Valve element, one end of valve element is through in hole, the other end contradicted in the presence of spring and valve core housing air admission hole realize seal, when
When valve core housing and valve element are moved upwards, valve element departs from air admission hole to be contradicted, and air admission hole is communicated with steam vent.
Preferably, an end face of valve core housing is provided with deep gouge, valve element includes axial columnar part, the first protuberance, second
Protuberance, wherein axial columnar part, the second protuberance are corresponded to positioned at the upper side and lower side of the first protuberance respectively.Axial columnar part
Coordinate with hole, the first protuberance coordinates with deep gouge, the second protuberance coordinates with air admission hole, can make between valve element and valve core housing
Better tightness, and valve core housing play the guiding role to valve core movement.
Preferably, bonnet and matching somebody with somebody for valve body are combined into screw thread cooperation, it can adjust pressure cooker pot inner pressure, and screw thread is matched somebody with somebody
Close stability strong.
Preferably, the second protuberance of valve element is spherical or taper, it can have the cooperation of valve element and air admission hole
Better seal, and pot inner pressure change can more rapidly be made a response.The material of selected valve element is plastics, quality
It is lighter, and processing is simple, cost is low, it is easy to clean.
Sealing ring is housed preferably, being equipped between described valve core housing and valve body on sealing ring, the first protuberance, can be made
Sealing increase, makes steam not polluted into valve pocket to valve pocket inside between part.
The utility model is as a result of above technical scheme, with significant technique effect：
Pressure limiting valve is readily cleaned the utility model in use, and the utility model pressure limiting is sensitive, and sealing is strong,
The accidents such as exhaust hole plug are not likely to produce, the utility model is simple and reasonable in addition, and valve element is with low cost, and replacement cost is low.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
High-pressure cooker pressure limiting valve, as shown in Figures 1 to 4, including bonnet 1, spring 2, valve body 3, valve core housing 4, wherein valve element 5, valve
Cap 1 coordinates with valve body 3, and the middle part of valve body 3 is provided with valve pocket 31, and the lower surface of valve body 3 is provided with air admission hole 32, and the side of valve body 3 is provided with
Steam vent 33, spring 2 is placed in valve pocket 31, and the one end of spring 2 and the top of bonnet 1 are inconsistent, the other end and the upper end of valve core housing 4
Face is inconsistent, and valve core housing 4 coordinates with valve pocket 31, and sealing ring is housed between valve core housing 4 and valve pocket 31, makes valve core housing 4 and valve pocket 31
Side wall sealing.Be provided with hole 41 on valve core housing 4, the lower surface of valve core housing 4 is provided with deep gouge 42, valve element 5 include axial columnar part 51,
First protuberance 52, the second protuberance 53, wherein axial columnar part 51 is assigned into inside hole 41, in the presence of spring 2, first
Protuberance 52 coordinates with deep gouge 42, due to being equipped with sealing ring on the first protuberance 52, coordinates so valve element 5 is sealed with valve core housing 4.
Second protuberance 53 is contradicted into air admission hole 32, is made in valve with being isolated in pot.When air pressure is more than the pressure of spring 2 in pot,
Valve element 5 drives valve core housing 4, and motion makes the second protuberance 53 with air admission hole 32 depart to coordinate upwards, and excessive gas is from steam vent 33
Discharge.
Pressure limiting valve is before work, and downward turn bonnet 1 makes the 3rd nose section 53 of valve element 5 be fitted close with air admission hole 32,
When pot inner pressure is more than the pressure of spring, the gas push valve element 5 in air admission hole 32 departs from the contact with air admission hole 32, now
Air admission hole 32 is connected with steam vent 33, so that excessive gas is discharged, after gas discharge pressure recovers, valve element 5 is in spring 2
In the presence of again to air admission hole seal.Rotating bonnet 1 makes it control the decrement of spring 2 in different positions with this, from
And the pressure in pressure cooker can be controlled.
High-pressure cooker pressure limiting valve can also realize discouraged function, be rotated up bonnet 1, so that spring 2 is lost on valve core housing 4
Active force, gas need to only overcome the gravity of valve core housing 4 and valve element 5 to realize that degassing function valve element 5 is plastic material, shaping
Simpler, quality lighter, price is low, good sealing effect, can also make discouraged more thorough.
In the present embodiment, the 3rd nose section 53 of valve element 5 is shaped as hemispherical or taper, thus improve valve element 5 with
The sealing of air admission hole 32, and pressure limiting valve reaction can be made sensitiveer.
Embodiment 2
The present embodiment difference from Example 1 is, as shown in figure 5, the number of described steam vent 33 is 4, and
It is uniformly distributed, so that exhaust is rapider, also reduces because the safety that blocks and bring of steam vent 33 is hidden along the outer surface of valve body 4
Suffer from.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute
The equivalent changes and modifications of work, should all belong to the covering scope of the utility model patent.
