This sealing connecting structure's disk seat the pine can not appear and move back, and is sealed effectual.
Description
Technical field
The utility model relates to hydraulic control valve, is specifically related to the Hermetical connecting structure of hydraulic control valve valve seat.
Background technique
Hydraulic control valve take pipe medium pressure as power, carries out the valve opening and closing, regulate, be made up of major parts such as valve body, valve seat, flap, diaphragm, valve gaps.Water-inlet cavity and water chamber is provided with in valve body, next door between water-inlet cavity and water chamber is provided with valve seat mounting hole, described valve seat mounting hole is built with valve seat, water-inlet cavity is communicated with by the through hole in valve seat with water chamber, it is convex that valve seat upper end is provided with ring, is provided with seal ring between the lower surface that described ring is convex and the end face of valve seat mounting hole site in water chamber.The Placement of above-mentioned valve seat, the vibrations produced in conduit running process easily cause valve seat pine to move back, and cause fluid leakage.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of valve seat not easily loose Hermetical connecting structure moved back, in order to avoid cause fluid leakage.
For solving the problems of the technologies described above, the utility model provides a kind of Hermetical connecting structure of hydraulic control valve valve seat of following structure, comprise valve body, water-inlet cavity and water chamber is provided with in valve body, next door between water-inlet cavity and water chamber is provided with valve seat mounting hole, described valve seat mounting hole is built with valve seat, water-inlet cavity is communicated with by the through hole in valve seat with water chamber, it is convex that valve seat upper end is provided with ring, seal ring is provided with between the lower surface that described ring is convex and the end face of valve seat mounting hole site in water chamber, its structural feature is: the hole wall of described valve seat mounting hole is provided with top near valve seat mounting hole shaft axis and below away from the slope that valve seat mounting hole shaft axis is arranged, described valve seat is bolted with the puller bolt withstood on described slope.
The end face of described valve seat mounting hole site in water chamber and the convex lower surface of described ring are all perpendicular to valve seat mounting hole shaft axis.
The lower surface that described ring is convex is equipped with seal ring mounting groove, and described seal ring is positioned at seal ring mounting groove.
The hole wall of described valve seat mounting hole is provided with cross section and projects V-shaped annular groove, and the upper trough wall surface of annular groove forms described slope.
Described slope is located at the lower end of the hole wall of valve seat mounting hole.
The assembly relation of described valve seat mounting hole and valve seat is interference fit.
Seal ring is enclosed within valve seat, and valve seat loads in valve seat mounting hole, then rotate puller bolt to make it to withstand on slope, be rotated further puller bolt, move down until ring on valve seat is convex is tightly pressed on the end face of valve seat mounting hole site in water chamber by seal ring at the effect lower valve base of slope, the installation of valve seat can be completed.Due to the locking effect of slope, even if produce vibrations in conduit running process, valve seat pine also can not be caused to move back, thus liquid can be avoided to leak between valve seat and the hole wall of valve seat mounting hole.In addition, the assembly relation of valve seat mounting hole and valve seat is interference fit, and can be formed between valve seat and the hole wall of valve seat mounting hole and firmly seal, add the soft seal of seal ring, can realize double seal, thus sealing effect is better.
In sum, the utility model has the advantage of: valve seat there will not be pine to move back, good sealing effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is the schematic diagram of the first hydraulic control valve Hermetical connecting structure;
Fig. 2 is the A portion enlarged view in Fig. 1;
Fig. 3 is the schematic diagram of the second hydraulic control valve Hermetical connecting structure;
Fig. 4 is the B portion enlarged view in Fig. 3.
Embodiment
The Hermetical connecting structure of the first hydraulic control valve valve seat as shown in Figure 1, comprise valve body 1, water-inlet cavity 2 and water chamber 3 is provided with in valve body 1, next door 4 between water-inlet cavity 2 and water chamber 3 is provided with valve seat mounting hole, described valve seat mounting hole is built with valve seat 5, and the assembly relation of described valve seat mounting hole and valve seat 5 is interference fit.Water-inlet cavity 2 is communicated with by the through hole in valve seat 5 with water chamber 3, and valve seat 5 upper end is provided with ring convex 7, and the lower surface of the end face 6 of described valve seat mounting hole site in water chamber 3 and described ring convex 7 is all perpendicular to valve seat mounting hole shaft axis.The lower surface of described ring convex 7 is equipped with seal ring mounting groove, between the lower surface of described ring convex 7 and the end face of valve seat mounting hole site in water chamber 3, is provided with the seal ring 8 being positioned at seal ring mounting groove.The hole wall of described valve seat mounting hole is provided with top near valve seat mounting hole shaft axis and below away from the slope 9 that valve seat mounting hole shaft axis is arranged.The generation type of slope 9 is as described below: see figures.1.and.2, and the hole wall of described valve seat mounting hole is provided with the annular groove 11 that cross section projects V-shaped, and the upper trough wall surface of annular groove 11 forms described slope 9.Described valve seat 5 is bolted with the puller bolt 10 withstood on described slope 9.
