Abstract

The utility model relates to a filling type disengagement preventing compensator which relates to a heat pipeline compensating device. The utility model is composed of a sleeve pipe, a core pipe, a baffle fence, a press fence and disengagement preventing screw nails, wherein, the core pipe is sheathed in the sleeve pipe and can slide in the sleeve pipe. Sealing fillers are filled between the baffle fence and the press fence for ensuring no leakage between the sleeve pipe and the core pipe. The utility model can prevent disengagement between the sleeve pipe and the core pipe. The safety of a pipe network is ensured. The fillers can be filled through a material filling hole in a sealing system. In addition, the installation of insulation materials is convenient because a disengagement preventing structure is arranged in the filling type compensator. Meanwhile, the cost of the equipment is lowered. The filling compensator has the advantages of compact structure and convenient manufacture and installation.

Description

Can annotate formula anticreep compensator

The utility model relates to a kind of heat supply pipeline compensation device

In heat distribution pipeline,, after pipe network installs, be 1.5 times design of pipe networks pressure because of carrying out the pressure testing test pressure to pipe network because compensator itself is not a rigid body.Under such pressure, cause core pipe and sleeve pipe to throw off sometimes, can influence pipe safety in case throw off.Present pipeline compensator is in design in order to prevent the disengagement of sleeve pipe and core pipe, a flange respectively is installed on core pipe and sleeve pipe, two flanges connect with pull bar, medium can be delivered on the pull bar to the blind plate Driving force of elbow when to the pipe network pressure testing, make whole pipe network form a rigid body, owing to draw to be positioned on jacket exterior and to make the pipeline heat insulating material for external that inconvenience is installed, also make the compensator cost improve.

The purpose of this utility model provides a kind of improved sleeve expansion joint, disconnecting prevention structure itself is housed no longer needs special-purpose disconnecting prevention structure in its outside, make that like this utility model is simple in structure, the saving engineering cost is easy for installation and have special-purpose material hole to make this model utility have good sealing property again.

The purpose of this utility model is achieved in that it includes sleeve pipe, the core pipe, and the anticreep screw, retaining is blue, differential, material hole and sealing system.Sleeve pipe is in the same place with core pipe mutual sheathing, the core pipe can move vertically, left end at the core pipe has screw, screw is contained on the screw, be set with simultaneously retaining orchid and differential on the core pipe, be stuffing box packing between retaining orchid and the differential, stuffing box packing is annotated into by material hole, in addition, the retaining orchid plays again and prevents core pipe and sleeve pipe disengagement.

The utility model has the advantages that, can prevent the disengagement of sleeve pipe and core pipe, filler can not leak by material hole injection assurance pipe network system in the sealing system, and thermal insulating material is easy for installation, saves engineering cost.

Below in conjunction with accompanying drawing enforcement of the present utility model is described further.

Fig. 1 is the utility model structural representation.

See that Fig. 1 concrete structure of the present utility model is as follows, core pipe 2 is sleeved in the sleeve pipe 1 and can axially moves in sleeve pipe 1.Outer cover at core pipe 2 is equipped with retaining blue 4 and differential 3.Differential 3 is fixed together by set screw 6 with sleeve pipe 1.Retaining blue 4 with and differential 3 between be stuffing box packing 8, stuffing box packing 8 is by material hole 5 injections.Left end at core pipe 2 has screw and screw 7 is installed, and when core pipe 2 moves right vertically, thereby makes core pipe 2 and sleeve pipe 1 can not throw off the safety that has guaranteed pipe network mutually because retaining blue 4 blocks screw 7.

Below working principle of the present utility model is described below; Sleeve pipe 1 left side has fixed support to fix during work, when high temperature media enters pipe network, because the pipeline temperature influence certainly will will expand, when pipe expansion, then core pipe 2 will sponge dilation along sleeve pipe 1 axial motion, stuffing box packing 8 is used as the sealing between core 2 and the sleeve pipe 1, guarantee that this compensator does not leak, when pipeline operation a period of time, a smooth compensator sealing part has leakage, then under situation about not stopping production, inject new stuffing box packing, guaranteed the normal operation of pipe network by material hole 5.

The utility model compact structure is made and good sealing effect easy for installation and easy to maintenance, set up defences in this compensator against taking off structure and be convenient to insulation, so the utility model is applicable to and is used as various non-normal temperature pipeline compensators.

Claims

1. can annotate formula anticreep compensation device for one kind, it is characterized in that it is to be made of sleeve pipe, core pipe, retaining orchid, differential, anticreep screw and material hole; The core pipe box is contained in the sleeve pipe and can axially moves in sleeve pipe; Retaining is blue, differential is sleeved on core pipe outside simultaneously, and the anticreep screw is installed in core pipe left end; Differential is fixed together by set screw and sleeve pipe left end; Be stuffing box packing between retaining orchid and the differential, stuffing box packing is injected from material hole.
