Abstract

The invention relates to a self-drilling exhaust screw easy to use, and belongs to the technical field of water circulation system equipment. When exhaust devices are additionally arranged in the later period of network construction, the technological process is complex, the workload is high, the cost is high, water resource waste is prone to being caused, such technical problems are solved with the self-drilling exhaust screw easy to use. According to the scheme for solving the technical problems, the self-drilling exhaust screw easy to use comprises a self-drilling screw body and a sealing gasket. An annular sealing gasket groove is formed in the bottom surface of the head of a self-drilling screw body in the circumferential direction of the top of a screw rod. The sealing gasket is installed in the annular sealing gasket groove. The screw rod of the self-drilling screw is provided with an exhaust channel in the direction of a central axis, an air inlet of the exhaust channel is formed in the bottom of the screw rod of the self-drilling screw rod, and an air outlet of the exhaust channel is formed in the side wall of one side of the upper portion of the screw rod of the self-drilling screw. The head of the self-drilling screw body is a hex screw head. The self-drilling exhaust screw easy to use has the advantages of being reasonable in structural design, safe to use, easy andquick to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of water circulation system equipment, and in particular relates to a simple drill tail exhaust screw. Background technique [0002] During the construction process of the pipeline network of the water heating system, the water circulation air conditioning system and other water circulation systems, there will be fluctuations in the pipeline and the up and down bending of the pipeline. During the use of the undulating and upward arching part of the pipeline and the upward bending part of the pipeline, some air will remain. This part of the air cannot be completely removed in time and effectively, and local air resistance will occur. Therefore, it is necessary to install an exhaust device for exhaust during construction. gas. However, in actual construction, it is often the case that the exhaust device is not added or is forgotten to be installed. If the exhaust device is to be added later, all the water in ...
