Abstract
The invention relates to a fully sealed magnetic traction steam electric valve, which consists of two major parts: a valve body and a magnetic traction device and has the main advantages that a gap between a static valve body and a rotating valve shaft is sealed, the suction force of a magnet is utilized for opening and closing the valve in an inside and outside isolation state, and the efficacy of permanent leakage prevention between the valve shafts is realized.
Description
One, technical field
The present invention relates to a kind of valve, a kind of more precisely leakage-free valve that the gap closing of valve body and valve shaft is got up.
Two, background technique
Human application to valve has had the history of centuries, and the formed leakage in slit between static valve body and the valve shaft rotation still fails thoroughly to solve so far.Though the high-abrasive material that new and high technology is produced comes out again and again, the rotation wearing and tearing still can't solve the difficult problem of its leakage for a long time.Especially to the sealing of high temperature and high pressure steam,,, still belong to blank at present so need not to change, adjust the nonvolatil valve of seal ring because any material is not all broken away from the variation of expanding with heat and contract with cold.
Three, summary of the invention
In order to fill up above-mentioned blank, the object of the invention is to provide a kind of permanent leak free manufacturing new method.It is made and simply need not mould, realizes that lifelong sealing is easy to again.Concrete scheme is: utilize axle seam closed cylinder that it is closed in the slit of valve body and valve shaft, the magnet fuse is installed in closed cylinder is connected the valve body sealing head, outside the operation cylinder, inlay the magnet collar, operated up and down by the operation cylinder.That is to say under inside and outside isolated situation utilizes magnet suction to draw the Push And Release of sealing head.And between valve body and axle seam closed cylinder, install (2-1) axle seam closed cylinder conduit additional, and prolong the cool time of condensed water, guaranteed the permanent and flexibility of strong magnetic.
Four, description of drawings
Be enforcement structural drawing of the present invention in the legend:
See figure: (1) valve body (air outlet up during installation), (2) sealing head, (2-1) axle seam closed cylinder conduit; (3) axle seam closed cylinder, fuse in (4) magnet, (5) magnet outer sleeve (5-1) guide rail; (6) operation cylinder, (7) inner bearing, (8) square spiral shell axle; (9) Magnetic force tracting device outer cover, (10) outer bearing, (12) micromachine.
Five, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description
Operation: when (12) micromachine work, utilize (8) square thread, drive (6) operation cylinder, because (5-1) effect of guide rail makes (6) operation cylinder only can not rotate and can rise or descend.(5) go up or following operation thereupon the magnet outer sleeve periphery that is embedded in (6) operation cylinder, and interior (4) the magnet fuse of (3) axle seam closed cylinder is owing to operation is followed in the effect of suction, with (2) sealing head unlatching that links together simultaneously.When motor reverses with same principle with valve closing.
Claims (3)
1. a totally-enclosed Magnetic force tracting steam electric valve is characterized in that: utilize (3) axle seam closed cylinder to seal in the slit between the valve shaft of static valve body and rotation.
2. according to claim 1; It is characterized in that: (4) magnet fuse connects (2) sealing head of main body valve; (5) the magnet outer sleeve is embedded in the periphery of (6) operation cylinder, under inside and outside isolated state, draws the Push And Release of main body valve (2) by the operation up and down of (6) operation cylinder.
3. according to claim 1, it is characterized in that: between valve body and axle seam closed cylinder, install (2-1) axle seam closed cylinder conduit additional, prolong the cool time of condensed water, guaranteed the permanent of strong magnetic.
