Description

Can the shaping end socket of self-bleeding insulating tube

Technical field

The utility model relates to the parts, particularly one applied in a kind of insulating tube forming process can the shaping end socket of self-bleeding insulating tube.

Background technology

Existing heat supply insulating tube comprises the work core pipe being positioned at inner side, the outer pillar of middle part with filled thermal insulation materials mouth is set with in the outside of work core pipe, be provided with multiple even and spaced bracing frame outside between pillar and work core pipe, relatively keep coaxial between outer pillar and work core pipe by bracing frame.Insulation material is had outside between pillar and work core pipe.The insulating tube moulding process of this structure is as follows: first also evenly fix multiple bracing frame at the outside spacers of work core pipe; Middle part is contained in the outside of multiple bracing frame with the outer protective pipe sleeve of filled thermal insulation materials mouth, keeps outer pillar and work core pipe confronting coaxial; The two ends of pillar are provided with end socket outside, i.e. the termination of the tubular space of the outer pillar of shutoff and the formation of work core pipe.Filling-foam insulation material in the tubular space formed by the outside pillar of filled thermal insulation materials mouth and work core pipe, expand gradually after foaming thermal-insulating reaction and extend to two ends, form heat-insulation layer, simultaneously in order to discharge original gas, the lateral wall at pillar two ends offers exhaust outlet, staff during foaming, must be had to observe exhaust outlet at any time, when being about to when there being insulation material discharge, artificial shutoff exhaust outlet, discharges from exhaust outlet to prevent insulation material immediately.This moulding process has following shortcoming: one, manual operation adds the quantity of operator, and because needs are observed and shutoff exhaust outlet, each station manipulation personnel must not be less than 3 people; Two, there is shutoff phenomenon not in time sometimes in manual operation, and foamed material will vomit from exhaust outlet, causes product rejection, also has potential safety hazard to operating personnel; Three, because exhaust outlet is positioned at the side of filling termination, chamber, exhaust effect is not good, has portion gas and is wrapped up by the foamed material reacted rapidly and form pore, affect product quality; Four, production efficiency is low, and production cost is high.

Summary of the invention

In order to overcome the defect that prior art exists, the purpose of this utility model be to provide a kind of structure simple, can smoothly Exhaust Gas, without city operating personnel observation and shutoff, increase work efficiency, reduce production cost, eliminate safe hidden trouble can the shaping end socket of self-bleeding insulating tube.

The type that this practicality is new can the shaping end socket of self-bleeding insulating tube, comprise discoid heat exchanger head, the centre bore matched with insulating tube internal work core pipe is had inside heat exchanger head, heat exchanger head is along the circumferential direction distributed with open-work, venting plug is inlaid with at through-hole position, the bottom surface of venting plug is provided with multiple steam vent, and the diameter of steam vent is 1.2 millimeters ~ 2 millimeters.

The periphery of described venting plug has the edge extended laterally, and described edge rides against on the end face of heat exchanger head; Venting plug is positioned at described open-work with the part of multiple steam vent.

Of the present utility model can the shaping end socket of self-bleeding insulating tube, because itself has degassing function, automatic vent can be realized when outside pillar and work core pipe centre foaming and intumescing, smooth in exhaust, without the need to manual observation and shutoff exhaust outlet, the diameter of each steam vent on venting plug is 1.2 millimeters ~ 2 millimeters, can exhaust be ensured and not leak material (foamed material), intraluminal pressure can be kept again, the density of foam is made to reach product standard requirement, reduce human cost 50%, process-cycle shortens nearly 20%, the quality problems because exhausting problem occurs are stopped, operational security have also been obtained remarkable improvement.Technique is simple, and production efficiency is high.

Detailed description of the invention

As shown in Fig. 1 ~ 5: of the present utility modelly can comprise discoid heat exchanger head 1 by the shaping end socket of self-bleeding insulating tube, inside heat exchanger head 1, there is the centre bore 4 matched with insulating tube internal work core pipe.Heat exchanger head 1 is along the circumferential direction evenly distributed with open-work 5, venting plug 3 is inlaid with at each open-work 5 place, the bottom surface of venting plug 3 is evenly distributed with multiple steam vent 6, the diameter of steam vent 6 is 1.2 millimeters or 1.4 millimeters or 1.6 millimeters or 1.8 millimeters or 2 millimeters, namely between 1.2 millimeters ~ 2 millimeters.

The periphery of venting plug 3 has the edge 7 extended laterally, and edge 7 rides against on the end face of heat exchanger head 1; Venting plug 3 is positioned at open-work 5 with the part of multiple steam vent 6.

Application process is as follows: as shown in Figure 6,7: also evenly fix multiple bracing frame 10 at the outside spacers of work core pipe 8; Middle part is sleeved on the outside of multiple bracing frame 10 with the outer pillar 9 of filled thermal insulation materials mouth 11, keeps outer pillar 9 and work core pipe 8 confronting coaxial; The two ends of pillar 9 all arrange end socket of the present utility model outside, and heat exchanger head 1 is sleeved on work core pipe 8 by centre bore 4; There is seam 2 inner side of heat exchanger head 1, and the termination point casing of outer pillar 9 is contained in the outside of seam 2.By filled thermal insulation materials mouth 11 outwards filled with foaming material between pillar 9 and work core pipe 8, expand to two ends gradually after reaction, gas is discharged smoothly from steam vent 6, can ensure that material (foamed material) is not leaked again in exhaust, keep intraluminal pressure, make the density of foam reach product standard requirement, reduce human cost 50%, process-cycle shortens nearly 20%, and stopped the quality problems because exhausting problem occurs, operational security have also been obtained remarkable improvement.Technique is simple, and production efficiency is high.
