Definitions
- the invention relates to a water pipe and its application in a heat transfer meter, in particular to a polyamide composite hot water pipe and its application in a heat meter.
- a heat meter is a meter that measures the heat consumption of a heating radiator.
- the water pipes in the heat meter (the upper and the return pipes connected to the ends of the heat meter) generally use copper pipes.
- the defects of the copper tube are high in cost; the second is high heat loss; the third is that copper ions are easily precipitated in a high temperature environment, and adhere to the inner wall of the tube to cause scaling and affect water delivery.
- an object of the present invention is to provide a polyamide composite hot water pipe and its use in a heat meter.
- the object of the present invention is achieved as follows:
- the polyamide composite hot water pipe is mainly made of PA66 (Chinese name is polyamide 66), specifically, the polyamide composite hot water pipe PPS is 67-73% by weight of PA66. After mixing with the remaining amount of PPS (Chinese name is polyphenylene sulfide), it is die-cast (or injection molded).
- the die casting (or injection molding) process is a general die casting (or injection molding) process.
- Polyamide composite hot water pipes are very suitable as water pipes for conveying hot water, such as heating pipes and drinking pipes, and can also replace copper pipes in heat meters.
- the positive effect of the invention is that it concentrates the advantages of the two materials PA66 and PPS, and has the characteristics of high strength, high temperature resistance, no pollution, no scale formation and low heat loss. Suitable as a hot water pipe in the heat meter.
- the polyamide composite hot water pipe is made of PA66 as the main material. After mixing 70% of PA66 and 30% of PPS, it is die-cast (or injection molded). The die casting process is a general die casting (or injection molding) process. Polyamide composite hot water pipe Replaces the copper pipe in the heat meter.
- the polyamide composite hot water pipe is made of PA66. It is a mixture of 67% PA66 and 33% PPS.
- the polyamide composite hot water pipe is made of PA66. It is a mixture of 73% PA66 and 27% PPS.

Abstract
本发明提供一种聚酰胺复合热水管及其在热量表中的应用，所要解决的技术问题是：目前热量表里的输水管线一般都采用铜管。铜管的缺陷，一是造价高；二是热损耗高；三是经常在高温环境下容易析出铜离子，附着在管内壁上后易结垢，影响输水。本发明的要点是：它是将67的PA66和余下量的PPS混合后，经压铸成型。本发明的积极效果是：它坐冷板凳中了PA66和PPS这两种材料的优点，具有强度高、耐高温、无污染、无结垢和热损耗低的特点，非常适合取代热量表中的铜管。
Description
聚酰胺复合热水管及其在热量表中的应用 技术领域
本发明涉及一种输水管及其在输热量表中的应用， 具体说是聚酰胺复合热水管及其 在热量表中的应用。
背景技术
热量表是计量暖气散热器消耗热量的一种仪表。 目前这种热量表里的输水管（接在热 量表两端的上水管和回水管）一般都采用铜管。铜管的缺陷，一是造价高；二是热损耗高; 三是经常在高温环境下容易析出铜离子， 附着在管内壁上后易结垢， 影响输水。
发明内容
为解决上述技术问题， 本发明的目的是提供一种聚酰胺复合热水管及其在热量表中 的应用。
本发明的目的是这样实现的： 聚酰胺复合热水管以 PA66 (中文名称为聚酰胺 66 ) 为主要材料， 具体是聚酰胺复合热水管 PPS是将 67-73% (重量百分比）的 PA66和余下量 的 PPS (中文名称为聚苯硫醚） 混合后， 经压铸 （或注塑） 成型。 所说的压铸 （或注塑） 工艺为通用的压铸 （或注塑） 工艺。 聚酰胺复合热水管非常适合作为输送热水的输水管， 如暖气管、 饮水管， 也可以取代热量表里的铜管。
与现有的铜管相比，本发明的积极效果是：它集中了 PA66和 PPS这两种材料的优点， 具有强度高、耐高温、无污染、无结垢和热损耗低的特点， 非常适合作为热量表中的输热 水管。
具体实施方式
聚酰胺复合热水管以 PA66为主要材料， 是将 70%的 PA66和 30%的 PPS混合后， 经压 铸 （或注塑） 成型。 所说的压铸工艺为通用的压铸 （或注塑） 工艺。 聚酰胺复合热水管 取代热量表中的铜管。
聚酰胺复合热水管以 PA66为主要材料， 是将 67%的 PA66和 33%的 PPS混合后， 经压 铸成型。
聚酰胺复合热水管以 PA66为主要材料， 是将 73%的 PA66和 27%的 PPS混合后， 经压 铸成型。
