Abstract
The utility model discloses a one-way fluid pipeline joint which comprises a joint body, and is characterized in that a hollow cavity at the middle section of the drift diameter of a pipeline of the joint body is internally provided with a set of one-way valve component, so that a joint of a one-way valve can be formed; and the pipe diameter of the hollow cavity at the middle section of the drift diameter of the pipeline of the joint body is larger than that of the drift diameter of pipelines at two ends. The volume and the weight of the joint are approximate to those of the existing single joint or the one-way valve, so that the space in a one-way fluid pipeline is saved, and the weight is reduced; furthermore, the installation is very convenient, the sealing property and the durability of the pipeline are good, and the one-way fluid pipeline joint is particularly suitable for the environment with narrow space and multiple one-way fluid pipelines.
Description
Technical field
The utility model relates to a kind of joint of hydraulic pipe line, and what be specifically related to is joint in a kind of unidirectional hydraulic pipe line.
Background technique
Pipe joint is continuity pipeline length and/or parts that connect branch line.Existing pipe joint is that an axial location has pipeline latus rectum, the threaded fittings body of two ends outer side wall (as shown in Figure 1), and its simple structure plays UNICOM's effect.If will in one section pipeline, connect the branch line of an one-way fluid, except a this joint is installed, also the connection that an one-way valve just can be finished the one-way fluid pipeline must be equipped with, and Sealing and locking device must be installed additional between one-way valve and the joint.The application of this pipe fitting and Placement are very general in general environment and occasion, but in the many environment of the narrow and small and one-way fluid pipeline of some installing spaces, for example on astrovehicle, just highlight and reveal joint and defective such as one-way valve takes up space greatly, overall weight is big, not only many in the installation process owing to parts, time-consuming, and the sealing of pipeline and durability are relatively poor.
The model utility content
The purpose of this utility model is to overcome existing joint and acts on single defective in the one-way fluid pipeline, proposes a kind of one-way fluid pipe joint that integrates joint and one-way valve.
The technological scheme that realizes above-mentioned purpose is: a kind of one-way fluid pipe joint, comprise fittings body, it is characterized in that in the cavity of the pipeline latus rectum stage casing of described fittings body, being equipped with a cover check valve assembly, form the joint of a band one-way cock, the cavity in described fittings body pipeline latus rectum stage casing, its caliber is greater than the caliber of two ends pipeline latus rectum.
The volume and weight of this joint is close with existing single joint or an one-way cock, in the one-way fluid pipeline, saved the space, alleviated weight, and install easily, the sealing and the durability of pipeline are fine, are particularly suitable for using in the many environment of the narrow and small and one-way fluid pipeline in space.
Description of drawings
Fig. 1 is existing pipe joint schematic representation.
Fig. 2 is an organigram of the present utility model.
Fig. 3 is the utility model assembling schematic representation.
Among the figure: 1. fittings body, 2. pipeline latus rectum, 3. cavity, 4. spool, 5. spring, 6. spring seat.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model one-way fluid pipe joint is made of a fittings body and a cover check valve assembly, and check valve assembly is installed in the stage casing cavity of fittings body, forms the joint of a band one-way cock.The caliber in fittings body 1 axial location pipeline latus rectum 2 stage casings is greater than the caliber at two ends, the left and right sides, form the cavity 3 of big caliber, in this cavity 3, check valve assembly spool 4, spring 5 and spring seat 6 are installed wherein successively, the front-end face of spool 4 forms line/face with an end bead of described cavity 3 and contacts, and form elasticity and open/close, implement reverse sealing, as shown in Figure 2.
In the assembly process of this joint, an end of fittings body 1, i.e. the spring seat 6 residing ends installation opening that is check valve assemblies, as shown in Figure 3.After spool 4, spring 5 and spring seat 6 are installed wherein successively, adopt rolling technology installation opening to be pressed together on the ear end face of spring seat 6, promptly form the joint of the utility model band one-way cock.
Claims (1)
1. one-way fluid pipe joint, comprise fittings body, it is characterized in that: a cover check valve assembly is installed in the pipeline latus rectum stage casing cavity of described fittings body, form the joint of a band one-way cock, the cavity in described fittings body pipeline latus rectum stage casing, its caliber is greater than the caliber of two ends pipeline latus rectum.
