Embodiment

[0041] like figure 1 As shown, the present invention includes a male body 2 , a female body 1 , an outer ring 3 , a valve core 5 , a spring 6 , and seals 7 , 8 , and 9 .

[0042] The outer ring 3 is set on the front end of the female body 1, and the outer ring 3 cooperates with the male body 2 inserted into the female body 1 through threads, so as to fasten and lock the male body 2 and the female body 1;

[0043] The outer wall surface of the main body 1 of the female head is provided with a retaining spring 10, which is used to cooperate with the outer ring 3 to realize the stop of the outer ring 3;

[0044] Each of the male body 2 and the female body 1 has an air guide channel, and the two air guide channels have the same shape;

[0045] An O-shaped seal 7 is provided at the opening positions of the two air guiding channels;

[0046] The female head main body 1 is also provided with a connecting channel communicating with the front end of the air guide channel;

[0047] T...

Abstract

The invention discloses a special attachment joint for introducing ammonia gas and ammonia water. The special attachment joint comprises a male main body, a female main body, an outer ring, a valve core, a spring and a sealing element. The outer ring sleeves the front end of the female main body and is matched with the male main body inserted into the female main body by use of threads, and therefore, the male main body and the female main body can be fastened and locked; a gas guide channel is formed in the male main body and the female main body, and the two gas guide channels are the same in shape; a valve core is mounted in each of the two gas guide channels by use of a guide part and a spring; the front end of the valve core extends out of the opening of the gas guide channel. The special attachment joint is simple in structure and reasonable in design; the male main body and the female main body are sealed twice no matter in a disconnected state and a connected state, and an ammonia storage tank can be used more safely.

Description

technical field [0001] The invention relates to a pipeline connection joint, in particular to a special connection joint for passing ammonia gas and ammonia water. Background technique [0002] Ammonia is one of the most produced inorganic compounds in the world and has a wide range of applications. For example, in the process of tail car treatment, ammonia gas can be used to treat the tail gas. Specifically, the gas emitted by automobile exhaust mainly includes nitrogen oxides. If these nitrogen oxides are not treated, they will have a great impact on the environment if they are directly discharged into the air. In order to make automobile emissions more environmentally friendly, general automobile exhaust will react with ammonia gas before being discharged, and ammonia gas is stored in an ammonia storage tank, and then exported to react with automobile exhaust gas when needed. [0003] In the actual use of ammonia gas, because it is an irritating gas with small molecules...
