The preferred embodiment of the utility model is shown, it should be appreciated that it is new that those skilled in the art can change described here practicality
Type, and still realize the advantageous effects of the utility model.Therefore, description below should be understood as those skilled in the art
It is widely known, and be not intended as the limitation to the utility model.
For clarity, whole features of practical embodiments are not described.In the following description, it is not described in detail well known function
And structure, because they can make the utility model chaotic due to unnecessary details.It will be understood that in any practical embodiments
Exploitation in, it is necessary to make a large amount of implementation details to realize the specific objective of developer, such as according to related system or related quotient
The limitation of industry changes into another embodiment by one embodiment.Additionally, it should think this development may be it is complicated and
It is time-consuming, but it is only to those skilled in the art routine work.
The utility model is more specifically described by way of example with reference to attached drawing in the following passage.According to following explanation and power
The advantages of sharp claim, the utility model and feature will become apparent from.It should be noted that attached drawing using very simplified form and
Using non-accurate ratio, only to purpose that is convenient, lucidly aiding in illustrating the utility model embodiment.
As shown in Figure 1, the utility model proposes a kind of Ultra-High Efficiency self-priming pump group, including the pump housing 1, water inlet pipe 11, go out
Water pipe 12 and the gas-liquid separation chamber 13 being connected with outlet pipe 12, which is characterized in that metal mesh 2, gas are equipped in gas-liquid separation chamber 13
The top side wall of liquid separation chamber 13 is equipped with exhaust outlet 130, and automatic closing gear 3 is equipped at exhaust outlet 130.Further, into
Water pipe 11 is equipped with air admission valve 110, and outlet pipe 12 is equipped with check-valves 120, and metal mesh 2 be in the taper that raises up or
Arc, the landing of accelerating liquid.Since gas is different from the particle size of liquid, liquid passes through silk metal together with gas mixing
Net 2, gas therein as be sieved generally by, but liquid stays in the upper and lower surface of metal mesh 2 due to surface tension is intercepted,
Fail in large quantities through metal mesh, and accelerate gas-liquid separation downstream to 13 bottom of gas-liquid separation chamber under gravity
Rate.
Specifically, as shown in Figure 1 to Figure 3, automatic closing gear 3 includes float 31 and stopper 32, and 32 one end of stopper can revolve
The bottom end side for being connected to exhaust outlet 130 turned, the other end are connected with float 31.Gas-liquid separation chamber 13 the pump housing 1 just start when into
The work of row separation gas-liquid mixture simultaneously discharges gas, and since outlet pipe 12 is equipped with check-valves 120, gas is from exhaust outlet 130
Discharge accelerates the rate of discharge of gas, while float 31 promotes stopper 32 to keep hang under gravity, ensures
Exhaust outlet 130 it is unimpeded.And liquid influent pipe 11 enters and flows through gas-liquid separation chamber 13 and from water outlet in the pump housing 1 after gas drains
Pipe 12 flows out, and liquid level rises in gas-liquid separation chamber 13, and float 31 is made to float, and stopper 32 is driven to turn down upwards and blocks exhaust outlet
130, liquid is avoided to be flowed out from exhaust outlet 130.
Further, as shown in Figure 1 to Figure 3, exhaust outlet 130 is circumscribed with U-shaped exhaust pipe 4, and one end of U-shaped exhaust pipe 4 is
Exhaust gas intake port end 41, the other end are air exit end 42, and exhaust gas intake port end 41 is connected with exhaust outlet 130.It is set in U-shaped exhaust pipe 4
There is water seal 43.The caliber at air exit end 42 is more than exhaust gas intake port end 41, and half of radial direction block is equipped in air exit end 42
The portion 44 that intercepts water of pipeline.When being exhausted, gas enters along U-shaped exhaust pipe 4 from exhaust gas intake port end 41 from row exhaust outlet 130
The gas port of export 42 is discharged, and water seal 43 is pushed through air exit end 42 by the water seal 43 in the U-shaped exhaust pipe 4 of gas extrusion, due to row
42 caliber of the gas port of export becomes larger, and gas is facilitated to be discharged above water seal 43.Meanwhile water seal 43 is stopped by the portion of intercepting water 44 and being arranged
In the gas port of export 42, when no gas is discharged, U-shaped 4 bottom bending place of exhaust pipe is flowed back in water seal 43 under gravity, by U
Type exhaust pipe 4 blocks, and the air outside pipe is avoided to enter in the pump housing 1 from air exit end 42.
Self priming pump must fill clear water or institute's pumped (conveying) medium when starting for the first time in the pump housing 1, pass through the height of impeller after startup
Speed is rotated in the quick separating that gas-liquid is realized in the gas-liquid separation chamber 13 of the pump housing 1 itself, and the air in 1 water inlet pipe 11 of the pump housing is continuous
It is discharged, vacuum is formed in water inlet pipe 11, it is achieved thereby that the self-priming course of work of the pump housing 1.During termination of pumping, stopping on outlet pipe 12
It returns valve 120 to close, has separated the reflux of high-order medium in outlet pipe 12, while the air admission valve 110 on water inlet pipe 11 synchronizes
It opens, air enters water inlet pipe 11, destroys the vacuum state in water inlet pipe 11, thoroughly avoids what is caused by siphonage
In the pump housing 1 the defects of medium back flow emptying, remained in the fluid reservoir in the pump housing 1 and pumped medium material, realize one
Secondary drainage liquid filling, the purpose of the lifelong self-priming of water pump.
To sum up, in the present embodiment, a kind of Ultra-High Efficiency self-priming pump group of proposition accelerates gas-liquid point by metal mesh 2
Rate from gas-liquid separation in room 13, makes air quickly be discharged from exhaust outlet 130, and is closed after gas drains using automatic
Mechanism 3 blocks exhaust outlet 130, and liquid is avoided to be flowed out from exhaust outlet 130.
The preferred embodiment of the utility model is above are only, does not play the role of any restrictions to the utility model.
Any person of ordinary skill in the field, in the range of the technical solution of the utility model is not departed from, to the utility model
