Abstract
The utility model provides a kind of blast resistance construction of ammonia valve, and its is reasonable in design, explosion-proof.A kind of blast resistance construction of ammonia valve, including bonnet, it is characterised in that：Also include armored cassette；The side of described bonnet is provided with ammonia gas sensor interface；Armored cassette is arranged on bonnet, and armored cassette covers ammonia gas sensor interface.
Description
Technical field
It the utility model is related to a kind of blast resistance construction of ammonia valve.
Background technology
Ammonia is widely used in the fields such as control ammonia, ammoniacal liquor and combustion gas with valve, such as Application No. 201610553111.0
Chinese patent.
The ammonia valve of prior art has the following disadvantages：Ammonia easily explodes in a narrow and small, closed environment, therefore works as
On the one hand there is a dielectric leakage, when the sensor in another aspect valve has electric discharge phenomena, two aspects simultaneously occur that blast can be produced,
But existing ammonia valve does not possess the explosion prevention function of sensor.
Utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and provides a kind of structure design and close
Reason, the blast resistance construction of explosion-proof ammonia valve.
The technical scheme in the invention for solving the above technical problem is：A kind of blast resistance construction of ammonia valve, including
Bonnet, it is characterised in that：Also include armored cassette；The side of described bonnet is provided with ammonia gas sensor interface；Armored cassette is installed
On bonnet, and armored cassette covers ammonia gas sensor interface.
Armored cassette described in the utility model includes box body and lid；Box body is fixed on the side of bonnet,；Lid is fixed
On box body, box body is sealed.
The bottom of box body described in the utility model is fixedly installed mounting post.
The bottom surface of box body described in the utility model is provided with box body mounting hole, and bolt, spiral shell are provided with box body mounting hole
Box body is fixed on the side of bonnet, by bolt.
The side and bottom surface of box body described in the utility model are provided with wiring hole.
The utility model the utility model compared with prior art, has advantages below and effect：
1st, ammonia gas sensor is may be provided with ammonia gas sensor interface, when medium does not also penetrate into filler, ammonia sensing
Device can produce signal the very first time.
2nd, when on the one hand there is dielectric leakage, another aspect ammonia gas sensor has electric discharge phenomena, and two aspects occur producing simultaneously
Raw blast, so armored cassette covers ammonia gas sensor interface and can effectively prevented after accidental explosion caused by ammonia gas sensor
Debris damage is to people or thing.
3rd, the structure of bonnet and armored cassette, ammonia gas sensor parts is conveniently replaceable, maintenance time is effectively saved, reduces into
This.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model embodiment is arranged on valve.
Fig. 2 is the dimensional structure diagram of the utility model embodiment box body.
Fig. 3 is the positive structure diagram of the utility model embodiment box body.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment, and following examples are pair
It is of the present utility model explanation and the utility model is not limited to following examples.
Referring to Fig. 1-Fig. 3, the utility model includes bonnet 1 and armored cassette 2.
The side of bonnet 1 is provided with ammonia gas sensor interface 3.Ammonia gas sensor interface 3 is used to install ammonia gas sensor 4.
When bellows component produces breakage, filler lower section has medium to be flowed out from valve rod and bellows component junction and reaches finite concentration
When, ammonia gas sensor 22 detects these media and produces current signal to the control panel 5 that is attached thereto, at control panel 5
The leakage value of medium can be delivered to terminal after reason.
Control panel 5 is arranged in armored cassette 2.Armored cassette 2 includes box body 21 and lid 22.
The bottom of box body 21 is fixedly installed mounting post 23, and threaded mounting hole, screw and screw thread peace are provided with mounting post 23
Control panel 5 is fixed in mounting post 23 by the connection of dress hole, control panel 5 is fixed in box body 21.Mounting post 23 causes control
Panel 5 processed is vacantly in box body 21, and control panel 5 does not contact with the bottom surface of box body 21, and heat dispersion is more preferable.
The side and bottom surface of box body 21 are provided with wiring hole 24, and wiring hole 24 is used for the electricity for installing ammonia gas sensor component
Line.
The bottom surface of box body 21 is additionally provided with box body mounting hole 25, is provided with bolt in box body mounting hole 25, and bolt is by box body
21 are fixed on the side of bonnet 1, and the structure is easy to disassemble and repairs.Because the installation direction of armored cassette 2 requires, so size is set
Meter has added error-proofing technique.Armored cassette 2 covers ammonia gas sensor interface 3.
Lid 22 is screwed on box body 21, and box body 21 is sealed.
Above content described in this specification is only to the utility model structure example explanation；Moreover,
The title that the utility model each several part is taken can also be different, it is all according to the utility model patent conceive described construction, feature and
The equivalent or simple change that principle is done, is included in the protection domain of the utility model patent.
