Abstract
The invention provides a top-mounted wedge-shaped lifting ball valve. The top-mounted wedge-shaped lifting ball valve comprises a main valve body, wherein wedge surfaces are arranged at two sides, corresponding to a flowing channel, in the main valve body; an inner valve body is arranged in the main valve body; a flowing channel in the inner valve body communicates with the flowing channel in the main valve body; wedge surfaces in match with the wedge surfaces of the main valve body are arranged at two sides of the inner valve body; the inner valve body is in sealing fit with the main valve body; a valve seat in which a ball body is positioned is arranged in the inner valve body, and the ball body is in sealing fit with the valve seat; the upper side of the ball body is in linkage fit with a valve rod; the valve rod passes through a valve cover to be in linkage fit with an operating mechanism. According to the top-mounted wedge-shaped lifting ball valve, the inner valve body and the ball body are in sealing fit to replace a valve element according to a wedge-shaped valve, and the wedge surfaces in the wedge shaped valve are extruded by the wedge surfaces at two sides of the inner valve body so as to achieve the sealing fit; meanwhile, the valve element can be conveniently replaced, and moreover, the residue accumulation can be avoided.
Description
Technical field
The present invention relates to a kind of ball valve, be specifically related to a kind of upper dress wedge-type lifting ball valve.
Background technique
Existing ball valve goes wrong in use, mostly need to carry out spheroid replacing, change spheroid then complex operation, need valve rod to remove successively in valve body, have a strong impact on replacing construction, reduce and change efficiency, adopt gate valve then easy between flashboard and valve body remaining residue, of long duration, the sealability of valve can be affected, need to carry out disassembly, cleaning.
Summary of the invention
In order to solve above deficiency, the invention provides a kind of upper dress wedge-type lifting ball valve.
The invention provides: one fills wedge-type lifting ball valve, it comprises main valve body, described main valve body, in main valve body, the both sides of corresponding runner are provided with wedge surface, in described main valve body, inner valve body is set, the runner of described inner valve body and the flow passage of main valve body, described inner valve body both sides are provided with the wedge surface matched with the wedge surface of main valve body, described inner valve body and main valve body form and are sealed and matched, in described inner valve body, valve seat is set, spheroid is placed in described valve seat, described spheroid coordinates with valve base sealing, upside and the valve rod of described spheroid are linked, described valve rod is linked through valve gap and operating device, described valve gap is connected with main valve body and inner valve body bolt respectively.
The upper and lower end face of described inner valve body both sides is respectively equipped with Sealing.
The valve seat of described inner valve body and main valve body is sealed and matched firmly.
Described operating device is operating grip.
Described main valve body two ends arrange flange.
Described valve rod is each passed through the first valve gap and the second valve gap and operating device and is linked, and described first valve gap is connected with main valve body bolt, and described second valve gap is connected with inner valve body bolt.
Runner eccentric setting on described spheroid.
Spool, on the basis of wedge valve, is replaced to being sealed and matched of inner valve body and spheroid by the present invention, and the wedge surface utilizing the wedge surface of inner valve body both sides to extrude wedge valve inside realizes being sealed and matched, and changes spool convenient simultaneously, and can not cause the phenomenon that residue is piled up.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As shown in Figure 1, the invention discloses a kind of upper dress wedge-type lifting ball valve, it comprises main valve body 2, in main valve body 1, the both sides of corresponding runner are provided with wedge surface, in described main valve body 1, inner valve body 2 is set, the runner of described inner valve body 2 and the flow passage of main valve body 1, described inner valve body 2 both sides are provided with the wedge surface matched with the wedge surface of main valve body 1, described inner valve body 2 and main valve body 1 form and are sealed and matched, in described inner valve body 2, valve seat 3 is set, spheroid 4 is placed in described valve seat 3, described spheroid 4 is sealed and matched with valve seat 3, upside and the valve rod 6 of described spheroid 4 are linked, described valve rod 6 is linked through valve gap and operating device, described valve gap 7 is connected with main valve body and inner valve body bolt respectively.Described valve rod is each passed through the first valve gap and the second valve gap and operating device and is linked, and described first valve gap is connected with main valve body bolt, and described second valve gap is connected with inner valve body bolt.Described main valve body two ends arrange flange, fixing with on pipeline by flange.
The present invention is when needs are changed, only need the disassembling bolts be directly connected with main valve body by the first valve gap, directly whole for inner valve body 2 extracting is changed, reduce the difficulty changed, the extruding of wedge surface simultaneously coordinates, and can ensure inner valve body 2 and the sealing effect in main valve body 1, when downward firmly compressing inner valve body, the wedge surface of inner valve body can oppress the wedge surface of main valve body, improves its sealing.
Described valve gap is connected with main valve body bolt, is also fixedly connected with ball valve by bolt inside it, only needs the bolt be connected with main valve body to remove, just whole inner valve body can be extracted, and all dismounting then can carry out the replacing of spheroid, convenient and swift.
The upper and lower end face of described inner valve body both sides is respectively equipped with Sealing 5, and when inner valve body is subject to downward power, it can extrude the wedge surface of both sides, squeeze sealing member, is placed on it lower leakage.
The valve seat of described inner valve body and main valve body is sealed and matched firmly, adopts firmly to seal to avoid its bottom leakage between the bottom of inner valve body and the valve seat of main valve body.
Described operating device is operating grip, spheroid can be driven to rotate thus realize the effect of flow channel switch, other mode of operation also can be adopted to operate by pulling operating grip.
Embodiment should not be considered as limitation of the present invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
