Problems solved by technology

[0003] Sleeves need to be installed on the outside of the iron core structure. The traditional sleeves need to be connected to the coil support and the gas nozzle. This makes the solenoid valve not only consider the assembly tolerance, but also consider the production tolerance, and the assembly tolerance is the key to control the yield. The main factor, and the existing upper solenoid valves on the market, the air inlet and outlet are basically set on the valve seat of the solenoid valve, rather than on the valve body of the solenoid valve, which is a problem when the solenoid valve is installed with other components. If the precision requirements are high, the design process of the solenoid valve will be more, and the yield will be reduced.

Abstract

The invention discloses an integrated solenoid valve casing, and a casing main body adopts injection molding in one time. The upper outer side of the casing main body is provided with an I-shaped segment and a working segment, while the casing main body is internally provided with a groove segment comprising a fixed groove segment with a large-diameter rear end, and a closed groove segment with a small-diameter front end; and the I-shaped segment comprises a first flange at the rear end and a second flange at the front end, and the working segment comprises a first sealing groove at the rear end, a pore groove at the middle part, a second sealing groove at the front end. According to the integrated solenoid valve casing disclosed by the invention, the one-piece injection molding technology is adopted, and an air inlet and an air outlet are integrated with the casing body, so that the connection of similar nozzle structures of the traditional casing body is replaced, and the installation accuracy with other components of a solenoid valve is recued; at the same time, the assembly requirements of the casing body are reduced, and the casing is also integrated with the mounting position of a coil; the method that the traditional casing is provided with a coil bracket additionally is replaced, and the assembly of the coil bracket is avoided; and the assembly tolerance is further reduced.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to an integrated solenoid valve casing. Background technique [0002] Solenoid valve (Electromagnetic valve) is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to the actuator and is not limited to hydraulic pressure and pneumatic. Similar to the valve structure. [0003] The outer side of the iron core structure needs to be equipped with sleeves, and the traditional sleeves need to be connected with the coil support and the gas nozzle. This makes the solenoid valve not only consider the assembly tolerance, but also consider the production tolerance, and the assembly tolerance is the key to control the yield. The main factor, and the existing solenoid valves on the market, the air inlet and outlet are basically set on the valve seat of the solenoid valve, rather than on the valve body of the solenoid valve, w...
