Abstract
The invention provides a silencing and energy-saving type pressure increasing valve with long service life, relating to a pressure increasing valve which has the advantages of energy conservation, silencing and long service life. The pressure increasing valve adopts a secondary air cylinder mechanism, and a piston of a large air cylinder is used for driving a piston of a small air cylinder and pressurizing compressed air. When secondary side outlet pressure is less than primary side inlet pressure, under the function of a pneumatic reversing valve, the compressed air does not need to drive the piston to apply work and is directly discharged from a secondary side outlet through a check valve, so the pressure increasing valve has the effect of energy conservation. The invention adopts the pneumatic reversing valve to control the air cylinders, and the cylinder wall of the large air cylinder is provided with four pneumatic holes; when the piston of the big air cylinder does not move to a stroke end (does not touch the end cover of the big air cylinder), the pneumatic reversing valve shifts, the original exhaust cavity of the large air cylinder is changed into a driving cavity, and the rapidly inflated compressed air plays an air cushion buffering function, the structure avoids bumping the end cover of the big air cylinder and other elements and has silencing effect and long service life.
Description
Technical field:
The invention belongs to pneumatic system energy-saving environmental protection field, relate to the used long life energy-saving mute type booster valve of the local supercharging of pneumatic system.
Background technique:
In pneumatic system, often there is some occasion to need a small amount of, partial high pressure gas.For example: indivedual or partial devices need be used high pressure in the gas circuit; Because remote gas transmission or gas leakage cause main gas circuit pressure to descend, and can not guarantee the minimum working pressure of Pneumatic actuator; The space is narrow, can not dispose the heavy caliber cylinder, but ouput force is must guarantee again the time; Or the like.Solve this type of problem, what adopt usually at present is local supercharge method, and it is to utilize pressure charging valve to obtain pressurized gas, can save cost, reduce bleed pressure, especially pneumatic system is carried out reducing energy consumption, and its effect is more outstanding.
The big cylinder piston actuated of the simultaneous small cylinder piston acting of pressure charging valve second side outlet exhaust both domestic and external now.Can learn according to the pneumatic power notion, each working procedure of pressure charging valve all can have a large amount of pressurized air expansion energy losses in the actuator chamber, energy utilization rate is not high, especially when the pressure of pressure charging valve first side during, more can cause unnecessary energy loss greater than the pressure of second side.Pressure charging valve relies on the piston slap selector valve to realize commutation, so can produce strong vibrations and noise, and working life is short.The today that become increasingly conspicuous in energy problem, environmental problem receives much concern, energy-saving mute type booster valve has an important significance to energy-saving and cost-reducing, the environmental improvement of pneumatic industry.
Summary of the invention:
Purpose of the present invention: the objective of the invention is to overcome the deficiency in traditional pressurized cylinder and a kind of novel long life energy-saving mute pressure charging valve is provided.
Technological scheme of the present invention: the objective of the invention is to reach by following measure.A kind of novel energy-saving mute pressure charging valve is mainly formed (referring to Fig. 1) by one-way valve, cylinder body, pressure regulator valve, Pneumatic reversal valve, piston etc.
Energy-saving principle: the pressure charging valve secondary is surveyed with gas holder and is joined in the use, and inflation is divided into gas holder pressure and is lower than and is higher than two stages of measuring pressure of pressure charging valve gas to gas holder by pressure charging valve.Incipient stage gas holder pressure is lower than measuring pressure of pressure charging valve, be that pressure charging valve second side outlet pressure is less than the first side inlet pressure, pressurized air does not need the driven plunger acting that air in the booster cavity is compressed, and directly through one-way valve, discharge from the second side outlet, avoid the compressed-air actuated loss that causes to the actuator chamber inflation.
The principle of quiet, the long lifetime effect of pressure charging valve: on big cylinder casing wall, having four gas control mouths, at piston during not to stroke terminal when (not running into cylinder end piece), the Pneumatic reversal valve displacement, the former exhaust cavity of cylinder becomes actuator chamber, the pressurized air that charges into rapidly plays the effect of air cushion buffering, and piston can percussion piston end cap and other components and parts.
Embodiment:
When second side outlet pressure during less than the first side inlet pressure, Pneumatic reversal valve A puts upper, and pressurized air is inflated to second side through one-way valve.
When second side outlet pressure during near the first side inlet pressure, Pneumatic reversal valve A deposits the position, the pressurized gas of input divides two-way, one tunnel process one-way valve charges into the A of pumping chamber and the B of little cylinder, another road is inflated actuator chamber B exhaust through Pneumatic reversal valve A, pressure regulator valve and Pneumatic reversal valve C to the actuator chamber A of big cylinder.Big piston moves to right like this, drives small piston and also moves to right, and stingy cylinder booster cavity B supercharging is discharged pressurized gas from the second side outlet; When piston moves between gas control mouth C, the D, right respectively position of Pneumatic reversal valve C, D and position, a left side, then actuator chamber B inflation, Pneumatic reversal valve D resets, actuator chamber A exhaust, the big piston reversing motion, booster cavity A supercharging, the second side outlet continues to get rid of pressurized gas.More than action is carried out repeatedly, just the pressurized gas that can be exported continuously from outlet.Outlet pressure feeds back to pressure regulator valve, can make outlet pressure remain on a certain value automatically.When needs changed outlet pressure, the can regulate handwheel just can obtain the outlet pressure of any setting in the pressure ratio scope.
Advantage of the present invention is: compare with existing pressure charging valve, energy-saving mute type booster valve can be saved Compressed air, reduction vibration and noise increase the service life.
