Abstract
The utility model provides a butterfly valve, including the valve body, the valve body comprises valve piece and connecting portion, is equipped with the through -hole in the valve piece, and the both ends of valve piece all are equipped with enclosure, and enclosure's inboard is equipped with the location dog, fixes a position the shape semicircular in shape of dog, and the number of location dog is four, and the number of the location dog of every enclosure inboard is two, location dog along the axis symmetric distribution of valve piece, and the location dog of valve piece axis both sides sets up for the cambered surface relatively. This butterfly valve changes the location dog into through the ring of the fender with the last whole circle of valve piece, has reduced blank weight, and the cost is reduced has improved production efficiency, and the product is also more pleasing to the eye.
Description
Technical field
This utility model belongs to valve processing and manufacturing field, particularly to a kind of butterfly valve.
Background technology
At present, fire-fighting butterfly valve valve block two ends prevent the position of pipe clamp movement be on valve block one piece casting out, whole circle
Baffle ring can lead to valve block blank weight increase and working (machining) efficiency low, and process after position often because process hair
Pierce and affect attractive in appearance.Therefore, need now a kind of butterfly valve not only saved material but also former using effect can be reached badly.
Utility model content
The utility model proposes a kind of butterfly valve, the baffle ring solving whole circle on valve block in prior art can lead to valve block blank
The problem that weight increases and working (machining) efficiency is low.
The technical solution of the utility model is realized in：A kind of butterfly valve, including valve body, described valve body is by valve block and company
Socket part forms, and is provided with through hole in described valve block, and the two ends of described valve block are equipped with enclosure, and the inner side of described enclosure is provided with positioning gear
Block, the shape semicircular in shape of described position block, the number of described position block is four.
As one preferred embodiment, the number of the described position block inside each described enclosure is two.
As one preferred embodiment, described position block is along the axisymmetrical distribution of described valve block.
As one preferred embodiment, the described position block of valve block axis both sides is oppositely arranged for cambered surface.
After employing technique scheme, the beneficial effects of the utility model are：By the baffle ring of circle whole on valve block is changed
For four position blocks, decrease blank weight, reduce cost, improve production efficiency, product is also more attractive in appearance.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before not paying creative labor
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the overall structure diagram of this utility model butterfly valve.
In figure, 1- valve block；2- connecting portion；3- enclosure；4- position block.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Embodiment：
As shown in figure 1, a kind of butterfly valve, including valve body, valve body is made up of valve block 1 and connecting portion 2, is provided with through hole in valve block 1,
The two ends of valve block 1 are equipped with enclosure 3, and the inner side of enclosure 3 is provided with position block 4, the shape semicircular in shape of position block 4, positioning
The number of block 4 is four, and the number of the position block 4 of each enclosure 3 inner side is two, and position block 4 is along the axis of valve block 1
Symmetrical, the position block 4 of valve block 1 axis both sides is oppositely arranged for cambered surface.By the baffle ring of circle whole on valve block is changed to four
Individual position block, decreases blank weight, reduces cost, improves production efficiency, and product is also more attractive in appearance.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model
Protection domain within.
