[0002] A globe valve is an industrial valve used to control the flow of fluids. It offers low flow resistance and high sealing performance. When fully closed, it provides a reliable seal to prevent fluid leakage. The non-effluent sealed antibiotic globe valve is a valve specifically designed for use in the pharmaceutical, biochemical, and chemical industries, where high control of bacterial contamination rates is required during use.

[0003] Chinese patent publication number CN205806525U discloses an antibiotic shutoff valve disc, comprising a disc body with two cleaning holes radially leading into the mounting slot. This disc's advantage lies in utilizing one cleaning hole as a high-pressure water inlet and the other as a low-level drain hole. This allows for direct cleaning with a high-pressure V-port water gun, eliminating the need for disassembly and making cleaning more convenient and effective, while preventing contamination of the product.

[0004] However, the above technical solution has the following shortcomings: although the valve disc of the stop valve solves the problem of the valve disc being difficult to clean by setting two cleaning holes radially leading to the installation groove, there is a gap between the valve disc and the valve stem, and antibiotic medium will still continuously enter the gap, causing bacteria to be contaminated at the connection between the valve disc and the valve stem, affecting the use of the valve, and the valve disc and the valve stem are generally directly fixed by a traditional valve disc nut, and the stability of this connection method is poor. Utility Model Content

By improving the stability of the connection between the valve disc, the valve stem and the valve disc nut, the sealing performance of the valve disc during use is ensured, and the disadvantages of preventing the antibiotic medium from entering the interior of the connection to cause contamination and difficulty in handling are avoided.

[0006] The technical solution of the utility model is a valve disc of a liquid-free sealed antibiotic stop valve, comprising a valve disc body and a reinforcement mechanism; a mounting groove with an internal thread is arranged inside the valve disc body; the reinforcement mechanism comprises an annular groove arranged inside the mounting groove, a clamping ring arranged inside the annular groove, and a clamping assembly arranged below the clamping ring, the clamping assembly comprising two symmetrically distributed and slidingly arranged blocks inside the valve disc body, a guide rod arranged on the clamping block, and a spring at both ends respectively arranged on the valve disc body and the clamping block, and the spring is sleeved on the guide rod.

[0007] Preferably, a stepped hole is provided at the bottom of the mounting groove, and the axes of the mounting groove and the stepped hole coincide with each other.

[0008] Preferably, a concave hole is provided at the outlet of the installation groove, and the concave hole is in a truncated cone shape.

[0009] Preferably, a sliding groove is provided inside the valve flap body, and the guide rod is slidably provided inside the sliding groove.

[0010] Preferably, a cleaning hole is horizontally provided on the valve flap body, the cleaning hole is communicated with the step hole, and the valve flap body has a bevel.

[0011] Preferably, a sealing assembly is provided at the bottom of the valve flap body, and the sealing assembly includes a stud arranged on the valve flap body, a sealing cover passing through the stud and abutting against the valve flap body, a flat gasket squeezed against the sealing cover, an elastic gasket squeezed against the flat gasket, and a fixing nut threadedly connected to the stud.

[0012] Preferably, a limit ring is provided on the valve disc body, and the outer diameter of the sealing cover and the inner diameter of the limit ring are adapted to each other.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. The utility model greatly improves the stability of the connection between the valve stem and the valve disc body during installation by setting a reinforcement mechanism in conjunction with the step hole and the concave hole, avoiding the problem of inadequate sealing caused by the shaking of the valve stem.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the present embodiment proposes a valve disc of a liquid-free sealed antibiotic stop valve, comprising a valve disc body 1 and a reinforcement mechanism; a mounting groove 2 with an internal thread is provided inside the valve disc body 1, a step hole 3 is provided at the bottom of the mounting groove 2, the axis of the mounting groove 2 coincides with the axis of the step hole 3, a concave hole 10 is provided at the outlet of the mounting groove 2, and the concave hole 10 is in the shape of a truncated cone. The setting of the concave hole 10 can enable the valve disc nut to be screwed deeper into the internal thread when fixing the valve stem, thereby improving the tightness of the valve disc nut.

[0023] like Figure 1-Figure 3 As shown, the reinforcement mechanism includes an annular groove 4 arranged inside the mounting groove 2, a snap ring 5 arranged inside the annular groove 4, and a clamping assembly arranged below the snap ring 5. The clamping assembly includes two symmetrically distributed and sliding blocks 6 arranged inside the valve flap body 1, a guide rod 7 arranged on the block 6, and a spring 8 with two ends respectively arranged on the valve flap body 1 and the block 6. The spring 8 is sleeved on the guide rod 7. A slide groove 9 is provided inside the valve flap body 1. The guide rod 7 is slidably arranged inside the slide groove 9. The slide groove 9 is used to provide space for the guide rod 7 to slide.

[0024] In this embodiment, when installing the valve stem and the valve disc nut, first embed the valve stem head into the stepped hole 3, and then screw the valve disc nut into the installation groove 2. During the screwing process, the bottom of the valve disc nut will contact the clamping ring 5 and the clamping block 6 in turn. Since the clamping ring 5 is an open clamping ring, it will be squeezed into the annular groove 4, and the head shape of the clamping block 6 is an arc surface, the clamping block 6 will be squeezed by the valve disc nut, and then the clamping block 6 will compress the spring 8. The guide rod 7 guides the moving direction of the spring 8 and the clamping block 6. When the valve disc nut is screwed into the bottom, the clamping ring 5 will clamp the outer surface of the valve stem, and at the same time, the clamping block 6 is embedded in the valve stem under the action of the spring 8, thereby realizing the fixed installation of the valve stem, greatly improving the stability of the connection between the valve stem and the valve disc body 1 during installation, and avoiding the problem of inadequate sealing caused by the shaking of the valve stem.

[0027] In this embodiment, when the valve flap body 1 needs to be cleaned, a high-pressure water gun can be used to directly spray and clean it through the provided cleaning hole 11. This not only makes cleaning more convenient, but also has a good cleaning effect, preventing the product from being contaminated by bacteria. At the same time, the outlet of the cleaning hole 11 is located at the top of the inclined body 12, preventing moisture and media from remaining on the valve flap body 1.

[0030] A limit ring 13 is provided on the valve disc body 1 , and the outer diameter of the sealing cover 14 and the inner diameter of the limit ring 13 are adapted to each other.

[0031] In this embodiment, when installing the sealing assembly, the sealing cover 14 is first embedded in the interior of the limiting ring 13, and then the flat gasket 15 is fitted on the sealing cover 14 to increase the contact area with the sealing cover 14 to ensure that the sealing cover 14 is firmly fixed, and then the elastic gasket 17 is fitted on the flat gasket 15. The elastic gasket 17 can prevent it from accidentally sliding out after the fixing nut 18 is locked, thereby avoiding internal leakage, and the installation and disassembly operations are simple. Finally, the fixing nut 18 is screwed together with the stud 16, and the elastic gasket 17 is squeezed to complete the fixed installation of the sealing assembly.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
