Abstract
The utility model discloses a high pressure joint, which comprises a screw rod with a conical head and a nut. The center of the screw rod is provided with oil holes, the diameter of the oil hole on the conical head side is larger than that on the other side of the screw rod, and steps are formed between the two sections of the oil holes. The oil hole on the conical head side is provided with a valve core and a plug with a through hole from inside out, the valve core and the plug are connected through a spring, and the valve core is in sealed match with the oil hole on the other side of the screw rod. Parts including the valve core, the spring and the like are arranged in the oil hole of the high pressure joint, thereby enabling the high pressure joint to have a one-way valve function and being simple in structure, convenient to use and low in cost.
Description
Technical field
The utility model relates to a kind of high pressure joint.
Background technique
High pressure joint has obtained using widely in hydraulic system, main effect is to connect oil pipe and valve member, its structure is the screw rod that an end has the conical surface, be provided with a through hole in the middle of the screw rod, nut sleeve is on screw rod, the screw rod conical surface is used for sealing, the screw rod intermediate throughholes is used for passing through of fluid, nut is used to connect the valve member of other oil pipes, this structure high pressure joint mainly is to play other oil pipes and the valve member effect of connecting, require fluid unidirectionally to pass through in the system that has, this high pressure joint this moment can't be used, and use one-way valve to replace and then can improve cost of production.
The model utility content
The purpose of this utility model provides a kind of high pressure joint that has non-return valve function.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high pressure joint comprises the screw rod and the nut that have conehead, and the screw rod center is provided with oilhole, and the oilhole diameter of conehead side forms step greater than opposite side oilhole diameter between two sections oilholes; Be provided with the plug of spool and band through hole in the oilhole of conehead side from inside to outside, spool is connected by spring with plug, and spool and opposite side oilhole are sealed and matched.
Described spool is a steel ball, and steel ball size is less than the oilhole diameter of conehead side and greater than opposite side oilhole diameter.
Described plug and oilhole are by being threaded.
In the utility model, parts such as spool and spring are set in oilhole, make high pressure joint have non-return valve function, simple in structure, easy to use, cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of high pressure joint comprises the screw rod 7 and the nut 6 that have conehead, and screw rod 7 centers are provided with oilhole, and oilhole 5 diameters of conehead side form step greater than opposite side oilhole 1 diameter between two sections oilholes; Be provided with the plug 4 of steel ball 2 and band through hole in the oilhole 5 of conehead side from inside to outside, steel ball 2 is connected by spring 3 with plug 4, and steel ball 2 is sealed and matched with opposite side oilhole 1.Steel ball 2 diameters are less than the diameter of the oilhole 5 of conehead side and greater than the diameter of opposite side oilhole 1.The oilhole 5 of described plug 4 and conehead side is by being threaded.
Working principle of the present utility model is: fluid enters from oilhole 1, pushes steel ball 2 under the effect of pressure open, and fluid flows out from the oilhole 5 of conehead side, and can not reflux, and plays the effect of one-way valve.
