Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, specifically relating to a two-position five-way electromagnetic valve. Background Technology

[0002] A 2-position 5-way solenoid valve is a pneumatic control element used to control the on / off state and flow direction of fluid (usually compressed air), and belongs to an important category of solenoid valves. Its core features are two working positions (two states of the valve core: on or off) and five ports (usually including 1 air inlet, 2 working ports and 2 exhaust ports), and it is widely used in the control of pneumatic actuators (such as cylinders) in industrial automation.

[0003] Specifically, in actual operation, a 2-position 5-way solenoid valve must strictly follow the established air circulation logic: compressed air is introduced through the inlet (marked P) as the power source, and the gas that has performed work is discharged through the exhaust port (usually R or S) under the corresponding operating condition. However, when the introduced gas contains impurities such as moisture, oil, metal shavings, and dust, these impurities will flow at high speed within the valve body with the airflow, creating continuous friction and erosion in key areas such as the fit gap between the valve core and the valve body, and the contact surface between the seals and the flow channel. Over time, this will not only cause wear on the valve core and aging and failure of the seals, leading to problems such as air leakage and cross-contamination within the valve, but also increase the valve core's switching resistance and slow down the response speed. In severe cases, it may even jam the valve core, preventing the solenoid valve from switching its working state normally. This not only directly affects the control accuracy and operational stability of the solenoid valve and shortens its service life, but may also cause the entire pneumatic system to shut down due to sudden failures, bringing the risk of production interruption and economic losses. Utility Model Content

[0004] The purpose of this invention is to provide a two-position five-way solenoid valve to solve the problem that when the incoming gas contains impurities such as moisture, oil, metal shavings, and dust, these impurities flow at high speed within the valve body with the airflow, causing continuous friction and erosion in key areas such as the fit gap between the valve core and the valve body, and the contact surface between the seals and the flow channel. Over time, this not only causes wear on the valve core and aging and failure of the seals, leading to problems such as air leakage and cross-contamination within the valve, but also increases the valve core's switching resistance, slows down the response speed, and in severe cases, may even cause the valve core to jam, preventing the solenoid valve from switching its working state normally. This not only directly affects the control accuracy and operational stability of the solenoid valve, shortening its service life, but may also lead to the shutdown of the entire pneumatic system due to sudden failures, posing a risk of production interruption and economic losses.

[0009] In order to improve the filtration effect, in a preferred embodiment of the two-position five-way solenoid valve of this utility model, the primary filter screen and the mounting groove on the inner wall of the filter block form a fitting structure.

[0010] To facilitate the stable installation of the primary filter, in the preferred embodiment of this two-position five-way solenoid valve, the primary filter is fitted into the groove on the inner wall of the filter block via a snap fastener.

[0011] To improve sealing, in a preferred embodiment of the two-position five-way solenoid valve of this utility model, a positioning groove is provided at the bottom end of the docking seat near the connector, and a sealing ring is connected to the inner wall of the positioning groove. The sealing ring is made of silicone.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
