Abstract
The utility model belongs to needle-valve technical field more particularly to a kind of valve rod for hydraulic cushion needle-valve.The technical problem to be solved by the utility model is to provide one kind can reduce oil pressure, is easily installed, the valve rod that physical life is long, sealing effect can be used for well hydraulic cushion needle-valve.To solve the above-mentioned problems, technical solution provided by the utility model is: a kind of valve rod for hydraulic cushion needle-valve, the leading portion of the valve rod is provided with locking screw, and the needle-valve further includes locator and sealing ring, and the sealing ring and the locator are to be tightly connected.The utility model has the beneficial effects that: the utility model is preposition by screw thread, part sealing ring and locator postposition solve the problems, such as that oil leakage occurs after being used for a long time, and can reduce oil pressure by preposition screw thread；In addition to this, technical solution installation and adjusting provided by the utility model are all more convenient.
Description
Technical field
The utility model belongs to needle-valve technical field more particularly to a kind of valve rod for hydraulic cushion needle-valve.
Background technique
Valve rod is the critical component in needle-valve.The stem structure of existing needle-valve is related to existing that installation is inconvenient, the service life is short, especially
It, which is that long-time is practical, will appear the failures such as oil body leakage.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can reduce oil pressure, is easily installed, physical life
Long, sealing effect can be used for well the valve rod of hydraulic cushion needle-valve.
To solve the above-mentioned problems, technical solution provided by the utility model is:
A kind of valve rod for hydraulic cushion needle-valve, the leading portion of the valve rod are provided with locking screw, and the needle-valve also wraps
Locator and sealing ring are included, the sealing ring and the locator are to be tightly connected.
Optionally, the back segment of the valve rod is provided with seal groove, and the sealing ring is placed in the seal groove.
The utility model has the beneficial effects that: the locator and sealing ring of traditional valve rod be not preposition, screw thread is postposition,
This setup, it is practical long after, be easy to happen oily leakage.The utility model is preposition by screw thread, part sealing ring and
Locator postposition solves the problems, such as that oil leakage occurs after being used for a long time, and can reduce oil pressure by preposition screw thread；Except this
Except, technical solution installation and adjusting provided by the utility model are all more convenient.
