Abstract

The utility model relates to the gas engine depressurized wind oil separator, comprising an inlet pipe, an inlet room, a filtering web, an outlet room and an outlet pipe and a wind blow reducing system. In terms of the characteristic, the side wall of the inlet room is provided with a notch where the spring type valve is, and the wind blowing device and the air is communicated outside the valve body. In the notch, the side wall notch of the inlet room is provided with the filtering web. After the oil and gas separator is blocked, the pressure in the gas room elevates, and the spring type valve opens automatically, and the gas flow drives the wind blowing machine to make sounds. Meanwhile, the pressure coming into the inlet room drops, and controls the air and oil separator, and ensures the air and oil separator to exert the expected effect.

Description

The decompression wind ding type deaerator of internal-combustion engine

The utility model belongs to the operation monitoring technical field of internal-combustion engine.

Background technique:

At present the air outlet of the crankcase of some internal-combustion engine connects a gas and oil separating plant, and this device separates the fuel-air mixture body, and this is fuel saving and help environmental protection not to the utmost, and the working life of raising internal-combustion engine.But because the not monitoring of this device, and the filter screen in the deaerator stops up easily; One works as filter screen stops up the effect that does not only have Oil-gas Separation, and exerting oneself of internal-combustion engine reduced greatly, the easy internal-combustion engine that damages of long-time use.The purpose of this utility model relates to the supervisory device of deaerator for this reason, promptly opens a notch at the suction chamber sidewall of deaerator, refills a decompression aeolian attachment, prevents the suction chamber overpressure, wind ring simultaneously.

Technology contents:

The utility model is made up of housing, suction tude, suction chamber, filter screen, discharge chamber, steam outlet pipe and decompression aeolian attachment, and the decompression aeolian attachment is made up of filter screen, spring chip valve and hummer; Have a notch on the sidewall of suction chamber, spring chip valve is housed on notch, this valve is to have tongue and framework to make, and tongue and framework have part affixed, and remaining part is unsettled; The outside of spring chip valve connects a hummer and atmosphere is communicated with; (on the suction chamber inwall) is equipped with filter screen in the notch; After the filter screen in the deaerator stops up, the mixed pressure in the suction chamber will raise, and when the pressure height arrived to a certain degree, spring chip valve was opened automatically, and air-flow is gone out from valve, drive hummer and sound, and reduce the pressure of suction chamber simultaneously; Housing is by each half injection molded up and down, and last half and steam outlet pipe are integral, and time half and suction tude are integral; During installation, filter screen, decompression aeolian attachment are installed, will go up the lower shell body integrator again and get final product; Filter screen is to make cylindrical shape by ventilative oil resistance material to filter web-roll core, is surrounded by wire gaze inside and outside the web-roll core; Filter screen is established in housing suction chamber and discharge chamber is separated.Advantage of the present utility model, simple in structure, be convenient to implement; Both kept all advantages of deaerator,, helped environmental protection, prevented carbon distribution, and improved the internal-combustion engine use and receive the order, simultaneously deaerator had been carried out effective monitoring as fuel saving; Promptly after the filter screen of deaerator stops up, can not influence exerting oneself of internal-combustion engine, reminds people is in time carried out cleaning to deaerator simultaneously, guarantees should producing effect of deaerator.

Description of drawings:

Accompanying drawing 1 is the outline drawing (plan view) of the decompression wind ding type deaerator of internal-combustion engine, and 1 is suction tude among the figure; The 2nd, housing; The 3rd, suction chamber and suction tude 1 are communicated with; The 4th, filter web-roll core, it is to make cylindrical shape by ventilative oil resistance material webs, establishes in housing 2, the upper and lower end of tube withstands the last lower wall in the housing; The 5th, discharge chamber and steam outlet pipe 6 are communicated with; The 7th, the decompression aeolian attachment is positioned on the sidewall notch of suction chamber 3.

Accompanying drawing 2 is sectional views of the decompression wind ding type deaerator of internal-combustion engine, and 1 is suction tude among the figure; The 2nd, housing, this housing be by half and half injection molded up and down, and last half and steam outlet pipe 6 are integral, and time half and suction tude 1 are integral; The 4th, filter web-roll core, be to make cylindrical shape by ventilative oil resistance material, tube places center in the housing, and the upper and lower end of tube withstands the inwall of lower shell body, and suction chamber 3 and discharge chamber 5 are separated; The 8th, the inside and outside wire gaze 5 that filters web-roll core 4 is that discharge chamber and steam outlet pipe 6 are communicated with; The 9th, the filter screen on 7 is adorned in the ring of decompression wind, is contained in the inwall notch place of suction chamber 3; The 10th, spring chip valve, be contained in the notch outside of suction chamber 3, it is made up of tongue and framework, its tongue and frame part are affixed, the 11st, hummer be contained in spring chip valve 10 the outside and and atmosphere connection, under normal barometric pressure (in the suction chamber 3), this valve is not opened, do not have air-flow to go out, hummer 11 is sounding not; Have only the air pressure in the suction chamber 3, when height arrived to a certain degree, this valve was just opened automatically, and air-flows are gone out in the suction chamber 3, drive hummer 11, sound.
