Dry type quick connector with eccentric structure

Abstract

A dry type quick connector with an eccentric structure comprises a quick connector valve body, the axis of an outlet of the quick connector valve body and the axis of an inlet of the quick connector valve body are not collinear, a three-legged support is arranged in the quick connector valve body and comprises a center frame, and a through hole is formed in the center of the center frame in the axial direction. The axis of the through hole and the axis of the outlet of the quick connector valve body are not collinear, and three supporting legs which are not evenly distributed are arranged on the periphery of the center frame at intervals in the circumferential direction. Due to the fact that the axis of the outlet of the quick connector valve body and the axis of the inlet are not collinear, namely, the quick connector valve body is of an outlet eccentric structure, the axis of the through hole of the three-legged support and the axis of the outlet of the quick connector valve body are collinear and coaxial, and meanwhile the three supporting legs of the three-legged support are distributed unevenly, enough moving space is reserved for a butterfly valve plate. Therefore, the valve plate of the butterfly valve can be prevented from interfering with the three-legged support in an open state.

Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to valves, especially a dry quick coupling with an eccentric structure. Background Technology

[0002] A dry-type quick coupling is a mechanical device that requires no liquid lubrication and allows for quick connection and disconnection of pipelines or equipment. Its core feature is its automatic sealing of both ends upon disconnection, preventing media leakage. It is suitable for scenarios requiring frequent connection switching (such as chemical and food processing). A dry-type quick coupling includes a valve body containing a tripod and a valve stem. One end of the valve stem passes through the center hole of the tripod, and the other end is connected to a valve plate. During operation, the valve stem moves along the axis of the center hole, opening and closing the valve plate. In existing technology, dry-type quick couplings are often used with flanged butterfly valves. However, when a flanged butterfly valve is opened, interference exists between the valve plate and the tripod, resulting in insufficient opening space for the valve plate and preventing the valve from opening effectively. Utility Model Content

[0003] The purpose of this invention is to provide a dry quick connector with an eccentric structure to solve the technical problem of interference between the butterfly valve plate and the tripod in the prior art when the valve plate is opened.

[0004] This utility model provides a dry quick coupling with an eccentric structure, including a quick coupling valve body. One end of the quick coupling valve body is provided with an inlet, and the other end is provided with an outlet. There is a gap between the axis of the outlet and the axis of the inlet of the quick coupling valve body. A tripod is provided in the quick coupling valve body. The tripod includes a central frame. The center of the central frame has a through hole along the axial direction. The axis of the through hole is collinear with the axis of the outlet of the quick coupling valve body. Three legs are provided circumferentially at intervals on the outer periphery of the central frame. The three legs form a first included angle, a second included angle, and a third included angle. The angle of the first included angle is greater than the angle of the second included angle and the angle of the third included angle. A valve stem is provided in the quick coupling valve body. One end of the valve stem passes through the through hole of the tripod and the other end of the valve stem is connected to a valve plate.

[0005] Furthermore, a sealing ring is provided between the valve plate and the quick-connect valve body 1.

[0006] Compared with existing technologies, the advantages of this invention are positive and significant. Because the outlet axis of the quick-connect valve body is not collinear with the inlet axis (i.e., it has an eccentric outlet structure), and the axis of the through hole of the tripod is collinear and coaxial with the outlet axis of the quick-connect valve body, and the three legs of the tripod are unevenly distributed, sufficient movement space is provided for the butterfly valve plate, preventing interference between the butterfly valve plate and the tripod when open. Furthermore, this eliminates the need to increase the overall height for this purpose, thus reducing the overall height of the dry quick-connect coupling to suit tanks with limited top space.

[0013] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0014] like Figures 1-6As shown, this utility model provides a dry quick connector with an eccentric structure, including a quick connector valve body 1. One end of the quick connector valve body 1 is provided with an inlet 2, and the other end of the quick connector valve body 1 is provided with an outlet 3. There is a gap between the axis of the outlet 3 of the quick connector valve body 1 and the axis of the inlet 2. A tripod 4 is provided in the quick connector valve body 1. The tripod 4 includes a central frame 41. The center of the central frame 41 is provided with a through hole 42 along the axial direction. The axis of the through hole 42 is collinear with the axis of the outlet 3 of the quick connector valve body 1. Three legs 43 are provided circumferentially around the outer periphery of the central frame 41. The three legs 43 form a first included angle, a second included angle, and a third included angle. The angle of the first included angle is greater than the angle of the second included angle and the angle of the third included angle. A valve stem 7 is provided in the quick connector valve body 1. One end of the valve stem 7 passes through the through hole 42 of the tripod 4, and the other end of the valve stem 7 is connected to a valve plate.

[0015] Furthermore, a sealing ring is provided between the valve plate and the quick-connect valve body 1.

[0016] Specifically, the valve stem 7, the valve plate, and other aspects not described in detail in this utility model all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here.

[0017] The working principle of this utility model:

[0018] After installation with butterfly valve 5, the axis of the butterfly valve body and the axis of the inlet 2 of quick-connect valve body 1 are collinear. Since the axis of the outlet 3 of quick-connect valve body 1 is not collinear with the axis of the inlet 2 (i.e., the outlet 3 has an eccentric structure), and the axis of the through hole 42 of the tripod 4 is collinear and coaxial with the axis of the outlet 3 of quick-connect valve body 1, and the three legs 43 of the tripod 4 are unevenly distributed, sufficient space is provided for the butterfly valve plate 6 to move, ensuring that the butterfly valve plate 6 avoids interference with the tripod 4 when open. Furthermore, this eliminates the need to increase the overall height for this purpose, thus reducing the overall height of the dry quick-connect fitting to suit tanks with limited top space.
