[0010] Further improvement lies in that the outer part of the main valve sleeve is equipped with the external thread matched with the valve block.
[0011] Further improvement lies in that the sliding valve core is pressed into the main valve sleeve with interference.
[0012] Further improvement lies in that the both sides of the main valve sleeve are equipped with the O type ring groove, and the O type ring is installed on the O type ring groove.
[0013] Further improvement lies in that the both sides of the inner hole of the main valve sleeve are machined with the inner hexagon.
[0014] Further improvement lies in that the spring is the tower type spring.
[0015] 3. Beneficial effects:
[0016] Compared with the prior art, the technical scheme has the beneficial effects that:
[0017] The sealing mode of the one-way valve provided by the utility model adopts plane sealing, effectively reduces the internal leakage of the product, and can freely adjust the oil passage and reverse cut-off direction, improving convenience. BRIEF DESCRIPTION OF DRAWINGS

[0023] In order to facilitate understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings, and the drawings show several embodiments of the utility model, however, the utility model can be realized in many different forms, and is not limited to the embodiments described herein, on the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
[0024] In the utility model, unless another explicit provision and limitation, the terms "installation", "connection", "connection", "fixing", "provided with" and other terms should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through the intermediate medium, can be the communication of two elements inside. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0025] It should be noted that the structure not introduced in the utility model is not related to the design points and improvement direction of the utility model, and adopts the prior art.
[0026] Reference Figs. 1-3The embodiment of the application discloses a new type of zero-leakage embedded one-way valve, which comprises a main valve sleeve 1, a sliding valve core 2, a gasket 3, a spring 4, a snap spring 5 and an O-shaped ring 6, and is installed in an inner pipeline mode.
[0027] The spring 4 is a tower type spring, one end of which is connected to the snap spring, and the other end of which is connected to the gasket, so that the tower type spring can correctly play its role.
[0028] The connection mode of the sliding valve core 2 and the gasket 3 is not limited, and the two can be fixedly connected, detachably connected or abutted.
[0029] The main valve sleeve 1 is internally provided with the sliding valve core 2, the gasket 3, the spring 4 and the snap spring 5.
