Problems solved by technology

[0005] Among them, the original needle valve 001 is a small component, and the inside of the original needle valve 001 needs to be equipped with an L-shaped pipe, which makes the structure of the original needle valve 001 complex and difficult to process
In addition, the original needle valve 001 assembled in the oxygen bomb needs to be screwed frequently to adjust the installation position, and the original needle valve 001 with a hollow structure has low structural strength and is not durable

Abstract

The invention discloses an oxygen bomb and an oxygen bomb air exhaust joint. The oxygen bomb air exhaust joint comprises a joint body; a through hole for arranging and sealing the periphery of an oxygen bomb head of the oxygen bomb in a sleeving manner is formed in the middle part of the joint body; and the side wall of the through hole is provided with a joint air pipe which extends in the radialdirection and is arranged in a penetrating way. The oxygen bomb air exhaust joint is suitable for the oxygen bomb assembled by a needle valve with a solid structure and the oxygen bomb head providedwith a connecting air pipe on the side wall, and is used for realizing the vacuumizing operation of the oxygen bomb. During vacuumizing, firstly, the joint body is arranged on the oxygen bomb head ina sleeving manner; then, the needle valve is unscrewed with respect to the oxygen bomb head, so that the oxygen bomb air pipe, the connecting air pipe and the joint air pipe communicate with each other in sequence; and then, the oxygen bomb air exhaust joint is connected with vacuumizing equipment to realize the vacuumizing of the oxygen bomb. After vacuumizing, the needle valve is screwed with respect to the oxygen bomb head, and the oxygen bomb air exhaust joint is taken down. The oxygen bomb air exhaust joint is suitable for the oxygen bomb and the needle valve thereof, and is high in structural strength, corrosion resistance, excellent in tightness and long in service life.

Description

technical field [0001] The invention relates to the technical field of oxygen bombs, in particular to an oxygen bomb suction joint. The present invention also relates to an oxygen bomb, which is suitable for the above-mentioned suction joint of the oxygen bomb. Background technique [0002] The oxygen bomb is a central component of calorimetric devices such as detonation calorimeters. [0003] When the oxygen bomb is in working condition, it needs to fill the interior with 3MPa oxygen, or evacuate the interior into a vacuum state. When the inside of the oxygen bomb is evacuated, the vacuum degree is required to be below 400Pa, and the oxygen bomb is required to withstand a pressure above 30MPa. In addition, the oxygen bomb should also have the characteristics of corrosion resistance, oxidation resistance, high pressure resistance, high temperature resistance and good air tightness. Because the oxygen bomb uses electric ignition when it works, it is also required that the ...
