Description

Magnetic drive Non-leakage valve
Technical field
The utility model relates to a kind of Magnetic drive Non-leakage valve.
Background technique
The rock gas of China was produced on the occasion of fast-developing period, and application area constantly expands, and oil refinery, chemical plant are also in continuous enlarging, and the pipeline of its conveying gas, liquid needs a large amount of various valve.Particularly mostly above-mentioned industry is to carry inflammable, explosive or poisonous gas, liquid, needs valve absolute ne-leakage guarantee safety.For conventional valves, between valve rod and the filler being arranged in valve gap, easily produce media leaks, therefore can bring very large harm to safety in production.
Model utility content
For solving the problems of the technologies described above, the utility model discloses a kind of Magnetic drive Non-leakage valve, its structure is simple, switch is flexible, long service life, good airproof performance, for the safety in production of enterprise provides guarantee.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of Magnetic drive Non-leakage valve, comprise valve body, described valve body is in aggregates by each flange closure in its two ends; Be provided with valve seat in described valve body, the side of described valve seat is followed successively by flap and is arranged with the valve rod of valve stem casing, and the front end of described valve rod is provided with body resistance-strengthening tablets, and rear end is provided with annular inner magnet; The periphery of described valve body is also provided with the outer magnet coordinated with above-mentioned inner magnet, and described outer magnet is fixedly connected with a handwheel; Described flap is provided with oil leak hole, and described valve seat is provided with medium through hole.
The utility model discloses a kind of Magnetic drive Non-leakage valve, its structure is simple, switch is flexible, long service life, good airproof performance, for the safety in production of enterprise provides guarantee.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the sectional view of Magnetic drive Non-leakage valve provided by the utility model.
Numeral in figure:
1, flange 2, body resistance-strengthening tablets 3, valve stem casing 4, valve rod 5, inner magnet 6, outer magnet
7, flap 8, oil leak hole 9, valve body 10, medium through hole 11, valve seat
12, handwheel.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
Shown in Fig. 1, a kind of Magnetic drive Non-leakage valve, comprises valve body 9, and described valve body 9 is closed in aggregates by each flange 1 in its two ends; Be provided with valve seat 11 in described valve body 9, the side of described valve seat 11 is followed successively by flap 7 and is arranged with the valve rod 4 of valve stem casing 3, and the front end of described valve rod 4 is provided with body resistance-strengthening tablets 2, and rear end is provided with annular inner magnet 5; The periphery of described valve body 9 is also provided with the outer magnet 6 coordinated with above-mentioned inner magnet 5, and described outer magnet 6 is fixedly connected with a handwheel 12; Handwheel 12 and outer magnet 6 are all located at the outside of valve body 9, rotate handwheel 12, outer magnet 6 can move axially along valve body 9, thus drives inner magnet 5 and valve rod 4 to move axially, make conventional valve rod 4 rotating manner become axial horizontal motion mode, reduce the wearing and tearing of surface of contact; Owing to being closed inside and outside valve body 9, therefore, the situation may stopping seepage occurs; Described flap 7 is provided with oil leak hole 8, and described valve seat 11 is provided with medium through hole 10.
The valve body of the valve that the utility model proposes is a complete seal, and wherein Sealing does not produce wearing and tearing substantially, therefore long service life and ne-leakage, for safety in production provides Reliable guarantee.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.
