Add, although adopting this method is simple, but there are following problems, the one, the price of quantitative pump is more expensive, will adopt multiple quantitative pumps on water treatment equipment, cause the price of water treatment equipment to be high; It is an electrical product that is easily affected by temperature, voltage, etc., resulting in an inaccurate amount of liquid medicine input through the quantitative pump.

Utility model content

The utility model provides a quantitative dosing device for water treatment equipment in order to solve the problem of high price of water treatment equipment and inaccurate amount of dosing liquid caused by the use of quantitative pumps in current water treatment equipment to add medicinal liquid.

In order to achieve the above functions, the technical solution provided by the utility model is:

A quantitative dosing device for water treatment equipment, comprising a water inlet pipe and a water outlet pipe, the quantitative dosing liquid device also includes a quantitative container, a float valve and a switch valve, the float valve is fixedly arranged in the quantitative container, The water inlet pipe and the water outlet pipe are respectively connected with the quantitative container, and the switch valve is arranged on the water outlet pipe.

Preferably, the float valve includes a bracket and a metal rod rotatably arranged on the bracket, one end of the metal rod is provided with a water plug, and the other end is provided with a float ball, and the water plug is used to open and close the water inlet pipe .

Preferably, the switching valve is a regulating valve.

Preferably, the floating ball is provided with a threaded through hole, and the metal rod is provided with an external thread matched with the threaded through hole, and the relative relationship between the floating ball and the metal rod is adjusted through thread fit. Location.

The beneficial effects of the utility model are: a quantitative dosing device for water treatment equipment, including a water inlet pipe and a water outlet pipe, the quantitative dosing liquid device also includes a quantitative container, a float valve and a switch valve, the float valve is fixed It is arranged in the quantitative container, the water inlet pipe and the water outlet pipe are respectively connected with the quantitative container, and the switch valve is arranged on the water outlet pipe; by setting the float valve and the water outlet pipe in the quantitative container Set the on-off valve on the outlet pipe. When a certain amount of liquid medicine is stored in the quantitative container, the float valve will make the water inlet pipe in a closed state under the action of the buoyancy of the liquid medicine. When the on-off valve on the water outlet pipe is opened, quantitative The liquid medicine in the container will flow into other containers of the water treatment equipment through the outlet pipe. At this time, the float valve opens, and the liquid medicine on the water inlet pipe flows into the quantitative container. As the liquid level of the liquid medicine in the quantitative container rises gradually, the floater will The valve will close the water inlet pipe again, and the utility model can realize quantitative dosing of liquid medicine. Compared with the method of using a quantitative pump, the utility model is cheap and accurate in measurement.

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing 1, the utility model is further elaborated:

A quantitative dosing device for water treatment equipment as shown in Figure 1 includes a water inlet pipe 1, an outlet pipe 2, a quantitative container 3, a float valve 4 and a switch valve 5, and the float valve 4 is fixedly arranged in the quantitative container 3. The water pipe 1 and the water outlet pipe 2 are connected with the quantitative container 3 respectively, and the switch valve 5 is arranged on the water outlet pipe 2 . In this embodiment, the on-off valve 5 is preferably a regulating valve with stable performance.

In this embodiment, the float valve 4 includes a bracket 41 and a metal rod 42 that is rotatably arranged on the bracket 41. One end of the metal rod 42 is provided with a water plug 43, and the other end is provided with a float 44. The water plug 43 is used for opening and closing. Close the water inlet pipe 1; the floating ball 44 is provided with a threaded through hole, and the metal rod 42 is provided with an external thread matched with the threaded through hole, and the relative position between the floating ball 44 and the metal rod 42 is adjusted through thread cooperation. By adjusting the position of the floating ball 44, the amount of dosing liquid can be realized to achieve the purpose of quantitative dosing liquid. For the convenience of use, we can engrave different dosing liquids on the matching part of the metal rod 42 and the floating ball 44 The volume scale is convenient for the operator to adjust.

When a certain liquid medicine is stored in the quantitative container 3, the floating ball 44 makes the water plug 43 press the water inlet of the water inlet pipe 1 tightly through the metal rod 42 under the buoyancy of the medicine liquid, so that the water inlet pipe 1 is in a closed state; When the switch valve 5 on the water outlet pipe 2 is opened, the liquid medicine in the quantitative container 3 will flow into other containers 6 of the water treatment equipment through the water outlet pipe 2, and at this time, the float 44 will drop to drive the water plug 43 away from the water inlet pipe 1 Since the liquid medicine on the water inlet pipe 1 has pressure, the medicine liquid on the water inlet pipe 1 will flow into the quantitative container 3, and as the liquid level of the liquid medicine in the quantitative container 3 rises gradually, the floating ball 44 rises to pass through The metal rod 42 makes the water plug 43 press the water inlet of the water inlet pipe 1 again so that the water inlet pipe 1 is closed.

The above-described embodiments are only preferred examples of the utility model, and are not intended to limit the scope of implementation of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent scope , should be included in the utility model patent application scope.
