The structure of handwheel is identical with the structure for the device that I is taken charge of in patented ZL201520641885.3.
The utility model is a kind of new core level manual diaphragm valve, compact overall structure, has saved installing space, is mitigated
The load that is brought to pipeline；Unique seal with buss structure effectively can avoid medium from leaking outside, while can also avoid in special work
Condition lower valve stem nut contacts with medium and is corroded and produces the risk of security incident；Middle flange is using being rigidly connected, by pre-
The constant compression amount first set has reached reliable sealing property, eliminates the extraneous additional load come to mode separation strapping, improves
The life-span of barrier film.The valve is to carry out rotary valve rod with the manually operated overload protection handwheel for having set moment of torsion, controls opening and closing element
Upper-lower position；It is related between handwheel and valve rod when the moment of torsion of handwheel input exceedes the setting torque value of overload protection handwheel
Part skids automatically, it is achieved thereby that carry out opening/shutting valve with rated moment, improve valve service life and sealing it is reliable
Property.
Compared with prior art, the utility model has advantages below：
(1) it is safe and reliable：The isostructural setting of bushing, valve stem nut on bonnet, ensure that motion thread and valve rod spiral shell
Line is isolated on seal with buss, and so, even if barrier film is damaged, medium will not also leak and corrode screw thread and valve stem nut,
So as to avoid the risk that valve stem nut contact medium is corroded.
(2) diaphragm seal effect is good, and stability is high：The setting of positive stop lug boss on valve body and bonnet and it is rigidly connected,
Membrane compresses amount and overall fitted position can be accurately controlled very much, barrier film flange compression set rate is tended towards stability.
(3) barrier film is provided with sealed muscle and ribs, and the sealing stability and structural strength of barrier film are more preferable.
(4) overload protection：Overload protection handwheel avoid valve input torque it is excessive and cause valve part damage ask
Topic, carrys out opening/shutting valve not against stroke instruction so that operation is safer, improves the service life of valve.The part is adjusted
Ability is strong, has a wide range of application.
(5) it is easy to maintenance：Complete machine structure is simple, can complete to dismantle without specific purpose tool.Each crucial damageable zone is equal
Using modularized design；When not exclusively failure occurs for the overload protection handwheel such as valve, easily simply it can edit again specified
Moment of torsion, you can normal opening/shutting valve；When occurring entirely ineffective, it in emergency circumstances can rotate main part with spanner and be revolved with this
Rotating valve rod reaches the purpose of opening/shutting valve, and during conditions permit to be repaired, the parts of damage can be changed.Seal with buss
Design can directly be changed in the case where that need not remove valve rod；Barrier film, which only needs loose unloading to disassemble fastener, can complete to change.
(6) simple operation：Due to eliminating the annexes such as indicating arm and employing overload protection handwheel, when overload protection handwheel
Illustrate that valve has been fully opened or closed during automatic skidding.Insufficient light or can not observe valve opening and closing instruction environment
Under, solve the problems, such as merely with the indicating graduation of indicating arm come judge valve whether completely open and close.
