A pneumatic vacuum valve is situated atop a cylinder or convenient working space utilized in conjunction with a pneumatic elevator. The vacuum valve has a coupling unit holding a diaphragm device for actuation of the diaphragm against a flow control opening. An Allen screw uses a simple regulation device to control the flow of air into a working chamber for expansion and contraction of the diaphragm device.
1. A vacuum valve system comprising:
a pneumatic elevator cylinder having a sealed cabin therein;
a diaphragm device attached at a top of the pneumatic elevator cylinder;
a plate of material situated above the diaphragm device;
a hollow tubular member attached at an end to the plate of material such that another end of the hollow tubular member extends downwards through a perforation of the diaphragm device into the elevator cylinder; and
an electromagnetic switch attached to a bottom of the hollow tubular member.
2. A vacuum valve system, comprising:
a pneumatic elevator cylinder having a sealed cabin therein;
a diaphragm device attached at a top of the pneumatic elevator cylinder;
a coupling unit within which the diaphragm device is situated;
a cap attached to the coupling unit; and
a regulation member attached to a top surface of the cap.
3. The vacuum valve system of claim 2 wherein the regulation member further comprises:
a passageway from a side of the regulation member to a bottom side of the regulation member.
4. The vacuum valve system of claim 3 wherein the regulation member further comprises:
a hole at a top of the regulation member intersecting the passageway.
5. The vacuum valve system of claim 4 , wherein the regulation member further comprises:
an adjustment member inserted in the hole.
6. A vacuum valve apparatus comprising:
a coupling unit having a top portion, a bottom portion, and a holding portion there between;
a diaphragm unit situated within a depression in the holding portion;
a cap attached to the top portion of the coupling unit;
a connection portion attached to the bottom portion of the coupling unit wherein the connection portion is also attached to a pneumatic elevator cylinder;
a sealing unit attached to a top region of the connection portion;
a plate of material situated above the diaphragm unit; and
a control member attached to the plate of material through a perforation in the diaphragm unit.
7. The vacuum valve apparatus of claim 6 , further comprising:
a regulation member attached to the cap.
8. The vacuum valve apparatus of claim 6 , wherein the control member further comprises an electromagnetic switch.
