The nozzle assembly of position device IP modules.
Utility model content
The purpose of this utility model is that, in order to solve shortcoming present in prior art, hairspring is operationally in tension-like
State, long-term tense can produce fatigue, such as uncompensated technique, and hairspring can fluff, and the one kind proposed is based on nozzle flapper smart valve
The nozzle assembly of door holder IP modules.
To achieve these goals, the utility model employs following technical scheme：
A kind of nozzle assembly based on nozzle flapper intelligent valve positioner IP modules of design, including component framework, it is described
Component framework is made up of side plate and framework platform, and the framework platform is inverted u-shaped, and the framework platform is installed on the upper of side plate
Portion, the upper end side of the framework platform is connected with fixed block by set screw, and the side of the framework platform passes through screw

Provided with guide rod, connected between the fixed block and stainless steel substrates by hairspring, the component framework is arranged right below coil, institute
State and baffle plate is fixedly connected with hairspring, magnet is provided between the coil and baffle plate, the upper end of the framework platform is provided with and gear
The corresponding nozzle of plate.
It is preferred that, the upper end side of the component framework is provided with arc groove, arc groove provided with protection pad, described
Arc groove is located at the underface of hairspring.
It is preferred that, the two ends of the hairspring are connected by connection sheet with fixed block and stainless steel substrates.
The utility model proposes a kind of nozzle assembly based on nozzle flapper intelligent valve positioner IP modules, beneficial effect
Fruit is：The regulated quantity of baffle plate is micron-sized, and the position of baffle plate is to tense to fix by hairspring, it is desirable to nature lower baffle plate
In plumbness, produce the magnetic force of different directions and size to change the distance between baffle plate and nozzle, hairspring using magnet
One end is fixed on fixed block, and the other end is fixed on stainless steel substrates, and stainless steel substrates stretch bending, meets the need of low-power consumption driving
Will；The rising-heat contracting-cold phenomenon of the fatigue and variation of ambient temperature in hairspring cinching process is compensated simultaneously, it is ensured that nozzle flapper position
Put and do not moved during long-term use；When environment temperature declines, hairspring can be shunk, and stainless steel substrates can be drawn more curved, trip
Silk can be tightened up and will not break；When external environment temperature rises, hairspring, which can splash, to rise, and stainless steel substrates can recover, and pull on hairspring,
Ensure that baffle plate is vertical, so as to reach the flexible automatic compensation to hairspring, when component for long periods works, hairspring can produce fatigue,
Compensated again by the elasticity of stainless steel, be for the inclination angle of controllable register, it is ensured that debug using taper set screw
Nozzle flapper be in free plumbness, it is ensured that the bending of stainless steel substrates compensates come the tired and retractility to hairspring
Hairspring fixed form, greatly improve present apparatus service life, be that producer brings invisible benefit, be worth after promote make
With.
