Description
Technical field
This utility model relates to the sealing device of a kind of combined high-voltage pressure regulator valve.
Background technology
The key technology of pressure regulator valve is the sealing problem of water cavity valve seat and steel ball, owing to the circularity precision of steel ball is extremely difficult to, particularly conveying corrosive liquid, steel ball must adopt stainless steel material, its precision is more difficult to ensure, therefore steel ball and the sealing of water cavity valve seat very difficult solution always. If water cavity valve seat adopts metal material to make, the seepage owing to the out-of-roundness of steel ball can cause steel ball and water cavity valve base sealing bad; If water cavity seat material adopts plastic production, although the out-of-roundness of steel ball is less on the impact of its sealing property, but in operation, when commutation handle pulls commutation valve rod rotary dial steel ball, owing to water cavity valve seat by steel ball tight note under 50bar hydraulic pressure, commutation valve rod need to be stirred steel ball from the side by bigger power when rotating and just can open, and now the aperture of water cavity valve seat can be produced extruding and deform by steel ball, thus affecting the sealing effectiveness of steel ball and water cavity valve seat and producing seepage; According to installing elastic seal ring at water cavity valve seat aperture place, when steel ball is opened, owing to sealing ring can lose efficacy from steel ball side extrusion under the effect of High-Pressure Water.
Summary of the invention
The sealing effectiveness that the purpose of this utility model is for solving between water cavity valve seat and the steel ball of current pressure regulator valve is poor, it is easy to the technical problem of seepage.
In order to solve above-mentioned technical barrier, this utility model provides the sealing device of a kind of combined high-voltage pressure regulator valve, including water cavity valve seat and steel ball, described water cavity valve seat includes base metal part, being provided with a circle groove with described steel ball on the end face contacted on described base metal part, the metalwork between described groove with described water cavity valve base inner wall contacts with described steel ball; Described groove is injected with elastomer.
Further, described base metal part sidewall is additionally provided with an annular groove, in described annular groove, is injected with elastomer.
Further, described annular groove offers 4 apertures connected with described groove, described aperture is all injected with elastomer.
Further, described base metal part sidewall is additionally provided with a circle seal groove, in described seal groove, is provided with sealing ring.
First this utility model arranges a circle groove on water cavity valve seat end face, and the metalwork of groove inner ring is in order to support the highly pressurised liquid pressure to steel ball so that it is the elastomer in valve seat aperture will not be caused crimp in a high voltage state. Shooting Technique is adopted to inject elastomer with steel ball sealing position in groove, in order to make the elastomer of injection do not extruded by highly pressurised liquid, sidewall at water cavity valve seat processes an annular groove near the periphery injecting elastomer, in annular groove, it is drilled with 4 apertures be connected with groove, elastomeric material fills during injection moulding annular groove be connected with the elastomer in the groove of Kong Bingyu aperture so that the elastomer in water cavity valve seat aperture is difficult to be extruded by highly pressurised liquid. When water cavity valve seat fitted in a high voltage state by steel ball, water cavity valve seat metalwork suitable for reading supports the steel ball under high pressure effect, the elastomer in water cavity valve seat aperture only plays sealing function, when the valve rod that commutates stirs steel ball, steel ball only to the elastomer in water cavity valve seat aperture in elastic range internal strain, once after steel ball leaves, the elastomer in water cavity valve seat aperture recovers again original state, thus playing sealing function all the time. After adopting this structure, the required precision of steel ball is substantially reduced, and seals reliable, long service life.
