Description

Technical Field

[0001] The utility model relates to the technical field of flange joints, in particular to a detachable double-flange force transmission joint. Background Art

[0002] The double flange force transfer joint is a loose sleeve connection device used for pumps, valves and other accessories. It achieves compensation function by adjusting the movable nut and the length between the joint and the force transfer joint sleeve. During operation, the axial thrust can be transmitted to the entire pipeline, which not only improves work efficiency, but also protects equipment such as pumps and valves.

[0003] A Chinese patent discloses a detachable double-flange force transmission joint (authorization announcement number CN220688315U). The patented technology is provided with an auxiliary support mechanism, which adjusts the length of the sleeve inside the support rod in the auxiliary support mechanism, and then rotates the fixing screw to fix the sleeve. The sleeve can support the gland and the sealing gasket, provide a carrier for the installation of the gland and the sealing gasket, effectively avoid the gland and the sealing gasket from being tilted during installation, and avoid the formation of a gap between the sealing gasket and the gland.

[0004] However, most of the existing double-flange force transmission joints adopt a sealing method of wrapping a sealing tape around the outside of the gland, resulting in poor sealing between the gland and the telescopic short tube, which is prone to leakage, as shown in the above-mentioned comparative document. In actual application, when adjusting the distance between the telescopic short tube and the gland, the sealing effect of only using the sealing tape is poor, and the gap between the telescopic short tube and the gland cannot be sealed, resulting in leakage. Therefore, those skilled in the art provide a detachable double-flange force transmission joint to solve the problems raised in the above-mentioned background technology. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution of a detachable double-flange force transmission joint: it includes: a body 1, a pressure cover 2 arranged above the body 1 and a telescopic short tube 3 installed above the pressure cover 2, the body 1, the pressure cover 2 and the telescopic short tube 3 are jointly installed with a connecting screw 6, and the outside of the body 1 and the telescopic short tube 3 are both installed with a protective mechanism 4, the protective mechanism 4 consists of a first protective layer 41, a filling layer 42, a sound insulation layer 43 and a second protective layer 44, the upper surface of the pressure cover 2 is provided with a sealing mechanism 5 below the telescopic short tube 3, the sealing mechanism 5 includes a sealing sleeve 51 arranged below the telescopic short tube 3, the lower surface of the sealing sleeve 51 is symmetrically provided with an adjusting screw 53, and the upper surface of the sealing sleeve 51 is provided with a first sealing gasket 54, and the inner side of the sealing sleeve 51 is also provided with a second sealing gasket 55. This arrangement utilizes the sealing sleeve 51 in the sealing mechanism 5 to contact the lower surface of the telescopic short tube 3, and the first sealing gasket 54 and the second sealing gasket 55 can improve the sealing of the connection.

[0023] like Figure 2 and Figure 3 As shown, the first sealing gasket 54 is made of rubber, and the upper surface of the first sealing gasket 54 contacts the lower surface of the telescopic short tube 3. This arrangement using the first sealing gasket 54 can ensure efficient sealing between the sealing sleeve 51 and the telescopic short tube 3.

[0024] like Figure 2 and Figure 3 As shown, the second sealing gasket 55 is also made of rubber, and the inner side of the second sealing gasket 55 contacts the outer surface of the gland 2 . This arrangement utilizes the second sealing gasket 55 to achieve sealing between the telescopic short tube 3 and the gland 2 .

[0025] like Figure 2 and Figure 3 As shown, four adjusting screws 53 are symmetrically arranged on the lower surface of the sealing sleeve 51, and the lower ends of the adjusting screws 53 pass through the lower surface of the gland 2. The outside of the adjusting screws 53 is provided with locking nuts 531 on the upper and lower surfaces of the gland 2. The sealing sleeve 51 is a hollow disc with a small upper part and a large lower part. This setting uses the locking nuts 531 to adjust the height of the adjusting screws 53, that is, the height of the sealing sleeve 51 is adjusted according to the height of the telescopic short tube 3, so that the upper surface of the sealing sleeve 51 contacts the telescopic short tube 3 to achieve the purpose of efficient sealing.

[0026] like Figure 4 As shown, the first protective layer 41 and the second protective layer 44 have the same thickness, and the sound insulation layer 43 is made of rock wool. This arrangement utilizes the first protective layer 41 and the second protective layer 44 to achieve the purpose of protecting the main body 1 and the telescopic short tube 3, and the sound insulation layer 43 can reduce noise.

[0027] When the detachable double flange force transmission joint of the present invention is in use, the lower end of the adjusting screw 53 in the sealing mechanism 5 is first passed through the lower surface of the pressure cover 2, thereby realizing the purpose of installing the sealing sleeve 51. After installation, the body 1, the pressure cover 2 and the telescopic short tube 3 are connected in sequence and locked by the connecting screw 6 and the external nut. Similarly, the body 1, the pressure cover 2 and the telescopic short tube 3 can be disassembled by rotating and unscrewing the external nut. After the telescopic short tube 3 is installed, the upper surface of the sealing sleeve 51 will contact the lower surface of the telescopic short tube 3. After the telescopic short tube 3 is adjusted, the height of the adjusting screw 53 is adjusted by rotating the locking nut 531 outside the adjusting screw 53, so that the upper end of the sealing sleeve 51 is always in contact with the lower surface of the telescopic short tube 3, thereby ensuring the sealing between the telescopic short tube 3 and the pressure cover 2. At the same time, a second sealing gasket 55 is also provided on the inner side of the sealing sleeve 51, thereby improving the sealing of the connection.

The protective mechanism 4 consists of a first protective layer 41, a filling layer 42, a sound insulation layer 43 and a second protective layer 44. In this way, the first protective layer 41 and the second protective layer 44 can be used to effectively protect the outside of the main body 1 and the telescopic short tube 3 to prevent them from being damaged by external factors. In addition, the sound insulation layer 43 and the filling layer 42 can provide the main body 1 and the telescopic short tube 3 with a certain sound insulation effect. The structure is simple and the practicality is good.

[0029] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
