Utility model content
The purpose of this utility model is just to provide a kind of water quality monitoring fluid sample conveying device, and to solve, water sample transfer pipeline between sampled point and monitoring equipment is long to be caused dead volume excessive and make the problem of sampling distortion.
The utility model is achieved in that a kind of water quality monitoring fluid sample conveying device, includes:
Two-bit triplet solenoid valve, its valve body is provided with first input end mouth, the second input port and output port, described first input end mouth is used for connecting Quality Control instrument by pipeline, think that monitoring equipment provides the standard water sample provided by Quality Control instrument, described second input port is used for connecting water sampling point by pipeline, thinks that monitoring equipment provides detection water sample;
Threeway, its body is provided with the first port, the second port and the 3rd port, described first port is connected by pipeline with the described output port of described two-bit triplet solenoid valve, described second port is used for connecting monitoring equipment nearby by pipeline, think monitoring equipment transfer criteria water sample or detect water sample, described 3rd port connects discharge pipe line; And
Liquid transfer power source, is connected in described discharge pipe line, for being discharged by the water in pipeline, and to monitoring equipment transfer criteria water sample or detection water sample.
The utility model also includes:
Housing, splendid attire is also fixedly connected with two-bit triplet solenoid valve, threeway and Liquid transfer power source, have four interfaces on the housing, first interface is wherein the connector of the described first input end mouth of described two-bit triplet solenoid valve, second interface is the connector of described second input port of described two-bit triplet solenoid valve, 3rd interface is the connector of described discharge pipe line, and the 4th interface is the connector of described second port of described threeway.
Described Liquid transfer power source in the utility model is the one in peristaltic pump, syringe pump, traction pump or turbopump.
The utility model is arranged on Quality Control instrument, between water sampling point and monitoring equipment, by the control to two-bit triplet solenoid valve, achieves the conveying to monitoring equipment of Quality Control the instrument standard water sample exported and the detection water sample gathered from water sampling point and switch; By the control to Liquid transfer power source, standard water sample and detection water sample can be realized to carry to the active of monitoring equipment, and to the timely cleaning of water sample transfer pipeline with by the timely discharge of waste liquid.Even more important is a bit, the utility model is as an auxiliary equipment, the side of monitoring equipment can be arranged on nearby, by two-bit triplet solenoid valve, work between threeway with Liquid transfer power source coordinates, after by the retention water sample cleaning in water sample transfer pipeline, the standard water sample of renewal and the detection water sample of renewal can be sent to monitoring equipment is contiguous, be equivalent to the collection nearby carrying out detecting water sample water sampling point having been extended to monitoring equipment, overcome the hard nut to crack that this water quality monitoring industry of sampling distortion is difficult to overcome for a long time thus, ensure that the validity and reliability of Monitoring Data.Key of the present utility model is just this.
The utility model can realize detecting the conveying of the standard water sample that water sample or Quality Control instrument provide, emptying and rinse, improve liquid delivery rate and reliability, solve the problem of the sampling distortion excessive caused because of the stagnant water volume that transfer pipeline is long or retain in pipeline between water sampling point and monitoring equipment.
