Description

Portable glass tube sampler with electromagnetic valve Technical Field The utility model relates to the technical field of liquid sampling, in particular to a portable glass tube sampler with a solenoid valve. Background For containers such as barreled liquid or liquid tank trucks, liquid samples of different depths need to be extracted. In particular, when sampling the liquid at the bottom of the barrel, it is common for the sampling personnel to directly cover the bottom of the glass tube with a finger and then quickly disclose the finger to allow the liquid to enter the glass tube. This operation requires space for the hands, which is disadvantageous for sampling the liquid near the bottom of the tub, and easily contaminates the glass tube and the sampled liquid. There is a need for a glass tube sampler that is simple to operate and suitable for use with large liquid depths. Disclosure of utility model The utility model aims to provide a glass tube sampler which is simple to operate and is suitable for taking liquid with large depth. In order to achieve the above object, the present utility model provides the following technical solutions: a portable glass tube sampler with electromagnetic valve comprises a waterproof battery box, an electromagnet part, a fixed ring, a valve rod, an axially-through glass tube, a sealing cover and a spring; The electromagnet component is provided with a waterproof single-coil electromagnet, and the waterproof battery box and the fixing ring are respectively and hermetically connected to the top end and the bottom end of the electromagnet component; the waterproof battery box is internally provided with a battery for supplying power to the electromagnet; A circle of limiting protrusions are arranged in the middle of the inner wall of the fixed ring; The valve rod and the limiting protrusion slide, a magnet cap is arranged at the top end of the valve rod, the limiting protrusion limits the valve rod to move downwards, and the spring is sleeved on the valve rod and is abutted between the magnet cap and the limiting protrusion; The glass tube and the fixing ring are detachably connected and sleeved into the glass tube, and the fixing ring is provided with a vent hole communicated with the glass tube; The valve rod penetrates through the glass tube, and the sealing cover capable of initially sealing the glass tube is fixed at the tail end of the valve rod; The waterproof battery box is provided with a switch of a switch electromagnet, the electromagnet is electrified, the valve rod moves downwards to enable the sealing cover to open the glass tube, and the electromagnet is powered off to enable the sealing cover to reset. Further, the glass tube cleaning device further comprises an outer tube cleaning ring made of rubber materials, wherein the outer tube cleaning ring can be attached to the glass tube and can move up and down, and the outer tube cleaning ring is provided with a handle plate. Further, the fixed ring is detachably connected with the electromagnet component. Further, the inner wall of the fixing ring, which is located below the limiting protrusion, is fixed with a fixing rubber ring, the fixing rubber ring is used for tightly sleeving the top end of the glass tube, and when an external force is applied, the glass tube can be pulled out from the fixing rubber ring. Further, the electromagnet component comprises an inner shell fixed with the electromagnet, the bottom end of the inner shell is provided with a circular ring, the circular ring is provided with threads and is in threaded connection with the inner wall of the fixed ring, and the valve rod is sleeved in the circular ring. In the technical scheme, the portable glass tube sampler with the electromagnetic valve has the following beneficial effects: The portable glass tube sampler is suitable for containers such as barreled liquid or liquid tank trucks, can extract liquid samples with different depths, and especially has a sampling port at the bottom end of a glass tube, and can be stretched into liquid samples with large depth. The glass tube is connected with a remote control switch, and the sampling port and the lofting port of the glass tube are shared and are all the bottom ends of the glass tube. The liquid in the glass tube is controlled by the switch to flow out from the sampling port, and the glass tube is used as a sampling bin. The electromagnetic valve adopts a single-coil electromagnetic valve, and the working principle of the electromagnetic valve is that the single-coil electromagnetic valve is provided with only one coil, and when the electromagnetic valve is electrified, the coil generates a magnetic field to enable the movable iron core to attract or push the valve rod. When the power is off, the magnetic field disappears, and the valve returns under the action of the spring. The electromagnetic valve can control the opening or closing of the sampling port.
