Description
Technical field
This utility model relates to the auxiliary products field of X-type aircraft fuel system, specifically a kind of X-type aircraft fuel system oil drain cock.
Background technology
Rubber parts Sealing Technology is widely used, reaches its maturity, the various equipment with auto-lock function are also widely used for the every field such as military affairs, industry, but X-type aircraft fuel system oil drain cock is due to sealing, safety, reliability and simple to operate, the most convenient etc. strict demand, and its supporting research and development have yet to begin starting.The feature of X-type aircraft fuel system oil drain cock maximum is in addition to use the rubber parts such as the oil resistant of technology maturation, high temperature resistant, solvent resistant to realize beyond positive sealing and seeks to realize the self locking safety function of oil drain cock and function simple to operate, this is accomplished by increasing many safety measures to realize security function, but the most also to avoid complicated loaded down with trivial details operation.X-type aircraft fuel system oil drain cock is exactly one of which, and the purpose of this oil drain cock is through simply, stirs handle flexibly, realizes the fuel oil in quick drain fuel tank, and can guarantee that positive sealing and safe self-locking, prevents fuel blow.In sum, X-type aircraft fuel system oil drain cock is requisite visual plant on X-type aircraft fuel system, is to realize X-type aircraft fuel system quickly to drain the oil, reliably seal and the key equipment of self-locking.
Utility model content
The purpose of this utility model is to provide a kind of X-type aircraft fuel system oil drain cock, realizes the opening and closing of oil drain cock by simple and convenient handle of stirring, thus realizes quickly opening of plug-in fuel tank and drain the oil and reliably close sealing.
The technical solution of the utility model is as follows:
A kind of X-type aircraft fuel system oil drain cock, include and be fixedly mounted on the valve seat of fuel outlet bottom fuel tank, it is characterized in that: the bottom of described valve seat is provided with oil-out and is provided with blanking cover, the top of valve seat is installed with the valve bonnet extended within fuel tank, is communicated with oil-out and the oil-through hole within described valve bonnet bottom it in valve seat；Surrounding around described valve bonnet outer wall is respectively equipped with its internal and within fuel tank multiple through holes of connection, the top of described valve bonnet has fixing seat, through hole it is provided with and by being slidably installed the valve rod downwardly extended in described fixing seat, the bottom of described valve rod is fixedly connected with spool, the surrounding of described spool is close to the inwall of described valve bonnet and can slide up and down along the inwall of described valve bonnet, is set with spring between the external described fixing seat of described valve rod and described spool；The upper surface of described valve seat is the sealing surface matched with described spool, it is rotatablely equipped with rotating shaft in described oil-through hole, one end of described rotating shaft is extended in described valve seat and is fixedly connected with handle, cam is installed in rotating shaft, the protuberance of described cam acts against on the inwall of described oil-through hole and relative with the position of described handle, and the lower end of cam acts against the inner side of described blanking cover.
Described X-type aircraft fuel system oil drain cock, it is characterised in that: it is connected between described valve seat with described blanking cover and has chain.
Described X-type aircraft fuel system oil drain cock, it is characterised in that: the top of described valve seat is provided with seal washer between the faying face of fuel outlet bottom fuel tank.
Described X-type aircraft fuel system oil drain cock, it is characterised in that: the lower surface of described spool connects the sealing ring matched with described valve seat upper surface.
This utility model is arranged on the bottom of fuel tank, the excess oil in quick drain fuel tank, can conveniently discharge excess oil and can realize again reliably sealing.When not draining the oil, oil drain cock is closed, and handle is generally horizontal, now, lower cam end can be propped up by blanking cover, makes cam self-locking not rotate, spool is pressed on sealing surface under the action of the spring, it is achieved thereby that the closedown sealing of oil drain cock and self-locking.
When draining the oil, first turning on blanking cover, release the blanking cover self-locking to cam, pull about 90 ° of handle clockwise, drive cam rotation by rotating shaft, cam can be by spool upwards jack-up, and spool separates with sealing surface, and now oil drain cock is opened, and the fuel oil in fuel tank is released.Handle being pulled about 90 ° counterclockwise, drives cam rotation by rotating shaft, the most under the action of the spring, spool can follow the rotation of cam closely and move down, until spool is pressed on sealing surface realization and seals by spring force；Being tightened by blanking cover, blanking cover can prop up the lower end of cam again, makes cam self-locking not rotate, thus again achieves closedown sealing and the self-locking of oil drain cock.The most both can realize quickly opening of fuel tank drain the oil and reliably close sealing.
In view of the importance of sealing member, seal washer have employed the elastomeric material with performances such as good oil resistant, high temperature resistant, solvent resistant, and sealing property is reliable.
In terms of safety, this oil drain cock has a multiple tracks safety measures: (1), when oil drain cock cuts out, and tightens blanking cover, and blanking cover can prop up the lower end of cam makes it not rotate, and the most there is not accident collision handle and causes the phenomenon drained the oil；(2), when draining the oil, backing out blanking cover, have chain to be connected between blanking cover with valve seat, the blanking cover backed out does not falls out and is put by arbitrarily losing；(3), stir handle and push against to the protuberance of cam and the inwall of oil-through hole, will not reverse voluntarily after release handle, it can be ensured that fast and reliable is drained the oil.This oil drain cock by every environmental test and the checking of qualification test, can be applicable on fuel tank and the other type of fuel tank of each machine fuel system.
The beneficial effects of the utility model:
This utility model is rational in infrastructure, reliable in quality, simple to operate, each machine fuel system fuel tank can be met and other types fuel tank is quickly drained the oil, reliably sealed and the use requirement of safe self-locking.
