Problems solved by technology

In order to reduce leakage, this type of valve designs the matching gap between the valve core and the valve sleeve to be very small. Such a small gap puts forward very strict requirements for the processing technology of the valve, which greatly increases the processing difficulty and processing cost.
[0009] In addition, such a small gap is also easily blocked by impurities, so its application is greatly limited

Embodiment Construction

[0024] As shown in the accompanying drawings, the present invention includes:

[0025] In the valve body 10 holes, from right to left, there are spring valve sleeves 22 with two groups of holes in the radial direction, eight-hole valve sleeves 18 with two groups of holes in the radial direction, and six-hole valve sleeves with a group of holes in the radial direction. Sleeve 17, a two-hole valve sleeve 12 with a group of holes in the radial direction, a regulating valve sleeve cover 24 is arranged on the small cylindrical surface at the right end of the spring valve sleeve 22, and the valve sleeve cover 24 is pressed against 22 spring valve sleeves protruding from the valve body 10 On the shoulder, the force amplifying mechanism 4 equipped with the dry DC electromagnet 5 is pressed on the left end face of the push rod 6, and one end of the spring stopper 23 installed in the spring valve sleeve 22 is pushed against the return spring 25, and the other end of the spring stopper 23...

Abstract

The invention discloses a kind of pure water electromagnetic ball valve. It includes electromagnet, mechanism of force amplification, ball valve core in the hole of valve body, rest spring, valve cap and push bar. On the upper of valve body there is water inlet, water outlet and back water gap connected by channel; through leaving and covering of ceramic ball and valve seat, forming open and closed circuit to change the direction of fluid flow. The ceramic ball is generated by driving force of the dry-type DC electromagnet and spring force of the reset spring, and transmitted by the push bar. The proper layout of flow channel balance hydraulic pressure of the push bar and the ceramic ball. The invention achieves zero leakage by sealing directly valve plug and valve cover, valve cover and valve body, the core of ceramic ball and valve seat; improves static performance of the electromagnetic ball valve by add valve port dampers; switch fast by electromagnets with larger thrust and mechanism of force amplification. This valve is versatile and fit to work under conditions of middle and high pressure water medium.

Description

technical field [0001] The invention relates to valves, in particular to a pure water electromagnetic ball valve. Background technique [0002] Due to its unique advantages of environmental protection and flame retardancy, pure water hydraulic technology is being widely valued by hydraulic circles all over the world, and pure water hydraulic components have also become one of the key research contents. The reversing valve is one of the most critical valve components in the hydraulic system, and the research on the reversing valve suitable for the pure water hydraulic system has also become a research focus. [0003] Most of the traditional hydraulic directional valves are slide valve, rotary valve or cone valve. The unbalanced force on the spool of the slide valve type and rotary valve type reversing valve is very small, and the required operating force is also small, but there must be a gap for relative movement between the spool and the valve hole, and the leakage is ofte...
