Abstract

The utility model relates to a pour plug type non-medium thrust compensator relating to a pipe compensator, and the compensator is that a sealed filler chamber is equipped at the external of the compensation pipe. The sealed chamber is a filler ring is assembled at the external of the compensation pipe, the filler chamber and the filler ring position the flange, the flange is pressed, and they are connected fixedly by a connection fixing device. The inner diameter of the other end of the compensation pipe is the same as the inner diameter of the circular pushed plate equipped in the conical pipe, and the two are fixed together; the inner diameter of the other end of the conical pipe is the same as the inner diameter of the compensation pipe. The compensator overcomes the pushing force of the medium in conveyance; the compensator adopts chemical sealing materials to seal, so the compensator is convenient and easy to repair.

Description

Pour plug type non-medium thrust compensator

Notes plug formula does not have the medium thrust compensator and belongs to pipeline compensator, relates in particular to the compensator of carrying in the heat distribution pipeline with certain heat medium.

The compensator that uses can't solve the thrust problem that exists in the pipeline at present, I had once disclosed a kind of direct current type medium thrustless compensator in patent 92231299.0 for this reason, this compensator includes three telescopic pipes, annular steam chest overcoat, filler chamber etc., this compensator has solved the thrust problem that exists in the pipeline, but because this equipment has three sealed chamber, and each chamber sky all adopts mechanical seal, therefore in long-term the use in the steam chest water easy-storing cause the damage of sealing material, can keep in repair if maintenance need stop whole transporting system again, this causes damage to production.

It is more simple that the purpose of this utility model then provides a kind of structure, and the maintenance of being more convenient for adopts a kind of notes plug formula of chemical sealant sealing not have the medium thrust compensator.

The utility model is achieved through the following technical solutions: its outer sleeve connects mutually with telescopic pipe, telescopic pipe links to each other with Taper Pipe, a stuffing box packing chamber is arranged outside telescopic pipe, consisting of of sealing filler chamber is equipped with insertion ring and enclosed and supported flange with the filler chamber that insertion ring closely links to each other outside telescopic pipe, at the insertion ring outer fixing locating flange is arranged, this locating flange is fastening by connecting securing means and compressing the method connection, near outside the telescopic pipe of outer sleeve part the seal ring that closed chamber is sealed is being housed, the annular compression plate that the other end of telescopic pipe is identical with its internal diameter with internal diameter is fixed together, and should be assemblied in the Taper Pipe by the annular compression plate, the other end internal diameter size of Taper Pipe is identical with the telescopic pipe internal diameter, preferably the part identical with the telescopic pipe internal diameter has certain length, have the injecting hole on filler chamber's circle, these injecting holes are preferably two, on its hole stopper are housed.

This notes plug formula does not have the medium thrust compensator, because of having fixed an annular compression plate at telescopic pipe one end, make the axis projection face pressure medium annular stress surface that equates with the telescopic pipe internal diameter occur, when transmitting high temperature media, the suffered pressure of telescopic pipe is offset fully, when the medium temperature that transmits raises or ambient temperature when rising, only produce axial elongation or contraction, and do not have medium thrust, this compensator only has a stuffing box packing chamber, promptly simple in structure, be convenient to maintenance, sealing compound is a Chemicals, directly injects from the injecting hole and then is full of whole closed chamber, and solidify rapidly to reach sealing, very easy to use.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is embodiment's a half sectional view.

Embodiment: in Fig. 1, compensator has an outer sleeve 3, its end has a diameter to be slightly smaller than the ring-shaped step N of its external diameter, be equipped with telescopic pipe 12 in this end, telescopic pipe 12 is outer by an insertion ring 4 is housed, one end of insertion ring 4 is stuck on the ring-shaped step N of outer sleeve 3, and be locating face with this step end face N, the outside of insertion ring 4 be equipped with it for friction tight locating flange 10 ' and both exterior edge faces in same plane, the telescopic pipe 12 outer filler chamber's circles 9 that also are equipped with, the end face M of this filler chamber circle 9 and the end face M ' close proximity of insertion ring 4, the H face and supported flange 10 close proximity of the other end of filler chamber's circle 9, locating flange 10 ', filler chamber's circle 9 passes through bolt 7 with supported flange 10, nut 6 and packing ring 6 ' they are tightened together, connect locking method and also can adopt other forms, the connection between the above assembly makes this compensator form a stuffing box packing chamber 15.Near outside the telescopic pipe 12 of outer sleeve 3 parts the seal ring 5 that stuffing box packing chamber 15 is sealed is being housed.Have on the filler chamber circle 9 the injecting hole 8 of injecting sealing compound '.This injecting hole 8 ' preferably has two, injecting hole 8 ' on bolt shape plug 8 is housed, the other end of telescopic pipe 12 and annular compression plate 13 weld together, the inside diameter D of these annular compression plate 13 inside diameter D and telescopic pipe 12 ' measure-alike, this annular compression plate 13 is fixed in the Taper Pipe 14, and the other end of Taper Pipe 14 is the internal diameter straight-run of pipe identical with the telescopic pipe internal diameter.Its length is L.

For the ease of connecting, before this compensator, be added with reducer 1 and connect telescopic pipe 2 with the medium transport pipeline.
