Abstract
The utility model relates to a sealing type telescopic device for conduit used for displacement caused by the heat expansion and cold contraction of a conduit, mainly comprising an outer sleeve pipe, a telescopic pipe, a spring propeller, an active ring, a fixed ring and an adjusting screw bolt. Under the action of the spring propeller and the pressure of self medium, the conduit is kept in a sealed state all the time, and in the process of frequent expansion and contraction, the leakage can be avoided. The utility model has the advantages of small size, light weight, simple manufacturing technique, easy assembling, convenient overhauling, low cost and easy heat preservation.
Description
The utility model belongs to the compensation pipeline causes displacement because of expanding with heat and contract with cold a kind of telescopic compensator, and it is applicable to various pipelines such as water delivery, oil transportation, gas transmission.
At present, the spring-backed quill compensator that has a kind of pipeline to be subjected to displacement owing to expanding with heat and contract with cold, it mainly is made of telescopic pipe, outer sleeve, flange, spring and Sealing.This compensator is the elastic compression Sealing that utilizes spring, and it is loose because of the frequently flexible institute of the telescopic pipe Sealing that causes to have overcome old-fashioned slip joint, easily the shortcoming of leaking.But,, make Sealing loose and produce and leak because spring works under high temperature, high pressure for a long time and can follow the string gradually.And the external diameter at telescopic pipe is equipped with a plurality of springs, therefore, and assembling difficulty, inconvenience maintenance.Its volume is big simultaneously, the cost height.
The purpose of this utility model is to be to provide a kind of sealed pipe expansion bend, and it can utilize the pressure of spring propulsion and self medium simultaneously, Sealing is compressed sealing.
Its concrete solution is: pack into the inner chamber of outer sleeve of the end that telescopic pipe is had a guide pad makes between the inner chamber arm of this outer sleeve and the telescopic pipe outer arm and forms a toroidal cavity.Active ring, Sealing, spring propulsion and retainer ring are housed in this toroidal cavity successively.Can utilize the adjusting bolt spring propulsion to be compressed by the screw that is distributed on retainer ring, make it produce a pressure, utilize in the pipeline be full of the pressure chamber self medium again, give Sealing one pressure with opposite direction to Sealing, above-mentioned two kinds of pressure compress Sealing simultaneously, thereby seal.
Moreover spring propulsion is to flexibly connect in aggregates with screw by spring and the upper and lower pressing plate that has a spring seat.
Specific embodiment of the utility model is illustrated in conjunction with the accompanying drawings:
Fig. 1 is the plan view of expansion bend.
Fig. 2 is the A-A sectional view of expansion bend.
In Fig. 1 and Fig. 2, an end of outer sleeve (12) is by sealing ring (13) and connecting tube (14) welding.Capping (2) is equipped with in its other end, makes outer sleeve (12) be closed state, and at the end that this end has a guide pad (11) with telescopic pipe (1) its inner chamber of packing into, makes between the outer arm of the inner chamber arm of outer sleeve and telescopic pipe and forms a toroidal cavity.The active ring (9) that is slidingly matched with it is housed in this cavity successively, with the Sealing (8) that materials such as asbestos, rubber asbestos, rubber are made, spring propulsion and be anchored on retainer ring (4) on the outer sleeve (12) with screw (15).And spring propulsion flexibly connects with screw by top board (5), press table (7) and a plurality of spring (6) and is integral, and is slidingly matched with outer sleeve inner chamber arm.Utilize adjusting bolt (3) propulsion device to be compressed by the screw that is distributed on the retainer ring (4), make it produce pressure to Sealing (8), the other end at outer sleeve (12) inner chamber is pressure medium chamber (10), be full of self medium in the pipeline in it, this medium is given Sealing one compensatory pressure by active ring (9) in the opposite direction.Under the effect of above-mentioned two kinds of pressure, Sealing (8) is compressed, thereby realize sealing.Simultaneously,, compensate because of cold and hot and make the caused displacement of pipe deforming, make it to be in all the time sealing state by active ring (9), elastomer seal (8), spring propulsion one covering device.
Because the outer tube inner chamber of this expansion bend is equipped with the Monolithic spring propeller that flexibly connects, and utilizes the pressure of this propeller and self medium, simultaneously seal is compressed, seals. So its good sealing effect. Simultaneously, its volume is little, and is in light weight, and manufacturing process is simple, easily assembling, and maintenance is convenient, and cost is low, and easily insulation.
Claims (3)
1, a kind of sealed pipe expansion bend, have outer sleeve, telescopic pipe, an end that it is characterized in that telescopic pipe (1) has guide pad (11), and with pack into the inner chamber of outer sleeve (12) of its end, in the toroidal cavity that between forms, active ring (9), Sealing (8), spring propulsion and retainer ring (4) are housed, spring propulsion presses down tight seal (8) in the effect of regulating bolt (3), and self pressure medium in pressure chamber (10) compresses Sealing (8) again in the opposite direction.
2, expansion bend as claimed in claim 1 is characterized in that spring propulsion is flexibly connected whole by top board (5), press table (7) and spring (6).
3, expansion bend as claimed in claim 1 is characterized in that retainer ring (4) is stable fixing by screw (15) and outer sleeve (12), is evenly equipped with screw on it.
