Background
The butterfly valve is also called flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline medium. The butterfly valve is simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving moment, simple and convenient to operate and rapid, and also has a good flow regulation function and a good sealing closing characteristic, is one of the fastest valve varieties developed in recent decades, and in daily use, the damage of the valve mainly comprises internal leakage and external leakage, and the caused reasons are that besides the quality of the valve, cavitation erosion or vibration caused by suddenly intensified impact on a valve plate of fluid flow velocity is mostly caused, so that the sealing is not tight, and therefore, a high-sealing butterfly valve with a damping function needs to be developed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high leakproofness butterfly valve with shock-absorbing function has solved the poor problem of traditional butterfly valve leakproofness.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a high leakproofness butterfly valve with shock-absorbing function, including disk seat, the valve body on disk seat upper portion, valve body upper portion is equipped with the executor, executor one side is equipped with the hand wheel, the inside first case that is equipped with of valve body, first valve rod is worn to be equipped with at first case both ends, be equipped with elastic seal between valve body and the first case, valve body one side is equipped with discharge valve, first case is split type structure, including preceding valve plate and back valve plate, preceding valve plate all is equipped with a plurality of counter bores with the back valve plate, all be equipped with damping spring in the counter bore.
Furthermore, the front valve plate and the rear valve plate are of an embedded structure.
Further, the exhaust valve comprises a shell, a handle is arranged on the upper portion of the shell, a second valve rod penetrates through the handle, a second valve core is arranged on the lower portion of the second valve rod, and an exhaust port is formed in one side of the shell.
The technical effects of the utility model:
compared with the prior art, the utility model relates to a high leakproofness butterfly valve with shock-absorbing function, through setting up discharge valve, when the valve is inside because gas accumulation causes cavitation, can in time exhaust, reduce the valve vibrations, through setting up preceding valve plate, back valve plate and damping spring, when the fluid velocity of flow sharply increases in the valve, the impact force that liquid produced is offset by the deformation that the damping spring that preceding valve plate and back valve plate set up produced, and simple structure antidetonation is effectual.

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described with reference to the drawings attached to the specification of the present invention.
Example (b):
as shown in fig. 1-3, the high-sealing butterfly valve with a shock absorption function according to this embodiment includes a valve seat 1, a valve body 2 on the upper portion of the valve seat 1, an actuator 7 is disposed on the upper portion of the valve body 2, a hand wheel 8 is disposed on one side of the actuator 7, a first valve element 5 is disposed inside the valve body 2, a first valve rod 4 penetrates through two ends of the first valve element 5, the actuator 8 is rotated to drive the first valve rod 4 to rotate the first valve element 5, and the butterfly valve is opened and closed, an elastic seal 3 is disposed between the valve body 2 and the first valve element 5, when the valve is closed, the first valve element 5 is tightly pressed against the elastic seal 3, so as to achieve high sealing in the circumferential direction, an exhaust valve 6 is disposed on one side of the valve body 2, and gas exists in the valve body 2, so that the exhaust valve 6 is opened to exhaust gas timely when cavitation erosion occurs, so that vibration of the valve body 2 can be reduced, the first valve element 5 is of a split structure including a front valve plate 54 and a rear valve plate 53, the front valve plate 54 and the rear valve plate 53, each of which are disposed with a plurality of counter bores 51, and damping springs 52 are disposed in the counter bores 51, and when flow rate of liquid in the valve plate 2 increases, so that the flow rate of liquid is increased, and the inner portion of the inner portion 54 and the inner portion of the valve plate 53 is offset the inner portion of the damping spring 52.
The front valve plate 54 and the rear valve plate 53 are of an embedded structure.
The exhaust valve 6 comprises a shell 65, the upper part of the shell 65 is a handle 61, a second valve rod 62 is arranged on the handle 61 in a penetrating mode, a second valve core 63 is arranged on the lower part of the second valve rod 62, and an exhaust port 64 is arranged on one side of the shell.
The utility model discloses a concrete implementation:
when the butterfly valve generates vibration due to cavitation erosion, firstly, the handle 61 of the exhaust valve 6 is rotated, the handle 61 drives the second valve rod 62 to lift the second valve core 63, and air flow is exhausted through the exhaust port 64 formed in the shell 65; when the butterfly valve vibrates due to the extremely high flow rate of liquid, the liquid impacts the first valve core 5, the front valve plate 54 and the rear valve plate 53 can generate relative displacement, the damping spring 52 deforms, and the generated elastic force offsets the impact force generated by the liquid.
The above embodiments are only specific cases of the present invention, and the protection scope of the present invention includes but is not limited to the forms and styles of the above embodiments, and any suitable changes or modifications made thereto by those skilled in the art according to the claims of the present invention shall fall within the protection scope of the present invention.
