The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of pneumatic sphere camflex valve, it is characterized in that: comprise valve body, in described valve body, be provided with valve rod, the lower end of described valve rod is provided with spool, described spool is close to valve interior wall, the top of described valve body is provided with supporting frame, described valve rod runs through support frame as described above, above support frame as described above, be provided with actuator, above described actuator, be provided with valve positioner, described valve positioner comprises shell, described outer casing bottom is provided with spacing hole, described valve rod is positioned at described spacing hole, in described shell, a side is provided with magnetoelectricity assembly, described magnetoelectricity assembly top is connected with feedback spring, described magnetoelectricity assembly top is provided with torque motor, between described torque motor and valve rod, be provided with feedback rod, described feedback rod is connected with range adjuster, in the middle of described range adjuster, be provided with adjustment bolt, described range adjuster top is provided with adjusting knob, described outer shell outer wall is fixed with terminal box, incoming pressure table, delivery gauge, between described incoming pressure table and described torque motor, be provided with baffle plate A, between described delivery gauge and described torque motor, be provided with baffle plate B, described baffle plate B is connected with economizer.
Described outer casing inner wall is covered with explosion-proof layer.
One side of described shell is provided with exhaust port, and described exhaust port place is provided with block.
Described spool is eccentric semi-spherical spool.
The beneficial effects of the utility model are:
1 valve positioner and pneumatic control valve support the use, accurately the operation of regulating and controlling valve.
2 adopt spring reset type structure, and low cost of manufacture is easy to maintenance.
3 magnetoelectricity assemblies adopt moving-coil structure, reliable, stable, good linearity.
4 the utility model structure improvements, multiple functional, and compact structure, volume are small and exquisite, easy for installation.
Arranging of 5 supporting frames can make valve location and installation more firm.
6 adopt eccentric semi-spherical spool, and resistance is little, can open fast or close.
7 positioning work pieces adopt internal whorl to be connected with valve rod, have changed the mode connecting in positioning work piece outside at present, make connection more firm, are not prone to fracture.
The setting of 8 explosion-proof layers, can avoid because flammable explosive gas or liquid in pipe infiltrate positioning work piece, thereby security incident occurs.
The air accumulation that the arranging of 9 exhaust ports can prevent in pipeline in positioning work piece, thereby produce gas pressure, affect the work of positioning work piece.
