Description
Technical field
The utility model relates to a kind of adjusting, sealing of manual tune stop valve, particularly hand stop valve and opens size state and shows.
Background technique
At industry multipurpose small stainless steel hand stop valves such as oil, chemical industry, food, medicine, nuclear powers, between the screw rod of existing hand stop valve and valve gap, be threaded connection, screw rod borrows screw thread in valve gap, rotate and move up and down, and realizes the opening and closing of stop valve.In order to prevent that medium from flowing out from gap, in valve gap, place filler chamber, in filler chamber, fill up whippy soft-filler, screw rod is rotated in valve gap and do not leak, between the screw rod of this stop valve and valve gap, sealing configuration is movable sealing structure, in the occasion of often opening and closing, use, poor reliability, is difficult to ensure zero leakage.And for Leakage prevention, filler must be pressed very tightly, very effort of screw rod rotation like this.Occurred afterwards sealing type stop valve, valve rod is divided into 2 joints, and in the middle of valve rod, increased elastic caoutchouc seal dissepiment, the periphery of barrier film is pressed on valve body with valve gap, can prevent the dielectric leakage in valve.Although diaphragm of rubber good springiness, good seal performance, this can not use the occasion of High Temperature High Pressure.
Model utility content
The utility model is for the deficiency of above-mentioned technology, propose a kind of seal reliable, Torque-adjusting is little, the manual tune stop valve of opening big or small direct display, be specially adapted to high temperature, high pressure, corrosion resistant, requirement can intuitively show opens size, and requires the occasion of zero leakage.
The utility model is achieved through the following technical solutions:
A kind of manual tune stop valve, comprises valve body, spool, screw rod, seal closure, magnet-wheel and spinning roller; In valve body, be provided with valve seat, spool is set on valve seat; One end cavity of screw rod is embedded in spool, and the screw rod the other end is connected with magnet-wheel after passing valve body, and external thread of screw is connected with valve body screw-internal thread fit; Described valve seat and spool bottom coordinates for conical surface seal; Rotate by screw rod, Tapes movable valve plug is upper and lower, realize valve unlatching, close and Flow-rate adjustment.
The wheel body of described magnet-wheel be embedded with magnet steel all around.
Seal closure is installed in described valve body top, and seal closure is connected with valve body by flange, realizes static seal, in seal closure is sealed in screw rod, magnet-wheel.
In described seal closure top axle, spinning roller is installed, spinning roller top arranges axle sleeve, axle sleeve is fixed in seal closure top axle by nut, axle sleeve outside thread is connected with spinning roller screw-internal thread fit, spinning roller lower inside surface is embedded with magnet steel all around, while regulating spinning roller, magnetic coupling power is rotated magnet-wheel in seal closure simultaneously, and the moving screw rod rotating regulation valve door of Tapes is opened.
Described seal closure outer side surface and spinning roller lower edge are carved with respectively axial and circumferential scale, and scale indicating value instruction handwheel mobile position, can intuitively show valve opening size.
Compared with prior art, the utlity model has following characteristics:
1. the packing seal of screw rod is changed over seal closure sealing by the utility model, changes over static seal structure by movable sealing structure, and sealing is reliable, and long service life, can realize zero leakage.
Valve cancel stuffing box packing, can all adopt metallic material, be difficult for aging, resistance to irradiation, long service life.
3. valve is cancelled the stuffing box packing compressing, and screw rod rotation easily, is opened very laborsaving.
4. seal closure outer side surface and spinning roller lower edge are carved with respectively axial and circumferential scale, and scale indicating value instruction spinning roller mobile position, can intuitively show valve opening size, and this uses more convenient and practical to the occasion that has Flow-rate adjustment requirement.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model manual tune stop valve.
In figure: 1, valve body; 2, spool; 3, screw rod; 4, pressure pad; 5, magnet-wheel; 6, magnet steel I; 7, magnet steel II; 8, seal closure; 9, spinning roller; 10, nut; 11, the circumferential scale of spinning roller; 12, the axial scale of seal closure.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
In the valve body of the utility model manual tune stop valve, there is valve seat, in screw on valve body 1, be installed with the screw rod 3 matching with screw internal thread, one end cavity of screw rod is embedded in spool 2, the screw rod the other end is connected with magnet-wheel 5 after passing valve body, and screw rod is connected with valve body screw-internal thread fit, magnet-wheel body is embedded with magnet steel 6 around.Seal closure 8 is installed in valve body top, and seal closure is connected with valve body by pressure pad 4, and seal closure is realized static seal in screw rod, magnet-wheel are sealed in.
Spinning roller 9 is installed in seal closure top axle.The built-in axle sleeve in spinning roller top, axle sleeve and seal closure top axle are fixing by nut 10, and axle sleeve outside thread is connected with spinning roller screw-internal thread fit, spinning roller lower inner surface is embedded with magnet steel 7 around, while regulating spinning roller rotation, magnetic coupling interaction power is rotated magnet-wheel simultaneously, and Tapes ovable valve stem rotating regulation valve door is opened.Spinning roller lower edge is carved with circumferential scale 11, and seal closure outer side surface is carved with axial scale 12, and scale indicating value instruction handwheel mobile position, can intuitively show and open size.
The utility model is realized two resealings, the first resealing: spool and valve seat have adopted traditional conical surface sealing structure, and reliability is high; In the time that needs are communicated with, regulate spinning roller rotation, magnetic coupling interaction rotates magnet-wheel simultaneously, on the moving screw rod of Tapes, carries and makes spool to top offset, and valve seat taper hole is opened gradually, realizes and being communicated with; In the time closing, counterrotating, spool moves downward, and flow reduces gradually until close; The second resealing: the seal closure isolating seal that this is core, because being that static seal is safe and reliable, can guarantee, without leaking, to be adapted to very much high temperature, high pressure, corrosion protection, radiation proof and to require zero leakage occasion.
