Specific embodiment
With reference to the accompanying drawings and examples this utility model is described in detail.
As shown in figure 1, this utility model provides a kind of valve body 2 of pressure limiting valve, it is cylindrical hole in the middle of described valve body 2,
Stretch out in the middle part of described valve body 2 formation one annular boss 21, and valve body 2 is divided into valve body by the annular boss 21 on described valve body 2
Top 22 and valve body lower portion 23, described valve body lower portion 23 is provided with locking external screw thread 231, described valve body lower portion 23 bottom side
Offer first row pore 232, described valve body top 22 is located at and offers second row pore 222 above described annular boss 21.
Preferably, described valve body lower portion 23 bottom is fixed with peg 5, prevents it from dropping with the valve element 4 supporting shown valve inner.
As Figure 2-3, this utility model additionally provides a kind of pressure limiting valve, and it is mainly used in pressure cooker, is arranged on institute
State on pressure cooker lid.Described pressure limiting valve includes valve seat 1, valve body 2, nut 3, valve element 4, peg 5, pressure regulating cover 6 and spring 7, valve
Body 2 is valve body shown in Fig. 1；It is provided with locking female thread 31 in described nut 3, formed with the locking external screw thread 231 of described valve body 2
Tight lock construction, described nut 3 upper and lower offers several upper air-vents 32 and several lower steam vent 33 respectively, with described valve
The first row pore 232 of body 2 is corresponding；The bottom of described valve seat 1 extends inwardly to form an annular platform 11, described valve body top
22 and annular boss 21 be located in described valve seat 1, the annular boss 21 of described valve body 2 is set in the ring-shaped flat of described valve seat 1
On platform 11；Described valve element 4 is cylinder axis, and its cross section is t type structure, including valve element bottom 41 and valve element top 42, described valve
Core 4 is set in described valve body 2, and described spring 7 is set in described valve element top 42, and described valve element 4 can drive spring 7 described
Move up and down in valve body 2, the upper end of described spring 7 is contacted with described pressure regulating cover 6, described valve seat 1 is provided with and described
Corresponding 3rd steam vent 12 of two steam vent 222；It is provided between described valve seat 1 and pressure regulating cover 6 and drive described pressure regulating cover 6 lifting
Pressure regulating device.
Described pressure regulating device includes being arranged on the pressure regulation external screw thread 221 on described valve body top 22, is arranged on described pressure regulating cover 6
The pressure regulation female thread 61 of inner side, it is arranged on described valve seat 1 inner side and is located at the multistage gear bar 13 of described annular platform 11 top, sets
Put the gear block 62 in described pressure regulating cover 6 side.
Stair-stepping several gear platform 131 is provided with described multistage gear bar 13, each gear platform 131 can make described
