Abstract
The invention relates to the internal power magnetic driving valve, which comprises the valve, the valve core, the valve rod and the magnetic couple device. It is characterized in that the decelerating driving device is between the output shaft of the said couple device and the valve rod, the output shaft of the magnetic couple device connects the input of the decelerating driving device, and the output end of the driving device connects with the valve rod. Because the decelerating driving device is between the output shaft of the couple device and the valve rod, so the torsion force of the magnetic driving is amplified by the build-in decelerating device to solve the problem of using small magnetic driving torsion to operate big torsion.
Description
Technical field
The present invention relates to a kind of valve, particularly the magneto drive valve.
Background technique
The leakage of valve mainly is divided into and leaks outside and interior leakage, and the topmost leakage point that leaks outside is exactly the sealing of valve rod and valve body.All the time, structures such as packing seal, sylphon seal are adopted in the sealing between valve valve gap and the valve rod.Then can only rely on packing seal to prevent to leak outside for pivoted lever class valve such as ball valve, butterfly valve.Though lifting bar class valve such as stop valve, gate valve etc. can adopt packing seal and sylphon seal simultaneously, sealing and unreliable when middle and high pressure.So adopt the magneto drive form to replace the thorough external leakage that solves the valve rod place of stem packing sealing active operation significance is arranged.Utilize " permanent magnetism contactless transmission " principle, by push-and-pull magnetic circuit optimal design, the switching motion of conventional valves is changed into the operation of permanent magnetism torsion, the packing seal at cancellation valve rod place, valve opening and closing mechanism shields fully in inside, really reach " zero leak outside " purpose, be specially adapted to medium and be in inflammable, explosive, the poisonous high pressure line.For this reason, be 89215301.6 and in " valve " patent of invention of bulletin on March 21 nineteen ninety, disclose a kind of valve in the patent No., this valve has the magnetic coupling device of being made up of outer steel, interior magnet steel, separation sleeve and hitch, the startup of valve realizes by the magnetic drives of inside and outside magnet steel, magnetic coupling device makes valve form all-sealed structure, fundamentally solve the dielectric leakage problem, behind the inner lining fluoroplastics lining, become totally-enclosed anticorrosion valve again.But because interior magnet steel rotor in this scheme and valve rod are to take the mode that directly is in transmission connection, this structure internally, between the outer steel rotor requirement of magnetic coupling force quite high, design and selection all have big difficulty, and problem will be more outstanding when using in pivoted lever class high pulling torque operated valves such as ball valve, butterfly valve.
Summary of the invention
The objective of the invention is to provides a kind of all kinds of valves that are suitable for for overcoming the deficiencies in the prior art, can realize utilizing less magnetic drives moment of torsion to solve the magneto drive valve of high pulling torque operational issue.
The invention has the beneficial effects as follows owing between the output shaft of magnetic force coupling device and valve rod, be provided with reduction gearing mechanism, the magnetic drives moment of torsion can amplify at double through built-in reducing gear, thereby can realize utilizing less magnetic drives moment of torsion to solve the problem of high pulling torque operation, effectively utilize magnetic energy.
The invention will be further described below in conjunction with the drawings and specific embodiments.
