The model utility content
The purpose of this utility model aims to provide a kind of cooling stop valve of simple and reasonable, good seal performance, to overcome deficiency of the prior art.
A kind of cooling stop valve by this purpose design, comprise the valve rod that is arranged in the valve body, valve pocket and seal ring are set in respectively on the valve rod, are provided with first on the valve body and take over mouth and the second adapter mouth, and its structure characteristic is that seal ring comprises the first seal ring and the second seal ring that stacks together.
Be provided with groove on described the first seal ring, be provided with projection on the second seal ring, this projection is inserted in the groove;
Perhaps, be provided with projection on the first seal ring, be provided with groove on the second seal ring, projection is inserted in the groove.
It is trapezoidal that the cross section of described groove and projection is respectively; Perhaps, the cross section of groove and projection is tapered respectively.
Be provided with the step for assembling the first seal ring and the second seal ring in the described valve body, valve pocket is crimped on the first seal ring and the second seal ring.
The described first axis and the second axis of taking over mouth of taking over mouth arranges in the same way; The axis of valve rod and the second axis of taking over mouth are angle and intersect.
Described angle is 30～70 °.
The intersect vertical axis of the axis of described the first adapter mouth and the second adapter mouth, the axis of the axis of valve rod and the first adapter mouth or the axis of the second adapter mouth are vertical.
Seal ring in the utility model comprises the first seal ring and the second seal ring that stacks together, and is provided with groove on the first seal ring, is provided with projection on the second seal ring, and this projection is inserted in the groove; Perhaps, be provided with projection on the first seal ring, be provided with groove on the second seal ring, projection is inserted in the groove; When the first seal ring and the second seal ring pressurized, distortion slightly outwardly, both can improve the first seal ring and the second seal ring respectively and the compactness between the valve interior wall, can also improve the first seal ring and the second seal ring respectively and the compactness between the valve rod.
The utility model can be set to the cooling stop valve at right angle as required, also can be set to the cooling stop valve at oblique angle, the cooling stop valve of Y type namely, it both can be used for air conditioner, also can be used for heat pump water-heating machine, have characteristics simple and reasonable, good seal performance.
