Description

The compressor outlet valve assembly

Technical field

The utility model relates to the technical field of air compressor, refers to a kind of outlet valve assembly of compressor especially.

Background technique

The running of general air compressor, be after outside air is filtered via air-strainer, via suction valve input compressor block, after the compressor block compression, in the thin separator of oil return check valve input oil, oil is separated with high-pressure liquid, make Oil-gas Separation to a barrel of oil and gas, provide lubrication in the compressor block to reenter, store in the middle of being delivered to air reservoir and keep valve with the fluid of Oil-gas Separation by a pressure, this pressure is kept the pressure that valve can be set unlatching, when air pressure arrives default value, promptly can push the valve block that pressure is kept valve open, in the input air reservoir.

Yet thin separator of existing oil and pressure are kept valve and are designed for separated type, see through a pipeline between the two and connect, and so design has following several disappearances at least:

1. because therefore it need, under limited installing space, have to dwindle the volume that thin separator of oil and pressure are kept valve than large space, cause efficient relatively poor.

2. because the thin separator of oil is kept between the valve and need be connected with pipeline with pressure, and pipe arrangement has the problem of leakage unavoidably, cause maintenance cost to increase.

3. the thin separator of oil and pressure are kept valve and are connected via pipeline and promptly produce pressure drop, reduce compressed-air actuated efficient.

The model utility content

In order to improve above-mentioned disappearance, main purpose of the present utility model is to provide a kind of and exempts from pipe arrangement, reduces the compressor outlet valve assembly that leaks chance, reduces pressure drop.

Based on above-mentioned purpose, major technique means of the present utility model comprise:

The thin separator base of one oil, comprise a fixed edge, be located at fixed edge wherein the ring seat, of an end be located at the extending seat that interior ring seat in the ring seat scope, is extended towards outer radial by the ring seat periphery wall, wherein, be provided with the intake duct of always wearing fixed edge between outer ring seat and the ring seat, interior ring seat center is provided with a gas transmission road, this extending seat is inner to be communicated with the gas transmission road, and be provided with a valve port in the inner stage casing of extending seat, on the perisporium between valve port and the extending seat free end, be provided with the air outlet channel that one day, outer radial extended;

The thin separator of one oil, comprising that a cover cap, that is incorporated into the ring seat end face is positioned at cover cap and is connected in the careful pipe of the oil in gas transmission road, is sheathed on oil careful pipe outside and is incorporated into the filter screen of ring seat end face, wherein, the careful tube hub of this oil is provided with a through hole that runs through two ends;

One pressure is kept valve assembly, comprises that one is incorporated into the free-ended sleeve valve seat of extending seat, and is screwed together in piston seat, that the sleeve valve seat is sheathed on this end of sleeve valve seat proximate valves mouth away from the regulator bolts, of this end of the thin separator base of oil and is sheathed on the piston seat and the valve block, that can seal valve port is located at spring, between valve block and the piston seat and is stayed on pressure adjusting spring between piston seat and the regulator bolts.

Described compressor outlet valve assembly, wherein, described sleeve valve seat and extending seat screw togather mutually.

Described compressor outlet valve assembly, wherein, the careful pipe of described oil screws togather mutually with the gas transmission road.

Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is:

Since the utility model on the thin separator base of oil, install simultaneously the thin separator of oil, and pressure keep valve assembly, can effectively dwindle installing space, in other words, under existing space, it is bigger to utilize the utility model size can be made as, to improve the oil segmentation from efficient.

2. the thin separator of oil of the present utility model is kept between the valve assembly with pressure and need be connected with pipeline, can save the installation time.

3. by design of the present utility model, after making that the fluid of oily separates via the filter screen of the thin separator of oil inside, input gas transmission road, when being accumulate to predetermined pressure, push the valve block of valve port open, by air outlet channel output, because keeping between the valve assembly, need not carry thin separator to the pressure of oil by external pipeline, can avoid losing heart or producing pressure drop by the pipeline joining place.
