Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A sampling device for a sampling valve is shown in figure 1-2 and comprises a sampling joint 1, a protective cover chuck 2, a protective cover 3 and a bottle support 4, wherein the sampling joint 1 is fixedly connected with a sampling pipeline, the protective cover chuck 2 is arranged on the sampling joint, a cavity for accommodating a sampling bottle is arranged in the protective cover 3, the bottle support 4 is rotatably arranged at the lower opening of the protective cover 3 through a pin shaft, a sampling bottle 9 is arranged in the cavity, and the bottle support 4 is rotated to open a lower buckle of the protective cover 3 so as to load and unload the sampling bottle; then the bottle support 4 is rotated to the lower part of the lower opening of the lower protective cover 3 to lift the sampling bottle 9. The protective cover 3 is clamped with the protective cover chuck 2.

In one embodiment, as shown in fig. 1-2, the sampling adapter 1 is provided with a vent needle 11 and a sampling needle 12. The exhaust needle 11 is communicated with the outside, and the sampling needle 11 is communicated with a sampling pipeline. So that the pressure inside the sampling bottle 9 is balanced with the outside pressure. Preferably, the exhaust needle 11 is opposite to the needle opening of the sampling needle 12, the exhaust needle 11 is longer in length and is beneficial to downward flow of the sample, the sampling needle 12 is shorter and is beneficial to upward discharge of the inert gas, and the sample is ensured not to splash to the sampling needle 12.

In one embodiment, as shown in fig. 1-2, a screw hole 21 is formed on the sidewall of the protection cap chuck 2, a fixing groove 13 is formed on the sidewall of the sampling adapter 1, a fixing screw 5 is disposed in the screw hole, and the fixing screw 5 is rotated so that the end of the fixing screw 5 is placed in the fixing groove 13, thereby fixedly connecting the sampling adapter 1 and the protection cap chuck 2. One end of the air release needle 11 may communicate with the fixing groove 13, and the gas in the sample bottle 9 may be discharged to the outside through the fixing groove 13.

In one embodiment, as shown in fig. 1-2, the side walls of the protection cap clip 2 are symmetrically provided with the fixing shafts 21, the upper opening of the protection cap 3 is provided with a groove 31 at a position corresponding to the position, and the opening of the groove 31 is provided with a clipping part 32. When the protective cover is installed, the fixing shaft 21 is inserted into the groove 31, and the protective cover 3 is rotated, so that the fixing shaft 21 is placed into the clamping and hanging part 32, and the protective cover 3 is hung on the fixing shaft 21. The snap-on part 32 is engaged with the fixed shaft 21 to realize the quick assembly and disassembly of the protective cover 3.

In one embodiment, as shown in fig. 1-2, the sampling bottle 9 comprises a body 91 and a cap 92, an opening is provided on the upper surface of the cap 92, a sealing gasket 93 is provided at the opening, and the cap 92 is mounted on the body 91. Typically, cap 92 is threadably engaged with body 91. During sampling, the exhaust needle 11 and the sampling needle 12 are inserted into the sampling bottle 9 through the sealing gasket 93, and during sampling, the sampling liquid enters the sampling bottle 9 through the sampling needle 12, and the excessive gas in the bottle is exhausted through the exhaust needle 11. During which the sample liquid does not spill out of the mouth of the sample bottle 9. After the sampling is completed, the external gas does not enter the sampling bottle 9.

In one embodiment, as shown in fig. 1-2, the diameter of the mouth of the sampling bottle 9 is smaller than the diameter of the body, and the inner wall of the protective cap 3 is provided with a clamping edge 33 extending inwards. By means of the difference in diameter of the sampling bottle 9, the neck opening can pass the locking edge 33 because of its small diameter. The diameter of the lower part is larger, so that the lower part cannot pass through the clamping edge; after the sampling of the sampling bottle 9 is finished, the sampling needle 2 and the exhaust needle 1 need to be pulled out, so that a relative pulling force exists; the sample vial 9 is retained within the cavity by the retaining lip 33, providing a downward pull on the sample vial 9.

In one embodiment, as shown in FIGS. 1-2, a viewing port 34 is provided in a sidewall of the shield 3. So that the staff can observe the sampling amount conveniently.

In one embodiment, for a chemically active sample, the sampling bottle 9 has a sealing gasket 93, which can be pre-filled with inert gas, and the sealing gasket can automatically seal after the sample is taken out of the sampling/venting needle, thereby protecting the sample from chemical reaction with air. The defect that the sampling result is inaccurate due to the chemical reaction between the common sampling sample and the components in the air is overcome.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
