Abstract
The utility model relates to a hydraulic quick connector, which overcomes the deficiencies of the present hydraulic quick connector of short service life, oil leakage, more serious environment pollution and the like. The utility model takes the measures that the novel hydraulic quick connector comprises an outer sleeved connector 1, a one-way valve 2, an inner stuffed connector 3, and a seal ring 4 connected on the inner stuffed connector 3; and a retaining ring 5 is mounted on the low-pressure side of the seal ring 4 on the inner stuffed connector 3. The utility model can prolong the service life of the hydraulic quick connector, reduce oil consumption, reduce environment pollution, improve operation rate of a machine train, and reduce manufacturing cost.
Description
Technical field
The utility model relates to rapid pipe joint, specifically belongs to hydraulic quick coupling.
Background technique
Hydraulic quick coupling in use for some time, it is many to produce leakage of oil problem and leak source, makes oil consumption high.By analysis, it is former because unreasonable at the sealing configuration at casting stream fan type section quick release coupling place, promptly do not consider the influence that hydraulic shock causes sealing, only designed a common o-ring groove meeting the inner sealing place soon, a seal ring can only be installed, can't effectively avoid the unusual loss that seals, and there is inevitable hydraulic shock phenomenon in oil hydraulic cylinder in the fan-shaped section cylinder action process when commutation, and the instantaneous pressure that hydraulic shock produces is very big to the influence of seal ring, seal ring is when bearing high compressive load, can embed the gap that seals between coupling part because of producing resiliently deformable, cause the unusual loss of seal ring, finally make quick release coupling behind short-term oil leakage fault will take place frequently using very.It must just can be handled under casting machine shutdown situation, and the unit operation rate is reduced; As make unit continue operation, and then make oil consumption continue to increase, make the cost of production height.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of hydraulic pressure quick release coupling that makes to improve working life, reduces oil consumption, reduces the novel hydraulic rapid pipe joint of environmental pollution.
Realize the technical measures of above-mentioned purpose:
Novel hydraulic rapid pipe joint, the seal ring that connects on the interior plug joint that is connected by the one-way valve in outer bell and spigot joint, the outer bell and spigot joint, with outer bell and spigot joint, the interior plug joint is formed, and its seal ring low voltage side on interior plug joint is equipped with back-up ring.
The utility model compared with prior art, its characteristics: hydraulic pressure quick release coupling working life is increased, reduce oil consumption, reduce environmental pollution, improve the unit operation rate, reduce production costs.
Description of drawings
Fig. 1 is the structural representation of novel hydraulic rapid pipe joint
Embodiment
Be described in detail below in conjunction with accompanying drawing:
Novel hydraulic rapid pipe joint is made up of the seal ring 4 that connects on the one-way valve 2 in outer bell and spigot joint 1, the outer bell and spigot joint 1, the interior plug joint 3 that is connected with outer bell and spigot joint 1, the interior plug joint 3.It is suit back-up ring 5 on the interior plug joint 3 of seal ring 4 low voltage sides.Because back-up ring 5 cooperates with the organic of seal ring 4, make hydraulic quick coupling when operation, seal ring 4 is difficult to produce resiliently deformable again and embeds the gap that seals between coupling part, causes the unusual loss of seal ring 4 and the oil leakage fault phenomenon frequently takes place.
Claims (1)
1. novel hydraulic rapid pipe joint, go up the seal ring (4) that connects by the one-way valve (2) in outer bell and spigot joint (1), the outer bell and spigot joint (1), the interior plug joint (3) that is connected with outer bell and spigot joint (1), interior plug joint (3) and form, it is characterized in that: seal ring (4) low voltage side on interior plug joint (3) is equipped with back-up ring (5).
