Abstract

The utility model discloses a fully sealed magnetic coupling stop valve. In the utility model, for the opening and the closure of the fully sealed magnetic coupling stop valve, with the adoption a spiral pair composed of a starting shaft and an outer magnetic steel sleeve, the torsional moment at the time of opening can be larger than the torsional moment at the time of closure; a magnetic coupling device forms a fully sealed structure; so the problem of the leakage of the fully sealed magnetic coupling stop valve can be fundamentally solved; an axial thrust ball bearing is arranged between a hand wheel and the starting shaft; the resistance in opening and closing the fully sealed magnetic coupling stop valve is little; after the inside of the fully sealed magnetic coupling stop valve is provided with a fluoroplastic lining, a fully sealed valve with a fluoroplastic lining can be formed; thus, the valve with the magnetic coupling device is a breakthrough and a create in the structural design of the valve. The utility model can be widely installed on pipelines of high temperature and high pressure, inflammable and explosive, valued, toxic, corrosive medium.

Description

Hermetically sealed Magnetic Cooperate Globe Valves
The utility model relates to a kind of hermetically sealed Magnetic Cooperate Globe Valves.
Known stop valve, no matter be hand stop valve or Electric Actuated Stop Valves, structurally all have valve body, flap, valve rod, seal arrangement and starting drive, wherein seal arrangement adopts packing seal at present, during using, this packing seal has two problems: the one, after the filler wearing and tearing, the dielectric leakage phenomenon is inevitable, and the 2nd, filler need compress, and causes the resistance of this valve big.
The purpose of this utility model provides the hermetically sealed nothing of a kind of medium and leaks, and opens and closes the little stop valve of resistance.
Solving main points of the present utility model is that described seal arrangement adopts the magnetic drives magnetic coupling device; Starting drive is that startup axle and the connection of outer steel cover are one group of screw pairs, inside and outside magnet steel magnetic coupling useful area when inside and outside magnet steel magnetic coupling useful area is greater than valve closing when making valve opening has been installed axial ball bearing between handwheel (Electric Actuated Stop Valves is a gear) and the startup axle simultaneously.
Below in conjunction with accompanying drawing, content of the present utility model is described in further detail.
The structural drawing when hand stop valve that Fig. 1 has a magnetic coupling device opens.
The structural drawing when hand stop valve that Fig. 2 has a magnetic coupling device cuts out.
Fig. 3 has the Electric Actuated Stop Valves structural drawing of magnetic coupling device.
As shown in the figure, this have magnetic-coupled stop valve valve body (1), flap (2), valve rod (3), magnetic coupling device and starting drive arranged.The starting drive of hand stop valve is made up of handwheel (11) and startup axle (9), and the starting drive of Electric Actuated Stop Valves is made up of motor (19), retarder (18), gear (17) and startup axle (9).Magnetic coupling device is by outer steel (7), interior magnet steel (5), separation sleeve (4) and hitch 12, assemble, separation sleeve (4) is separated into outer steel chamber (13) and interior magnet steel chamber (14) with the magnet steel chamber, outer steel (7) places outer steel chamber (13), and by outer steel cover (8) and startup axle (9) connection, for valve is opened, it is normal to close operation, outer steel (7) structural design on the energy, following shifter, promptly magnetic steel sleeve (8) is provided with internal thread outside, start and establish outside thread formation screw pair on the axle (9), in when making valve opening magnet steel (5) and the magnetic-coupled effective magnetic surface of outer steel (7) long-pending (as Fig. 1) when closing in magnet steel (5) and the magnetic-coupled effective magnetic surface of outer steel (7) amass (as Fig. 2), reach when opening torque force torque force when closing, thereby valve is opened and closed smoothly.
Interior magnet steel (5) places interior magnet steel chamber (14), and is inlaid on the interior magnet steel seat (6), and interior magnet steel seat (6) is provided with inner bolt hole, and the outside thread on the same valve rod (3) forms screw pair.Valve rod (3) only pumps, and does not rotate, and for this reason, valve rod (3) is set the axial displacement guide mechanism, is made of the square shaft (16) on the same valve rod of square cover (15) (3).
Carry Korrosionsmedium with this stop valve with magnetic coupling device, in valve body (1), interior magnet steel chamber (14), have the steel member that contacts can select for use stainless steel to make with medium, also can be at the internal surface of valve body (1) and in placing the component surface in the magnet steel chamber (14) establish the fluoroplastics lining nexine.
For Electric Actuated Stop Valves, motor (19) should have can be according to the control circuit of the automatic stall in upper and lower dead center position of flap (2).
The keying of above-mentioned stop valve is that the magnetic drives by inside and outside magnet steel realizes, magnetic coupling device forms hermetic valve mechanism, the motive sealing that becomes known valve is static seal, make this valve not have the leakage problem of medium, thoroughly solved the difficult problem that there are run, drip, leak in valve, the time coexist handwheel (11) (Electric Actuated Stop Valves is gear (17)) and start that device has axial ball bearing between the axle (9), obvious, the keying resistance of this valve is smaller.Therefore, this valve is more suitable for being installed on the pipeline of carrying media such as High Temperature High Pressure, inflammable and explosive, valuable, poisonous, corrosivity and uses.Behind the inner lining fluoroplastics lining, become again a kind of can better stop valve than stainless steel stop valve corrosion resistance, this shows to have the stop valve of magnetic coupling device, be important breakthrough and creation in the stop valve structure design.

Claims (2)

1, a kind of hermetically sealed Magnetic Cooperate Globe Valves is by valve body, flap, valve rod, magnetic drives full-sealing device and starting drive constitute, the magnetic drives magnetic coupling device is assembled by outer steel, interior magnet steel, separation sleeve and hitch, the starting drive of manually-operated gate is made up of handwheel and startup axle, the starting drive of electric valve is made up of motor, retarder, gear pair and startup axle, it is characterized in that: the described connecting structure that starts axle and outer steel cover is one group of screw pair.
2, according to right 1 described hermetically sealed Magnetic Cooperate Globe Valves, it is characterized in that; Start between axle and the handwheel and installed axial ball bearing, electric valve is to start between axle and the gear to have installed axial ball bearing.
