Abstract
The utility model provides a magnetic valve, belonging to the improved design for a gate valve of a pipeline, which comprises a valve body and a valve plate. The utility model is characterized in that the valve body is fixedly connected with a distance sleeve, and the distance sleeve is fixedly connected with an indicator casing of the valve position. The inside of the distance sleeve is provided with a screw rod fixedly connected with the valve plate, and the screw rod is connected with a rotating nut. The rotating nut is fixedly connected with an inner rotor, and the inner rotor is fixedly connected with a permanent magnet of the inner rotor and is provided with an outer rotor which is supported on the outer diameter of the indicator casing. The inner diameter of the outer rotor is fixedly connected with a permanent magnet of the outer rotor, and the outer rotor is fixedly connected with hand wheels. The inside of the indicator casing of the valve position is provided with an inner permanent magnet stuck on an optical shaft of the screw rod, and the outline is provided with the outer permanent magnet in the form of slide.
Description
The magnet valve metal conduit that the utility model relates to designs with the improvement of gate valve.
Gate valve of the prior art adopts the direct contact type valve mostly, and promptly handle rotating band ovable valve stem rotates the unlatching that makes the upper and lower displacement realization of flashboard valve or closes.The defective of above-mentioned gate valve is under opening state, and liquid easily leaks outside along valve rod screw thread place; Direct contact type valve Yin Qiyi leaks and uses under as environment such as acid, alkali, toxic gas in some place and to be not suitable in addition.
The utility model purpose is to provide a kind of magnet valve design of non-direct contact type, to improve the airtight performance of direct contact type gate valve.
The technological scheme that adopts that achieves the above object is: this magnet valve, comprise valve body, and can open or the flashboard of valve body internal diameter passage, it is characterized in that: be fixed with separation sleeve on the valve body, be fixed with the valve position indicator shell on the separation sleeve; Be fixed with screw rod on the flashboard; To the spacing swivel nut that is connected with, the swivel nut external diameter is fixed with internal rotor, evenly is fixed with the internal rotor permanent-magnetic body of at least two alternate settings of polarity on the internal rotor external diameter by interior location annulate shaft in screw flight portion upper end; Have and be slidingly matched with valve position indicator shell external diameter and support external rotor on it, the external rotor internal diameter be fixed with internal rotor on the external rotor permanent magnet body of the corresponding setting of permanent magnet, the external rotor upper end is fixed with handwheel; The interior permanent magnet that has the optical axis shaft end that is slidingly matched with it and is connected in screw rod in the valve position indicator shell, on valve position indicator shell external frame, be slidingly matched be fitted with outside permanent magnet.
The utility model advantage is: owing to adopted the contactless kind of drive, component such as flashboard are worked in a closed chamber, so can avoid liquid or the gas phenomenon that leaks outside, have the advantage of good airproof performance.This magnet valve also has the valve position indicating device, and this device also is to have adopted the contactless kind of drive, can clearly show the flashboard position, has made things convenient for user's operation and use.
Fig. 1 is the organigram of this magnet valve.
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
The embodiment who provides below in conjunction with accompanying drawing further describes.Referring to accompanying drawing, this magnet valve includes valve body (1), be provided with the flashboard (2) that groove with it is slidingly matched in the valve body (1), be fixed with separation sleeve (3) on the valve body (1), separation sleeve (3) is gone up and is fixed with valve position indicator shell (4) by nut, flashboard (2) is gone up by its side channel structure and is fixed with screw rod (5), upper end, screw rod (5) screw section screw thread is connected with swivel nut (6), swivel nut (6) external diameter is fixed with one with internal rotor (7) by itself side structure, evenly is bonded with the internal rotor permanent-magnetic body (8) of four alternate settings of polarity on the external diameter of internal rotor (7).External rotor (9) is supported on the shaft shoulder place of valve position indicator shell (4) and the load that is slidingly matched with it, on external rotor (9) internal diameter bonding be fixed with internal rotor on four external rotor permanent magnet bodies (10) of the corresponding setting of permanent magnet (8), be provided with the gap between external rotor permanent magnet body (10) and the separation sleeve (3), external rotor (9) upper end also is fixed with handwheel (11) by the side's structure of itself.Has optical axis (12) structure on the screw rod (5), the bonding interior permanent magnet (13) that is slidingly matched with valve position indicator shell (4) internal diameter that is fixed with of the shaft end of optical axis (12), on valve position indicator shell (4) external frame, be slidingly matched be fitted with outside permanent magnet (14), on the valve position indicator shell, be carved with the delineation line of expression flashboard position.The interior positioning ring (15) that also has internal diameter stationary fit load with it in the end of separation sleeve (3) is used for nut (6) and internal rotor (7) axial limiting.At the quiet equipped outer positioning ring (16) that is connected with of the inner diameter end of external rotor (9).Above-mentioned part all can adopt white steel or copper material to make except that valve body (1) and permanent magnet and sealing gasket (17).
The working procedure of this magnet valve is: establish the closed condition that Figure 1 shows that valve, when rotating handwheel (11), external rotor (9) rotates relative to separation sleeve (3), outside under the magnetic force of rotor permanent magnet (10), internal rotor permanent-magnetic body (8) rotates together with internal rotor (7), and driven rotary nut (6) rotates around screw rod (5), can only do the original place because of swivel nut (6) is axially limited and rotate, so screw rod (5) swivel nut (6) relatively moves on top offset drive flashboard (2), magnet valve is the unlatching shape; Because of interior permanent magnet (13) with moving on the screw rod (5) and go up the moving outer permanent magnet (14) of shipper pole with on move, with reference to the delineation line of scribing on valve position indicator shell (4) external frame, can represent the opening degree of flashboard (2).When closing magnet valve, as long as change hands wheel (11) in the opposite direction till flashboard locking valve channel.
Claims (3)
