Abstract
A sealing fixture for flange connection pertains to the flange connection field, which comprises two clips arranged face to face and connected in cooperation with the flange, and the retaining tongue of each clip is fastened between two flanges; the utility model is characterized in that an inner hole formed by the retaining tongues is provided with an elastic sealing ring whose thickness is more than the distance between two flanges, and the elastic sealing ring is provided with a sealant-injected hole. Because of the adoption of the elastic sealing ring of the utility model, and taking use of the good elasticity thereof, the problems of unequal flange distance and the sealant vulcanized shrinkage are solved, and the utility model has good sealing effect; the utility model enables a low clip processing and measurement requirements, and avoids effectively the medium leakage so as to maintain normal production and prevent environment pollution; the utility model can be widely applied to the sealing and plugging connection of a flange or a big valve cap with a distance over 5mm.
Description
Technical field
The utility model belongs to flange and connects the field, is specifically related to a kind of seal arrangement with seal ring.
Technical background
At present, be applied in the flange seal of the medium transport pipe of industries such as petrochemical industry, chemical fertilizer, medicine, generally adopt the jig sealing.This kind jig cooperates the clamp of two band block tongues that connect to form by the outer circumferential face that is arranged on flange and with flange, the block tongue on each clamp is stuck between two flanges, injects sealer between block tongue and flange gasket.There is following defective in this kind jig in application:
(1) because two joining flange spacings may be unequal in actual applications, thereby causes not waiting of the clamp block tongue thickness that is mated, both caused the difficulty of clamp manufacturing, cause easily that also medium reveals.
(2) sealer between block tongue and flange gasket causes volume shrinkage owing to vulcanizing, but the clamp block tongue is a rigid construction, thereby easily causes sealing load decline in the Seal cage, thereby causes the medium leakage phenomenon.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of sealing jig that flange connects that is used for of good sealing effect, its scheme that adopts is: design a kind of sealing jig that flange connects that is used for, it comprise cooperate with flange connect and be two clamps that are oppositely arranged, the block tongue on each clamp is stuck between two flanges, in the endoporus that feature is made up of block tongue the elastic seal ring of thickness greater than two flange spacings is set, offers hole for injecting glue on the elastic seal ring.
The utility model, has compensated because the medium leakage problem that contraction causes, good sealing effect are vulcanized in not waiting with sealer of flange spacing by means of the good harmomegathus elasticity of elastic seal ring owing to adopted elastic seal ring; Processing, measurement requirement to clamp are low, and can avoid effectively, in time influences normal operation in process units ground and environmental pollution because of the medium leakage; Can be widely used in flange or the valve big lid sealing and plugging connection of spacing greater than 5mm.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model embodiment's a structural representation;
Embodiment
As shown in the figure: clamp 2,8 cooperates connection with flange 4,5 respectively, block tongue on the clamp 2,8 is stuck between the flange 4,5, in the endoporus of being made up of block tongue an elastic seal ring 6 is set, the thickness of elastic seal ring 6 (axial dimension) is slightly larger than the end distance of flange 4,5.Like this, when elastic seal ring 6 is installed, produced certain sealing load between elastic seal ring and the end face of flange.By injecting sealer 3 in injecting glue through hole on the clamp 2 and the space (Seal cage) of elastic seal ring between elastic seal ring 6 and pad 7, sealer 3 is to flowing all around and filling up Seal cage by rubber injecting valve 1, and the Seal cage internal pressure raises gradually.When reaching certain pressure, force elastic seal ring 3 distortion.Axially can not produce displacement because of flange 4,5, elastic seal ring can only be along the radial deformation of flange 4,5, axial generation sealing load (this pressure is proportional to the pressure of sealer in the Seal cage) at flange makes elastic seal ring 6 be pressed on the end face of flange tightly.Thereby played seal action well.When sealer 3 caused volume shrinkage because of sulfuration, because elastic seal ring 6 has elasticity, thereby its resilience can compensate the volume shrinkage that causes because of the sealer sulfuration, makes the Seal cage internal pressure descend and descend less or not that the density reduction of sealer seldom.Because sealing load is all the time greater than the leakage pressure of medium, thereby reached desirable sealing purpose.
Claims (1)
1. one kind is used for the sealing jig that flange connects, comprise cooperate with flange connect and be two clamps that are oppositely arranged, the block tongue on each clamp is stuck between two flanges, the elastic seal ring of thickness greater than two flange spacings is set in the endoporus that it is characterized in that being made up of block tongue, offers hole for injecting glue on the elastic seal ring.
