Abstract
The utility model discloses a temperature-self-controlled thermal melt jointing device, which comprises a pipe melt joint, a fitting melt joint, a left and a right heat conducting plates, brackets and a PTC heating ceramic body which is arranged between the left and the right heat conducting plates, wherein, the pipe melt joint and the fitting melt joint are respectively fixed on both sides of the left and the right heat conducting plates, and the brackets are fixed on the both sides of the left and the right heat conducting plates. The inner parts of the brackets are provided with power cords which are connected with the PTC heating ceramic body. The utility model does not need adopt a temperature control part to regulate temperature, so the phenomenon that the heat conducting plates are broken down because of the too high temperature can not be caused, and the structure of the whole device of the utility model is also simplified greatly.
Description
The utility model relates to the hand-operated tools of sweat soldering, is meant a kind of temp autocontrolled thermoweld unit that is used for connection between the polypropylene PP-R tube and tube accessory, installs more specifically.
It is very general to be made into civilian hot water pipe with polypropylene material, existing be used for the connection between the polypropylene PP-R tube and tube accessory, the thermofusion device of installation mainly comprises nickel filament heat-generating pipe, heat-conducting plate, pipe welded joint, accessory welded joint, temperature control part branch, heat-conducting plate is formed and the nickel filament heat-generating pipe is placed in it by the aluminium alloy casting, pipe welded joint and accessory welded joint place the heat-conducting plate both sides respectively, temperature control part divides with heater members and joins, to control its temperature, above-mentioned these parts all are assemblied in the support, constitute a hot melt fusion splicing devices.Though this fusion splicing devices is leveraged to the present always.But exist following shortcoming inevitably, Here it is, because heater members adopts nickel filament heat-generating pipe made of copper, heat-conducting plate is formed and the nickel filament heat-generating pipe is placed in it by the aluminium alloy casting, the heat-generating pipe heating also conducts to heat-conducting plate, the temperature control part branch is made of semiconductor devices, after heat-generating pipe is heated to uniform temperature, temperature control part divides work, the temperature of control heat-generating pipe rises, after long-time the use, can cause the breakdown and temperature control part of heat-conducting plate divide the semiconductor devices of Yin Qinei be heated aged deterioration, service life is short, repair rate is high; In addition, this device is owing to the existence that temperature control part divides, and the whole device that seems is comparatively complicated.
The purpose of this utility model is the shortcoming that exists at above-mentioned conventional hot melt fusion splicing devices, proposes a kind of temp autocontrolled thermoweld unit.
To achieve these goals, the utility model adopts following technical scheme: this temp autocontrolled thermoweld unit comprises pipe welded joint, accessory welded joint, left and right sides heat-conducting plate, support, this device also further comprises PTC heating ceramic body, PTC heating ceramic body adheres between the heat-conducting plate of the left and right sides, pipe welded joint and accessory welded joint are individually fixed in heat-conducting plate both sides, the left and right sides, support is fixed on the two ends of left and right sides heat-conducting plate, is equipped with the power line that is connected with PTC heating ceramic body in the support.
Because fusion splicing devices of the present utility model has adopted the PTC ceramic heating element as the heater members of heater members as fusion splicing devices, after being raised to certain temperature, the PTC ceramic heating element just keeps constant temperature, therefore do not need with adopting temperature control part to assign to regulate temperature again, simultaneously can not cause the too high breakdown phenomenon of heat-conducting plate Yin Wendu yet, make the structure of whole device greatly simplify yet.
Below in conjunction with drawings and Examples, the utility model is done one explains:
Fig. 1 is a fusion splicing devices theory structure schematic diagram of the present utility model.
Fig. 2 is a fusion splicing devices structural representation of the present utility model.
Fig. 3 is the PTC ceramic heating element structural representation of the utility model fusion splicing devices.
See also Fig. 1 and cooperate Fig. 2, shown in Figure 3, this temp autocontrolled thermoweld unit comprises pipe welded joint 13, accessory welded joint 14, support 15, left and right sides heat-conducting plate 11,12, this device also further comprises PTC heating ceramic body 10, PTC heating ceramic body 10 adheres on left and right sides heat-conducting plate 11, between 12, left and right sides heat-conducting plate 11,12 material adopts metallic copper, pipe welded joint 13 and accessory welded joint 14 are individually fixed in left and right sides heat-conducting plate 11,12 both sides, support 15 is fixed on left and right sides heat-conducting plate 11,12 two ends are equipped with the power line that is connected with PTC heating ceramic body 10 in the support 15.
Described PTC ceramic heating element is shaped as plates, is provided with insulating barrier 18,19 between PTC ceramic heating element and the heat-conducting plate 11,12, and the lateral area 101 of PTC ceramic heating element is greater than 20mm with the ratio of heating temp
2: 1 ℃.That is to say (see figure 3), if will make the temperature of PTC ceramic heating element will reach 300 ℃, so, the lateral area 101 of PTC ceramic heating element is 6000mm
2More than.
Please consult shown in Figure 3ly again, in embodiment of the present utility model, described PTC ceramic heating element adopts six platelets to be spliced.The shape difference of six platelets, but its lateral area value is about equally.
In actual applications, will manage welded joint 13, accessory welded joint 14 respectively alignment tube 20, accessory 21 (see figure 1)s heat, and thermofusion device of the present utility model from manage 20 and accessory 21 between extract out, make the butt joint of pipe 20 and accessory 21 hot melts.
