the tongue of the control frame 3 falls into the groove of the cone pulley of the timer, the shaft 5 leaves the center of the instrument, and the core rod 3 can move upwards under the action of the spring, so that the upper flow channel and the lower flow channel of the sampling tube are closed simultaneously.

The clock casing is used to protect the timer and to connect the control mechanism and the rope cap, and the screw thread and the spigot are identical in structure, but the inner hole is asymmetrical in structure, so that the connection end is not replaceable.

The timer consists of hairspring, spring, wheel train, output shaft, upper and lower clamping plates, casing, cone pulley, etc. and is used to control the closing time of the upper and lower flow channels of the sampling tube. When the timer is installed into the clock shell after timing, the taper pin 1 on the control sleeve is inserted into the groove of the gasket on the timer, so that the tongue of the control frame 3 on the control sleeve automatically leans against the big outer circle of the cone pulley of the timer, and the timing accuracy is ensured.

The rope cap consists of rope cap head, rope cap joint and O-shaped ring, and is used to penetrate steel wire and suspend instrument.

The working principle of the sampler is as follows: under the condition that the upper flow channel and the lower flow channel of the sampling tube are opened, the instrument is lowered to a preset depth and stays for a certain time, when the timer runs for a preset time, the tongue of the control frame falls into the cone pulley groove of the timer, the central rod is out of restriction, the upper valve moves towards the direction of the timer under the action of spring force, and the upper flow channel is closed; meanwhile, the control sleeve leaves the spring sleeve under the drive of the upper valve, the bolt is out of restriction, and moves towards the cone under the action of the spring to close the lower flow passage, so that liquid (liquid sample) with a preset depth is obtained.

In conclusion, the double-air-chamber sampler has comprehensive functions, is safe and reliable, and is used for sampling by a well testing vehicle through a lubricator. The method is suitable for sampling various oil wells, oil and gas wells and water wells, and provides qualified samples for underground liquid component analysis. The advantages of the sampler can be better shown when the sampler is used for sampling deep wells, thick oil wells and open-hole wells.
