A kind of water treatment agent throwing device
Technical field
The utility model relates to water treating equipment, is specifically related to a kind of water treatment agent throwing device.
Background technology
Adding medicament to water body has dry type to add method and wet type adds two kinds of methods.The dry type method of adding refers to directly medicament be added to water body by artificial or mechanical means.The wet type method of adding is earlier medicament to be made into certain density solution, is adding to water body by mechanical means then.The medicament good uniformity that adopts the wet type method of adding to add, medicament can not fly upward with the wind, and is better to environment; But wet type adds method often exists defective in metering, can accurately not add.
Existing water treatment agent throwing device is made up of volume pump, safety valve, back pressure valve, deoscillator and supporting system of pipe and valve thereof.Have the following disadvantages in the use: manual shift dosage, volume pump can only regulating frequency and strokes, come analog measurement, and error is bigger, and can not accurately show; Whether being added a ductwork pressure influences greatly, and dosage changes at any time, can not intuitively demonstrate soup and enter into and add pipe network.
Summary of the invention
The utility model purpose is the deficiency that exists at prior art, and a kind of water treatment agent throwing device is provided, and it is accurate measurement, intuitive display not only, and easy and simple to handle.
The technical solution of the utility model is as follows:
A kind of water treatment agent throwing device, comprise base, be located at the force (forcing) pump on the base, it is characterized in that: also comprise a synthetic glass ejector, can observe directly the flow state of soup, one entrance of described synthetic glass ejector links to each other through rising pipe with described pressurization delivery side of pump, and the input terminus of described force (forcing) pump links to each other with a water inlet pipe, and described water inlet pipe is provided with a valve; Another entrance of described synthetic glass ejector links to each other with a pipette, and described pipette is provided with under meter; The outlet of described synthetic glass ejector links to each other with an end of a vacuum breaker by pipeline, the other end of described vacuum breaker and one adds pipe and links to each other, pipeline between described synthetic glass ejector and the described vacuum breaker is provided with diaphragm, diaphragm directly demonstrates the pressure size of pipeline, and vacuum breaker is used for preventing that the soup that adds pipe from flowing backwards.
Further, described rising pipe is provided with first variable valve, is convenient to regulate the clear water flow size.
Further, the pipette between described under meter and the synthetic glass ejector is provided with the 3rd variable valve, is used for regulating the size of medicinal liquid flow.
Further, the described pipe that adds is provided with second variable valve, is used for changing the pressure of pipeline.
The utility model is compared the advantage that has with prior art:
(1) size of soup dosage and the state that soup flows have been demonstrated intuitively;
(2) error in dipping is less;
(3) it is reliable to add process stabilization, and easy and simple to handle;
(4) adopt common water pump, substituted volume pump, saved investment, be specially adapted to vast rural area and middle-size and small-size water factory.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: base (1), valve (2), force (forcing) pump (3), first variable valve (4), synthetic glass ejector (5), diaphragm (6), vacuum breaker (7), second variable valve (8), the 3rd variable valve (9), under meter (10), water inlet pipe (11), rising pipe (12), pipette (13), add pipe (14).
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to a kind of water treatment agent throwing device shown in Figure 1, comprise base 1, be located at the force (forcing) pump 3 on the base 1, also comprise a synthetic glass ejector 5, one entrance of described synthetic glass ejector 5 links to each other through rising pipe 12 with the output terminal of described force (forcing) pump 3, the input terminus of described force (forcing) pump 3 links to each other with a water inlet pipe 11, and described water inlet pipe 11 is provided with a valve 2; Another entrance of described synthetic glass ejector 5 links to each other with a pipette 13, and described pipette 13 is provided with under meter 10; The outlet of described synthetic glass ejector 5 links to each other by the end of pipeline with a vacuum breaker 7, and the other end of described vacuum breaker 7 and adds pipe 14 and links to each other, and the pipeline between described synthetic glass ejector 5 and the described vacuum breaker 7 is provided with diaphragm 6.
Further, described rising pipe 12 is provided with first variable valve 4.
Further, the pipette 13 between described under meter 10 and the synthetic glass ejector 5 is provided with the 3rd variable valve 9.
Further, the described pipe 14 that adds is provided with second variable valve 8.
During use, pipeline and the pipette 13 of the liquid of waiting to offer medicine is connected, fresh water pipeline and water inlet pipe 11 are connected.Open valve 2, start force (forcing) pump 3, regulate first variable valve 4 and second variable valve 8 then, when clear water when first variable valve 4 is flowed through synthetic glass ejector 5, produce negative pressure and soup is sucked the synthetic glass ejector form mixed solution and penetrated by pipeline; Regulate the medicinal liquid flow size with the 3rd variable valve 9 again, observe numerical value in the under meter 10.When reaching the value that need add, stop force (forcing) pump 3 earlier, valve-off 2, this moment, vacuum breaker 7 cut out automatically, and the mixed solution that prevents from adding in the pipe 14 flows backwards.Wherein second variable valve 8 can change pipeline pressure, and the force value size can directly show from diaphragm 6.
