Abstract
The utility model relates to a sampler which takes out liquid from a high-pressure pipeline and a high-pressure container to be served as a sample. The outlet of a master valve is connected with a tee joint, the other end of the tee joint is connected with a sampling valve and a bent pipe, and another end of the tee joint is connected with a liquid storage container and an emptying valve. The sampler has the advantages of compact structure, favorable sealing performance, light weight, long service life, convenient and reliable sampling, and no environment pollution.
Description
A kind of sampler, it is to be applicable to the device that takes out pressure duct from media such as conveying or oil in reserve, water, nitrose liquid or polyacrylamides, the high pressure vessel as the liquid of sample.
Before the sampler that the utility model provides is come out, from pressure duct or high pressure vessel, take out as the liquid of sample very difficult.Sampling is pipeline of welding on pipeline or container normally, valve in the other end attaching of this pipeline.During sampling, owing to pipeline, container inner pressure height, in a single day sample cock is opened, and the liquid of desire sampling erupts as the volcano, can't collect.This sampling method was both wasted, again contaminated environment.
The purpose of this utility model provides and a kind ofly takes a sample conveniently, safe and reliable sampler again.
The purpose of this utility model is achieved in that a tee pipe coupling in this sampler, one end of pipe adapter is connected with total valve and taper-thread head, the taper-thread of taper-thread head is connected with pressure piping or high pressure vessel, the other end of tee pipe coupling is connected with sample cock and bend pipe, and the another end of tee pipe coupling is connected with liquid storage container and emptying valve; The emptying valve is an external thread stop valve, and total valve and sample cock are the soft sealing ball valves (number of patent application 93227340.8) of same model, and liquid storage container is two all threaded column type pressure vessels of end socket up and down.When sample cock and emptying valve are in closed condition, open total valve, sampling liquid is flowed in the liquid storage container, slowly open the emptying valve again, air is drained.Close emptying valve and total valve then, open sample cock, just can take a sample.
The sampler that the utility model provides, compact conformation, good airproof performance, in light weight, long service life takes sample both convenient, safe and reliable, free from environmental pollution again.
In conjunction with the accompanying drawings, again detailed structure of the present utility model is described below:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the emptying valve in the utility model.
As can be seen from Figure 1, sampler comprises emptying valve 1, liquid storage container 2, total valve 3, taper-thread head 4, sample cock 5, tee pipe coupling 6, bend pipe 7, one end of tee pipe coupling 6 is connected with total valve 3 and taper-thread head 4, screw thread on the taper-thread head 6 is connected with pressure piping or high pressure vessel, the other end of tee pipe coupling 6 is connected with sample cock 5 and bend pipe 7, and the another end of tee pipe coupling 6 is connected with liquid storage container 2 and emptying valve 1.
As can be seen from Figure 2, in the emptying valve 1 of sampler, connecting thread is produced at the two ends, the left and right sides of valve body 1-1, after the end of valve rod 1-3 links to each other with flap 1-2, the valve rod 1-3 that has flap 1-2, filler 1-7, stem nut 1-5 and nut 1-6 are installed in the cavity volume of valve body 1-1 successively, the other end of valve rod 1-3 links to each other with handwheel 1-4 again.
From Fig. 1, it can also be seen that, liquid storage container 2 is made up of upper cover 2-1, low head 2-2 and cylindrical tube 2-3, internal thread is produced in the end of upper cover 2-1, and external thread is produced in the end of low head 2-2, and upper and lower two end socket 2-1,2-2 and cylindrical tube 2-3 are integrally welded.
Use the sampling process of this sampler to be: close sample cock 5 and emptying valve 1 earlier, open total valve 3, sampling liquid is flowed in the liquid storage container 2, will slowly open emptying valve 1 this moment, and the air in the liquid storage container 2 is bled off.Emptying speed should be determined by the shear rate restriction of being got liquid.For example: the emptying speed of the polyacrylamide solution of light 5000 mg/litre of concentration should be greater than 368 ml/min.The emptying amount should be greater than the total measurement (volume) of liquid storage container 2.After finishing said procedure, close emptying valve 1, make the sampling liquid stabilising in liquid storage container 2, close total valve 3 again, cut off the liquid that leads to liquid storage container 2.Subsequently, open emptying valve 1 earlier, open sample cock 5 again, sampling.
Sampling finishes, and remaining liq in the sampler is all drained, and closes all valves then, in order to avoid conjunctiva after the remaining liquid dried, influences the usability of whole device.In addition, this sampler should regularly be cleaned inside.
Claims (3)
1, a kind of sampler, it comprises that the total valve, the endpiece that are connected with pressure piping or high pressure vessel are connected three-way pipe, it is characterized in that: the other end of tee pipe coupling is connected with sample cock and bend pipe, and the another end of tee pipe coupling is connected with liquid storage container and emptying valve.
2, sampler according to claim 1, it is characterized in that: there is connecting thread at the left and right two ends of the valve body of emptying valve, after one end of valve rod links to each other with flap, valve rod, filler, stem nut and the nut that again an end is had a flap is installed in the cavity volume of valve body successively, and the other end of valve rod links to each other with handwheel.
3, sampler according to claim 1 is characterized in that: liquid storage container is made up of upper and lower two end sockets and cylindrical tube, and the end of upper cover is an internal thread, and the end of low head is an external thread, and upper and lower two end sockets and cylindrical tube are integrally welded.
