Abstract
The utility model discloses a hydraulic pneumatic pipe connector which comprises an O-shaped ring, a locking nut, a blocking ring, and a straight pipe connector. The hydraulic pneumatic pipe connector is characterized by installing the locking nut in the straight pipe connector, installing the blocking ring, screwing the locking nut tightly, pressing the straight pipe connector tightly, achieving the connection and sealing. The hydraulic pneumatic pipe connector is simple in structure, convenient to use, low in cost and good in sealing performance.
Description
Technical field
The utility model relates to a kind of hydraulic pneumatic pipe joint.The pipeline that mainly applies to all kinds of non-strong corrosive fluids (being connected water etc., general gas flow pipeline such as diesel oil, gasoline, lubricant oil, petrol engine and Diesel Engine Coolants) connects and sealing.
Background technique
At present, the connection between the hydropneumatic pipeline pipe joint is commonly used the locking nut connection with being connected.When using locking nut to connect, generally locking nut must be packed into pipe joint, then tighten locking nut, thereby compress pipe joint.Because locking nut must pack into pipe joint, this external diameter that just defines pipe joint one end must be less than the excessively nail hole of locking nut.If the external diameter of pipe joint is limited, need to increase transit joint in the time of certainly will causing pipe joint to be connected with other parts.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic pneumatic pipe joint simple in structure, solves connection and the sealing problem of existing hydropneumatic pipeline, and reduces manufacture cost, good airproof performance.
Technical solution of the present utility model is such, a kind of hydraulic pneumatic pipe joint comprises O type circle, locking nut, back-up ring, free flow coupling, it is characterized in that an end of free flow coupling has stair ring, stair ring is equipped with O type circle, back-up ring, and locking nut is arranged.
Back-up ring, O type circle at the locking nut internal diameter between the free flow coupling.
The little ladder circle in free flow coupling outer end has annular groove, mounting O-shaped rings, and inner large ladder circle has annular groove, and back-up ring is installed.
The utility model has the advantages that, simple in structure, good airproof performance, with low cost.
Description of drawings
It is such that structure of the present utility model consists of:
Fig. 1 is that the integrally-built master of a kind of hydraulic pneumatic pipe joint of the utility model looks sectional view.
Fig. 2 is the integrally-built outline drawing of a kind of hydraulic pneumatic pipe joint of the utility model.
Fig. 3 is the back-up ring view of a kind of hydraulic pneumatic pipe joint of the utility model.
Among Fig. 1～Fig. 3, O type circle (1), locking nut (2), back-up ring (3), free flow coupling (4).
Embodiment
Most preferred embodiment of the present utility model is such, and with reference to accompanying drawing, free flow coupling (4) is processed with 1 counterbore with angle coupling body connecting end, in order to place back-up ring (3).See Fig. 2, use back-up ring (3), back-up ring (3) can be made U-shaped, semicircle, square etc.See Fig. 3, during use, free flow coupling (4) holds greatly little ladder circle that annular groove is arranged, and O type circle (1) is installed; Large end circle has annular groove, and back-up ring (3) is installed.Locking nut (2) is packed into free flow coupling (4), load onto back-up ring (3), screw locking nut (2), compress free flow coupling (4), realize connecting and sealing.
Claims (3)
1. hydraulic pneumatic pipe joint, comprise O type circle, locking nut, back-up ring, free flow coupling, an end that it is characterized in that free flow coupling (4) has stair ring, and stair ring is equipped with O type circle (1), back-up ring (3), and locking nut (2) is arranged.
2. according to a kind of hydraulic pneumatic pipe joint claimed in claim 1, it is characterized in that back-up ring (3), O type circle (1) at locking nut (2) internal diameter between the free flow coupling (4).
3. according to a kind of hydraulic pneumatic pipe joint claimed in claim 1, it is characterized in that the little ladder circle in free flow coupling (4) outer end has annular groove, mounting O-shaped rings (1), inner large ladder circle has annular groove, and back-up ring (3) is installed.
