Description

Connectors for conducting chemicals

This creation is related to a type of connector, especially the vacuum-connected radially sealed connector used in the semiconductor optoelectronics industry.

Press, Vacuum Coupling Radius Seal (VCR) is commonly used in the semiconductor optoelectronics industry to conduct gas or liquid connectors for chemicals. Please refer to Figure 1 for details. The connectors (1) mainly include A first connecting pipe piece (11), a second connecting pipe piece (12), a gasket (13), a male nut (14) and a female nut (15). Wherein, the two ends of the first connecting pipe piece (11) and the second connecting pipe piece (12) respectively form piping ends (111), (121) and sealing ends (112), (with flanges (113) and (123)). 122), and the washer (13) includes a movable washer (131), and is formed on the male nut (14) and the female nut (15) for the first connecting pipe (11) and the second connecting pipe (12) to pass through Let the perforations (141), (151).

When assembling, please refer to Figure 1 and cooperate with Figure 2. It is to insert the first connecting pipe piece (11) and the second connecting pipe piece (12) on the male nut (14) and the female nut ( 15) perforate (141), (151), and set the flange (113) of the first connecting pipe (11) and the flange (123) of the second connecting pipe (12) opposite to each other, and put the gasket (13) Fit the flange (113) of the first connecting pipe (11), and then manually screw the male nut (14) to the female nut (15), so that the movable washer (131) abuts against the first connecting pipe Between the flange (113) of (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), use the male nut ( 14) Draw a reference line (L) with one of the corresponding end faces of the female nut (15) as the reference plane, then fix the male nut (14) with a wrench, and turn the female nut (15) with another wrench to rotate About 1/8~1/6 turns, make the reference line (L) of the male nut (14) and the female nut (15) separated by 45°~60°, and then by the flange of the first connecting pipe (11) (113) The flange (123) of the second connecting pipe (12) is pressed against the movable gasket (131) to realize the sealing state of the joint (1) pipeline (as shown in Figure 3).

However, the force applied to the joint (1) by different operators or even the same operator each time using the wrench is not consistent. Therefore, the conventional assembly method can only regulate the angle range of the wrench to the female nut (15) and cannot Make each joint (1) locked in a fixed position, so that the flange (113) of the first connecting pipe (11) and the flange (123) of the second connecting pipe (12) are pressed against the movable gasket (131) The power of) is not consistent. In practice, it has also been found that operators with greater force may cause the movable gasket (131) to wear or even deform due to the larger rotation angle of the female nut (15) by the wrench, making the joint (1) unable to be replaced after disassembly. Assembled and used, obviously there are shortcomings to be improved.

In order to improve the above-mentioned shortcomings, US Publication No. US05058935A discloses a "fluid fitting with torque suppression device", which is provided with an annular drive member between the female nut and the first coupling member, and the annular drive member A tapered angle is formed, and a groove with a tapered angle is provided on the male nut. When the female nut is screwed with the male nut, the groove of the male nut is wedged with the annular drive member to limit the female nut Transmission of rotational force.

In addition, the US Patent Publication No. US06308994B1 discloses a "fluid fitting with torque suppression device", which is formed with a groove at the end of the first coupling member or the second coupling member, and a containing ring is installed in the groove And the torque suppression component of the thrust member, when the female nut and the male nut are screwed together, the torque suppression component is used to limit the transmission of the rotational force of the female nut.

In view of the fact that the conventional assembly method of joints cannot lock each joint in a fixed position, resulting in the inconsistent force of the two connecting pipes pressing on the movable gasket, there is obviously a lack of improvement.

Therefore, the purpose of this creation is to set scales on the male nut and female nut separately, so that the male nut and female nut of each joint can be locked in a fixed position by the alignment scale, so as to realize the standardization of the joint The purpose.

In order to achieve the foregoing purpose, the present invention provides a joint for conducting chemicals, which includes a first connecting pipe, a second connecting pipe, a gasket, a male nut and a female nut, wherein the first connecting pipe And the second connecting pipe respectively form a sealing end with a first flange and a second flange, and the gasket includes a movable gasket, and the movable gasket is arranged between the first flange and the second flange, and the male screw The cap and the female nut respectively form a through hole for the first connecting tube and the second connecting tube to pass through. The feature is that the male nut forms a nut section, and at least one first end is provided on one end of the nut section One scale, and at least one second scale is provided on the end surface adjacent to the first scale, and at least one third scale is provided on one end surface of the female nut, and at least one The fourth scale, when the second scale corresponds to the third scale, the first flange and the second flange are in contact with the movable gasket, and when the first scale corresponds to the fourth scale, the first flange and the second convex The edge squeezes tightly on the movable gasket, so that the joint is in a sealed state.

Based on the above, the first and second scales provided on the end face of the male nut and the third and fourth scales provided on the end face of the female nut are used as the reference for joint locking, so that the operator can lock the female nut with bare hands. When the second scale corresponds to the third scale, and the female nut is turned to the fourth scale corresponding to the first scale with a wrench, it can be accurately judged that the connector is indeed locked, so that the male nut and female nut of each connector The nuts can be locked in the same position to realize the standardization of the joints and avoid the wear of the movable gasket and affect the sealing performance.

In order to achieve a more complete disclosure of the technical content for the purpose of creation, I will elaborate on the following content, and please also refer to the disclosed diagram and drawing number:
