In vivo, valve block is threaded in the inserting end of valve rod, and the other end of valve rod is extend out to outside valve deck, and limit convex is provided on valve rod
Platform, the first nut and the second nut are sleeved on valve rod, and the first nut is threadedly coupled with valve deck and is limited by positive stop lug boss
The axial movement of valve rod, the second nut are connect with the first nut thread, during use state, by rotary valve rod, and then drive valve
Body moves back and forth on valve rod so that the valve chamber access of valve body opens and closes.
The utility model, which further improves, to be, is offered in the middle part of the valve chamber access of valve body and is carved type sealing surface, for
The use of type respective outer side edges is carved on the outside of valve block.
The utility model, which further improves, to be, valve block is connect with valve rod by trapezoidal thread.
The utility model, which further improves, to be, is further included handwheel, is arranged on the external part of valve rod.
The utility model, which further improves, to be, the first washer is provided between valve deck and valve body.
The utility model, which further improves, to be, second packing ring, the second nut are provided between the first nut and valve rod
Third washer is provided between valve rod.
The utility model has following advantageous effect：
A kind of Antileaking sluice valve provided by the utility model, including the valve body with hollow cavity, in the body top
Portion is provided with opening, and the opening upper cover is equipped with valve deck, valve rod is equipped in the valve deck, wherein, shape between valve deck and valve body
Into the cavity for having closing, valve block is in close contact when closed with valve body, to ensure the sealing performance of gate valve.
Description of the drawings
Fig. 1 is a kind of structure diagram of vacuum gate valve of the utility model.
In figure：1- valve bodies, 2- valve blocks, 3- valve rods, the first washers of 4-, 5- valve decks, the first nuts of 6-, 7- second packing rings, 8-
Third washer, the second nuts of 9-, 10- handwheels.
Specific embodiment
This patent is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of vacuum gate valve provided by the utility model, including valve body 1, valve block 2, valve rod 3, valve deck 5,
One nut 6 and the second nut 9；Wherein, valve body 1 has hollow cavity, and the valve with inlet and outlet is opened up on the side wall of the cavity
Chamber access, top offer opening, and valve deck 5 is arranged on the top open part of valve body 1, and one end of valve rod 3 leads to from the center of valve deck 5
Road is stretched in the hollow cavity of valve body 1, and valve block 2 is threaded in the inserting end of valve rod 3, and the other end of valve rod 3 extend out to valve
Outside lid 5, positive stop lug boss is provided on valve rod 3, the first nut 6 and the second nut 9 are sleeved on valve rod 3, the first nut 6 and valve
Lid 5 is threadedly coupled and the axial movement of valve rod 3 is limited by positive stop lug boss, and the second nut 9 is threadedly coupled with the first nut 6, makes
It during with state, is moved back and forth on valve rod 3 by rotary valve rod 3, and then with moving valve 1 so that the valve chamber access of valve body 1 is opened
And closing.
Specifically, the valve chamber access for pipeline flow of media is offered in valve body 1, is had in the centre of valve chamber and valve
The valve block 2 of chamber fitted seal, valve rod 3 are connect with valve block 2 by trapezoidal thread, at the top of valve rod 3 equipped with handwheel 10, by turning
