Description
Technical field
The utility model relates to ball valve technical fields, and in particular to one kind can reduce the ball valve of valve rod torque.
Background technique
Ball valve, including valve rod, connection supporting plate, gland flange, valve body and sphere；Sphere is located in valve body, valve rod and sphere
It is connected, gland flange is sleeved on valve rod, and gland flange is fixed in the top of valve body, is connected supporting plate and is sleeved on valve rod, even
The top that supporting plate is located at gland flange is connect, connection supporting plate is fixed in gland flange, and valve rod is by valve body, gland flange and connection branch
Plate assembly constraint, the upper end of sphere is constrained by the lower end of valve rod to be fixed.
In order to keep the balance of valve rod, the necessarily reaction by gland flange and connection supporting plate to it of the middle part of valve rod
Power forms the region of an extruding between gland flange, connection supporting plate and the middle part of valve rod in this way.Valve rod central region it is micro-
Seeing profile is rough, roughness increase, once valve opening, gland flange, the central region for connecting supporting plate and valve rod
Between frictional force will significantly increase, and then increase the unlatching torque of ball valve；Also due to the increase of frictional force, valve rod
Valve rod of the surface hardness of central region not by rolling processing is high, and hardness is reduced not high-wearing feature, long-term switch ball
Valve will exacerbate the abrasion of valve rod.
Utility model content
The purpose of this utility model is to provide the ball valves that one kind can reduce valve rod torque, can reduce valve rod and gland method
The blue relative friction forces between connection supporting plate, and then reduce the open and close torque of ball valve.
To achieve the above object, the utility model provides the following technical solutions:
A kind of ball valve reducing valve rod torque, including valve rod, connection supporting plate, gland flange, valve body and sphere；Sphere position
In in valve body, valve rod is connected with sphere, and gland flange is sleeved on valve rod, and gland flange is fixed in the top of valve body, connection
Supporting plate is sleeved on valve rod, and connection supporting plate is located at the top of gland flange, and connection supporting plate is fixed in gland flange, and valve rod is by valve
Body, gland flange and connection supporting plate assembly constraint, the upper end of sphere is constrained by the lower end of valve rod to be fixed, the outer surface of valve rod and company
Supporting plate and the corresponding position of gland flange is connect to handle by rolling.
Preferably, the outer surface of valve rod is handled by rolling.
The working principle of the utility model are as follows: after carrying out rolling and processing to the central region of valve rod, the surface that was rolled
Nao-and micro relief modified, surface roughness reduces, and in this way when opening ball valve, gland flange connects supporting plate and valve rod
Central region between frictional force become smaller, moment of friction becomes smaller therewith, and then the unlatching torque of ball valve is caused to become smaller.And due to
The raising of the surface hardness and wearability of the valve rod rolled over, the service life of valve rod is elongated, and the service life of ball valve is also therewith
It is elongated.
The utility model has the following beneficial effects: it can reduce valve rod and gland flange and connect the relative friction between supporting plate
Power, and then reduce the open and close torque of ball valve.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1,
A kind of ball valve reducing 1 torque of valve rod, including valve rod 1, connection supporting plate 2, gland flange 3, valve body 4 and sphere 5；
Sphere 5 is located in valve body 4, and valve rod 1 is connected with sphere 5, and gland flange 3 is sleeved on valve rod 1, and gland flange 3 is fixed in valve
The top of body 4, connection supporting plate 2 are sleeved on valve rod 1, and connection supporting plate 2 is located at the top of gland flange 3, and connection supporting plate 2 is fixed on
In gland flange 3, valve rod 1 is by valve body 4, gland flange 3 and connection 2 assembly constraint of supporting plate, and the upper end of sphere 5 is by under valve rod 1
End constraint is fixed, and the outer surface of valve rod 1 position corresponding with connection supporting plate 2 and gland flange 3 is handled by rolling.
The region corresponding with connection supporting plate 2 and gland flange 3 of the outer surface of a-quadrant, that is, valve rod 1 shown in Fig. 1.
The outer surface of valve rod 1 is handled by rolling.
The working principle of the utility model are as follows: after carrying out rolling and processing to the central region of valve rod 1, the surface that was rolled
Nao-and micro relief modified, surface roughness reduces, and in this way when opening ball valve, gland flange 3 connects supporting plate 2 and valve
Frictional force between the central region of bar 1 becomes smaller, and moment of friction becomes smaller therewith, and then the unlatching torque of ball valve is caused to become smaller.Again
Due to the raising of the surface hardness and wearability of the valve rod 1 rolled over, the service life of valve rod 1 is elongated, the service life of ball valve
Also elongated therewith.
The utility model has the following beneficial effects: it can reduce valve rod 1 and gland flange 3 and connect opposite between supporting plate 2
Frictional force, and then reduce the open and close torque of ball 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 deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
