Support is connect with valve body, and the top of the valve body is connected with rubber stopper, and the bottom of bracket passes through supporting rack and valve by bracket
Body bottom connects, and protective cradle is welded at the inside center of described sleeve pipe.
As further describing for above-mentioned technical proposal：
There are four the protective cradle welds altogether, and four protective cradles are angularly distributed in a ring along the inside of casing.
As further describing for above-mentioned technical proposal：
The internal diameter of the air inlet tube and vent connection is equal, and air inlet tube and vent connection are located at same horizontal line
On.
As further describing for above-mentioned technical proposal：
The air inlet tube is located at valve body in same horizontal line.
As further describing for above-mentioned technical proposal：
Support frame as described above is connected with eight altogether, and eight supporting racks circularize array distribution along on the outside of valve body.
In the utility model, first by being equipped with protective cradle, protective cradle can prevent spring bracing deformation quantity mistake
Greatly, it is damaged so as to cause spring bracing, spring bracing is protected, extends the service life of the spring bracing, from
And the quality of the new casing level pressure air-bleed valve gear is improved, secondly, by being equipped with connecting stud, regulation stud pair can be passed through
The support pressure of spring bracing is changed, so as to change the pressure value of the new casing level pressure air-bleed valve gear so that should
New casing level pressure air-bleed valve gear is more convenient to use, enhances the practicability of the new casing level pressure air-bleed valve gear.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-3, a kind of new casing level pressure air-bleed valve gear, including casing 4, the both ends of casing 4 are respectively by solid
Determine 7 spiral of nut and be socketed with vent connection 1 and air inlet tube 6, one end that casing 4 is internally located at vent connection 1 is welded with support
Frame 2 is connected with connecting bracket 14, and rotation is socketed in regulation stud 12 at 2 inside center of supporting rack by regulation stud 12
The adjusting nut 13 that regulation stud 12 uses, connecting bracket 14 are connect by spring bracing 3 with valve body 5, and the top of valve body 5 leads to
It crosses bracket 10 and is connected with rubber stopper 11, and the bottom of bracket 10 is connect by supporting rack 9 with 5 bottom of valve body, in the inside of casing 4
Protective cradle 8 is welded at the heart.
There are four protective cradle 8 welds altogether, and four protective cradles 8 are angularly distributed in a ring along the inside of casing 4, into
