In order to solve the technical problem, the utility model discloses a technical scheme as follows: a detachable safety valve comprises a valve body, a spring, a valve core and a plug; the valve body is provided with a stepped hole, the section with the small inner diameter of the stepped hole is an oil inlet, the section with the large inner diameter is a valve hole, a valve core and a spring are sequentially arranged in the valve hole from inside to outside, and the valve hole is blocked by a plug; the peripheral surface of the valve body corresponding to the oil inlet hole is provided with threads; the peripheral surface of the valve body corresponding to the valve hole is provided with an oil drainage hole communicated with the valve hole.
Furthermore, the plug is provided with a loose-proof gasket.
Preferably, the valve body is a hollow hexagonal prism.
Preferably, the number of drainage holes is six.
Preferably, the valve core of the valve hole is a steel ball.
Preferably, the spool of the valve bore is a plunger.
The utility model discloses the beneficial effect who gains lies in: the utility model is an independent component, has simple structure, can independently test the performance of the valve firstly and then is assembled on the oil pump, thereby greatly improving the production efficiency; the valve body adopts a structure which is convenient for screwing and connecting the valve with the pump body or the pump cover, and is provided with a plurality of oil drainage holes, so that the oil drainage capability is improved; the loosening prevention gasket is arranged between the plug and the valve body, so that the risk that the valve plug is loosened due to vibration of the oil pump in the operation process is avoided.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise. In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, mechanically or electrically connected, or interconnected between two elements, directly or indirectly through intervening media, and the specific meaning of the terms may be understood by those skilled in the art according to their specific situation.
As shown in fig. 1 and 2, a detachable safety valve comprises a valve body 1, a spring 2, a valve core 3 and a plug 4; the valve body 1 is provided with a stepped hole, the section with the small inner diameter of the stepped hole is an oil inlet, the section with the large inner diameter of the stepped hole is a valve hole, a valve core 3 and a spring 2 are sequentially arranged in the valve hole from inside to outside, and an assembly plug 4 plugs the valve hole; the peripheral surface of the valve body 1 corresponding to the oil inlet hole is provided with threads 5; and an oil drainage hole 7 communicated with the valve hole is also formed in the peripheral surface of the valve body 1 corresponding to the valve hole.
