Detailed Description

The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.

Example (b):

an oil-gas separator is mounted in a manner shown in figure 1, is structurally mounted on an automobile, and belongs to the technical field of automobile parts. The energy of the engine of the automobile mainly comes from chemical energy of gasoline and is converted into kinetic energy by the engine, mixed gas mainly comprises air, unburned gasoline, hydrocarbon and engine oil, and the mixed gas dilutes the engine oil, so that the engine oil is accelerated to deteriorate, oil sludge is formed, and an oil way is blocked; acid gas in the mixed gas can corrode engine parts and accelerate the abrasion of the parts; if the mixed gas directly enters the cylinder to be combusted, the consumption of the engine oil is large. Therefore, the application of the oil-gas separator can effectively prolong the service life of the engine.

Oil and gas separator includes base 1, shell 2 and lid 3, and the edge of base 1 passes through screw 4 fixed mounting on the engine part of car, and in the prior art, also all can set up oil and gas separator to the engine part. However, the present solution is different from the following, in that the housing 2 is fixed on the base 1 by screws 4, and the base 1 and the housing 2 are combined to form an inner cavity. As shown in fig. 1 and 2, the inner chamber includes a first chamber 51 disposed at the bottom, an air inlet 52, a baffle chamber 53, a funnel chamber 54, and a check valve chamber 6.

As will be understood with reference to fig. 1 and 2, the air inlet 52 is located on the base 1 and communicates with the baffle chamber 53, the air inlet 52 enters directly from the bottom of the base 1, and a plurality of baffle members 531 are fixedly attached to the inside of the baffle chamber 53 and then reach the positions of the baffle members 531. At this moment, oil gas collision baffle, part fluid can be along with the effect of blockking of baffle and gather on base 1, is provided with the passageway of fuel feeding liquid backward flow on base 1, also is the backward flow chamber, is base 1's the back in fact and returns oil chamber 7 promptly to can let fluid enter into base 1's the back. The front and back of the base 1 are referenced to the front illustrated with reference to fig. 2. Similarly, the baffle chamber 53, the funnel chamber 54, and the check valve chamber 6 are all the same.

As can be known from fig. 2, the baffle chamber 53 communicates with the funnel chamber 54, a plurality of funnel structures 541 are arranged in the funnel chamber 54, the funnel structures 541 can further perform vortex separation on oil gas, oil sinks through the funnel structures 541 and leads to the back of the base 1, and the oil gas further enters the position of the check valve assembly 61.

The funnel cavity 54 is communicated with the one-way valve cavity 6, the one-way valve component 61 is arranged in the one-way valve cavity 6, and the air outlet pipe 21 and the air supplement pipe 22 are arranged at the communication position of the one-way valve cavity 6 of the shell 2. To balance the problem of imbalance of air pressure on the operation of the check valve assembly 61, therefore, the outlet pipe 21 and the air supplement pipe 22 are located opposite to each other and at the outlet position of the check valve assembly 61.

As can be understood from fig. 2 and 3, the oil and gas are further separated and enter the check valve chamber 6. Because the effect of check valve subassembly 61 lets oil gas one-way discharge, and oil gas is directly discharged from outlet duct 21 through check valve subassembly 61 promptly to the effect of moisturizing pipe 22 is the action of balanced check valve, makes atmospheric pressure keep balance, makes oil gas normally discharge from outlet duct 21, and lets fluid realize further backward flow through check valve subassembly 61.

Specifically, in conjunction with fig. 2 and 3, the one-way valve assembly 61 includes a valve cover 611, a valve chip 612, a valve body 613, and a filter plate 614. The valve body 613 is provided with a vent pipe in the middle, the upper end of the vent pipe is attached to the valve chip 612, the valve chip 612 has elasticity and is arranged between the valve body 613 and the valve cover 611, the valve cover 611 is fixedly connected to the valve body 613 and enables the valve chip 612 to close the vent pipe through a spring, and the filter plate 614 is arranged at the other end of the vent pipe. The filter plate 614 is provided with a filter portion, and a plurality of filter holes 6141 are distributed on the filter portion. The base 1 is provided with an oil return cavity 7, and the baffle cavity 53, the funnel cavity 54 and the one-way valve cavity 6 are communicated with the oil return cavity 7.

The check valve assembly 61 works in such a way that oil and gas enter the check valve chamber 6 from the funnel chamber 54, and then due to the gas pressure, the valve plate 612 is pushed open, so that the valve plate 612 cannot shield the vent pipe, and the oil and gas enter the back side of the valve body 613 through the vent pipe 23, so that the oil and gas are filtered again through the filter plate 614, and the oil and gas enter the base 1 and enter the back side of the base 1, namely the return chamber. The air passes through the filter plate 614 and is then discharged to the air outlet 21, and the air supply pipe 22 can supply a part of air to balance the air pressure inside the check valve assembly 61, thereby improving the service life and reliability.

In conclusion, the oil gas is filtered and separated for many times by utilizing the multi-step filtering for many times, and finally, the oil can be collected and recycled, so that the energy is saved, the use reliability is improved, and the service life is prolonged.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
