Description
Technical field
The utility model relates to a kind of pipeline valve field, especially relates to a kind of switching ball door that pipeline is used that is used to open or close.
Background technique
The switching ball door is present modal a kind of pipeline valve that is used for opening or closing the pipeline fluid; Its structure majority comprises the valve body of a band valve ball, and two ends of valve body respectively is provided with an import and outlet, and the both sides of valve ball are provided with seal ring with valve body import, valve outlet place respectively.
Switch valve ball top connects a switch knob by valve rod; Valve rod is installed in the valve rod hole on valve body top, is provided with " O " RunddichtringO between valve rod and the valve rod hole; Valve rod connects one by the screw switch knob, and the master cock handle can realize that valve ball rotates in valve body, thus Open valve or throttle down easily.
Above-mentioned common switching ball structure has remaining fluid when the throttle down outlet port of being everlasting often, like this, can increase loine pressure and influences the working efficiency of pipeline, can influence the working life of causing because of loine pressure again.
Especially in some test occasion, control the circulation of test fluid flow by ball valve, after test was finished, ball valve was closed, and had cut off the supply of fluid, always have remaining fluid in the pipeline behind the valve at this moment, such one is the pressure that can increase pipeline, influences the life-span, the 2nd, and may be when the dismounting test product, because there is certain danger in the unexpected release of fluid; If, get rid of remaining fluid in the pipeline by other device, but can increase cost so again, also might increase leakage point.
The model utility content
Technical problem to be solved in the utility model is exactly to provide a kind of better switching ball door of Security that has at the present situation of above-mentioned prior art.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be: a kind of switching ball door, the valve body that comprises a dribbling valve, this two ends of valve body is respectively arranged with import and outlet, this ball valve connects a switch knob, and be installed on the described valve body, can drive described ball valve again and rotate and open or close described valve, it is characterized in that: described valve body is by forming with the main body of described import and valve body splice combinations with described outlet, and described ball valve is configured in the described main body; The radially section of described ball valve is provided with oblique through hole; The bottom of described main body is provided with drain boles; Under the ball valve closed condition, an end of this oblique through hole is corresponding with the position of described drain boles, and the other end of this oblique through hole is connected with described outlet.
Because the structure that adopts above drain boles to be connected with valve outlet, when throttle down, the remaining fluid in the outlet port just is to discharge from oblique through hole; Like this, can not cause counterpressure in the pipeline and influence the working efficiency of pipeline, thereby can improve the Security and the working life of use.
Described main body can adopt with described valve body joint and be threaded; The technology simple and feasible.
The both sides of described ball valve can respectively be provided with a seal ring respectively and between the described main body, described valve body joint; Its effect is the sealability that guarantees between described valve body and the ball valve.
Described ball valve top can connect described switch knob by a valve rod, and this valve rod is installed in the valve rod hole on described main body top; Open valve or throttle down to realize the master cock handle.
Can be provided with " O " RunddichtringO between described valve rod and the valve rod hole; Guarantee valve rod and valve body and between can not leak.
Through hole constitutes 90 ± 10 degree angles on described oblique through hole and the ball valve.Preferred 90 degree.
The utility model is owing to the structure that has adopted drain boles to be connected with valve outlet, and compared with prior art, its advantage is to have very good working life and Security; Simple and practical, make easily and produce, be suitable for using in the testing apparatus switching ball door field of band pressure relief device especially.
Description of drawings
Fig. 1 is an opening state structural drawing of the present utility model;
Fig. 2 is a closed condition structural drawing of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show a kind of switching ball door that can be used for the band pressure relief device of testing apparatus of the utility model, and it comprises the main body 1 of being with valve ball 4, and an end of main body 1 is provided with import 12, and the valve body joint 11 of mouth 13 is taken in the other end connection one of main body 1 out of.Adopt between main body 1 and the valve body joint 11 and be threaded.
The both sides of switching ball 4 export 13 places with valve body import 12 places, valve body joint respectively and are provided with seal ring 7; To guarantee the sealability between valve body and the ball valve.
Switching ball 4 tops connect a switch knob 15 by valve rod 5; Valve rod 5 is installed in the valve rod hole on valve body 1 top, is provided with " O " RunddichtringO 9 between valve rod 5 and the valve rod hole; Valve rod 5 is connected one by screw 6 with switch knob 15, and master cock handle 15 can realize that ball valve 4 rotates in valve body 1, and Open valve or throttle down.
The radially section of ball valve 4 is provided with oblique through hole 14; Through hole constitutes an angle of 90 degrees degree on oblique through hole 14 and the ball valve, and valve body 1 bottom is provided with drain boles 8; Under ball valve 4 closed conditions, this oblique through hole 14 is corresponding with the position of drain boles 8; The other end of this oblique through hole 14 is connected with the outlet 13 of valve body joint.
When valve closing, export the remaining fluid at 13 places and can pass through drain boles 8 and from valve body 1, flow out with oblique through hole 14, like this, be unlikely the working efficiency that can increase loine pressure and influence pipeline, can not influence the working life of causing again because of loine pressure.
The utility model working procedure is such:
When ball valve was in opening state, fluid can pass through ball valve to outlet 13 smoothly from the import 12 of valve body 1, and drain boles 8 is imported and exported with valve and all do not communicated, and as shown in Figure 1, no fluid flows out in the drain boles.
When ball valve was in closed condition, the import 12 before and after the ball valve was cut off to outlet 13 passages, and fluid no longer circulates.At this moment, drain boles 8 communicates with outlet 13 places of valve by the oblique through hole 14 on the ball valve on the valve body, the residual fluid at valve outlet place is discharged to beyond the system by the drain boles 8 on oblique through hole 14 and the valve body on the valve ball, as shown in Figure 2, guarantee that the follow-up pipeline of valve body communicates with atmosphere, reaches the purpose of release.
In order to address this problem, design a kind of ball valve with pressure relief device, make when valve is opened, fluid can normally pass through ball valve, carry out every test, and when ball valve was closed, the fluid of pipeline can flow out the purpose that reaches release by the drain boles of ball valve behind the ball valve.Pipeline had the occasion of unloading pressure request after this valve also can be used for other valves.
