Abstract
The utility model relates to an improved type check valve for an outlet of an air pump, which is composed of a cylinder body, and an end cover. The end of the cylinder body is provided with an air outlet pipe, and the other end of the cylinder body is provided with the end cover; the outer end of the end cover is provided with an air inlet pipe which is communicated with the air pump; the interior of the cylinder body is provided with a hairspring push valve sheet, and the hairspring push valve sheet supports and lies against an air outlet which is arranged at the inner end of the end cover. The utility model is characterized in that the inner bottom surface of the cylinder body is provided with a plurality of vent grooves; the vent grooves are communicated to the air inlet end of the air outlet pipe of the cylinder body. Because the inner bottom surface of the cylinder body is provided with a plurality of the vent grooves for discharging air, the utility model has the effect of air discharging smooth.
Description
The utility model relates to air pump, refers in particular to a kind of check valve of follow-on air pump outlet.
Usually when aquarium or crawl are breeded fish, air pump commonly used is imported air, increase the oxygen content in the water, satisfy the demand of fish, because of the outlet end of air pump gos deep in the water, aqueous reflux takes place when preventing that air pump from stopping operating damage air pump, the air delivery side of pump of being everlasting installing check valve, the check valve structure of air pump outlet commonly used as shown in Figure 6 and Figure 7, be made up of cylindrical shell a and inner sleeve b, the end of cylindrical shell a is provided with the steam outlet pipe a1 that gos deep in the water, in the other end installing inner sleeve b, the outer end of this inner sleeve b is provided with the suction tude b1 that links to each other with air pump, and installing hairspring c ejection valve block d leans on the inner air outlet of inner sleeve b in the cylindrical shell a.When starting air pump, pressurized air is flowed in the cylindrical shell a by the suction tude b1 of inner sleeve b, and d backs down with valve block, and air is entered in the water by the steam outlet pipe a1 of cylindrical shell a; When air pump stopped operating, spring c pushing tow valve block d leaned in the outlet side of inner sleeve b, prevented that aqueous reflux from going into air pump.Its major defect is: when the displacement of air pump is big, hairspring c in the cylindrical shell a is urged easily and bears against into tubulose, as shown in Figure 7, makes the interval between the line footpath of hairspring c very little, become the obstruction of exhaust, make check valve lose the effect of forward exhaust.
At above-mentioned defective, the inventor creates the technical solution of the utility model through repeatedly research and experiment.
The purpose of this utility model is to provide a kind of check valve of follow-on air pump outlet, is provided with most vent slots on the inner bottom surface of cylindrical shell, discharges for air, overcomes the drawback of prior art, reaches exhaust purpose smoothly.
The purpose of this utility model is achieved in that a kind of check valve of follow-on air pump outlet is made up of cylindrical shell and end cap, the end of cylindrical shell is provided with steam outlet pipe, end is installed end cap in addition, the outer end of this end cap is provided with the suction tude that is connected with air pump, installing hairspring ejection valve block leans on the air outlet of end cap the inner in the cylindrical shell, it is characterized in that: the inner bottom surface of this cylindrical shell is provided with most vent slots, and this vent slot is communicated on the inlet end of steam outlet pipe of this cylindrical shell.
Major advantage of the present utility model is: owing to be provided with most vent slots for the air discharge on the inner bottom surface of cylindrical shell, have exhaust effect smoothly.
The utility model is further specified as follows below in conjunction with drawings and Examples:
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a decomposing state schematic representation of the present utility model;
Fig. 3 is an exhaust condition cross-sectional schematic of the present utility model;
Fig. 4 is a non-return state cross-sectional schematic of the present utility model;
Fig. 5 is a cylindrical shell inside structure schematic representation of the present utility model;
Fig. 6 is the cross-sectional schematic of common structure;
Fig. 7 is the blocked state cross-sectional schematic of common structure.
Consult Fig. 1-Fig. 5, the utility model is made up of cylindrical shell 1 and end cap 2, the end of cylindrical shell 1 is provided with steam outlet pipe 11, end is installed end cap 2 in addition, the outer end of this end cap 2 is provided with the suction tude 21 that is connected with air pump, installing hairspring 3 ejection valve blocks 4 lean on the air outlet 22 of end cap 2 the inners in the cylindrical shell 1, and the inner bottom surface of this cylindrical shell 1 is provided with most vent slots 12, and this vent slot 12 is communicated on the inlet end 110 of steam outlet pipe 11 of this cylindrical shell 1.
When starting air pump, pressurized air is flowed into by the suction tude 21 of end cap 2, and valve block 4 is backed down, air is discharged by the steam outlet pipe 11 of cylindrical shell 1, because of valve block 4 is soft flake structure, is circular-arc with compressed-air actuated promotion, form bigger through-flow space, make exhaust smooth and easy; When suction pressure was big, hairspring 3 abutted against because of valve block 4 retreats and is compressed into tubulose together, and pressurized air still can be discharged by the inlet end 110 of steam outlet pipe 11 along vent slot 12, the situation that exhaust is blocked can not take place, as shown in Figure 3.
When air pump shut down, hairspring 3 roof pressure valve blocks 4 were against on the inner air outlet 22 of end cap 2, avoid aqueous reflux to go into air pump, as shown in Figure 4.
