Problems solved by technology

For example, 97204892.8 discloses that Yishen adopts a shower water temperature control method that uses the joint action of a temperature sensor and a pressure detection sensor, but this method is relatively complicated and is not suitable for the water temperature control of each shower head; 91230691.2 discloses that Yishen uses a metal temperature control spring to control the shower An automatic temperature control device for water temperature, but this device needs to use a special temperature control spring, which has poor stability, high cost and short life
[0005] Thermosensing wax has been widely used in some fields, but there is no technical disclosure in controlling shower water temperature. The main reason is that there is no thermosensing wax material with suitable performance. In addition, the high production cost of thermosensing wax is also an important factor that limits the application of this type of product. reason

Embodiment 1

[0017] Take commercial soap wax with a melting point of 42.5°C and an oil content of 3%, sweat it with 42.0°C as the end point temperature, and take its three waxes (melting point is 40.8°C) as the product.

[0018] Add 5% clay to the above sweat product at 120°C, mix for 0.5 hour, and then filter to obtain the target product. The expansion performance curve of the shower thermostat valve made of this product is as follows: figure 1 shown.

Embodiment 2

[0020] Take the second-line wax paste (oil content is 15m%) with a melting point of 42.2°C, sweat at 43.5°C as the end point temperature, and take its second wax (38.7°C as the melting point) as the product; use the above product as the end point temperature at 42.0°C Sweat, take the second wax (melting point is 35.8°C) as the product; use the above product to sweat with the end temperature of 36.0°C, take the wax (melting point is 36.8°C) as the product.

[0021] Add 3% clay to the product obtained by sweating for three times at 130°C, mix for 1 hour, and then filter to obtain the target product. The expansion performance curve of the shower thermostat valve made of this product is as follows: figure 2 shown.

Abstract

The present invention relates to waxy temperature sensing medium for automatic temperature regulating valve and its preparation process. The destination product is prepared with petroleum wax containing C18-C23 components as material and through once or multiple and refining. The present invention has simple preparation process, low material cost, low refining cost and thus low product cost. The product of the present invention is used in temperature regulating valve for shower bath to reach the effect of autoamtic water temperature regulation and has the features of fast temperature regulation and water saving.

Description

1. Technical field [0001] The invention belongs to the technical field of special waxes, and in particular relates to a wax temperature-sensitive medium for an automatic temperature-regulating valve, specifically a wax-sensitive temperature-sensitive medium for a shower automatic temperature-regulating valve and a preparation method thereof. 2. Background technology [0002] The temperature control valve using wax as the temperature-sensing medium is a self-operated switch. Its principle is to use the volume change of the wax medium during the phase change process to control the opening of the valve so as to achieve the purpose of controlling the flow of the material flow. This wax temperature control valve has dual functions of sensing ambient temperature changes and output action. Because the wax temperature control switch has the advantages of temperature characteristics that do not change significantly with the system pressure, high mechanical strength, good chemical sta...
