On spacing ring 7, fixed part 8；A mounting groove 10 is provided with the valve body 1, non-return valve core 6 is located at peace close to one end of water inlet 2
In tankage 10；The mounting groove 10 is provided with a through hole 11 connected with water inlet 2；It is provided with the non-return valve core 6 with going out
The relief hole 12 that the mouth of a river 3 connects；It is more than the mounting hole 13 of relief hole 12, mounting hole in the non-return valve core 6 provided with an aperture
13 are connected by through hole 11 with water inlet 2, and mounting hole 13 connects with relief hole 12；One is provided with the mounting hole 13 to let out
Pressure valve core 14；The head of pressure releasing valve core 14 is in umbrella, and the head of pressure releasing valve core 14 blocks relief hole 12, makes relief hole 12 and peace
Fill the not insertion of hole 13；A pressure release spring 15 is arranged with outside the pressure releasing valve core 14；Described one end of pressure release spring 15 is connected to pressure release
On valve element 14, the other end is contradicted on cell wall of the mounting groove 10 provided with through hole 11.
The outer wall of non-return valve core 6 extends outward the sealing 16 that an aperture is less than spacing ring 7, and sealing 16 is located at limit
The position lower surface of ring 7；The sealing 16 is mutually closed with sealing hole 5.
The sealing 16 is provided with annular groove 17, annular groove 17 and is provided with sealing ring 18.
The head of pressure releasing valve core 14 is provided with a caulking groove 19；The sealing shroud matched with it is installed on the caulking groove 19
20, sealing shroud 20 is in umbrella；The sealing shroud 20 blocks relief hole 12, makes relief hole 12 and the not insertion of mounting hole 13.
The sealing shroud 20 is quality of rubber materials.
The head outer wall of pressure releasing valve core 14 extends outward an annular protrusion 21；The two ends of pressure release spring 15 are supported respectively
Touch on annular protrusion 21, the cell wall of mounting groove 10.
Application method of the present utility model is as follows：
First pressure release check-valves is installed in actually required equipment, external pipeline is then connected to pressure release check-valves
At water inlet 2, it can then enable flow through in the equipment needed for external pipeline is delivered to, when fluid is flowed at water inlet 2
When, fluid can form pressure, and non-return valve core 6 is extruded, and non-return valve core 6 is moved towards the direction of delivery port 3, check spring
9 are compressed, and spacing ring 7 slowly departs from limited step 4, and sealing hole 5 is no longer on sealing state, and fluid will can then pass through sealing
Hole 5 is flowed into the runner of valve body 1, finally from delivery port 3 is flowed into actually required equipment.
When fluid is constantly conveyed towards delivery port 3, because direction and the pressure releasing valve core 14 of flow of fluid are by relief hole 12
The direction for blocking the pressure formed is consistent, therefore the flowing of fluid will not have any impact to pressure releasing valve core 14, fluid to
In the course of conveying of delivery port 3, pressure releasing valve core 14 all the time blocks relief hole 12.
Excessive pressure difference is produced the problem of duct height and temperature change, the fluid entered in equipment will start back
Stream, is entered in valve body 1 by delivery port 3, and the fluid of this burst backflow can be equally extruded non-return valve core 6, compressed
Check spring 9 can be equally extruded non-return valve core 6 by its own resilient, non-return valve core 6 is moved towards water inlet direction,
Now spacing ring 7 can then be fitted on limited step 4 again, and sealing hole 5 is covered, and sealing hole 5 is not circulated, fluid can not
Water inlet 2 is back to by sealing hole 5.
In fluid reflux, fluid can then be come in contact by the head of relief hole 12 and pressure releasing valve core 14, and fluid passes through
Pressure itself is promoted to pressure releasing valve core 14, pressure releasing valve core 14 is moved towards the direction of water inlet 2, now the quilt of pressure release spring 15
Compression, when the head of pressure releasing valve core 14 departs from relief hole 12 gradually, relief hole 12 is changed into insertion each other again with mounting hole 13
State, fluid can be then entered in mounting hole 13 by relief hole 12, and water inlet 2 is entered finally by through hole 11, allow backflow
Pressure and the pressure balance of water inlet 2, realize the effect of pressure release.
And the normal setting pressure of fluid sets pressure then equivalent to the elastic force of pressure release spring 15 when return pressure is less than
When, pressure release spring 15 resets pressure releasing valve core 14 by its own resilient, and pressure releasing valve core 14 is again by pressure release hole plug, and fluid can not
Pressure release is carried out by relief hole 12 again, it is to avoid fluid situation about flowing back occurs in the case of pressure is normal by relief hole 12.
Understand in summary, the utility model can be by non-return valve core 6 and pressure releasing valve core 14, while realizing non-return and pressure release
Effect, the function of non-return is played when Fluid pressure is normal, the function of pressure release can be then played when Fluid pressure is excessive, it is to avoid
Pipeline causes the situation of explosion because pressure difference is excessive, has prevented unexpected generation, more can be automatic to close when Fluid pressure is normal
Decompression function, prevents fluid from situation about flowing back occur by pressure release passage.
The outer wall of non-return valve core 6 extends outward the sealing 16 that aperture is less than spacing ring, and sealing 16 is located under spacing ring 7
Surface, sealing 16 is mutually closed with sealing hole 5, and the presence of sealing 16 can further improve non-return valve core 6 and sealing hole 5 is close
Sealing during envelope, and sealing 16 is provided with annular groove 17, is provided with sealing ring 18 in annular groove 17, sealing ring 18
In the presence of the sealing between sealing 16 and sealing hole 5 can be ensured to the full extent, the feelings of fluid reflux infiltration are prevented
Condition, improves performance.
The head of pressure releasing valve core 14 is provided with caulking groove 19, caulking groove 19 and is provided with the sealing shroud 20 matched with it, sealing shroud 20
In umbrella, sealing shroud 20 blocks relief hole 12, makes relief hole 12 and the not insertion of mounting hole 13, sealing shroud 20 and pressure releasing valve core 14
And it is non-integral, when sealing shroud 20 is damaged, sealing shroud 20 only need to be changed, maintenance cost is reduced and reduces maintenance work
Amount, and sealing shroud 20 is quality of rubber materials, can not only strengthen sealing shroud 20 by the material characteristic of the rubber blocks relief hole 12
When sealing, dismounting sealing shroud 20 when then seem more convenient, only need to apply external force just can be by sealing shroud 20 out of caulking groove 19
Take out or be embedded into caulking groove 19.
The head outer wall of pressure releasing valve core 14 extends outward annular protrusion 21, and the two ends of pressure release spring 15 are contradicted in convex annular respectively
Rise on the 21, cell wall of mounting groove 10, this structure enables pressure release spring 15 arbitrarily to be taken out from pressure releasing valve core 14, beneficial to positive normal pressure
The setting of power, can select the pressure release spring 15 of corresponding elastic force according to actually required Fluid pressure.
