Abstract
The invention provides a dual sealing high pressure grease filling valve. The upper part of a valve tip is provided with a movable hard sealing ball; the movable hard sealing ball and a grease filling hole in an internal cavity of the valve body generate a ball-shaped linear sealing; the taper of the valve tip is provide with an elastic sealing ring which is hermetically contacted with the taper in the grease filling hole of the internal cavity of the valve body; the movable hard sealing ball and the grease filing hole in the internal cavity of the valve body generate the linear sealing closing and generate a sealing line; another sealing line is generated by the contact between the taper in the grease filling hole of the valve body and the rebounded elastic sealing ring on the taper of the valve tip. In the sealing structure of the invention, the interior of the valve body adopts the dual sealing between the movable hard sealing ball and the taper elastic sealing ring; when the sealing abrasion appears to the abrasion, the valve body bevel and the elastic sealing ring can take a compensation function, thus reaching the aim of preventing the medium leakage, and having good sealing performance and long service life, etc.
Description
Technical field
The present invention relates to a kind of high-pressure grease pouring valve, relate in particular to a kind of double sealings high-pressure grease pouring valve.
Background technique
At present, the grease pouring valve of domestic production is the sealing of single sealing hard sphere, the material that it is selected for use, comprise the operating conditions that does not satisfy sealing life at high pressure or rugged environment, produced the phenomenon of " run, leak " grease, do not have the lubrication of grease to whole valve, the valve use to integral body has produced very big negative influence.
Summary of the invention
For overcoming the defective of existing high-pressure grease pouring valve, the invention provides a kind of double sealings high-pressure grease pouring valve.This double sealings high-pressure grease pouring valve can finely solve whole valve lubrication system and " run, leaked " problem.
The technology used in the present invention solution is: a kind of double sealings high-pressure grease pouring valve, comprise valve body, valve point, the valve point places body cavity, valve point top is provided with movable hard seal ball, the greasing hole of movable hard seal ball and body cavity produces the spherical line sealing, the conical surface of valve point is provided with elastic seal ring, the conical surface contact seal in the greasing hole of elastic seal ring and body cavity.Close with the greasing hole generation linear sealing of body cavity by movable hard seal ball, produce potted line one; Rebound to contact by the elastic seal ring on the feather valve pointed cone degree face and produce another road potted line with the conical surface in the valve body greasing hole.
Because in the above-mentioned sealing configuration, double seal at the inside of valve body employing activity hard seal ball and conical surface elastic seal ring, when wearing and tearing appear in sealing, but valve body inclined-plane and elastic seal ring redeeming, to reach the purpose that prevents dielectric leakage, has good seal performance, beneficial effects such as long service life.Be applicable to oil, chemical industry, pipeline upper ball valve, plate valve main accessories lubrication system grease pouring valve.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is the overall structure schematic representation of an embodiment of the present invention.
Among the figure: 1, valve body, 2, hard seal ball, 3, elastic seal ring, 4, the valve point, 5-1, first spring, 5-1, second spring, 6, the O RunddichtringO, 7, cotter pin, 8, the greasing hole.
Embodiment
Embodiment as shown in drawings, double sealings high-pressure grease pouring valve of the present invention comprises valve body 1, valve point 4, valve point 4 places valve body 1 inner chamber, is bearing on the valve body (1) by first spring (5-1); Valve point 4 tops are provided with movable hard seal ball 2, and hard seal ball 2 is bearing in valve point top by the second spring 5-2, and movable hard seal ball 2 produces the spherical line sealing with the greasing hole 8 of body cavity, and hard seal ball 2 can adopt steel ball; The conical surface of valve point 4 is provided with elastic seal ring 3, the conical surface contact seal in the greasing hole 8 of elastic seal ring 3 and body cavity, and elastic seal ring 3 is preferably the fluororubber O-type seal ring, to adapt to rugged environment work.High pressure injects grease, utilizes and enters grease system counter-flow media return pressure and spring force, and fluororubber O-type seal ring on its valve sharp conical surface contact with the conical surface on the valve body, and generation seals.Simultaneously, steel ball also is subjected to same elastic force and contacts the linear sealing of generation metal to metal with valve body greasing hole line.Present embodiment also increases O RunddichtringO 6 one at the external diameter of valve body 1 front end, with further raising sealability.
