Abstract
The utility model relates to a sealing structure for a plate type sluice valve. A valve rod 3 is connected with a valve plate 1, the valve plate 1 is provided with a straight plane surface 4 and an oblique plane surface 5, and the straight plane surface 4 and the oblique plane surface are matched with the end surfaces of a valve seat 2; the valve plate 1 are arranged inside the valve seat 2. The sealing structure has the advantages of good sealing performance, easy installation, convenient and flexible opening, and long service life.
Description
The utility model relates to flat Gate-valve sealing technical field of structures.
The valve plate of existing flat gate valve all is the equal thickness flat board, with valve seat certain matching gap is arranged, and sealability is bad, under the lower situation of pressure leakage is arranged.
Order of the present utility model is that valve plate one end face with flat gate valve is designed to tapered plane, makes this valve seal performance better, opens more light and flexible.
The utility model is achieved in that valve rod 3 is connected with valve plate 1, straight plane 4 and tapered plane 5 are arranged on the valve plate 1 and matches with valve seat 2 end faces, and valve plate 1 is in valve seat 2.
The utility model has the advantages that: good seal performance, open light and flexible, reasonable in design, cost is low, and is easy for installation, long service life.
Below in conjunction with accompanying drawing, the utility model is described further with embodiment:
This accompanying drawing is flat Gate-valve sealing structural representation.
In the accompanying drawing: 1, valve plate, 2, valve seat, 3, valve rod, 4, straight plane, 5, tapered plane.
Depress downwards when valve cuts out valve rod 3 make valve plate 1 under the promotion of valve rod 3 to lower slider, valve plate 1 is more to lower slider, straight plane 4 on it and tapered plane 5 are tight more with cooperating of valve seat 2, seal until forming.
During opening of valves, upwards poppet stem 3 is upwards mentioned valve plate 1 under the drive of valve rod 3, until valve opening, and the medium circulation.
Claims (1)
1, flat Gate-valve sealing structure is characterized in that: valve rod (3) is connected with valve plate (1), straight plane (4) and tapered plane (5) are arranged on the valve plate (1) and matches with valve seat (2) end face, and valve plate (1) is in valve seat (2).
