Abstract
The utility model discloses a flat gate valve which comprises a valve body, a valve seat, a wedge disc, a valve rod, a valve cover and a hand wheel. The valve rod is arranged in an inner hole of the valve cover in a penetrating mode, the upper end of the valve rod is connected with the hand wheel, the lower end of the valve rod is connected with the wedge disc, the wedge disc is arranged inside the valve body, the valve cover is connected with the valve body through bolts, and middle holes with the same diameter are formed in the lower end of the valve cover and the upper end of the valve body respectively. Trapezoid grooves are formed in the lower end face of the valve cover and the upper end face of the valve body respectively, the size of trapezoid groove of the valve cover is the same as the size of the trapezoid groove of the valve body, the opening position of the trapezoid groove of the valve cover is the same as the opening position of the trapezoid groove of the valve body, and the trapezoid grooves are formed inside the bolts. Sealing packing is filled into internal space defined by the trapezoid groove of the valve cover and the trapezoid groove of the valve body.
Description
Technical field
The utility model relates to a kind of plate valve.
Background technique
Existing a kind of plate valve, contain valve body, valve seat, flashboard, valve rod, valve gap and handwheel, valve rod is installed in the endoporus of valve gap, the valve rod upper end is connected with handwheel, the valve rod lower end is connected with flashboard, flashboard is positioned at valve inner, valve gap and valve body are bolted, the valve gap lower end is respectively equipped with the valve body upper end mesopore that diameter is identical, be provided with seal ring in mesopore, described seal ring is annular tubular structure, and upper half part of described seal ring outer side surface and lower half portion contact with the mesopore inner side surface of valve gap and the mesopore inner side surface of valve body respectively.In above-mentioned plate valve, because seal ring is annular tubular structure, when the bolt between valve gap and valve body carries out seal ring when fastening, easily be out of shape, cause poor sealing performance, because seal ring need to be used more material, cause manufacture cost high again.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of good seal performance and the low plate valve of cost.
For solving the problems of the technologies described above, a kind of plate valve of the utility model, contain valve body, valve seat, flashboard, valve rod, valve gap and handwheel, valve rod is installed in the endoporus of valve gap, the valve rod upper end is connected with handwheel, the valve rod lower end is connected with flashboard, flashboard is positioned at valve inner, valve gap and valve body are bolted, the valve gap lower end is respectively equipped with the valve body upper end mesopore that diameter is identical, described valve gap lower end surface and valve body upper-end surface are respectively equipped with dovetail groove, the dovetail groove of described valve gap and the dovetail groove of valve body are measure-alike, aperture position overlaps and is positioned at the bolt inboard, the inner space that the dovetail groove of described valve gap and the dovetail groove of valve body surround is provided with stuffing box packing.
In above-mentioned plate valve, due to the valve gap lower end surface and the valve body upper-end surface is provided with dovetail groove and two dovetail groove inside are provided with stuffing box packing, when the bolt between valve gap and valve body carries out when fastening, valve gap compresses valve body, thereby has compressed the sealing material of two dovetail groove inside, has enriched seal clearance, so good seal performance, owing to adopting dovetail groove and stuffing box packing to replace original seal ring structure, reduced the material of required use, thereby reduced cost again.
the accompanying drawing explanation
The structural representation that Fig. 1 is a kind of plate valve of the utility model.
The I part enlarged view that Fig. 2 is Fig. 1.
1. handwheels in figure, 2. valve rod, 3. valve gap, 4. mesopore, 5. valve body, 6. flashboard, 7. valve seat, 8. dovetail groove, 9. stuffing box packing.
embodiment
Fig. 1, in Fig. 2, a kind of plate valve of the utility model, contain valve body 5, valve seat 7, flashboard 6, valve rod 2, valve gap 3 and handwheel 1, valve rod 2 is installed in the endoporus of valve gap 3, valve rod 2 upper ends are connected with handwheel 1, valve rod 2 lower ends are connected with flashboard 6, flashboard 6 is positioned at valve body 5 inside, valve gap 3 is bolted with valve body 5, valve gap 3 lower ends are respectively equipped with valve body 5 upper ends the mesopore 4 that diameter is identical, described valve gap 3 lower end surfaces and valve body 5 upper-end surfaces are respectively equipped with dovetail groove 8, the dovetail groove 8 of described valve gap 3 is measure-alike with the dovetail groove 8 of valve body 5, aperture position overlaps and is positioned at the bolt inboard, the dovetail groove 8 of described valve gap 3 is provided with stuffing box packing 9 with the inner space that the dovetail groove 8 of valve body 5 surrounds.In above-mentioned plate valve, due to valve gap 3 lower end surfaces and valve body 5 upper-end surfaces are provided with dovetail groove 8 and two dovetail groove 8 inside are provided with stuffing box packing 9, when the bolt to 5 of valve gap 3 and valve bodies carries out when fastening, valve gap 3 compresses valve body 5, thereby has compressed the sealing material of two dovetail groove 8 inside, has enriched seal clearance, so good seal performance, owing to adopting dovetail groove 8 and stuffing box packing 9 to replace original seal ring structure, reduced the material of required use, thereby reduced cost again.
