Abstract
The utility model discloses a sealant injecting ball compensator belonging to a compensation apparatus for the length of a heat distribution pipeline. The amount of deformation of a heat distribution pipeline caused by the thermal expansion and cooling shrinkage is absorbed through the rotation and the fold of a ball. The inner stress of the pipeline is released. The sealant injecting ball compensator is composed of a device body 1, a support ring 2, a high pressure injection port 3, an injectable sealant 4, a regulating pressing cover 5, a ball 6, etc. The disadvantages existing in an ordinary ball compensator that the seal easily generates deformation, ageing and crushing, and the sealing effect is lost; when a leakage occurs, the production needs to be stopped; the disassembly, the maintenance and the use are inconvenient are overcome. The sealant injecting ball compensator adopts the structure that the support and the seal are separated. The utility model has the advantages of high rigidity, long service life, convenience and simpleness, easy application, safe operation, little abrasion, stable sealing performance, safety and good economical performance. The sealant injecting ball compensator can replenish and inject fresh sealants with temperature and pressure. The production does not need to be stopped.
Description
The utility model relates to the heat-net-pipeline compensator, particularly relates to the high temperature, high pressure, the bigbore spherical compensator that are used for industry pipelines such as thermoelectricity plant's concentrated supply of heating in the city petrochemical industry.
The spherical compensator that uses in general heat-net-pipeline is to adopt seal ring ball float technology.Seal ring need bear the effect of the alternating stresses such as axial pressure that thermal stretching produced of gravity, pressure medium and two spherical compensator connecting tubes of spheroid deadweight, part connecting tube.Therefore, seal ring is easy to generate distortion, aging, conquassation and loses sealing effect and cause leakage contribution to use, the dismounting seal ring maintenance that needs often to stop production, and simultaneously, because this spherical compensator has two flanges and is connected with pipeline, interface easily produces leakage.And heat diffusion area is big, and the thermal loss of pipeline is big, the energy of waste pipeline carrier, thus the Security of pipe-line system and Economy are reduced.
The purpose of this utility model is to overcome the shortcoming that exists in the existing spherical compensator.A kind of simple spherical compensator sealing configuration is provided, can be with the temperate zone to press the maintenance that do not stop production.
With accompanying drawing the technical solution of the utility model is described below.
The mark sequence number is expressed as follows respectively in the accompanying drawing: 1. body, 2. bearing ring, 3. the high pressure inlet, 4. can annotate sealing compound, 5. regulate gland, 6. spheroid.
Description of drawings, the utility model inject sealing compound formula spherical compensator and be provided with two bearing rings 2 in bodies 1., in order to supporting spheroid 6, adjust glade plane space between spheroid and the bearing ring by regulating gland 5., constitute Zhi Chengfu.Utilize the space of the bearing ring formation on body, spheroid and both sides, inject sealing compound from high pressure inlet 3., constitute sealing pair, realize sealing function, find that in the pipeline running there is the seepage phenomenon part, under situation about not stopping production, replenish the fresh sealing compound of injection from the high pressure inlet, can stop a leak, when using described injection sealing compound formula spherical compensator, spherical compensator is installed in the pipeline, utilize the rotation folding of spheroid to bend the heat distribution pipeline dilatation amount that absorbs, the internal stress of release pipeline, thereby the safe operation of assurance heat distribution pipeline.
Embodiment: make body, spheroid with refractory metal material.Make bearing ring with aluminium bronze, spheroid and bearing ring are placed body, utilize the gap of regulating between gland adjustment spheroid and the bearing ring.The gap is 0.30～0.40 millimeter, injects sealing compound from the high pressure inlet then, makes the interior sealing compound pressure of packing cavity reach 20MPa and can guarantee sealing.
The utility model injects sealing compound formula spherical compensator and adopts supporting and the isolated structure of sealing, good rigidly, and load and system's alternating stress are not born in the sealing position, it is little to wear and tear, seal very reliably, and sealing compound under high pressure has plasticity, can realize that band temperature, band press, the maintenance that do not stop production reaches the purpose of long-term use.
Claims (1)
1, a kind of injection sealing compound formula spherical compensator, comprise body/, regulate gland 5, spheroid 6 it is characterized in that body/in be provided with bearing ring 2, regulate gland 5.Be provided with the high pressure inlet 3 of some at body/excircle, spheroid 6 is arranged between two bearing rings 2 of body/interior, can annotate sealing compound from high pressure inlet 3 inject bodies/, in the Seal cage that forms of bearing ring 2, spheroid 6, constitute the support motion pair by spheroid 6 and two bearing rings 2, spheroid 6 with can annotate sealing compound 4 and constitute sealing pairs.
