Description
Technical field
The utility model relates to a kind of elastic sealing structure, especially relates to a kind of elastic sealing structure of telescoping valve.
Background technique
At present, the sealing configuration of most of sleeve piston valve is hard extruding type, does not have pressure booster action, and the time has been grown sealing and easily squeezed rotten, reduces sealability, thus causes leaking, and steering force is large.
Chinese patent CN202451911U discloses a kind of Y type many spray orifice decompressions flow-adjustable valve, this flow-adjustable valve comprises valve body, valve gap, sleeve, valve rod and sliding sleeve lock, sleeve is arranged in the space that formed by valve body and valve gap, and multiple spray orifice is offered in bottom, sleeve inner is provided with the sliding sleeve lock be slidably connected with sleeve, valve rod one end is fixedly connected with sliding sleeve lock through valve gap, the lower cartridge of this flow-adjustable valve is by sealing seat and valve seal, structure due to sealing seat is unidirectional, in sleeve inner as effective during water intake, and when sleeve outside is as water intake, when pressure is higher, seal ring can be blown, sealing effect is bad, fragile, easy leakage.
Model utility content
The purpose of this utility model is exactly provide the elastic sealing structure of the telescoping valve that a kind of good sealing effect, steering force are little, the life-span is long, not fragile, applicability is wide to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of elastic sealing structure of telescoping valve, for the sealing between the sleeve of telescoping valve and valve body, described sleeve lower end is connected with protruding circle, inside is provided with lock cylinder, described lock cylinder bottom is provided with sealing surface, and the angle a of sealing face and vertical line is 25-35 degree, and the inside grooves of valve body is provided with elastic sealing structure, described projection circle and the groove shapes of elastic sealing structure are harmonious, and described elastic sealing structure comprises U-shaped sealed body and seal angle integrated with U-shaped sealed body.
The cross section of described seal angle is triangle, this leg-of-mutton base and U-shaped sealed body one-body molded, the angle b of limit, left side and vertical line 2-3 degree larger than the angle a of sealing surface and vertical line, the angle c of right edge and vertical line is 10-20 degree.
The left surface area of described seal angle is less than the area of right flank.
Described U-shaped sealed body is provided with groove circle with the protruding surface of contact enclosed, and described groove circle is provided with at least one circle tooth.
The described bottom of U-shaped sealed body and the surface of contact of valve body recess are provided with O RunddichtringO.
Described elastic sealing structure adopts rubber, nylon or high density PE to make.
Compared with prior art, the utility model has the following advantages:
One, good sealing effect, steering force are little: when lock cylinder moves downward throttle down, the sealing surface of lock cylinder lower end and the left surface lower contacts of seal angle form linear sealing, at this moment the gap of 2-3 degree is also had between left surface and sealing surface, area due to seal angle left surface is less than the area of right flank, so the pressure be subject to is less than right flank, cause seal angle to compress under the effect of the pressure left, make left surface and the sealing of sealing surface forming surface, only need very little steering force, just can accomplish zero leakage.
Two, the life-span is long, not fragile: because sealing seat is not the method sealing of enforced extrusion type, therefore not fragile sealing seat, working life increases greatly.
Three, applicability is wide: elastic sealing structure of the present utility model can adapt to the telescoping valve of the overwhelming majority, comprises the telescoping valve such as Y type flow-adjustable valve and right angle flow-adjustable valve.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1:
As Figure 1-3, a kind of elastic sealing structure of telescoping valve, for the sealing between the sleeve 2 of telescoping valve and valve body 1, sleeve 2 lower end is connected with protruding circle 7, and the inside of sleeve 2 is provided with lock cylinder 3, and lock cylinder 3 bottom is provided with sealing surface, and the angle a of sealing face and vertical line is 25 degree, the inside grooves of valve body 1 is provided with elastic sealing structure 4, and protruding circle 7 is harmonious with the groove shapes of elastic sealing structure 4, and elastic sealing structure 4 comprises U-shaped sealed body and seal angle integrated with U-shaped sealed body.
The cross section of seal angle is triangle, this leg-of-mutton base and U-shaped sealed body one-body molded, the angle b of left side limit and vertical line is than large 2 degree of the angle a of sealing surface and vertical line, the angle c of right edge and vertical line is 10 degree, the left surface area of seal angle is less than the area of right flank, the surface of contact that U-shaped sealed body encloses 7 with projection is provided with groove circle 6, groove circle 6 is provided with at least one circle tooth, the bottom of U-shaped sealed body and the surface of contact of valve body 1 groove are provided with O RunddichtringO 5, and elastic sealing structure adopts rubber, nylon or high density PE to make.
Embodiment 2:
A kind of elastic sealing structure of telescoping valve, the sealing surface of lock cylinder 3 bottom and the angle a of vertical line are 30 degree, the limit, left side of seal angle and the angle b of vertical line are than large 2 degree of the angle a of sealing surface and vertical line, and the angle c of right edge and vertical line is 15 degree, and remaining part is all identical with embodiment 1.
Embodiment 3:
A kind of elastic sealing structure of telescoping valve, the sealing surface of lock cylinder 3 bottom and the angle a of vertical line are 35 degree, the limit, left side of seal angle and the angle b of vertical line are than large 3 degree of the angle a of sealing surface and vertical line, and the angle c of right edge and vertical line is 20 degree, and remaining part is all identical with embodiment 1.
When lock cylinder moves downward throttle down, the sealing surface of lock cylinder lower end and the left surface lower contacts of seal angle form linear sealing, at this moment the gap of 2-3 degree is also had between left surface and sealing surface, area due to seal angle left surface is less than the area of right flank, so the pressure be subject to is less than right flank, seal angle is caused to compress under the effect of the pressure left, make left surface and the sealing of sealing surface forming surface, now medium is to diffluence in the gap of the right flank of elastic sealing structure 4 seal angle, but be subject to groove circle 6 to intercept, medium is had nowhere to go, force right flank to squeeze towards sealing surface direction to go, enhance the sealing surface of seal angle left surface and lock cylinder 3 in conjunction with effect, make sealing tightr, the medium of groove circle 6 another side also cannot by the surface of contact of protruding circle 7 simultaneously, medium can not leak, valve body 1 is then blocked by O RunddichtringO 5 with the surface of contact of elastic sealing structure 4, medium also can not leak, save steering force, and can zero leakage be accomplished.
