Detailed description of the invention
Clearly understand for making goal of the invention of the present utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, embodiment of the present utility model is described, it should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
As the liquid-ring type calibration sleeve that Fig. 1 and 2 is plastic pipe, Fig. 1 is liquid-ring type calibration sleeve schematic diagram, and Fig. 2 is A place partial enlarged drawing in Fig. 1.As shown in Figure 1, liquid-ring type shaping cover comprises sleeve pipe 4, mounting flange 3, connector 2 and upper shield 1, and sleeve pipe 4 runs through mounting flange 3 and connector 2, and sleeve pipe 4 is relative with connector 2 fixing by tolerance fit, and sleeve pipe 4 flushes with one end of connector 2; Mounting flange 3 is fixedly connected with sleeve pipe 4, and whole calibration sleeve can be arranged on the input of vacuum tank by mounting flange 3 by liquid-ring type calibration sleeve; Upper shield 1 lid is located at one end of connector 2, and this end is feed end, and is threaded with connector 2, also can use the releasable connection modes such as key connection; The sidewall of connector 2 is provided with blasthole 201, being filled with for cooling water.As shown in Figure 2, there is space 5 with between corresponding connector 2 end face in the lower surface of upper shield 1, both ends of the surface are not fitted.
As shown in Figure 3, Fig. 3 is upper shield schematic diagram.Visible, the corresponding sleeve pipe 4 of upper shield 1 is provided with feed-throughs 103, described feed-throughs 103 the is through upper and lower end face of upper shield, and the truncated cone shape for standing upside down, and lower end section is greater than the internal diameter of sleeve pipe 4.Upper shield 2 side is also provided with external screw thread, Neng Gouhe.Upper shield 1 comprises the round platform 101 being arranged on lower surface, forms ring-shaped cavity 6, as shown in Figure 2 between round platform 101 and connector 2 end face.
As shown in Figure 4, Fig. 4 is the combination schematic diagram of connector and sleeve pipe.Water ring cavity 202 is there is, for cooling the base pipe in this section of sleeve pipe 4 in connector 2.Corresponding water ring cavity 202 position is also symmetrically arranged with two limbers 205, is respectively used to into water and water outlet, ensures the circulation of the cooling water of water ring cavity 202, improves cooling effect.Connector 2 also has three blastholes, 201, three blastholes 201 and is uniformly distributed, for injecting cooling water in ring cavity 6.Connector 2 is also provided with internal thread 204 with the inner surface of upper shield 1 link, and mounting flange 3 link is provided with screwed hole 203.Sleeve pipe 4 is staggeredly equipped with delivery port 401, delivery port 401 is strip.
As shown in Figure 5, Fig. 5 is mounting flange schematic diagram.Mounting flange 3 has installing hole 301 and connecting hole 302.Through installing hole 301, screw, through connecting hole 302, screws in the screwed hole 203 of connector 2 screw on the vacuum box by fixing for mounting flange 3, completes the fixing of mounting flange 3 and connector 2.
In process of production, first liquid-ring type calibration sleeve is arranged on the input of vacuum tank, blasthole 201 and limbers 205 are connected into cooling water pipeline and pass into cooling water.Cooling water is full of in water ring cavity 202 in connector 2; Also be full of cooling water at ring-shaped cavity 6 simultaneously, and flowed out by space 5.Base pipe is tentatively cooled in atmosphere by the mouth mould of extruder and then stretches into liquid-ring type calibration sleeve.Base pipe enters in sleeve pipe through upper shield 1, and base pipe stretches into rear cooling water and forms water ring at space 5 place, and water ring is as the entrance of liquid-ring type calibration sleeve, and first water ring directly contacts with base tube-surface lowers the temperature to base pipe.Base pipe by after water ring, connector 2 is lowered the temperature to base pipe by heat trnasfer.Last base pipe enters sleeve pipe 4, and due to staggered delivery port 401, the shower water outside sleeve pipe 4 forms moisture film in sleeve pipe 4, makes base pipe Cooling and Lubricator, is conducive to tubing steady in a long-term.
There is space between the utility model upper shield end face and connector end face, make after when producing, cooling water injected by blasthole, directly contacted with base pipe by space, formation water ring in gap is that base pipe is lowered the temperature in import department.Upper shield and connector adopt and are threaded, the size in space is there is between adjustable upper shield end face and connector end face, corresponding unlike material and the plastic pipe of different-thickness (PP, PPR, PE etc.) time adopt different gap, because base pipe temperature is higher, softer yielding, different pore size ensures the water yield size of water ring, avoids being damaged tube surfaces greatly by the cooling water flow in space; Adopt this releasable connection that is threaded can so that the replacing of upper shield and cleaning.Be provided with water ring cavity in the utility model connector, in water ring cavity, pass into and discharge the cooling water of circulation by limbers, insert the part of connector for cooling collar.The utility model upper shield lower surface is provided with round platform, forms ring-shaped cavity between round platform and connector end face, and ring-shaped cavity is that the water ring that space is formed provides the cooling water of stable and uniform flow, can also increase the hydraulic pressure of water inlet simultaneously.
Although the embodiment that the utility model discloses as above, the embodiment that its content just adopts for the ease of understanding the technical solution of the utility model, is not intended to limit the utility model.Technical staff in any the utility model art; under the prerequisite not departing from the core technology scheme that the utility model discloses; any amendment and change can be made in the form implemented and details; but the protection domain that the utility model limits, the scope that still must limit with appending claims is as the criterion.
