Description
Technical field
The present invention relates to a kind of bonnet 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：
1st, after ammonia leakage certain time, nose, pharynx, the eye of people receive stimulation, may result in blindness, and rainwater weather can burn
Hinder human body skin.Whether monitoring ammonia is leaked with valve at present, is typically detected using portable ammonia detection alarm.Inspection
Personnel carry portable ammonia detection alarm, at any time monitoring field air, during inspection, due to portable detector detecting distance
It is too short, it is necessary to which more reliable data could be obtained close to ammonia valve, and if any leakage, having on human body does not influence yet not smallly；If ammonia
Qu Youfeng, rain, that portable ammonia detection alarm is difficult and alarm, and because the flowing of outdoor air, such
The actual leakage value of the numerical value and valve of detection misfits, meanwhile, artificial detection frequency is not high, does not accomplish constantly to monitor.
2nd, in the structure of current ammonia valve, the design of bonnet closely, by taking bellows structure as an example：The built-in ripple of bonnet
Line tube assembly, lower valve rod built in bellows component is then charged into filler, and filler upper end is gland, Anti-rotary block, upper valve successively
Bar, valve stem nut, handwheel or actuator.There is no position to lay ammonia gas sensor.
The content of the invention
It is an object of the invention to overcome above shortcomings in the prior art, and provide a kind of reasonable in design,
Ammonia gas sensor can be installed and sense ammonia leakage, reduce the bonnet for the ammonia valve that parts pollute.
The present invention the used technical scheme that solves the above problems is：It is provided with a kind of bonnet of ammonia valve, bonnet
Valve rod mounting hole；It is characterized in that：Described bonnet is made up of bottom flange and bonnet,；Bonnet, is located above bottom flange, on
The bottom of bonnet and the top of bottom flange are fixed；Gland nut mounting hole, valve stem nut are sequentially provided with bonnet, from top to bottom
Mounting hole, guide sleeve mounting hole, gland mounting hole and filler mounting hole；The side of bonnet, is provided with ammonia gas sensor position
Put and armored cassette position；Ammonia gas sensor interface is provided with ammonia gas sensor position, ammonia gas sensor interface is installed with valve rod
Hole is connected, and positioned at the lower section of filler mounting hole；Armored cassette position covers ammonia gas sensor interface.
Chamfering is provided with the top of the bottom of bonnet, of the present invention and bottom flange.
Invention compared with prior art, with advantages below and effect：
1st, bonnet is made up of bottom flange and bonnet, forms the structure of segmented, and the bonnet of segmented has reserved enough skies
Between ammonia gas sensor component is installed, be common valve cover structure is unexistent.
2nd, installed in bonnet, provided with gland nut mounting hole, valve stem nut mounting hole, guide sleeve mounting hole, gland
Hole and filler mounting hole so that gland nut, valve stem nut, guide sleeve, gland and filler may be contained within bonnet, outside
Boundary's environment can not pollute easily plays these parts, reduces the pollution of parts, improves service life.
3rd, ammonia gas sensor can be set in the ammonia gas sensor interface of the lower section of filler mounting hole, when medium does not ooze also
When arriving filler thoroughly, ammonia gas sensor can produce signal the very first time.
4th, when one side has dielectric leakage, another aspect ammonia gas sensor has electric discharge phenomena, and producing occur simultaneously in two aspects
Raw blast, armored cassette position covers ammonia gas sensor interface, and the armored cassette being so arranged on armored cassette position is just covered
Ammonia gas sensor, can effectively prevent debris damage produced by accidental explosion to people or thing.
5th, ammonia gas sensor parts are conveniently replaceable, maintenance time is effectively saved, cost is reduced.

Fig. 2 is the cross section structure diagram of bottom flange of the embodiment of the present invention.
Fig. 3 is the cross section structure diagram that the embodiment of the present invention is arranged on valve.
Fig. 4 is the cross section structure diagram of Fig. 3 partial rear.
Embodiment
Below in conjunction with the accompanying drawings and the present invention is described in further detail by embodiment, following examples are to this hair
Bright explanation and the invention is not limited in following examples.
Referring to Fig. 1-Fig. 4, the embodiment of the present invention includes bonnet 7.
Valve rod mounting hole 9 is provided with bonnet 7, the valve rod 3 of valve is arranged in valve rod mounting hole 9.
Bonnet 7 is made up of bottom flange 6 and bonnet, 8.Bonnet, 8 is located at the top of bottom flange 6, and the bottom of bonnet, 8 is with
The top of bonnet 6 is welded and fixed.The bottom of bonnet, 8 and the top of bottom flange 6 are provided with chamfering, are easy to welding.
Gland nut mounting hole 81, valve stem nut mounting hole 82, guide sleeve are sequentially provided with bonnet, 8 from top to bottom to install
Hole 83, gland mounting hole 84 and filler mounting hole 85.
The valve stem nut 13 of valve is arranged in valve stem nut mounting hole 82.Handwheel or actuator pass through valve stem nut 13
It is connected with valve rod 3.
The gland nut 5 of valve is arranged in gland nut mounting hole 81.Gland nut 5 is pressed on valve stem nut 13, is prevented
Only valve stem nut 13 departs from from valve stem nut mounting hole 82.
The filler 10 of valve is arranged in filler mounting hole 85, and gland 11 is arranged in gland mounting hole 84.
The bottom of filler pressing sleeve 11 is pressed on filler 10, and filler 10 is arranged in bonnet 7 by gland 11.
The guide sleeve 12 of valve is arranged in guide sleeve mounting hole 83.Guide sleeve 12 is connected with valve rod 3.
The side of bonnet, 8 is provided with ammonia gas sensor position and armored cassette position.
Ammonia gas sensor interface 1 is provided with ammonia gas sensor position, ammonia gas sensor interface 1 connects with valve rod mounting hole 9
It is logical, and positioned at the lower section of filler mounting hole 85.Ammonia gas sensor 3 is fixedly mounted in ammonia gas sensor interface 1.When bellows group
Part 4 produces breakage, when the lower section of filler 10 has the medium to be flowed out from valve rod 3 and the junction of bellows component 4 and reach finite concentration, ammonia
Gas sensor 3 can detect these media.
Armored cassette position covers ammonia gas sensor interface, and the armored cassette 2 being so arranged on armored cassette position is just covered
Firmly ammonia gas sensor 3, can effectively prevent debris damage produced by accidental explosion to people or thing.
Above content described in this specification is only to structure example explanation of the present invention；Moreover, this hair
