The telescopic control device comprises a pressing screw and an upward pushing spring, a through hole which is vertically arranged is formed in the wall body of the valve body or the valve casing, the upper section of the flow adjusting plate is inserted into the lower part of the through hole, the pressing screw is screwed into the upper section of the through hole and mutually forms thread fit, and the upward pushing spring is arranged on the outer wall of the air outlet and forms upward pushing of the flow adjusting plate.
The side wall of the flow adjusting plate extends outwards to form an extension arm, and the upward spring is pressed between the extension arm and the outer wall of the air outlet.
After adopting the technical scheme, the beneficial effects of the utility model are that: this technique is through addding the flow control board in the gas outlet department of check valve, and the flow of check valve just can be controlled to the volume of inserting of control flow control board, and two kinds of functions are realized to a valve, can simplify pipeline structure, reduce the finished product.
Description of the drawings:
FIG. 1 is a structural diagram of the check valve of the present invention;
FIG. 2 is an enlarged view of the structure of FIG. 1;
fig. 3 is an exploded structural view of fig. 2.
The specific implementation mode is as follows:
the present technology is further described below with reference to the accompanying drawings.
The special check valve of air compressor of this embodiment, including valve body 1, valve casing 2, valve gap 3, case 4, air inlet 5 and gas outlet 6, valve body 1 and valve casing 2 all are hollow structure's part, valve casing 2 injects from 1 top of valve body, and form sealed cooperation through first sealing washer 7 between the two, the shaping of valve body air inlet 5 is in the bottom, the shaping of gas outlet 6 is in the lateral wall, air inlet 5 forms the ninety degree relation of bending with gas outlet 6, make the air that comes from air inlet 5 take place ninety degrees after 5 of air inlet and bend immediately and carry, discharge from gas outlet 6. Valve gap 3 from valve casing 2 top inject and form screw-thread fit between the two, make valve gap 3 close soon in valve casing 2, valve casing 2 and valve gap 3 form sealed cooperation through second sealing washer 8, case 4 injects in valve casing 2 and just to air inlet 5, valve casing 2 inner wall forms with case 4 and leads sliding fit, promptly case 4 can be followed the interior wall of valve casing 2 and slided from top to bottom, the crimping has push down spring 9 between the top of case 4 and valve gap 3, push down spring 9 pushes down case 4, finally make 4 bottom shutoff air inlets 5 of case, prevent the circulation of air, this moment is the closed condition of this check valve. The flow rate adjusting plate 10 is inserted from above the air outlet 6. All the shaping has the amalgamation shirt rim 11 of evagination on the outer wall body of valve body 1 and valve casing 2, screw together through screw 12 after the amalgamation shirt rim 11 of both, the shaping has the through-hole 13 of vertical setting simultaneously on the amalgamation shirt rim 11 of both, the flow regulation board upper segment injects the lower part of through-hole 13, the upper portion of through-hole 13 injects there is down-pressing screw 14, down-pressing screw 14 and through-hole upper portion form screw-thread fit each other, the shaping has spout 15 that sets up from top to bottom on the valve body 1 lateral wall, it has extension arm 16 to stretch out the shaping outward on the lateral wall of flow regulation board 10, extension arm 16 passes spout 15, the crimping has top spring 17 between extension arm 16 and 6 outer walls of gas outlet, top spring 17 forms the top action to extension arm 16 and flow regulation board 10.
The working principle is as follows: air gets into from air inlet 5, and the air at this moment is the high-pressure gas who is compressed by the compressor, and after atmospheric pressure reached certain degree, atmospheric pressure will overcome the spring force of pushing down spring 9, makes case 4 up propelling movement open the air flue, and air inlet 5 and gas outlet 6 intercommunication this moment, and atmospheric pressure is big more, and the range that case 4 was opened is big more. In order to control the flow rate of the air discharged from the air outlet 6, the downward pressing screw 14 is rotated to make the downward pressing screw 14 push the flow adjustment plate 10 to move downward, and the upward top spring 17 is compressed downward by the extension arm 16 of the flow adjustment plate 10, and the amount of the air flowing through the air outlet 6 is reduced along with the downward movement of the flow adjustment plate 10. Conversely, when the down-pressing screw 14 is rotated reversely to move the down-pressing screw 14 upward, the up-pressing spring 17 will lift the extension arm 16 and the flow regulating plate 10 upward under the elastic restoring force of the up-pressing spring 17, and the air flow rate at the air outlet 6 will gradually increase. The flow of the air flowing through the one-way valve can be adjusted through the two adjusting modes.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. The invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications and variations, including those shown in the drawings and described herein. Therefore, the equivalent changes made according to the shape, structure and principle of the present invention should be covered in the protection scope of the present invention.
