Problems solved by technology
[0004] Since the piston will rub against the cavity for a long time and frequently, after a period of use, the wear and friction of the contact surface will increase, resulting in a decrease in accuracy, a decrease in response sensitivity, and a shortened service life. The existing design has been difficult to meet the requirements of the robot. Industry, automobile industry, and precision manufacturing require solenoid valve automation, precision, and service life

Embodiment Construction
[0011] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0012] figure 1 Shown is an embodiment of a novel high-precision electromagnetic valve of the present invention, including a valve body 6, a movable cavity 1 is arranged in the valve body, and a piston 2 connected to a driving piston rod is arranged in the middle of the movable cavity 1, so that The piston 2 is provided with a degaussing ring 3 and a spring 4. One end of the spring 4 is fixed on the piston 2, and the other end is pressed against the movable cavity 1. An oil-free self-lubricating bearing 5 is also installed in the movable cavity 1. The oil-free self-lubricating bearing 5 is arranged between the movable cavity 1 and the upper end o...

The invention discloses a novel high-precision electromagnetic valve which comprises a valve body. A movable cavity is arranged in the valve body, a piston connected with a driving piston rod is arranged in the middle of the movable cavity, a demagnetizing ring and a spring are arranged on the piston in a sleeved manner, one end of the spring is fixed on the piston while the other end of the same is abutted against the movable cavity, and an oilless self-lubricating bearing is mounted in the movable cavity and arranged between the movable cavity and the upper end of the piston. The oilless self-lubricating bearing is mounted inside the cavity of the electromagnetic valve to guarantee contact between the oilless self-lubricating bearing and the piston and reduce friction coefficient so as to prolong service life and improve flexibility and movement accuracy; after use, size of the electromagnetic valve can be reduced, and service life is prolonged by 100% while weight is increased not more than 2%. Service life of the electromagnetic valve in automobile industry is enabled to be identical with that of an automobile, so that automobile using and maintaining cost is reduced.
Description
technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a novel high-precision solenoid valve. 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 actuator and is not limited to hydraulic and pneumatic. It is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Solenoid valves can cooperate with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones in the robot industry, automobile industry, and precision manufacturing are check valves, safety valves, directional control valves, and speed regulating valves. [0003...
