Tail tube locking device of high-temperature solar evacuated collector tube

Abstract

The invention discloses a tail tube locking device of a high-temperature solar evacuated collector tube. The tail tube locking device of the high-temperature solar evacuated collector tube comprises a tube fitting with a telescopic section, a sealing cover and a driving mechanism, wherein the sealing cover is located at the connecting end of a tail tube of the tube fitting, a center hole used for the tail tube penetrating is formed in the sealing cover with the same axle of an inner hole of the tube fitting, the tube fitting is provided with a first position which is connected with the tube fitting in an air sealing mode and a second position which is separated from the connection in the axial direction, and the driving mechanism is connected with the sealing cover to drive the sealing cover for conversion of the first position and the second position. According to the tail tube locking device of the high-temperature solar evacuated collector tube, the production efficiency can be improved, and the quality of products is ensured.

Description

technical field [0001] The invention relates to a tailpipe clamp used in the high-temperature solar vacuum heat collection pipe exhaust process. Background technique [0002] As is known, solar vacuum heat collecting tubes can be divided into low temperature heat utilization solar vacuum heat collecting tubes, medium temperature solar vacuum heat collecting tubes and high temperature solar vacuum heat collecting tubes according to different heat utilization. -500°C, due to the high temperature, it can be used in thermal power generation and other fields, with broad prospects. [0003] Compared with ordinary heat collecting tubes, high temperature tube products have high cost, large volume and heavy weight. Before exhausting, the assembly process of high temperature tubes and exhaust table is difficult to operate. The glass butt joint of ordinary heat collecting tubes is no longer suitable. The high-temperature tube may be damaged if the operation is slightly improper, resul...

AI Technical Summary

Problems solved by technology

[0005] 1. Inconvenient operation: the high-temperature pipe exhaust equipment is horizontal, the product is placed horizontally, and the product itself is of high quality. It is very inconvenient to lock the tail pipe when exhausting manually, especially when the glass is connected to the glass. difficulty

[0006] 2. Easy to be damaged: the product is placed horizontally. During the exhaust process, the product is heated and expanded, and the position of the exhaust tailpipe will move accordingly. The ordinary locking device is hard-linked, which may easily cause damage to the exhaust tailpipe
