Abstract
A butterfly valve comprises a valve body, a valve seat, a valve plate and a valve shaft. The valve plate is fixed in the valve seat, and the valve shaft penetrates the valve seat and the valve plate and is connected with the valve body. The butterfly valve is characterized in that the valve seat is separated from the valve body, the section of the valve seat is of a C-shaped structure, a double-piece spring is arranged at each of the upper end and the lower end of the outer side of the valve seat, a filler is arranged at a joint of the valve body and the valve shaft, a valve plug is arranged at the bottom end of the valve body, and the valve shaft penetrates the bottom end of the valve body and is connected with the valve plug. The butterfly valve has the advantages that the double-piece springs are arranged at the upper end and the lower end of the outer side of the valve and squeeze the valve seat when the valve is worn, so that airtightness of the valve is improved; the valve plug is arranged at the bottom end of the valve body, and the valve shaft penetrates the bottom end of the valve body and is connected with the valve plug, so that convenience is brought to replacement of the valve plate, and maintenance efficiency is improved.
Description
Technical field
The utility model relates to valve field, particularly a kind of butterfly valve.
Background technique
The valve body bottom of the butterfly valve that prior art scheme is produced is that enclosed construction, valve seat and valve body are fixed.Want to change valve plate and just valve body need to be taken apart, then extract valve shaft out, and valve seat is fixed on valve body, if the valve that the prooving of valve seat just must be pulled down whole valve or more renew.Meanwhile, because two ends up and down and the prooving of valve seat of the valve plate of butterfly valve are serious, after long-time use, there will be airtight not tight problem, need to change valve plate or valve seat.Not only inefficiency, and waste resource.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of butterfly valve.Specific design scheme is:
A kind of butterfly valve, comprise valve body, valve seat, valve plate, valve shaft, described valve plate is fixed in described valve seat, described valve shaft runs through described valve seat, valve plate and is connected with described valve body, it is characterized in that, described valve seat is separated with valve body, and the tangent plane of described valve seat is " C " shape structure, the two ends up and down in described valve seat outside are equipped with biplate spring, the joint of described valve body and valve shaft is provided with packing, and the bottom of described valve body is provided with valve plug and described valve shaft runs through the bottom of described valve body and is connected with described valve plug.
Described valve body top is provided with opening/closing component, and described opening/closing component is connected with described valve shaft.
The quantity of described biplate spring is a plurality of.
The butterfly valve obtaining by above-mentioned design proposal of the present utility model, its beneficial effect is:
The two ends up and down in described valve seat outside are equipped with biplate spring, push valve seat when valve weares and teares, and improve valve seal.
The bottom of described valve body is provided with valve plug and described valve shaft runs through the bottom of described valve body and is connected with described valve plug, is convenient for changing valve plate, improves maintenance efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of butterfly valve described in the utility model;
Fig. 2 is the side-looking structural representation of butterfly valve described in the utility model;
In figure, 1, valve body; 2, valve seat; 3, valve plate; 4, valve shaft; 5, biplate spring; 6, packing; 7, valve plug; 8, opening/closing component.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural representation of butterfly valve described in the utility model, Fig. 2 is the side-looking structural representation of butterfly valve described in the utility model, as Fig. 1, shown in Fig. 2, a kind of butterfly valve, comprise valve body 1, valve seat 2, valve plate 3, valve shaft 4, described valve plate 3 is fixed in described valve seat 2, described valve shaft 4 runs through described valve seat 2, valve plate 3 is also connected with described valve body 1, described valve seat 2 is separated with valve body 1, and the tangent plane of described valve seat 2 is " C " shape structure, the two ends up and down in described valve seat 2 outsides are equipped with biplate spring 5, described valve body 1 is provided with packing 6 with the joint of valve shaft 4, the bottom of described valve body 1 is provided with valve plug 7 and described valve shaft 4 runs through the bottom of described valve body 1 and is connected with described valve plug 7.
Described valve body 1 top is provided with opening/closing component 8, and described opening/closing component 8 is connected with described valve shaft 4.
The quantity of described biplate spring 5 is a plurality of.
In the time of need to changing valve shaft 4, only need back out valve plug 7, then extract valve shaft 4 out and change, then tighten valve plug 7.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
