Description
Technical field
The utility model belongs to valve body structure design field, and more particularly, it relates to a kind of ball valve.
Background technique
Ball valve is all to present sphere at inlet/outlet place, thereby blocks mobile.Because only need 90-degree rotation and very little moment just can close tightly, and the body cavity current of opening completely provide resistance very little, straight-through runner, there is suitable directly doing and open and close use, also can be used as the use of throttling and control flow.Its structure generally comprises valve body, valve rod and is arranged on the spherical valve core in valve body, in valve body, be provided with runner, spherical valve core is provided with the passage matching with runner, and spherical valve core valve body is provided with the screw thread being connected with other pipe fitting, valve rod lower end is fixedly connected with spherical valve core, and the other end is provided with handle.The two ends of spherical valve core are provided with seal ring, so just can prevent from leaking, and still, if hydraulic pressure is excessive, just likely can causes seal ring to lose sealing effect, thereby cause ball valve to leak.Current existing ball valve has adopted the adjustable design of sealing effect for this defect, thereby solved problem, yet, in needs regulating seal property, will use other adjustment means, and if staff leaves behind adjustment means, just cannot implement to have regulated, therefore, be necessary to improve on ball valve for this problem.
Model utility content
The utility model, for above-mentioned deficiency, provides a kind of ball valve that carries adjustment means.
For achieving the above object, the utility model provides following technological scheme:
A kind of ball valve, comprise valve body, be arranged on valve rod and spherical valve core in valve body, in described valve body, be provided with runner, described spherical valve core is provided with the passage matching with described runner, described valve body is provided with screw thread, the lower end of described valve rod is fixedly connected with described spherical valve core, and the other end extends described valve body and is provided with handle; It is characterized in that: in described valve body, be provided with seal arrangement, described seal arrangement comprises regulating block and seal ring, described regulating block is provided with the through hole matching with described passage, described regulating block is connected with described valve body screw thread, described seal ring is nested on described regulating block one end near described spherical valve core, one end of the relatively described seal ring of described regulating block is provided with at least two draw-in grooves, and described handle is provided with the fixture block coordinating with described draw-in groove, and described handle and described valve rod removably connect.
By adopting technique scheme, described seal arrangement is arranged in runner, described regulating block can precession described in valve body, owing to being nested with described seal ring on described regulating block, when described regulating block is screwed into certain position, described seal ring and described spherical valve core close contact, reach the effect of sealing; When needs regulate sealing effect, only need to take off described handle, described fixture block is aimed to described draw-in groove, then rotate described handle, thereby achieve the goal.Adopt such scheme, staff does not just need to carry adjustment means, has avoided leaving behind the situation of adjustment means.
The utility model is further set to: described handle comprises handle bar, and described handle bar is provided with the sleeve pipe coordinating with described valve rod.
The utility model is further set to: described valve rod is provided with annular protrusion, is provided with the annular groove coordinating with described annular protrusion in described sleeve pipe.
By adopting technique scheme, described handle is socketed by sleeve pipe and described valve rod, when taking off or reinstalling, more convenient than traditional mode being screwed; And by above-mentioned annular protrusion and annular groove are set, both cooperatively interact, just can make described taper knob be enclosed within firmly on described valve rod, only need firmly by or motive force described in handle just can be loaded onto or be taken off.
The utility model is further set to: described fixture block is positioned at the another side of relatively described sleeve pipe on described handle bar, and one end of described handle bar is partial in the position of described fixture block.
By adopting technique scheme, take off described handle, when described fixture block being sticked into described draw-in groove and rotating described regulating block, owing to having adopted above-mentioned setting, the moment while just having reduced to rotate, therefore only needs by less power, just can realize rotation.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.
A kind of ball valve, comprise valve body 1, be arranged on valve rod 2 and spherical valve core in valve body 1, in described valve body 1, be provided with runner, described spherical valve core is provided with the passage matching with described runner, described valve body 1 is provided with screw thread, the lower end of described valve rod 2 is fixedly connected with described spherical valve core, and the other end extends described valve body 1 and is provided with handle 3; In described valve body 1, be provided with seal arrangement 4, described seal arrangement 4 comprises regulating block 42 and seal ring 41, described regulating block is provided with the through hole 422 matching with described passage, described regulating block 42 is threaded with described valve body 1, described seal ring 41 is nested on described regulating block 42 one end near described spherical valve core, one end of the relatively described seal ring 41 of described regulating block 42 is provided with at least two draw-in grooves 421, described handle 3 is provided with the fixture block coordinating with described draw-in groove 421, and described handle 3 removably connects with described valve rod 2.
From Fig. 1 to Fig. 2, the present embodiment is incorporated into adjustment means on handle 3, the fixture block specifically arranging on handle 3.The concrete regulative mode of the present embodiment is: described regulating block 42 can precession valve body 1 in, owing to being nested with described seal ring 41 on regulating block 42, so when regulating block 42 is screwed into certain position, seal ring 41 just can with valve body 1 in spherical valve core close contact, reach the effect of sealing; If the interior hydraulic pressure of valve body 1 increases, cause ball valve to leak, that just need to regulate the sealing effect of seal arrangement 4, according to such scheme, only need to take off described handle 3, the fixture block on handle 3 321 is aimed to the draw-in groove 421 arranging on regulating block 42, then handle with sleeve 3, make seal ring 41 tightr with contacting of spherical valve core, thereby reach the object that strengthens sealing effect.
In the present embodiment, the concrete structure of handle 3 is: handle 3 comprises handle bar 32, in the middle of described handle bar 32, be installed with sleeve pipe 31, described sleeve pipe 31 is positioned at the middle part of described handle bar 32 and vertical with it, in addition, described valve rod 2 is provided with annular protrusion 21, is provided with the annular groove 312 coordinating with described annular protrusion 21 in described sleeve pipe 31.
Adopt above-mentioned Placement, described handle 3 is directly by sleeve pipe 32 and described valve rod 2 sockets, when taking off or reinstalling, more more convenient than traditional mode being screwed like this.In addition, annular protrusion 21 and the annular groove 312 of increase can block mutually, so just can make handle 3 be enclosed within firmly on described valve rod 2.
A preferred version for described fixture block 321 is: as shown in Figure 1, fixture block 321 is positioned at another side relative with described sleeve pipe 32 on described handle bar 32, and one end of described handle bar 32 is partial in the position of described fixture block 321.
Such setting is for when using the described regulating block 42 of handle 3 rotation, owing to having adopted above-mentioned setting, has reduced moment of rotation, so only needs, by less power, just can realize rotation, has reached labour-saving object.
