Abstract

The utility model particularly relates to a flange type pressure plugging device, which is characterized in that the device comprises an upper pressing plate and a lower pressing plate, sections of the upper pressing plate and the lower pressing plate are semicircular, horizontal bosses are respectively arranged on two sides of the bottom of the upper pressing plate and two sides of the top of the lower pressing plate, the upper pressing plated is connected with the lower pressing plate through bolts, corresponding bolt holes are arranged on the bosses of two sides of the upper plate and the lower plate, and a plurality of semicircular sealing strips are symmetrically arranged on inner walls of the upper pressing plate and the lower pressing plate. The device has the advantages that 1) the device can be operated with the pressure and the temperature, so that leakages can be eliminated without stopping or shut down; 2) dangerous measures including electrical welding, gas welding and the like are not required in the process of leakage eliminating in inflammable and explosive areas; 3) new sealing structures are easy to removed while original structures of devices or pipes are not destroyed, so that subsequent equipment maintenance is facilitated; 4) sealing and plugging with the pressure can be performed without any treatment on leaking positions, and the method is simple, flexible to operate, time-saving, energy-saving, safe and fast; and 5) the device is strong in adaptability, wide in application range and applicable to leakages of all fluid mediums.

Description

Flange pressure sealing device
Technical field
The utility model is specifically related to a kind of flange pressure sealing device.
Background technique
In Ammonia Production, the flange connections of pipeline often leaks, and causes the waste of available gas can cause security incident simultaneously; Flange leakage generally often occurs in the sealing surface place, just can realize leak stopping for the flange of low pressure flange or small amount of leakage through the son of checking card, when high pressure steam or high pressure gas leakage; Gas flow rate is fast, and temperature is high, and son just can not be realized leak stopping through checking card; At this moment just must whole system stop; Flange to leaking repairs or replaces, and frequent the parking influences manufacturing efficiency.
The model utility content
When the purpose of the utility model is to solve existing technology flange generation leakage, do not have specialized pressure sealing device, the maintain and replace flange need stop, and influences the defective of manufacturing efficiency, and a kind of flange pressure sealing device simple in structure, easy to use is provided.
The utility model is realized through following technological scheme:
It is a kind of flange pressure sealing device; It is characterized in that comprising that the cross section is semicircular top board and press table; Top board two bottom sides and both sides, press table top are equipped with horizontally disposed boss; Connect through bolt between top board and the press table, be located at corresponding bolt hole on the boss of top board and press table both sides, the inwall of top board and press table is provided with symmetrically arranged many semicircle Stamping Steel Ribbons.
A preferred version as the utility model: it is square strip projected parts that the boss bottom surface of press table is provided with the cross section, and it is square strip groove that the boss end face of top board is provided with the cross section that matches.
The utlity model has following advantage:
1) band temperature, band press operation do not stop when stopping a leak, do not stop production.
Need not to adopt dangerous way such as electric welding, gas welding when 2) stop a leak in inflammable, explosive zone.
3) do not destroy the original structure of equipment or pipeline, new sealing configuration is readily removable to be removed, for later overhaul of the equipments is provided convenience.
4) leakage position need not done any processing, can be with the means of press seals leak stopping, and method is easy, flexible operation, time saving and energy saving, safe and efficient.
5) adaptability is strong, and applied range is applicable to the leakage of the flowing medium of depositing.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan view of Fig. 1.
Shown in figure: 1 press table; 2 Stamping Steel Ribbons; 3 boss; 4 boss; 5 bolts; 6 top boards; 7 Stamping Steel Ribbons; 8 convexities; 9 grooves.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
Shown in Fig. 1, figure: the cross section of top board 6, press table 1 is semicircle; The both sides of two pressing plates are provided with horizontally disposed boss 3, boss 4; Boss 3, boss 4 connect through bolt 5; The inwall of top board 6, press table 1 is provided with semicircular Stamping Steel Ribbon 7, the Stamping Steel Ribbon 2 of 3 groups of symmetries, and it is square strip projected parts 8 that the bottom surface of the boss 4 of top board 6 is provided with the cross section, and it is square strip groove 9 that the boss end face of press table 1 is provided with corresponding with it cross section.
When the utility model uses, top board 6, press table 1 are encased the flange leakage position, use bolt 5 that top board 6, press table 1 are tightened and get final product pressure sealing.
