Abstract
The utility model discloses a length-adjustable pipe fitting connecting piece, which comprises a round tube, a connection tube and a left nut and a right nut. The round tube and the connection tube realize closely dynamic cooperation through the sealing ring on the round tube. When the distance between the tubes is immutable, the connection components can self adjust the mounting length for matching with the distance between the tubes. The utility model has advantages of convenient mounting, simple structure and perfect sealing effect.
Description
Technical field
The utility model relates to the link between a kind of pipe fitting, particularly a kind of length adjustable pipe connecting component.
Background technique
In industrial production, engineers and technicians often need to use a large amount of pipe connecting components at erection unit, when arranging pipeline, so that being connected between pipeline and pipeline, pipeline and valve and various other pipe fittings.Same in all kinds of decorations of daily life, people still unavoidably can run into the connectivity problem between many pipe fittings.
The length of installation of existing pipe connecting component is changeless, when mounted, requirement to distance between two connecting tubes is very strict, if this distance is greater than or less than the length of installation of link, all will bring difficulty to installation, especially in those construction occasions of being had relatively high expectations in pipe fitting mounting point, less range deviation even cause pipe fitting normally to connect.Like this, will bring huge inconvenience to producing, constructing.
Summary of the invention
The utility model technical issues that need to address provide a kind of length adjustable pipe connecting component.When adopting the utility model to carry out the pipe fitting connection, when distance between the pipe fitting was immutable, pipe connecting component can make it to be complementary with this distance by regulating the length of installation of self, can guarantee the sealability of pipe fitting when being convenient to install, thereby overcome the defective that exists in the prior art.
The utility model is achieved in that
The said length adjustable pipe connecting component of the utility model is an assembly parts, comprising:
One one end is provided with the pipe that step, the other end are provided with caulking groove, and step is provided with one or more grooves, places seal ring in the groove, and the external diameter of seal ring is provided with baffle ring greater than the external diameter of step in the caulking groove, and the external diameter of baffle ring is greater than the external diameter of pipe;
An adapter that socket-connects with pipe is taken in the pipe of an end and is provided with projection, and seal ring and nozzle inner wall are closely movable to be cooperated, and the other end is provided with outside thread;
One be enclosed within on the pipe, with take over the left nut that outside thread is meshed, the internal diameter of left nut is less than the external diameter of step;
A right nut that is enclosed within on the pipe, the internal diameter of right nut is less than the external diameter of baffle ring.
Described pipe fitting comprises valve, threeway, straight tube etc.
The utility model is to use like this:
The utility model is when connection pipe fitting, and an end can link to each other with a pipe fitting by the right nut on the pipe, and the other end connects or mode such as be threaded is connected with another pipe fitting by taking over flange.During connection, can assemble this link earlier, link to each other with two pipe fittings respectively again, also can earlier pipe be connected with pipe fitting respectively with adapter, again pipe and adapter be linked together.
When pipe and adapter socket-connect, on the one hand since the external diameter of seal ring with take over internal diameter equate that make seal ring to realize that closely activity cooperate with nozzle inner wall, promptly pipe can move freely, and has guaranteed the sealing between adapter and the pipe simultaneously in adapter; On the other hand, owing to be provided with projection in the pipe of adapter one end, limited further moving of pipe to the connecting tube direction.When assembling this link, according to the distance between the connecting tube, can first mobile pipe, regulate the built-in length of pipe in taking over after suitable, be connected with the outside thread of adapter with left nut again, to fix the relative position of adapter and pipe.
Because the internal diameter of right nut when making right nut sleeve on body, is limited by baffle ring less than the external diameter of baffle ring, unlikelyly come off or lose, and with being connected of pipe fitting the time, play fixing right nut.
Be equipped with packing ring in left side nut and the right nut,, guarantee the unlikely leakage of fluid with further sealing.
Seal ring and packing ring are materials such as teflon, rubber, nylon, are best with the teflon.
The utlity model has following advantage:
1, the convenient installation.Be particularly conducive to the fixed distance between the connecting tube and need to regulate the occasion that link is complementary with it.
2, simple in structure.Used component number seldom, structure is convenient to manufacturing.
3, good sealing effect.Sealing effect has been guaranteed in the setting of a plurality of seal rings and packing ring preferably.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of length adjustable pipe connecting component;
Fig. 2 is an I place partial enlarged drawing among Fig. 1.
Embodiment
By Fig. 1 and Fig. 2 as seen, the utility model comprises:
One one end is provided with the pipe 1 that step 101, the other end are provided with caulking groove 102, step 101 is provided with two grooves 103, places seal ring 104 in the groove 103, and the external diameter of seal ring 104 is greater than the external diameter of step 101, be provided with baffle ring 105 in the caulking groove 102, the external diameter of baffle ring 105 is greater than the external diameter of pipe 1;
An adapter 2 that socket-connects with pipe 1 is taken over 2 one ends and is provided with outside thread 201, is provided with the annular protrusion 202 that extends radially in the pipe of the other end, and seal ring 104 closely contacts with the inwall of taking over 2, and pipe 1 can move freely in adapter 2, and the realization activity cooperates;
One is enclosed within left nut 3 on the pipe 1, that be meshed with outside thread 201, and the internal diameter of left nut 3 is less than the external diameter of step 101;
A right nut 4 that is enclosed within on the pipe 1, the internal diameter of right nut 4 is less than the external diameter of baffle ring 105.
