Problems solved by technology

[0003] 1. Narrow air distribution valve and small opening of air distribution valve lead to large pressure difference on both sides of the air distribution valve, forming throttling effect and reducing air distribution efficiency
[0004] 2. The gas distribution valve and its auxiliary mechanism are loose in structure, large in size and have many parts
[0005] 3. As a movable opening and closing control mechanism, the gas distribution valve is not conducive to airtightness, and the drive is complicated
[0006] 4. It cannot work well with compressors, vacuum machines, and air motors that work in the form of rotary cylinders, and has a single function

Embodiment Construction

[0026] figure 1 It is a structural schematic diagram of the present invention, figure 2 It is an external view of the present invention, as shown in the figure, the slide valve type compression gas distribution mechanism in this embodiment includes an intake passage 73, an exhaust passage 74 and a gas distribution block 72, and the gas distribution block 72 can be driven The reciprocating sliding is used to open or close the intake port, so that the intake port or exhaust port communicates with the corresponding cylinder alternately; the intake port 73 and the exhaust port 74 are opened on the air distribution base 71, and the cylinder block The end face is provided with a gas distribution port for communicating between the cylinder and the intake passage (or exhaust passage). The gas distribution port is preferably the end opening of the cylinder. The gas distribution block 72 can be driven to slide back and forth and block the gas distribution port. By controlling the gas ...

Abstract

The invention discloses a sliding valve type gas distribution mechanism and a gas distribution method thereof. The sliding valve type gas distribution mechanism comprises an air inlet channel, an airexhaust channel and a gas distribution block, and the gas distribution block can be driven to slide in a reciprocating mode so as to open or close the air inlet channel or the air exhaust channel, sothat the air inlet channel or the air exhaust channel is alternately connected with the corresponding cylinder. By controlling the reciprocating sliding of the gas distribution block so as to controlthe phase difference between the air inlet channel or the air exhaust channel and the corresponding cylinder, the structure of the gas distribution mechanism can be simplified, the gas distribution process is improved, the gas distribution regulation is achieved, the gas distribution efficiency is improved, and the diversification of the function is achieved.

Description

technical field [0001] The invention relates to the field of transmission drive, in particular to a slide valve type gas distribution mechanism and a gas distribution method thereof. Background technique [0002] Pneumatic equipment such as compressors, vacuum machines, and air motors have a wide range of application requirements in production and life, and are indispensable and important power equipment. As an essential structure of compressors, vacuum pumps and air motors, the air distribution mechanism is one of the key mechanisms in the design of compressors and air motors. Although the traditional one-way valve type valve mechanism is simple in principle and practical in function, it has certain inherent defects: [0003] 1. The narrow air distribution valve and small opening of the air distribution valve lead to a large pressure difference between the two sides of the air distribution valve, forming a throttling effect and reducing the gas distribution efficiency. ...
