Description

Technical Field

[0001] The utility model relates to the technical field of magnetic sealing gate valves, in particular to a sealing structure of a magnetic sealing gate valve. Background Art

[0002] Plumbing is the process of delivering hot water to various parts of a building through a pipe system to meet heating, cooling or domestic water needs. Plumbing is usually used in conjunction with a magnetic sealing gate valve during the delivery process to control the delivery of hot or cold water in a suitable temperature environment. The magnetic sealing gate valve is a gate valve that uses magnetic principles to achieve sealing, which is used to prevent hot water from leaking when there is no need to deliver hot water.

[0003] The existing magnetic sealing gate valve also has the following defects when in use:

[0004] 1. The sealing structure of the magnetic sealing gate valve mostly adopts flat sealing. When hot water contacts the sealing structure, the impact force of the hot water is at its maximum, and the impact force of the water flow on the sealing structure is at its maximum. As a result, the sealing structure is easily worn under long-term erosion, thereby reducing the sealing performance of the sealing structure.

[0005] 2. If the sealing structure adopts concave and convex surfaces for sealing, most people choose concave surface sealing, which causes part of the water to enter the depression on the surface of the sealing structure during sealing, resulting in long-term existence of water flow inside the depression, which is easy to cause corrosion to the depression on the sealing structure, thereby reducing the service life of the sealing structure. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a sealing structure of a magnetic sealing gate valve, which can effectively solve the problems in the prior art.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model discloses a sealing structure of a magnetic sealing gate valve, comprising a sealing frame, receiving grooves are provided at both ends of the sealing frame, and buffer sealing mechanisms are provided at both ends of the sealing frame;

[0009] The buffer sealing mechanism is used to improve the sealing performance of the magnetic sealing gate valve and reduce the impact force of the liquid on the sealing frame during the sealing process. The buffer sealing mechanism can also disperse the liquid before reducing the impact force.

[0010] Furthermore, the buffer sealing mechanism includes an elastic mounting ring, which is fixedly connected to the inner wall of the storage groove, and the outer surface of the elastic mounting ring is fixedly connected to a sealing ring, and the side of the sealing ring away from the sealing frame is fixedly connected to a protrusion, and the protrusions are arranged in a ring shape on the side of the sealing ring away from the sealing frame.

[0011] Furthermore, a connecting plate is symmetrically fixedly connected to the outer surface of the sealing ring, and a connecting groove is formed at one end of the sealing frame close to the sealing ring, and the connecting groove is communicated with the receiving groove.

[0012] Furthermore, a plurality of buffer plates are arranged between the two connecting plates, the outer surface of the connecting plate is fixedly connected to the buffer plate close to the connecting plate, the buffer plates are arranged obliquely at one end of the sealing frame close to the sealing ring, and an installation groove is opened at the end of the sealing frame close to the sealing ring.

[0013] Furthermore, a control groove is provided at one end of the sealing frame close to the sealing ring, and the plurality of buffer plates are fixedly connected by a connecting rod, and the connecting rod can be inserted into the control groove.

[0014] Furthermore, the sealing frame is composed of a connecting column and two sealing blocks.

[0015] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0016] 1. The utility model uses the protrusions to disperse the impact force of the water flow before the hot water contacts the sealing frame, thereby reducing the degree of wear of the water flow on the sealing frame, which is beneficial to reducing the probability of reduced sealing performance due to wear of the sealing frame, thereby reducing the occurrence of water leakage in the magnetic sealing gate valve, and the protrusions and the sealing ring are used in conjunction with each other, which is beneficial to improving the sealing effect of the sealing frame.

[0017] 2. Before the water flows into contact with the sealing frame, the buffer plate and the connecting rod are used to further disperse the water flow, thereby greatly reducing the impact force of the water flow on the surface of the sealing frame. When the sealing frame moves upward, the buffer plate and the connecting rod can be moved into the installation groove and the control groove, thereby squeezing out the water flow inside the installation groove and the control groove, thereby preventing the water flow from remaining on the surface of the sealing frame for a long time, which is beneficial to reducing the corrosiveness of the water flow on the sealing frame, thereby extending the service life of the sealing frame.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] A sealing structure of a magnetic sealing gate valve in this embodiment, such as Figures 1 to 5 As shown, it includes a sealing frame 1, and receiving grooves 2 are opened at both ends of the sealing frame 1;

[0030] In view of the above-mentioned sealing frame 1, it can be specifically implemented as follows:

[0031] Buffer sealing mechanisms are provided at both ends of the sealing frame 1. The buffer sealing mechanisms are used to improve the sealing performance of the magnetic sealing gate valve and reduce the impact force of the liquid on the sealing frame 1 during the sealing process. The buffer sealing mechanisms can also disperse the liquid before reducing the impact force.

[0032] As a preferred implementation in this embodiment, Figure 2 、 Figure 3 and Figure 5 As shown, the buffer seal mechanism includes an elastic mounting ring 61, which is fixedly connected to the inner wall of the receiving groove 2. A sealing ring 62 is fixedly connected to the outer surface of the elastic mounting ring 61. The side of the sealing ring 62 facing away from the sealing frame 1 is fixedly connected to protrusions 63. The protrusions 63 are arranged in a ring shape on the side of the sealing ring 62 facing away from the sealing frame 1. A connecting plate 64 is symmetrically fixedly connected to the outer surface of the sealing ring 62. A connecting groove 5 is formed on the end of the sealing frame 1 near the sealing ring 62, which is connected to the receiving groove 2. The protrusions 63 disperse the impact force of the hot water before it contacts the sealing frame 1, thereby reducing the degree of wear on the sealing frame 1 caused by the water flow.

[0033] As a preferred implementation in this embodiment, as shown in the figure, a plurality of buffer plates 65 are arranged between the two connecting plates 64, and the outer surface of the connecting plate 64 is fixedly connected to the buffer plate 65 close to the connecting plate 64. The buffer plates 65 are arranged obliquely and arranged at one end of the sealing frame 1 close to the sealing ring 62. The end of the sealing frame 1 close to the sealing ring 62 is provided with a mounting groove 3, and the end of the sealing frame 1 close to the sealing ring 62 is provided with a control groove 4. The plurality of buffer plates 65 are fixedly connected by a connecting rod 66, and the connecting rod 66 can be inserted into the control groove 4. The sealing frame 1 is composed of a connecting column and two sealing blocks.

[0034] Working principle:

[0035] Initial limit:

[0036] Before using this utility, the user needs to install the connecting column on the sealing frame 1 on the internal driving structure of the magnetic sealing gate valve, and the movement process is from top to bottom. Figure 1 The figure shows the present invention when the magnetic sealing gate valve is in a sealed state;

[0037] Specific usage process:

[0038] First, as Figure 1As shown, when in use, the present invention disperses the impact force of the water flow through the projection 63 before the hot water contacts the sealing frame 1, thereby reducing the degree of wear of the water flow on the sealing frame 1, which is beneficial to reducing the probability of a decrease in sealing performance due to wear of the sealing frame 1, thereby reducing the occurrence of water leakage in the magnetic sealing gate valve. The projection 63 is provided at the front end of the sealing ring 62, which is beneficial to improving the sealing effect of the sealing frame 1 on the magnetic sealing gate valve after dispersing the impact force of the water flow, and further disperses the water flow through the buffer plate 65 and the connecting rod 66, thereby greatly reducing the impact force of the water flow on the surface of the sealing frame 1, thereby minimizing the impact force of the water flow on the sealing frame 1, and ensuring that the sealing frame 1 can be used for a long time and maintains good sealing performance.

[0039] When the magnetic sealing gate valve is in the open state, the sealing frame 1 moves upward as the driving structure in the magnetic sealing gate valve moves upward. When the sealing frame 1 moves upward, it drives the sealing ring 62 to move upward. When the sealing ring 62 moves upward, it is blocked by the inner wall of the magnetic sealing gate valve, so that the sealing ring 62 is compressed to Figure 5 As shown in the receiving groove 2, the sealing ring 62 drives the connecting plate 64 to enter the connecting groove 5 during the compression process. When entering the connecting groove 5, the connecting plate 64 drives the buffer plate 65 and the connecting rod 66 to enter the mounting groove 3 and the control groove 4, thereby squeezing out the water flow inside the mounting groove 3 and the control groove 4, thereby preventing the water flow from remaining on the surface of the sealing frame 1 for a long time, which is beneficial to reducing the corrosiveness of the water flow to the sealing frame 1, thereby extending the service life of the sealing frame 1.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
