Part of the body, is installed on the butterfly valve body, the inside seal groove that is equipped with of clamp plate, sealing washer are located the seal groove, the clamp plate is fixed through screw locking with the butterfly valve body, the protruding ring flange that is equipped with of flexible outside of tubes side, ring flange and butterfly valve position in the flexible relative both ends of pipe, flexible outside of tubes side still is equipped with the lug with flexible pipe integrated into one piece, the lug is located between clamp plate and the ring flange, spacing flexible butterfly valve also include with the limit screw of lug and butterfly valve body coupling and with a plurality of stop nut of limit screw complex, can prevent that the expansion pipe from drawing takes off, guarantees the security of operation of pipeline, flexible pipe and lug integrated into one piece, simple structure need not extra installation, saves the cost, and the whole quality of flexible pipe is little, is favorable to spacing flexible butterfly valve's work.
Description
Technical field
The utility model relates to valve, particularly a kind of limit telescopic butterfly valve.
Background technique
Butterfly valve is a kind of conventional valve, open-shut device is butterfly plate, butterfly plate and valve shaft rotate, reach the object of opening and closing, flexible butterfly valve not only has outside the effect of butterfly valve, in pipeline, also there is certain extending amount, can be convenient to install and play compensating action because of expanding with heat and contract with cold of pipeline, prevent pipeline to be pulled off.At present, common flexible butterfly valve is design like this, and as shown in Figure 1, pressing plate 4 ' is set on telescopic pipe 2 ', seal ring 3 ' is put into the groove of pressing plate 4 ', is connected and clamping platen 4 ' by pressing plate 4 ' with screw 5 ' with valve body 1 '.But when pipeline rising-heat contracting-cold, telescopic pipe 2 ' also deformation can occur, probably can depart from valve body during telescopic pipe work, flexible butterfly valve be lost efficacy, affects the security of operation of pipeline.
Given this, be necessary that designing a kind of limit telescopic butterfly valve solves the problems referred to above.
Model utility content
The technical problems to be solved in the utility model is: provide the limit telescopic that a kind of structure is simple, quality is little and prevent telescopic pipe from pulling butterfly valve.
For achieving the above object, the utility model provides following technological scheme: a kind of limit telescopic butterfly valve, comprise butterfly type valve, be arranged on the telescopic pipe on butterfly type valve and the seal ring be set in outside telescopic pipe and pressing plate, described pressing plate inside is provided with seal groove, seal ring is positioned at seal groove, described pressing plate and butterfly type valve are fixed by screw lock, flange plate is convexly equipped with outside described telescopic pipe, described flange plate and butterfly type valve are positioned at the relative two ends of telescopic pipe, integrated lug is also provided with telescopic pipe outside described telescopic pipe, described lug is between pressing plate and flange plate, described limit telescopic butterfly valve also comprises the Limit screw be connected with butterfly type valve by lug and the some stop nuts coordinated with Limit screw.
Further, be convexly equipped with valve flange dish outside described butterfly type valve, described Limit screw connects valve body flange plate and lug, and described stop nut is arranged on the both sides of lug, and described stop nut is also arranged on valve flange dish and deviates from the side of lug.
Further, described valve flange dish reciprocates relative to Limit screw.
Prior art is compared, and the utility model at least has the following advantages: can prevent telescopic pipe from pulling, and ensures the security of operation of pipeline; Telescopic pipe and lug one-body molded, structure is simple, without the need to extra installation, saves cost; And telescopic pipe total quality is little, be conducive to the work of limit telescopic butterfly valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flexible butterfly valve of prior art.
Fig. 2 is the structural representation of the utility model limit telescopic butterfly valve.
Fig. 3 is the partial enlarged drawing of the part A shown in Fig. 2.
Embodiment
Structure and the model utility content of the utility model limit telescopic butterfly valve are described below in conjunction with Fig. 2.
A kind of limit telescopic butterfly valve, comprises butterfly type valve 1, the telescopic pipe 2 be arranged on butterfly type valve 1, the screw 5 that is set in seal ring 3 outside telescopic pipe 2 and pressing plate 4 and pressing plate 4 and butterfly type valve 1 is locked.
Described butterfly type valve 1 is provided with the host cavity installed for telescopic pipe 2.The valve flange dish 6 be connected with telescopic pipe 2 is convexly equipped with outside described butterfly type valve 1.
The flange plate 7 of connecting tube is convexly equipped with outside described telescopic pipe 2.Described flange plate 7 and butterfly type valve 1 are positioned at the relative two ends of telescopic pipe 2.Integrated lug 8 is also provided with telescopic pipe 2 outside described telescopic pipe 2.Described lug 8 is between pressing plate 4 and flange plate 7.
Described pressing plate 4 inside is provided with seal groove 9.Seal ring 3 is positioned at seal groove 9.
Described limit telescopic butterfly valve also comprises the Limit screw 10 be connected with butterfly type valve 1 by lug 8 and the some stop nuts 11 coordinated with Limit screw 10.Described Limit screw 10 connects valve body flange plate 6 and lug 8.Described stop nut 11 is arranged on the both sides of lug 8.Described stop nut 11 is also arranged on valve flange dish 6 and deviates from the side of lug 8.Described valve flange dish 6 reciprocates relative to Limit screw 10.
Limit telescopic butterfly valve of the present utility model regulates the extending amount simple and fast of telescopic pipe, and effectively prevents telescopic pipe from departing from butterfly type valve, ensure that the security of operation of pipeline.On telescopic pipe, one-body molded lug is used for spacing, and this spline structure is simple, and without the need to extra installation, component are few, and total quality is little, are conducive to the application of flexible butterfly valve.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should do not limited with this.Namely every simple equivalence change done according to the utility model claims and description with modify, all should still belong in scope that the utility model patent contains.
