Abstract
A hydraulic coupling and hose assembly having self-locking function under decompression comprise a valve body, a valve core, a pipe connection, a connecting sleeve, a baffle board, an adjusting sleeve, a hose, a hose connector, and a restoring spring, wherein one terminal of the valve core which is positioned in the valve body is connected with the restoring spring, one terminal of the baffle board which is positioned in the adjusting sleeve is connected with the restoring spring, and external screws on one side of the valve body is cooperated with the internal screws of the adjusting sleeves to adjust the pressure of the restoring spring. The valve core of the pipe connection is capable of closing the water outlet of the valve body automatically under the function of pressure difference by utilizing the pressure difference formed by hydraulic system leakage or decompression, and the bigger the pressure difference is, the tighter the compacting force is. The utility model has the advantages of simple structure, low cost, easy manufacture, and easy spread.
Description
The utility model belongs to the automatic resist technology of hydraulic transmission field, relates in particular to a kind of hydraulic fitting and hose assembly with decompression auto-lock function.
Hydraulic fitting and hose assembly are links comparatively weak in the whole hydraulic system, in the use occasion that high temperature, high pressure and other continuity are produced, in case serious situation such as leakages, explosion appears in hydraulic hose assembly, will cause that the equipment operation is malfunctioning, tenesmus, leak that oil is met high temperature and serious situation such as burning.
The purpose of this utility model is, a kind of hydraulic fitting and hose assembly with decompression auto-lock function is provided, when particularly occurring decompression situation such as leakage, explosion in the pipeline in Hydraulic Power Transmission System, can carry out self-locking to pipeline and system, reach and avoid because of equipment and security incidents such as system's decompression causes that operation mechanism is malfunctioning, tenesmus or oil liquid leakages.
The technical solution of the utility model is, hydraulic fitting and hose assembly with decompression auto-lock function, comprise valve body, spool, pipe joint, connecting sleeve, dividing plate, adjustment sleeve, flexible pipe, hose coupling, Returnning spring, it is characterized in that the inner chamber of described valve body communicates with the inlet opening of pipe joint and connecting sleeve; Described spool is positioned among the inner chamber of valve body, and an end Returnning spring of spool connects; Described dividing plate is arranged in the inner chamber of adjustment sleeve, and the one end is connected with Returnning spring, and the other end is near the liquid outlet on the adjustment sleeve; The outside thread of described valve body one side and the screw-internal thread fit of adjustment sleeve are to adjust the pressure of Returnning spring between valve body and the adjustment sleeve.
Working principle of the present utility model is, utilizes the pressure difference that forms after hydraulic system leakage or the decompression, makes the liquid outlet of spool on self acting stop valve body under the pressure difference effect of pipe joint, and pressure difference is big more, and it is big more to close tight power.Its technology emphasis is structure and the size at pipe joint.
Hydraulic fitting and hose assembly with decompression auto-lock function described in the utility model, simple in structure, with low cost, be easy to make and promote, practical.Because the employing hydraulic way reaches self-locking, therefore can on hydraulic system, be extensive use of, such as this product of employing on the pipeline of finding in difficult inspection, in case leak decompression locking automatically, and can overhaul immediately, change.And for example on the blast furnace Hydraulic clay gun, use, can reduce oil liquid leakage to greatest extent, avoid accidents such as fire.
Accompanying drawing is the structural representation of hydraulic fitting of the present utility model and hose assembly.
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment
A kind of hydraulic fitting and hose assembly with decompression auto-lock function, comprise valve body 3, spool 4, pipe joint 1, connecting sleeve 2, dividing plate 6, adjustment sleeve 7, flexible pipe 9, hose coupling 8, Returnning spring 5, it is characterized in that the inner chamber 11 of described valve body 3 communicates with the inlet opening 10 of pipe joint 1 and connecting sleeve 2; Described spool 4 is positioned among the inner chamber 11 of valve body 3, and an end Returnning spring 5 of spool 4 connects; Described dividing plate 6 is arranged in the inner chamber 12 of adjustment sleeve 7, and the one end is connected with Returnning spring 5, and the other end is near the liquid outlet 13 on the adjustment sleeve 7; The outside thread of described valve body 3 one sides and the screw-internal thread fit of adjustment sleeve 7 are to adjust the pressure of Returnning spring 5 between valve body 3 and the adjustment sleeve 7.
