Adjustable speed delay valve

Abstract

The invention discloses an adjustable speed delay valve, which relates to the technical field of valves. It includes a shell; the right part of the shell is connected with an input pipe; the right end of the input pipe is connected with a four-way pipe joint; the left end of the shell is connected with an output pipe; the left end of the output pipe is connected with a three-way pipe joint; the main flow pipe and the auxiliary The flow pipe is respectively connected to the top and bottom of the four-way pipe joint; a three-way valve is connected between the main adapter pipe and the auxiliary adapter pipe; the left end of the three-way valve is connected to a connecting pipe; a one-way valve is installed in the connecting pipe; The bottom end of the pipe is connected to the top of the tee pipe joint; the diameters of the main adapter pipe and the auxiliary adapter pipe are larger than the diameters of the main flow pipe and the auxiliary flow pipe; the piston is sealed and slidably inserted in the housing; the bottom of the outer side of the piston is There are through holes. The beneficial effect of the present invention is: by adjusting the pipe diameter ratio between the main adapter pipe and the auxiliary adapter pipe and the main flow pipe and the auxiliary flow pipe, the sliding speed of the piston along the casing is controlled, thereby controlling the opening and closing of the valve body Speed, ease of operation, and smooth use.

Description

technical field [0001] The invention relates to the technical field of valves. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the transmission of the conveying medium, and the valve will choose the appropriate type of valve according to the different usage scenarios. When it is necessary to control the opening and closing speed of the valve, A delay valve is usually used, but the opening and closing speed of the traditional delay valve is fixed, so it cannot be adjusted in speed, and its use is limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an adjustable-speed time-delay valve in view of the above technical deficiencies. The sliding speed of the piston along the housing is controlled by adjusting the pipe diameter ratio between the main adapter pipe and the auxiliary adapter pipe and the main flow pipe ...
