Abstract
A pneumatic-controlled abrasive blasting system that includes a blast hose; and a deadman assembly coupled with the blast hose. The deadman assembly has a primary deadman valve; and a secondary deadman valve. There is an air source configured for fluid communication with each of the primary and secondary deadman valves and the blast hose. There is a regulator valve disposed between the deadman assembly and the air source. The regulator is configured to reduce the pressure of airflow to the deadman assembly.
Claims20
A pneumatic-controlled abrasive blasting system comprising:
- a blast hose;
- a deadman device coupled with the blast hose, the deadman device further comprising:
- a base frame;
- a primary deadman valve housed at least partially within the base frame, the primary deadman valve configured to move between a signal-flow position and a signal no-flow position;
- a trigger member movably coupled with the base frame, the trigger member comprising a first plunger cavity with a first plunger movably disposed therein;
- an air source configured for fluid communication with the primary deadman valve;
- a regulator valve disposed between the deadman device and the air source, and configured in fluid communication therewith;
- and
- a primary control valve in signal communication with the primary deadman valve, and also in fluid communication with the air source,
- wherein the regulator valve reduces pressure of a signal airflow to form a regulated signal airflow transferred to the primary deadman valve, and
- wherein the primary control valve comprises a respective activation pressure setting and a deactivation pressure setting.

A pneumatic-controlled abrasive blasting system comprising:
- a blast hose;
- a deadman assembly coupled with the blast hose, the deadman assembly further comprising:
- a base frame;
- a primary deadman valve housed at least partially within the base frame, the primary deadman valve movable between a signal-flow position and a signal no-flow position;
- a trigger member movably coupled with the base frame;
- an air source configured for fluid communication with the primary deadman valve;
- a regulator valve disposed between the deadman assembly and the air source, and configured in fluid communication therewith;
- an intermediate regulator valve disposed between the regulator valve and the air source, and configured in fluid communication therewith;
- a primary control valve in signal communication with the primary deadman valve and also in fluid communication with the air source,
- wherein the intermediate regulator reduces pressure of a signal airflow received from the air source to form an intermediate regulated pressure air signal that is transferred to the regulator valve,
- wherein the regulator valve reduces pressure of the intermediate regulated pressure air to form a second regulated air signal that is sent to the primary deadman valve, and
- wherein the primary control valve comprises a respective activation pressure setting and a deactivation pressure setting.
