Description

TECHNICAL FIELD

[0002] The pressure testing system, also known as a pressure resistance testing system, is an important testing means for ensuring the safe and reliable performance of hydraulic equipment. Various types of pipes, pressure vessels, valve bodies, and blowout preventers need to be subjected to pressure resistance testing, and only after passing the testing according to the inspection standards can they be used. At present, the blowout preventer is more subjected to pressure resistance testing. The pressure testing system thereof mainly comprises a hydraulic pump, an accumulator, a pressure reducing valve, a three-position four-way reversing valve, a pressure controller, an oil tank, and a standby power air pump, etc. During operation, the hydraulic oil in the oil tank enters the electric pump or the air pump through the valve and the filter, the electric pump or the air pump pressurizes the hydraulic oil and inputs it into the accumulator for storage, the capsule of each cylinder of the accumulator is pre-charged with nitrogen, when the oil pressure in the accumulator cylinder is increased to 21 MPa, the pressure controller controls the motor or the air pump to stop running, when the oil pressure in the cylinder is excessively reduced, the pressure controller starts the motor or the air pump to make the accumulator maintain the required pressure oil range, when the pressure oil in the accumulator enters the control manifold, it is reduced to 10.5 MPa by the pressure reducing valve and input into the reversing valve (three-position four-way reversing valve) manifold of the control blowout preventer and the hydraulic valve, by operating the handle of the reversing valve, the opening and closing actions of the corresponding blowout preventer can be realized; during pressure testing, the inlet of the pressure testing pipeline is connected with the double-sided pressure testing drill pipe gate, the outlet is connected with the lower drill pipe gate, and the high pressure output control is realized through the control valve of the pressure testing pipeline.

[0003] In detail, referring to the wireless remote control and high-pressure test function blowout preventer control device disclosed in Chinese Patent CN201588592U, the test device consists of a pneumatic hydraulic pump, an ultra-high pressure shut-off valve, a check valve, an overflow valve, and a color recorder. Two pneumatic hydraulic pumps are connected in series via check valves. The output port of the pneumatic hydraulic pumps is connected to a tee, which is connected to the overflow valve and the check valve respectively. The check valve is connected to the input port of the pneumatic hydraulic pump. The output port of the pneumatic hydraulic pump is connected to the check valve, which is connected to the tee. The tee is connected to the ultra-high pressure shut-off valve, which is connected to the test pressure four-way valve. The suction ratio of the 1:50 pneumatic hydraulic pump is... The water inlet is connected to the test fluid outside the oil tank. A tee is connected to the output port of the 1:50 pneumatic hydraulic pump, then to an overflow valve, and finally to a check valve. The check valve is connected to the input port of the 1:200 pneumatic hydraulic pump, and the output port of the 1:200 pneumatic hydraulic pump is connected to the check valve. The check valve is connected to a tee, which in turn connects to a rupture disc. The tee is then connected to an ultra-high pressure shut-off valve, which is connected to a test pressure four-way valve. One path of the four-way valve connects to a pressure gauge and a pressure sensor, which is connected to a color recorder via cable. The second path of the four-way valve connects to the ultra-high pressure shut-off valve (to release pressure after the test). The third path of the four-way valve connects to the valve to be tested. However, the testing and control of this device are independent, failing to maximize the utilization of the hydraulic pressure in the pipeline.
