Description
The utility model is about valve, more particularly, and about ball valve.
Ball valve is a kind ofly to come the universal machine product of media flow in the pilot line by changing its inner passage.It is widely used among each industrial department.
" mechanical engineering manual " the 14th volume the 7th chapter " valve mechanism and drive unit " that China China Machine Press publishes nineteen eighty-two discloses a kind of ball valve.This ball valve is provided with spring mechanism, but can not adjust arbitrarily.In addition, above-mentioned ball valve, when valve opening and closing, because the frictional force between spheroid and the valve seat is bigger, driving force is also bigger, and sealing surface of seat is easy to wearing and tearing, causes seepage and stuck.
The purpose of this utility model is the shortcoming that overcomes above-mentioned ball valve, a kind of good seal performance is provided, is difficult for causing seepage, is easy to assemble and keep in repair, can regulate, the ball valve of long service life.
The purpose of this utility model can be achieved by following structures.Ball valve of the present utility model contains valve rod (1), filler (3) bearing (4), valve body (5), flange (8), spring (10), seal ring (11), valve seat (12), spheroid (15), handle (16), adjust body (6), locknut (7), driving pin (9), bearing ring (13), described valve seat (12) is fixed on the bearing ring (13), be provided with driving pin (9) and spring (10) between bearing ring (13) and the adjustment body (6), rotate and move axially in order to transmit, adjust body (6) and be connected, and be locked with locknut (7) with valve body (5).
The physical dimension of above-mentioned valve seat (12) preferably adopts b 〉=3mm, φ d-φ c 〉=3mm, and α=90 °-160 ° are the best with 120 ° wherein.
Above-mentioned ball valve, if it is between spheroid (15) lower end supporting surface and valve body (5), be provided with spacer (14), then easy to maintenance.
Above-mentioned ball valve also can be provided with cam (2), and cam (2) is connected with valve rod (1).In case of necessity, also can on spheroid (15), have groove more than two.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is the main half sectional view of the utility model ball valve;
Fig. 2 is the structural representation of the valve seat (12) of the utility model ball valve.
Fig. 3 is for having the structural representation of groove on the spheroid (15) of the utility model ball valve;
Fig. 4 is the structural representation of the cam (2) of the utility model ball valve;
Fig. 5 is the application schematic representation of structure in fixing ball valve of the cam (2) of the utility model ball valve;
Fig. 6 is the application schematic representation of adjustable compensation sealing configuration of the present utility model in Float ball valve;
Fig. 7 is the application schematic representation of adjustable compensation sealing configuration of the present utility model in Fixed ball valve.
In the drawings, (1) valve rod, (2) cam, (3) filler, (4) bearing, (5) valve body, (6) adjust body, (7) locknut, (8) flange, (9) driving pin, (10) spring, (11) seal ring, (12) valve seat, (13) bearing ring, (14) spacer, (15) spheroid, (16) handle.
Now the utility model will be further described in conjunction with the accompanying drawings.
In Fig. 1, valve seat (12) is fixed on the bearing ring (13), is provided with driving pin (9) and spring (10) between bearing ring (13) and the adjustment body (6), rotates and moves axially in order to transmit.Adjust body (6) and be connected, and be locked with locknut (7) with valve body (5).
When the face pressure between spheroid (15) and the valve seat (12) need be adjusted, utilize adjustable compensation device of the present utility model to be easy to be achieved.For example, can become flexible locknut (7) earlier, regulate adjust body (6) then,, it is rotated and move axially by driving pin (9) and spring (10) transmission bearing ring (13) and valve seat (12).When bearing ring (13) rotated, valve seat (12) can change relative contact position with spheroid (15), made it be in best contact and sealing state, then locked locknut (7), to keep stable.
Adjust body (6) and can be designed to the threaded adjustment structure as required, gear is adjusted structure, and worm and gear is adjusted structure, and forms such as structure are adjusted on the inclined-plane.
The adjustment body (6) of present embodiment adopts thread connecting mode.It is connected with valve body (5) by screw thread, and its inboard nose circle face is provided with the rigging position of driving pin (9) and spring (10).Justify contact surface in two internal circular surfaces adjusting body (6) and bearing ring (13) and the valve body (5) and be provided with seal ring (11).
For further improving sealability and for ease of maintenaince, between spheroid (15) lower end supporting surface and valve body (5), spacer (14) is set preferably.
Ball valve of the present utility model also can be provided with cam (2), and it is connected with valve rod (1).Cam (2) can be used for regulating the gap between spheroid (15) and the valve seat (12), when spheroid (15) is rotated, does not rub between the two.
The Placement of ball valve of the present utility model and pipeline can adopt the various forms of called optical imaging.What this example adopted is to be connected by flange (8).Certainly, as required, also can adopt internal thread, outside thread, the first-class Connecting format of loose joint.
Fig. 2 illustrates the structure of valve seat (12).Usually, the physical dimension b and the α angle of valve seat (12) should be: b 〉=3mm, and φ d-φ c 〉=3mm, α=90 °-60 ° are the best with 120 °, and are easy to process.
Fig. 3 illustrates the structure of spheroid (15).Spheroid (15) has the groove more than two.In fact, they are exactly decompressing groove.When spheroid (15) rotated with 0 °-90 °, fluid produced impact force to valve seat (12), can damage the sealing surface of valve seat (12).Decompressing groove has been arranged, just can make spheroid (15), in the process of valve opening and closing, reduced the impact force that fluid produces valve seat (12) because some fluid along trench flow to the other end.This ball valve also can be used for the throttling occasion.
Fig. 4 illustrates the structure of cam (2).The center of circle O of cam (2)
1Be positioned on the position of the perpendicular bisector of 2 of AB and OB line crosspoint; The center of circle O of cam (2)
2The perpendicular bisector and the OLB that are positioned at 2 of A ' B ' are " on the position of line crosspoint.
When spheroid (15) rotates; cam (2) forwards 90 ° with spheroid (15) to from 0 ° simultaneously; bearing ring (13) is pushed to both sides; make in the process of valve opening and closing, not produce between spheroid (15) and the valve seat (12) and contact; not friction, thereby reduce moment of torsion, played the effect of protection valve seat (12); and reduced the rotation power consumption, played the effect of saving the energy.
Fig. 5 illustrates cam (2) and is applied to structure in the Fixed ball valve.Cam (2) can make valve reduce moment of torsion and friction in the process that opens and closes.
Fig. 6 and Fig. 7 illustrate the application of the utility model in Float ball valve and Fixed ball valve.What these two kinds of examples adopted is the Connecting format of internal thread and external pipe.
Ball valve of the present utility model compared with prior art has the following advantages:
1. the sealing surface of seat of ball valve can be regulated and auto-compensation, and even wearing has prolonged service life, good seal performance.
2. assembly technology is simple, and the face pressure between valve seat and sphere can be adjusted, and is easy to use.
3. reduce friction, reduce driving torque, play the effect of energy savings.
