Abstract
The utility model discloses a pipe flange pressure-bearing leakage-stoppage groove type sealing clamp, which is designed for realizing the one-time success of pressure-bearing leakage stoppage and ensuring the safe operation of pipes. The sealing clamp is a circular clamp formed by two semicircular clamping rings, wherein the clamping rings are evenly provided with sealant injecting holes connected with plug valves, the inner circumferential surfaces of the clamping rings are provided with semicircular grooves, and the two clamping rings are connected with fixing members through connecting pin lugs arranged on the outer circumferential surfaces of the clamping rings. The sealing clamp can cover the leakage point of the flange without destroying the sealing of the original structure, establishes a new sealing cavity, and injects sealant into the cavity, thus the sealant is solidified under the action of heat after a certain period of time, thereby realizing the plugging purpose. The sealing clamp can realize the one-time success of pressure-bearing leakage stoppage, has high efficiency and good effect, and ensures the safe operation of pipes. The sealing clamp can be manufactured in series, and has the advantages of simple processing, low cost and wide application range.
Description
Technical field
The utility model relates to a kind of piping flange pressure sealing groove type seal clamp, belongs to technical field.
Background technique
Along with developing rapidly of China's Petrochemical, enterprise is gradually to continization and maximization transition, and production technology is also in the operating mode development to high temperature, high pressure and various materials reaction.The production requirement device systems safety of continization, the stable and normal operation in long period ground.Yet the piping flange in process units is much system share pipeline, after coming into operation for a long time, owing to washing away a variety of causes such as attenuate, under band temperature and operating mode with pressure, likely leak.This class leakage position is often very thin, can not adopt conventional method leak sealing, and shut-down (breakdown) mainteance at any time.
Summary of the invention
The purpose of this utility model is to provide a kind of piping flange pressure sealing groove type seal clamp, and it can guarantee once success of pressure sealing, guarantees pipe safety operation.
Concrete technology contents of the present utility model is as follows:
This seal clamp is the circular clamp being comprised of two semicircular clamping rings.Clamping ring is provided with injecting hole uniform, radially and connection stopcock, clamping ring inner peripheral surface is provided with radially, semicircular groove, clamping ring outer circumferential face two ends are provided with connecting pin ear, connecting pin ear is provided with the pin-and-hole perpendicular to clamping ring center line, and clamping bolt connects tightening nut through the connecting pin ear of two clamping rings.
This clips prodigiosin covers flange leakage point in the situation that not destroying original structure sealing, sets up in new enclosed cavity Bing Xiang chamber and injects sealing compound, and it is solidified under the heat effect of certain hour, realizes shutoff object.This clips prodigiosin is realized the disposable success of pressure sealing, and efficiency is high, effective, guarantees the safe operation of pipeline.This seal clamp can series be made, and processing is simple, and cost is low, applied widely.
Accompanying drawing explanation
Fig. 1 is piping flange pressure sealing groove type seal clamp structural representation.
Fig. 2 is the A-A sectional view in Fig. 1.
Embodiment
Embodiment:
With reference to Fig. 1 and 2, embodiment of the present utility model is further illustrated:
This seal clamp comprises connecting pin ear 1, clamping bolt 2, tightening nut 3, injecting hole 4, groove 5 and clamping ring 6:
This seal clamp is the circular clamp being comprised of two semicircular clamping rings 6.Clamping ring 6 is provided with two four to six uniform, radially, to connect stopcock injecting holes 4, clamping ring 6 inner peripheral surface middle parts are provided with radially, semicircular groove 5, clamping ring 6 outer circumferential face two ends are provided with connecting pin ear 1, connecting pin ear 1 is provided with the pin-and-hole perpendicular to clamping ring 6 center lines, and clamping bolt 2 connects tightening nut 3 through the connecting pin ear 1 of two clamping rings 6.
This seal clamp is divided into the different Multiple Type of internal diameter, is applicable to the flange application of various models.Flange gap≤3mm that this seal clamp is applicable, 4 apertures, injecting hole are 1-2mm.
When leaking appears in flange, at flange outer circumferential face, load onto the clamping ring 6 of this seal clamp matching, by groove 5 alignment flange gaps, and tighten with clamping bolt 2 and tightening nut 3.High-pressure injection plastic rifle is stretched into injecting hole 4, to injecting in the enclosed cavity forming between clamping ring 6 and flange.After injecting, by macroscopical Ocular estimate, soap lye spraying method and instrument detection method, detect, continuous monitoring is finally sealed injecting hole 4 by stopcock without leaking as qualified in 24 hours.After leak stopping is qualified, remove high-pressure injection plastic rifle, this seal clamp is retained on the flange of mending-leakage.
