Fluid pressurizing machine

Abstract

The invention discloses a fluid pressurizing machine, which comprises barrel-type cylinder bodies, pistons and at least two reversing fluid valves and is characterized in that: at least one end of each reversing fluid valve is provided with the barrel-type cylinder bodies; each barrel-type cylinder body is provided with a piston and an actuating chamber; the pistons in the barrel-type cylinder bodies are connected with one another through piston rods; each reversing fluid valve is provided with a power fluid inlet and a power fluid outlet and is also provided with a control signal port which is connected with the power fluid inlet or the power fluid outlet; and control signal ports are communicated with the actuating chambers of the barrel-type cylinder bodies. The machine has the advantages of realizing the same function, along with simple structure, low cost, strong function, reliability of operation and long service life.

Description

technical field [0001] The invention relates to a fluid booster, in particular to a fluid booster which is powered by gas or liquid and is suitable for high pressure or super high pressure. Background technique [0002] Traditional fluid pressurization uses purely mechanical push-push plunger method or single-stage pressurization uses two different piston areas similar to the Pascal principle of a jack. The pressurization is limited by the single-stage compression ratio to produce a high-pressure or ultra-high-pressure fluid pressurization. It is difficult to achieve. Other reciprocating booster reversing controls use a trigger mechanism similar to a travel switch. The setting of multiple links is likely to cause reliability problems and complex structures. Traditional fluid reversing control valves usually use cylindrical movement along the axis to switch It is difficult to realize the structural characteristics of the control valve by using double spools or more spools in ...

[0002] Traditional fluid pressurization uses purely mechanical push-push plunger method or single-stage pressurization uses two different piston areas similar to the Pascal principle of a jack. The pressurization is limited by the single-stage compression ratio to produce a high-pressure or ultra-high-pressure fluid pressurization. It is difficult to achieve. Other reciprocating booster reversing controls use a trigger mechanism similar to a travel switch. The setting of multiple links is likely to cause reliability problems and complex structures. Traditional fluid reversing control valves usually use cylindrical movement along the axis to switch It is difficult to realize the structural characteristics of the control valve by using double spools or more spools in the same valve body to increase the control fluid flow rate. At the same time, it is difficult to use a cylindrical control valve that moves along the axis to switch between high and low pressure. Zone sealing only relies on simple valve sealing rings, which has poor bearing capacity for high-pressure fluids. In addition, the entire valve uses a large amount of sealing rings. There are at least two sealing rings in any high-low pressure zone. In this order, a single valve core must have a series of sealing rings. If one of the sealing rings is damaged, it will affect the overall sealing. Secondly, the above-mentioned gas or liquid control valves have very high requirements on the cleanliness of the controlled gas or liquid medium, and even many series of auxiliary equipment need to be added for this purpose. High cost, poor sealing performance, and directly affect product life and performance
