Liner supporting device provided with lengthened power spinning tube, supporting bars and ribbed plates

Abstract

The invention provides a liner supporting device provided with a lengthened power spinning tube, supporting bars and ribbed plates, relating to the technical field of machinery. With the key technology of providing the lengthened power spinning tube, the supporting bars and the ribbed plates, the device is characterized in that the center hole of a liner front head is fixedly connected with the outer end section of a barrel; the inner end of the barrel is fixedly connected with one side of a support ring; the other side of the support ring is fixedly connected with a head; one side of the support ring is also fixedly connected with the inner end of the power spinning tube; the outer end of the power spinning tube is fixedly connected with a manifold valve seat; one ends of the ribbed plates are fixedly connected with the barrel and the other ends of the ribbed plates are fixedly connected with the inner wall of the liner front head; the inner end sections of a gas filled tube, a blow-down tube and an outlet tube pass through and are fixedly connected with tube holes on the support ring and then pass through and are fixedly connected with tube holes on the head; the outer end sections of the three tubes pass through and are fixedly connected with tube holes on the manifold valve seat; a supporting bar end cover hole on the outer end section of the barrel is fixedly connected with a supporting bar end cover; the supporting bar end cover is connected with one ends of the supporting bars in an inlaid manner; and the other ends of the supporting bars are connected with the outer end section of the power spinning tube through push-pressing. The device is used for fixing the liner, has goof fixing effect and reduces heat losses.

Description

technical field [0001] The invention is provided with a liner supporting device with an extended strong coil, a support rod and a rib, and relates to the field of mechanical technology; in particular, it relates to the field of mechanical technology of pressure vessels; in particular, it relates to the field of mechanical technology for supporting the liner of a vehicle-mounted liquefied natural gas storage tank; specifically It relates to the technical field of an inner tank support device provided with an extended strong coil, a support rod and a rib plate. Background technique [0002] At present, the inner tank of vehicle-mounted LNG is supported in the shell by the front and rear supports at both ends. The traditional support has the disadvantages of simple structure and lack of scientific rationality, defects and disadvantages, and it is difficult to achieve the strength corresponding to the actual road conditions in my country Fatigue load requirements, that is, poor a...

Problems solved by technology

[0002] At present, the inner tank of vehicle-mounted LNG is supported in the shell by the front and rear supports at both ends. The traditional support has the shortcomings, defects and disadvantages of simple structure and lack of scientific rationality, and it is difficult to achieve the strength corresponding to the actual road conditions in my country. Fatigue load requirements, that is, poor adaptability to external factors such as overload, vibration, shock, turbulence, anti-collision, and bad road conditions, resulting in poor thermal insulation effect, large heat conduction, and large heat loss during temperature changes. deformation, short service life, and even accidents
