Drawings
Fig. 1 is a schematic view of a safety quick connector provided by the utility model.
As shown in the figure, the device comprises a 1-sampling tube, a 2-gas detector, a 3-signal wire, a 4-probe, a 5-fixing point, a 6-safety rope, a 7-fixer, an 8-quick connector female head and a 9-quick connector male head.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Example 1
As shown in fig. 1, a safety quick coupling, comprising: the sampling tube comprises a sampling tube 1, a quick connector female head 8, a quick connector male head 9 and a safety rope 6, wherein the quick connector female head 8 is arranged at one end of the sampling tube 1, the quick connector male head 9 is matched and connected with the quick connector female head 8, and the safety rope 6 is connected to the sampling tube 1; the safety line 6 has elasticity.
Example 2
The one end of sampling tube 1 is equipped with the sampling joint, quick-operation joint female 8 connect in on the sampling joint, the one end of safety rope 6 is fixed point 5, fixed point 5 is total 4, fixed point 5 with sampling joint fixed connection, the other end of safety rope 6 is fixer 7, fixer 7 is for colluding the claw, fixer 7 can dismantle with peripheral object and be connected.
Example 3
A gas detection device is arranged on the sampling tube 1 and is used for detecting gas leakage; the gas detection device is a hydrogen sulfide detection device; the gas detection device includes: gas detection appearance 2, signal line 3 and probe 4, gas detection appearance 2 and probe 4 are located respectively the both ends of signal line 3, signal line 3 twine in on the sampling tube 1, probe 4 is located the female head of quick-operation joint next door 8.
The specific working process is as follows:
example 4
Before sample introduction, the male quick-connector 9 is arranged on a sampling valve, a screw cap of the female quick-connector 8 is pulled backwards, and the male quick-connector 9 is pushed into the female quick-connector for connection; hooking the hook claw on a sampling valve, and opening the sampling valve for detection;
