Precision is high, and adaptable and safety is good, improves the service performance of gas pipeline self-closing valve.
In the present embodiment, the floating seal bolt 32 include with 30 bottom end of valve rod assembly be attracted connection strong disk 320, with
The floating bolt 321 of strong 320 bottom end of disk mating connection and the gasket 322 for being connected to 321 bottom end of floating bolt, the floating bolt
321 outer wall and adjusting spiral shell disk 313 is cooperatively connected, and the strong disk 320 is attracted with 313 spacing of spiral shell disk is adjusted, the gasket
322 contradict connection with accent cooperation in inlet chamber 10, pass through setting connection between the preferred strong disk 320 and floating bolt 321
Screw connection, the convenient connection to strong disk 320 and floating bolt 321 positions, while the gasket 322 passes through strong disk 320
With the adhesive action for adjusting spiral shell disk 313, and then realizes and contradicted with the sealing of the interior accent of inlet chamber 10 or separating action.
In the present embodiment, the valve rod assembly 30 includes stem body 300, the drawing cap for being connected to 300 upper end of stem body
301, the carrying handle 302 drawn on 301 outer wall of cap, the nut 303 and and spiral shell that are connected on 300 outer wall of stem body are set
The membrane pressure piece 304 that 303 bottom end of cap is cooperatively connected, the nut 303 compress membrane pressure piece 304 and diaphragm 4 and stem body 300 are pasted
Connection is closed, the carrying handle 302 is cooperatively connected with valve deck 2, and the valve rod insertion draws cap 301 to connect, and facilitates and cap 301 is drawn to cooperate
Stem body 300 drives floating seal bolt 32 to act, and carries out combustion gas opening and closing control.
In the present embodiment, the diaphragm 4 is cooperatively connected with 1 upper surface of valve body and is additionally provided on diaphragm 4 with valve deck 2 with combined pressure

Suffer from.
In the present embodiment, 10 inner wall of inlet chamber is connected with filter screen 15, the setting of the filter screen 15 can into
The combustion gas for entering inlet chamber 10 is filtered, and impurity is effectively avoided to enter valve body 1, is played keeping device and is improved the use of valve body 1
The effect in service life.
In the present embodiment, the fuel gas ball valve for controlling the opening and closing of 11 accent outlet of outlet chamber is additionally provided on the outlet chamber 11
13, the fuel gas ball valve 13 can the outlet again to 1 outlet chamber 11 of valve body control, improve the safety that uses of self-closing valve
Property.
It is of the invention that the specific working principle is as follows:
For the varying environment requirement that self-closing valve uses, the requirement of gas flow is also different, when needs are according to combustion gas needed for user
When flow is configured, turn adjusts spiral shell disk 313 and adjusts the relative position of base circle 12, due to adjusting the flow tune on base circle 12
Knothole 14 adjusts the bigger of the exposing of flow regulating orifices 14 on base circle 12, therefore gas flow when revolving on adjusting spiral shell disk 313
Can be bigger, it is on the contrary then small, and then realize that the adjusting to gas flow controls；
When self-closing valve is not used, diaphragm 4 is in no deformation level normal orientation, and stem body 300 can be bonded with diaphragm 4 and bottom
End is attracted with strong disk 320, while strong disk 320 is also at spacing attracting state with spiral shell disk 313 is adjusted, and is kept in the above movement
While stabilization, gasket 322 is contradicted at the accent inside inlet chamber 10, and valve is in off state at this time；
When having combustion gas to pass through in pipeline and 1 air pressure inside of valve body is normal, carrying handle 302 makes that cap 301 is drawn to drive stem body
300 drive drawing cap 301 above to mention, and floating seal bolt 32 can be by connecting, so that floating seal bolt 32 with the actuation of stem body 300
The whole stem body 300 of cooperation upwards links, and gasket 312 is detached from the accent inside inlet chamber 10,321 bottom end of floating bolt at this time
The inner wall limit of spiral shell disk 313 can be adjusted by resisting, diaphragm 4 is heaved under the air pressure for entering combustion gas, and then keeps out gaseity,
The combustion gas of normal use at this time enters from inlet chamber 10, by 10 accent of inlet chamber and adjusts the flow regulating orifices 14 on base circle 12
Enter lower chamber afterwards, and then enter outlet chamber 11, and due to carrying handle 302 and draws between cap 301 there are free gap, because
Carrying handle 302 is mentioned on this, is made to draw cap 301 to drive and is mentioned 321 bottom end of floating bolt on stem body 300 and floating seal bolt 32 and support
After the inner wall limit for firmly adjusting spiral shell disk 313, when unclamping carrying handle 302, carrying handle 302 can not dropped back into original by external force
Position, self-closing valve are in normal operating condition；
In a state of use, when 10 admission pressure of inlet chamber increases, diaphragm 4 can be under the effect of the pressure by just for self-closing valve
The state of being often used continues up jack-up, forces stem body 300 while matching and close top, the power that diaphragm 4 jacks up upwards at this time is greater than
The suction-combining force of stem body 300 and strong disk 320 adjusts the limit of spiral shell disk 313 since floating bolt 321 resists, forces stem body
It is disconnected between 300 and strong disk 320, strong disk 320 can make strong magnetic due to connecting with the actuation for adjusting spiral shell disk 313 itself
Disk 320 and adjusting spiral shell disk 313 are in spacing attracting state, while gasket 322 can resist the interior accent of inlet chamber 10 again, make
Blast tube cutting between inlet chamber and outlet chamber pushes drawing 301 return of cap, 300 bottom end of stem body after handling On The Problem Of Overpressure
With strong disk 320 again due to the suction-combining force is attached, self-closing valve is adjusted to initial closed state；
Start self-closing valve or self-closing valve in a state of use when above mentioning carrying handle 302, when gas supply conduit pressure occurs under-voltage, film
Piece 4 can be due to the inadequate destruction of edition type of pressure, and the power that diaphragm 4 jacks up upwards is less than the actuation of strong disk 320 with adjusting spiral shell disk 313
Power forces strong disk 320 to be attracted with 313 spacing of spiral shell disk is adjusted, and stem body 300 cooperates floating seal bolt 32 to decline, so that floating
The gasket 322 of 32 bottom of dynamic sealing bolt blocks 10 accent of inlet chamber again, and combustion gas can not pass through, when admission pressure meets normally
After use demand, it can normally start and restore the above normal operating condition；
In the state that inlet chamber 10 is in normal air inlet, there is bursty state beyond normal use gas flow in outlet chamber 11
When, decompression in lower chamber, diaphragm 4 can be due to the inadequate destruction of edition type of pressure at this time, and the power that diaphragm 4 jacks up upwards is less than strong disk
320 with the suction-combining force that adjusts spiral shell disk 313, force strong disk 320 to be attracted with 313 spacing of spiral shell disk is adjusted, the cooperation of stem body 300 is floating
Dynamic sealing bolt 32 declines, so that the gasket 322 of 32 bottom of floating seal bolt blocks 10 accent of inlet chamber again, combustion gas can not lead to
It crosses, realizes the effect of super flow cutting, improve the safety that gas pipeline self-closing valve uses.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, is made all within the spirits and principles of the present invention
Any modifications, equivalent replacements, and improvements etc. out should all include within the scope of the present invention that the content of the present specification should not manage
Solution is limitation of the present invention.
