The solution is as follows: a simple drill tail exhaust screw, wherein: comprises a self drilling screw and a sealing gasket; annular sealing gasket grooves are formed in the bottom surface of the head of the self-drilling screw and in the circumferential direction of the top of the screw rod; the sealing gasket is arranged in the annular sealing gasket groove; the drill tail screw rod is provided with an exhaust passage along the direction of the central axis, an air inlet of the exhaust passage is arranged at the bottom of the drill tail screw rod, and an air outlet of the exhaust passage is arranged on the side wall of one side of the upper part of the drill tail screw rod. The head of the self drilling screw is an outer hexagonal screw head. The invention has the advantages of reasonable structural design, safe use, simple and quick operation and the like.
Description
Technical Field
The invention belongs to the technical field of water circulation system equipment, and particularly relates to a simple exhaust screw with a drill tail.
Background
The conditions of pipeline lodging and pipeline up-and-down bending can occur in the pipe network of the water heating system, the water circulation air conditioning system and other water circulation systems in the construction process. The pipeline undulates and arches the part and turns over curved part in the pipeline and have some air to remain in the use, and this part air can't be in time effectual get rid of completely, will locally appear the air lock phenomenon, consequently need install exhaust apparatus additional when the construction and exhaust. However, during actual construction, the exhaust device is often not installed or forgotten to be installed, and if the exhaust device is to be added at a later stage, all water in a pipe network must be discharged to be installed additionally, so that a great amount of time cost and labor cost are increased while a great amount of water resources are wasted.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a simple drill tail exhaust screw, and solves the technical problems of complex process, large workload, high cost, easy water resource waste and the like existing in the process of adding an exhaust device at the later stage of a pipe network.
In order to solve the problems, the technical scheme of the invention is as follows: a simple drill tail exhaust screw, wherein: comprises a drill tail screw and a sealing gasket;
annular sealing gasket grooves are formed in the bottom surface of the head of the self-drilling screw and in the circumferential direction of the top of the screw rod; the sealing gasket is arranged in the annular sealing gasket groove;
the drill tail screw rod is provided with an exhaust passage along the direction of the central axis, an air inlet of the exhaust passage is arranged at the bottom of the drill tail screw rod, and an air outlet of the exhaust passage is arranged on the side wall of one side of the upper part of the drill tail screw rod.
Furthermore, the head of the self drilling screw is an outer hexagonal screw head.
By adopting the technical scheme, the tail part is in a drill tail shape, auxiliary processing is not needed, the operation of drilling, tapping, locking and sealing can be directly finished at one time on the system pipeline under pressure, the construction time is greatly saved, the construction labor cost is reduced, and the operation is safe, simple and quick; after the construction is finished, air in the pipeline is exhausted through an exhaust passage of the drill tail exhaust screw, the threaded hole and an upper exhaust passage of the conical exhaust screw.
Compared with the prior art, the invention has the advantages of reasonable structural design, safe use, simple and quick operation and the like.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention is described in further detail below with reference to the figures and examples.
A simple drill tail venting screw as shown in fig. 1, wherein: comprises a self drilling screw 1 and a sealing gasket 2;
the bottom surface of the head of the self-drilling screw 1 and the circumferential direction of the top of the screw rod are provided with annular sealing gasket grooves 3; the sealing gasket 2 is arranged in the annular sealing gasket groove 3;
an exhaust passage 4 is arranged on the screw rod of the self drilling screw 1 along the direction of the central axis, an air inlet of the exhaust passage 4 is arranged at the bottom of the screw rod of the self drilling screw 1, and an air outlet of the exhaust passage 4 is arranged on the side wall of one side of the upper part of the screw rod of the self drilling screw 1.
The head of the self drilling screw 1 is an outer hexagonal screw head.
The use process of the invention is as follows:
when in use, the invention is installed on a pipeline at a position where air exhaust is needed in a pressurizing way;
when the exhaust is needed, the self drilling screw 1 is unscrewed upwards, and the air in the pipeline is exhausted through the exhaust passage 4 of the self drilling screw 1 and the gap between the threads; and after the air exhaust is finished, screwing down the self drilling screw 1.
