Outer wall is provided with external screw thread, and external screw thread is engaged with female thread.By screwed tight, valve casing 1 is rigidly secured to pressure release barrel 3
Interior.
The effect of tight mechanism is to increase the air-tightness of pressure relief device, so that all of air-flow is all arranged from pressure release aerofluxuss in the hole
Go out, it is to avoid air-flow produces noise through gap.
Tight mechanism includes pushing up the close structure of close structure and bottom：
Push up close structure, as shown in Fig. 6, Figure 10 and Figure 11, push up close structure and include pushing up close annular groove 33, push up close annular groove 33 and be opened in
Pressure release barrel 3 top, is provided with the close circle 41 in top, pushes up close annular groove 33 and be located at pressure release barrel 3 inwall, on valve casing 1 before the close annular groove in top 33 is interior
Be additionally provided with for fixing top Mi Quan in push up the fixing bulge loop 14 in close annular groove push up close enclose L-shaped, described valve casing top is provided with use
In the close caulking groove in top 16 being embedded top Mi Quan, valve casing top is additionally provided with the close pressure ring in top 17 of compression top Mi Quan.
As shown in Figure 3 or Figure 4, when valve casing 1 pushes, the close circle 41 in top is completely embedded in the close caulking groove 16 in top, top close circle 41 water
Flat part is compressed downwards by pushing up close pressure ring 17, plays good sealing function, makes level complete with the gap on vertical direction
Sealing, prevents gas from oozing out.
As shown in figure 11, the close circle in top 41 integral middles are provided with oblique ring 410, push up close pressure ring 17 and are provided with falling of compressing with oblique ring
Angle.Tiltedly the effect of ring 410 is to increase the integral thickness of the close circle 41 in top, and makes up the sealing deformation on level and vertical direction
Amount, when the chamfering pushing up close pressure ring 17 is pressed into oblique ring 410, oblique ring deforms, to vertically and horizontally deforming, will between
Gap is filled up.
The close structure in bottom, including the close circle 42 in bottom, bottom close circle 42 tapered ring-types, the close circle in bottom 42 is located at pressure release barrel 3 and valve
Between shell 1, valve casing 1 lower end compresses the close circle 42 in bottom, and in a tubular form, valve casing 1 lower end and the bottom Mi Quan place of compressing are provided with and bottom for valve casing 1 lower end
The sealing chamfering 15 of close circle taper fit.
The taper of the close circle 42 in bottom and sealing chamfering 15 coordinate, and can increase the area of sealing, improve sealing, and permissible
The horizontal and vertical equal sealing that can obtain is strengthened.
The bottom of the close circle 42 in bottom is additionally provided with horizontal washer 420, and the thickness of horizontal washer 420 is more than bottom close circle 42 thickness, water
Plain washer is integrally formed with bottom Mi Quan.Due to valve casing be threaded into tighten when, downward pressure is larger, sets up level pad successively
Circle 420 can effectively compress valve casing bottom, and more preferable utilization, the thickness of horizontal washer 420 are played in the effect of tightening to valve casing
Thicker, it is to deal with compressing when valve casing is tightened it is therefore desirable to thicker thickness is used for deformable seal.
It is provided with the closure gasket groove 34 being embedded for bottom Mi Quan, the close circle 42 in bottom and horizontal washer 420 are all embedded in pressure release barrel 3
In closure gasket groove 34, the tapered ring-type of closure gasket groove 34.
The effect of closure gasket groove 34 is when the close circle 42 in bottom and horizontal washer 420 are by valve casing crimp, can be complete
Full live whole closure gasket groove 34, make the area of contact bigger, effectively improve sealing property.Secondly, closure gasket groove 34 can
To play good fixation to bottom Mi Quan and horizontal washer, during preventing valve casing from turning, bottom Mi Quan and horizontal washer run
Partially.
Pressure release barrel 3 top is additionally provided with the close annular groove 33 in top, pushes up and is embedded with the close circle 41 in top, the close annular groove in top 33 in close annular groove 33
In pressure release barrel 3 inwall, valve casing 1 is additionally provided with the fixing bulge loop 14 in the close annular groove in top for fixing top Mi Quan.
In the present embodiment, there is the place in gap except bottom in valve casing and pressure release barrel, also top, therefore top remain unchanged
Need to set up sealing structure.
The close annular groove 33 in top is set up on the side wall of pressure release barrel, in the close annular groove in top 33, places the close circle 41 in top, the close circle 41 in top is
Usual endless bottom Mi Quan, when valve casing is tightened, the fixing bulge loop 14 of valve casing outer wall can be held out against pushing up close circle 33, prevents from pushing up
Close circle 33 comes off or offsets.
It is provided with the cavity volume 11 for valve element 2 reciprocal telescopic movement inside valve casing 1, spring and valve element 2 are respectively positioned in cavity volume 11, hold
Chamber 11 side wall is provided with the valve opening 10 connecting with gap 30, and cavity volume 11 inner wall surface is additionally provided with bulge loop 13.The effect of bulge loop 13 is,
Valve element, when by spring fight back original position, can play a spacing effect, prevent valve element abjection cavity volume, cause control valve to lose
Effect.
Valve element 2 includes lead 20, and lead 20 assumes a " convex " shape located at the top of valve element 2, valve element 2, sets in cavity volume 11
There is the gathering sill 110 embedding for lead 20, return unit is spring, and spring housing is located at lead 20 side wall.
Lead 20 has two functions：First, it is for keeping the direction when sliding for the valve element it is ensured that valve element being capable of edge
The axis direction of valve casing enters line slip, prevents from offseting, it is to avoid dislocation；Secondly, sheathed for spring, spring is played with a limit
Position effect, prevents spring from shifting in use.
Due to pressure release barrel 3 with valve casing 1 when docking, still there is many places gap, therefore pressure release barrel 3 and valve casing 1 it
Between be additionally provided with prevent gas leakage top close circle 41 and bottom close circle 42.At two the effect of sealing ring be that it is possible to coordinate pressure release barrel 3 with
Valve casing 1 tightens effect, by valve casing 1 push by sealing ring tightly card jail in gap, improve tightness, it is to avoid air-flow from
Overflow in gap, noise occurs.
It is more than preferred implementation of the present utility model, for the person of ordinary skill of the art without departing from this reality
On the premise of new principle, some modifications and improvement can also be made, these also should be regarded as protection domain of the present utility model.
