Abstract
The utility model provides a manual ball valve which comprises a valve body, a ball body, valve bases, a valve rod and a handle. One end of the valve rod is fixedly connected with the ball body, the other end of the valve rod is fixedly connected with the handle, and the manual ball valve is characterized in that a first fluid through hole is formed in one side of the valve body, a threaded hole is formed in the other side of the valve rod, a compression nut is installed in the threaded hole in a screwed mode, a second fluid through hole is formed in the compression nut, a valve cavity is formed between the valve body and the compression nut, the ball body is arranged in the valve cavity, and the valve bases are arranged at the positions, matched with the ball body, of the valve body and the compression nut. According to the manual ball valve, a traditional two-piece-type ball valve structure is improved, a valve body on one side is changed into the compression nut, therefore, the structural length of the valve is greatly shortened, and the use range of the ball valve is expanded.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of manual ball valve.
Background technique
To be open-shut device (spheroid) driven by valve rod ball valve, and the valve rotated 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, according to the difference of driving mode, can be divided into: pneumatic ball valve, electric ball valve and manual ball valve.In hydraulic system or in some industrial pipelines, because installing space is narrow and small, valve mechanism length be there are certain requirements, manual ball valve, as widely used a kind of valve, is subject to the constraint of structure length equally.Traditional manual ball valve generally all comprises two valve bodies that are arranged on the spheroid left and right sides, and this makes the structure length of valve longer, and using scope is limited.
The model utility content
The utility model, for above-mentioned the deficiencies in the prior art, provides the manual ball valve that a kind of structure length is less.
The utility model is achieved by the following technical solution:
A kind of manual ball valve, comprise valve body, spheroid, valve seat, valve rod and handle, and an end of described valve rod is fixedly connected with spheroid, and the other end is fixedly connected with handle; It is characterized in that, a side of described valve body is provided with the first fluid through hole, and opposite side is provided with tapped hole, screws on described tapped hole a gland nut is installed, and is provided with the second fluid through hole on described gland nut; Form a valve pocket between valve body and gland nut, in described valve pocket, be provided with spheroid, valve body be provided with valve seat with the spheroid place of matching on gland nut.
Manual ball valve described in the utility model improves for traditional two-piece type ball-valve structure, and wherein a side valve body is changed in quality into a gland nut, thereby has greatly shortened the structure length of this valve, has enlarged the using scope of ball valve.
Further, the periphery of described gland nut also is provided with one for sealing the O type circle of valve pocket.
So arrange, can realize the sealing between valve body and gland nut, guarantee the excellent sealing of valve pocket.
Further, be provided with on described valve body for valve rod and extend the valve rod hole of valve body, be provided with Packing seat and filler in described valve rod hole, described filler surrounds and is pressed on described valve rod on every side for the sealing between valve rod and valve body; Be provided with Gland on described filler, described Gland and described valve rod hole are slidably matched.
So arrange, can guarantee the excellent sealing of valve body and valve pocket.
Further, described Gland is fixedly connected with valve body by screw.
So arrange, can make the structure of ball valve more rationally, simply.
Further, be provided with position limit pin, spacing shim and circlip for shaft on described Gland, described valve rod is connected with handle with circlip for shaft through spacing shim.
So arrange, can provide limit function for the motion of valve rod, guarantee the working properly of ball valve.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
The structural drawing that Fig. 1 is manual ball valve described in the utility model;
In figure, the implication of each label is as follows:
Valve body 1, gland nut 2, O type circle 3, spheroid 4, valve seat 5, valve rod 6, Packing seat 7, filler 8, handle 9, Gland 10, position limit pin 11, spacing shim 12, circlip for shaft 13, screw 14.
Embodiment
As shown in Figure 1, the utility model provides a kind of manual ball valve, comprises valve body 1, spheroid 4, valve seat 5, valve rod 6 and handle 9, and an end of described valve rod 6 is fixedly connected with spheroid 4, and the other end is fixedly connected with handle 9; It is characterized in that, a side of described valve body 1 is provided with the first fluid through hole, and opposite side is provided with tapped hole, screws on described tapped hole a gland nut 2 is installed, and on described gland nut 2, is provided with the second fluid through hole; The periphery of described gland nut 2 also is provided with one for sealing the O type circle 3 of valve pocket.Form a valve pocket between valve body 1 and gland nut 2, be provided with spheroid 4 in described valve pocket, valve body 1 be provided with valve seat 5 with spheroid 4 places of matching on gland nut 2.The utility model adopts gland nut 2 to replace a traditional side valve body, thereby has greatly shortened the structure length of this valve, has enlarged the using scope of ball valve.
Be provided with on described valve body 1 for valve rod 6 and extend the valve rod hole of valve body 1, be provided with Packing seat 7 and filler 8 in described valve rod hole, described filler 8 surrounds and is pressed on described valve rod 6 on every side for the sealing of 1 of valve rod 6 and valve body; Be provided with Gland 10 on described filler 8, described Gland 10 is slidably matched with described valve rod hole.Described Gland 10 is fixedly connected with valve body 1 by screw 14.Be provided with position limit pin 11, spacing shim 12 and circlip for shaft 13 on described Gland 10.Be provided with position limit pin 11, spacing shim 12 and circlip for shaft 13 on described Gland 10; described valve rod 6 is connected with handle 9 with circlip for shaft 13 through spacing shim 12; move to while contacting with position limit pin 11 at valve rod 6, can't continue to move down, thereby well protect ball valve.
The utility model not only is confined to above-mentioned embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple embodiment to implement the utility model; therefore; every employing project organization of the present utility model and thinking; do some simple designs that change or change, all fall into the scope of the utility model protection.
