Layer inner wall bottom be equipped with the corresponding gas vent of the venthole, between the concentric double-tube funnel bottom and the exhaust pipe
It is connected with adjusting limit spring.
Further：It is described to adjust limit spring to stretch adjusting limit spring, and the adjusting limit spring that stretches is
The stainless steel stretched adjusting limit spring of alramenting.
Further：The adjusting limit spring is connected with one end that the exhaust pipe is connected by adjusting screw.
Further：Several ventholes are several ventilation circular holes by diameter arrangement.
Further：Sealing ring is equipped between the concentric double-tube funnel bottom and the exhaust tube outer surface, it is described close
Seal is rubber seal.
Further：The concentric double-tube funnel oral area is equipped with seal washer.
The utility model has the advantages that：
1st, flow position adjustable gas release provided by the utility model passes through concentric double-tube funnel bottom and institute
It states to be connected between exhaust pipe and adjusts limit spring adjusting position, and equipped with several ventilation circular holes by diameter arrangement, row
Gas flow in process, position-adjustable.
, flow position adjustable gas release provided by the utility model adjusting limit spring for stretch adjust limit
Position spring, and described stretch adjusts limit spring as the stainless steel stretched adjusting limit spring of alramenting, tensile strength is big, is not easy
It is corroded, use feeling long lifespan.
, flow position adjustable gas release provided by the utility model adjusting limit spring and the exhaust pipe
Connected one end is connected by adjusting screw, by the level of stretch of the elastic change spring of adjusting screw so as to controlling gas
The position of release, it is easy to operate.
, flow position adjustable gas release provided by the utility model concentric double-tube funnel bottom and the row
Rubber seal is equipped between tracheae outer surface, the concentric double-tube funnel oral area is equipped with seal washer, effectively prevents gas from letting out
Dew, leakproofness are strong.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and embodiments：
Fig. 1 is the axial section of flow position adjustable gas release；
Fig. 2 is vent hole structure schematic diagram；
Wherein：1st, gas alarm is popped one's head in；2nd, exhaust pipe；3rd, concentric double-tube funnel；4th, interlayer；5th, venthole；6th, gas vent；

Specific embodiment
Embodiment：A kind of flow position adjustable gas release as shown in Figure 1, including exhaust pipe 2 and for
The concentric double-tube funnel 3 of 1 docking of gas alarm probe, 2 tube wall of exhaust pipe are slidedly arranged on 3 neck of concentric double-tube funnel
In the interlayer 4 that inside and outside wall is formed, and 2 outer surface of tube wall of the exhaust pipe is close to 4 inner surface of interlayer, the exhaust
2 outer surface of pipe is mutually close to the concentric 3 neck inner wall of double-tube funnel, and the 2 tube wall upper end of exhaust pipe is equipped with several ventholes
5, the 4 inner wall bottom of interlayer is equipped with and the 5 corresponding gas vent 6 of venthole, concentric 3 bottom of double-tube funnel and institute
It states to be connected between exhaust pipe 2 and adjusts limit spring 7, the adjusting limit spring 7 adjusts limit spring to stretch, and the drawing
It stretches and adjusts limit spring as the stainless steel stretched adjusting limit spring of alramenting.The adjusting limit spring 7 and the exhaust pipe 2
Connected one end is connected by adjusting screw 8.
Several ventholes 5 are 4 ventilation circular holes 11 by diameter arrangement.
