Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, a detachable multi-chamber connector sealing structure, including connecting rod 1, joint 2, sealing ring 3, thread nipple 4, separator 5, spring washer 6 and lock nut 7; wherein the joint 2 will be connected The rod 1 is connected with the threaded nipple 4, and then the connecting rod 1, the joint 2 and the threaded nipple 4 are assembled together to form a connecting rod. The sealing ring 3 is set on the threaded nipple 4, and the sealing ring 3 is tightly attached to the joint 2 The side of the joint 2 that is close to the sealing ring 3 is a sealing surface formed by machining, which has a certain degree of smoothness, which can ensure that the sealing ring 3 is well sealed when it is close to the side of the joint 2; 3 Insert it from the end of the threaded nipple 4 and set it close to the sealing ring 3. The loc...

Abstract

The invention discloses a detachable multi-cavity connecting piece sealing structure. The detachable multi-cavity connecting piece sealing structure comprises a connecting rod, a connector, a sealing ring, a threaded nipple, a baffle, a spring gasket and a locking nut, wherein the connecting rod is connected with the threaded nipple through the connector; the connecting rod, the connector and the threaded nipple are assembled together, so that a connecting rod piece is formed; the sealing ring sleeves the threaded nipple, and the sealing ring is tightly attached to a lateral side of the connector; the baffle sleeves the end part of the threaded nipple and is tightly attached to the sealing ring; the locking nut is in threaded connection with the threaded nipple; and the spring gasket is arranged between the baffle and the locking nut. The detachable multi-cavity connecting piece sealing structure disclosed by the application can penetrate through sealed container cavities communicate with each other without leakage, and the detachable structure of the cavities to be sealed is not damaged, so that the detachable multi-cavity connecting piece sealing structure has a practical effect of communicating two independent cavities in limited space.

Description

technical field [0001] The invention relates to the technical field of workpiece sealing, in particular to the sealing structure of a detachable connecting piece (such as a connecting rod or a tube) that needs to be positioned in a closed cavity. Background technique [0002] At present, the workpiece needs to be positioned and installed at a specific position in a confined space, or it is permanently fixed after being in place, such as the tube-through and fixing of the heat exchange tube of a fixed tube-sheet heat exchanger. Once fixed, this method cannot be disassembled, such as If it is damaged, it cannot be replaced; or the method of fixing first and then positioning is adopted, such as the fixing of the overflow pipe and the tube sheet and the positioning of the catheter tube in the cyclone separation equipment. This positioning is very inconvenient. When multiple workpieces need to be It is more difficult to locate. Contents of the invention [0003] The object of ...
