Description
Technical field
This utility model relates to a kind of expansion joint, particularly relates to a kind of online anti-blocking warning expansion joint of high pressure circulating gas.
Background technology
Technique and the design condition of chemical plant installations recycle compressor high pressure circulating gas line are the harshest, owing to its medium is inflammable, explosive, therefore design pressure is higher, reach 3.2～4.4Mpa, for increasing security requirement ripple pipe racks alarm device, owing to velocity of medium is higher, and for preventing material from gathering, inside lining sleeve is designed with particular/special requirement, existing online warning expansion joint is all to use to quote micro-pipe pressure and measure, there is the advantage of simple in structure and low in cost, and security performance is also ideal.But, owing to being the recycle compressor high pressure circulating gas line of chemical plant installations, need when being necessary pipeline is overhauled, particularly environmental factors very likely in-line contains some chemical industry material, easily the alarm device that carries on corrugated tube is produced blocking, and then cannot correctly gather pressure retarded warning and the most or not, production safety is brought huge potential risk, the corrugated tube carrying alarm device of prior art does not the most possess this kind of function, it is therefore necessary to develop the expansion joint of a kind of online anti-blocking warning to adapt to the safety requirements in market.
Summary of the invention
This utility model overcomes shortcoming of the prior art, it is provided that a kind of online anti-blocking warning expansion joint of high pressure circulating gas.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: a kind of online anti-blocking warning expansion joint of high pressure circulating gas, including corrugated tube, shell ring, flange and inside lining sleeve, the two ends of described corrugated tube are connected with shell ring respectively, the external port of described shell ring adpting flange respectively, described inside lining sleeve one end is connected to flange, the other end is placed in inside the shell ring of the other end through the internal sleeve of corrugated tube, certain gap is there is between described inside lining sleeve and shell ring, described shell ring is provided with warning hole on inside lining sleeve correspondence position, described warning hole is communicated in the warning pipe being arranged on outside shell ring, described warning hole is coated with anti-block apparatus in shell ring inwall side.
As preferably, described corrugated tube uses trilaminate structure.
As preferably, described anti-block apparatus includes anti-blocking coverage block and fixed mount, described fixed mount to be arranged in around warning hole being fixed on the inwall of shell ring, described fixed mount is provided with anti-blocking coverage block.
As preferably, described anti-blocking coverage block is glass fiber filter cotton square.
As preferably, the height of described fixed mount is less than the clearance height between inside lining sleeve and shell ring.
As preferably, described fixed mount is provided with passage.
As preferably, the outer cover of described corrugated tube is equipped with firm ring.
As preferably, the quantity of described firm ring is provided with a firm ring for every 3 pitch of waves on corrugated tube.
Compared with prior art, the utility model has the advantages that: owing to corrugated tube have employed trilaminate structure, and every 3 pitch of waves are provided with a firm ring, greatly strengthen the safety coefficient enhancing bellows expansion joint self-operating safety；Fixed mount and glass fiber filter cotton combinations of blocks cover warning hole, increase pipeline pressure gas circuit pass, can efficiently avoid the warning hole plug hidden danger under chemical environment, and the effectiveness for warning system provides safety guarantee；Fixed mount is provided with passage, and the height of fixed mount, less than the clearance height between inside lining sleeve and shell ring, has ensured the performance that pipeline pressure is penetrated in warning hole, it is ensured that the accuracy of pressure detecting；This utility model simple structure, with low cost, easy to process, it is possible to be adapted to various chemical pipeline online pressure detecting place.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
nullAs shown in FIG. 1 to 3，A kind of online anti-blocking warning expansion joint of high pressure circulating gas，Including corrugated tube 3、Shell ring 2、Flange 1 and inside lining sleeve 6，Described corrugated tube 3 uses trilaminate structure，The two ends of described corrugated tube 3 are connected with shell ring 2 respectively，The external port of described shell ring 2 adpting flange 1 respectively，Described inside lining sleeve 6 one end is connected to flange 1，The other end is placed in inside the shell ring 2 of the other end through the internal sleeve of corrugated tube 3，Certain gap is there is between described inside lining sleeve 6 and shell ring 2，Described shell ring 2 is provided with warning hole on inside lining sleeve 6 correspondence position，Described warning hole is communicated in the warning pipe 5 being arranged on outside shell ring 2，Described warning hole is coated with anti-block apparatus in shell ring 2 inwall side，Described anti-block apparatus includes anti-blocking coverage block (4) and fixed mount (9)，Described fixed mount 9 is arranged on the inwall being fixed on shell ring 2 around warning hole，Anti-blocking coverage block 4 is installed on described fixed mount 9，Described anti-blocking coverage block 4 is glass fiber filter cotton square，The height of described fixed mount 9 is less than the clearance height between inside lining sleeve 6 and shell ring 2，Described fixed mount 9 is provided with passage，The outer cover of described corrugated tube 3 is equipped with firm ring 7，Described firm ring 7 every 3 pitch of waves on corrugated tube 3 are provided with a firm ring 7.
In the present embodiment, owing to corrugated tube 3 have employed trilaminate structure, and 3 pitch of waves every on corrugated tube 3 are provided with a firm ring 7, greatly strengthen the safety coefficient enhancing bellows expansion joint self-operating safety；The combined covering of fixed mount 9 and glass fiber filter cotton square is on warning hole, increase pipeline pressure gas circuit pass, various possible tamper in pipeline can only adsorb on glass fiber filter cotton square, whole glass fiber filter cotton square cannot be blocked completely, can efficiently avoid the warning hole plug hidden danger under chemical environment, the effectiveness for warning system provides safety guarantee；And being provided with passage on fixed mount 9, the height of fixed mount 9, less than the clearance height between inside lining sleeve 6 and shell ring 2, has ensured the performance that pipeline pressure is penetrated in warning hole, it is ensured that the accuracy of pressure detecting；This utility model simple structure, with low cost, easy to process, it is possible to be adapted to various chemical pipeline online pressure detecting place.
