Abstract
The present invention relates to ball valve technical field more particularly to a kind of gate valves with anti-wear gasket, including valve shaft, locknut, divided ring and valve deck；The middle part of the valve shaft is equipped with a circle limiting groove, a part of the divided ring is mounted in the limiting groove, and the locknut lower part is equipped with stepped groove, and locknut top is fixed on valve shaft, stepped groove is buckled in the outside of divided ring, and the valve deck is fixed on the outside of the locknut；The bottom of the valve deck is equipped with anti-wear gasket, and on the valve shaft, the top of anti-wear gasket and the divided ring cooperate the anti-attrition cushion cover.Divided ring is limited in locknut lower recess and carries out radial positioning by the present apparatus, while locknut again limits the axial float of divided ring.New design greatly reduces the operation torque of valve.
Description
Technical field
The present invention relates to ball valve technical field more particularly to a kind of gate valves with anti-wear gasket.
Background technique
Divided ring is installed on the axial positioning structure valve shaft of inside screw nonrising stem type gate valve valve rod, has locknut to limit its axial direction on divided ring and alters
It is dynamic.When valve shaft rotates, divided ring can loosen outward in existing design, rub valve deck inner wall to increase operation torque.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide a kind of gate valve with anti-wear gasket.
To achieve the above object, using following technical scheme: a kind of gate valve with anti-wear gasket, feature exist the present invention
In: including valve shaft, locknut, divided ring and valve deck；The middle part of the valve shaft be equipped with one circle limiting groove, the one of the divided ring
It is partially installed in the limiting groove, the locknut lower part is equipped with stepped groove, and locknut top is fixed on valve shaft, stepped groove button
In the outside of divided ring, the valve deck is fixed on the outside of the locknut；The bottom of the valve deck is equipped with anti-wear gasket, the anti-attrition
On the valve shaft, the top of anti-wear gasket and the divided ring cooperate cushion cover.
Preferably, sealing ring is equipped between the hair wrinkle and locknut.
The beneficial effects of the present invention are: compared with the existing technology, divided ring is limited in locknut lower recess by the present apparatus
Radial positioning is carried out, while locknut again limits the axial float of divided ring.New design greatly reduces the operation torque of valve.
Valve shaft and divided ring are broken up into two bodies, and increase anti-wear gasket in divided ring lower part, the operation for greatly reducing valve is turned round
Square reduces the handwheel diameter that operation valve needs, to reduce production cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.As shown in Figure 1, a kind of band
There are the gate valve of anti-wear gasket, including valve shaft 1, locknut 2, divided ring 3 and valve deck 4；It is recessed that the middle part of the valve shaft is equipped with a circle limit
Slot 5, a part of the divided ring are mounted in the limiting groove, and the locknut lower part is equipped with stepped groove 6, and locknut top is solid
It is scheduled on valve shaft, stepped groove is buckled in the outside of divided ring, and the valve deck is fixed on the outside of the locknut；The bottom of the valve deck
Equipped with anti-wear gasket 8, on the valve shaft, the top of anti-wear gasket and the divided ring cooperate the anti-attrition cushion cover.By valve shaft with it is right
Open loop is broken up into two bodies, and increases anti-wear gasket in divided ring lower part, greatly reduces the operation torque of valve, reduces behaviour
The handwheel diameter for making valve needs, to reduce production cost.
Sealing ring 7 is equipped between the hair wrinkle and locknut.Improve the leakproofness between valve shaft and locknut.
Divided ring is limited in locknut lower recess and carries out radial positioning by the present apparatus, while locknut again limits divided ring
Axial float.New design greatly reduces the operation torque of valve.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
Claims (2)
1. a kind of gate valve with anti-wear gasket, it is characterised in that: including valve shaft, locknut, divided ring and valve deck；The valve shaft
Middle part is equipped with a circle limiting groove, and a part of the divided ring is mounted in the limiting groove, and the locknut lower part is equipped with
Stepped groove, locknut top are fixed on valve shaft, and stepped groove is buckled in the outside of divided ring, and the valve deck is fixed on the outer of the locknut
Portion；The bottom of the valve deck is equipped with anti-wear gasket, and the anti-attrition cushion cover is on the valve shaft, the top of anti-wear gasket and the divided ring
Cooperation.
