Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of exhaust valves, and particularly relates to a buffer type exhaust valve. Background Art
[0002] During the use of existing exhaust valves, when most floating balls sink, they will directly contact and collide with the valve body or its components. Since most floating balls are made of metal, the collision will inevitably damage the floating balls. Content of the Utility Model
[0003] The purpose of the utility model is to provide a buffer type exhaust valve aiming at the defects and deficiencies of the prior art.
[0004] To achieve the above purpose, the technical scheme adopted by the utility model is: a buffer type exhaust valve, which includes a valve cover, a valve body, a ball basket and a floating ball. The valve cover is arranged on the top of the valve body, and an air inlet and outlet is opened on the valve cover; the ball basket is located inside the valve body, and the lower part of the ball basket is hemispherical; the upper part of the ball basket is open, upper through holes are opened in the upper part of the side wall of the ball basket, middle through holes are opened in the middle of the ball basket, lower through holes are opened at the bottom of the ball basket, and the floating ball is arranged inside the ball basket; the innovation lies in that: a vertical rod is arranged through the lower through hole, a guide cylinder is sleeved outside the vertical rod, a plurality of connecting rods are arranged outside the guide cylinder and fixedly connected with the bottom of the ball basket, a sealing plug is arranged at the top of the vertical rod, the sealing plug is in clearance fit with the lower through hole, a supporting plate is arranged at the top of the sealing plug, the supporting plate is attached to the outside of the floating ball, and a small floating ball is arranged at the bottom of the vertical rod.
[0005] Further, a filter screen is arranged on the air inlet and outlet.
[0006] Further, a buffer spring is sleeved on the vertical rod, and the bottom of the buffer spring is fixedly connected with the top of the wire cylinder.
[0007] After adopting the above structure, the beneficial effect of the utility model is:
[0008] By arranging the vertical rod, the supporting plate, the small floating ball and the buffer spring, the utility model can buffer the sinking of the floating ball, avoid the floating ball from contacting and colliding with the valve body, and thus protect the floating ball.

[0011] 1 valve cover, 11 air inlet and outlet, 2 valve body, 3 ball basket, 31 upper through hole, 32 middle through hole, 33 lower through hole, 4 floating ball, 5 vertical rod, 6 guide cylinder, 7 sealing plug, 8 supporting plate, 9 filter screen, 10 buffer spring. Detailed implementation manners
[0012] The present utility model will be further described below in conjunction with the accompanying drawings.
[0013] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0014] Refer to Figure 1 , a buffer type exhaust valve, which includes a valve cover 1, a valve body 2, a ball basket 3 and a floating ball 4. The valve cover 1 is arranged on the top of the valve body 2, and an air inlet and outlet 11 is opened on the valve cover 1; the ball basket 3 is located inside the valve body 2, and the lower part of the ball basket 3 is hemispherical; the upper part of the ball basket 3 is open, an upper through hole 31 is opened in the upper part of the side wall of the ball basket, a middle through hole 32 is opened in the middle of the ball basket, and a lower through hole 33 is opened at the bottom of the ball basket. The floating ball 4 is arranged inside the ball basket 3; a vertical rod 5 is arranged through the lower through hole 33, a guide cylinder 6 is sleeved outside the vertical rod 5, a plurality of connecting rods are arranged outside the guide cylinder 6 and fixedly connected with the bottom of the ball basket 3, a sealing plug 7 is arranged at the top of the vertical rod 5, the sealing plug 7 is in clearance fit with the lower through hole 33, a supporting plate 8 is arranged at the top of the sealing plug 7, the supporting plate 8 is attached to the outside of the floating ball 4, and a small floating ball is arranged at the bottom of the vertical rod 5. Specifically, when negative pressure is formed in the pipeline and a large amount of air needs to be introduced, the floating ball 4 will be sucked down due to the action of pressure, and a large amount of gas will be sucked into the pipeline from the air inlet and outlet 11. At this time, the floating ball 4 drops due to the suction force, the floating ball 4 contacts the supporting plate 8, and at the same time, it is buffered under the action of the small floating ball and the supporting plate 8 to prevent the floating ball 4 from quickly colliding with the valve body 1, thereby protecting the floating ball; when the floating ball drops to the bottom of the ball basket 3, the sealing plug 7 closes the lower through hole 33; the vertical rod 5 moves up and down in the guide cylinder 6 to guide the sealing plug 7 and the supporting plate 8 to ensure that the sealing plug 7 can accurately drop into the lower through hole 33; the supporting plate 8 is preferably made as thin as possible to improve the fitting degree with the floating ball and the ball basket..
[0015] In this embodiment, a filter screen 9 is arranged on the air inlet and outlet 11. The protection net 9 can protect the exhaust valve and prevent impurities from entering.
[0016] In this embodiment, a buffer spring 10 is sleeved on the vertical rod 5, and the bottom of the buffer spring 10 is fixedly connected with the top of the wire cylinder 6. The buffer spring 10 can buffer the descent of the sealing plug 7 and also buffer the floating ball 4, thereby protecting the floating ball.
[0017] The above is only used to illustrate the technical solutions of the present utility model and not to limit them. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solutions of the present utility model.
