Abstract

The utility model relates to a water pump matched with a boiler, which is composed of a motor, a pump, a water returning can, a valve, a water returning pipe, natural-circulation communicating pipes and a flow meter. The utility model is characterized in that the valve and one natural-circulation communicating pipe are arranged on the water returning pipe. The valve and the flow meter are arranged on the natural-circulation communicating pipe. When the water pump is operated, the water pump has the function of automatically adjusting pressure. When the water pump is stopped, water for heating circulation can naturally circulate, so that the utility model has the double functions of constraint and automation.

Description

A kind of water pump

The utility model belongs to a kind of pump, the specifically a kind of and matching used water pump of boiler.

At present,, when pump water in boiler, all need electricity consumption to start water pump, in operation process, can't adjust pressure, and heating circuit water can not be done natural circulation at boiler room and the matching used water pump of boiler.

The purpose of this utility model is, design a kind ofly can adjust pressure automatically when starting water pump, and heating circuit water still can do natural circulation when water pump quits work, promptly have strong from and the water pump of dual functions effect automatically.

Major technique content of the present utility model is, this water pump is made of motor, pump, backwater jar, valve, return pipe, natural circulation connecting tube, flowmeter, it is characterized in that, on return pipe, settle a valve and a natural circulation connecting tube, and on connecting tube, a valve and a flowmeter are set in natural circulation.Its working principle during use, starts water pump earlier, and behind the starting mode of pump, this pump is just adjusted pressure automatically, and when water pump quit work, heating water still can be done automatic cycle.

The utility model is compared the advanced part that is had and is with prior art, this water pump has automatic adjustment pressure, makes characteristics such as heating water energy automatic cycle, thereby has overcome the single deficiency of existing water pump function.

Description of drawings:

Fig. 1 is the utility model overall appearance structural representation;

Fig. 2 is the utility model structural system schematic representation;

Wherein, 1 motor, 2 pumps, 3 backwater jars, 4 valves, 5 return pipes, 6 natural circulation connecting tube, 7 valves, 8 flowmeters, 9 valves.

Below in conjunction with accompanying drawing 1-2 the utility model is remake description further, pump 2 is connected on the motor 1, load onto a return pipe 5 at the front end of pump 2, on return pipe 5, be equipped with backwater jar 3, valve 4, natural circulation connecting tube 6, valve 7 and flowmeter 8 respectively, settle a valve 9 on the top of pump 2, more than just constitute the utility model.

Claims (1)

1. A kind of water pump, constitute by motor, pump, backwater jar, valve, return pipe, natural circulation connecting tube, flowmeter, it is characterized in that, on return pipe, settle a valve and a natural circulation connecting tube, a valve and a flowmeter are set on connecting tube in natural circulation.
