Electromagnetic valve capable of freely selecting modes

Abstract

The invention discloses an electromagnetic valve capable of freely selecting modes. The electromagnetic valve comprises a valve body and further comprises a plug. A first electromagnet and a second electromagnet are fixedly installed on the two sides of the valve body correspondingly. The inner side wall of the first electromagnet is movably sleeved with a connecting rod. The surface side wall of the connecting rod is fixedly sleeved with a piston. A first iron block and a second iron block are fixedly installed on the two sides of the connecting rod correspondingly. A first air inlet and a second air inlet are formed in the top of the valve body. A first air outlet, a working gas inlet and a second air outlet are formed in the bottom of the valve body. According to the electromagnetic valve, by additionally arranging the plug, a two-position five-way valve can be changed into a two-position three-way valve, the valve body does not need to be replaced, the two-position three-way valve does not need to be additionally purchased, and the product competitiveness of electromagnetic valve manufacturers can be improved through diversified selection; and clamping is conducted through a transmission mechanism by means of driving force generated by oil liquid entering, the stability of the mechanism is improved, an additional driving mechanism and driving force are not needed, and the production and use cost is saved.

Description

technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a solenoid valve with freely selectable modes. Background technique [0002] Solenoid valves are widely used in the current machinery manufacturing and life production. At present, the main solenoid valves used are mainly divided into two-position three-way solenoid valves and two-position five-way solenoid valves. The solenoid valve has a closed cavity, which can be opened at different positions. There are through holes, and each hole leads to different oil pipes. There is a valve in the middle of the chamber, and two electromagnets on both sides. The magnet coil on which side is energized, the valve body will be attracted to which side, and the gear is controlled by controlling the movement of the valve body. Different oil discharge holes are stuck or leaked, and the oil inlet hole is normally open, and the hydraulic oil will enter different oil discharge pipes, and the...

Problems solved by technology

[0003] However, the current mechanical production equipment has complex working conditions. According to different requirements, it is necessary to frequently switch between two-position three-way valves and two-position five-way valves. Most of the production and life are equipped with two-position five-way valves and two-position three-way valves at the same time. , but switching back and forth is not only costly, but also affects air tightness and work efficiency. Some of the two-position five-way valves are converted into two-position three-way valves by adding plugs to the two-position five-way valves, but ordinary plugs It is easy to be washed away by air pressure or oil pressure, causing leakage, which not only makes it difficult to improve production efficiency, but also increases later operating costs and failure rates
