Embodiment 1

[0028] This embodiment is a hydraulic air compressor, such as figure 1 shown. This embodiment includes: a pipe body 1 composed of a horizontal pipe 101 and a vertical pipe 102 connected in an inverted T shape with the horizontal pipe. One end of the horizontal pipe is connected to the water source 3 with potential energy through the water inlet pipe 2, and the other end It is connected with the water outlet pipe 5 provided with the power valve 4, the bottom end of the vertical pipe is connected with the horizontal pipe, and the top is connected with the cylinder 7 through the pulse valve 6, and the side wall near the position of the pulse valve on the vertical pipe is An air intake valve 8 is provided, a drain pipe 9 is provided near the bottom of the cylinder, a drain valve 10 is provided on the drain pipe, a compressed air output pipe 11 is provided on the top of the cylinder, and the compressed air An output control valve 12 is provided on the output pipe.

[0029] The hy...

Embodiment 2

[0041] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding the drain valve. The drain valve described in this embodiment is a differential pressure control valve, and a pressure gauge 901 is set on the drain pipe, such as figure 2 shown.

[0042] The differential pressure control valve described in this embodiment means that the disc opens only under a certain pressure, so the differential pressure control valve is a valve with control pressure, so it is also called a pressure control valve.

[0043] The differential pressure control valve is a special one-way check valve. The opening force of the disc of this one-way check valve can be adjusted. That is to say, since the fluid pressure on one side of the valve can be adjusted, in this embodiment In, is to adjust the pressure in the cylinder.

[0044] The pressure gauge installed on the drain pipe is the pressure on the cylinder side of the differential pressure c...

Embodiment 3

[0046] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment regarding the power valve. The power valve described in this embodiment is a normally open one-way check valve.

[0047] The one-way check valve described in this embodiment is in a normally open state in a free state, that is, in the absence of external force, the valve disc and the valve seat are separated, and the fluid can pass through the gap between the valve disc and the valve seat. void flow. The free state of the valve clack can be in a normally open state under the action of gravity, or it can be in a normally open state under the action of a spring. If the valve clack moves up and down and the valve clack is under the valve seat, then in the free state, the valve clack is separated from the valve seat by gravity, that is, the normally open state. To simplify the system, it is ideal to use a normally open valve without a spring.

Abstract

The invention relates to a hydraulic air compressor and a method. The compressor comprises a pipe body formed through a horizontal pipe and a vertical pipe in inverted-T-shaped connection of the horizontal pipe; one end of the horizontal pipe is connected with a water source with potential energy through a water inlet pipe, the other end of the horizontal pipe is connected with a water outlet pipe with a power valve, the bottom of the vertical pipe is connected with the horizontal pipe, the top end of the vertical pipe is connected with an air cylinder through a pulse valve, an air inlet valve is arranged on the side wall, close to the pulse valve, of the vertical pipe, and a draining pipe is arranged at the position, close to the bottom, of the air cylinder. The inverted-T-shaped pipe body and the power valve are used, the water hammer effect is generated, the water hammer effect is used for compressing air, when negative pressure appears, external air is sucked in for supplementing, circulating is carried out, pressurizing is continuously carried out, air is continuously supplied, and a power air source is formed in the air cylinder; the generated power air source is not subject to electric energy conversion, an air power source is directly generated, and the energy conversion efficiency is improved.

Description

technical field [0001] The invention relates to a hydraulic air compressor and a method, which is a mechanical device and a method for converting fluid energy, and a device and a method for converting the energy of low-head water flow into air compression energy. Background technique [0002] Low-drop and micro-hydraulic energy resources are common in nature, how to make full use of this resource has always been a difficult problem in the engineering field. The traditional way of using hydraulic resources is to impact the rotating machinery with low-drop water flow, convert the low-drop water energy into rotating mechanical energy, drive the traditional generator to generate electricity, and then convert the electrical energy into mechanical energy to produce various functions, such as driving vehicles, pumping water, and compressing air etc. There are many energy conversion processes, and each conversion will lose some energy. The energy of low-drop micro-hydro energy res...
