Model utility content
The purpose of this utility model is intended to overcome the problems such as the weak heat-dissipating that existing Pneumatic film sleeve modulating valve exists, and provides a kind of heat radiating type Pneumatic film sleeve modulating valve.
For this reason, the utility model is by the following technical solutions: heat radiating type Pneumatic film sleeve modulating valve, comprise valve body, valve rod, valve gap and air bladder final controlling element, described valve body is provided with left import and export, right import and export, the inner connectivity part of left import and export and right import and export is provided with sleeve, the spool that barrel bore is arranged with described valve rod front end coordinates, and valve rod controls stroke through described valve gap by described air bladder final controlling element; It is characterized in that, body top is fixed on by screw in described valve gap bottom, and the stage casing of valve gap forms cylindrical section, and the periphery of cylindrical section arranges multiple radiating fin, is separated bottom radiating fin by spacer.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristics.
The described tapered shape in spool upper end.
Bottom described valve gap, indent forms restraining groove, and the through hole that restraining groove and described valve rod install valve gap is through, and the valve stem part being in restraining groove is provided with spacing flange, thus limits the displacement of valve rod by restraining groove.
The passage of described left import and export and right import and export is curved channel
Described valve gap top indent forms filler and fills chamber, and filler is filled in chamber to arrange filler and shored by isolating ring and mounted cover, thus prevents air bladder final controlling element air chamber from leaking gas.
Described valve rod upper portion is fixedly installed pointer, and the upper end of described bonnet is fixedly installed U-shaped support, this U-shaped support is provided with the lifting travel scale-board of cooperation corresponding with pointer.
The opening that described sleeve and described left import and export are communicated with right import and export is arranged at the sidepiece of sleeve.
Use the utility model can reach following beneficial effect: the utility model by arranging radiating fin on valve gap, thus solve the problem that Pneumatic film sleeve modulating valve dispels the heat to periphery, thus can make Pneumatic film sleeve modulating valve-60 ~+560 DEG C occasion use, add the practicability of Pneumatic film sleeve modulating valve, improve its high-low temperature resistant ability, extend the working life of Pneumatic film sleeve modulating valve.
