Multiple original tension simultaneously pushes the opening valve 105 of slide bar 104 open, opens blast tube by simultaneously rotation turn switch 8 down again, i.e.,
Can be achieved to reset, after blast tube is closed, blast tube will not automatic switching on, need artificial to push rotary switch 8 again and turn
Dynamic rotary switch 8, is connected to blast tube, normal use combustion gas just may be implemented.
Embodiment 2
As shown in fig. 6-7, the present invention provides a kind of multifunctional fuel self-closing spherical valve, the structure of the present embodiment and embodiment 1
Essentially identical, something in common repeats no more, the difference is that, outlet mouth of pipe is spirally connected with pagoda cucurbit mouth Green's connector, pagoda
Cucurbit mouth Green's connector is suitable for conveying low-pressure fuel gas for connecting hose, when pipe gas being reduced with gas peak pressure or
When ultralow pressure, user's still normal use combustion gas；Green's washer 13 and Green's locking cap 14 are installed in the inner coaxial of valve deck 11,
The airtightness of blast tube is effectively increased, conveying high-pressure combustion gas is suitable for.
Working principle
When pipe gas instantaneous pressure superpressure, pipe gas flow moment super stream, sebific duct or metal bellows occur micro- leakage,
Occur falling off when damaged gas leakage, sebific duct or metal bellows occur in sebific duct or metal bellows, sebific duct or metal bellows occur
When cracking gas leakage, sebific duct or metal bellows are broken by the teeth by mouse, there is imbalance in the pressure or flow of inlet end and outlet side,
The thrust of first spring 103 can not push slide bar 104 open, and when the first spring 103 compresses, the moment that slide bar 104 pushes valve 105 is closed
Outlet side is closed, the blast tube in valve ball 101 has been blocked；After blast tube is closed, blast tube can not be automatically opened again, it is necessary to
Rotary switch 8 is pressed downwards, and the first spring 103 gradually reduces under the effect of the pressure, by children's lock card 5 from cross limiting slot 1001
By the bottom for arriving 360 degree rotation groove, the top of the axis of children's lock card 5 and limiting card 6 are connected, by 8 turns of rotary switch
It is 90 degree dynamic, it is in close state rotary switch 8；After rotary switch 8 is closed, the first spring 103 is in compressive state, upwards
Children's lock card 5 is pushed, until bulge-structure is engaged with convex edge, prevents children's lock card 5 from continuing to move up, while making child lock
Card 5 is clamped with cross limiting slot 1001, prevents children from turning rotary switch 8；When rotary switch 8 is in close state, valve ball
Pressure recovery inside 101 is to equilibrium state, and the first spring 103 pushes slide bar 104 open, and slide bar 104 drives valve 105 to open valve ball
Rotary switch 8 is pressed downwards so that the inlet end of valve ball 101 is connected to again with outlet side in 101 outlet side, and the first spring 103 exists
It gradually reduces under the action of pressure, children's lock card 5 is pressed from cross limiting slot 1001 to the bottom of 360 degree rotation groove, children
The top of the axis of lock card 5 and limiting card 6 connect, and rotary switch 8 is rotated 90 degree, rotary switch 8 is made to be in opening state
State, user can normal use combustion gas；After rotary switch 8 is opened, the first spring 103 is in compressive state, pushes up
Virgin lock card 5 prevents children's lock card 5 from continuing to move up until bulge-structure is engaged with convex edge, at the same make children's lock card 5 and
Cross limiting slot 1001 is clamped, and prevents children from turning rotary switch 8.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
