Description
Technical field
The utility model relates to a kind of compressor part, the blowdown valve that uses on especially a kind of compressor, specifically a kind of gas control blowdown valve system.
Background technique
As everyone knows, High-Pressure Compressor can produce a large amount of condensed waters in the process of pressurized gas.If untimely eliminating, a large amount of condensed waters are inhaled into the next stage cylinder, can produce " liquid hammer " phenomenon.In case important spare parts such as " liquid hammer " meeting major injury air valve, piston, connecting rod take place.In addition, compressor stops, when starting, pressurized gas in the compression chamber and the rapid emptying of the condensed water in the knockout drum must reached the purpose of No Load Start.If drainage has problem, slow as blowdown speed, even stop up, can cause band to carry and start, produce " vexed car " even burn out motor.Therefore, the reliability of drainage directly influences the safe operation of high pressure compressor.
For the blowdown valve of minitype high voltage air compressor, adopt the electromagnetism blowdown valve usually, owing to be subjected to the restriction of volume and electromagnetic force, the latus rectum of high pressure electromagnetism blowdown valve is done very for a short time usually, blowdown speed is slow, blocks easily.And spool also will often be pulled down cleaning.Some foreign brands adopts the gas control blowdown valve, though the too little problem of latus rectum solved, complex structure, the rate of fault height, using effect is undesirable.
Summary of the invention
The purpose of this utility model is that too little or gas control pollution discharge structure is too complicated at existing minitype high voltage air compressor electromagnetism blowdown valve latus rectum, the blowdown that exists is not smooth, and susceptible to plugging problem designs a kind of simple in structure, reliable operation, the gas control blowdown valve that the blowdown latus rectum is big.
The technical solution of the utility model is:
A kind of gas control blowdown valve system comprises blowdown valve and pilot-actuated valve, and aperture stream valve.It is characterized in that described blowdown valve comprises valve body, piston valve core and valve gap, valve body is provided with dirt inlet and sewage draining exit, the drain outlet connects dirt inlet and sewage draining exit, the taper of spool one end can be controlled the break-make of drain outlet, the other end of spool is piston structure, this piston structure is arranged in the cylinder of valve body, directly or by the gas control interface on the valve gap communicates with the gas circuit of pilot-actuated valve.
The suction port of described pilot-actuated valve is connected with the gas control interface, and the pipeline node links to each other with higher level's pressure gas source, the one or more orifice restriction valves of series connection on its pipeline.
Described spool has the drain outlet that can block under the pressed gas promotion between dirt inlet-sewage draining exit by piston structure at the gas control interface.When gas control interface gas pressure disappeared, the pressurized gas in the dirt inlet chamber push spool open and piston structure makes the passage between dirt inlet-sewage draining exit open-minded.
The beneficial effects of the utility model:
The latus rectum of blowdown valve of the present utility model can design greatlyyer, does not have the sorrow of obstruction, and blowdown rapidly, thoroughly, reliably.
The utility model is simple in structure, owing to adopt air pressure control, the gas control active force is big, does not have the danger of obstruction, does not need frequent cleaning, the reliability height.
The utility model is because blowdown is rapid, thorough, reliability is high, cost is low, not only can be used for High-Pressure Compressor, improve the high-pressure unit operational reliability, for other compressed air system that a large amount of condensed waters dischargings are arranged (as compressed air purification system etc.) high using value is arranged also simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of gas control blowdown valve system comprises blowdown valve I, pilot-actuated valve II and orifice restriction valve III.Described blowdown valve I comprises valve body 1, spool 6 and valve gap 4.Valve body 1 is provided with dirt inlet A and sewage draining exit B.Connected by the drain outlet between dirt inlet A, the sewage draining exit B, spool 6 can be controlled the passage break-make of blowdown between dirt inlet A, the sewage draining exit B.The tapered structure of one end of spool 6, the other end of spool 6 is piston structure 5, and this piston structure 5 is arranged in the atmospheric pressure cavity of valve body 1; This atmospheric pressure cavity directly or by the gas control interface C on the valve gap 4 communicates with the gas circuit of pilot-actuated valve II.Install the seal ring of O type or other form on piston structure 5 and the spool 6 additional.Pilot-actuated valve II can adopt structure shown in Figure 1 or similar solenoid valve.Get a node in pilot-actuated valve II suction port and the gas control interface C connecting pipeline and link to each other, the one or more orifice restriction valve III of series connection on its connecting pipeline with higher level's pressure gas source.During concrete enforcement, for a person skilled in the art, pilot-actuated valve also can adopt other similar equivalent function structure, no matter but adopt which kind of structure, so long as the pilot valve or the equivalent structure of pilot pressure are provided for blowdown valve, all be considered to equivalence of the present utility model and replace, covered among the utility model.
Working principle of the present utility model:
The utility model two-bit triplet blowdown valve has three interfaces: dirt inlet A, sewage draining exit B, gas control interface C.Behind gas control interface C cut-in pressure gas, promote piston structure 5, spool 6, with inner passage sealing between dirt inlet A, the sewage draining exit B.Because the diameter D of piston is greater than passage aperture d, as long as satisfy following formula:
(D
2π/4)P
C＞(d
2π/4)P
A
Just the blocking-up that can guarantee the valve passage hole ends.P in the formula
CBe control air pressure, P
AHigh pressure (common P for dirt inlet
C＜＜P
A).If control air pressure P
CDisappear P
APiston (spool) is pushed open blowdown rapidly.
Gas control blowdown valve I combination in parallel with pilot-actuated valve II.The suction port of pilot-actuated valve II is connected nearby with the gas control interface C of gas control blowdown valve I, gets the air outlet of a node and previous stage in the middle of its connecting tube and connect.And the orifice restriction valve III that in adapter, connects.After guide's control valve II coil electricity was opened, the pressed gas in the Pneumatic valve control cylinder discharged rapidly through solenoid valve, and from the control air-flow of prime output because of being subjected to the damping of orifice restriction valve III, be not enough to replenish.Therefore, the rapid decompression of air pressure in the control cylinder, the pressurized gas of dirt inlet A are pushed piston valve core 6 open, carry sewage and discharge rapidly.After guide's control valve II electromagnetic coil outage, pilot-actuated valve II ends, and enters the gas control chamber from the pressed gas of prime output through gas control interface C and promotes piston structure 5 and spool 6 and close passage between dirt inlet A, the sewage draining exit B.
Match as pilot-actuated valve with the damping function of orifice restriction valve with electromagnetic release valve, simultaneously at P
A(high pressure) effect down, control gas control blowdown valve piston valve core open/close action.Its mechanism is as follows: P
C(control air pressure) foundation → blowdown valve cuts out; P
CDisappearance → P
A(high pressure) pushes spool open, blowdown.
Lead to/closing of blowdown valve is controlled by the "on" position of electromagnetic valve coil, and its mechanism is as follows:
I is open-minded for coil electricity → pilot-actuated valve II venting → blowdown valve.
Coil losing electricity → pilot-actuated valve II closes by → blowdown valve I.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
