Description

Sealing joint

Technical Field

The present invention relates to a joint, and more particularly to a vacuum joint radial seal joint for semiconductor optoelectronic industry.

Background

As shown in fig. 1, a joint 1 mainly includes a first Coupling pipe 11, a second Coupling pipe 12, a gasket 13, a male nut 14 and a female nut 15. The first and second connecting

pipes

11 and 12 respectively have

pipe ends

111 and 121 and

sealing ends

112 and 122 with

flanges

113 and 123 at their two ends, and the gasket 13 includes a movable gasket 131, and the male and

female nuts

14 and 15 respectively have through

holes

141 and 151 for the first and second connecting

pipes

11 and 12 to pass through.

In assembly, referring to fig. 1 and fig. 2, the first connecting pipe 11 and the second connecting pipe 12 are respectively inserted into the through

holes

141 and 151 of the male nut 14 and the female nut 15, the flange 113 of the first connecting pipe 11 and the flange 123 of the second connecting pipe 12 are oppositely disposed, the gasket 13 is embedded in the flange 113 of the first connecting pipe 11, the male nut 14 is manually screwed into the female nut 15, the movable gasket 131 is abutted between the flange 113 of the first connecting pipe 11 and the flange 123 of the second connecting pipe 12, when the male nut 14 cannot be manually screwed into the female nut 15, a reference line L is drawn by using a corresponding end surface of the male nut 14 and the female nut 15 as a reference surface, the male nut 14 is fixed by a wrench, and the female nut 15 is rotated by about 1/8 to 1/6 circles by another wrench, so that the reference line L of the male nut 14 and the female nut 15 is spaced by 45 degrees to 60 degrees, the flange 113 of the first coupling pipe 11 and the flange 123 of the second coupling pipe 12 are pressed against the movable gasket 131 to achieve the pipeline sealing state of the joint 1 (as shown in fig. 3).

However, the force applied to the joint 1 by different operators or even the same operator each time using the wrench is not uniform, and therefore, the conventional assembly method can only specify the angular range of the wrench for pulling the nut 15, and cannot lock each joint 1 in a fixed position, so that the force of the flange 113 of the first coupling pipe 11 and the force of the flange 123 of the second coupling pipe 12 pressing against the movable gasket 131 are not uniform. In practice, it is found that an operator with a large force may wear or even deform the movable gasket 131 due to a large rotation angle of the nut 15 pulled by the wrench, so that the joint 1 cannot be reassembled for use after being disassembled, which obviously has a drawback to be improved.

To overcome the above-mentioned disadvantages, U.S. Pat. No. 05058935A discloses a "fluid accessory with torque suppression device", in which an annular driving member is disposed between a female nut and a first coupling member, the annular driving member is formed with a tapered angle, and a male nut is provided with a groove having a tapered angle, so that when the female nut and the male nut are screwed together, the groove of the male nut is engaged with the annular driving member to restrict the transmission of the rotational force of the female nut.

Further, U.S. Pat. No. US06308994B1 discloses a "fluid fitting with torque restraint device", in which a groove is formed at an end of a first coupling member or a second coupling member, and a torque restraint assembly including a ring and a thrust member is installed in the groove, so that when a female nut is screwed with a male nut, transmission of rotational force of the female nut is restrained by the torque restraint assembly.

SUMMERY OF THE UTILITY MODEL

In view of the fact that the conventional joint assembly method cannot lock each joint in a fixed position, the force of the two joint pipes pressing against the movable gasket is inconsistent, and there is obviously a drawback to be improved.

To achieve the above and other objects, a more complete disclosure of the present invention is provided in the following detailed description, which refers to the accompanying drawings and numbers:

first, referring to fig. 4 to 6, the sealing joint 2 of the present invention includes a first coupling pipe 21, a second coupling pipe 22, a gasket 23, a male nut 24 and a female nut 25. Wherein, one end of the first coupling pipe fitting 21 forms a pipe fitting end 211, the other end forms a sealing end 212 with a neck 213, and a first flange 214 is arranged on the sealing end surface; the second coupling tube 22 has a fitting end 221 formed at one end and a sealing end 222 having a neck 223 formed at the other end, and a second flange 224 formed at the sealing end; the washer 23 includes a movable gasket 231, and the movable gasket 231 abuts between the first flange 214 of the first coupling pipe 21 and the second flange 224 of the second coupling pipe 22; the male nut 24 forms a nut section 241 and a stud section 242, and the stud section 242 is provided with a through hole 243 with an opening end 244, the through hole 243 is used for the first connecting pipe 21 to pass through, and the neck 213 of the first connecting pipe 21 is attached to the opening end 244; the female nut 25 forms a receiving groove 251, and the receiving groove 251 has a through hole 252, the through hole 252 is used for the second coupling tube 22 to pass through, and the neck 223 of the second coupling tube 22 is attached to the bottom 253 of the receiving groove 251, when the first coupling tube 21, the movable gasket 231 and the second coupling tube 22 are received and screwed between the female nut 25 and the male nut 24, a distance S is provided between the female nut 25 and the male nut 24, so that the depth H of the receiving groove 251 of the female nut 25 is equal to the distance D1 from the neck 213 to the first flange 214 of the first coupling tube 21, the distance D2 from the neck 223 to the second flange 224 of the second coupling tube 22, the thickness D3 of the movable gasket 231, and the length D4-the distance S of the stud segment 242 of the male nut 24.

Next, referring to fig. 5 to 6, during assembly, the first coupling pipe 21 is inserted into the through hole 243 of the male screw cap 24, the second coupling pipe 22 is inserted into the through hole 252 of the female screw cap 25, the first flange 214 of the first coupling pipe 21 and the second flange 224 of the second coupling pipe 22 are disposed opposite to each other, the washer 23 is embedded into the first flange 214 of the first coupling pipe 21 or the second flange 224 of the second coupling pipe 22, and the male screw cap 24 is manually screwed into the female screw cap 25, so that the movable gasket 231 is abutted between the first flange 214 and the second flange 224. At this time, since the groove depth H of the female nut 25 and the length D4 of the stud section 242 of the male nut 24 are adjusted and regulated in accordance with the distance D1 from the neck 213 of the first coupling pipe 21 to the first flange 214, the distance D2 from the neck 223 of the second coupling pipe 22 to the second flange 224, and the thickness D3 of the movable washer 23, as shown in fig. 6, the groove depth H of the groove 251 of the female nut 25 can be matched with the above specification by extending a ring segment 254 from the female nut 25; as shown in fig. 11, the length of the stud section 242 of the male nut 24 is reduced to make the groove depth H of the receiving groove 251 of the female nut 25 meet the above specification; as shown in fig. 15, the groove depth H of the receiving groove 251 of the female nut 25 can be made to meet the above specification by extending the length of the female nut 25. Therefore, when the male nut 24 cannot be screwed into the female nut 25 manually, the angle for rotating the male nut 24 by one wrench and the female nut 25 by another wrench is a limited value, so that the male nut 24 and the female nut 25 of each connector 2 can be locked at the same position.

Next, referring to fig. 7, in the first embodiment of the present invention, one end surface of the nut section 241 of the male nut 24 is provided with a first mark 245, and one end surface of the female nut 25 is provided with a second mark 255, so that when the connector 2 is assembled, after the male nut 24 is manually screwed into the female nut 25, the male nut 24 is fixed by a wrench, and when the female nut 25 is pulled by another wrench, the female nut 25 can be directly rotated to a position where the second mark 255 corresponds to the first mark 245 with reference to the first mark 245 of the male nut 24, so that the first flange 214 and the second flange 224 are in a state of pressing against the movable gasket 231 (as shown in fig. 8), and thus, whether the male nut 24 and the female nut 25 of each connector 2 are locked at the same position can be rapidly determined.

In addition, in the second embodiment of the present invention, please refer to fig. 9-10, wherein one end surface of the nut segment 241 of the male nut 24 is provided with a first mark 245, one end surface of the female nut 25 is provided with a second mark 255, and the adjacent end surface provided with the second mark 255 is provided with a third mark 256, such that the first mark 245 and the second mark 255 have the same color mark, and the third mark 256 has a color mark different from the first mark 245 and the second mark 255, such that when the male nut 24 is manually screwed into the female nut 25, the first mark 245 of the male nut 24 just corresponds to the third mark 256 of the female nut 25, and at this time, the first flange 214 and the second flange 224 are in a state of contacting the movable gasket 231 (as shown in fig. 11), and if the male nut 24 is manually screwed tightly on the coupling nut 25 but the first mark 245 does not correspond to the third mark 256, it means that the gasket 23 may be missed or the assembled between the first coupling pipe member 21 and the second coupling pipe member 22 or the assembled coupling member 22 23 are not suitable. After the male nut 24 and the female nut 25 are screwed by hand, the male nut 24 is fixed by one wrench, and the female nut 25 is pulled by another wrench until the first mark 245 of the male nut 24 corresponds to the second mark 255 of the female nut 25, so that the first flange 214 and the second flange 224 are in a state of pressing and tightening the movable gasket 231 (as shown in fig. 12), thereby completing the assembly of the joint 2.

Referring to fig. 13-14, in a third embodiment of the present invention, a fourth mark 246 is disposed on an end surface of the male nut 24 adjacent to the first mark 245, and a third mark 256 is disposed on an end surface of the female nut 25 adjacent to the second mark 255, wherein the first mark 245 and the second mark 255 have the same color indication, and the third mark 256 and the fourth mark 246 have the same color indication and are different from the color indication of the first mark 245 and the color indication of the second mark 255. When the male nut 24 is screwed to the female nut 25 by hand, the fourth mark 246 of the male nut 24 corresponds to the third mark 256 of the female nut 25, so that the first flange 214 and the second flange 224 are in contact with the movable gasket 231 (as shown in fig. 15), if the male nut 24 is screwed to the female nut 25 by hand but the fourth mark 246 does not correspond to the third mark 256, it means that the gasket 23 may be missed between the first coupling tube 21 and the second coupling tube 22 or the assembled gasket 23 is not suitable. After the male nut 24 and the female nut 25 are screwed by hand, the male nut 24 is fixed by one wrench, and the female nut 25 is pulled by another wrench until the first mark 245 of the male nut 24 corresponds to the second mark 255 of the female nut 25, so that the first flange 214 and the second flange 224 are in a state of pressing and tightening the movable gasket 231 (as shown in fig. 16), thereby completing the assembly of the joint 2.

Thus, the groove depth H of the female nut 25 and the length D4 of the stud section 242 of the male nut 24 are regulated by matching the distance D1 from the neck 213 of the first coupling tube 21 to the first flange 214, the distance D2 from the neck 223 of the second coupling tube 22 to the second flange 224, and the thickness D3 of the movable gasket 231, so as to limit the angle of the female nut 25 for the wrench to rotate, so that the male nut 24 and the female nut 25 of each joint 2 can be locked at the same position, thereby standardizing the joint 2, and simultaneously preventing the movable gasket 231 from being worn to affect the sealing performance.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
