Description
Technical Field
The invention relates to a piston air compressor.
Background
The piston type air compressor drives a piston to reciprocate in an air cylinder through a crankshaft connecting rod to realize air compression. In a general piston type air compressor, when a piston is close to the axle center of a crankshaft, an air cylinder sucks air from the outside; when the piston is far away from the axle center of the crankshaft, the air in the cylinder is compressed. An important problem with such air compressors is that the piston is stressed a lot when the cylinder is inhaling and when the air is compressing, resulting in large vibrations. And such air compressors typically require staged compression due to their nature. The staged compression can reduce the exhaust temperature, save the compression work, improve the volume efficiency and increase the exhaust volume of the compressed gas. In addition, in the air compressor for the ship, the space of the ship is limited, so the volume requirement of the air compressor can be more compact.

The problems to be solved by the invention are as follows: the volume of the air compressor is more compact.
In order to solve the problems, the invention adopts the following scheme:
a cylinder cover with water-cooling compressed air is used for being installed on a cylinder of an air compressor and is provided with a bottom surface sealed with the cylinder, and an air inlet channel, an air outlet channel and a cold water cavity are arranged in the cylinder cover; the air inlet channel is of a cylindrical structure, is vertically arranged in the center of the cylinder cover and is communicated up and down; the bottom edge is provided with an annular sealing mechanism; the inner air port is annular along the outer edge of the sealing mechanism; the outer edge of the inner air port is an annular sealing panel; the sealing panel is used for sealing with the top surface of the cylinder; the outer side of the sealing panel is provided with an arc-shaped air receiving port; the inner air port is communicated with the air receiving port through an air outlet channel; the sealing mechanism is used for pressing the combined air valve and separating the air inlet and the air outlet of the combined air valve, so that the air inlet of the combined air valve is connected with the air inlet channel, and the air outlet of the combined air valve is connected with the air outlet channel through the inner air port; the cold water cavity is arranged between the outer wall of the air outlet channel and the outer wall of the cylinder cover and surrounds the air outlet channel.
Furthermore, a clapboard is arranged above the air outlet channel; a cold water cavity is arranged above the clapboard.
Further, the water inlet of the cold water cavity is arranged on the bottom surface of the cylinder cover.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A cylinder head with water cooling compressed air, as shown in figure 1, figure 2, figure 3, figure 4, figure 5, figure 6, is a square box with a top surface 49 and a bottom surface 48 for mounting on and sealing the piston cavity of the cylinder of the air compressor, in which an inlet channel 41, an outlet channel 42 and a cold water cavity 43 are arranged. Wherein the bottom surface 48 is the interface with the cylinder seal. The air inlet channel 41 is used for air inlet of a piston cavity of the air cylinder, is of a cylindrical structure, is vertically arranged in the center of the air cylinder cover, and is communicated up and down. The air inlet channel is vertically communicated, namely the top opening and the bottom opening of the air inlet channel 41 are formed, wherein the top opening of the air inlet channel 41 is communicated with the outside through an air filter, and the bottom opening of the air inlet channel 41 is arranged on the bottom surface and is communicated with a piston cavity of a cylinder through a combined air valve. The bottom edge of the inlet 41 is provided with an annular sealing mechanism 411. An annular inner air port 421 is arranged along the outer edge of the sealing mechanism 411, and the inner air port 421 is communicated with the air outlet channel 42. When the bottom surface of the cylinder cover is installed on the cylinder, the sealing mechanism 411 is pressed on the combined air valve at the top of the piston cavity of the cylinder, and the air inlet and the air outlet of the combined air valve are separated, so that the air inlet of the combined air valve is connected with the air inlet channel 41, and the air outlet of the combined air valve is connected with the air outlet channel 42 through the inner air port 421. That is, the sealing mechanism 411 seals the combined air valve, so that the air inlet channel 41 and the air outlet channel 42 are isolated and not communicated, and the air inlet channel 41 and the air outlet channel 42 are respectively communicated with the air inlet and the air outlet of the combined air valve. The combined air valve consists of two one-way valves. One of the one-way valves is arranged between the piston cavity and the air inlet of the combined air valve and controls air inlet, so that air can only enter the piston cavity of the cylinder from the air inlet; and the other one-way valve is arranged between the air outlet of the cylinder piston cavity and the combined air valve and controls air outlet, so that air in the piston cavity can only flow out through the air outlet. The outer edge of the inner closure 421 is an annular sealing panel 429. The outside of the sealing panel 429 is provided with an arcuate air receiving port 422. The air receiving port 422 communicates with the air outlet passage 42. The sealing panel 429 is annular and is adapted to seal against the top surface of the cylinder and has an inner diameter matching the diameter of the top opening of the piston chamber of the cylinder to seal the piston chamber of the cylinder. Therefore, air enters the piston cavity of the cylinder from the air inlet 41 through the combined air valve, after being compressed by the piston, the compressed air enters the air outlet 42 from the air outlet of the combined air valve through the inner air port 421, and then is exhausted from the air inlet 422. The cold water cavity 43 is disposed between the outer wall of the air outlet passage 42 and the outer wall of the cylinder head, and surrounds the air outlet passage 42. Above the outlet channel 42 is a baffle 423. Above the partition 423 is a cold water chamber 43. That is, the periphery of the whole air outlet channel 42 is within the range of the cold water cavity 43 except the bottom surface. The inlet 432 of the cold water chamber 43 is provided in the bottom surface 48 of the cylinder head. The water outlet 431 of the cold water chamber 43 is provided at a side of the cylinder head. The structure composed of the air inlet channel 41, the air outlet channel 42, the cold water cavity 43, the sealing mechanism 411, the inner air port 421, the air connecting port 422, the water inlet 432 and the water outlet 431 of the cylinder cover is formed by integral casting.
As can be seen from the above, the sealing mechanism 411, the inner air port 421, the sealing panel 429, the air inlet 422 and the water inlet 432 are all located on the bottom surface 48 of the cylinder head, and the bottom surface 48 of the cylinder head is the interface sealed with the cylinder. Therefore, the compressed air coming out of the air receiving opening 422 finally enters the cylinder box body, the compressed air is cooled by the cold water cavity in the cylinder box body, and the cold water cavity in the cylinder box body is communicated with the cold water cavity 43 of the cylinder cover through the water inlet 432, so that the cooling water can flow into the cold water cavity 43 of the cylinder cover from the cold water cavity in the cylinder box body, and the efficiency of the cooling water is improved.
