Voorbeeldzinnen
- Air intake valve if fitted [5]
- orifice valve and filler air dust
- The air intake valve is the control valve for the pneumatic governor of the injection pump.
- Air control valve, consisting of a stepping motor and a valve pintle, for the regulation of idle air flow in fuel injection engines
- p Flowing air pressure to pressure relief valve — in kPa absolute (recorded gauge pressure plus recorded barometric pressure).
- With the valve over the sample vessel open, suction is applied for several minutes to remove the air.
- The air pressure to the flowmeter is to be controlled by a suitable valve installed in the air-supply piping ahead of the flowmeter.
- With the valve in the closed position assumed as the result of normal operation, air or nitrogen at the specified test pressure is to be applied to the valve inlet for a test period of not less than 2 minutes.
- After all preparations for flow capacity tests have been made, the valve in the air-supply line is to be opened slowly and the pressure to the valve under test is to be increased to the appropriate flow rating pressure.
- If the special device is pneumatic, it must be fitted with a compressed air reservoir protected by a non-return valve.
- PB is not required when using a butterfly valve. PB may be used to to measure the dilution air flow, if calibrated.
- From the recorded data and the known orifice coefficient of the flowmeter, the air-flow capacity of the pressure relief valve tested is to be calculated using the following formula:
- The connection is to be made using a length of rubber hose between the pressure gauge and the pressure take-off, with a valve installed at the gauge inlet to permit bleeding air from the system.
- Three samples of each size of valve are to be subjected to these tests. The tests are to be made with air, and separate tests are to be run with each sample mounted vertically and horizontally.
- With the valve in the closed position assumed as the result of normal operation, air or nitrogen at the specified test pressure is to be applied to the valve inlet for a test period of not less than 2 minutes. During this time, the vertical position of the graduated cylinder is to be adjusted, if necessary, to maintain the same water level within and exterior to it.
