Embodiment:
As shown in attached drawing 1 to attached drawing 5:
The utility model provides a kind of natural gas valve for facilitating folding, including valve body 1, handwheel 2, rotation seat fagging
3, threaded rod 4, apical axis 5, connecting rod 6, torsional spring 7 and rectangular sliding sash 8；Engaging sleeve is equipped with one on the center lead screw of the valve body 1
Locate handwheel 2, and handwheel 2 is rotatably dispose on circular rotatable seat, and symmetrical support downwards in the circumferential end surfaces of circular rotatable seat
It is welded with rotation seat fagging 3 at two；The connecting rod 6 is equipped with everywhere altogether, and connecting rod 6 is connected to by the head and the tail of attachment base everywhere everywhere
Diamond shape top bracing mechanism at one is formed together；4 screw thread of threaded rod is disposed through attachment base at two among connecting rod 6 everywhere
On；The attachment base of 6 bottom of connecting rod is directly welded in the bottom stage of left pivot movement seat stay plate 3 everywhere.
Wherein, the back-supported of the 6 top attachment base of connecting rod is provided with a prescription shape sliding sash 8 everywhere, this rectangular sliding sash 8
Sliding sleeve is set on the top section of left pivot movement seat stay plate 3, and rectangular sliding sash 8 can make the top attachment base of connecting rod 6 everywhere along left
Side rotation seat fagging 3 slides up and down straight, avoids the pressure on top surface mistake suffered by the attachment base of top when being shored of connecting rod 6 everywhere
It separates greatly to shift outward with left pivot movement seat stay plate 3 and attachment base at centre two fractures.
Wherein, supporting welding to the left has support shaft at one on the positive end face of the 6 top attachment base of connecting rod everywhere, and
Apical axis 5 with regard to turning set be set to this support shaft head end section on, rotary screwing thread bar 4 can make everywhere connecting rod 6 carry out rotation lifting shore,
Apical axis 5, which can carry out deflection with the tangential direction of the axial handwheel 2 of rising edge support of top attachment base, which to be shored, keeps handwheel 2 counterclockwise
Valve is shored release by rotation, and then is only needed rotary screwing thread bar 4 that can will shut and be difficult to open valve and put just efficiently open,
Using effect is preferable.
Wherein, the torsional spring 7 is sheathed in the support shaft of 6 top attachment base of connecting rod everywhere, and apical axis 5 by torsional spring 7 with
The connection of support shaft upper knob bullet, when connecting rod 6 everywhere rotates and declines, apical axis 5 can gradually glide from the fan groove of 2 bottom of handwheel
Extraction, torsional spring 7 can set right 5 knob of apical axis the initial support posture for being placed in and being slightly tilted at this time, and then follow apical axis 5
Lifting again for connecting rod 6 is inserted in again in the adjacent fan groove of rear side everywhere, is realized and is pushed up to the continuous rotation counterclockwise of handwheel 2
Support.
Wherein, circular array offers several place's fan grooves, and the head end of apical axis 5 on the bottom end face of the handwheel 2
Section is just inserted and is peaked in this fan groove, and it is the carrier that apical axis 5 shores force that fan groove can cooperate grafting to shore with apical axis 5.
The specifically used mode and effect of the present embodiment:
The process for using of the utility model, rotary screwing thread bar 4 clockwise first make everywhere connecting rod 6 carry out rotation shore, push up
Axis 5, which can carry out deflection with the tangential direction of the axial handwheel 2 of rising edge support of top attachment base, which to be shored, turns handwheel 2 counterclockwise
Dynamic that valve is shored releases, when apical axis 5, which deflects into, shores the limit, rotary screwing thread bar 4 counterclockwise declines the rotation of connecting rod 6 everywhere,
And apical axis 5 can gradually glide from the fan groove of 2 bottom of handwheel and extract out, 5 knob of apical axis can be set right and is placed in slightly by torsional spring 7 at this time
Inclined initial support posture (as shown in Figure 5), then again rotary screwing thread bar 4 clockwise can make apical axis 5 to handwheel 2 into
Row is shored again, and then is repeated the above steps continuously rotate counterclockwise handwheel 2 and be shored until valve movably screws
Operation.
The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustively or to incite somebody to action
The utility model is limited to disclosed form.Many modifications and variations are aobvious and easy for the ordinary skill in the art
