Mouthful, described elastic head puts to be provided with when being contracted to critical value with elastic headgear and closed, when extending into critical value with elastic headgear
It is additionally provided with the through hole of insertion, the body for solution flows backwards from inlet in obstructing tube body piston.
After above structure, the of the invention liquid flowing tube for being used for bath trough on plating line have compared with prior art with
Lower advantage：First, when the lower end of body is stretched into below liquid level, the high pressure of liquid drives the elastic headgear of evagination state to shrink, by
This through hole for putting elastic head is gradually reduced to closure state, and the obturation effect for raising through hole with hydraulic pressure is more preferable, and is worked as
When reaching set depth, elastic headgear is compressed into the extreme position of horizontality, and instant reverse is into concave shape, now
The through hole that elastic head is put is opened, and is more than the aperture of evagination state through hole in the aperture of higher hydraulic pressure effect lower through-hole,
Thus the sampling for the set depth region in bath trough is completed, body upper end is closed without testing staff in the process
The mouth of pipe, therefore operation is easier, secondly, when flowing into enough sampling liquid in body, body is extracted, in gravity and body
The pressure lower piston closure inlet of interior liquid, completion takes liquid, blocks the step of body upper end open with finger without operating personnel
Suddenly, therefore, sampling process is easier to be reliable.
The position of the nearly inlet of body is the up big and down small pyramidal structure of caliber, and the piston is the taper with body

When can need tapping after the liquid flowing tube of the present invention is placed in laboratory, piston is adsorbed by magnetic patch, drives piston stroking upward to complete to put
Liquid, so as to avoid the influence of the human hand grease that is brought from body upper end open pouring liquid for testing result.
Further, described overcoat is elastic rubber layer.
When the elastic headgear indent, the lower surface of elastic headgear upper end vertically and piston leans, and
Drive piston stroking upward.In body enter liquid before, piston under self gravitation effect all the time be in tenesmus state, and with cone
The inside pipe wall laminating of shape, now when elastic headgear is overturn by external water pressure in concave configuration, due to the blocking of piston, makes
Tube cavity between piston and elastic headgear is in certain high pressure conditions, has obstructed environmental liquids and has entered in pipe.And pass through elasticity
During headgear indent with piston against and when driving one segment distance of piston stroking upward, the tapered sidewalls of the piston depart from inside pipe wall to be pasted
Conjunction state, thus connects the cavity corresponding to piston upper and lower end face, eliminates high pressure conditions, so as to be conducive to liquid smoothly from logical
Enter in hole in body.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As illustrated, the present invention provides a kind of liquid flowing tube for bath trough on plating line, it includes the pipe of two ends insertion
Body 1, the inlet 1.1 of the lower end of body 1 is provided with original state evagination, when the inlet of the lower end of body 1 stretches to set depth
When elastic headgear 2 deform the elastic headgear 2 of indent, elastic headgear 2 is fixed with the lower end of body 1 and covers inlet 1.1, described
Elastic headgear 2 is closed when being provided with elastic 2 evagination of headgear, with the through hole 2.1 of insertion during elastic 2 indent of headgear, the body 1
Inside it is additionally provided with for obstructing the piston 3 that solution flows backwards from inlet 1.1 in body 1.
Above-mentioned set depth refers to, because the lower end of body 1 is immersed in plating solution, therefore the inside and outside formation pressure difference of body, and
The size calculation formula for the pressure values being subject on elastic headgear 2 is P=ρ gh, and wherein P is pressure values, and ρ is plating solution density, and g attaches most importance to
Power acceleration, h is immersion depth, and elastic headgear 2 can be by elastic headgear 2 from evagination state deformation to concave configuration
The coefficient of elasticity of structure and material is designed, so that the setting pressure values of the elastic deformation of headgear 2 are obtained, and this sets
