Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: exhaust apparatus, including exhaust pipe 1, and feature exists
In: one end of the exhaust pipe 1 is fixedly connected with rubber ring 2, and external screw thread 5,10 one end of vertical bar is arranged in the other end of the exhaust pipe 1
It is arranged in exhaust pipe 1, the other end of vertical bar 10 is connected with plectane 11, and rubber is arranged in the one side of the plectane 11 towards exhaust pipe 1
Cushion rubber 12, the vertical bar 10 pass through rubber ring 12, and the rubber ring 12 fits with plectane 11, the symmetrical two sides of the plectane 11
Affixed square bar 21,26 one end of spring are fixedly connected on the square bar 21, and the other end of two springs 26 is respectively and fixedly connected with
In the symmetrical two sides of annulus 14, spring 26 is the state that is stretched；The rubber ring 12 and rubber ring 2 match, rubber ring 12 to
Rubber ring 2 exerts a force, and mutual extrusion seals；The annulus 14 is sleeved on exhaust pipe 1 and is fixedly linked；The two of the annulus 14
Side is connected with first support 15, and the end of the first support 15 is rotatably connected to 17 one end of second support by pin shaft 16,
The other end of the second support 17 is connected with third bracket 18, and the end of the third bracket 18 is connected with round bar 19；It is described
The normally opened groove 23 and normally closed groove 22 matched with round bar 19 is arranged in 21 end of square bar；Normally opened groove 23 is towards first support
15, the direction of normally closed groove 22 is opposite with normally opened groove 23.
Symmetrical two springs 26 of exhaust apparatus, when the case where position limiting structure not using, itself has been stretched, spring
26 pulling force indirectly-acting is on rubber ring 12 and rubber ring 2, the two mutual extrusion, realizes sealing.Due to fully relying at this time
The pulling force of spring maintains sealing, when exhaust overpressure is excessive, can overcome the pulling force of spring, separate rubber ring 12 and rubber
Ring 2 prevents dangerous generation to realize exhaust.In addition can also manual lift-pull handle 13, actively separate rubber ring 12 and rubber
Rubber ring 2 realizes interim exhaust.
By first support 15, pin shaft 16, second support 17, the position limiting structure that third bracket 18 and round bar 19 form can be real
Now exhaust apparatus is normally opened or normally closed.The round bar 19 of position limiting structure can be stuck in normally opened groove 23 or normally closed groove 22.It is whole
The length of a position limiting structure is by design and calculates, and when being stuck in normally opened groove 23, is equivalent to position limiting structure and jacks up plectane 11,
The amplitude that spring 26 stretches becomes larger, and separates rubber ring 12 and rubber ring 2.At this point, exhaust apparatus maintains a normally open, gas freely into
Exhaust pipe.Pulling force is kept after being stretched due to spring, stable being stuck in normally opened groove 23 of round bar 19 will not fall off；When being stuck in
In normally closed groove 22, it is equivalent to position limiting structure and compresses plectane 11, the amplitude that spring 26 is stretched reduces, due to rubber ring 12 and rubber
Rubber ring 2 itself has elasticity, squeezes mutually more closely, and sealing is more preferable, and round bar 19 is stable is stuck in normally closed groove 22
It will not fall off.
Round bar 19 can either be stuck in normally closed groove 22 also can be in normally opened groove 23 because round bar according to pin shaft 16 with
The distance between normally opened groove 23, normally closed groove 22, the length of spring 26 and the diameter of round bar.The spring 26 of exhaust apparatus exists
Institute it is stateful it is next directly remain substantially stretched state, the only variation of stretch range.
When needing that exhaust apparatus is normally closed, the round bar 19 of position limiting structure all has bullet using rubber ring 12 and rubber ring 2
Property, apply the effect of external force to it, can be at a distance from moment diminution round bar 19 to be between normally closed groove 22,19 sets of round bar in side
It on bar 21 and sticks into the normally closed groove 22 matched with round bar 19, removes application external force later, rubber ring 12 and rubber ring 2 return
Bullet, the distance between round bar 19 and normally closed groove 22 have increase trend, to lock normally off, are become by spring driving sealing
Position limiting structure rigid seal will not be vented being vented overpressure and increasing.
Embodiment 2
Fig. 3-8 is please referred to, on the basis of embodiment 1, sliding slot 8, the sliding slot 8 are offered on 1 inner wall of exhaust pipe
Interior setting sliding block 9, the sliding block 9 are fixedly attached on one end of vertical bar 10 by cross bar 3, and sliding block 9 slides in sliding slot 8, limit
Vertical bar 10 processed is axially moved along exhaust pipe 1.
Sliding slot and sliding block are set, and the opening and closing of easy to exhaust guarantee that plectane 11 will not be extracted manually, fall off.And
And it is pre-designed the length of the axial upper hopper chute 8 of exhaust pipe 1, the maximum capacity of manually opened exhaust can be preset, and
When 1 internal gas pressure of exhaust pipe is excessive, the stroke length of plectane 11 is jacked up, realizes quantitative open.
In addition, the top center of plectane 11 is threaded with threaded rod 25, the top of the threaded rod 25 is connected with handle
13.In order to facilitate manual operation.
The outer wall of exhaust pipe 1 is socketed with the second rubber ring 7, the top of second rubber ring 7, bottom respectively with annulus
14, pipeline opening 6 fits.Increase the sealing effect between pipeline opening 6 and exhaust pipe 1.
When needing the structure for the pipeline opening 6 being vented not to be internal screw thread, the external screw thread 4 of exhaust pipe 1 replaces with and needs to control
The connection structure of 6 interface kit of pipeline opening of exhaust.
In the present invention unless specifically defined or limited otherwise, term " installation ", " setting ", " connection ",
The terms such as " fixation ", " being screwed on " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or at one
Body；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, can also indirectly connected through an intermediary, it can
To be the interaction relationship of connection or two elements inside two elements, unless otherwise restricted clearly, for this field
Those of ordinary skill for, can understand the concrete meaning of above-mentioned term in the present invention as the case may be.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
