Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises a measuring device 1 and for supporting the iron stand 2 of measuring device 1.Measuring device 1 comprises large diameter measurement section 11 in being wholely set and minor diameter measuring section 12, and wherein, large diameter measurement section 11 and minor diameter measuring section 12 to be arranged and inside is communicated with in coaxial.On the end of minor diameter measuring section 12 is imported and exported, be provided with one first cock 3, on the end of large diameter measurement section 11 is imported and exported, be provided with one second cock 4.First cock 3 adopts the cock with a vertical through hole in prior art; Second cock 4, on the basis arranging vertical through hole, sets up an oblique perforate be communicated with vertical through hole, and in oblique perforate, insert a piston 5 (as shown in Figure 3).
In above-described embodiment, as shown in Figure 1, measuring device 1 can with reduced diameter section 12 upper, enlarged diameter section 11 under mode vertical support on iron stand 2, and place a graduated cylinder 6 at the iron stand 2 be positioned at below measuring device 1, set-up mode is now applicable in fluid to be batched, the situation (hereafter will describe in detail) that the fluid density that flow is little is also less.
In above-described embodiment, as shown in Figure 2, measuring device 1 also can with enlarged diameter section 11 upper, reduced diameter section 12 under mode vertical support on iron stand 2, the oblique through hole of the second cock 4 is the direction placement of lower-left upper right, and on the iron stand 2 being positioned at enlarged diameter section 11 side, support a graduated cylinder 6, the opening of graduated cylinder 6 exports relative with the oblique through hole of the second cock 4, set-up mode is now applicable in fluid to be batched, the situation (hereafter will describe in detail) that the fluid density that flow is little is larger.
In above-described embodiment, enlarged diameter section 11 and reduced diameter section 12 also can be processed respectively, are then tightly connected by rubber plug etc., and its advantage is to combine according to demand, but also there is the problem that difficulty of processing is large, cost is high, error increases.
In above-described embodiment, measuring device 1 can be made up of transparent material, and is carved with scale mark respectively on enlarged diameter section 11 and reduced diameter section 12, is convenient to the observation in experimentation.
In above-described embodiment, the first cock 3, second cock 4 and piston 5 are frosted plug.
The utility model in use, can be divided into two kinds of situations:
(1) situation one: the fluid density that flow is little is less.As shown in Figure 1, the reduced diameter section 12 of measuring device 1 is arranged on the top of enlarged diameter section 11 in use, need for keeping accurate measurement in enlarged diameter section 11, be full of that large one phase flow body of density in advance, then the first cock 3 is opened, two-phase fluid is imported and exported from the end of reduced diameter section 12 and is flowed into, and can start metering.When fluid will be full of reduced diameter section 12, open the second cock 4 (piston 5 in the second cock 4 is in sealing state), the fluid inflow cylinder 6 in metering, liquid level in reduced diameter section 12 declines, close the second cock 4 after stable, continue reading, so carry out subsequent experimental.
(2) situation two: the fluid density that flow is little is larger.As shown in Figure 2, the reduced diameter section 12 of measuring device 1 is arranged on the below of enlarged diameter section 11 in use.Close the first cock 3, open the second cock 4, two-phase fluid metering from the end of enlarged diameter section 11 is imported and exported after inflow.When two-phase fluid is full of measuring device 1, can pull out the piston 5 in the second cock 4, unnecessary fluid can flow into graduated cylinder 6, and experiment can proceed.If graduated cylinder 6 is not easily placed, also can pass through the afterbody connection rubber tube in the second cock 4 and extend to groove 7 place, the other one section of access graduated cylinder 6 of rubber tube.If the fluid that density is larger is full of reduced diameter section 12, then open the first cock, release a part of fluid to (should be the graduated cylinder that precision is higher) in graduated cylinder, treat the follow-up number of resuming studies of liquid level stabilizing, so carry out subsequent experimental.
Utilize the utility model, the maximum volume of quantifiable low discharge fluid is the volume sum of large diameter measurement section 11 and minor diameter measuring section 12, all meterings within the scope of this, all by regulating the first cock 3 or the second cock 4 to realize, the volume of the phase that flow is large can carry out submeter by external graduated cylinder 6.
The utility model is only described with above-described embodiment, and the structure of each parts, setting position and connection thereof all can change to some extent.On the basis of technical solutions of the utility model, all improvement of carrying out individual part according to utility model principle of the present utility model or equivalents, all should not get rid of outside protection domain of the present utility model.
