Abstract
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
The present invention relates to Solenoid Valve Technology field, particularly a kind of Novel high-precision solenoid valve.
Background technique
Solenoid valve (Electromagnetic valve) is the industry equipment by Electromagnetic Control, is used to the automation foundation element controlling fluid, belongs to final controlling element, is not limited to hydraulic pressure, pneumatic.Be used in industrial control system adjust medium direction, flow, speed and other parameter.Solenoid valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system, robot industry, car industry, and what sophisticated manufacturing was the most frequently used is one-way valve, safety valve, position control valve, speed-regulating valve etc.
The general structure of solenoid valve has airtight chamber in being, through hole is had at diverse location, each hole connects different pipelines, piston in the middle of chamber, two sides is two blocks of electromagnet, which side the magnet coil energising valve body in which face will attracted to, open or close different oil extraction (gas) holes by the movement of control valve body, and oil-feed (gas) hole is often opened, hydraulic oil (gas) will enter different oil extraction (gas) pipes, then promoted the piston in cylinder by the pressure of oil (gas), piston drives piston rod again, piston rod driving mechanical device.Current switching like this by controlling electromagnet just controls mechanical motion.
Because piston rubbing with cavity of long-time high frequency time can there will be contact surface abrasion frictional force and become and cause precise decreasing greatly in use for some time, reaction sensitivity declines, the problems such as shortening in working life. existing design has been difficult to meet robot industry, car industry, sophisticated manufacturing is to solenoid valve automation, precision, the requirement in working life.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Novel high-precision solenoid valve that can improve its working life.
The present invention in order to the technological scheme solving its technical problem and adopt is: a kind of Novel high-precision solenoid valve, comprise valve body, movable cavity is provided with in described valve body, the piston connecting piston rod is provided with in the middle of movable cavity, described piston is arranged with demagnetization ring and spring, spring one end is fixed on piston, and the other end pushes against in movable cavity, also be provided with an oil-less self-lubricating bearing in described movable cavity, described oil-less self-lubricating bearing is located between movable cavity and the upper end portion of piston.
As a further improvement on the present invention, the weight of described oil-less self-lubricating bearing is less than 2% of solenoid valve total quality.
The invention has the beneficial effects as follows: Novel high-precision solenoid valve of the present invention, not only installing an oil-less self-lubricating bearing in the inside cavity of solenoid valve makes it ensure to contact but also lower friction factor thus improve working life with piston, sensitivity and movement high-precision, can make the volume of solenoid valve after using, making to promote working life 100%. when weight increase is less than 2% will be so that solenoid valve in automobile industry can be identical with automotive service life. reduce automobile and use. and cost of upkeep.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Indicate in figure: the movable cavity of 1-; 2-piston; 3-demagnetization ring; 4-spring; 5-oil-less self-lubricating bearing; 6-valve body.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 shows a kind of mode of execution of a kind of Novel high-precision of the present invention solenoid valve, comprise valve body 6, movable cavity 1 is provided with in described valve body, the piston 2 connecting piston rod is provided with in the middle of movable cavity 1, described piston 2 is arranged with demagnetization ring 3 and spring 4, spring 4 one end is fixing on the piston 2, and the other end pushes against in movable cavity 1, also be provided with an oil-less self-lubricating bearing 5 in described movable cavity 1, described oil-less self-lubricating bearing 5 is located between movable cavity 1 and the upper end portion of piston 2.Not only the weight of described oil-less self-lubricating bearing 5 is less than 2% of solenoid valve total quality, adds oil-less self-lubricating bearing 5 and makes movable cavity 1 and piston ensure to contact but also lower friction factor thus improve working life, sensitivity and movement high-precision.
