Abstract
The invention discloses a charging joint capable of immediately blocking a inflating channel when discovering leakage, comprising a liquid charging tube, the outer side of which is sheathed with an outer sleeve, one side of the outer sleeve at the outlet end of the liquid charging tube is provided with a clamping jaw, a sealing ring is embedded in the outer wall of the outlet end of the liquid charging tube, a valve top, a spring seat sheathed with a spring and a push tube supporting the spring seat are sequentially arranged in the liquid charging tube from an outlet to an inlet, and an electromagnetic valve is also arranged behind the push tube in the liquid charging tube. Because the back part of the liquid charging tube is provided with the electromagnetic valve, when the leakage is discovered, the invention can immediately block the inflating channel through turning off the electromagnetic valve so as to avoid unnecessary losses of users when the inflating channel is not blocked in time.
Description
Technical field
The present invention relates to the charging joint of liquefied gas at low temp such as LNG Liquefied natural gas, liquid nitrogen.
Background technique
Traditional charging joint is embedded with the seal ring that matches with the bottleneck that will fill bottle together usually on the outer wall of topping up pipe outlet end at present.In the actual using process, usually because uncertain factors such as misoperation cause leakage, leakage sometimes is very slight, is difficult for discovering, and has so just buried potential safety hazard; Most importantly: in case find to leak, can not can only make the valve top stretch out forward by charging joint is taken off, block filling channel at once with the filling channel blocking-up.So just caused unnecessary loss to the user.
Summary of the invention
Technical problem to be solved by this invention is: a kind of charging joint that just can block filling channel at once of finding to leak is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: charging joint, comprise the topping up pipe, the outside of topping up pipe is set with overcoat, a side that is enclosed within topping up pipe outlet end outward is provided with claw, be embedded with seal ring on the outer wall of the outlet end of topping up pipe, from being exported to the importer to setting gradually valve top, be set with the spring seat of spring and shore the ejector sleeve of spring seat, the back at ejector sleeve in the topping up pipe also is provided with solenoid valve in the topping up pipe.
The invention has the beneficial effects as follows: the present invention is provided with solenoid valve at the rear portion of topping up pipe, when finding to leak, by turn-offing solenoid valve, can block filling channel at once, thereby avoid owing to can not in time block and fill passage and cause unnecessary loss to the user.
