Abstract
The invention discloses a kind of self-cleaning type water suction bottom valve, comprise valve body, water inlet grizzly bar and safety check, described valve body offers compressed air inlet, described compressed air inlet is between described water inlet grizzly bar and described safety check, described compressed air inlet is connected with compressed air hose, described compressed air hose connects compressed air gas source, described compressed air hose is provided with compressed air valve, the present invention mainly sets up compressed air inlet on valve body, by passing into pressurized air, pressurized air mixes with water under water, strong air-water backwashing is carried out to the water inlet grizzly bar inside of water suction bottom valve, the foreign material being attached to water suction bottom valve water inlet grizzly bar outer surface are made to depart from water suction bottom valve, therefore water suction bottom valve can be avoided to leave the water cleaning, greatly alleviate workload and equipment investment.<!--1-->
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of modified node method of the bottom valve that absorbs water.
Background technique
Water suction bottom valve is generally installed on the bottom of suction line under water pump water, in restriction pump sump pipeline, liquid returns to water source, plays the function of only import but no export, and object keeps being full of liquid in pump water inlet pipeline and impeller, make to form vacuum in impeller central during pump startup, make pump energy smooth delivery of power liquid.Have into water grizzly bar bottom water suction bottom valve, the foreign material in isolated water, avoid foreign material to block water pump vane.As shown in Figure 1, be the structure of prior art water suction bottom valve, comprise valve body 1, water inlet grizzly bar 2 and safety check 3.
In the long start-up course of water pump, foreign material in water constantly accumulate in the water inlet grizzly bar outer surface of water suction bottom valve, water suction bottom valve is blocked, the flow of water pump is caused significantly to reduce, as cleared up bottom valve not in time, part foreign material will be inhaled into water pump vane place, cause water pump normally to work, burn-down of electric motor etc.There is following defect in the routine cleaning of water suction bottom valve:
A, due to water suction bottom valve be positioned at suction line bottom under water, therefore suction line must be left the water, could to water suction bottom valve clear up;
B, as suction line caliber is large, add containing a large amount of liquid in upper pipeline, need employ Hoisting Machinery could propose suction line;
C, as suction line is positioned at pumping station, the height of suction line is greater than pumping station height, then suction sleeve also needs to install dismounting device additional, thus increases the hidden danger that suction line leaks, and too increases cost simultaneously.
D, due to water suction bottom valve be positioned under water, change water suction bottom valve operating environment comparatively severe.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of self-cleaning type water suction bottom valve, this self-cleaning type water suction bottom valve is convenient to cleaning, and without the need to cleaning of being left the water by water suction bottom valve, and structure is simple, easy to implement.
The present invention in order to the technological scheme solving its technical problem and adopt is:
A kind of self-cleaning type water suction bottom valve, comprise valve body, water inlet grizzly bar and safety check, described valve body offers compressed air inlet, described compressed air inlet is between described water inlet grizzly bar and described safety check, described compressed air inlet is connected with compressed air hose, described compressed air hose connects compressed air gas source, and described compressed air hose is provided with compressed air valve.
The invention has the beneficial effects as follows: self-cleaning type water suction bottom valve of the present invention mainly sets up compressed air inlet on valve body, by passing into pressurized air, pressurized air mixes with water under water, strong air-water backwashing is carried out to the water inlet grizzly bar inside of water suction bottom valve, the foreign material being attached to water suction bottom valve water inlet grizzly bar outer surface are made to depart from water suction bottom valve, therefore water suction bottom valve can be avoided to leave the water cleaning, greatly alleviate workload and equipment investment.
Accompanying drawing explanation
Fig. 1 is prior art water suction bottom valve structural representation;
Fig. 2 is that the present invention absorbs water bottom valve structural representation;
Fig. 3 is the using state figure of the present invention when cleaning;
Fig. 4 is the A portion enlarged view of Fig. 3.
Embodiment
Below by way of specific instantiation, the specific embodiment of the present invention is described, those of ordinary skill in the art can understand advantage of the present invention and effect easily by content disclosed in the present specification.The present invention also can be implemented in further, different ways, that is, not departing under disclosed category, can give different modifications and change.
Embodiment: a kind of self-cleaning type water suction bottom valve, comprise valve body 1, water inlet grizzly bar 2 and safety check 3, described valve body 1 offers compressed air inlet 4, described compressed air inlet 4 is between described water inlet grizzly bar 2 and described safety check 3, described compressed air inlet 4 is connected with compressed air hose 5, described compressed air hose 5 connects compressed air gas source, and described compressed air hose 5 is provided with compressed air valve 6.
Before water suction bottom valve is cleared up, water pump 7 cuts out, pump early gate 8 is closed simultaneously, open pressurized air valve, due to the closedown of pump early gate, the air-water mixture that pressurized air and water are formed, grizzly bar of can only intaking in water suction bottom valve flows out at a high speed, therefore make the foreign material of attachment, take away with air-water mixture.
The present invention mainly sets up compressed air inlet on valve body, by passing into pressurized air, pressurized air mixes with water under water, strong air-water backwashing is carried out to the water inlet grizzly bar inside of water suction bottom valve, the foreign material being attached to water suction bottom valve water inlet grizzly bar outer surface are made to depart from water suction bottom valve, therefore water suction bottom valve can be avoided to leave the water cleaning, greatly alleviate workload and equipment investment.
