A fastened steel sleeve for the exhaust pipe of low-temperature refrigeration equipment

Abstract

The invention relates to a fastening type steel sleeve for a gas exhausting pipe of low-temperature refrigerating equipment. The fastening type steel sleeve for the gas exhausting pipe of the low-temperature refrigerating equipment aims at solving the problem that an existing steel sleeve is simply fixed through a simple screw during being fixed, and the steel sleeve cannot be firmly fixed. The fastening type steel sleeve for the gas exhausting pipe of the low-temperature refrigerating equipment comprises a fixing screw, and a first threaded hole which is formed in the steel sleeve, wherein the fastening screw is arranged in the first threaded hole through screw threads, and the fixing screw is in thread connection with a second threaded hole formed in a sealing ring. According to the fastening type steel sleeve for the gas exhausting pipe of the low-temperature refrigerating equipment, a combination structure of a threaded rod, a clamping groove and a clamping block is added; the threaded rod, the clamping groove and the clamping block are coordinated to clamp and fix the steel sleeve and an upper steel pipe again on the basis of fixing through the fixing screw; the structure is reasonable to arrange; the steel sleeve, the upper steel pipe and a lower steel pipe can be firmly fixed by multi-step fixing, and thus the problem that a traditional simple screw cannot realize firm fixing is avoided.

Description

technical field [0001] The invention relates to the technical field of low-temperature refrigeration equipment, in particular to a fastened steel sleeve for an exhaust pipe of low-temperature refrigeration equipment. Background technique [0002] Exhaust pipes of existing low-temperature refrigeration equipment mostly use steel pipe knurling, which makes the welding positioning of copper pipes inaccurate, inconvenient for quick butt joints between copper pipes, and the sealing effect of sleeves is poor. Gradually it cannot meet the production needs, so we make improvements to this and propose a steel sleeve for the exhaust pipe of refrigeration equipment. [0003] The patent application with the notification number CN207454979U discloses a steel sleeve for the exhaust pipe of refrigeration equipment. The steel sleeve for the exhaust pipe of refrigeration equipment is composed of the following structure: sleeve body; upper copper pipe; lower copper pipe; first tightness adjus...
