Abstract
The invention discloses a liquid pump air extraction device and relates to pumps. A liquid inlet pipe and a liquid outlet pipe are arranged on a pump body; an extraction pump is arranged on one side of the liquid outlet pipe; an air inlet valve is arranged on the liquid inlet pipe and is communicated with the extraction pump; an air outlet valve is arranged on the extraction pump; and a sealing valve is arranged on the liquid outlet pipe. Because the air inlet valve is arranged on the liquid inlet pipe and is communicated with the extraction pump, the air outlet valve is arranged on the extraction pump, and the sealing valve is arranged on the liquid outlet pipe, and the liquid pump air extraction device is low in water outlet resistance, low in energy consumption, high in efficiency, and suitable for a liquid pump to be extracted before work.
Description
Technical field
The present invention relates to the pump class, is a kind of liquid pump air extractor specifically.
Background technique
We know, existing liquid pump air extractor is to be provided with liquid inlet pipe and drain pipe on the pump housing, and drain pipe one side is provided with extraction pump, extraction pump is connected with drain pipe, extraction pump is respectively equipped with gas outlet valve and suction valve in both sides up and down in the drain pipe, and this liquid pump air extractor is because extraction pump is respectively equipped with gas outlet valve and suction valve in both sides up and down in the drain pipe, dwindled the effective diameter of pipe of drain pipe, it is big to go out water resistance, and power consumption is high, and efficient is low; Because fluid need be backed down the twice valve, it is big to go out water resistance, and power consumption is high, and efficient is low.
Summary of the invention
The technical problem that the present invention solves is, it is big to solve out water resistance, and power consumption is high, and inefficient problem provides that a kind of to go out water resistance little, and it is low to consume energy, the liquid pump air extractor that efficient is high.
Technological scheme of the present invention is, the pump housing is provided with liquid inlet pipe and drain pipe, and drain pipe one side is provided with extraction pump, and the main structure characteristics are, liquid inlet pipe is provided with suction valve, and suction valve communicates with extraction pump, and extraction pump is provided with gas outlet valve, and drain pipe is provided with seal valve.
Suction valve communicated with extraction pump through connecting tube; Seal valve is provided with depression bar.
The invention has the beneficial effects as follows that because liquid inlet pipe is provided with suction valve, suction valve communicates with extraction pump, extraction pump is provided with gas outlet valve, and drain pipe is provided with seal valve, and it is little to go out water resistance, and it is low to consume energy, the efficient height.The present invention is applicable to needs the liquid pump of bleeding before the work.
Description of drawings
Accompanying drawing is a kind of schematic representation of the present invention, also is a kind of embodiment's schematic representation.
Fig. 1 is a plan view, and Fig. 2 is the right elevation of Fig. 1.
Mode of execution
Liquid pump air extractor as shown in the figure, the pump housing 6 is provided with liquid inlet pipe 1 and drain pipe 8, drain pipe 8 one sides are provided with extraction pump 4, and liquid inlet pipe 1 is provided with suction valve 2, and suction valve 2 communicates with extraction pump 4, as can be seen from Figure 1, suction valve 2 communicated with extraction pump 4 through connecting tube 3, and extraction pump 4 is provided with gas outlet valve 5, and drain pipe 8 is provided with seal valve 7, seal valve 7 is provided with depression bar 9, and depression bar 9 has the function of guiding and manually-operable seal valve 7.Seal valve 7 sealing liquid outlets 8 when extraction pump 4 begins to bleed, suction valve 2 is opened, and gas enters extraction pump 4 by connecting tube 3, discharges through gas outlet valve 5, and it is little to go out water resistance, and it is low to consume energy, the efficient height.Also can manually depress depression bar 9 when extraction pump 4 begins to bleed, improve tightness, accelerate pumping speed.
