Abstract
The utility model discloses a unidirectional gas-liquid straight through type rotary joint device. The unidirectional gas-liquid straight through type rotary joint device comprises a tubular body, a cover board, an inlet pipe and a bearing; the unidirectional gas-liquid straight through type rotary joint device is characterized in that inner threads are turned on the inner wall of the left end part of the tubular body, two uniformly-distributed blind holes are formed in the left end plane of a pressure plate which is additionally arranged, outer threads corresponding to the left end part of the tubular body are turned at the outer circle of the pressure plate, three rubber sealing rings are additionally arranged, the inner circle and the outer circle of each rubber sealing ring are respectively and elastically fit with the outer circle of at the left section of the inlet pipe and the inner circle of a left chamber of the tubular body, the inlet pipe is lengthened and extends into the left chamber of the tubular body, the outer threads of the pressure plate are screwed and fixed on the inner threads at the left end part of the tubular body, and after a central hole is sleeved in the end opening at the left section of the inlet pipe, the central hole and the left end plane of the rubber sealing ring are in pressure type elastic fit. The unidirectional gas-liquid straight through type rotary joint device has the advantages that the rubber sealing ring can be stably and tightly compressed in a holoaxial vertical type, a sealing effect is good, the structure is simple, the failure rate is low and the treatment is convenient.
Description
Technical field:
The utility model relates to the gas-liquid piecing devices, particularly a kind of unidirectional gas-liquid straight-through type rotary joint device.
Background technique:
The chemical enterprise operational outfit rotary joint device to gas transmission, transfusion commonly used.Existing rotary joint device is made up of cylinder, cover plate, inlet tube, bearing, sealing slip ring, pressure ring, pressure spring, tubular body, rubbery flat gasket circle, rubber o-ring.In the cylinder sky be provided with separate space Circular Plate, fit fixedly the bearing of inlet tube be nested into the inwall stop portion by the right hole of cylinder, spacing the fixing of shaft block ring of installing by bearing right side upper inlet pipe cylindrical; Inlet tube right part outside thread is used for docking with the breathing pipe pipeline; The inlet tube left port is fitted with sealing slip ring left side, and the sealing slip ring is sleeve-like, and its left periphery is a conical surface; Overlay rubber seal on the conical surface; Rubber seal left side and rubbery flat gasket circle are fitted, and rubbery flat gasket circle cylindrical elastic sleeve is combined in the separate space Circular Plate central hole, and rubbery flat gasket circle left side and pressure ring are fitted.The cylinder left end is through cover plate that has the central, threaded hole of bolt, and cover plate central, threaded hole is used for being connected with outer pipe fixing.Between cover plate right side and pressure ring left side, pressure spring is installed, the cover plate right side is fixed with a tubular body and is used for to section location, a pressure spring left side.Pressure ring will seal the compressing of slip ring right side on the inlet tube left side through the pressure spring elastic force, realize circumferential surface friction rotational slide, and two rubber rings are used for sealing, guarantee that fluid is by flowing into chamber, a cylinder left side in the sealed sliding annular distance.On the separate space Circular Plate in the right chamber of cylinder and the inwall between the bearing left side Leak hole is set, discharges from Leak hole when being used for liquid, avoid corroding bearing inner race from the right chamber of seal ring leakage entering.
Rotation break-in meeting between sealing slip ring and the inlet tube both ends of the surface is because the interior particulate of fluid mixes and produces leakage, and this type mechanical seal leakage need change processing, and maintenance cost is higher.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of unidirectional gas-liquid straight-through type rotary joint device is provided.
The scheme of the utility model is: comprise cylinder, cover plate, inlet tube, bearing; It is characterized in that: cylinder left part inwall car is shaped on internal thread; The platen left side of setting up is provided with two blind holes that are uniformly distributed with, and platen cylindrical car is shaped on the outside thread corresponding to the cylinder left part; Other sets up three rubber seal rings, and the rubber seal ring inside and outside circle stretches into buckshot property applying in the inlet tube left side section cylindrical, chamber, a cylinder left side in chamber, a cylinder left side with prolongation respectively; The platen outside thread is twisted to close and is fixed on the internal thread of cylinder left part, and its central borehole jack is the applying of pressure type elasticity with the rubber seal ring left side after going into inlet tube left side section port.
The advantage of the utility model is: platen can holoaxial to the rectilinear rubber seal ring that steadily compresses, good sealing effect, simple in structure, rate of fault is little, and convenient processing.

Embodiment:
The utility model comprises cylinder 4, cover plate 1, inlet tube 6, bearing 5; It is characterized in that: cylinder 4 left part inwall cars are shaped on internal thread; Platen 2 left sides of setting up are provided with two blind holes that are uniformly distributed with, and platen 2 cylindrical cars are shaped on the outside thread corresponding to cylinder 4 left parts; Other sets up three rubber seal rings 3, and rubber seal ring 3 inside and outside circles stretch into buckshot property applying in the inlet tube 6 left side section cylindricals, cylinder 4 left chambeies in cylinder 4 left chambeies with prolongation respectively; Platen 2 outside threads are twisted to close and are fixed on the cylinder 4 left part internal threads, and its central borehole jack is the applying of pressure type elasticity with rubber seal ring 3 left sides after going into inlet tube 6 left side section ports.
Two blind holes in platen 2 left sides are used for the insertion instrument and turn adjusting platen 2.
