The novel switch ball valve is characterized in that the valve body is formed by the main body with the inlet and the valve body joint with the outlet; the ball valve is arranged in the main body; two ends of the ball valve body are respectively provided with an inlet and an outlet; the ball valve is connected with the switch handle and is mounted on the valve body; the switch handle can drive the ball valve to rotate to open or close the valve; and the slant through hole is arranged on a radial section of the ball valve.
Description
Technical field
The utility model relates to a kind of Ball valve, particularly a kind of novel switched Ball valve.
Background technique
Switch ball valve is at present modal a kind of for opening or close the pipeline valve of pipeline fluid; Its structure majority comprises the valve body with valve ball, and the two ends of valve body respectively arrange 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 arranged in the valve rod hole on valve body top, between valve rod and valve rod hole, is provided with " O " RunddichtringO; Valve rod is integrally connected 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 residual fluid when the throttle down outlet port of often being everlasting, and like this, can increase loine pressure and affects the working efficiency of pipeline, can affect the working life of causing because of loine pressure again.Especially in some test occasion, by ball valve, control the circulation of test fluid flow, after test completed, ball valve was closed, and had cut off the supply of fluid, now in the pipeline after valve, always have residual fluid, such one is the pressure that can increase pipeline, affects the life-span, the 2nd, and may be when the dismounting test product, due to the sudden outburst of fluid, there is certain danger; If, by other device, get rid of fluid residual in pipeline, but can increase cost so again, also likely increase leakage point.
Summary of the invention
According to problem set forth above, the utility model is in order to overcome at present existing valvular shortcoming, a kind of better novel switched Ball valve of Security that has to be provided.By main body (1), valve ball (4), valve rod (5), screw (6), seal ring (7), drain boles (8), O RunddichtringO (9), valve body joint (11), import (12), outlet (13) oblique through hole (14), switch knob (15), formed, it is characterized in that described valve body is to be formed by the main body with described import and the valve body splice combinations with described outlet, described ball valve is configured in described main body; The valve body two ends of ball valve are respectively arranged with import and outlet, and this ball valve connects a switch knob, and is arranged on valve body, can drive again described ball valve and rotate and open or close described valve, on the radially section of described ball valve, are 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.Due to the structure that adopts above drain boles to be connected with valve outlet, when throttle down, the residual fluid in outlet port is just to discharge from oblique through hole; Like this, in pipeline, can not cause counterpressure and affect the working efficiency of pipeline, thereby can improve Security and the working life of use.Described main body can adopt and be threaded with described valve body joint; The technique simple and feasible.The both sides of described ball valve can respectively arrange a seal ring respectively and between described main body, described valve body joint; Its effect is the sealability guaranteed between described valve body and ball valve.Described ball valve top can connect described switch knob by a valve rod, and this valve rod is arranged in the valve rod hole on described main body top; Open valve or throttle down to realize the master cock handle.Between described valve rod and valve rod hole, can be provided with " O " RunddichtringO; Guarantee valve rod and valve body and between can not leak.On described oblique through hole and ball valve, through hole forms 90 ± 10 degree angles.Preferably 90 spend.The utility model is due to the structure that has adopted drain boles to be connected with valve outlet, and its advantage is to have very good working life and Security compared with prior art; Simple and practical, easily manufacture and produce, be particularly suitable in testing apparatus the switch ball valve field with pressure relief device of applying.
The accompanying drawing explanation
Fig. 1 is opening state structural drawing of the present utility model;
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show a kind of switch ball valve with pressure relief device that can be used for testing apparatus of the utility model, and it comprises the main body 1 with valve ball 4, and an end of main body 1 is provided with import 12, and the other end of main body 1 connects the valve body joint 11 of a band outlet 13.Between main body 1 and valve body joint 11, adopt and be threaded.The both sides of switching ball 4 are provided with seal ring 7 with valve body import 12 places, valve body joint outlet 13 places respectively; To guarantee the sealability between valve body and ball valve.Switching ball 4 tops connect a switch knob 15 by valve rod 5; Valve rod 5 is arranged in the valve rod hole on valve body 1 top, between valve rod 5 and valve rod hole, is provided with " O " RunddichtringO 9; Valve rod 5 is integrally connected by screw 6 and 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.On the radially section of ball valve 4, be provided with oblique through hole 14; On oblique through hole 14 and ball valve, through hole forms an angle of 90 degrees degree, 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, the residual fluid that exports 13 places with can be by drain boles 8 with oblique through hole 14 from valve body 1, flowing out, like this, be unlikely the working efficiency that can increase loine pressure and affect pipeline, can not affect the working life of causing because of loine pressure again.
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 and all do not communicated with valve, as shown in Figure 1, without fluid, flows out in drain boles.When ball valve was in closed condition, the import 12 before and after ball valve was cut off to outlet 13 passages, and fluid no longer circulates.Now, on valve body, drain boles 8 communicates with outlet 13 places of valve by the oblique through hole 14 on ball valve, the residual fluid at valve outlet place is discharged to beyond system by the drain boles 8 on oblique through hole 14 and valve body on 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, after ball valve, the fluid of pipeline can flow out the purpose that reaches release by the drain boles of ball valve.After this valve also can be used for other valves, pipeline had the occasion of unloading pressure request.
