Description
Technical field
It the utility model is related 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, rainwater weather
Can be burnt human body skin.Whether monitoring ammonia is leaked with valve at present, is typically detected using portable ammonia detection alarm.
Patrolman carries portable ammonia detection alarm, at any time monitoring field air, during inspection, because portable detector detects
Distance is too short, it is necessary to could obtain more reliable data close to ammonia valve, if any leakage, having on human body does not influence yet not smallly；Such as
There are wind, rain in Guo An areas, and that portable ammonia detection alarm is difficult and alarm, and because the flowing of outdoor air, this
The actual leakage value of the numerical value and valve of the detection of sample 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 are 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.
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, ammonia gas sensor can be installed and sense ammonia leakage, reduce the bonnet for the ammonia valve that parts pollute.
The technical scheme in the invention for solving the above technical problem is：A kind of bonnet of ammonia valve, set in bonnet
It is equipped with valve rod mounting hole；It is characterized in that：Described bonnet is made up of bottom flange and bonnet,；Bonnet, is located on bottom flange
Side, the bottom of bonnet, and the top of bottom flange are fixed；Gland nut mounting hole, valve rod are sequentially provided with bonnet, from top to bottom
Nut mounting hole, guide sleeve mounting hole, gland mounting hole and filler mounting hole；The side of bonnet, is provided with ammonia sensing
Device position and armored cassette position；Ammonia gas sensor interface, ammonia gas sensor interface and valve rod are provided with ammonia gas sensor position
Mounting hole connects, 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, described in the utility model and bottom flange.
The utility model the utility model compared with prior art, has 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
Space ammonia gas sensor component is installed, be common valve cover structure is unexistent.
2nd, gland nut mounting hole, valve stem nut mounting hole, guide sleeve mounting hole, gland installation are provided with bonnet,
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 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, armored cassette position cover ammonia gas sensor interface, and the armored cassette being so arranged on armored cassette position just covers
Ammonia gas sensor, debris damage caused by accidental explosion can be effectively prevented to people or thing.
5th, ammonia gas sensor parts are conveniently replaceable, effectively save maintenance time, reduce cost.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the utility model embodiment bonnet,.
Fig. 2 is the cross section structure diagram of the utility model embodiment bottom flange.
Fig. 3 is the cross section structure diagram that the utility model embodiment 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 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. 4, the utility model embodiment 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 weld.
Gland nut mounting hole 81, valve stem nut mounting hole 82, guide sleeve installation are sequentially provided with bonnet, 8 from top to bottom
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
