Abstract

The utility model discloses an explosion-proof type oil, dual-purpose air cleaner box of gas, it includes casing on the filter box, casing under the filter box, filter core support, sealed pad, original air inlet and filtered air gas outlet. The filter box is characterized in that the upper shell and the lower shell of the filter box are made of anti-burst metal materials, the upper shell and the lower shell are connected through hinges to form an opening and closing structure, the upper shell and the lower shell are closed by tension springs, a safety valve with a safety valve cover is mounted on the upper shell, and an adjusting plugboard and a filter screen are arranged at an air inlet. The product has simple structure, convenient use, safety, reliability, gas saving and explosion prevention, and is a renewal product for oil-to-gas automobiles.

Description

A kind of oil, the dual-purpose air cleaner box of vapour

Technical field

The utility model relates to a kind of air-strainer, relates in particular to a kind of automotive field oil, the dual-purpose air cleaner box of vapour.

Background technique

At present; it is to install a cover rock gas isolated plant transformation additional by the automobile that uses gasoline to form that most rock gas, gasoline dual-purpose fuel automobile are arranged; air enters before the motor; usually to remove unnecessary particulate matter and impurity by air-strainer; used air cleaner box mostly is plastic material; the charge flow rate of air can not get effective control; rock gas and air mixing are inhomogeneous; make automobile phenomenons such as cleaner box blast, high pressure electric leakage in enforcement, occur through regular meeting, cause automobile out of service.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, provides a kind of simple in structure, easy to use, safe and reliable, solar term, the explosion-proof dual-purpose air cleaner box of oil, gas.

The purpose of this utility model is to realize like this, a kind of air cleaner box comprises the cleaner box upper shell, the cleaner box lower shell body, filter core, the filter core support, sealing gasket, original air suction port and filtering air air outlet, the original air suction port is positioned at the side of lower shell body, filtering air air outlet is positioned at the side of upper shell, the metallic material of the anti-explosion of the material selection of cleaner box upper shell and lower shell body, last lower shell body adopts the hinge nut, screw is connected to form can open entire structure, with extension spring lower shell body being closed cuts off from, be provided with the filter core support at the cleaner box lower shell body, filter core is installed, and be added with sealing gasket and make the sealing of filter core and last lower shell body better, air-filtering is more abundant, be provided with the stay bolt crossbeam that plays the stay bolt effect that connects two sidewalls simultaneously at the cleaner box lower shell body, avoid mixing air overrich cleaner box body deformability and filter core to sink.

On the cleaner box upper shell Safety valve is housed, Safety valve is to constitute by installing on the Safety valve body with pin and the fixing safe valve gap of torsion spring, and Safety valve body is screwed on the cleaner box upper shell.

The original air suction port place of cleaner box lower shell body is provided with one and regulates plate and filter screen, this filter screen is connected on the lower shell body with pressing plate, screw, nut, being added with filter screen is blocked in outside the suction chamber more airborne impurity, prolonged the working life of filter core, the adjusting plate has been installed is controlled the air inlet.

The utility model filter core horizontal positioned, air-flow blows into suction chamber in the cleaner box lower shell body from original air suction port level, directly do not blow to filter core, can reduce the air velocity by filter core, help improving the dust contaminating rate and the life-span of filter core, air cleaner box is divided into lower shell body, adopting hinge to install connects, and cut off from extension spring envelope, convenient disassembly, more renew cartridge is also convenient.When mixed gas increases owing to what adopt in the filter cleaner inner volume is that the metallic material of anti-explosion and the torsion spring that connects lower shell body have certain cushion effect, make filter cleaner be unlikely to explosion, add the cleaner box upper shell and have Safety valve, can discharge a part of gas by Safety valve when volume of air increases to certain volume, thereby reach explosion-proof and the fuel saving function.

The utility model has following advantage compared with the prior art:

At first,, be connected lower shell body, prevented because the negative effect that the plastics air cleaner box produces automobile at explosion time with torsion spring with buffering owing to adopted the metallic material of anti-explosion to make housing.

Secondly, at upper shell Safety valve has been installed, excessive air is discharged, be unlikely in enforcement because of the mixed gas overrich, the high pressure electric leakage produces blast or waste fuel.

Once more, filter screen is installed at the suction port place and is regulated the adjusting plate of air inlet, the air plankton that enters filter is reduced, the air inlet flow is well controlled, and has increased the working life of filter core, prevents blast.
