The problems that scale produced between a plunger and a shell of an existing thermostatic valve element made of copper accelerates corrosion of the plunger and the shell, and the overall service life is affected are solved. The novel constant-temperature valve element capable of reducing water scale and long in service life comprises an outer shell, a plunger, a cold water inlet and a hot water inlet, the outer shell and the plunger are both made of copper materials, a plastic inner sleeve for separating the outer shell from the plunger is arranged in the outer shell in a sleeved mode, and the plastic inner sleeve is provided with a cold water through opening and a hot water through opening which are communicated with the cold water inlet and the hot water inlet respectively. Cold water flows into the plunger through the cold water inlet and the cold water through hole, and hot water enters the plastic inner sleeve through the hot water inlet and the hot water through hole and is mixed with the cold water to form cold and hot mixed water. The utility model has the advantages that the scale is reduced, the mutual corrosion and adhesion of the copper plunger and the copper shell are avoided, and the overall service life is prolonged.

Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and relates to a thermostatic valve core, and particularly to a novel thermostatic valve core with scale reduction and long service life. Background Technology

[0002] The outer shell and plunger of existing thermostatic valve cores are usually made of copper. However, after long-term operation, scale easily forms between the plunger and the outer shell. The formation of scale accelerates the corrosion between the two copper parts, causing them to stick together and affecting the overall service life. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel thermostatic valve core with a long service life that reduces scale formation and prevents the copper plunger and copper shell from corroding and sticking together.

[0004] The purpose of this utility model can be achieved through the following technical solution: A novel thermostatic valve core with scale reduction and long service life, comprising a shell, a plunger, a cold water inlet and a hot water inlet, wherein the shell and the plunger are both made of copper. The feature is that a plastic inner sleeve is provided inside the shell to separate the shell and the plunger. The plastic inner sleeve has a cold water inlet and a hot water inlet that are respectively connected to the cold and hot water inlets. Cold water flows into the plunger through the cold water inlet and the cold water inlet, and hot water enters the plastic inner sleeve through the hot water inlet and the hot water inlet and mixes with the cold water to form a hot and cold mixed water.

[0005] In the aforementioned novel thermostatic valve core with descaling and long service life, sealing rings are provided between the plastic inner sleeve and the outer shell, as well as between the plastic inner sleeve and the plunger.

[0006] In the aforementioned novel thermostatic valve core with reduced scale and long service life, the plastic inner sleeve is assembled into the outer shell from top to bottom.

[0007] Compared with existing technologies, this new type of thermostatic valve core with reduced scale formation and extended service life has the advantages of reducing scale formation and preventing corrosion and adhesion between the copper plunger and the copper shell, thereby improving the overall service life.

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, this new type of thermostatic valve core with low scale buildup and long service life includes a housing 1, a plunger 2, a cold inlet 3, and a hot inlet 4. Both the housing 1 and the plunger 2 are made of copper. A plastic inner sleeve 5 separates the housing 1 and the plunger 2. The plastic inner sleeve 5 has a cold water inlet 6 and a hot water inlet 7 that are respectively connected to the cold and hot inlets 4. Cold water flows into the plunger 2 through the cold water inlet 3 and the cold water inlet 6, while hot water enters the plastic inner sleeve 5 through the hot water inlet 4 and the hot water inlet 7 and mixes with the cold water to form a hot and cold mixed water. The plastic inner sleeve 5 separates the copper housing 1 and the copper plunger 2, reducing scale buildup between the plunger 2 and the housing 1, which are made of the same material. At the same time, the combination of plastic and copper materials prevents corrosion between the two.

[0013] Preferably, a sealing ring 8 is provided between the plastic inner sleeve 5 and the outer shell 1, and between the plastic inner sleeve 5 and the plunger 2.

[0014] Preferably, the plastic inner sleeve 5 is assembled into the outer shell 1 from top to bottom.

[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as outer shell 1, plunger 2, cold inlet 3, hot inlet 4, plastic inner sleeve 5, cold outlet 6, hot outlet 7, and sealing ring 8, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
