Description
First, technical field
The utility model is related to a kind of secure gas self-closing valve rod cap.
2nd, background technology
After current combustion gas is registered one's residence, gas flow can be controlled using self-closing valve between gas meter, flow meter and gas appliance, certainly
During valve closing use, general self-closing valve extracts operation pull bar to reach the purpose of unlatching by user, and pull bar is and valve body
What interior leather cup was connected, there is external screw thread to be screwed with the internal thread of rod cap on pull bar and link together, using process in user
In, if rod cap misoperation is excessively screwed and tightened, which results in leather cup may stress it is excessive and produce damaged, Jin Erfa
Raw gas leakage, brings potential safety hazard.
Secure gas self-closing valve rod cap, is that one kind is directed to during secure gas self-closing valve use to exempt from pull bar stress
It is excessive and cause that valve inner leather cup is damaged, and a kind of design that can be used safely researched and developed.
3rd, utility model content
The purpose of this utility model is directed to during self-closing valve is used excessive and cause valve inner to exempt from pull bar stress
Leather cup is damaged, and a kind of secure gas self-closing valve rod cap that can be used safely researched and developed.
The purpose of this utility model is achieved like this：A kind of secure gas self-closing valve rod cap, it includes：Cap body,
Mold insert, cap body middle part has a rectangular opening to coordinate with mold insert；There is the raised lock of a circle in mold insert；Cap body passes through mold insert with mold insert
Embedded rectangular opening links together.
During normal use, will not be caused because user excessively tightens rod cap in the case of unwitting and drawn
The connected leather cup of bar is damaged and there is leakage accident.
The utility model has：First, small volume, it is convenient to install, effectively improve the operating efficiency installed and safeguard；2nd, safety
It is reliable, Anti-dismantling；3rd, simple structure, easily uses.
4th, illustrate
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is insert structure schematic diagram of the present utility model.
Accompanying drawing 3 is structure sectional view of the present utility model.
Description of reference numerals：1- cap bodies, 2- mold inserts, A- rectangular openings, the raised locks of B-.
5th, specific embodiment
Below in conjunction with the accompanying drawings and embodiment does furtherly thin description to the utility model.
Referring to the drawings, the utility model secure gas self-closing valve limited cover, it includes cap body 1, and mold insert 2, the middle part of cap body 1 has
One rectangular opening A coordinates with mold insert 2；There are 4 lock B of projection in mold insert 2；Cap body 1 is embedded in rectangle with mold insert 2 by mold insert 2
Hole A links together；After the utility model is assembled in place with pull bar, during normal use, user cannot be dismantled,
The lower part that will not be damaged in valve body is excessively tightened user is ignorant.
