Abstract
The utility model belongs to a fitting of pipeline connection, particularly an opening ring with an inner thread used for a pipe joint without a thread. The opening ring is a circular ring with an opening, the outer contact surface of the circular ring is in a spherical surface shape and the inner contact surface is provided with a metric thread. The opening ring is matched with a locking nut with the inner thread and the pipe joint with an outer thread. The opening ring is designed into the spherical surface shape with a guiding function and the opening ring is extruded by rotating the locking nut to enable the opening of the opening ring to be gradually reduced. Under the condition of same length, clamping dimension has the advantages of large adjusting quantity, firmer pipeline connection, etc. The inner contact surface of the opening ring is a metric thread and thus the locking force of the outer surface of a connected pipe can be reinforced to prevent a connecting pipe from loosening.
Description
Technical field
The utility model belongs to the pipeline connection fittings, particularly the screw-thread-free pipe joint trip ring that has internal thread.
Background technique
Pipeline is installed and adopted screw-thread-free pipe is the new technology that modern pipeline is in the world installed, and also promotes day by day in China.And have threaded passage to install to compare, it have install rapidly, good airproof performance, scene do not need the special screw thread process equipment and advantage such as reusable, needn't tapping, need not weld and the situation of reaming under just two tubes can be coupled together.Screw-thread-free pipe joint is one of vitals that connects screw-thread-free pipe, and trip ring is a critical component of forming screw-thread-free pipe joint, and its structural design and quality quality directly influence the installation effect of pipeline.And at present used trip ring is one to have the annulus of opening, when mounted, and the pipeline of chucking various outer diameter under the effect of locking nut, and two tubes coupled together.Because the one side that contact with connected tube of trip ring is an even surface, thus increase suddenly in the pipeline internal pressure, pipeline vibrations and other external force under acting on, connecting pipeline becomes flexible easily, causes gas or leak of liquid in the connecting pipeline.
Summary of the invention
The purpose of this utility model is the defective that overcomes existing trip ring technology, a kind of screw-thread-free pipe joint trip ring that has internal thread is provided, with avoid increasing suddenly in the pipeline internal pressure, pipeline vibrations and other external force under effect, gas in the pipeline or leak of liquid.
Trip ring described in the utility model is one to have the annulus of opening, and the outer contacting face of annulus is a spherical shape, and interior surface of contact has metric thread.
Described trip ring available metal is made, as stainless steel.
The opening of trip ring of the present utility model (otch) forms by block ring body perpendicular to lower plane, and it is the pipeline in order to make trip ring make trip ring the surplus of deflation be arranged and tighten various outer diameter under the effect of locking nut; Interior surface of contact is a metric thread, in order to strengthen the coupling mechanism force with tube outer surface, effectively prevent because of the pipeline internal pressure increases suddenly, pipeline vibrations and other external force under effect, connecting pipeline is loosening, avoids gas or leak of liquid in the pipeline; Because trip ring outer contacting face is designed to spherical shape, increased the surface of contact of trip ring and locking nut internal surface, so when locking nut is tightened on pipe joint gradually, increase along with the extruding force of locking nut, be easy to force the opening of the trip ring that is installed in locking nut the inside (sphere towards opposite) to dwindle gradually with the moving direction of locking nut, so just give full play to the leading role of sphere, and in limited length range, obtained maximum adjustment amount.
The utility model can be applicable to pressure less than 1.6Mpa (16 kilograms per centimeter
2) air, oil, water piping system industries such as applicable oil, chemical industry, automobile, rolling stock, lathe manufacturing are installed.
The utility model is compared with existing trip ring, has wear resistance and good airproof performance, and because trip ring is designed to have the spherical shape of leading role, so the chucking size has advantages such as adjustment amount is big, the pipeline connection is more firm under equal length.

Embodiment
Embodiment:
See also Fig. 1 and 2.Adopt stainless steel annulus material, with the internal surface tapping metric thread 1 of annulus, the outer surface of annulus is processed into sphere 2 shapes, blocks ring body perpendicular to lower plane and forms an opening 3.
The locking nut that will have internal thread is enclosed within outside the connected tube, the utility model trip ring that shapes is enclosed within outside the pipe and in locking nut, pad and O type rubber seal further are installed then, locking nut with have externally threaded pipe joint and cooperate, because trip ring is the annulus of a sphere, by rotational lock nut extruding trip ring, the opening of trip ring is dwindled gradually, will manage securely and couple together; Again since in the trip ring surface of contact be metric thread, can strengthen the coupling mechanism force with the outer surface of connected tube, prevent that connecting tube is loosening.
