Description

Technical Field

[0001] The utility model relates to the field of semiconductor packaging production, in particular to a welding joint. Background Art

[0002] Semiconductors refer to materials whose electrical conductivity at room temperature is between that of conductors and insulators.

[0003] Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. Whether from the perspective of science and technology or economic development, the importance of semiconductors is enormous. Most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors as the core units.

[0004] In the semiconductor manufacturing process, a large amount of ultrapure water and special chemicals are required, and these substances are often highly corrosive. Due to its excellent corrosion resistance and high purity, the welding joint can ensure the purity of these substances, prevent contamination and leakage, and thus ensure the quality and reliability of semiconductor products;

[0005] The existing welding joints are divided into double-tube joints and triple-tube joints, and the commonly used triple-tube joints can only be used to connect three pipes, not two pipes. Therefore, the triple-tube joint cannot temporarily replace the double-tube joint. A device that can freely replace the triple-tube joint with a double-tube joint is needed to meet the demand for increasing the use range of the triple-tube joint. Therefore, a welding joint is needed. Utility Model Content

[0006] The utility model aims to provide a welding joint to overcome the defect that a three-pipe joint is inconvenient to adjust to a two-pipe joint.

[0007] The technical solution to achieve the above-mentioned purpose is: a welding joint, including a joint body, the side wall of the joint body is connected to three through pipes, the inner side wall of one of the through pipes is connected to a retaining ring, the retaining ring is connected to an outer plate close to the side wall of the joint body, the side wall of the outer plate is provided with a through hole, the outer wall of one of the through pipes is threadedly connected to a sealing member, and the inner side wall of the through pipe symmetrically distributed with one of the through pipes is connected to a flow limiting member.

[0008] Preferably, the sealing member comprises an inner rod, an outer rod and an outer cover, wherein the outer wall of one of the through pipes is threadedly connected to the outer cover, the inner wall of the outer cover is connected to the outer rod, and the end of the outer rod away from the outer cover is connected to the inner rod.

[0009] Preferably, the diameter of the inner rod is smaller than that of the outer rod, the inner wall diameter of the retaining ring is equal to the diameter of the inner rod, the side wall of the outer rod is tightly attached to the inner wall of one of the through tubes, and a sealing strip is connected to the contact point between the outer cover and the through tube.

[0010] Preferably, the side wall of the outer cover is provided with anti-slip grooves.

[0011] Preferably, the sealing member further comprises a connecting hole and a sealing tube, the side wall of the inner rod, the side wall of the outer rod and the side wall of the outer cover are all provided with a connecting hole, and the inner wall of the connecting hole is connected to the sealing tube.

[0012] Preferably, the sealing tube is made of clear glass or transparent plastic, one end of the sealing tube is a closed end, the other end of the sealing tube is an open end, the closed end is hemispherical in shape, and the open end is located in the connecting hole.

[0013] Preferably, the flow limiting component includes a support ring, a baffle and a screw. The inner side wall of the through pipe symmetrically distributed with one of the through pipes is connected with a support ring. The side wall of the support ring is threadedly connected with multiple screws. The side wall of the screw penetrates and squeezes the baffle, and the baffle is in contact with the support ring.

[0014] Preferably, one end of the screw is connected to a cone head, the inner diameter of the support ring is equal to the diameter of the through hole, and the baffle is in the shape of a semicircular plate.

[0015] The beneficial effects of the utility model are:

[0016] 1) Screw the outer cover thread onto the outer wall of one of the through pipes so that the outer cover blocks the port of one of the through pipes. The outer cover drives the outer rod and the inner rod to be inserted into one of the through pipes so that one end of the outer rod is tightly attached to the retaining ring. The outer rod blocks the space between the port of one of the through pipes and the retaining ring. The inner rod is inserted into the retaining ring and abuts against the side wall of the outer plate so that the outer rod and the inner rod block the through hole, thereby blocking one of the through pipes, achieving the effect of changing the three-way joint into a two-way joint, and improving the use range of the three-way joint.

[0017] 2) After the outer cover, outer rod and inner rod block one of the through pipes, if the connecting pipe position connected to the through pipe is opaque, the liquid in the joint body and the connecting pipe cannot be observed. Now, the liquid will pass through the connecting hole into the sealing tube. The sealing tube is made of transparent glass or transparent plastic to facilitate observation of the joint body and the liquid in the connecting pipe.

[0018] 3) By making the inner diameter of the branch ring equal to the diameter of the through hole, when the initial velocity of the liquid is the same, the liquid flow rate is the same when flowing through the two through pipes. By making the baffle plate in the shape of a semicircular plate and the diameter of the baffle plate the same as the outer diameter of the branch ring, the flow rate of the through pipe symmetrically distributed with one of the through pipes is halved to adapt to the situation that when one of the through pipes is closed, the liquid flow is too concentrated in the through pipe symmetrically distributed with one of the through pipes.

[0031] The outer cover 8 is screwed into the outer wall of one of the through pipes 2 so that the outer cover 8 blocks the port of one of the through pipes 2. The outer cover 8 drives the outer rod 7 and the inner rod 6 to be inserted into one of the through pipes 2 so that one end of the outer rod 7 is tightly attached to the retaining ring 3.
