Abstract
The utility model discloses a charging connector on a head valve. A bump (6) with external thread on the outer circumferential surface is arranged at the junction of a valve body (1) and a pressing nut (8); a connection section (4) is arranged between the bump (6) and the valve body (1); the external diameter of the connection section (4) is less than the external diameter of the bump (6); a shaft shoulder is formed at the junction of the connection section (4) and the bump (6); the charging connector also comprises two limiting pins (5) which are positioned outside the connection section (4) and are symmetrically and radially inserted into one end of the pressing nut (8) close to the valve body (1); and meanwhile, the longest distance of the two limiting pins (5) is less than the diameter of the bump (6). After the structure is adopted, high-pressure gas produced by over-turning the pressing nut during disassembly and assembly of the connector or detection and maintenance by a user can be prevented from being sprayed out so as not to cause safety accidents such as personal injury through interference of the limiting pins and the shaft shoulder of the bump on the valve body.
Description
Technical field
The utility model relates to the technical field of valve, specifically is a kind of for the gas-charging connection on the bottle valve on the driving gas bottle group in the fire-fighting system.
Background technology
At present, used gas cylinder is generally large-scale steel cylinder in the fire-fighting system, is equipped with the electromagnetism bottle valve on the steel cylinder, is used for controlling the circulation of the gas in the steel cylinder.As shown in Figure 1, the electromagnetism bottle valve of prior art comprises valve body 01 and gas-charging connection, and gas-charging connection is installed in a side of valve body 01, and the air admission hole in gas-charging connection and the valve body 01 communicates.Gas-charging connection comprises Connection Block 02, clamping nut 05 and joint body 04, one end of described Connection Block 02 is connected with valve body 01, has the inner chamber 03 that communicates with the air admission hole of valve body in the Connection Block 02, one end of joint body 04 is slidingly fitted in the Connection Block 02, the other end of joint body 04 is connected to the other end, joint body 04 and the Connection Block 02 formation valve of Connection Block 02 by clamping nut 05.But, there is following shortcoming in gas-charging connection on the bottle valve of this structure: because the professional has professional experiences and professional tool in each device of regular detection and maintenance valve, and user's dismounting gas-charging connection privately sometimes, the phenomenon of the clamping nut in the gas-charging connection very easily appears screwing off, therefore, high pressure gas cognition in the valve body is sprayed outside gas-charging connection, thereby damages the security incident of human body.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of and prevents from tearing open the outer spray of the gas that causes and cause injuring the gas-charging connection of the bottle valve that the security incident of human body occurs.
For solving the problems of the technologies described above, the gas-charging connection of the bottle valve that the utility model provides, comprise clamping nut and joint body, in the passage that one end of described joint body is slidingly fitted on the valve body with air admission hole communicates, joint body and valve body form valve, the other end is fixed tightly on the valve body by clamping nut, the junction of described valve body and clamping nut is that outer circumference surface is externally threaded projection, it is linkage section between projection and the valve body, the external diameter of linkage section is less than the external diameter of projection, and the junction of linkage section and projection forms the shaft shoulder; Described gas-charging connection also comprises spacer pin, and the quantity of spacer pin is two, and is positioned at the outside of linkage section, and the spacer pin symmetry radially is plugged on an end of close valve body on the clamping nut, and the maximum distance of two spacer pins is less than the diameter of projection simultaneously.
After adopting above structure, the utility model compared with prior art, have the following advantages: because after in the gas-charging connection assembly, being provided with spacer pin, by the interference of the shaft shoulder of projection on spacer pin and the valve body, thereby revolve clamping nut excessive in the time of can preventing the user at the mounting or dismounting joint or detect maintenance and the outer spray of gases at high pressure that produce injures the security incident generation of human body.
Description of drawings
Fig. 1 is the structural representation of the gas-charging connection of prior art bottle valve.
Fig. 2 is the structural representation of the gas-charging connection of the utility model bottle valve.
Wherein:
In the prior art: 01, valve body; 02, Connection Block; 03, inner chamber; 04, joint body; 05, clamping nut;
The utility model: 1, valve body; 2, air admission hole; 3, passage; 4, linkage section; 5, spacer pin; 6, projection; 7, joint body; 8, clamping nut.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in more detail.
By the structural representation of the gas-charging connection of the utility model bottle valve shown in Figure 2 as can be known, it comprises clamping nut 8 and joint body 7, one end of described joint body 7 is slidingly fitted in the passage 3 that communicates with air admission hole 2 on the valve body 1, joint body 7 forms valve with valve body 1, and the other end is fixed tightly on the valve body 1 by clamping nut 8.Described valve body 1 is that outer circumference surface is externally threaded projection 6 with the junction of clamping nut 8, is linkage section 4 between projection 6 and the valve body 1, and the external diameter of linkage section 4 is less than the external diameter of projection 6, and the junction of linkage section 4 and projection 6 forms the shaft shoulder.Described gas-charging connection also comprises spacer pin 5, and the quantity of spacer pin 5 is two, and is positioned at the outside of linkage section 4, and spacer pin 5 symmetries radially are plugged on an end of close valve body 1 on the clamping nut 8, and the maximum distance of two spacer pins 5 is less than the diameter of projection 6 simultaneously.
The utility model in use, when clamping nut 8 is screwed out and since spacer pin stop that clamping nut 8 can't all be screwed out, thereby guarantee the security used.
