Abstract
The utility model relates to a self-suction pump for preventing evacuation, which comprises a pump body and a vane wheel which is arranged in the pump body, wherein the pump body is provided with an inlet and an outlet. The inlet and the outlet are respectively connected with a water inlet pipe and a water outlet pipe, wherein the water inlet pipe is provided with a vacuum breaking valve. Compared with the prior art, the utility model is provided with the vacuum breaking valve on the water inlet pipe of the self-suction pump. When the self-suction pump is stopped, the vacuum breaking valve is immediately broken so that vacuum at the inlet of the self-suction pump is eliminated. When the pump is started, the vacuum breaking valve is immediately closed so that the establishment of negative pressure at the inlet of the self-suction pump is ensured.
Description
Technical field
The utility model relates to water pump, relates in particular to self-priming pump, particularly a kind of self-priming pump of finding time of preventing.
Background technique
Self-priming pump is to utilize in the ingress of pump generation negative pressure water is sucked in the pump chamber from the external world, and discharges through delivery side of pump.In order to form effective negative pressure, when using self-priming pump for the first time, need in pump, pour water, to discharge the air in the pump chamber so that can effectively form negative pressure during pump work from delivery side of pump.But after existing self-priming pump stops, the ingress of pump still is in negative pressure state, and the delivery side of pump place still is in barotropic state, so the liquid return that will make the pump housing is to inlet, when causing reusing, need to pour water in pump from delivery side of pump again, to discharge the air in the pump chamber so that can effectively form negative pressure during pump work.In order to prevent liquid return, now generally bottom valve is installed at the water inlet position of suction line, prevent to shut down the back refluence and find time.But unit problem, so this method and unreliable with regard to causing when the bottom valve of suction line breaks down.
Summary of the invention
The purpose of this utility model provides a kind of self-priming pump of finding time of preventing, the described this self-priming pump of finding time that prevents will solve in the prior art self-priming pump liquid return to the technical problem of inlet.
This self-priming pump of finding time of preventing of the present utility model, constitute by the pump housing of self-priming pump and the impeller that is arranged in the pump housing, the described pump housing is provided with entrance and exit, described inlet is connected with intake pipe, described outlet is connected with outlet pipe, wherein, described intake pipe is provided with a vacuum breaker valve.
Further, also be provided with a self-priming pump running sensing controler on the described pump housing, described sensing controler links to each other with described vacuum breaker valve.
Further, an end of described intake pipe is provided with adpting flange, and described vacuum breaker valve is arranged between the adpting flange and the pump housing.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with vacuum breaker valve on the intake pipe of self-priming pump, when self-priming pump stopped, described vacuum breaker valve was opened at once, eliminate the vacuum of the ingress of self-priming pump, when pump startup, described vacuum breaker valve cuts out at once, to guarantee setting up negative pressure in the ingress of self-priming pump.
Description of drawings
Fig. 1 is the plan view that prevents the self-priming pump of finding time of the present utility model.
Embodiment
As shown in Figure 1, the self-priming pump of finding time of preventing of the present utility model, constitute by the self-priming pump pump housing 1 and the impeller 2 that is arranged in the pump housing 1, the described pump housing 1 is provided with inlet 3 and outlet 4, be connected with intake pipe 5 and outlet pipe 6 respectively in described inlet 3 and the outlet 4, wherein, described intake pipe 5 is provided with vacuum breaker valve 7.
Further, also be provided with the sensing controler 8 that a detection self-priming pump is opened and stopped on the pump housing 1, described sensing controler 8 links to each other with described vacuum breaker valve 7.
Further, described vacuum breaker valve 7 is near the adpting flange 9 of intake pipe 5.
Working principle of the present utility model is as follows: when pump quits work, sensing controler 8 sends instruction to vacuum breaker valve 7 at once, make vacuum breaker valve 7 open at once, eliminate the vacuum at inlet 4 places of self-priming pump, thereby prevent the liquid return in the pump housing, when pump startup, sensing controler 8 sends instruction to vacuum breaker valve 7 at once, make described vacuum breaker valve 7 close at once, to guarantee setting up negative pressure at inlet 3 places of self-priming pump.
