Description

Technical Field

[0001] This application relates to the field of hydraulic sealing, and in particular to a static sealing ring for a hydraulic support hose joint. Background Technology

[0002] Hydraulic support hoses are used on hydraulic supports, and their main function is to safely and reliably transmit high-pressure emulsion. In order to ensure that the high-pressure emulsion does not leak, existing hydraulic support hose joints are usually equipped with sealing structures.

[0003] Existing sealing mechanisms (such as) Figure 4 As shown, the device includes an O-ring 8 with a circular interface and a retaining ring 9 with a rectangular interface. By installing the O-ring 8 and the retaining ring 9 in the groove 7 on the side wall of the male connector 5, the sealing performance at the connection between the male connector 5 and the female connector 6 is improved by squeezing the O-ring 8 and the retaining ring 9 when the male connector 5 is mated with the female connector 6. However, in the existing sealing mechanism, the O-ring 8 is prone to rolling displacement during use, has poor stability, and is easily squeezed out of the groove 7 on the side wall of the male connector 5, thereby affecting the normal fit between the male connector 5 and the female connector 6 and increasing the difficulty of mating the male connector 5 and the female connector 6. Utility Model Content

[0004] To reduce the probability of the sealing mechanism affecting the joint fit, this application provides a static sealing ring for a hydraulic support hose joint.

[0005] The static sealing ring structure of the hydraulic support hose joint provided in this application adopts the following technical solution:

[0006] A static sealing ring for a hydraulic support hose connector includes a base ring and a sealing ring, which are integrally formed. The sealing ring is circular on the side away from the base ring, and the base ring has a chamfer on the side away from the sealing ring.

[0007] By adopting the above technical solution, the base ring and sealing ring are integrally molded and can be installed more stably in the groove of the joint, which facilitates the installation of the sealing mechanism and improves the installation efficiency. When the female joint is guided and pressed at the base ring, since the base ring and sealing ring are integral structures, they are relatively stable in the groove. Therefore, the sealing ring is not easily squeezed out of the groove, thereby reducing the probability that the sealing mechanism will affect the joint fit.

[0008] Optionally, a deformation groove is provided at the connection between the base ring and the sealing ring.

[0009] By adopting the above technical solution, the deformation groove can provide deformation space for the base ring, thereby reducing the probability that the deformation force will be transmitted to the sealing ring when the base ring is squeezed and deformed, and thus reducing the probability that the sealing ring will deform and protrude out of the groove due to the pressure of the base ring.

[0010] Optionally, the radial dimension of the base ring is smaller than the radial dimension of the sealing ring.

[0011] By adopting the above technical solution, the radial dimension of the sealing ring is larger than that of the base ring, so that the sealing ring has an initial interference fit in the groove. When pressure comes, it provides space for the sealing ring to deform, thereby effectively preventing the end edge of the base ring from being squeezed into the gap between the female and male joints due to deformation, thus improving the stability and service life of the entire sealing structure.

[0012] Optionally, the sealing ring is a hydrolysis-resistant polyurethane elastic sealing ring.

[0013] By adopting the above technical solutions, polyurethane has the characteristics of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, and elasticity, which can improve the durability of the sealing ring and thus extend its service life.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] The integral molding of the base ring and sealing ring allows for more stable installation within the joint groove, facilitating the installation of the sealing mechanism and improving installation efficiency.

[0016] The radial dimension of the sealing ring is larger than that of the base ring, so that the sealing ring has an initial interference fit in the groove. When pressure comes, it provides space for the sealing ring to deform, thereby effectively preventing the end edge of the base ring from being squeezed into the gap between the female and male joints due to deformation, thus improving the stability and life of the entire sealing structure.

[0017] Polyurethane is characterized by its oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, and elasticity, which can improve the durability of the sealing ring and thus extend its service life. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] This application discloses a static sealing ring for a hydraulic support hose connector, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a base ring 1 and a sealing ring 2. The base ring 1 and sealing ring 2 are integrally machined on a high-precision CNC lathe, featuring structural stability and ease of production. Both the base ring 1 and sealing ring 2 are uniformly circular rings, with the sealing ring 2 having a circular shape on the side furthest from the base ring 1. A chamfer 3 is formed on the side of the base ring 1 furthest from the sealing ring 2. The integral molding of the base ring 1 and sealing ring 2 allows for more stable installation within the groove 7 of the joint, facilitating the installation of the sealing mechanism and improving installation efficiency. The circular ring on the sealing ring 2 deforms appropriately under liquid pressure, sealing the female joint 6 and male joint 5. When the sealing ring is under unstable force... When the size increases, the deformation of the sealing ring 2 increases, and the reverse extrusion force generated by the sealing ring 2 and the contact area with the inner wall of the male connector 5 will also increase, so as to achieve effective sealing performance. The shape and structure of the sealing ring 2, combined with the chamfers 3 on both sides of the base ring 1, makes the entire sealing ring have the characteristic of gradually increasing radial size from the inside to the outside. This allows the sealing ring as a whole to gradually improve its sealing performance and reverse extrusion resistance as the deformation increases. When the female connector 6 is guided and pressed at the base ring 1, since the base ring 1 and the sealing ring 2 are fixed, the sealing ring 2 is not easily squeezed out of the groove 7, thereby reducing the probability that the sealing mechanism will affect the joint fit.

[0026] Reference Figure 1 , Figure 2 and Figure 3A deformation groove 4 is provided at the connection between the base ring 1 and the sealing ring 2. The deformation groove 4 can provide deformation space for the base ring 1, thereby reducing the probability that the deformation force is transmitted to the sealing ring 2 when the base ring 1 is squeezed and deformed, thereby reducing the probability that the sealing ring 2 will deform and extend out of the groove 7 due to the pressure of the base ring 1.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The radial dimension of the base ring 1 is smaller than that of the sealing ring 2, and the radial dimension of the sealing ring 2 is larger than that of the base ring 1. This allows the sealing ring 2 to have an initial interference fit in the groove 7, providing space for deformation of the sealing ring when pressure is applied. This effectively prevents the end edge of the base ring 1 from being squeezed into the gap between the female connector 6 and the male connector 5 due to deformation, thereby improving the stability and lifespan of the entire sealing structure.

[0028] Reference Figure 1 , Figure 2 and Figure 3 Both the sealing ring 2 and the base ring 1 are hydrolysis-resistant polyurethane elastic sealing rings. The sealing rings are made of hydrolysis-resistant polyurethane with a Shore hardness of 93±3A. Polyurethane has the characteristics of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity, which can improve the durability of the sealing ring and thus improve its service life.

[0029] The implementation principle of this application embodiment is as follows: the base ring 1 and the sealing ring 2 are installed in the groove 7 of the male connector 5, and then the male connector 5 and the female connector 6 are connected. The female connector 6 first abuts against the chamfer 3 of the base ring 1, and is gradually fitted onto the male connector 5 by the guide of the chamfer 3. The base ring 1 is deformed under the installation of the female connector 6. Then the female connector 6 passes through the sealing ring 2. After the female connector 6 squeezes the sealing ring 2, the sealing ring 2 is deformed. Then the connection between the female connector 6 and the male connector 5 is completed.
