Description
Technical field
The utility model relates to the explosion-proof sampling apparatus of gas, specifically a kind of thief rod.
Background technology
Factories and miness and other contain the Work places of explosion hazard gas, need to carry out sampling analysis to gas.At present, to the most complex structure of device that the gas of factories and miness Work places is sampled in prior art, production manufacturing cost is higher.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of thief rod, and this thief rod is simple to operate, safe and reliable, be easy to carry.
According to the technical solution of the utility model: a kind of thief rod, it is characterized in that: comprise sampling pipe, ring, sealing adaptor and filtering head, described sampling pipe is the more piece sleeve pipe of hollow, between sampling pipe rear end, adjacent two sleeve pipes by ring separately, often save sleeve pipe front end and all fix a sealing adaptor, be provided with O-ring seal between described sealing adaptor and corresponding sleeve pipe, the inner sleeve of sampling pipe is connected with filtering head, sampling pipe back end circumference surface is fastenedly connected handle.
As further improvement of the utility model, the faying face of adjacent two sealing adaptors abuts against together.
As further improvement of the utility model, the endoporus of described handle and the endoporus of sampling pipe connect.
As further improvement of the utility model, described filtering head is formed with cavity.
Technique effect of the present utility model is: the utility model product structure is simple, reasonable in design, in use has that little, the load capacity of sampling air flow pulsation is large, stability of flow, simple to operate, safe and reliable, the feature such as be easy to carry.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the topology view of the utility model handle part.
Fig. 3 is the topology view at the utility model filtering head position.
Fig. 4 is the topology view of the utility model sealing adaptor part.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1 ~ 4, comprise sampling pipe 1, ring 2, sealing adaptor 3, filtering head 4, cavity 4-1, handle 5, O-ring seal 6 etc.
As shown in Fig. 1 ~ 4, the utility model is a kind of thief rod, comprise sampling pipe 1, ring 2, sealing adaptor 3 and filtering head 4, described sampling pipe 1 is the more piece sleeve pipe of hollow, between sampling pipe 1 rear end, adjacent two sleeve pipes by ring 2 separately, often save sleeve pipe front end and all fix a sealing adaptor 3, between described sealing adaptor 3 and corresponding sleeve pipe, be provided with O-ring seal 6, the inner sleeve of sampling pipe 1 is connected with filtering head 4, sampling pipe 1 back end circumference surface is fastenedly connected handle 5.
The faying face of adjacent two sealing adaptors 3 abuts against together, and the endoporus of described handle 5 and the endoporus of sampling pipe 1 connect, and filtering head 4 is formed with cavity.
Sampling pipe 1 in the utility model is 304 materials, and adopt multilayer sleeve structure, be convenient to storage and carry, successively extract out during use, inside pipe wall is precise polished, and smooth finish reaches 0.4Ra, and flow resistance is low, and adsorption rate is low.Outer copper facing is to reach requirement of explosion proof.Sampling pipe 1 comprises outer tube and inner sleeve.
Ring 2 is polytetrafluoroethylene ring, and play guiding and inner wall protection effect, teflon has self-lubricating property, can reduce friction force when pipe stretches, and protects outer sleeve inner wall can not be pulled because firmly contacting the problem causing adsorption rate to rise.
Sealing adaptor 3 adopts the hard sealing means of roll extrusion with the outer tube of sampling pipe 1, and firm reliability is high.The motive seal mode of O-ring seal 6 is adopted with inner sleeve.
Filtering head 4 adopts copper material to make, and has primary filter, explosion-proof, the feature that flow area is large.Employing is threaded and is convenient to change.
Handle 5 is copper handle, and roll extrusion seals, and afterbody with connecting hose, or adopts teflon handle interference hot jacket firm with Pneumatic quick connector, afterbody with Pneumatic quick connector with connecting hose.
