More Information
Summary:The invention relates to the field of petroleum engineering equipment, in particular to a gas-driven hydraulic disc type brake device. The gas-driven hydraulic disc type brake device comprises a first pneumatic hydraulic pump, a first check valve, a pressure reducing valve, a second check valve, a first solenoid valve, a second solenoid valve, a third solenoid valve and brake calipers. The first pneumatic hydraulic pump is connected with the first one-way valve. The first one-way valve is connected with the pressure reducing valve. The pressure reducing valve is connected with the second one-way valve. The second one-way valve is connected with the first solenoid valve. The first solenoid valve is connected with the second solenoid valve. The second solenoid valve is connected with the third solenoid valve. The third solenoid valve is connected with the brake calipers. The gas-driven hydraulic disc type brake device has the beneficial effects that the safety is improved, the size is reduced, the response time
