Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a multi-turn valve structure for insulating jacket media. Background Technology
[0002] Insulated gate valves and jacketed gate valves are mainly used in various systems such as petroleum, chemical, metallurgy, and pharmaceutical industries to transport high-viscosity media that agglomerate at room temperature. The jacket of this series of valves is welded between the two flanges of the valve, and the side and bottom of the valve have connection ports for the jacket (inlet / outlet of the insulation medium or drain). Due to the addition of the jacket, the connecting flange size of this type of valve is one to two sizes larger than that of a standard connecting flange of the same specification, but the structural length is the same as that of a valve of the same specification.
[0003] In existing technologies, while insulated gate valves or jacketed gate valves can ensure smooth flow of high-viscosity media through the insulating medium within the jacket, the direct scouring of the insulating medium against the valve body inlet wall can easily lead to a temperature difference in the medium's conduction within the inlet and outlet valve chambers, affecting heat transfer efficiency and potentially damaging the valve body. To address these shortcomings, this invention provides a multi-turn valve structure for the insulating jacketed medium, thus solving the aforementioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a multi-turn valve structure for the insulation jacket medium. The insulation medium flowing within the insulation jacket ensures smooth flow of high-viscosity media within the valve. The first and second anti-erosion plates improve heat transfer efficiency, protect the valve body, and reduce dead zones by altering the flow direction and velocity of the insulation medium. This allows for sufficient heat exchange of the medium within the valve cavity, resulting in less valve wear, a longer service life, and meeting operational requirements.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a valve structure for multi-turning medium in insulation jackets, comprising a valve body, a valve cover, a valve stem, a valve disc, and an insulation jacket;
[0006] The valve cover is disposed on the valve body body;
[0007] The valve stem is threaded onto the valve cover;
[0008] The valve disc is disposed on the valve stem and located inside the valve body;
[0009] The insulation jacket is disposed outside the valve body and is used to load the insulation medium. The insulation jacket is provided with an insulation medium inlet and an insulation medium outlet on its exterior. The insulation jacket is provided with a first anti-erosion plate and a second anti-erosion plate in its inner cavity.
[0010] Preferably, the first anti-erosion plate and the second anti-erosion plate are respectively installed at the positions of the insulation medium inlet and the insulation medium outlet.
[0011] Preferably, the first and second anti-erosion plates are respectively fixedly connected to the insulation jacket with reinforcing ribs.
[0012] Preferably, the valve body is provided with an insulation flange, which is connected to an insulation jacket.
[0013] Preferably, the valve cover is provided with a packing body, and a packing sleeve is movably engaged on the valve cover, with the packing body located between the valve cover and the valve stem.
[0014] Preferably, the valve stem is provided with a drive handwheel.
[0015] Preferably, a retaining bolt is threaded between the valve cover and the valve body.
[0016] This utility model discloses a multi-turn valve structure for insulating jacket media, which has the following beneficial effects:
[0017] This multi-turn valve structure with a heat-insulating jacket ensures smooth flow of high-viscosity media within the valve by utilizing the heat-insulating medium flowing within the jacket. The first and second anti-erosion plates improve heat transfer efficiency, protect the valve body, and reduce dead zones by altering the flow direction and velocity of the heat-insulating medium. This allows for sufficient heat exchange of the medium within the valve cavity, resulting in less valve wear, a longer service life, and meeting operational requirements. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] This application provides a multi-turn valve structure for the insulation jacket medium, which solves the problem in the prior art where, although the insulation medium in the insulation jacket ensures smooth flow of high-viscosity media, the insulation medium directly washes against the valve body inlet wall, which can easily lead to a temperature difference in the medium conduction inside the inlet and outlet valve chambers, affecting heat transfer efficiency and potentially damaging the valve body.
[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0025] Example 1:
[0026] This utility model discloses a multi-turn valve structure for insulating jacket media, according to the attached... Figure 1-2 As shown, it includes valve body 1, valve cover 2, valve stem 3, valve disc 4, and insulation jacket 5;
[0027] The valve body 1 serves as the core supporting structure of the valve, forming an internal channel for media flow. In systems such as petroleum, chemical, metallurgical, and pharmaceutical industries, it is used to contain and guide the flow of high-viscosity media. During use, the valve body 1 must be correctly connected to the piping system to ensure unobstructed media flow.
[0028] The valve cover 2 is mounted on the valve body 1, serving to seal and support the valve stem 3. A packing body 21 is mounted on the valve cover 2, and is secured by a packing sleeve 22. The packing body 21 is located between the valve cover 2 and the valve stem 3 to prevent media leakage. During installation, it is essential to ensure that the packing body 21 is properly installed and the packing sleeve 22 is securely tightened to guarantee a good seal.
[0029] The valve stem 3 is threaded onto the valve cover 2, and a drive handwheel 31 is provided on the valve stem 3. By rotating the drive handwheel 31, the valve stem 3 can be moved up and down, thereby controlling the opening and closing of the valve disc 4. The valve stem 3 is designed to ensure sufficient strength and wear resistance to withstand frequent operation and high-pressure environments.
[0030] The valve disc 4 is mounted on the valve stem 3 and located inside the valve body 1. It moves up and down with the movement of the valve stem 3 to control the flow and cut off of the medium. The material of the valve disc 4 must be selected according to the characteristics of the medium to ensure good sealing and corrosion resistance.
[0031] The insulation jacket 5 is located outside the valve body 1 and is used to hold the insulation medium. The insulation jacket 5 has an insulation medium inlet 51 and an insulation medium outlet 52 on its exterior, and a first anti-erosion plate 511 and a second anti-erosion plate 521 inside. In use, the insulation medium flows in through the inlet 51, passes through the anti-erosion plates to change its flow direction and velocity, increases the flow path, improves heat transfer efficiency, and finally flows out through the outlet 52. The design of the first anti-erosion plate 511 and the second anti-erosion plate 521 effectively prevents the insulation medium from directly eroding the valve body surface, protecting the valve body, reducing dead zones, and ensuring sufficient heat exchange of the medium in the valve cavity.
[0032] Example 2:
[0033] This utility model discloses a multi-turn valve structure for insulating jacket media, according to the attached... Figure 1-2 As shown, it includes valve body 1, valve cover 2, valve stem 3, valve disc 4, and insulation jacket 5;
[0034] Valve cover 2 is mounted on valve body 1;
[0035] The valve stem 3 is threaded onto the valve cover 2;
[0036] The valve disc 4 is mounted on the valve stem 3 and located inside the valve body 1;
[0037] The insulation jacket 5 is located outside the valve body 1 and is used to load the insulation medium. The insulation jacket 5 has an insulation medium inlet 51 and an insulation medium outlet 52 on its outside. The insulation jacket 5 has a first anti-erosion plate 511 and a second anti-erosion plate 521 in its inner cavity.
[0038] The first anti-erosion plate 511 and the second anti-erosion plate 521 are respectively installed at the positions of the insulation medium inlet 51 and the insulation medium outlet 52.
[0039] The first scour protection plate 511 and the second scour protection plate 521 are respectively fixedly connected to the insulation jacket 5 with reinforcing ribs 6. The reinforcing ribs 6 enhance the stability of the scour protection plates and prevent them from loosening or being damaged due to the impact of the insulation medium.
[0040] The valve body 1 is equipped with an insulation flange 11, which is connected to the insulation jacket 5. The insulation flange 11 provides an interface for the flow of the insulation medium and ensures the sealing of the connection.
[0041] The valve cover 2 is provided with a packing body 21, and a packing sleeve 22 is movably snapped onto the valve cover 2. The packing body 21 is located between the valve cover 2 and the valve stem 3.
[0042] A retaining bolt 23 is threaded between the valve cover 2 and the valve body 1. The retaining bolt 23 is used to fasten the valve cover 2, ensuring the overall stability and sealing of the valve.
