Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
As shown in the picture, the utility model includes valve body 1, flap 2, guide rod 3, spring 4, valve seat 5 and a pair of of sealing ring 6,
It is provided with ladder-like valve seat mounting groove on the gas outlet of valve body 1, is provided on the first order mesa sidewall of ladder-like valve seat mounting groove interior
Have sealing ring mounting groove at the top of one end of screw thread, the second level the bottom of the steps of ladder-like valve seat mounting groove and valve seat 5, one
Sealing ring 6 is separately mounted in corresponding slot, the valve seat 5 for being provided with sealing ring mounting groove one end is equipped with mounting disc, and is pacifying
The external screw thread being used cooperatively with ladder-like valve seat mounting groove is provided in sabot, the other end bottom of valve seat 5 is equipped with a circle and valve body 1
The briquetting that upper seal mounting groove is used cooperatively, valve seat 5 are screwed on the gas outlet of valve body 1, are equipped with and are led in the air inlet of valve body 1
Set 7 has guide rod pilot hole at the center of guide sleeve 7 and valve seat 5, and is provided with using guide rod pilot hole as center annular array more
A corresponding air-flow through hole, flap 2 are back taper tubular, and the flap 2 positioned at larger diameter end is opening, are located at small diameter
It is provided with guide rod installing hole on the flap 2 at end, is provided with multiple gas by center annular array of guide rod installing hole on the side wall of flap 2
Hole, flap 2 are fixedly mounted on guide rod 3, and 3 both ends of guide rod are located in the guide rod pilot hole of corresponding guide sleeve 7 and valve seat 5,
4 sets of spring on guide rod 3, and the both ends of spring 4 are connect with valve seat 5 and flap 2 respectively.
Guide sleeve 7 and valve body 1 are integrated casting and forming, and the guide sleeve 7 of one end is equipped with flap positive stop lug boss 8 in valve body 1.
Flap 2 is whole line with rubber flap.
Multiple air slots are provided on 1 inner wall of valve body between valve seat 5 and guide sleeve 7.
Working method and principle: the gas outlet of valve body 1 and the air inlet of exhaust valve communicate, and trimmer valve is located at exhaust valve and pipe
Between road, when needing to be vented, the flap 2 of the high pressure draught damping of shocks valve first in pipeline, flap 2 is raised above,
The reaction force of spring 4 plays buffer function, is closed flap 2 slowly, and valve seat 5 and guide sleeve 7 play guiding role to guide rod 3,
Flap 2 is set to keep stablizing, one group stomata of the air-flow on the gap and flap 2 between flap 2 and valve body 1 passes through, and enters back into
Into exhaust valve, reduce air-flow to the moment impact of exhaust valve, after high pressure draught is steady, flap 2 delays under the action of spring 4
Slow to reset, the air slot in valve body 1 is played to air-flow guiding function, is avoided air-flow from generating sinuous flow abrasion flap 2 in valve body 1, is led
Set 7 and valve body 1 are integrated casting and forming, reduce processing cost, and flap 2 is whole line with rubber flap, avoid gas medium to valve plate 2
Corroded, while preventing collision deformation, be connected through a screw thread between valve seat 5 and valve body 1, between valve seat 5 and valve body 1 and valve
It is all sealed by sealing ring 6 between seat 5 and exhaust valve, sealing effect is good, while making the threaded connection place of valve seat 5 and valve body 1
It will not be contacted with the gas medium in valve body 1, prevent from corroding screw thread rear valve base 5 because of gas medium and valve body 1 is difficult to open.
