Abstract
The utility model relates to the technical field of application and maintenance of an aircraft fuel oil system, in particular to a stop valve used for an aircraft fuel oil system. The stop valve used for the aircraft fuel oil system comprises a valve body, a valve core and an operating handle, wherein the main body of the valve body is a hollow cylinder, two hollow cylindrical pipe connection ports are arranged on the two sides of the main body of the valve body, the integral external form of the valve body is cruciform, the outer ends of the two pipe connection ports are connected with pipe connection nozzle, the valve core is positioned inside the main body of the valve body and shares the same shaft with the main body of the valve body, a columnar valve opening is formed in the middle of the valve core, the valve core drives for 90 degrees through the operating handle so as to enable the valve opening to be in connection with the pipe connection nozzle coaxially or the valve core blocks and closes the pipe connection nozzle. The stop valve provided by the utility model can be operated within a range of 90 degrees by taking the axial line of the valve core as a center, namely switching on or closing a fuel oil line, fuel oil is not required to be discharged completely, and the problem of fuel oil waste in the prior art can be solved; and the stop valve is small in volume and convenient to use.
Description
Technical field
The utility model relates to the working service technical field of aircraft oil-fired system, specifically, relates 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 limits, can't installation pipeline switching control valve, therefore, the aircraft oil-fired system needs the fuel oil in 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 utility model is exactly to address the above problem as starting point, be solution maintenance process intermediate fuel oil waste problem, be intended to realize in the situation that installing space is very little, can install and handle easily, make that the fuel oil in oil-fired system need not drain when safeguarding, saved cost.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to the reality needs, and a kind of aircraft oil-fired system stop valve is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model 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 90 ° of rotations by operating grip and makes valve opening and the coaxial connection of connecting-tube nozzle or spool that connecting-tube nozzle is stopped up closure.
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.
The beneficial effects of the utility model are:
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 utility model when being in open mode.
Fig. 2 is the structural representation of stop valve of the present utility model when being in closed condition.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
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, described spool 4 drives 90 ° of rotations by operating grip 3 and makes valve opening 7 and the coaxial connection of connecting-tube nozzle 6 or spool 4 stop up connecting-tube nozzle 6 closed.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 utility model 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 embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
