Problems solved by technology

Although wear-resistant materials produced by high-tech come out frequently, long-term rotating wear still cannot solve the problem of leakage
Especially for the sealing of high-temperature and high-pressure steam, because any material cannot get rid of the changes of thermal expansion and contraction, so there is no need to replace or adjust the permanent valve of the sealing ring, which is still blank at present

Embodiment Construction

[0006] The present invention will be described again below in conjunction with embodiment and accompanying drawing thereof

[0007] See figure: (1) and (2) comprise intake pipe, flange general name valve main body; (3) to (11) general name magnetic force tractor.

[0008] Operation: when (11) miniature motor works, utilize (8) square screw thread to drive (6) running cylinder, due to the effect of (5-1) guide rail, make (6) running cylinder not rotate but only rise or fall. (5) The outer ring of the magnet is embedded in the periphery of the (6) running cylinder and then runs up or down. At the same time (3) the shaft seam is closed and the (4) magnet core in the cylinder follows the operation due to the suction force, and will be connected together (2) The sealing head is opened, and the valve is closed by the same principle when the motor reverses.

Abstract

The invention discloses a full-closed magnetic force-pulled electrically operated valve which consists of two parts, i.e. a valve main body and a magnetic force tractor. The full-closed magnetic force-pulled electrically operated valve has main advantages that a gap between a static valve body and a rotating valve shaft is closed; and in a state that the inside is isolated from the outside, the valve is opened or closed by using an attractive force of a magnet, so that the efficacy that the leakage between every two valve shafts is permanently avoided is achieved.

Description

1. Technical field [0001] The invention relates to a valve, more precisely a non-leakage valve which seals the gap between the valve body and the valve shaft. 2. Background technology [0002] Human beings have been using valves for hundreds of years, and the leakage caused by the gap between the stationary valve body and the rotating valve shaft has not been completely solved so far. Although wear-resistant materials produced by high-tech come out frequently, long-term rotating wear still cannot solve the problem of leakage. Especially for the sealing of high-temperature and high-pressure steam, because any material cannot get rid of the changes of thermal expansion and contraction, there is no need to replace or adjust the permanent valve of the sealing ring, which is still blank at present. 3. Contents of the invention [0003] In order to fill the gap mentioned above, the purpose of the present invention is to provide a new permanent and leak-free manufacturing method...
