Abstract
The invention discloses a high-strength process pipe inner connector and a manufacturing technology thereof. The high-strength process pipe inner connector comprises a hollow bar and a sealing head. The sealing head is welded to the top end of the hollow bar. The hollow bar is made of a seamless pipe as raw materials. A hollow cavity is formed in the middle of the hollow pipe. A branch through hole is formed in the pipe wall and communicated with the hollow cavity. When the high-strength process pipe inner connector is manufactured, the manufacturing technology comprising the three steps of face forging, welding and turning is adopted. The high-strength process pipe inner connector is easy to manufacture and has more superior using performance. The high-strength process pipe inner connector is still not fractured or deformed under the low temperature, leakage of natural gas in an inner container is not likely to happen, and better safety performance is achieved.
Description
Technical field
The present invention relates to gas cylinder apparatus field, be specifically related to the high strength process duct spigot of pipe in a kind of Joining Technology and the preparation process of this high strength process duct spigot.
Background technique
Along with the rapid growth with automobile pollution that develops rapidly of China's economy, be faced with the dual immense pressure of energy source of car demand and environmental protection.The explored reserve wretched insufficiency of China's oil, and China's motor vehicle emission has become a primary pollution source of city atmospheric environment.Progressively change energy source of car structure, development vehicle clean energy fuel, become the research topic that in China's energy and environment research one is very great and urgent.Due to the proportion lta of rock gas, the rock gas of leakage is diffusion and not gathering in atmosphere easily, uses the Safety performance of gas fuel good, therefore, replaces petroleum product to be one of the most real selection as automotive fuel using rock gas.By the research of scientist, develop LNG automobile and CNG automobile, LNG automobile is compared with CNG automobile, and what LNG fuel gas cylinder was stored is liquid fuel, thus storage capacity is large, continue distance travelled long, LNG gas cylinder due to bunkering pressure low, its Safety performance is better, rock gas is before liquefaction process, through purified treatment, LNG is more clean, and therefore LNG automobile becomes the leading form of automobile market.
Automobile liquefied natural gas bottle is used for the supply of car liquefied petroleum gas fuel.Known automobile liquefied natural gas bottle is equipped with the double layer construction comprising inner bag and urceolus, when the liquified natural gas in this inner bag is discharged, a pipeline need be arranged be used for transmitting rock gas, the two ends of this pipeline need be connected to the spigot be connected with inner bag and the socket be connected with vaporizer, because liquified natural gas is in the state of high pressure in inner bag, because when liquified natural gas is discharged, natural gas via is transferred in output pipeline by spigot can discharge a large amount of energy, especially can be very large to the impact of spigot.The form that traditional spigot adopts solid tubes to be emptied middle and lower part is to transmit rock gas; and be transferred in output pipeline via the through hole on tube wall; and the temperature of liquified natural gas is very low; be generally subzero 196 DEG C; adopt common solid bar to be made into the form of hollow bar, the steel density of solid bar end socket and solid bar tube wall is inadequate, when low temperature like this; often can produce and break and be out of shape, very large potential safety hazard is caused to the use of whole gas cylinder.
The problems referred to above arrange in the process duct spigot on pipe in process and the design and use process in preparation process thereof low temperature cylinder should pay attention to and the problem solved.
Summary of the invention
For above-mentioned Problems existing, the invention provides high strength process duct spigot and preparation process thereof.
Technical solution of the present invention is: high strength process duct spigot, comprise hollow bar and end socket, described end socket is welded on the top of described hollow bar, described hollow bar adopts weldless tube as raw material, it is central cavity in the middle part of described hollow bar, and on the tube wall of described hollow bar, offer branch's through hole, described branch through hole is empty formation from the cylinder outer ring of described hollow bar to central cavity, described branch through hole and described central cavity through.
Further improvement of the present invention is: described end socket is that 304 stainless steels are made.
Further improvement of the present invention is: described central cavity and described branch through hole are all in the form of cylinders.
Further improvement of the present invention is: the preparation process manufacturing high strength process duct spigot, processes in accordance with the following steps: a. satin face: the form by the rod iron surface employing interstitial treatment satin face being used for making end socket being annual ring;
B. empty: the tube wall of hollow bar has been offered branch's through hole;
C. weld: end socket is welded on the top of hollow bar;
D. car is put down: carry out plane treatment to end socket and end socket and hollow bar weld, ensures the texture of surface without densification of end socket.
High strength process duct spigot of the present invention and preparation process thereof, select fixing weldless tube as hollow bar according to specification, and on the tube wall of hollow bar, offer a branch through hole through with central cavity, end socket after satin face is welded on the top of the hollow bar made, the diameter of end socket is identical with the external diameter of hollow bar, again the flat process of car is carried out to end socket, make end socket surface without fine and close texture.Making shaping process duct spigot is arranged on the inner bag of gas cylinder, pipe in technique is inserted branch through hole and is fixed in branch's through hole of spigot, thus liquified natural gas is discharged from inner bag go in pipe via spigot conduction process again.
The invention has the beneficial effects as follows: the present invention is designed with a spigot, the form by emptying into hollow bar in the middle part of solid bar of abandoning tradition, but directly adopt weldless tube as hollow bar, and both convenient and there is no seam due to the periphery of weldless tube, there is more excellent usability.Be in the very low situation of temperature still do not rupture, indeformable.End socket welds the intensity that the processing mode adopting car flat again ensure that end socket with hollow bar, not easily cause the leakage of rock gas in inner bag, and process duct spigot of the present invention makes simple, easy for installation, and the intensity of spigot is very high, has better Safety performance.
