Detailed Description
In order that the invention may be readily understood, a more complete description of the invention will be rendered by reference to the appended drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "disposed" on another element, it can be directly disposed or connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example 1
As shown in fig. 1, the mechanical safety valve comprises a gas distribution valve 1 and a main fire valve 2, wherein the gas distribution valve 1 comprises a shell 11 and a valve core 12 arranged in the shell 11, the shell 11 is cross-shaped and comprises a gas inlet 111, a first outlet 112 and a second outlet 113 which are communicated, the other end is closed, the second outlet 113 is connected with the main fire valve 2, the valve core 1 is cylindrical and is arranged at the intersection of the shell 11, and a rotary handle 13 extending out of the closed end of the shell 11 is also arranged on the valve core 12;
as shown in fig. 2 and 3, an air groove 121 is disposed between the upper and lower bottom surfaces of the valve core 12, the air groove 121 is located at one side of the central axis 122 of the valve core 12, the depth of the air groove does not exceed the central axis 122, an air hole 123 connecting the air groove 121 is disposed on the upper bottom surface of the valve core 12, and the knob 13 is disposed on the lower bottom surface of the valve core 12.
