Problems solved by technology
Hydrochloric acid is a volatile and corrosive liquid. On the one hand, there is a small amount of acid mist pollution during the duration in the funnel. On the other hand, hydrochloric acid is easily polluted by floating dust when exposed to the air. Hydrochloric acid contaminated by impurities is generated in the lead-acid battery. Trace chemical reaction, its side effect is to affect product quality and reduce service life

Embodiment Construction
[0016] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0017] figure 1 The closed acid injection nozzle shown includes a pipe body 1, a funnel 2 and a sealing ring 3, and the upper pipe body 1 and the lower funnel 2 are coaxially sleeved and sealed for connection. The pipe body 1 is a straight-through pipe, and the upper end surface is centered with an interface 1.2 communicating with the inner cavity, and the ring interface 1.2 is provided with such figure 2 As shown, there are two coaxial circular spigots 1.1 protruding upwards, and a sealing ring 3 is embedded in the circular spigots 1.1 to form a plane sealing structure. On the same circumference of the inner hole wall of interface 1.2, there are such figure 2 , image 3 The shown two opposite single-sided internal spiral wedges 1.3, the slope of the right-handed single-sided internal spiral wedge 1.3 faces downward, and the helix ...

The invention discloses a closed acid injection adapter. The closed acid injection adapter comprises a pipe body, a funnel and sealing rings, wherein the pipe body and the funnel are coaxially sleeved and connected into a whole in a sealing way; an interface is formed in the center of the upper end surface of the pipe body; two circular seam allowances are formed around the interface; the sealing rings are embedded into the circular seam allowances to form a sealing structure; two sections of one-sided internal threaded wedges which are erected oppositely are arranged on the same circumference of the inner hole wall of the interface; the funnel is a reducer pipe with a big upper part and a small lower part; a male connector is arranged at the bottom of a flow-guiding pipe on the lower part; two sections of one-sided external threaded wedges which are erected oppositely are arranged on the same circumference on the two sides of the outer wall of the male connector; and the sealing rings are embedded into annular slots on the one-sided external threaded wedges to form a locking and sealing structure. The interface and the male connector are matched with a storage battery acid injection hole in specification; an acid injection gun connector is inserted into the interface of the pipe body and tightly screwed; under a sealed condition, the problems of acid mist spilling and impurity mixing can be avoided; and the closed acid injection adapter is high in acid injection efficiency and good in acid injection quality.
Description
technical field [0001] The invention relates to a pipeline tool, in particular to a connecting pipe for injecting acid into a lead-acid storage battery. Background technique [0002] Acid injection is a necessary procedure in the production process of the lead-acid battery, and the prior art generally injects hydrochloric acid into the lead-acid battery by means of a funnel. The opening is a significant structural feature of the funnel, which can improve the perfusion conditions and increase the efficiency of acid injection under the funnel diversion. Hydrochloric acid is a volatile and corrosive liquid. On the one hand, there is a small amount of acid mist pollution during the duration in the funnel. On the other hand, hydrochloric acid is easily polluted by floating dust when exposed to the air. Hydrochloric acid contaminated by impurities is generated in the lead-acid battery. Trace chemical reaction, its side effect is to affect product quality and reduce service life. ...
