Abstract
The utility model relates to a fuel oil switch for a diesel engine, which is composed of a valve body, valve rod, and a cap. The utility model is characterized in that a sealing position of the valve body and the cap is of conical surface; the sealing surface of the switching position of the valve body and the valve rod is of conical surface. The utility model has the advantages of good sealing effect, smart switching, strong reliability, and low cost.
Description
The utility model relates to a kind of switch, particularly a kind of diesel engine fuel oil switch.
At present, the sealing means of the fuel tap that various small diesel engines are used generally adopts rubber washer, and is easy to wear, and sealing effect is not good enough.
The purpose of this utility model is to design a kind of diesel engine fuel oil switch of good sealing effect.
The technical solution of the utility model is: it is made up of valve body, valve rod and cap, it is characterized in that valve body with and the sealing surface at the folding position of the sealing position of cap and valve body and valve rod be the conical surface.
Because also cap is between valve body and the valve rod, after screw thread tightened, the axial thrust load at sealing position made conical surface seal, and radial component makes and cap endoporus and valve stem seal, thus good sealing effect; Valve rod and valve body are advanced and retreat by screw thread, make the tip of valve rod contact or leave with the conical surface of valve body, guarantee folding freely.
Accompanying drawing is the utility model structure sectional view.
Below in conjunction with description of drawings most preferred embodiment of the present utility model.
As shown in the figure, valve body 1 bores a through hole 6, is the matching hole and the oil discharge passage of valve rod 3, the vertical oil inlet hole 7 that is provided with through hole.Valve rod cooperates with valve body and can advance and retreat in through hole by screw thread, makes the most advanced and sophisticated conical surface of valve rod contact or leave with the conical surface at folding position 5, closes oil circuit during contact, opens oil circuit when leaving.And cap 2 is arranged between threaded stem and the handle, can slidably reciprocate on valve rod, and cap is connected with valve body by screw thread, and of contacting with sealing position 4 of cap is the conical surface.Screw and cap, the axial thrust load on the conical surface makes and the cap conical surface and valve body conical surface seal, and radial component makes and cap endoporus and valve stem seal.
The tapering difference of two conical surfaces in the utility model sealing position is 2～5 °, and its area of contact is reduced, and contact pressure increases, thereby sealability is better.
Valve body of the present utility model is with also cap is by the high strength plastics manufacturing, and valve rod is by the Cuprum alloy manufacturing.
