Abstract
The utility model provides a soft seal ball valve, includes the valve body, installs the spheroid in the valve body, both ends in the valve body install with ball sealing complex disk seat, be sliding fit between disk seat and the valve body, install the spring holder between valve body and the disk seat, the inner horizontal direction roof pressure of spring holder is on the disk seat, the spring of roof pressure on the valve body is installed to the outer end of spring holder. Make like this for the spring contacts between disk seat and the spheroid, leakproofness good between disk seat and the spheroid is also guaranteed simultaneously to better protection disk seat and spheroid.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of soft sealing ball valve.
Background technique
Current ball valve in use, because the spheroid in valve body is when rotating, often produces sliding friction with valve seat, and produces hard collision, easily like this makes valve seat damage, matching loose between valve seat and valve body, and generation leakage.
Model utility content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of soft sealing ball valve, good airproof performance, long service life.
The utility model solves the technological scheme that its technical problem adopts: this soft sealing ball valve, comprise valve body, the spheroid be arranged in valve body, two ends in valve body are provided with the valve seat coordinated with ball seal, for being slidably matched between valve seat and valve body, between valve body and valve seat, spring seat is installed, the inner substantially horizontal top of spring seat is pressed on valve seat, and the outer end of spring seat is provided with the spring pushing up and be pressed on valve body.Make like this to be spring contact between valve seat and spheroid, better protection valve seat and spheroid, also ensures sealing good between valve seat and spheroid simultaneously.
In order to perfect further, valve seat outer wall has groove, spring seat is provided with the jacking block penetrated in groove, is provided with fire-resistant packing ring between jacking block and groove.Refractory block encloses good sealability, also has good fire performance simultaneously, prevents friction between packing ring and valve interior wall from producing flame.
Perfect further, the interior edge face of groove is ramp structure, and the interior edge face of fire-resistant packing ring is the ramp structure be mated.Fire-resistant like this packing ring and valve seat are when horizontally slipping, and by the effect of ramp structure, fire-resistant packing ring promotes by valve seat laterally, make fire-resistant packing ring and valve body close contact, ensure good sealing.
Perfect further, be provided with seal ring between valve seat outer wall and valve body.Make, between valve seat and valve body, there is better sealing like this.
Perfect further, valve seat interior edge face is provided with edge circle.Edge circle adopts high strength, high wear resistance material, at long-term and sphere structure, not yielding, ensures good sealing property.
Perfect further, have trough with straight angle in valve seat, the two ends of trough with straight angle are communicated with valve seat the inner and valve seat outer wall respectively.
The effect that the utility model is useful is: the utility model reasonable in design, and make valve body, have good sealing between valve seat and spheroid, long service life, wear resistance is high, is conducive to extensive popularization.

Description of reference numerals: valve body 1, spheroid 2, valve seat 3, groove 3-1, spring seat 4, jacking block 4-1, spring 5, fire-resistant packing ring 6, seal ring 7, edge circle 8, trough with straight angle 9.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: soft sealing ball valve in the present embodiment, comprise valve body 1, the spheroid 2 be arranged in valve body 1, two ends in valve body 2 are provided with the valve seat 3 be sealed and matched with spheroid 2, for being slidably matched between valve seat 3 and valve body 1, spring seat 4 is installed between valve body 1 and valve seat 3, the inner substantially horizontal top of spring seat 4 is pressed on valve seat 3, and the outer end of spring seat 4 is provided with the spring 5 pushing up and be pressed on valve body 2.
Wherein valve seat 3 outer wall has groove 3-1, spring seat 4 is provided with the jacking block 4-1 penetrated in groove 3-1, is provided with fire-resistant packing ring 6 between jacking block 4-1 and groove 3-1.The interior edge face of groove 3-1 is ramp structure, and the interior edge face of fire-resistant packing ring 6 is the ramp structure be mated.
Wherein be provided with seal ring 7 between valve seat 3 outer wall and valve body 1.Valve seat 3 interior edge face is provided with edge circle 8.Have trough with straight angle 9 in valve seat 3, the two ends of trough with straight angle 9 are communicated with valve seat 3 the inner and valve seat 3 outer wall respectively.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
