Compared with the prior art, the device can automatically close the internal circulation pipeline after the self-priming process is completed and flexibly and stably control so that the water outlet efficiency of the water pump is high, can be widely applied to all types of self-priming pumps, and has broad market prospect.

Description

The inner circulation type self-priming pump only follows device automatically

Technical field

The utility model belongs to the pump technical field, is specifically related to a kind of inner circulation type self-priming pump and only follows device automatically.

Background technique

General in the market JET series self-priming pump, this self-priming pump has the pipeline from the diversion of water outlet position to water inlet, after finishing, the self-priming process still carries out the self-priming circulation, the water of water outlet is continued the Absorb Water backflow, cause water-outlet quantity obviously to descend, water-outlet quantity descends more outstanding when high-lift.Open day on December 16th, 1992, publication number CN1067098A disclosed denomination of invention: the high-efficient self-priming pump of gas-liquid separation chamber's energy break-make, it is characterized in that Drainage pipe separates and protrudes upward gas-liquid separation chamber directly is communicated with main spiral case inner chamber, gas-liquid separation chamber communicates with Drainage pipe by valve and conduit component, gas-liquid separation chamber bottom discharge orifice once communicates with main spiral case inner chamber, and the top of its top through hole is furnished with a drain tap.Though this patent structure have can stop in the circuit ball valve, the current of water outlet are not over against answering internal recycle pipeline, cause the hydraulic pressure instability in the internal recycle pipeline, cause ball valve control insensitive, energy-saving effect is undesirable.

Summary of the invention

Have above-mentioned defective at prior art, the purpose of this utility model can be closed internal recycle pipeline after being to provide a kind of self-priming process to finish automatically, and control is sensitive stable, makes the high inner circulation type self-priming pump of water pump water outlet efficient only follow device automatically.

For achieving the above object, the technical solution adopted in the utility model is: this inner circulation type self-priming pump only follows device automatically and has the gas-liquid separation chamber that is positioned at pump body, it is characterized in that: the circulating water intake place, bottom of described gas-liquid separation chamber is connected with pipeline valve by pipeline, main water outlet lower end at water pump is provided with the pipeline valve control mechanism, described pipeline valve control mechanism has the ferrule sleeve with the corresponding setting of water pump master water outlet, the waterexit end of ferrule sleeve is provided with exhaust port, longitudinal separation offers a plurality of effluent troughs on the inwall of ferrule sleeve waterexit end, be provided with a spheroid that can in endoporus, move up and down in the ferrule sleeve endoporus, spheroid is hinged by connecting rod and spiral arm, and the spiral arm the other end is fixedlyed connected with the knob of pipeline valve.

Adopt the beneficial effect of technique scheme: this inner circulation type self-priming pump only follows device automatically and has the pipeline valve that connects by pipeline at circulating water intake place, the bottom of gas-liquid separation chamber, water outlet lower end at water pump is provided with the pipeline valve control mechanism, the corresponding setting of ferrule sleeve in the pipeline valve control mechanism with pump outlet, the water that water pump pumps is all discharged through ferrule sleeve, so hydraulic pressure herein is big and stable, be provided with a spheroid that can in endoporus, move up and down in the ferrule sleeve endoporus, spheroid is hinged by connecting rod and spiral arm, the spiral arm the other end is fixedlyed connected with the knob of pipeline valve, the pipeline valve control mechanism adopts lever principle that pipeline valve is controlled, control is sensitive, the open and close of pipeline valve is effective, the waterexit end of ferrule sleeve is provided with exhaust port, gas can be discharged from exhaust port when in the water pump gas being arranged, longitudinal separation offers a plurality of effluent troughs on the inwall of ferrule sleeve waterexit end, during water pump water outlet, spheroid is positioned at ferrule sleeve effluent trough position, during not water outlet of water pump, spheroid is positioned at the ferrule sleeve endoporus does not have the effluent trough position, this design, increase the regulation range of connecting rod and spiral arm, adapted to the pressure requirement of different water pumps.The present invention utilizes drag force to control ending of self-loopa current and logical, and the water pump self-loopa stops when no gas, water pump water outlet efficient height.The design is applied in the JET-150 type self-priming pump and makes product of the present invention be the contrast experiment with JET-150 type self-priming pump under different condition, water outlet efficient obviously improves, as to inhale journey be that 1 meter lift is when being 10 meters, water outlet efficient improves about 50%, correspondingly finish same water-outlet quantity, saving power loss 35%.

Below in conjunction with accompanying drawing specific embodiment of the utility model is further specified.
