Specific embodiment
Hereafter by the drawings and specific embodiments, the utility model is described further.
Embodiment 1
With reference to Fig. 1-4, a kind of tuyere relief valve, including tuyere assembly 1 and pressure release valve module 2；
Described tuyere assembly 1 includes body 11 and lower body 12 on one；Described upper body 11 has tuyere 111, and
It is connected with the threaded one end of lower body 12；Having one in described upper body 11 allows bit port 112 and being surrounded on allow bit port 112
Outer containing groove 113；Described lower body 12 has an accommodating cavity 121, and the side wall of described lower body 12 has with bottom and connects
The passage 122 of accommodating cavity 121 and air chamber.
Described pressure release valve module 2 is installed in described accommodating cavity 121.Described pressure release valve module 2 includes valve seat 21, valve body 22
With core assembly 23；Be there is in described valve seat 21 cavity 211 being arranged in the same direction with described accommodating cavity 121.In the present embodiment, institute
The side position corresponding with described cavity 211 with bottom surface stating accommodating cavity 121 has and described connects the logical of accommodating cavity 121 and air chamber
Pore 122.
Cavity 211 top of described valve seat 21 extends a valve rod 212 away from the direction of described cavity 211；This valve rod
212 pass through described allow bit port 112 and tuyere spring 213, one end of described tuyere spring 213 is fixedly installed on described accommodating recessed
In groove 113, the other end is subject to the extruding of screw 214 and nut 215 to compress, and the elastic reset power of tuyere spring 213 makes spiral shell
Female 215 have the movement tendency above carrying, thus described valve seat 21 is above carried so that cavity 211 top of valve seat 21 with described on
Body 11 contact contacts；It is close that the part that cavity 211 top of described valve seat 21 is contacted with upper body 11 contact is provided with diaphragm seal 216
Envelope.
Because the sealing function of diaphragm seal 216 is so that passage 122 and tuyere 111 are separated by by the sealing of described diaphragm seal 216
From, it is achieved thereby that the sealing of air chamber.When air chamber being inflated or exits when needing, user applies downwards to nut 215
Pressure so that the overall contact matching relationship moving down, relieving valve seat 21 and upper body 11 of valve seat 21, passage
122 are connected such that it is able to chamber inflated by the gap between upper body 11 and valve seat 21 with tuyere 111, or to air chamber
Venting.It is achieved that normal charging-discharging function.
In the present embodiment, decompression function is realized by following structure：Described passage is passed through in one end of described cavity 211
122 are connected with air chamber, and the other end is provided with the relief hole 217 connecting with described tuyere 111；The inwall top edge of described cavity 211
Cavity 211 length direction shown in also has a limiting section, preferably thimble 218.
Described valve body 22 is arranged in described cavity 211 with core assembly 23.Described core assembly 23 includes valve element 231 He
Seal 232；Described valve body 22 includes a resigning hole 221, described seal 232 be arranged on valve element 231 and this resigning hole 221 it
Between；Valve element 23 and seal 232 in the presence of air chamber air pressure with valve body 22 contact so that seal 232 is by this resigning hole 221
Sealing, so that one end of described cavity 211 is separated by described valve body 22 and core assembly 23 with the other end.So that valve
Body 22 and core assembly 23 form a sealing with valve seat 21.
When the air pressure in described air chamber increases, described valve body 22 and core assembly 23 are under the influence of air pressure towards close
The direction of described thimble 218 is moved；When the air pressure in described air chamber reaches pressure release value, described thimble 218 is by described resigning
Hole 221 and described seal 232 contact；When the air pressure in described air chamber is higher than pressure release value, valve body 22 continues to move to, and valve element
Assembly 23 stop motion by the spacing of described thimble 218, so that core assembly 23 is separated with valve body 22, described relief hole
217 connection air chambers form pressure release passage makes the gas in air chamber discharge.Thus having reached self-relieving purpose.Due to pressure release
In journey, core assembly 23 is spacing by thimble 218 contact all the time, core assembly 23 in the presence of air-flow also will not bob, make
The service life obtaining core assembly 23 has obtained effective lengthening.
In the present embodiment, in the cavity 211 of described valve seat 21, it is additionally provided with valve body spring 219, its one end and cavity 211 inwall
Top contact, the other end and described valve body 22 contact；When the air pressure in described air chamber is less than pressure release value, this valve body spring 219
Elastic force make valve body 22 and core assembly 23 away from described thimble 218.
Described core assembly 23 also includes a valve core spring 233, and its one end is fixedly connected with valve body 22, the other end and valve element
231 and seal 232 contact；When described thimble 218 is spacing with seal 232 contact, described valve core spring 233 is compressed；
When the air pressure of described air chamber is less than pressure release value, described valve body 22 resets in the presence of valve body spring 219, so that described
Described resigning hole 221 is sealed valve core spring 233 by reset strap dynamic seal 232 again therewith.It is achieved that after pressure release from
Dynamic sealing.
Therefore, when the air pressure in air chamber is less than pressure release value, core assembly 23 relies on valve core spring 233 and air chamber air pressure
Seal 232 and resigning hole 221 contact are sealed by collective effect, and sealing effectiveness is relatively good.Let out when the atmospheric pressure value in air chamber is more than
During pressure value, the elastic force of valve core spring 233 is less, therefore can realize opening rapidly of seal 232, pressure release is timely.And, work as
When atmospheric pressure value in air chamber drops to less than pressure release value, because the elastic force of valve core spring 233 is much smaller than the bullet of valve body spring 219
Power, therefore, valve core spring 233 can reset rapidly in the presence of valve body spring 219, quickly stops pressure release.Ensure that air chamber
Interior gas will not excessive leakage.
In the present embodiment, also include a tuyere lid 3, it inserts in described tuyere 111；It is provided with described tuyere lid 3 and give vent to anger
Hole 31, it is connected with described relief hole 217 by the bit port 112 that allows of upper body 11.Gas from relief hole 217 outflow after, from
Described venthole 31 is discharged.
With reference to Fig. 5, in the present embodiment, the inwall of described air chamber or outer wall 4 extruding are arranged at body 11 and lower body 12
Between, and rely on the extruding force between described upper body 11 and lower body 12 to seal with upper body 11 and lower body 12 respectively.
It should be noted that limiting section is the top in cavity inner wall for the Position Design of thimble 218 in the present embodiment, according to
It is actually needed, this thimble can also design in other positions, as long as being capable of when air pressure increases, this limiting section is by valve element group
Sealing relationship between part and valve body releases.As Fig. 6, shown.
