Abstract
The utility model 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 utility model 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.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of gate valves with anti-wear gasket.
In order to achieve the above object, the utility model adopts the following technical solutions: a kind of gate valve with anti-wear gasket, feature
It is: including valve shaft, locknut, divided ring and valve deck；The middle part of the valve shaft is equipped with a circle limiting groove, the divided ring
A part 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
It is buckled 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, described to subtract
Cushion cover is ground on the valve shaft, the top of anti-wear gasket and the divided ring cooperate.
Preferably, sealing ring is equipped between the hair wrinkle and locknut.
The beneficial effects of the utility model are: compared with the existing technology, it is recessed that divided ring is limited in locknut lower part by the present apparatus
Radial positioning is carried out in slot, while locknut again limits the axial float of divided ring.New design greatly reduces the operation of valve
Torque.Valve shaft and divided ring are broken up into two bodies, and increase anti-wear gasket in divided ring lower part, greatly reduces the behaviour of valve
Make torque, the handwheel diameter that operation valve needs is reduced, to reduce production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment of the present utility model is described in detail in preferred embodiment.As shown in Figure 1, one
Kind has the gate valve of anti-wear gasket, including valve shaft 1, locknut 2, divided ring 3 and valve deck 4；The middle part of the valve shaft is equipped with a circle limit
Position groove 5, a part of the divided ring is mounted in the limiting groove, and the locknut lower part is equipped with stepped groove 6, on locknut
Portion is fixed on valve shaft, and stepped groove is buckled in the outside of divided ring, and the valve deck is fixed on the outside of the locknut；The valve deck
Bottom is equipped with anti-wear gasket 8, and on the valve shaft, the top of anti-wear gasket and the divided ring cooperate the anti-attrition cushion cover.By valve shaft
Two bodies are broken up into divided ring, and increase anti-wear gasket in divided ring lower part, the operation torque of valve is greatly reduced, reduces
The handwheel diameter that operation 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 the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
