Compared with the prior art, the utility model, through the setting in first limbers and second limbers, on the basis that does not influence the butterfly valve and close the effect, increased the latus rectum area of valve body, increased the latus rectum coefficient of butterfly valve, reduced the resistance of valve body for the operation energy consumption of butterfly valve obtains effectively reducing, has played energy-conserving effect, has reduced the operation cost.
Description
Technical Field
The utility model belongs to the technical field of the butterfly valve, concretely relates to butterfly valve that possesses big latus rectum coefficient.
Background
A butterfly valve is a commonly used fluid flow control valve, as shown in fig. 1, the existing butterfly valve includes a valve body 1, a sealing ring 2, a valve shaft 5, a valve plate 3, a valve rod 4 and a handle 6, the valve plate 3 in fig. 1 is in an open state, a fluid medium flows through the valve body 1 through a fluid passage 11 of the valve body 1, but in the through-flow process, the valve plate 3 and the valve rod 4 in the fluid passage 11 block part of the fluid, so that the through-diameter coefficient of the butterfly valve can be reduced, the pipeline resistance is increased, the butterfly valve is not beneficial to energy-saving operation, and the energy consumption is high.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the butterfly valve with the large drift diameter coefficient is provided, the drift diameter coefficient of the butterfly valve can be improved, the pipeline resistance is reduced, and the operation energy consumption is reduced.
The technical scheme is as follows: in order to achieve the above object, the utility model provides a butterfly valve that possesses big latus rectum coefficient, including valve body, valve shaft, valve plate, valve rod, sealing washer and handle, a plurality of longitudinal arrangement's first limbers have been seted up to the side of valve plate, a plurality of longitudinal arrangement's second limbers have all been seted up to the both sides portion that the valve rod is located the valve plate.
Furthermore, first limbers level sets up on the valve plate, and the first limbers of horizontally can be favorable to the water to pass through more, reduction latus rectum coefficient that can be better.
Further, the first water through holes are longitudinally arranged on the valve plate at equal intervals.
Furthermore, the second through hole level sets up on the valve rod, and the horizontally second through hole can be favorable to the water to pass through more, reduction latus rectum coefficient that can be better.
Furthermore, the second water through holes are longitudinally arranged on the valve rod at equal intervals.
The design principle of the utility model is that: the first water through hole and the second water through hole are respectively formed in the side face of the valve plate and the two side portions of the valve rod, when the butterfly valve is opened, the butterfly valve can just meet the water flow direction, and partial water flow can flow through the first water through hole and the second water through hole, so that the drift diameter area of the valve body is increased, the drift diameter coefficient of the butterfly valve is increased, and the resistance of the valve body is reduced.
In addition, the first water through hole and the second water through hole have the water passing function only when the valve plate is in the open state, when the valve plate is in the closed state, the first water through hole is sealed by the sealing ring, the direction of the second water through hole is consistent with that of the valve plate, medium water cannot penetrate through the valve plate through the second water through hole, and therefore the water retaining effect of the butterfly valve when the butterfly valve is closed cannot be influenced by the first water through hole and the second water through hole.
Has the advantages that: compared with the prior art, the utility model, through the setting in first limbers and second limbers, on the basis that does not influence the butterfly valve and close the effect, increased the latus rectum area of valve body, increased the latus rectum coefficient of butterfly valve, reduced the resistance of valve body for the operation energy consumption of butterfly valve obtains effectively reducing, has played energy-conserving effect, has reduced the operation cost.

Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
As shown in fig. 2-5, the utility model provides a butterfly valve that possesses big latus rectum coefficient, including valve body 1, valve shaft 5, valve plate 3, valve rod 4, sealing washer 2 and handle 6, nine vertical equidistant first limbers 7 of arranging are seted up to the side of valve plate 3, and ten vertical equidistant second limbers 8 of arranging are all seted up to the both sides portion that valve rod 4 is located valve plate 3, and nine first limbers 7 are all horizontal to be set up on valve plate 3, and two sets of ten second limbers 8 are horizontal respectively to be set up in the both sides of valve plate 3.
As shown in fig. 2, when the butterfly valve is in the open state, the valve plate 3 rotates 90 degrees from the closed state, at this time, the water flow paths of the first water passage hole 7 and the second water passage hole 8 are consistent with the water flow direction, most of the fluid in the fluid passage 11 of the valve body 1 will flow through both sides of the valve plate 3 and the valve rod 4, but part of the fluid will pass through the valve plate 3 and the valve rod 4 from the first water passage hole 7 and the second water passage hole 8, respectively, and finally flows out of the valve body 1 together with other fluid confluence.
Through actual detection, the drift diameter area of the valve body 1 can be increased by more than 10%, the drift diameter coefficient of the butterfly valve is increased, the resistance of the valve body is reduced, finally, the operation energy consumption of the butterfly valve is effectively reduced, the energy-saving effect is achieved, and the operation cost is reduced.
As shown in fig. 3, when the butterfly valve is in a closed state, the first water through hole 7 is hidden, the second water through holes 8 are respectively located at two sides of the valve plate 3, and the first water through hole 7 and the second water through hole 8 do not affect the flow blocking effect of the butterfly valve because the flow blocking function of the valve plate 3 is eliminated.
