Abstract
The utility model relates to an external press spring style rotary joint, which is composed of a shell 1, an O-shaped seal ring 2, a spherical face ring 3, a heat radiation 4, a spring 5 and a hollow shaft 6. The spring (5) is installed between the external side of the hollow shaft (6) and the heat radiation cover (4). A heat radiation hole is arranged on the heat radiation cover. That the heat radiation hole scatters the hot fluid conducted by the hollow shaft into air avoids the deformation of the spring caused by the heat, makes the spring hold the elasticity, and ensures the tight contact between the spherical face ring (3) and the sphere on the hollow shaft (6). The end face of the heat radiation cover is provided with the O-shaped seal ring, has excellent sealing, and improves the service life. The fluid is not necessary to flow from the gap of the spring. So the pressure loss is small and the flow rate is big.
Description
The utility model relates to a kind of fixing outer pressure spring type swivel joint engineering goods of pipeline conversion of connection device swivelling pipe road direction when being used for conveyance fluid.
Swivel joint one end is connected with rotation pipeline on the equipment, and an end joins with the pipeline of fixing accommodating fluid, has fluid to flow through in the pipeline.Fluid can be liquid, gas or steam.Fluid is transported on the machine by swivel joint.Compensatory, the sealing of swivel joint is directly connected to its working life.
Present known swivel joint is made up of housing, hollow shaft, sphere ring, spring etc.Sphere on the hollow shaft matches with the sphere ring, seals.After the wearing and tearing of sphere ring, be installed in the spring of hollow shaft end in the housing, promote hollow shaft vertically near the sphere ring, the gap that compensate for wear causes.The shortcoming of this kind structure is that spring is installed in hollow shaft end in the housing, when fluid is hot fluid such as deep fat or steam, and the spring temperature distortion, the hollow shaft sphere can not closely contact with the sphere ring, causes the swivel joint leakage and scraps; Spring is installed in the swivel joint fluid outlet, and fluid must flow out from the slit of spring, makes the fluid swivel joint pressure loss of flowing through big, and flow is little.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of novel outer pressure spring type swivel joint is provided, and spring was indeformable when this outer pressure spring type swivel joint was carried hot fluid, made the effectively compensation of sphere ring wearing and tearing back, good seal performance, prolong working life; Reduce fluid pressure loss, flow increases.
The purpose of this utility model is achieved in that
Outer pressure spring type swivel joint is mounting spring between hollow shaft outside and dissipating cover, radiation hole is arranged on the dissipating cover, the heat of the hot fluid of hollow shaft conduction is loose in air, avoid the spring temperature distortion, make spring keep elastic force, guarantee that the sphere ring closely contacts with sphere on the hollow shaft.Add O-ring seals between housing and the hollow shaft, the impurity in the fluid can not be entered in the sphere ring.The dissipating cover end face has the O-ring seals sealing.
The utility model spring is installed on outside the hollow shaft, good seal, and double working life; Fluid needn't flow through from the counterbalance spring slit, and the pressure loss is little, and flow is big.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the sectional drawing according to the outer pressure spring type swivel joint that the utility model proposes.
Describe the details and the working condition of the concrete structure that proposes according to the outer pressure spring type swivel joint of the utility model in detail below in conjunction with accompanying drawing.
Among the figure: 1. housing, 2.O shape seal ring, 3. sphere ring, 4. dissipating cover, 5. spring, 6. hollow shaft.
Outer pressure spring type swivel joint is mounting spring (5) between hollow shaft (6) outside and dissipating cover (4), dissipating cover has radiation hole on (4), the heat of the hot fluid of hollow shaft (6) conduction is loose in air, avoid the spring temperature distortion, make spring keep elastic force, guarantee that sphere ring (3) closely contacts with sphere on the hollow shaft (6), add O-ring seals (2) between housing and the hollow shaft, the impurity in the fluid can not be entered in the sphere ring.The dissipating cover end face has O-ring seals (2) sealing.Good seal prolongs working life.The pressure loss is little, and flow is big.
Claims (4)
1. outer pressure spring type swivel joint is connection device rotation pipeline and fixing tube, conveyance fluid and rotatable device, form by housing, O-ring seals, sphere ring, dissipating cover, spring, hollow shaft, it is characterized in that having dissipating cover, spring is installed between hollow shaft and the dissipating cover, and O-ring seals is installed.
2. it is characterized in that according to claim 1 described outer pressure spring type swivel joint radiation hole is arranged on the dissipating cover.
3. it is characterized in that dissipating cover end face installation O-ring seals according to claim 1 described outer pressure spring type swivel joint.
