Abstract
The utility model relates to a pressure vessel valve, which comprises a new valve rod and an axle sleeve made of polytetrafluorethylene materials arranged on the new valve rod; a seal tray is arranged at the bottom of the new valve rod, a sharp side or a sharp surface adapted to form a seal matching with the bottom plane of the axle sleeve is provided an upper end surface of the seal tray. The pressure vessel valve of the utility model adopts the new valve rod and the axle sleeve to replace the valve rod, a retaining ring, a rubber seal washer, a seal washer made of abrasion resistance materials and a rotary connecting sheet in the prior art. According to the utility model, the seal tray of the new valve rod and the bottom plane of the axle sleeve compose a line seal matching, when the valve body rotates, the abrasion of the new valve body and the axle sleeve is more, the line seal effect therebetween is better. The seal effect of the utility model is better than the seal effect of the conventional O-shaped seal ring. Accordingly, the valve of the utility model has advantages of simple structure, good sealing performance, and long life service, and is not easy to leak caused by the abrasion.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of valve that is applied to liquefied petroleum ga steel cylinder, LNG Liquefied natural gas steel cylinder equal pressure container.
Background technique
See Fig. 1, China utility model patent ZL200820035957.X discloses a kind of cylinder for liquefied gas valve, comprise valve body 1, valve rod 2, sheet 3 is rotationally connected, spool 4, gland nut 5 and the handwheel 6 that is loaded on valve rod 2 upper end portions, the underpart of valve rod 2 is connected with spool 4 by the sheet 3 that is rotationally connected, on described valve rod 2, be provided with black box, between described valve body 1 and described valve rod 2, also be provided with back-up ring 7, this back-up ring 7 is sleeved on the valve rod 2, between the upper end portion 1-1 of this back-up ring 7 and valve body 1, be provided with seal washer 12, compress described back-up ring 7 by described gland nut 5, make this back-up ring 7 constitute linear sealing and cooperate with valve body 1; Also be provided with a convex shoulder 21 in the underpart of described valve rod 2, be provided with an annular groove of putting into jump ring 8 on described valve rod 2, described jump ring 8 application of force mouth pressures are clamped in described black box between described back-up ring 7 and the convex shoulder 2-1.Mark 9-1,9-2 among Fig. 1 and 12 is rubber gasket, and 10-1 and 10-2 are the high-abrasive material seal washer, and 11 is valve pad.
Above-mentioned the deficiencies in the prior art part is: the rubber gasket 9-1 of back-up ring 7 belows and 9-2 wear and tear easily and between high-abrasive material seal washer 10-1 and the 10-2, easily cause gas leakage after the use long period, thereby have influenced safe in utilization.
The model utility content
Technical problem to be solved in the utility model provides a kind of simple in structure, sealability better and be difficult for taking place because of the valves of pressure vessel that wearing and tearing are leaked gas, working life is long.
For solving the problems of the technologies described above, the utility model provides a kind of valves of pressure vessel, comprising: new valve rod and the axle sleeve that is placed in the polytetrafluoroethylmaterial material on the new valve rod; The bottom of new valve rod is provided with seal disc, and the upper-end surface of sealing dish has and is suitable for constituting sharp edge that linear sealing cooperates or sharp with the base plane of axle sleeve.
Further, the central authorities of described seal disc are provided with the cotter pilotage that is used to connect spool.
Further, the upper-end surface of described seal disc is a conical surface, the outward edge of this conical surface is to be suitable for constituting sharp edge that linear sealing cooperates or sharp with the base plane of axle sleeve, thereby when valve body rotates use, its sealing effect is much better than the sealing effect of traditional O RunddichtringO, and the wearing and tearing more of new valve body and axle sleeve, the effect of linear sealing therebetween is good more.
Further, for further improving the effect of linear sealing, the edge of the base plane of described axle sleeve has annular relief.
Further, belled position with described axle sleeve on the described new valve rod is shape with a tight waist, thereby when sleeve sealing is arranged at the top ports of valve body 1, under the pressure of gland nut 5, radial contraction takes place in the middle and upper part of axle sleeve, and forms drive fit with shape with a tight waist position on the new valve rod, has improved the firm degree that new valve rod is connected with axle sleeve, also improve the impacting force that described linear sealing cooperates, and then improved the sealing effect that linear sealing cooperates.
Further, the foundation ring of described belled position is provided with hangnail, prevents new valve rod and axle sleeve generation axial displacement.
Further, the cross section of described axle sleeve is the T font, and sleeve sealing is arranged at the top ports of valve body.
The utlity model has positive effect: new valve rod and axle sleeve that (1) valves of pressure vessel of the present utility model adopts, replaced the valve rod 2 in the prior art, back-up ring 7, rubber gasket 9-1 and 9-2, high-abrasive material seal washer 10-1 and 10-2 and the sheet 3 that is rotationally connected.In the valves of pressure vessel of the present utility model, the seal disc of new valve rod constitutes linear sealing with the base plane of axle sleeve and cooperates.When valve body rotates, the wearing and tearing more of new valve body and axle sleeve, the effect of linear sealing therebetween is good more.Its sealing effect is much better than the sealing effect of traditional O RunddichtringO, and therefore simple, the sealability of valve mechanism of the present utility model better and be difficult for taking place because of wearing and tearing are leaked gas, working life is longer.
