On the other hand, the valve plate can increase the stable effect to the valve plate under closed state, also alleviates the valve plate to the wearing and tearing of valve body.
Drawings
Fig. 1 is a schematic structural view of the manual gate valve of the present invention.
The reference numbers in the figures are as follows: the valve comprises a valve box 1, a valve body 2, a threaded rod 3, a fixed seat 4, a rotating disc 5, a bearing 6, a sleeve 7, a pin shaft 8, a linkage plate 9, a screw rod 10, a dish-shaped nut 11, a valve plate 12, a first sealing ring 13 and a second sealing ring 14.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the utility model discloses a manual push-pull valve, including the valve box 1 and the valve body 2 that set up from top to bottom, be provided with interlock board 9 in the valve box 1, even have bearing 6 on the interlock board 9, the inner circle of bearing 6 even has sleeve 7, and the lower extreme of threaded rod 3 stretches into sleeve 7 internal fixation, and sleeve 7 has seted up first horizontal through-hole, and the horizontal through-hole of second has been seted up to the lower extreme of threaded rod 3, and round pin axle 8 passes first horizontal through-hole and second horizontal through-hole after-fixing.
Be provided with fixing base 4 on the valve box 1, valve box 1 and fixing base 4 are passed to the upper end of threaded rod 3, threaded rod 3 and 4 screw-thread fit of fixing base, and 3 upper ends of threaded rod are provided with rolling disc 5. The utility model discloses a rolling disc 5 rotates, drives interlock board 9 up-and-down motion.
The left side and the right side of the linkage plate 9 are respectively connected with a screw 10, the side of the valve box 1 is provided with a slot for the movement of the screw 10, and a butterfly nut 11 is screwed into the screw 10 and then contacts with the outer side of the valve box 1. Before the valve plate 12 needs to be opened or closed, the disc-shaped nut 11 is loosened, the disc-shaped nut 11 operates the rotating disc 5 at the moment to realize the opening or closing of the valve plate 12, then the disc-shaped nut 11 is screwed, and the linkage plate 9 and the valve box 1 are fixed through the screw rod 10. On one hand, after the valve plate 12 is opened and closed, the acting force between the threaded rod 3 and the fixed seat 4 is reduced, and the abrasion between the threaded rod and the fixed seat is reduced. On the other hand, when valve plate 12 is in the closed state, the effect of stabilizing valve plate 12 can be increased, and the wear of valve plate 12 on valve body 2 can also be reduced.
