Abstract
The utility model provides a convenient and effective water sampler, which comprises a hollow long cylindrical pipe body (3); a top component (2) fixed on the top of the cylindrical pipe body (3); a bottom component (4) fixed on the bottom of the cylindrical pipe body (3); and a flow rate control nozzle (8) connected with the bottom component (4) in a separable manner.
Description
Technical field
The utility model relates to the required water-quality sampler of environmental engineering monitoring.
Background technology
Water-quality sampler mainly is used to gather underground water or waste water, the especially water sample of the deep well that some bores are little.Common water-quality sampler is mainly by hollow elongated cylinder pipe shaft, and ball valve made of plastic and ball valve base are formed.When sampler was slowly transferred in the well, ball valve made of plastic rose owing to being subjected to buoyancy of water, thereby watery stool enters sampler by valve.After obtaining suitable water sample, sampler is slowly sling, and at this moment ball valve again can the pressure of water drops on the ball valve base in the pipe shaft because of being subjected to, thus closed sampling thief, and the water sample that prevention obtains runs off.This sampling thief simplicity of design, easy to use, but also have some problems.Ball valve made of plastic is the critical component of whole sampler, finish sealing function after the sampling by it, but its position in whole pipe shaft is extremely fixing, falls back in the process of ball valve base at it, can cause the loss of a large amount of water samples.And ball valve only is because the pressure of water falls after rise on base, and is probably poorly sealed, thereby water sample is run off.It is also very inconvenient to take out water sample from this water-quality sampler.Because the ball valve closure, the collecting work person need disclose out ball valve with thin rod, allows water sample flow out.So just can't be according to the size of how much coming controlled water flow of required water sample.
Therefore,, need a kind of water sample of can more effectively avoiding to run off, more can conveniently discharge water sample in view of the problem that exists in the aforementioned existing design, and the valve design of energy adjustment release speed.
The utility model content
For realizing above-mentioned target, the utility model provides a kind of more convenient effective water-quality sampler, and it comprises: hollow elongated cylinder pipe shaft, be fixed in the upper end of described right cylinder pipe shaft tip part, be fixed in described right cylinder pipe shaft the lower end bottom end member and be connected flow control nozzle on the described bottom end member separably.
The diameter of described bottom end member diminishes from the top down gradually, and after forming a step, diameter slightly increases, and, described bottom end member comprises the cone-shaped body spool, and there are many legs the lower end of spool, and the leg end is the structure of outwards stretching out with the right angle, make when spool moves up, can't be by the step of bottom end member.Sampling thief is in the process of transferring, and spool can rise because of buoyancy of water, but the amplitude that rises has been subjected to control, and when spool falls after rise, can be faster more closed.And O shape circle 7 is equipped with at cone-shaped body spool middle part, when guaranteeing that spool is closed sealing tight, thereby more effectively avoid the loss of water sample.
The outside of part is formed with external thread below the leaning on than step of described bottom end member, on the inwall of described flow control nozzle, be formed with internal thread, and described flow control nozzle is provided with interior ring in inside, when described flow control nozzle was threadingly engaged on the bottom end member, ring promoted the right angle legs end rising of spool in this.Thereby spool also rises gradually, and watery stool can flow out from the bottom outlet.Simultaneously, by the degree that adjusting is threaded into, controlled water flow speed discharges an amount of water sample at an easy rate.
Description of drawings
Fig. 1 is the in-built cut-open view of expression water-quality sampler.
Fig. 2 (a) is the stereographic map of expression spool and O shape circle, and Fig. 2 (b) is the stereographic map of expression bottom end member, and Fig. 2 (c) is the stereographic map of expression flow control nozzle.
Embodiment
Fig. 1 has showed the internal structure of water-quality sampler, and it is by hollow elongated cylinder pipe shaft 3, tip part 2, and bottom end member 4 and separable flow control nozzle 8 are formed.
Tip part 2 is fixed in the upper end of right cylinder pipe shaft 3, and the trapezoidal hole 13 of this tip part can be so that current freely pass through right cylinder pipe shaft 3.Tip part 2 is an annulus topmost, can be used to connect with rope, so that water-quality sampler is transferred or mentioned.
Spool 6 is a cone-shaped body, and O shape circle 7 is equipped with at its middle part, and sealing is tight when guaranteeing that spool 6 is closed.There are many (being four in the present embodiment) legs the bottom of cone-shaped body, and leg end 9 is the structures of outwards stretching out with the right angle, thereby, when spool 6 moves up, the step butt of leg end 9 and bottom end member 4, and make spool 6 can't pass through this step.There is external thread the outside of hollow tubular 12, can be used for installing metal and add heavy parts or link to each other with the flow control nozzle.
When inwall 11 was threadingly engaged on the bottom end member 4 for screw-shaped flow control nozzle 8, the right angle legs end 9 that interior ring 10 will promote spool 6 rose gradually, thereby spool also rises gradually, and watery stool can export 5 from the bottom and flow out.
Claims (3)
1. water-quality sampler comprises:
1) hollow elongated cylinder pipe shaft (3);
2) be fixed in the tip part (2) of the upper end of described right cylinder pipe shaft (3);
