Cylinder cover of air compressor capable of directly connecting exhaust pipe

Abstract

The present invention relates to a cylinder cover of an air compressor, especially a cylinder cover of an air compressor capable of directly connecting an exhaust pipe. The cylinder cover includes a suction hole, an exhaust hole, a suction channel, an exhaust channel, an isolation belt arranged between the suction hole and the exhaust hole, the suction hole and the exhaust hole are respectively communicated with the suction channel and the exhaust channel, a first length from the center of the isolation belt to one end of the exhaust channel is more than a second length from the center of the isolation belt to one end of the suction channel, the second length is covered on a valve plate completely, a third length of the first length that is equal to the second length is covered on the valve plate completely, an extending end of the first length is an expanding projection, and an exhaust pipe connection part with an exhaust outlet is arranged below the expanding projection. Compared with the existing technology, the exhaust outlet communicated with the exhaust channel is arranged below the expanding projection, the exhaust pipe can be directly connected to the exhaust outlet without an additional member, such that it is not only possible to fulfill piping operation, but also to reduce cost effectively.

Description

Technical field: [0001] The invention relates to a cylinder head for an air compressor, in particular to a cylinder head for an air compressor which can be directly connected to an exhaust pipe. Background technique: [0002] For ordinary piston air compressors for the purpose of producing compressed air, the pump base and the motor base are usually placed on a horizontal air storage tank, and there are compression pumps and motors for driving the compression pumps on the above two bases, or The motor of the direct-connected compression pump is single-arranged on the motor base. [0003] The compression pump has a valve plate with suction and exhaust holes. The cylinder head is set on the upper end of the compression cylinder. There are suction and exhaust valves between the cylinder head and the valve plate. The external air is sucked into the compression cylinder through the cylinder head, and then the air Compress, and finally discharge the compressed air. [0004] Comp...

AI Technical Summary

Problems solved by technology

[0005] But the cylinder head of prior art, in the batch production process of using aluminum material with the mode of injection molding, forms suction port and exhaust port by a pair of sand cores of horizontal direction, in order to vertically be contained in exhaust pipe 4 On the mouth, a 90° joint 25 must be added, which leads to complicated piping operations and increased costs

[0006] In order to solve the above problems, the exhaust pipe can be connected horizontally to the exhaust port, and then the exhaust pipe can be bent downward, but the bending process is not easy to do, and it will hinder the smooth flow of compressed air, especially the motor at the horizontal connection. The cooling air generated by the cooling fan on the opposite load side cannot cool the exhaust pipe in time

[0007] Moreover, the safety valve installed to prevent the storage of a pressure higher than the set pressure of the gas storage tank is usually installed on the gas storage tank, and many inconveniences will be encountered in the workshop conditions where the safety valve cannot be installed on the gas storage tank. Therefore, there is a need for a technology that can easily install the safety valve on the exhaust line of the cylinder head without being restricted by the site.
