Abstract
The utility model discloses a unidirectional ventilation loose joint which includes a front joint (1), a back joint (2), and a loose joint nut (3); the loose joint nut (3) and the back joint (2) are sleeved together; a convex round ring (4) is arranged on the back joint; and the loose joint nut (3) is connected with the front joint (1) through threads. The unidirectional ventilation loose joint is characterized in that a one-way valve is arranged in the loose joint; the one-way valve includes a valve core (5) and a spring (6); the valve core (5) withstands the pipe opening (9) of the front joint; one end of the spring (6) is fixed on the valve core (5); a spring connecting frame (7) is also arranged on the front joint (1); and the other end of the spring (6) is fixed on the spring connecting frame (7). The unidirectional ventilation loose joint adopting the structure which is provided with the one-way valve in the loose joint, does not need to be additionally provided with the one-way valve on a pipeline, which is convenient to be mounted and used, and also saves the working procedures of using and maintenance.
Description
Technical field
The utility model relates to the pipe joint field, is a kind of loose joint of one-way flow specifically.
Background technique
The loose joint of prior art generally comprises front connector, back joint, loose joint nut, described loose joint nut and back adaptor cup jointing together, back joint is provided with the dome ring, the loose joint nut is connected with front connector by screw thread.Because loose joint is used for connecting tube, and pipeline when using in, a lot of occasions all need be installed one-way valve separately on pipeline, to prevent ducted liquid return.
Therefore in the middle of the prior art, one-way valve separates with loose joint, need distinguish installing and locating when installing and use, and operation bothers relatively, and this moment, rate of fault was also higher, was unfavorable for maintenance, had brought inconvenience to use.
The model utility content
The technical problems to be solved in the utility model is, a kind of loose joint of one-way flow easy to use is provided.
Technical solution of the present utility model is, a kind of loose joint of a kind of one-way flow of following structure is provided, comprises front connector, back joint, loose joint nut, described loose joint nut and back adaptor cup jointing are together, back joint is provided with the dome ring, and the loose joint nut is connected with front connector by screw thread; One-way valve also is installed in the described loose joint, described one-way valve comprises spool and spring, and described spool withstands the front connector mouth of pipe, and an end of described spring is fixed on the spool, the spring link press span also is installed in front connector, and the other end of spring is fixed on the spring link press span; Described spring 3 is in compressive state.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, be provided with one-way valve in loose joint, not be used in one-way valve is installed on the pipeline separately, be convenient to install and use, also saved the operation of using and keeping in repair.
Description of drawings
Fig. 1 is the loose joint embodiment's 1 of a kind of one-way flow of the utility model a structural representation.
Fig. 2 is the loose joint embodiment's 2 of a kind of one-way flow of the utility model a structural representation.
As shown in the figure 1, front connector, 2, the back joint, 3, the loose joint nut, 4, the dome ring, 5, spool, 6, spring, 7, the spring link press span, 8, sealing gasket, 9, the front connector mouth of pipe.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The loose joint of a kind of one-way flow of the present utility model comprises front connector 1, back joint 2, loose joint nut 3, and described loose joint nut 3 connects together with back joint 2, and back joint 2 is provided with dome ring 4, and loose joint nut 3 is connected with front connector 1 by screw thread; One-way valve also is installed in the described loose joint, described one-way valve comprises spool 5 and spring 6, and described spool 5 withstands the front connector mouth of pipe 9, and an end of described spring 6 is fixed on the spool 5, spring link press span 7 also is installed in front connector 1, and the other end of spring 6 is fixed on the spring link press span 7; Described spring 6 is in compressive state; Described spool 5 is shapes such as ball-type, taper.
According to structure of the present utility model, loose joint is connected on the pipeline, collection loose joint and one-way valve are a part, because the effect of one-way valve, the loose joint of this structure is installed, and the liquid in the pipeline then can be realized one-way flow, not be used in one-way valve is installed on the pipeline separately, be convenient to install and use, also saved the operation of using and keeping in repair.
Claims (2)
1. the loose joint of an one-way flow, comprise front connector (1), back joint (2), loose joint nut (3), described loose joint nut (3) connects together with back joint (2), back joint is provided with dome ring (4), loose joint nut (3) is connected with front connector (1) by screw thread, it is characterized in that: one-way valve also is installed in the described loose joint, described one-way valve comprises spool (5) and spring (6), described spool (5) withstands the front connector mouth of pipe (9), one end of described spring (6) is fixed on the spool (5), spring link press span (7) also is installed in front connector (1), and the other end of spring (6) is fixed on the spring link press span (7).
