Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of friction member and easily changes formula valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.According to the difference of spool shape in valve, can be divided into ball valve, butterfly valve, mitre velve etc.Wherein the open-shut device of ball valve is spheroid, by valve rod, driven, and the valve rotating around the axis of valve rod.Be mainly used in blocking or connecting the medium in pipeline, also can be used for adjusting and the control of fluid.Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.It has the action of 90-degree rotation, and faucet body is spheroid, has manhole or passage by its axis.
The faucet body of ball valve be spheroid when rotated, and between valve body or other waterproof case for kinetic friction, surface friction drag is larger, spool or other waterproof friction member ratio are easier to damage; But because the spool of ball valve is spheroid, be assemblied in valve inner and be difficult to dismounting.So generally, when ball valve is impaired because valve body rubs, conventionally directly change whole valve, and direct discarded the losing of old valve caused huge waste.
Summary of the invention
For above problem, it is a kind of simple in structure that the utility model provides, and the friction portion of valve holds easily changeable friction member and easily changes formula valve.
The utility model solves the technological scheme that its technical problem adopts: this friction member easily changes formula valve and comprises valve body, spool, upper compression leg, lower compression leg, upper cover, lower cover; Described valve body is that cross is shaft-like, its antero posterior axis to and be axially processed with respectively up and down the through hole running through, described upper compression leg, lower compression leg are assemblied in the upward and downward axis hole of described valve body, described spool bottom is spherical, top was the shaft-like of the centre of sphere, the spherical part of described spool is assemblied between described upper compression leg, lower compression leg, described upper compression leg was processed with the through hole in axle center, the upper boom of described spool is through the axis hole of described upper compression leg, fix with torsion member, the upper and lower end of described valve body is processed with respectively outside thread head; Described upper cover, lower cover assemble mutually by worm structure and the upper and lower end of described valve body respectively, described spool, upper compression leg, lower compression leg are pressed in the above-below direction axis hole of described valve body; Between described spool and upper compression leg, lower compression leg, the rotatable assembling of sealing, is designed with between this three with described valve body antero posterior axis to the axis hole running through.
As preferably, described friction member easily changes formula valve and also includes Biaxial spanner, described Biaxial spanner is that a mobile jib front end separates two minutes bars, within described minute, boom end is designed with mobile jib and divides the socket cap that bar is simultaneously vertical, and the top of described upper cover, the bottom of lower cover are processed with respectively assembling counterbore corresponding to two socket caps of Biaxial spanner.
As preferably, in the threaded walls of upper cover, lower cover, be respectively fitted with lock screw.
The beneficial effects of the utility model are: this friction member easily changes formula valve front end and back end can connect into respectively pipeline, by described torsion member, can twist described spool, make the front and back axis hole of described valve body run through or close, thereby realize the switching of valve.This valve mechanism is simple, and described spool, upper compression leg, lower compression leg are friction member, easily damages; After this valve is turned on described upper cover, lower cover respectively, just can easily described spool, upper compression leg, lower compression leg be extracted from the above-below direction axis hole of described valve body, the friction member damaging is changed, improved the utilization ratio of valve, simple to operate, even will valve body do not unload pipeline and just can carry out.
Accompanying drawing explanation
Fig. 1 is the structural representation that this friction member easily changes formula profile valve.
Fig. 2 is that described Biaxial spanner is at the upper structural representation that covers use.
Fig. 3 be described Biaxial spanner under cover the structural representation of use.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in embodiment in Fig. 1, this friction member easily changes formula valve and comprises valve body 1, spool 2, upper compression leg 3, lower compression leg 4, upper cover 5, lower cover 6; Described valve body 1 is that cross is shaft-like, its antero posterior axis to and be axially processed with respectively the through hole running through up and down, in the above-below direction axis hole of described valve body 1, need processing comparatively smooth.Described upper compression leg 2, lower compression leg 3 can use the high-abrasive materials such as tetrafluoroethylene to make, and are assemblied in the upward and downward axis hole of described valve body 1 with upper and lower corresponding position, and the upper and lower end of these two stretches out respectively the axle head of described valve body 1 above-below direction slightly.Described spool 2 bottoms are spherical, top was the shaft-like of the centre of sphere, the spherical part of described spool 2 is assemblied between described upper compression leg 3, lower compression leg 4, the upper bottom surface of the bottom surface of described upper compression leg 3 and described lower compression leg 4 is processed with respectively hemisphere face, just in time by the spherical compression parcel in the bottom of described spool 2.Described upper compression leg 3 was processed with the through hole in axle center, and the upper boom of described spool 2, through the axis hole of described upper compression leg 3, fixes with torsion member 7, and described torsion member is symmetrical spanner shape, by the upper end of screw and bond structure and described spool 2 bar portions, fixes.The upper and lower end of described valve body 1 is processed with respectively outside thread head; Described upper cover 5, lower cover 6 assemble mutually by worm structure and the upper and lower end of described valve body 1 respectively, described spool 2, upper compression leg 3, lower compression leg 4 are pressed in the above-below direction axis hole of described valve body 1; Between described spool 2 and upper compression leg 3, lower compression leg 4, the rotatable assembling of sealing, is designed with between this three with described valve body 1 antero posterior axis to the axis hole running through.
