Abstract
The invention discloses a design of a universal hydraulic pipe joint. The designed joint comprises two welding type hinged pipe joints with the standard number of JB/T978-1977 and the transition joint of the direct type pipe of an inner thread; wherein the transition joint is welded with the radial opening of the welding type hinged pipe joint I; the welding type hinged pipe joint II is connected with the transition joint; both the two welding type hinged pipe joints can freely revolve by 360 degrees along the self body; the revolving motion of the welding type hinged pipe joint II is still vertical to the revolving motion of the welding type hinged pipe joint I; and the hydraulic fluid port of the joint II can be led to obtain a feel space direction by adjusting the revolving angles of the two joints. The universal hydraulic pipe joint designed by the invention leads a metal pipe or a hydraulic hose to be easily jointed, can optimize the direction of the metal pipe, leads the hydraulic hose to be reasonably bent, and avoids the problem of causing the distortion of the hose. As a standard element and the transition joint with simple structure are employed, the universal hydraulic pipe joint is simple to be manufactured and has low cost.
Description
Technical field
The present invention relates to hydraulic plumbing system, particularly a kind of design of universal hydraulic coupling.
Background technique
In hydraulic plumbing system, often use various pipe joints, that wherein can adjust direction has swivel joint and a welding type hinged pipe joint, these two kinds of joints all can only be adjusted direction in two dimensional surface, can't in three dimensional space, adjust direction arbitrarily, therefore under some special spatial condition, when connecting with metal tube or hydralic hose with these pipe joints, can cause the butt joint difficulty, particularly for hydralic hose, sometimes also cause sebific duct distortion easily or make bending radius too small, thereby influence sebific duct working life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of design of universal hydraulic coupling, joint is docked with metal tube or hydralic hose become easily, can realize conveniently that sebific duct is rationally crooked, avoids causing problems such as sebific duct distortion or bending radius be too small.
To achieve these goals, the present invention adopts following technological scheme:
The design of universal hydraulic coupling of the present invention comprises following content:
1, universal hydraulic coupling is made up of two welding type hinged pipe joints and a transit joint;
2, described welding type hinged pipe joint employing standard No. is the standard component of JB/T978-1977 or other element that employing has equivalent structure and technical characteristics;
3, transit joint is a tapped free flow coupling;
4, the radially hydraulic fluid port of transit joint and welding type hinged pipe joint one welding, welding type hinged pipe joint two connects with transit joint; Two welding type hinged pipe joints can freely turn round around self 360 degree, the rotation motion of welding type hinged pipe joint two is all the time perpendicular to the rotation motion of welding type hinged pipe joint one, adjust the angle of revolution of two joints, can make the hydraulic fluid port of joint two obtain direction in space arbitrarily.
The beneficial effect that the present invention produces is: because universal hydraulic coupling can be adjusted hydraulic fluid port towards direction in space arbitrarily, therefore just dock with metal tube or hydralic hose and be very easy to, can reach and optimize the metal tube trend and make the rationally crooked purpose of hydralic hose, avoid causing problems such as sebific duct distortion or bending radius be too small; And the utility model adopted the standard component of easy purchase and transit joint simple in structure, has the simple advantage with low cost of making.
Description of drawings
Fig. 1 is total figure of the embodiment of the invention.
Fig. 2 is the structural drawing of transit joint.
Embodiment
As shown in Figure 1, the embodiment of the invention is made up of welding type hinged pipe joint 1, transit joint 2, welding type hinged pipe joint 23.Welding type hinged pipe joint 1 has axial hydraulic fluid port 11 and radially hydraulic fluid port 12, radially hydraulic fluid port 12 and transit joint 2 welding.The structure of transit joint 2 has a straight-through tapped hole as shown in Figure 2, and two ends are the plane, and an end is processed with chamfering, with convenient welding.Welding type hinged pipe joint 23 has axial hydraulic fluid port 31 and hydraulic fluid port 32 radially, and axially hydraulic fluid port 31 connects with transit joint 2 and connects.Because two welding type hinged pipe joints can freely turn round around self 360 degree, and the rotation motion of welding type hinged pipe joint two is all the time perpendicular to the rotation motion of welding type hinged pipe joint one, two vertical rotation motions can make hydraulic fluid port 11 and hydraulic fluid port 32 that space angle is arbitrarily arranged, that is to say that hydraulic fluid port 32 can obtain direction in space arbitrarily when hydraulic fluid port 11 fixedly the time.
When the connection direction of concrete adjustment pipe joint, can earlier two radial type pipe couplings be unclamped, adjust the solid of rotation of two pipe joints respectively, treat again two pipe joints to be tightened after the satisfaction of hydraulic fluid port direction.
