the pipeline. The existing gate valve can be opened and closed by turning the thread of the hand wheel and the valve stem to move forward and backward, lifting or lowering the gate connected to the valve stem, and the replacement and maintenance are very troublesome. Manpower is required to operate. Usually, a complex pipeline network needs to be equipped with multiple gate valves. In this way, in the face of a complex pipeline network, it will not be displayed by manual operation. Therefore, it is necessary to invent a gate valve that can be remotely controlled to solve the above problems. Contents of the invention [0003] The object of the present invention is to...

Problems solved by technology

The existing gate valve can be opened and closed by turning the thread of the hand wheel and the valve stem to move forward and backward, lifting or lowering the gate connected to the valve stem, and the replacement and maintenance are very troublesome. Manpower is required to operate. Usually, a complex pipeline network needs to be equipped with multiple gate valves. In this way, facing a complex pipeline network, it will not be displayed by manual operation. If there is a failure, the staff will have to check one by one, which is time-consuming and laborious.
