Abstract
The utility model relates to a flow guide type air duct rubber compensator comprising two paired flanges and flexible rubber compensating pipelines which are sheathed in the paired flanges; two ends of the flexible rubber compensating pipelines are provided with flanging-shaped washers; one end of the flexible rubber compensating pipeline is inserted into a matched flow guide pipe; the tail part of the flow guide pipe is provided with a ring-shaped flanging which is matched with the paired flange closely installed therewith. The flow guide type air duct rubber compensator has long service life, good sealing performance and convenient transportation and installation and and is beneficial to promotion and application.
Description
One, technical field
The utility model relates to a kind of pipeline compensator, particularly relates to a kind of flow guide type air channel rubber compensator.
Two, background technique
Pipeline compensator is an imperative equipment during national pipe network is laid, and present domestic main employing bushing type expansion bend is according to the concrete structure difference; the bushing type expansion bend that has is merely able to realize axial rising-heat contracting-cold compensation; the spherical compensator that has is merely able to realize angle compensation, and still, their ubiquitous defectives are: reveal easily; the Maintenance and Repair workload is big; when amount of leakage needs repairing greatly, need to shut down, stop work so very big terminal use that influences; and long in time limit, the maintenance cost height.And existing pipeline compensator is not provided with anti-pull off body, when compensation rate is excessive, causes sleeve pipe and core pipe to break away from, and forms big leakage, needs shutdown maintenance, causes bigger loss.
Shortcomings such as the telescopic pipeline compensator that uses adopts fillers such as asbestos, graphite that inner and outer sleeves is sealed mostly at present, has poor sealing performance, leaks easily, and easy to wear, working life is short.
Three, model utility content
The purpose of this utility model is in order to address the above problem, a kind of good seal performance to be provided, to be convenient to transportation, the flow guide type air channel rubber compensator of being convenient to install.
The technical solution of the utility model is: a kind of flow guide type air channel rubber compensator, contain two companion flanges, be sleeved on the flexible rubber compensation pipeline in the companion flange, this flexible rubber compensation pipe ends is provided with flange shape packing ring, it is characterized in that: an end of described flexible rubber compensation pipeline is inserted with the honeycomb duct of coupling, this honeycomb duct afterbody is provided with annular flange, and this flange and its are near the companion flange coupling of installing.
Be equipped with the construction bolt hole on described two companion flanges.
Described annular flange is provided with and its bolt hole near construction bolt hole coupling on the companion flange of installing.
The side of described companion flange is fixedly connected with two transportation positioning tie bars at least, and this transportation positioning tie bar is approximate " door " font reinforcing bar bent part, and two leg lower ends of this pull bar are fixedly connected on two companion flange sides respectively.
The beneficial effects of the utility model
Flow guide type of the present utility model air channel rubber compensator is provided with guide plate, and this guide plate can be kept apart delivered inside medium and flexible rubber compensation pipeline, can reduce the wearing and tearing of flexible rubber compensation pipeline, prolongs its working life.
Adopt flexible rubber compensation pipeline, compare with original pipe-type compensator, its sealing effect improves greatly, and the two ends of this flexible rubber compensation pipeline also are provided with flange formula packing ring, can further improve its sealing effect.
Adopt the transportation positioning tie bar, this product two companion flange stationary positioned have before use been connected, be convenient to transportation and carrying, can also improve the on-the-spot installation efficiency of back.
Four, description of drawings
Fig. 1 is the structural representation of this flow guide type air channel rubber compensator
Fig. 2 is the user mode structural representation of this flow guide type air channel rubber compensator
Five, embodiment
Referring to Fig. 1, Fig. 2,1. honeycomb ducts among the figure, 2. companion flange, 3. the transportation positioning tie bar, 4. the flexible rubber expansion pipe, 5. connecting bolt, 6. piping flange.
A kind of flow guide type air channel rubber compensator among the figure, contain two companion flanges, be sleeved on the flexible rubber compensation pipeline in the companion flange, this flexible rubber compensation pipe ends is provided with flange shape packing ring, it is characterized in that: an end of described flexible rubber compensation pipeline is inserted with the honeycomb duct of coupling, this honeycomb duct afterbody is provided with annular flange, and this flange and its are near the companion flange coupling of installing.Be equipped with the construction bolt hole on described two companion flanges.Described annular flange is provided with and its bolt hole near construction bolt hole coupling on the companion flange of installing.The side of described companion flange is fixedly connected with two transportation positioning tie bars at least, and this transportation positioning tie bar is approximate " door " font reinforcing bar bent part, and two leg lower ends of this pull bar are fixedly connected on two companion flange sides respectively.
In the time of installation that the direction of insertion of honeycomb duct is corresponding with the media flow direction, two companion flanges are connected with bolt with two piping flanges respectively, destroy the transportation positioning tie bar subsequently, the flow guide type air channel rubber compensator of this model utility promptly enters user mode.
