Abstract
The utility model provides a pipe joint specially used for a heat insulation pipe, which comprises at least one joint that is a first joint; and the first joint comprises a first inner sleeve, a first outer sleeve and a first separating groove arranged between the first inner sleeve and the first outer sleeve, and the first inner sleeve, the first outer sleeve and the first separating groove are arranged in a concentric way. The pipe joint specially used for the heat insulation pipe has the benefit that the inner and the outer sleeves are matched and connected with an inner and an outer pipes of the heat insulation pipe, so that the connecting and sealing performance can be improved by double-layer connection. According to the application demand, the pipe joint can be made into a pipe cap, and a two-way, three-way or four-way structure.
Description
[technical field]
The utility model relates to the pipe joint field, particularly a kind of pipe joint that is exclusively used in temperature insulation tube.
[background technique]
Pipe joint is a hydraulic pressure term, is connecting pipeline or pipeline is contained in part on the hydraulic element in the hydraulic system, and this is a kind of general name of the link that can install and remove in fluid passage.Pipe joint comprises end straight coupling, straight coupling, tee union, elbow, band nut connector alive, articulated joint, plug, transit joint etc., and its material often is stainless steel or copper.
It comprises a sleeve pipe at least existing pipe joint, and this sleeve pipe docks with connected pipe, realizes the effect that connects.But existing pipe joint can't be used in the thermal insulation pipeline, its connection and poor sealing performance.
[model utility content]
In order to solve existing technical problem, the utility model provides a kind of pipe joint that is exclusively used in temperature insulation tube, and it adopts the inner and outer pipe of inside and outside sleeve pipe and temperature insulation tube to be connected, and double-deck the connection to improve connects and sealability.
The utility model solves existing technical problem, and a kind of pipe joint that is exclusively used in temperature insulation tube is provided, and described pipe joint comprises at least one joint, and a described joint is first joint; Described first joint comprise concentric setting first inner sleeve, first outer sleeve and between first separating groove.
The utility model further improves:
The axial dimension of described first outer sleeve is less than or equal to the axial dimension of described first inner sleeve.
Described pipe joint comprises at least two joints, links to each other and forms the passage that connects through joint between the described joint.
Described joint comprises tube wall and is arranged at the thermal insulating cavity of this tube wall inside.
Described thermal insulating cavity is positioned at the passage periphery of described pipe joint.
Described pipe joint comprises heat insulation element, and described heat insulation element is dissolved in the described thermal insulating cavity.
One described joint is an inipple.
Described pipe joint is any one of 45 ° of two logical, 90 ° of two logical, 180 ° of two logical, positive threeway or four-way.
Described pipe joint comprises the joint of at least two reducings.
Compared to prior art, the beneficial effects of the utility model are: adopt the inner and outer pipe of inside and outside sleeve pipe and temperature insulation tube to be connected, the double-deck connection to improve connects and sealability.And according to application need, this pipe joint can be made pipe cap, two logical, threeway or four-way structure.

[embodiment]
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Shown in Fig. 1 to 16, a kind of pipe joint that is exclusively used in temperature insulation tube, this pipe joint comprises at least one joint, this joint is first joint 11; First joint 11 comprise concentric setting first inner sleeve 111, first outer sleeve 113 and between first separating groove 112.This first joint 11 is applicable to and connects the temperature insulation tube with inner and outer pipe.
The utility model can satisfy joint and connect the i.e. firmly stable again requirement in back, and the axial dimension of this first outer sleeve preferably is less than or equal to the axial dimension of first inner sleeve, also can be greater than the axial dimension of first inner sleeve.
Pipe joint comprises at least two joints, links to each other and forms the passage that connects through joint 12 between the joint.When pipe joint had two joints, this pipe joint was two logical; It during three joints threeway; It during four joints four-way.Joint plays connection, with each joint tandem together.
Joint of the present utility model comprises inipple 13, promptly except first joint 11, comprises an inipple 13 at least, the inwall of this inipple or outer wall are provided with worm structure 131, promptly can be internal thread, also can be outside thread, decides according to the specific requirement of using.Pipe joint with inipple is more than two logical the reaching at least.
The concrete structure of the utility model pipe joint comprises any one of 45 ° of two logical, 90 ° of two logical, 180 ° of two logical, positive threeway or four-way.And pipe joint comprises the joint of at least two reducings.Promptly the channel diameter of two joints is inconsistent.
The utility model adopts the inner and outer pipe of inside and outside sleeve pipe and temperature insulation tube to be connected, and double-deck the connection to improve connects and sealability.And according to application need, this pipe joint can be made pipe cap, two logical, threeway or four-way structure.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
