Abstract
The invention discloses a spiral tube-type fixed base for a urea sensor. The fixed base comprises a fixed base body; an urea suction tube via hole is formed in the edge of the fixed base body; the edge of the fixed base body is also provided with spiral positioning clamping edges extending outwards; an electron tube base fixing via hole is formed in the center of the fixed base body; filter screen clamping holes are also formed in the fixed base body. By using the spiral tube-type fixed base disclosed by the invention, a filter screen is reversely clamped into the filter screen clamping holes, so that the filter screen can be fixed firmly; a spiral tube is clamped on the spiral positioning clamping edges of the edge of the fixed base body, so that the spiral tube is prevented from rotating and getting loose.
Description
Technical field
The present invention relates to a kind of helix tube type urea sensor firm banking.
Background technology
By inhaling urea tube by the urea in urea box by measuring pumped, urea needs Jing to urea sensor in urea box
Filter screen filtration impurity, the urea for so spraying preferably can react with tail gas, it is also possible to avoid impurity from blocking pipeline, therefore need
In urea sensor bottom, inhale urea tube top installation screen pack.So, in sensor base, it is necessary to a screen pack peace
Dress fixing device, while stainless steel electron tube can be fixed, to ensure the degree of accuracy of liquid level gauging.
Prior art is to fix screen pack using base mode：Directly screen pack is inserted on suction urea tube, screen pack is solid
It is fixed not firm enough；Fixation is also not firm enough between electron tube and base, and easily rotation loosens between electron tube and base.
The content of the invention
The technical problem to be solved is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of fixed
Helix tube type urea sensor firm banking.
The present invention solves the technical scheme of its technical problem employing, a kind of helix tube type urea sensor firm banking,
Including firm banking body, the edge of the firm banking body is provided with suction urea tube via, the firm banking body edges
The spiral positioning edge for stretching out is additionally provided with, the firm banking body central is provided with electron tube base and fixes via, described
Screen pack hole clipping is additionally provided with firm banking body.
Further, the upper surface of the firm banking body is additionally provided with floating drum buffering muscle.
Further, the quantity of the screen pack hole clipping is two.
Compared with prior art, advantages of the present invention is as follows：
（1）Firm banking body is provided with screen pack hole clipping, and screen pack back-off is snapped in screen pack hole clipping, and screen pack is fixed
It is firm.
（2）Firm banking body edges also have the spiral positioning edge for stretching out, and helix tube is fastened on firm banking sheet
On the spiral positioning edge at body edge, prevent electron tube rotation from loosening.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
With reference to Fig. 1, Fig. 3, the present embodiment includes firm banking body 10, and the edge of firm banking body 10 is provided with suction urea
Pipe via 1, the edge of firm banking body 10 is additionally provided with the spiral positioning edge 2 for stretching out, and the center of firm banking body 10 sets
There is electron tube base to fix via 4, two screen pack hole clippings 3 are additionally provided with firm banking body 10.
With reference to Fig. 2, the upper surface of firm banking body 10 is additionally provided with floating drum buffering muscle 5.Floating drum buffers the Main Function of muscle 5
It is：Allow the floating drum 13 of urea sensor and the surface of firm banking body 10 to form point to contact, rather than face contacts, and prevents floating drum 13
It is bonded together with firm banking body 10.
With reference to Fig. 4, the present invention is as follows with the installation process of urea sensor and screen pack：
The 1st, electron tube base 8 is soldered to the bottom of electron tube 7 of urea sensor；
2nd, urea sensor bottom is arranged in the present invention, by present invention alignment helix tube 6 bottom surface, matching electron tube bottom
Seat 8 and the suction lower end position of urea tube 9, urea sensor is snapped in the present invention, makes bottom welding have the electronics of electron tube base 8
The insertion electron tube base of pipe 7 fixes via 4, makes the insertion of suction urea tube 9 inhale urea tube via 1, makes helix tube 6 be fastened on fixed bottom
On the spiral positioning edge at seat body 10 edge；
3rd, pad and stop nut 11 are locked on the screw of electron tube base 8, lock is flat, locking；
During the 4th, the back-off of screen pack 12 to be snapped in the screen pack hole clipping 3 of the present invention.
The back-off of screen pack 12 is snapped in screen pack hole clipping 3, and screen pack is fixed；Helix tube is fastened on firm banking body
On the spiral positioning edge at edge, prevent electron tube rotation from loosening.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these modifications and change
Within the scope of the claims in the present invention and its equivalent technologies, then these modifications and modification are also in protection scope of the present invention for type
Within.
The prior art that the content not described in detail in specification is known to the skilled person.
