Abstract
The invention relates to an explosion-proof screw cap type automatic gas detector, which comprises a detector body and an air inlet pipe communicated with the lower part of the detector body. The air inlet pipe is communicated with an explosion-proof screw cap, which includes a rotation pedestal in threaded connection with the air inlet pipe and an explosion-proof cap communicated with the rotation pedestal. The explosion-proof cap includes a cover shell communicated with the rotation pedestal and an explosion-proof shim disposed in the cover shell, the inner wall of which is equipped with at least one annular groove. And an explosion-proof seal ring is embedded in the annular groove. According to the invention, the explosion-proof screw cap type automatic gas detector designed with the explosion-proof cap can improve the safety performance during detection, and avoids potential safety hazards.
Description
Technical field
The present invention relates to the field of detector, especially a kind of explosion-proof cap-rotating type gas automatic tester.
Background technology
At present domestic when detecting for gases such as oxygen, acetylene, CO2, propane, all need to use detector, the detector that uses has a variety of at present, the most frequently used is exactly pressure detecting instrument, pressure detecting instrument, reading is fast, the response time is short, because these gases such as oxygen, acetylene, CO2, propane, belong to inflammable, explosive gas, when detecting, need use safety valve, because present safety valve does not possess explosion-proof function, in testing process, cause serious potential safety hazard easily.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the above-mentioned middle problem that exists, provide a kind of explosion-proof cap-rotating type gas automatic tester, its project organization is reasonable, security performance is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of explosion-proof cap-rotating type gas automatic tester, comprise that detector body and connection are in the draft tube of detector body bottom, be communicated with explosion-proof spiral cover on the described draft tube, explosion-proof spiral cover comprises the spiral cover base that is threaded mutually with draft tube, the explosion-proof cap that is connected with rotating base, explosion-proof cap comprises the lid shell that is connected with rotating base and is located at the explosion-proof pad that covers in the shell, offer at least one annular groove on the lid shell inwall, be equipped with explosive-proof sealed circle in the annular groove.
Offer two annular grooves on the described lid shell inwall.
The invention has the beneficial effects as follows: described a kind of explosion-proof cap-rotating type gas automatic tester, adopt the detector of this kind design, at explosion-proof cap of detector design, can in testing process, improve security performance, avoid producing potential safety hazard.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the one-piece construction synoptic diagram of a kind of explosion-proof cap-rotating type gas automatic tester of the present invention.
Accompanying drawing acceptance of the bid keep the score state as follows: 1, detector body, 2, draft tube, 31, the spiral cover base, 32-1, lid shell, 32-2, explosion-proof pad, 32-3, annular groove, 32-4, explosive-proof sealed circle.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of explosion-proof cap-rotating type gas automatic tester as shown in Figure 1, comprise that detector body 1 and connection are in the draft tube 2 of detector body 1 bottom, be communicated with explosion-proof spiral cover on the draft tube 2, explosion-proof spiral cover comprises the spiral cover base 31 that is threaded mutually with draft tube 2, the explosion-proof cap that is connected with rotating base 31, explosion-proof cap comprises the lid shell 32-1 that is connected with rotating base 31 and is located at the explosion-proof pad 32-2 that covers in the shell 32-1, offer two annular groove 32-3 on the lid shell 32-1 inwall, be equipped with explosive-proof sealed circle 32-4 in the annular groove 32-3.
A kind of explosion-proof cap-rotating type gas automatic tester of the present invention, when using this detector, only need the lid shell 32-1 that will have explosive-proof sealed circle 32-4 to be nested with the upper end of detecting gas at needs, gas feeds rotating base 31 and enters in the detector body 1 by draft tube 2, thereby realizes the automatic detection of gas.
Be enlightenment with above-mentioned foundation desirable embodiment of the present invention, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
