Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
Field technique personnel can make to the present embodiment after reading this specification as needed does not have the modification of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
Embodiment 1：A kind of pressure-regulating valve, as depicted in figs. 1 and 2, including the valve body 3 being provided with air vent 1, air vent
1 one end being located at valve body 3, the other end of valve body 3 is arranged with bonnet 2, spiral shell between the lateral wall of the medial wall of bonnet 2 and valve body 3
Stricture of vagina connects, and in valve body 3, level is provided through valve element 4, valve element 4 be shaped as cylinder, the threaded one end of valve element 4 is connected with row
The valve head 5 that QI KOU 1 matches, air vent 1 is blocked by valve head 5, and the other end of valve element 4 stretches out in bonnet 2, the excircle of valve element 4
On the wall of side, depression is formed with the annular groove 8 of annular, annular groove 8 and installs the barrier ring 7 being placed with annular, the internal ring wall of barrier ring 7 with
The inwall laminating of annular groove 8, the external annulus of barrier ring 7 are fitted with the inwall of valve body 3, thus the inside of valve body 3 is separated into 2 phases
The space of isolation, on valve element 4, level is arranged with spring 6, the two ends of spring 6 respectively with the side ring wall of barrier ring 7, bonnet 2
Inwall abuts against, and during use, rotates bonnet 2, valve head 5 moves right, and produces certain gap between valve head 5 and air vent 1, pressure
Power and steam enter in valve body 3 by this gap, and barrier ring 7 is lived to the steam barrier entering in valve body 3, now, steam
Positioned at the left side of barrier ring 7, spring 6 is located at the right side of barrier ring 7, is separated steam with spring 6 by barrier ring 7, it is to avoid steam
Contact between vapour and spring 6, thus decreasing the damage that steam causes to spring 6；
Barrier ring 7 is rubber ring, and rubber ring is made up of elastomeric material, has certain wearability, the external annulus of rubber ring with
The abrasion producing during valve body 3 contact internal walls is smaller, barrier ring 7 sliding in valve body 3 can be avoided to produce abrasion, ensured barrier
Ring 7 completely cuts off the performance of steam and spring 6, plays preferably isolation performance.
As depicted in figs. 1 and 2, the side wall of valve body 3 offers the steam vent 9 running through inside and outside valve body 3, bonnet 2 is enclosed within valve
Body 3 is in and does not start under rotation status, and steam vent 9 is relative near one end inwall of valve head 5 with bonnet 2, rotates bonnet 2, bonnet 2
Move right, steam vent 9 being exposed to outside valve body 3 gradually, valve element 4 is pushed by pressure pot inner pressure, moves right, barrier ring 7
With the mobile right side to steam vent 9 of valve element 4, now, steam vent 9 is connected with the space in barrier ring 7 left side, the steam in this space
Discharge from steam vent 9, by the setting of steam vent 9, so that the steam in entrance all valve bodies 3 can be timely discharged, from
And reduce the damage that steam causes to valve body 3, improve the service life of this pressure-regulating valve.
As shown in figure 1, being provided with wing plate 13 on the lateral wall of bonnet 2, wing plate 13 is located at bonnet 2 near one end of valve head 5,
And wing plate 13 is formed along extending radially outwards of bonnet 2, in the present embodiment, wing plate 13 cincture on the lateral wall of bonnet 2
One circle, when rotation bonnet 2 makes steam vent 9 expose, steam is discharged from steam vent 9, because the temperature of steam is higher, easily contacts
Rotate the finger of bonnet 2 to user, thus causing the scald of user finger, therefore, setting on bonnet 2 stretches out
Wing plate 13, the steam discharged from steam vent 9 by wing plate 13 barrier and the finger of user, make the steam will not be to user finger
Direction flowing, thus improve this pressure-regulating valve use safety, hommization.
Mounting ring 10, the circle being shaped as concentric of mounting ring 10 and steam vent 9 are removably connected with steam vent 9 inwall
Shape, in the present embodiment, the mode that is detachably connected is clamping, is provided with and protrudes from external annulus on the external annulus of mounting ring 10
Elastic bumps 12, are provided with the buckling groove being engaged by clamping with elastic bumps 12, by elastic bumps 12 on the inwall of steam vent 9
With the clamping engagement of buckling groove, mounting ring 10 is made to be detachably secured in steam vent 9, during dismounting, by instrument to mounting ring 10
One along the power on steam vent 9 axis direction, elastic bumps 12 is departed from buckling groove and is engaged by clamping so that mounting ring 10 from
Spin off in steam vent 9, during installation, promote mounting ring 10 sliding in steam vent 9 by instrument, make elastic bumps 12 clamping
To in buckling groove, so that mounting ring 10 is fixed in steam vent 9；Mounting ring 10 is provided with for filtering in steam
The drainage screen 11 of oil, drainage screen 11 is bonded on the internal ring wall of mounting ring 10, can mix from the steam that steam vent 9 discharges
There is oil, the oil smoke in kitchen can be caused with steam together discharge heavier, the health of human body is caused to damage, therefore, in peace
On dress ring 10, drainage screen 11 is set, will be filtered down by the oil that steam vent 9 discharges, reduce the generation of oil in kitchen,
Improve the use environment of people；During using needing to change drainage screen 11 after a period of time, mounting ring 10 being disassembled, replaces with
New mounting ring 10 and drainage screen 11, so that drainage screen 11 can play preferable strainability.
Embodiment 2：A kind of pressure-regulating valve, difference from Example 1 is, steam vent 9 inwall and mounting ring 10 can
It is threaded that dismounting is fixedly connected mode, arranges external screw thread on the external annulus of mounting ring 10, arranges on steam vent 9 inwall
There is the female thread with the cooperation of external screw thread screw thread, coordinated by internal and external threads, mounting ring 10 is threadedly secured in steam vent 9, need
During drainage screen 11 in mounting ring 10 to be changed and mounting ring 10, by rotating mounting ring 10, by mounting ring 10 from steam vent 9
Inside disassemble, realize replacing action, during installation, by reversely rotating mounting ring 10, by mounting ring 10 and mounting ring 10
