Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of fixture of keeping in repair cut-off valve seat as shown in Fig. 1-4, comprise length and be greater than the base plate 1 of seat of stop valve 2 length, first fixed head 3, second fixed head 4 and the portable plate 5 parallel with seat of stop valve 2 horizontal axis, distance between described first fixed head 3 and the second fixed head 4 should be greater than the width of seat of stop valve 2, described portable plate 5 is arranged between the first fixed head 3 and the second fixed head 4, described first fixed head 3, second fixed head 4 and portable plate 5 are all perpendicular to base plate 1, and relative first fixed head 3 of described portable plate 5 can move horizontally.In the first fixed head 3 middle and upper part, corresponding stop valve 2 valve seat location is provided with screwed hole, and the bolt 6 coordinated with screwed hole is perpendicular to the first fixed head 3, and described inboard one end of bolt 6 is corresponding with portable plate 5.
As a kind of preferred structure, in order to keep the depth of parallelism of portable plate 5 and the first fixed head 3, gag lever post 7 can be provided with in portable plate 5 middle and upper part, described gag lever post 7 is vertically fixed on portable plate 5, described first fixed head 3 is provided with the spacing hole coordinated with gag lever post 7, and spacing hole is two and is separately positioned on the both sides of the first fixed head 3 upper screwed hole.On portable plate 5 two gag lever post 7 is inserted in the spacing hole on the first fixed head 3, position-limiting action is played to portable plate 5, make portable plate 5 keep vertical with base plate 1, parallel with the second fixed head 4 with the first fixed head 3.
The thickness of described base plate 1, first fixed head 3, second fixed head 4 and portable plate 5 is chosen as 8 ~ 10mm, distance between described first fixed head 3 and the second fixed head 4 adds 50mm again for the width of repaiied seat of stop valve 2, the specification of described bolt 6 is M16, long 70mm, described spacing hole diameter is 10.5mm, described gag lever post 7 diameter is 10mm, and each size can suitably adjust as required.
