Abstract

The invention provides an integral multi-channel backflow prevention plug valve, which includes a valve body and a plurality of three-way plug valve units which are installed on the valve body. A first interface and a second interface are formed in both ends of the valve body correspondingly, plug valve interfaces perpendicular to the first interface and the second interface are formed in the valve bodies of the three-way plug valve units, the plug valve interfaces include a valve inner sleeve and a valve outer sleeve, the valve inner sleeve is installed in a valve body interface groove, the valve outer sleeve is installed outside the valve inner sleeve, a frustum hole is formed in a valve body between the valve body interface groove and the three-way plug valve units, and a frustum plug is arranged in the frustum hole. The plug valve is easy and convenient to use, a backflow prevention mechanism is arranged in a tee, and thus using is safer; and since both functions of a multi-channelcock and a backflow prevention valve are achieved, and especially when multi-channel infusion is needed in clinical ICU, multi-channel parallel infusion, single-channel infusion and multi-point infusion can be realized.

Example Embodiment

[0018] Such as figure 1 , 2 The integrated multi-channel anti-backflow plug valve shown in 3 includes a valve body 1 and a number of three-way plug valve units 2 mounted on the valve body 1. A first interface and a second interface are respectively provided at both ends of the valve body 1. The valve body of the three-way plug valve unit 2 is provided with a plug valve interface 3 perpendicular to the first interface and the second interface. The plug valve interface 3 includes a valve inner sleeve 31 and a valve outer sleeve 32. The valve inner sleeve 31 is installed on the valve In the body interface groove 33, the valve outer sleeve 32 is installed outside the valve inner sleeve 31, a frustum hole 34 is provided on the valve body 1 between the valve body interface groove 33 and the three-way plug valve unit 2, and a frustum hole 34 is provided in the frustum hole 34 Frustum plug 35.

[0019] A lock cap 4 is installed on the first interface, a plunger 41 matching the inner cavity of the first interface is arranged in the middle of the lock cap 4, and a screw is provided on the outer surface of the first interface to cooperate and lock with the internal thread of the lock cap 4.

[0020] A sheath 5 is installed on the second interface. The sheath 5 includes a socket 51 and a cap 52. The socket 51 is sleeved on the outer wall of the second interface and is locked with the outer wall through a buckle structure. Tightly, an extension tube 53 and a spiral tube 54 surrounding the extension tube are arranged on the socket 51, and the cap 52 is sleeved on the extension tube 53 and is screw-locked in the spiral tube 54.

[0021] The three-way cock valve unit 2 includes a cock body 21, three through holes are opened on the cock body 21, the lower part of the cock body 21 is sleeved on a lattice rib body 22 provided in the valve body 1, and the lattice rib body 22 is formed on a cylindrical body. A number of lattice ribs are arranged evenly spaced. The lower inner wall of the cock body 21 is also provided with lattice ribs. The lower outer wall of the cock body 21 is provided with grooves 23, and the corresponding valve body is provided with bumps to match the grooves 23.

[0022] The use of the rib body 22 allows the rotation angle to be adjusted, and the conduction positioning is more accurate. The matching of the bumps and grooves on the valve body limits the rotation process, especially the inner ribs of the cock body and the upper ribs. Limit function when ribs meet.

[0023] The integrated multi-channel anti-backflow plug valve is divided into two-way three-way, three-way three-way, four-way three-way and five-way three-way type.

[0024] The valve body 1 is also provided with a handle 6. The handle 6 is provided with a through hole in the middle. The setting of the handle makes it more convenient to take the valve body, and the handle is set to pass through, and it is convenient to hang and put, safe and sanitary.

[0025] The cock valve of the present invention is easy and convenient to use, and a reflux mechanism is provided in the three-way, making it safer to use; because it has the functions of a multi-channel cock and an anti-reflux valve, especially when the clinical ICU requires multi-channel infusion, it can achieve multiple Parallel infusion or single-channel infusion and multi-point infusion.

[0026] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its Equivalent replacements or changes in the conception shall all fall within the protection scope of the present invention.
