Detailed Description
The following embodiments of the present invention are provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
Example (b):
a self-closing valve quick installation kit is shown in attached figures 1-4 and comprises a pipe hoop 1 and an outer screw 2, wherein the outer screw 2 comprises a connecting part 2.1, a cylindrical connector 2.2 and a conical connector 2.3 which are arranged at two end parts of the connecting part 2.1, the cylindrical connector 2.2 and the conical connector 2.3 are mutually communicated, an outer pipe thread 2.4 matched with a pipe opening end 3.1 of a self-closing valve 3 is arranged on the surface of the cylindrical connector 2.2, an outer cone thread 2.5 with the opposite rotation direction of the outer pipe thread 2.4 is arranged on the surface of the conical connector 2.3, the pipe hoop 1 is of a hollow structure, a first inner cone thread 1.1 matched with the outer cone thread 2.5 is arranged on the inner wall of one end of the pipe hoop 1, and a second inner cone thread 1.2 matched with a natural gas pipeline 4 is arranged on the inner wall of the other end of the pipe hoop 1.
Preferably, the outer pipe thread 2.4 is a reverse-rotation outer pipe thread, the outer cone thread 2.5 is a forward-rotation outer cone thread, the first inner cone thread 1.1 is a forward-rotation inner cone thread, and the second inner cone thread 1.2 is a reverse-rotation inner cone thread, in the installation process, the cylindrical connector 2.2 of the outer screw 2 is fixedly connected with the pipe orifice end 3.1 of the self-closing valve 3, and considering that the thread of the pipe orifice end 3.1 of the self-closing valve 3 is generally a 6.5 thread, in the novel structure, the outer pipe thread 2.4 is a 7 thread, so that on the basis of ensuring the connection strength of the cylindrical connector 2.2 and the pipe orifice end 3.1, the damage of a filter screen of the self-closing valve 3 and the failure of the self-closing valve caused by the fact that the cylindrical connector 2.2 is screwed into the pipe orifice end 3.1 to be too deep, and the filter screen is blocked can be prevented; then, one end of the pipe hoop 1 provided with the second inner tapered thread 1.2 is screwed into the natural gas pipeline 4, the pipe hoop 1 is screwed into the natural gas pipeline 4 to a depth that the pipe hoop 1 does not fall off the natural gas pipeline 4, then the tapered connector 2.3 of the outer screw 2 is aligned with one end of the pipe hoop 1 provided with the first inner tapered thread 1.1, the pipe hoop 1 is rotated anticlockwise, the pipe hoop 1 is screwed and fixed with the tapered connector 2.3 and the natural gas pipeline 4, finally the natural gas pipe is installed at the gas pipe end 3.2 of the self-closing valve 3, and the installation of the self-closing valve 3 is completed.
Can see through the aforesaid, through this novel connecting piece installation self-closing valve 3 that provides, need not rotate self-closing valve 3 in the installation, through rotatory ferrule 1 alright with fixed self-closing valve 3, need not install elbow spare 5 additional at natural gas line 4 and increase and the wall body between the installation clearance, not only practiced thrift time and labour, but also practiced thrift installation cost.
