Description
Technical Field
The utility model belongs to the technical field of hydraulic transmission, and particularly relates to a sealing structure applied to a cartridge valve.
Background
The cartridge valve mainly has the function of controlling the on-off and switching of an oil way, and part of the cartridge valve also has the functions of pressure maintaining and safety valve; in the existing cartridge valve, the push rod and the plug are sealed by only one sealing ring, wherein two types of the sealing rings possibly cause leakage of the cartridge valve; firstly, the sealing ring is aged, damaged and the like to cause the sealing ring to fail; secondly, the cartridge valve is in a high-pressure working state; once the sealing ring fails, the cartridge valve cannot normally operate, so that a sealing structure is required to be added, and the service yield and the service life of the product are improved.
Disclosure of utility model
To solve the problems set forth in the background art. The utility model provides a sealing structure applied to a cartridge valve.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a be applied to sealing structure of cartridge valve, includes the cartridge valve body, the cartridge valve body includes push rod and end cap, the end cap offer with the agreeing with groove of push rod looks adaptation, install the sealing washer in the inner wall of agreeing with the groove, the sealing washer with the push rod is laminated mutually, the push rod is kept away from the one end of sealing washer is provided with sealing, sealing with the sealing method of end cap is face seal.
Further, the sealing mode of the sealing part and the plug is conical surface sealing.
Further, the seal ring is disposed adjacent to the seal portion.
The beneficial effects of the utility model are as follows: the double sealing structure is formed by the sealing ring and the sealing conical surface, the sealing strength between the push rod and the plug can be effectively enhanced on the premise of not increasing other structures, the cartridge valve can be sealed by the sealing ring when being in low pressure, and the cartridge valve can be sealed by the sealing conical surface when being in high pressure.
