Abstract

The utility model provides a two-way parallel filtering device, which belongs to a filtering device used on an engine. The filtering device is provided with an inlet pipe and a total inlet pipe which are communicated together, wherein one filter is installed on the inlet pipe; one outlet pipe is connected behind the filter. The two-way parallel filtering device is also provided with the other inlet pipe connected in parallel to the inlet pipe; the other filter is installed on the other inlet pipe; the other outlet pipe is connected behind the other filter; the other outlet pipe and the outlet pipe are connected in parallel to a total outlet pipe. Parallel parts of the inlet pipes or parallel parts of the outlet pipes are provided with transfer switches. The two-way parallel filtering device can be respectively used on air passages, fuel oil passages and machine oil passages, and can be conveniently replaced with the other filter to filter inlet air and inlet oil after certain filter is dirty or is damaged through the transfer switches. Consequently, the problems that the fuel oil supply is not smooth; the machine oil pressure is insufficient; the abrasion of a friction pair of the engine is pricked up, etc. are avoided after single filter is dirty or is damaged; the service life of the engine is prolonged.

Description

A kind of two-way parallel filtering device

Technical field

The utility model provides filtrating equipment, especially a kind of filtrating equipment that is used on the motor.

Background technique

At present, on the gas circuit of motor, fuel path, engine oil passage, a filter only is set respectively usually.Like this, after this filter stops up, damages because of long-term use, can bring adverse consequences.After damaging as the filter on the fuel path, the impurity in the fuel oil can cause oil circuit to stop up, and causes fuel feeding not smooth, even can not fuel feeding, makes Motor Vehicle bad on the way.As the filter on the engine oil passage dirty after, can cause the charge oil pressure deficiency, each lubricant housings insufficient lubrication, aggravation wearing and tearing.As the filter on the gas circuit dirty after, can make in the air inlet of motor and contain dust impurity, cause the friction pair wearing and tearing aggravation of forming by piston, piston ring, cylinder barrel, the working life of reducing motor.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of two-way parallel filtering device is provided, it can be therein on the way filter with dirty or damage after, use in addition filter on the way easily instead.

The utility model is to realize like this, a kind of two-way parallel filtering device, it has inlet pipe and total inlet pipe to be connected together, filter is installed on the inlet pipe, and the filter back is connected with out pipe, and it is attempted by another inlet pipe on the inlet pipe in addition, another filter is installed on another inlet pipe, another filter back is connected with another and goes out pipe, and another goes out pipe and goes out pipe and be attempted by always to go out on the pipe, in the joint of each inlet pipe or the joint that respectively goes out pipe throw over switch is installed.

Adopt the two-way parallel filtering device of said structure, can be used on gas circuit, fuel path, the engine oil passage respectively, pass through throw over switch, can be easily therein a certain filter with dirty or damage after, using another filter instead filters air inlet, oil-feed, thereby after having avoided single filter with dirty or damage, fuel feed is not smooth, engine oil pressure is not enough, and problem such as the friction pair of motor wearing and tearing aggravation, reduce maintenance, the maintenance frequency of motor, prolonged the working life of motor.

Description of drawings

Fig. 1 is the schematic representation of the utility model structure.

Fig. 2 is the schematic representation of a kind of structure of the throw over switch in the utility model.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and working principle.

As shown in drawings, a kind of two-way parallel filtering device of the utility model, it has inlet pipe (2) and total inlet pipe (1) to be connected together, filter (3) is installed on the inlet pipe, the filter back is connected with out pipe (5), it is attempted by another inlet pipe (12) on the inlet pipe in addition, another filter (11) is installed on another inlet pipe, another filter back is connected with another and goes out pipe (9), another goes out pipe and is attempted by always to go out on the pipe (7) with going out pipe, in the joint of each inlet pipe or the joint that respectively goes out pipe throw over switch (6) is installed.

Also have the 3rd filter (4) in the back of described filter (3), also have the 4th filter (10) in the back of another filter (11).This is the filtrating equipment on a kind of fuel path that is used for diesel engine.Fuel oil from total inlet pipe enter, when always going out pipe and come out, passed through double-filtration.

When being used on the gas circuit, total inlet pipe is connected with ambient atmosphere, always goes out pipe and is connected with the suction tude of motor, and filter is an air-strainer.When being used on the fuel path, total inlet pipe is connected with fuel tank, always goes out pipe and is connected with the motor injection system, and filter is a fuel oil fitering element.When being used on the engine oil passage, total inlet pipe is connected with the oil pump that is arranged in oil sump, always goes out pipe and is connected with oil leab, and filter is a machine oil filter core.

Throw over switch can be installed in the joint of each inlet pipe, also can be installed in the joint that respectively goes out pipe.Throw over switch among the figure is installed in the joint that respectively goes out pipe.In throw over switch, being fixed with outward edge in the rotating shaft (14) is the stifled logical device (13) of arc, and the end face that respectively goes out pipe also is arc.By rotating the knob (8) that is fixed together with rotating shaft, driving stifled logical device turns an angle, can block one of them and go out pipe, be on state and make another go out pipe, promptly realized therein one tunnel filter with dirty or damage after, use in addition the purpose that filter on the way filters air inlet, oil-feed instead.Obviously, throw over switch also can adopt other structural type.

Throw over switch can directly rotate with hand, also can be by anchoring in its rotation of operator cabin inner control.

Claims

1, a kind of two-way parallel filtering device, it is characterized in that, it has inlet pipe (2) and total inlet pipe (1) to be connected together, filter (3) is installed on the inlet pipe, the filter back is connected with out pipe (5), it is attempted by another inlet pipe (12) on the inlet pipe in addition, another filter (11) is installed on another inlet pipe, another filter back is connected with another and goes out pipe (9), another goes out pipe and is attempted by always to go out on the pipe (7) with going out pipe, in the joint of each inlet pipe or the joint that respectively goes out pipe throw over switch (6) is installed.

2, a kind of two-way parallel filtering device as claimed in claim 1 is characterized in that also having the 3rd filter (4) in the back of described filter (3), also has the 4th filter (10) in the back of another filter (11).
