Description

Technical Field

[0001] This utility model relates to the field of water for injection, and in particular to a hot water press. Background Technology

[0002] In the preparation of water for injection, the raw water undergoes a series of rigorous treatment steps, including high-temperature heating and evaporation to remove impurities and obtain pure steam. However, during the high-temperature heating process, the sealing ring, as a key component connecting the tank body and lid, requires particularly stable performance. If the sealing ring softens under prolonged high-temperature exposure, it may separate from the tank body, affecting the seal and ultimately impacting the overall heating effect and the purity of the water.

[0003] Therefore, there is an urgent need to develop a hot water press to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hot water press that can prevent the sealing ring from softening and separating from the tank due to long-term high temperature, thereby avoiding affecting the sealing performance.

[0005] To solve the above-mentioned technical problems, this utility model provides a sealing structure for a hot water press, including a sealing ring and a dovetail groove provided on the part to be engaged;

[0006] The dovetail groove includes a first side, a second side, and a third side connected in sequence; there is a predetermined distance between one end of the first side and one end of the third side, and one end of both the first side and the third side are connected to the edge of the component to be fastened; the other end of the first side extends away from the third side until it connects with one end of the second side; the other end of the third side extends away from the first side until it connects with the other end of the second side, to form a dovetail structure; one end of the sealing ring is located inside the dovetail structure.

[0007] Furthermore, the cross-section of the sealing ring is circular or rectangular.

[0008] Furthermore, the connection between the first edge and the edge of the component to be fastened is chamfered or rounded.

[0009] Furthermore, the connection between the third side and the edge of the component to be clipped is chamfered or rounded.

[0010] Furthermore, the vertical distance between the second side and the edge of the component to be fastened is greater than the radius of the sealing ring.

[0011] Furthermore, the distance between one end of the first side and one end of the third side is less than the length of the second side.

[0012] Furthermore, the distance between one end of the first side and one end of the third side is less than the diameter of the sealing ring.

[0013] Furthermore, the connection points between the first and second sides, and between the third and second sides, are all chamfered or rounded.

[0014] Furthermore, the sealing ring is made of elastic fluororubber.

[0015] In addition, this utility model also proposes a hot water press, including the sealing structure for hot water press as described above, and further including a tank body, a tank cover, a first flange and a second flange; the first flange is connected to the open end of the tank body; the second flange is connected to the tank cover; the first flange is provided with a dovetail groove; the first flange is connected to the second flange; the sealing ring is located between the first flange and the second flange, and the end away from the second flange is engaged in the dovetail groove.

[0016] Through the above technical solution, this utility model has the following beneficial effects:

[0017] The device employs a sealing ring and a dovetail groove on the component to be fitted. The dovetail groove comprises a first side, a second side, and a third side connected in sequence. A predetermined distance exists between one end of the first side and one end of the third side, and both ends of the first and third sides are connected to the edge of the component to be fitted. The other end of the first side extends away from the third side until it connects to one end of the second side. The other end of the third side extends away from the first side until it connects to the other end of the second side, forming a dovetail structure. One end of the sealing ring is located inside the dovetail structure. The sealing ring of this device is fitted within the dovetail groove. When the sealing ring expands or softens due to heat, the narrower end of the dovetail groove (i.e., the connection point between the first side and the edge of the component to be fitted, and the connection point between the third side and the edge of the component to be fitted) can tightly hold the sealing ring, thereby preventing the sealing ring from softening at long-term high temperatures and separating from the tank. This avoids affecting the sealing performance and contributes to the subsequent heating effect and water purity. Attached Figure Description

[0021] The following is a more detailed description of a hot water press according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0022] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] like Figures 1-2 As shown in the figure, this utility model embodiment proposes a convenient and practical sealing structure for a hot water press, including a sealing ring 1 and a dovetail groove provided on the locking part 3.

[0024] Specifically, the dovetail groove includes a first side 21, a second side 22, and a third side 23 connected in sequence; there is a predetermined distance between one end of the first side 21 and one end of the third side 23, and one end of both the first side 21 and the third side 23 is connected to the edge 31 of the component to be fastened 3; the other end of the first side 21 extends away from the third side 23 until it connects with one end of the second side 22; the other end of the third side 23 extends away from the first side 21 until it connects with the other end of the second side 22, thus forming a dovetail structure; one end of the sealing ring 1 is located inside the dovetail structure. The dovetail groove helps to more tightly fix the sealing ring 1 and reduce the possibility of leakage.

[0025] In this embodiment, the cross-section of the sealing ring 1 is circular or rectangular. The cross-section of the sealing ring 1 can be circular or rectangular, providing design flexibility to adapt to different application requirements. Those skilled in the art will understand that, to achieve the same effect, the cross-section of the sealing ring 1 can also be other shapes besides those in this embodiment.

[0026] In a preferred embodiment, the connection between the first edge 21 and the edge 31 of the component to be fastened 3 is chamfered or rounded.

[0027] In a preferred embodiment, the connection between the third side 23 and the edge 31 of the component to be clipped 3 is chamfered or rounded.

[0028] In this embodiment, the connection points between the first side 21 and the third side 23 and the edge 31 of the component to be secured 3 are chamfered or rounded. If a corner is used, the fluororubber sealing ring 1 may be punctured by the corner point during its entry into the dovetail groove due to the sharpness of the corner. Therefore, this embodiment uses chamfers or rounded corners to help reduce stress concentration and improve the durability of the structure. In addition, the chamfers or rounded corners have smooth surfaces, which facilitates the sealing ring 1 to enter the dovetail groove along the smooth surface.

[0029] In this embodiment, the vertical distance between the second side 22 and the edge 31 of the component to be fitted 3 is greater than the radius of the sealing ring 1. Since the sealing ring 1 needs to fit more than half of its size into the dovetail groove, the vertical distance between the second side 22 and the edge 31 of the component to be fitted 3 needs to be greater than the radius of the sealing ring 1 to better accommodate it and avoid the phenomenon of insufficient space preventing proper fitting.

[0030] In this embodiment, the distance between one end of the first side 21 and one end of the third side 23 is less than the length of the second side 22.

[0031] In this embodiment, the distance between one end of the first side 21 and one end of the third side 23 is smaller than the diameter of the sealing ring 1. This helps ensure the correct positioning and engagement of the sealing ring 1 within the dovetail groove.

[0032] In this embodiment, the connection between the first side 21 and the second side 22, and the connection between the third side 23 and the second side 22, are both chamfered or rounded.

[0033] In this embodiment, the sealing ring 1 is made of elastic fluororubber. Those skilled in the art will understand that, to achieve the same effect, the sealing ring 1 can be made of other materials besides those in this embodiment.

[0034] In addition, continue to refer to Figure 2 As shown, this embodiment also proposes a hot water press, including the sealing structure for hot water presses as described above, and further including a tank body, a tank cover, a first flange, and a second flange 4. Specifically, the first flange is connected to the open end of the tank body; the second flange 4 is connected to the tank cover; the first flange is provided with a dovetail groove; the first flange is connected to the second flange 4; the sealing ring 1 is located between the first flange and the second flange 4, and the end away from the second flange 4 is engaged in the dovetail groove.

[0035] In this embodiment, a dovetail groove is formed on the first flange, and the fluororubber sealing ring 1 is fitted into the dovetail groove. When the second flange 4 is connected to the first flange, the sealing ring 1 is located between the two and is subjected to compressive force. When the tank is in a high-temperature environment for a long time, the sealing ring 1 is subjected to pressure from the opening end of the dovetail groove (i.e., the narrower end) during the softening or thermal expansion process, and therefore cannot detach from the dovetail groove.

[0036] In summary, the hot water press proposed in this utility model has the following advantages:

[0037] The device employs a sealing ring and a dovetail groove on the component to be fitted. The dovetail groove comprises a first side, a second side, and a third side connected in sequence. A predetermined distance exists between one end of the first side and one end of the third side, and both ends of the first and third sides are connected to the edge of the component to be fitted. The other end of the first side extends away from the third side until it connects to one end of the second side. The other end of the third side extends away from the first side until it connects to the other end of the second side, forming a dovetail structure. One end of the sealing ring is located inside the dovetail structure. The sealing ring of this device is fitted within the dovetail groove. When the sealing ring expands or softens due to heat, the narrower end of the dovetail groove (i.e., the connection point between the first side and the edge of the component to be fitted, and the connection point between the third side and the edge of the component to be fitted) can tightly hold the sealing ring, thereby preventing the sealing ring from softening at long-term high temperatures and separating from the tank. This avoids affecting the sealing performance and contributes to the subsequent heating effect and water purity.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
