Abstract
The utility model relates to an air inlet valve of an air compressor, which comprises a hollow upper valve without both ends open, a hollow lower valve without both ends open, a hollow counterweight room, a counterweight and a closed cover; the upper valve and the lower valve are connected, and the joint is provided with a closed cover seat; the counterweight room is arranged on the outer side of the joint of the upper valve and the lower valve; the closed cover is arranged in the inner cavity of the lower valve which is close to the upper valve; one end of the closed cover is connected with the counterweight in the counterweight room by a pin shaft; the upper side face of the closed cover is matched with the closed cover seat. The air inlet valve of the air compressor has very simple structure, obviously higher service life, is convenient to be repaired, and has high practical value, so that the air inlet of a compressor host can be reliable and stable; the air inlet valve processing and assembly as well as the maintenance process and practical performance can be improved.
Description
Technical field
The utility model relates to a kind of suction valve.
Background technique
Suction valve is one of important accessory of air compressor, and the air inflow of air compressor is controlled by suction valve.Therefore, the quality of the performance of suction valve will directly influence the normal operation of air compressor.
At present, many patent disclosures technology separately, as Chinese patent, application number: 200610050162, the technology that discloses of 03227016.x and 03247661.2.
In above-mentioned patent, all use the action of elastic element such as spring controlled valve core, its existing defective is conspicuous, after elastic element uses a period of time, will produce fatigue, confining gas passage that can not be tight causes the compressor cisco unity malfunction.
Summary of the invention
The purpose of this utility model provides a kind of air compressor suction valve, to overcome the above-mentioned defective that exists on the prior art.
Air compressor suction valve of the present utility model, comprise the both ends open of hollow upper valve body, hollow both ends open following valve body, hollow balancing weight chamber, balancing weight and close lid;
Said upper valve body is connected with following valve body, the joint is provided with closes cage, said balancing weight chamber is arranged on the outside of upper valve body and following valve body joint, the said lid that closes is arranged in the inner chamber near the following valve body at upper valve body place, the one end is connected with balancing weight in being arranged on the balancing weight chamber by bearing pin, its upper side matches with closing cage, so that can upper valve body is isolated with the cavity of following valve body.
Air compressor suction valve working principle of the present utility model:
When not having gas to enter upper valve body, rely on the gravity of balancing weight, the said lid that closes moves upward, and cooperates with the said cage that closes, with the cavity isolation of upper valve body with following valve body; And when compressor operating, following valve body produces vacuum, and the said lid that closes then reverses downwards, and the gas in the upper valve body then can enter down valve body.
Air compressor suction valve of the present utility model, structure is very simple, and significantly improve working life, and easy access, has bigger use value.
Air compressor suction valve main feature of the present utility model is simple in structure, and significantly improve working life, and easy access, has bigger use value.
