Description
Technical field
The utility model is related to natural gas engine technical fields, and in particular to a kind of fuel cut-off of integrated filter structure
Valve.
Background technology
The fuel cutoff valve being often used on natural gas engine at present includes two kinds of through type and pilot-operated type, this class A fuel A is cut
Disconnected valve is solenoid valve, and solenoid valve is to generate magnetic force using coil energization excitation, drives valve core movement to open or close to control
The supply of fuel processed, such as high pressure fuel stop valve, low-pressure fuel stop valve.It is with diaphragm type pilot-operated type low-pressure fuel stop valve
Example (refers to QC/T 674-2007《Compressed natural gas for automobile solenoid valve》), the operation principle of fuel cutoff valve is specially：Power-off
When, the input end stream pressure of fuel cutoff valve passes through the micropore inlet membrane top of valve body diaphragm so that input end and diaphragm
Top air pressure having the same, because the forced area above diaphragm is big, valve port can be pushed down by diaphragm, fuel cutoff valve
Valve close, fuel be cut off.When energization, pilot valve is carried by coil, and the pressure above diaphragm is reduced to rapidly
Outlet pressure, diaphragm is open-top by inlet pressure, and valve is opened, and fuel realizes supply.Such fuel cutoff valve is with its degree of regulation
The advantages that high, safe to use, shape is light and handy, is widely used in engine fuel system pipeline.
However, since existing fuel cutoff valve is all to realize combustion by the opening and closing of electromagnetic excitation control cut-out valve core
Material supply, therefore spool as most critical in entire fuel cut-off valve member part and damaged condition and susceptibility most
High part.Due to the usual impurities in fuel cutoff valve upstream, clast that such as rubber tube aging falls off, metal tube
The meetings such as the fine impurities that road, connector are generated due to the metal fillings and sealing material that are generated in installation process due to aging or weathering
It enters in fuel cutoff valve, causes to block inside fuel cutoff valve or exacerbate the degree of wear of spool at work, to
There is dielectric leakage, stop valve is closed the problems such as not tight.Either fuel leakage or fuel cutoff valve control failure, all can shadow
It rings to fuel and conveys the performance for even influencing engine.
The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition has been existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is to provide a kind of fuel cutoff valves of integrated filter structure, to overcome the prior art
Fuel cutoff valve be easy fuel cutoff valve caused by being polluted by foreign matter and impurity that upstream enters leak, clamping stagnation
Disadvantage.
To achieve the above object, the utility model provides a kind of fuel cutoff valve of integrated filter structure, including：Valve
Body, with arrival end；Inlet attack is mounted at the arrival end of valve body；And strainer, valve body can be integrated in
It is interior or be integrated on inlet attack.
In a preferred embodiment, when strainer is integrated in valve body, arrival end is provided with the first limited step,
Strainer is installed in an interference fit on the first limited step, and the end face of inlet attack is against on the end face of strainer, with
Prevent strainer from loosening or moving.
In a preferred embodiment, when strainer is integrated on inlet attack, inlet attack end face is provided with
Two limited steps, strainer are installed on the second limited step, and spacer ring is installed in inlet attack port in an interference fit,
To prevent strainer from falling off.
Compared with prior art, the fuel cutoff valve of integrated filter structure according to the present utility model has following beneficial to effect
Fruit：
Since the fuel cutoff valve of the utility model is integrated with filter structure, it is thus possible to effectively improve fuel cutoff valve
Cleannes, effective protection fuel cutoff valve are not polluted by foreign matter and impurity that upstream enters, to solve thus to cause
Block failure, and then avoid fuel leak and fuel cutoff valve control failure the problems such as.

Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figs. 1-2, according to the fuel cutoff valve of the integrated filter structure of the preferred embodiments of the present invention, packet
It includes：Valve body 1, inlet attack 2 and strainer 3.Wherein, valve body 1 has arrival end.Inlet attack 2 is mounted to the arrival end of valve body 1
Place.Strainer 3 can be integrated in valve body 1 or be integrated on inlet attack 2, to effectively be carried by strainer 3 are arranged
