Abstract
The invention relates to the technical field of the use maintenance of the aircraft fuel system, in particular to a stop valve used for an aircraft fuel system. The stop valve used for the aircraft fuel system comprises a valve body, a valve plug and an operation handle, wherein the main body of the valve body is a hollow cylinder; two sides of the main body of the valve body are provided with two hollow cylindrical adapter tube holes; the integral appearance of the valve body is cross; the outer ends of the two adapter tube holes are both connected with adapter tube nozzles; the valve plug is positioned in the main body of the valve body and is coaxial with the main body of the valve body; the middle of the valve plug is provided with a columnar valve hole; and the valve plug is driven by the operation handle to rotate for 90 degrees, so that the valve hole and the adapter tube nozzle are coaxially connected, or the adapter tube nozzle is plugged and closed by the valve plug. The stop valve disclosed by the invention can be operated within the range of 90 degrees by taking the axis of the valve plug as the center, i.e., a fuel path can be switched on and cut off, and the fuel does not need to be completely discharged. Therefore, the problem of fuel waste in the prior art is solved, and the stop valve used for the aircraft fuel system has the advantages of small volume and convenience in use.
Description
Technical field
The present invention relates to the working service technical field of aircraft oil-fired system, specifically, relate to a kind of aircraft oil-fired system stop valve.
Background technique
The aircraft oil-fired system need regularly be safeguarded during use, and is present, some aircraft is because structure space restriction, can't installation pipeline switching control valve, therefore, the aircraft oil-fired system needs the fuel oil in the system is all drained when safeguarding, so that system becomes the dismounting of annex pipeline.But wasted thus a large amount of fuel oils.
The present invention is exactly to address the above problem as starting point, be solution maintenance process intermediate fuel oil waste problem, be intended to be implemented in the very little situation of installing space, can install and handle easily, so that the fuel oil in the oil-fired system need not drain when safeguarding, saved cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to the reality needs, a kind of aircraft oil-fired system stop valve is provided.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
A kind of aircraft oil-fired system stop valve, comprise valve body, spool, operating grip, described valve body main body is hollow circular cylinder, mouth is taken over two hollow cylindricals in the both sides of valve body main body, the monnolithic case of described valve body is cross, described two outer ends of taking over mouth all are connected with connecting-tube nozzle, described spool is positioned at valve body body interior and coaxial with the valve body main body, described spool middle part is provided with the column valve opening, and described spool drives by operating grip and rotates 90 ° so that the coaxial connection of valve opening and connecting-tube nozzle or spool stop up connecting-tube nozzle closed.
Described spool is cylindric spool, and institute's spool and described body wall seal by seal ring.
The above and below of described spool is respectively equipped with upper cap nut end cap and lower nut end cap, and described upper cap nut end cap and lower nut end cap are enclosed in valve inner with spool.
Beneficial effect of the present invention is:
1. stop valve can operate in the scope of 90 degree centered by the axis of spool, namely connects and close fuel path, will all not give out light by fuel oil, has solved the problem of the waste fuel oil that exists in the prior art;
2. the stop valve volume is little, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of stop valve of the present invention when being in open mode.
Fig. 2 is the structural representation of stop valve of the present invention when being in closed condition.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of aircraft oil-fired system stop valve, comprise valve body 1, spool 4, operating grip 3, described valve body 1 main body is hollow circular cylinder, mouth 10 is taken over two hollow cylindricals in the both sides of valve body 1 main body, the monnolithic case of described valve body 1 is cross, described two outer ends of taking over mouth 10 all are connected with connecting-tube nozzle 6, like this, stop valve and connecting-tube nozzle 6 are designed together, the two ends of connecting-tube nozzle 6 can be used for connecting the turnover oil pipe line, described spool 4 is positioned at valve body 1 body interior and coaxial with valve body 1 main body, described spool 4 middle parts are provided with column valve opening 7, and described spool 4 drives by operating grip 3 and rotates 90 ° so that valve opening 7 stops up connecting-tube nozzle 6 closed with connecting-tube nozzle 6 coaxial connections or spool 4.In the present embodiment, spool 4 is fastening by locating stud 9 riveted joints with handle 3.
Described spool 4 is cylindric spool, and institute's spool 4 seals by seal ring 5 with described valve body 1 sidewall, and connecting-tube nozzle 6 is realized sealing with the adapter mouthful same seal ring 5 that passes through.
The above and below of described spool 4 is respectively equipped with upper cap nut end cap 2 and lower nut end cap 8, and described upper cap nut end cap 2 and lower nut end cap 8 are enclosed in valve body 1 inside with spool 4.
Stop valve of the present invention can operate in the scope of 90 degree centered by the axis of spool, namely connects and close fuel path, will all not give out light by fuel oil, has solved the problem of the waste fuel oil that exists in the prior art; Simultaneously, the stop valve volume is little, and is easy to use.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and variation; but only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
