Description
Technical field
The present invention relates to gas fire extinguisher check valve technical field, specially a kind of dedicated noise reduction of gas fire extinguisher is unidirectional
Valve.
Background technique
Check valve is also known as check-valves or non-return valve, be gas can only along air inlet flow into gas outlet flow out, and cannot from go out
Port flows into the device of air inlet outflow, is usually used in preventing gas reverse flow in fire extinguisher system, protects equipment safety, prevents
Maloperation, existing fire extinguisher is mostly gas fire extinguisher in the market, and squeeze grip is needed when encountering fire, and gas passes through unidirectional
Valve sprays out, gas is under pressure spray out during can generate biggish noise, and the spy used between fire extinguisher
Different property, the mood swing of people is larger when a fire, is easy to be influenced by extraneous factor, and hasty middle fire extinguisher of opening generates
Noise user can be caused to frighten, cause improper use to accidentally injure oneself, therefore a kind of novel fire extinguisher noise reduction check valve
It comes into being.
Summary of the invention
For the purpose for realizing above-mentioned check valve noise reduction, the invention provides the following technical scheme: a kind of gas fire extinguisher is dedicated

Valve seat, the side of valve seat are fixedly connected with spool, the right side of the valve seat and are located above spool and are fixedly connected with longitudinal gas
Flowing plate is fixedly connected with crossflow plate on the right side of longitudinal air flow plate, and the top of crossflow plate is fixedly connected with cylinder, described
Cabinet is fixedly connected with below crossflow plate, the internal activity of cabinet is connected with portable pillar, and the surface of portable pillar is socketed with
Spring, offers plenum duct on the left of the spool, and the junction of the valve seat and spool offers air inlet, the cylinder
Lower part and be located at crossflow plate top offer exhaust outlet.
The beneficial effects of the present invention are: gas moment reaches in exhaust passage, the air-flow of generation by artificial squeeze grip
Spool is pushed, and is flowed into from air inlet, gas shock longitudinal air flow plate changes direction and moves upwards, by crossflow plate and cylinder
Body is flowed out from exhaust outlet, in the process, because the direction of airflow plate destroys the Primordial Qi flow path at the gas whistle, is formed expanding and is disappeared
Sound device structure, to achieve the effect that effectively to eliminate pneumatic noise, and structure is simple, because being provided with bullet on the right side of spool
Spring, the air blast that gas flowing generates are pushed open, and air-flow disappearance spring reset reaches the effect that gas unidirectional flows in fire extinguisher
Fruit.
Preferably, the spool includes support plate, and plug is connected on the right side of support plate, and the side activity of plug connects
It is connected to sealing plate.
Preferably, the enclosure space that the cylinder and airflow plate are constituted is airflow channel.
Preferably, the internal diameter of the longitudinal air flow plate is greater than the internal diameter of crossflow plate, and the internal diameter of longitudinal air flow plate is horizontal
To times of airflow plate internal diameter, the internal diameter of longitudinal air flow plate might be less that the internal diameter of crossflow plate, become as long as forming diameter
Change, may be constructed expansion muffler structure to realize the decrease or elimination of noise.
Preferably, the rear end of the valve seat of the intracorporal spool of valve compression fit facing forward.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, a kind of dedicated noise reduction check valve of gas fire extinguisher, including exhaust passage 1, exhaust passage 1 it is interior
Portion is fixedly installed with valve body 2, and the rear end of the valve seat 3 of the compression fit facing forward of spool 4 in valve body 2, the inside of valve body 2 is fixedly connected
There is valve seat 3, the side of valve seat 3 is fixedly connected with spool 4, and spool 4 includes support plate 401, and the right side of support plate 401 is flexibly connected
There is plug 402, the side of plug 402 is connected with sealing plate 403, the fixed company in the right side of valve seat 3 and the top for being located at spool 4
It is connected to longitudinal air flow plate 5, the internal diameter of longitudinal air flow plate 5 is greater than the internal diameter of crossflow plate 6, and the internal diameter of longitudinal air flow plate 5 is horizontal
To 1.5 times of 6 internal diameter of airflow plate, the internal diameter of longitudinal air flow plate 5 might be less that the internal diameter of crossflow plate 6, as long as being formed straight
Diameter variation may be constructed expansion muffler structure to realize the decrease or elimination of noise, and expansion muffler also known as expands
Formula silencer is connected with connecting leg by each expansion chambers and is formed.It is to cause sound wave using expansion, the contraction of area of section
What reflection was eliminated the noise with interference.Its acoustic attenuation performance depends primarily on the divergence ratio and length of expansion chambers, longitudinal air flow plate 5
Right side is fixedly connected with crossflow plate 6, and air inlet 12 is open simultaneously to be flowed into cylinder 7, gas shock longitudinal plate airflow plate 5 and to
Upper flowing is flowed out through cylinder 7 and crossflow plate 6 through exhaust outlet 13, and the top of crossflow plate 6 is fixedly connected with cylinder 7, cylinder
The enclosure space that body 7 and airflow plate are constituted is airflow channel 14, and the lower section of crossflow plate 6 is fixedly connected with cabinet 8, cabinet 8
Internal activity be connected with portable pillar 9, the surface of portable pillar 9 is socketed with spring 10, and the left side of spool 4 offers plenum duct
