Problems solved by technology

[0003] At present, the air intake flow rate of the brake air chamber in the application of automobile brakes cannot be adjusted. When the brakes are used, due to many reasons such as brake drums, brake pads and braking torque, it is difficult to ensure the balance of multi-wheel braking force. As a result, the wear of the tires will increase, and after the brake is released, the gas in the brake chamber will be discharged slowly, wasting energy and polluting the environment

Abstract

The invention provides a two-way check valve easy to adjust. The two-way check valve comprises a valve body, wherein an exhaust passage is arranged in the valve body; a metering pin valve is arranged on the upper side of the valve body and comprises a flow adjusting lever and a locknut; the flow adjusting lever is partially arranged in the exhaust passage and partially extends out of the valve body; the locknut is arranged on the outer side of the valve body and is used in coordination with the flow adjusting lever; the lower side of the valve body is connected with a connector through an intermediate housing or is directly connected with the connector; and an air inlet or an air outlet, which is communicated with the exhaust passage, is formed in the connector, and correspondingly, an air inlet or an air outlet, which is communicated with the exhaust passage, is formed in the side wall of the valve body. Compared with the prior art, the two-way check valve has the advantages that the air inflow can be adjusted; the braking forces of a number of wheels are balanced; after braking, air in a brake chamber can be exhausted quickly; and the two-way check valve is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of a valve for automobile braking, in particular to a two-way one-way valve with simple structure, convenient use and easy adjustment. Background technique [0002] The brake air chamber is also called the sub-cylinder, and its function is to convert the pressure of the compressed air into a mechanical force that rotates the brake camshaft to realize the braking action. The brake air chamber is a clamp-clamped diaphragm type, and its structure includes two front and rear air chambers. The front and rear brake air chambers are different in size, but their structures are basically the same. When the car brakes, air enters the brake air chamber from the air inlet, and the diaphragm is deformed under the action of air pressure, pushing the push rod, and driving the brake adjustment arm, turning the brake cam, and the brake shoe friction plate Presses against the brake drum to apply the brakes. When the car rel...
