Electric pilot piston valve for remote control

Abstract

The invention discloses an electric pilot piston valve for remote control. The electric pilot piston valve comprises a box body, a push connection inner cavity is formed in the box body, centrosymmetric sliding blocks are arranged in the push connection inner cavity in a sliding mode, a middle matching box body is fixedly arranged between the sliding blocks, and an open semicircular concave cavityis formed in each sliding block; and one side of each semicircular concave cavity is provided with a side connecting hole communicating with the push connection inner cavity, the outer side of each side connecting hole is provided with a sleeve, the sleeves are fixedly connected with the box body in a matched mode, and the two sides of the push connection inner cavity are provided with pipeline inner cavities in a communicating mode. According to the electric pilot piston valve, various valve bodies are combined with the equipment, multidirectional dredging can be selected when the pipeline is blocked, and a crushing structure is arranged in the equipment so that residues or turbid liquid and the like in the pipeline can be fully crushed, and the pipeline is convenient to dredge.

Description

Technical field [0001] The invention relates to the technical field of piston valve equipment, in particular to an electric pilot piston valve for remote control. Background technique [0002] In general electric pilot piston valve equipment, most of them use an electric push rod to drive the corresponding blocking block to realize the on-off control of the channel inside the valve body. The control method in this process is relatively simple. In addition, the blocked piston and the blocked pipeline cannot be dredged in time, and the liquid flow direction inside the pipeline cannot be changed. In the general design, if the pipeline is blocked, it can only be achieved by removing the piston valve. The effective dredging of the pipeline increases the difficulty of disassembly and replacement of the piston valve, and when there are more turbid liquid and scum inside the pipeline, the above turbid liquid and scum cannot be fully broken and cleaned, so that the equipment is actually w...

Problems solved by technology

[0002] In the general electric pilot piston valve equipment, most of them use the electric push rod to drive the corresponding blocking block to realize the on-off control of the channel inside the valve body. In this process, the control method is relatively simple. , and it is impossible to clear the blocked piston and blocked pipe in time, and it is impossible to change the flow direction of the liquid inside the pipe. In general design, if the pipe is blocked, it can only be realized by removing the piston valve. The effective dredging of the pipeline increases the difficulty of disassembling and replacing the piston valve, and when there is a lot of turbid liquid and dross inside the pipeline, the above-mentioned turbid liquid and dregs cannot be fully broken and cleaned, so that the equipment can be used in actual work. Increased chance of getting stuck in the process, making equipment less reliable in operation
