Abstract
The invention provides a kind of valve casing for safe valve exhaust, described valve casing is cylindrical in shape structure, at the valve port of safety valve (4), the valve casing is offering several steam vents (2) to the valve casing button on the side wall of its opening end (1).The steam vent of above-mentioned valve casing is opened in its housing side, solves the problems, such as that perforated area is limited first；And steam vent is easy to quickly from steam vent discharge, and make dust be not easy to fall into inside valve casing near the position of the valve port being connected with valve casing opening end in the waste gas of valve port output；In addition, the valve casing simple structure, convenient disassembly, using effect is good.
Description
Technical field
The present invention relates to safety valve technical field, and in particular to a kind of valve casing for safe valve exhaust.
Background technology
Valve casing is an important component of Anesthesia machine, and it plays a part of to protect safety valve.When using safety valve,
Since it is considered that the problem of exhaust, so needing the perforate on valve casing to be in communication with the outside, valve casing of the prior art is
Surface perforate thereon；But this kind of structure causes perforated area to be restricted, and dust easily is fallen into from tapping,
Further, since the gas of discharge has a stroke from top to bottom in valve casing, so that exhaust is slower.
The content of the invention
It is an object of the present invention to easily fall into dust, be vented slow skill to overcome existing valve casing to there is exhaust outlet
Art problem, the present invention devises a kind of valve casing for safe valve exhaust, can be exported safety valve using the valve casing
Gas quickly discharged along perforate, and avoid pollution.
To achieve the above object, a kind of valve casing for safe valve exhaust that the present invention is provided, described valve casing is in cylinder
Shape structure, at the valve port of safety valve, the valve casing is offered the valve casing button on the side wall of its opening end
Several steam vents.
Used as the further improvement of above-mentioned technical proposal, several described steam vents are uniformly distributed circumferentially.
Used as the further improvement of above-mentioned technical proposal, the opening end of the valve casing extends outward annular flange, leads to
Cross and the annular flange is pressed in valve port outer rim, valve casing is anchored on safety valve.
A kind of advantage of valve casing for safe valve exhaust of the invention is：
Because the steam vent of the valve casing in the present invention is opened in its housing side, solve what perforated area was limited first
Problem；And steam vent is easy near the position of the valve port being connected with valve casing opening end in the waste gas of valve port output
Quickly from steam vent discharge, and dust is set to be not easy to fall into inside valve casing；In addition, the valve casing simple structure,
Convenient disassembly, using effect is good.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the valve casing for safe valve exhaust.
Fig. 2 is the schematic diagram being installed on the valve casing shown in Fig. 1 on Anesthesia machine safety valve.

Specific embodiment
A kind of valve casing for safe valve exhaust of the present invention is carried out specifically with reference to the accompanying drawings and examples
It is bright.
As shown in figure 1, a kind of valve casing for safe valve exhaust of the invention, described valve casing is cylindrical in shape structure,
At the valve port of safety valve, the valve casing is offering several to the valve casing button on the side wall of its opening end 1
Steam vent 2.
In the present embodiment, the side bottom of the valve casing is provided with two circumferentially symmetrical steam vents 2, when having
Gas from safety valve discharge when, the gas through steam vent 2 from valve casing discharge, so as to play a part of Quick air-discharge.
In addition, as shown in figure 1, the opening end 1 of the valve casing can extend outward annular flange 3, by by the ring
Shape flange 3 is pressed in valve port outer rim, valve casing is anchored on safety valve 4.
As shown in Fig. 2 be installed on Anesthesia machine safety valve 4 using the valve casing of said structure, first by the opening of valve casing
End is directly sleeved on outside valve element, on the piece surface where annular flange 3 directly is pressed on into valve port with three screws 5
.In this embodiment, the structure and assembling mode of valve casing are not limited to the type shown in figure, connected mode
Not uniquely, other shapes are designed as the need for the valve casing is also dependent on installation.The arrangement mode of the steam vent in valve casing
And shape is alternatively other forms, the stomata of circular or rectangle is such as designed as.
Above-mentioned valve casing of the invention, by its lateral opening hole without being limited by perforated area, while in side
Bottom opening substantially increases the speed of safe valve exhaust to be close to valve port, and annular opening does not receive installation site
Limitation, as long as need exhaust device can use this form.
Valve casing of the invention is also applicable in other product for needing exhaust, system or technical fields.
It should be noted last that, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.Although
The present invention has been described in detail with reference to embodiment, it will be understood by those within the art that, to the present invention
Technical scheme modify or equivalent, without departure from the spirit and scope of technical solution of the present invention, its is equal
Should cover in the middle of scope of the presently claimed invention.
