Description
Technical field
The utility model relates to a kind of extension bar opium pipe, belongs to environmental monitoring technology field.
Background technology
In to pollution source in flue dust and flue gas environmental monitoring, wherein fume/smoke monitor is often used by environmental monitoring mechanism.Fume/smoke monitor is mainly to the sampling of the dynamic pressure of flue, static pressure, flue-gas temperature, water capacity, oxygen level, gaseous contaminant (as: SO2, CO, CO2 etc.) measurement of concetration and particulate pollutant.But current existing sampling gun is in measuring process, most sampling pipe is all fixing specification, and dismounting is got up inconvenience, when sampling, need long whole-sample pipe, inefficiency in the wild simultaneously, complicated operation is loaded down with trivial details, brings very large inconvenience to sampling work.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of extension bar opium pipe, can according to the needs of sampling, and the method selecting suitable sampling extension bar to coordinate with sampling head is sampled, have employed sealing gasket to be effectively tightly connected simultaneously, ensure that the precision of sampling.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of extension bar opium pipe, comprise extension bar, extension bar sealing connecting component, sampling component and opium pipe handle, described sampling component is placed in extension bar opium pipe one end, sampling component is connected with extension bar sealing connecting component, and described opium pipe handle is placed in the extension bar opium pipe other end, it is characterized in that: described extension bar sealing connecting component comprises protection tube, flue dust pipe, recessed plug, attaching nut, convex plug; Described protection tube is placed in outermost, and flue dust pipe abuts against inside protection tube; Described recessed plug, convex plug are placed in two parts that extension bar connects seal assembly respectively, are equipped with spring contact and stationary contact respectively in described recessed plug, convex plug side.
Described recessed plug, convex plug are fixedly connected with by attaching nut.
Described recessed plug is built-in with sealing gasket.
Described sampling component comprises gland, inner sleeve, catch tray, nonreturn valve core, pressing handle and clevis arm; Described gland is placed in the open side of sampling component, and inner sleeve abuts against inside gland; Described catch tray is placed between inner sleeve, vertically with inner sleeve arranges, and described nonreturn valve core is placed in catch tray; Described pressing handle is placed in the rear side of sampling component, itself and clevis arm active link.
Described gland is connected with inner sleeve interference.
The beneficial effects of the utility model are, because the utility model can according to different sampling situations, select sampling extension bar suitable with it, meet sampling request, extension bar of simultaneously sampling is easy to dismounting, and after dismounting, entire length is short, is easy to carry, have employed the technological means arranging sealing gasket in recessed plug simultaneously, convex plug is pressed in recessed plug, sealing gasket is crushed out of shape sealing.Stationary contact and spring contact are close together under the pressure of convex plug, and the spring in spring contact is compressed, thus integral sealing links together.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in more detail;
The structural representation of extension bar opium pipe in Fig. 1 the utility model;
Fig. 2 is the cross-sectional schematic of the utility model extension bar sealing connecting component;
Fig. 3 is the cross-sectional schematic of the utility model sampling component;
Fig. 4 is the vertical view of the utility model sampling component.
Embodiment
As shown in Figure 1,2,3, 4, extension bar opium pipe in the utility model comprises extension bar 1, extension bar sealing connecting component 2, sampling component 3 and opium pipe handle 4, described sampling component 3 is placed in extension bar opium pipe one end, sampling component 3 is connected with extension bar sealing connecting component 2, described opium pipe handle is put 4 and is placed in the extension bar opium pipe other end, it is characterized in that: described extension bar sealing connecting component 2 comprises protection tube 21, flue dust pipe 22, recessed plug 23, attaching nut 24, convex plug 25; Described protection tube 21 is placed in outermost, and flue dust pipe 22 abuts against inside protection tube 21; Described recessed plug 23, convex plug 25 are placed in two parts that extension bar connects seal assembly 2 respectively, are equipped with spring contact 26 and stationary contact 27 respectively in described recessed plug 23, convex plug 25 side.Described recessed plug 23, convex plug 25 are fixedly connected with by attaching nut 24.Described recessed plug 23 is built-in with sealing gasket 28.Described sampling component 3 comprises gland 31, inner sleeve 32, catch tray 33, nonreturn valve core 34, pressing handle 35 and clevis arm 36; Described gland 31 is placed in the open side of sampling component 3, and inner sleeve 32 abuts against inside gland 31; Described catch tray 33 is placed between inner sleeve 32, vertically with inner sleeve 32 arranges, and described nonreturn valve core 34 is placed in catch tray 33; Described pressing handle 35 is placed in the rear side of sampling component 3, itself and clevis arm 36 active link.Described gland 31 is connected with inner sleeve 32 interference.
Extension bar opium pipe of the present utility model, can according to different sampling requests when sampling, and sampling head combines from different extension bars, can form 1M, the sampling pipe of 1.5M, 2M, 2.5M tetra-kinds of scale lengths, extension bar of simultaneously sampling is easy to dismounting, and after dismounting, entire length is short, is easy to carry.Protection tube 21 of the present utility model, flue dust pipe 22, recessed plug 23 are integrally welded, and attaching nut 24 can rotate on protection tube 21, and sealing gasket 28 is arranged in recessed plug 23; The other end of extension bar 2, convex plug 25 welds together with protection tube 21, flue dust pipe 22, sealing after welding; During connection, left and right figure combines, and screws attaching nut 24 and makes convex plug 25 be pressed in recessed plug 23, and sealing gasket 28 is crushed out of shape sealing.Stationary contact 27 and spring contact 26 are close together under the pressure of convex plug 25, and the spring in spring contact 26 is compressed, thus integral sealing links together.
Be that interference links into an integrated entity between sampling component 3 gland 31 of the present utility model and inner sleeve 32, can move forward and backward in catch tray 33.When rotatably compressing handle 35, driving clevis arm 36 to seesaw by the bias of pressing handle 35 self, compressing gland 31 and inner sleeve 32, play the effect of fixing seal sampling head.The nonreturn valve core 34 of the utility model in catch tray 33, the sealed cavity formed is little, when sample gas suck-back, nonreturn valve core 34 action, block catch tray 33 mouthfuls because between cavity little, gas expanding volume when suck-back is also little, anti-suck effect is put into after sampling pipe more than retaining valve, or good many in instrument.Surface treatment of the present utility model is simultaneously that entirety carries out vapour deposition titanium coating, and rust-proof effect significantly promotes, and after multiple repairing weld, does not have corrosion phenomenon, improves serviceable life significantly.
