Abstract
The utility model discloses a liquid sampling device with a connecting rod. The liquid sampling device comprises a sampling pipe, an upper valve, a lower valve and an outer connecting rod, wherein the sampling pipe is a hollow pipe, the upper aperture and the lower aperture of which are consistent, the upper valve and the lower valve are correspondingly arranged at the upper end and the lower end of the sampling pipe; a handle is arranged at one end of the outer connecting rod; and the outer connecting rod is connected between external handles of the upper valve and the lower valve so as to realize the linkage of the upper valve and the lower valve. The liquid sampling device with the connecting rod, disclosed by the utility model, can be used for efficiently and accurately sampling liquid in great depth.
Description
Technical field
The utility model relates to a kind of for the utensil on the energy, chemical industry, is specifically related to a kind of connecting rod liquid sampler.
Background technology
In industrial chemicals production run, many times need the liquid of the large degree of depth to sample, for example: storage tank and oil drum.In order to ensure the homogeneity of sampling, generally need to carry out total cross-section sampling, to obtaining the fluid column identical with liquid every aspect character.And at present, for the total cross-section sampler of this large degree of depth liquid, the main stopple coupon that adopts bottom reducing, completes after sampling, with weight shutoff bottom feed mouth, take out after stopple coupon, reintroduce weight, the fluid column of acquisition is put into sampling jar.
While adopting this old-fashioned stopple coupon, there will be several problems: 1. because the external diameter of weight and the internal diameter difference of stopple coupon that adopt are less, the solid impurity in liquid easily causes sampling inhomogeneous; 2. during with weight shutoff bottom feed mouth, be vulnerable to the interference of liquid bottom impurity, cause bottom feed mouth not seal completely, while proposing stopple coupon, be easy to produce and leak; 3. weight need to use longer connecting line, and in sampling process, this root connecting line is immersed in the liquid in stopple coupon always, and in use procedure, strength of joint can reduce very soon.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and a kind of connecting rod liquid sampler is provided, and it can be more efficiently, carry out more accurately the sampling of large degree of depth liquid.
The purpose of this utility model is achieved in that a kind of connecting rod liquid sampler, comprises stopple coupon, upper and lower valve and outside connecting rod, wherein,
Described stopple coupon is the consistent hollow tubular of bore Shang Xia;
Described upper and lower valve is arranged on the upper and lower end of described stopple coupon correspondingly;
Described outside connecting rod is connected between the outer handle of described upper and lower valve, to realize the interlock of described upper and lower valve.
Above-mentioned connecting rod liquid sampler, wherein, described stopple coupon is that diameter is hollow steel pipe or the plastic tube of 1 cun.
Above-mentioned connecting rod liquid sampler, wherein, described outside connecting rod is connected with the outer handle of described upper and lower valve by pin.
Above-mentioned connecting rod liquid sampler, wherein, described upper and lower valve is ball valve.
The technical scheme of connecting rod liquid sampler of the present utility model, stopple coupon adopts the consistent hollow steel pipe of upper and lower bore or plastic tube, can not be subject to the interference of solid impurity in liquid, and respectively connect a valve at the upper and lower end of stopple coupon, upper and lower valve connects by outside connecting rod, can realize interlock, the liquid in stopple coupon can not be flowed out, can prevent from revealing generation.Connecting rod liquid sampler of the present utility model can be more efficiently, carry out more accurately the sampling of large degree of depth liquid.
Brief description of the drawings
Fig. 1 is the structural representation of connecting rod liquid sampler of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, a kind of connecting rod liquid sampler of the present utility model, comprises stopple coupon 1, upper and lower valve 2,3 and outside connecting rod 4, wherein:,
Stopple coupon 1 is the consistent hollow tubular of bore Shang Xia; It is hollow steel pipe or the plastic tube of 1 cun that stopple coupon 1 can adopt diameter;
Upper and lower valve 2,3 is arranged on the upper and lower end of stopple coupon 1 correspondingly; Upper and lower valve 2,3 can adopt ball valve;
One end of outside connecting rod 4 is with handle 40, and this outside connecting rod 4 is connected between the outer handle of upper and lower valve 2,3 by pin 20,30 respectively, to realize the interlock of upper and lower valve 2,3.
The course of work of connecting rod liquid sampler of the present utility model is: first upper and lower valve 2,3 is all opened, then stopple coupon 1 is vertically put into liquid lentamente, arrive after liquid bottom until the lower end of stopple coupon 1, now in stopple coupon, fill sampling liquid, closed and closed valve 2 by the handle 40 on outside connecting rod 4 again, now lower valve 3 also can be closed simultaneously; Then after stopple coupon 1 is taken out from liquid, then open lower valve 3 by the handle 40 on outside connecting rod 4, the liquid in stopple coupon 1 is put into sampling jar, complete sampling work, finally stopple coupon 1 is cleaned and wiped clean, wait until and use next time.
Connecting rod liquid sampler of the present utility model can be more efficiently, carry out more accurately the sampling of large degree of depth liquid, the interference of solid impurity can not be subject to liquid in whole sampling process in, because the upper and lower end of stopple coupon is separately installed with the good valve of closed performance, therefore in the time proposing stopple coupon, can not produce leakage.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
