Abstract
Helix tube type urea sensor firm banking, comprise firm banking body, the edge of firm banking body is provided with inhales urea tube via hole, firm banking body edges is also provided with outward extending spiral positioning edge, firm banking body central is provided with electron tube base and fixes via hole, and firm banking body is also provided with screen pack hole clipping.Use the utility model, screen pack back-off snaps in screen pack hole clipping, and screen pack is fixed; Clamp for spiral pipe is combined on the spiral positioning edge of firm banking body edges, prevents electron tube from rotating and loosens.
Description
Technical field
The utility model relates to a kind of helix tube type urea sensor firm banking.
Background technology
Urea in urea box is extracted out by volume pump by inhaling urea tube by urea sensor, in urea box, urea needs net filtration impurity after filtration, the urea of such ejection can better react with tail gas, also impurity can be avoided to block pipeline, thus need bottom urea sensor, inhale urea tube top install screen pack.Like this, in sensor base, just need a screen pack fixing device for installing, can be fixed stainless steel electron tube, to ensure the accuracy of liquid level gauging simultaneously.
Prior art adopts base mode to fix screen pack: be directly inserted in by screen pack and inhale on urea tube, and screen pack is fixing firm not; Fixing also firm not between electron tube and base, easily rotate between electron tube and base and loosen.
Utility model content
Technical problem to be solved in the utility model is, overcomes the deficiency of above-mentioned background technology, provides a kind of fixed helix tube type urea sensor firm banking.
The technical scheme that the utility model solves the employing of its technical matters is, a kind of helix tube type urea sensor firm banking, comprise firm banking body, the edge of described firm banking body is provided with inhales urea tube via hole, described firm banking body edges is also provided with outward extending spiral positioning edge, described firm banking body central is provided with electron tube base and fixes via hole, and described firm banking body is also provided with screen pack hole clipping.
Further, the upper surface of described firm banking body is also provided with floating drum buffering muscle.
Further, the quantity of described screen pack hole clipping is two.
Compared with prior art, advantage of the present utility model is as follows:
(1) firm banking body is provided with screen pack hole clipping, and screen pack back-off snaps in screen pack hole clipping, and screen pack is fixed.
(2) firm banking body edges also has outward extending spiral positioning edge, and clamp for spiral pipe is combined on the spiral positioning edge of firm banking body edges, prevents electron tube from rotating and loosens.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is vertical view embodiment illustrated in fig. 1.
Fig. 3 is upward view embodiment illustrated in fig. 1.
Fig. 4 is the scheme of installation of 1 illustrated embodiment and urea sensor, screen pack.
In figure: 1-inhale urea tube via hole, 2-spiral positioning edge, 3-screen pack hole clipping, 4-electron tube base fixes via hole, 5-floating drum buffering muscle, 6-spiral pipe, 7-electron tube, 8-electron tube base, 9-inhale urea tube, 10-firm banking body, 11-retainer nut, 12-screen pack, 13-floating drum.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 3, the present embodiment comprises firm banking body 10, the edge of firm banking body 10 is provided with inhales urea tube via hole 1, firm banking body 10 edge is also provided with outward extending spiral positioning edge 2, firm banking body 10 center is provided with electron tube base and fixes via hole 4, firm banking body 10 is also provided with two screen pack hole clippings 3.
With reference to Fig. 2, the upper surface of firm banking body 10 is also provided with floating drum buffering muscle 5.The Main Function of floating drum buffering muscle 5 is: allow the floating drum 13 of urea sensor form point cantact with firm banking body 10 surface, instead of face contact, prevents floating drum 13 and firm banking body 10 to be bonded together.
With reference to Fig. 4, the installation process of the utility model and urea sensor and screen pack is as follows:
1, bottom the electron tube 7 electron tube base 8 being soldered to urea sensor;
2, will be arranged on the utility model bottom urea sensor, the utility model is aimed at spiral pipe 6 bottom surface, coupling electron tube base 8 and suction urea tube 9 lower end position, urea sensor is snapped in the utility model, make bottom welding have the electron tube 7 of electron tube base 8 to insert electron tube base and fix via hole 4, suction urea tube 9 is inserted and inhales urea tube via hole 1, make spiral pipe 6 be fastened on the spiral positioning edge at firm banking body 10 edge;
3, pad and retainer nut 11 are locked on electron tube base 8 screw, lock is put down, lock;
4, screen pack 12 back-off is snapped in screen pack hole clipping 3 of the present utility model.
Screen pack 12 back-off snaps in screen pack hole clipping 3, and screen pack is fixed; Clamp for spiral pipe is combined on the spiral positioning edge of firm banking body edges, prevents electron tube from rotating and loosens.
Those skilled in the art can carry out various modifications and variations to the utility model embodiment; if these amendments and modification are within the scope of the utility model claim and equivalent technologies thereof, then these revise and modification also within protection domain of the present utility model.
The prior art that the content do not described in detail in instructions is known to the skilled person.
