Abstract

The utility model discloses a self sealing flexible connection structure capable of lowering abrasion, and relates to connection between a pipeline and a sluice valve. A flexible connecting pipe is arranged between the pipeline and the sluice valve, and the pipeline and the sluice valve are matched with each other in a sealing mode. The self sealing flexible connection structure capable of lowering abrasion adopts a flexible self sealing connection structure to replace a short pipe flange-sealing gasket connection structure in the prior art, when fluid medium with pressure is delivered, a flexible connecting pipeline can play a role in a good damping effect, the medium can smoothly pass through the sluice valve and the flexible connecting pipe, the buffering effect of the flexible connecting pipe reduces abrasion of the medium to the pipeline and greatly reduces overhaul frequency; in the meantime, a flexible connecting pipe self sealing flange is matched with a junk ring in a structural mode, so that the self sealing connection structure is formed between the flexible connecting pipe self sealing flange and the pipeline or the sluice valve, additionally arranging the sealing gasket is unnecessary, and breakdown rate is reduced. The self sealing flexible connection structure capable of lowering abrasion has the advantages of being simple in structure, easy and convenient to install, low in constructional cost, capable of saving materials, lowering maintenance cost and production cost, and improving economic benefit.

Description

A kind of selfsealings flexible connection structure that can effectively reduce wearing and tearing
Technical field
The utility model belongs to the pipe fittings technical field, is specifically related to a kind of simple in structure, simple installation, can effectively reduce the flexible connection structure of wearing and tearing.
Background technique
Being flexible coupling is hollow rubber goods for playing the flexible connection effect between pipeline, is called again the flexible rubber joint, can circumnutate elastomer connector, rubber absorbers etc., has damping effect preferably.Itself and gate valve are widely used in carrying in the pipeline of the flowing medium with certain pressure in mine, metallurgy and chemical industry.In application process is installed, usually adopt be gate valve with hose connector between the structure that is connected by a short tube, generally, short length of tube<=1000mm, be connected with flange plate respectively between gate valve and pipeline, hose connector and pipeline, accompany gasket seal between flange plate and valve.Yet in actual applications, the middle short tube that connects easily weares and teares, and belongs to easy consumption material, pipeline is shorter, weares and teares faster, causes in actual production and overhauls frequently, changes, impact is produced, and has not only increased workman's workload, has also brought the increase of cost of production simultaneously to enterprise.For this reason, develop and a kind ofly can effectively reduce wearing and tearing, can save material again simultaneously, the flexible connection structure that reduces production costs is the key that addresses this problem.
The model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, simple installation, and implementation cost is cheap, can effectively reduce the selfsealings flexible connection structure of wearing and tearing.
The purpose of this utility model is achieved in that and relates to being connected between pipeline and gate valve, between described pipeline and gate valve, hose connector is set, and is sealed and matched each other.
The short tube flange of the flexible selfsealings linkage structure replacement of the utility model employing prior art-sealing gasket linkage structure, when conveying has the flowing medium of pressure, flexibly connect pipeline and can play cushioning effect preferably, medium can be smooth and easy by gate valve and hose connector, the buffer function of flexible steel in flat section tubing has reduced the wearing and tearing of medium to pipeline, greatly reduces repair rate; Simultaneously hose connector selfsealings flange and pressure ring cooperating structure, make its with gate valve or pipeline between formation selfsealings linkage structure, need not additionally to arrange gasket seal, the minimizing rate of fault.The utility model is simple in structure, simple installation, and implementation cost is cheap, has saved material, has reduced maintenance cost and cost of production, has improved economic benefit.
Description of drawings
Fig. 1 is the utility model overall structure cross-sectional schematic;
In figure: 1-pipeline, 2-gate valve, 3-hose connector, 4-bolt, 5-flange plate, 6-pressure ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model relates to being connected between pipeline 1 and gate valve 2, between described pipeline 1 and gate valve 2, hose connector 3 is set, and is sealed and matched each other.Described hose connector 3 ends arrange annular flange connector, are tightly connected by pressure ring 6 and pipeline 1 or gate valve 2.
A kind of in abrasive rubber flexible pipe, can circumnutate rubber flexible pipe or metal net cover structural flexibility pipe of described hose connector 3.
Described hose connector 3 is connected with pipeline 1 or gate valve 2 by pressure ring 6.
Pass through flange plate 5, pressure ring 6, bolt 4 Joints between described hose connector 3 and pipeline 1.
Described hose connector 3 is sealed and matched by pressure ring 6 and gate valve 2.
The thickness of described hose connector 3 tube walls is 1.0 ~ 3.0cm.
Described pressure ring 6 arranges the circular groove that matches with the flange of hose connector.
The described circular groove degree of depth is 1/3 ~ 1/2 of hose connector 3 thickness of flange.
The width of described circular groove and hose connector 3 flange heights adapt.
The utility model working principle and working procedure:
The short tube flange of the flexible selfsealings linkage structure replacement of the utility model employing prior art-sealing gasket linkage structure, when conveying has the flowing medium of pressure, flexibly connect pipeline and can play cushioning effect preferably, medium can be smooth and easy by gate valve and hose connector, the buffer function of flexible steel in flat section tubing has reduced the wearing and tearing of medium to pipeline, greatly reduces repair rate; While hose connector selfsealings flange and pressure ring cooperating structure, pressure ring arranges annular groove and the annular groove degree of depth less than the wall thickness of hose connector, make form the selfsealings linkage structure between itself and gate valve or pipeline and sealing effect better, need not additionally to arrange gasket seal, reduce rate of fault.The utility model connects than the pipeline of prior art, has saved two flange plates, a cover bolt, a slice gasket seal, has reduced cost of production, and simple in structure, and simple installation has reduced maintenance cost, has improved economic benefit.
