Abstract
The utility model relates to a self-enclosing pipeline compensator, which is used in the heat medium pipeline for replacing the present compensator of a sleeve pipe type. The utility model is provided with springs sheathed on a coupling telescopic pipe and the guide bolt of a changeable diameter pipe. When the telescopic pipe extends and shrinks, the springs can pass through a press cover and always compress the sealing filling, and the self seal can be achieved. The utility model has simple and rational structure, convenient use, reliability, convenient maintenance and energy saving.
Description
The utility model is a kind of self sealing pipeline compensator that is used for heat distribution pipeline.
Existing telescopic heat distribution pipeline compensator promotes gland 3 by regulating nut 2 as shown in Figure 1, because the restriction of plate washer 6 compresses stuffing box packing 4, realizes sealing.When steam prolongs arrow A when entering reducer pipe 5 by telescopic pipe 1, telescopic pipe 1 elongation; When stopping to send steam, pipe 1 shortens, and the volume of stuffing box packing 4 is constantly changed, and produces friction, makes the filler wearing and tearing, and the seepage phenomenon easily takes place, and needs the people often to keep in repair, and changes stuffing box packing.
The purpose of this utility model is according to the deficiencies in the prior art, proposes a kind of self sealing pipeline compensator.
The utility model has increased spring attachment on the gland of stuffing box packing, to achieve the above object.
The utility model is to load onto guide blot on Gland, one end of this bolt is fixed on the telescopic pipe, is with spring on the guide blot, gives the certain precompression of spring during mounting spring, make length of spring compressed 15-20mm, and make the telescopic pipe right side surpass baffle plate 15-20mm.When thermal medium passes through, the elongation of heat expansion telescopic pipe, when no medium passed through, telescopic pipe shortened, and the volume of loading pipe 7 constantly changes, because the pressure of spring, filler can be sealed the mouth of pipe automatically.Even when filler is worn, also can guarantee sealability, realize from motive sealing.
The utility model cost is low, and energy saving is easy to use, reliable operation.
Below in conjunction with description of drawings concrete structure of the present utility model and working procedure.
Fig. 2 is a structural drawing of the present utility model.Among the figure 1, the heat expansion telescopic pipe; 2, nut; 3, gland; 4, filler; 5, become through pipe; 6, plate washer; 7, loading pipe; 8, guide blot; 9, fixed plate; 10, spring.A, direction of heat flow.Telescopic pipe 1 and reducer pipe 5 is rack-mount, make the heat expansion telescopic pipe surpass baffle plate 6, regulate nut 2, make the length of spring compressed on the guide blot 8.The concentricity temperature difference of telescopic pipe compensator and pipeline is no more than ± 2mm.Thermal medium flows through compensator along arrow A among the figure, and the volume of loading pipe 7 changes, because the pressure of spring 10, filler 4 is automatically with ferrule.
Claims (2)
1, for the pipeline of carrying thermal medium, steam line particularly, the self sealing pipeline compensator that expanding with heat and contract with cold of tube wall compensated, this compensator has a telescopic pipe 1 to insert change through managing in 2, have between two pipes gland 2 is arranged on stuffing box packing 4, the filler, plate washer 6 is arranged at the filler bottom, it is characterized in that being equipped with on the gland guide blot 8, is with spring 10 on the guide blot bar 8.
2, compensator according to claim 1 is characterized in that spring 10 is compressed 15-20mm, and the length that telescopic pipe 1 inserts plate washer 6 is 15-20mm.
