The conduction oil special utility that the utility model is obtained lengthens neck bellows stop valve, has the characteristics that：To handwheel
Material, outward appearance and thickness are shaped and select thick high-quality iron sheet compacting to form again, prevent handwheel in use and transportation
The possibility of middle modification.Replace old lateral pin from high-quality wind spring pin, it is ensured that flap is difficult to take off in opening-closing process
Fall.Valve stem nut uses traveling nut, changes original pin configuration, using D type structures, is fitted close with handwheel.Road in valve
Pad uses high-quality and efficient composite pad（304+ soft graphites）, road sealing effectiveness in raising, it is ensured that the reliability of middle road sealing.
Valve neck is designed as lengthening neck structure, and bellows is arranged in long-neck, reduces the chance that bellows is contacted with conduction oil, together
When bellows heating temperature.Bellows uses advantage material SS316L, and improves bellows stroke, and maximum to the greatest extent is improved
The service life of bellows.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment：
As shown in figure 1, the conduction oil special utility that the present embodiment is provided lengthens neck bellows stop valve, including valve body 1, peace
Bonnet 6, valve rod 15 and the end of the valve rod 15 fixation company shuttled in valve body 1 combines rear interior cavity with bonnet 6 above valve body
The handwheel 17 for connecing and the flap 2 for being connected with valve stem end in valve body and being contacted with sealing surface on valve body, in bonnet 6 and valve
Sleeve 14 is installed between body, is fixed by hex(agonal)screw 7 or stud 8 between bonnet 6 and sleeve 14, positioned at bonnet 6 with
Sleeve 14 between valve body 1 is formed has independent sealed intracavity space, and sleeve bottom is provided with the through hole for the activity of valve rod 15, should
The two ends of sleeve are fixedly connected with the valve body with bonnet respectively, and bellows component 4 is provided with sleeve, and bellows component is sheathed on
Valve rod outer end is enclosed.
Bellows component 4：SS316L bellowss, its Main Function is that dual-seal is constituted together with filler, isolates and hinders
The possibility that only medium is leaked from filler., this lengthens bellows and is located in lengthening neck, lengthens neck medium and bellows point
Leave and, thus be avoided that etch of the conduction oil to bellows（The easy fouling of conduction oil causes overheat burning, then causes bellows to become
Type, cracking）, when conduction oil is flowed in runner with 350 degree, the temperature for lengthening the bellows in neck is less than 350 degree, SS316L
Under such temperature conditionss, it is unlikely to deform, ftractures, substantially increase the service life of bellows, so as to extends the work of valve
Make service life
Bonnet 6：Bonnet is lengthened, its effect is to improve bonnet thermal diffusivity, it is to avoid when staff is in unlatching handwheel because of bonnet temperature
Spend the possibility so as to iron hand high.
Sleeve 14：Neck is lengthened, its Main Function is spacer medium and bellows, prevents conduction oil from excessively being connect with bellows
Touch, so as to reduce the possibility that bellows overheat burning causes deformation and cracking.Work service life
Handwheel 17：After D types handwheel and the D types mouthful tight sealing engagement of nut 13, by tight split nut 18 and prosperous locking, such knot
Structure does not come off, with good reliability and durability.Work service life
Wind spring pin 3 is provided with flap 2, and is fixedly connected with valve rod 15 by wind spring pin 3.From high-quality wind spring pin
To replace old lateral pin, it is ensured that flap is difficult for drop-off in opening-closing process.
Pad 5 is provided with bonnet 6 and the cooperation of sleeve 14.The side end of bellows component 4 is placed on pad 5.Road in valve
Pad uses high-quality and efficient composite pad（304+ soft graphites）, road sealing effectiveness in raising, it is ensured that the reliability of middle road sealing.
The filler 9 for being positioned over valve rod outer end circle is provided with bonnet 6, a packing seal is installed on filler in bonnet
Gland 10 with valve rod, makes packing seal relatively reliable, is additionally provided with gland 10 on fixed and valve rod
Locating piece 10, locating piece 10 is fixed on valve rod 15 by resilient key 11.
For the reliability installed and flexibility, gland is fixed on bonnet 6 by eyelet bolt 16.17 sets of handwheel
It is connected in valve stem end and by locking nut.Hand wheel nut design more rationally, cancels pin fixed structure,
Handwheel 17 is made using metal material.Preferably, valve body, bonnet, sleeve outer surface are repressed metal
Appearance.The features such as it has high intensity, appearance looks elegant is shaped and is selected thick high-quality again to handwheel material, outward appearance and thickness
Iron sheet compacting is formed, and prevents handwheel from using the possibility with modification in transportation.
For the utility model person of an ordinary skill in the technical field, the utility model design is not being departed from
Under the premise of, its framework form can be flexible and changeable, simply makes some simple deduction or replace, should all be considered as belonging to by this reality
