Description

Protective Structure of Sampling Pipe in Tank Truck

technical field

The invention relates to a protective structure for a sampling tube of a tanker, in particular to a protective structure for a sampling tube of a tanker that can improve the use effect of the sampling tube.

Background technique

As shown in Fig. 1 and Fig. 2, after the tanker transporting petrochemical substances such as gasoline, etc. is delivered to the destination, the receiver will take samples to confirm that the petrochemical substances transported are correct. Therefore, the operator will connect a sampling pipe 1 between the conveying pipe PS of the tanker and the receiving pipe PR of the receiver. The central part of the sampling pipe 1 runs through a flow hole 11, and the sampling pipe 1 has fixed holes around the flow hole 11. Used to clamp the face 12, the sampling tube 1 protrudes a sampling output connector 13 at the upper end, and the sampling output connector 13 of the sampling tube 1 can be screwed for the sampling output tube SP.

As shown in Fig. 1 and Fig. 2, the first piercing hole PR11 of the first flange PR1 of the receiving pipe PR and the second piercing hole of the second flange PS1 of the delivery pipe PS are pierced by bolts S Screwed after PS11, so that the sampling pipe 1 can be stably held between the first flange PR1 of the receiving pipe PR and the second flange PS1 of the delivery pipe PS; when sampling, the operator only It is necessary to control the control valve (not shown in the figure) on the sampling pipe SP to take samples, so as to confirm whether the petrochemicals in the tank car are the desired petrochemicals.

The above-mentioned conventional tank truck sampling method can certainly achieve the purpose of sampling; however, the above-mentioned conventional sampling method, when the sampling pipe 1 is positioned between the first flange PR1 of the receiving pipe PR and the delivery pipe PS in a pinched manner, When between the second flange PS1 of the receiving pipe PR, the first piercing hole PR11 of the first flange PR1 of the receiving pipe PR and the first piercing hole PR11 of the second flange PS1 of the delivery pipe PS are first pierced by a bolt S 2. Pierce the hole PS11, and then connect it by screwing. However, the sampling tube 1 has a certain weight and the seat is a circular body, so the sampling tube 1 is connected by the receiving tube PR and the delivery tube PS. During the action, the sampling tube 1 is often caused to drop directly, and the sampling output joint 13 located at the upper end of the sampling tube 1 is hit, thereby causing the base of the connection between the sampling output joint 13 and the sampling tube 1 to be damaged. In serious cases, it will cause leakage at the base of the connection between the sampling output joint 13 and the sampling tube 1 during sampling, which will cause the petrochemicals to seep out and cause serious damage to the human body or the environment.

Therefore, how to provide a protective structure for the sampling tube of the tanker, so as to have a better positioning effect on the sampling tube before connection, so as to prevent the sampling output joint from being damaged, has become an urgent problem to be solved by the industry.
