Thank you for your attention and trust! We are committed to offering the most complete safety power services to our customers. Since bimetallic temperature switches are designed based on the principle of thermal expansion and contraction of metals, it's natural to wonder whether other materials could be used to create similar temperature control devices. The answer is yes—pressure-type temperature control switches use the expansion of gas when heated to increase pressure and trigger the switch function. These types of switches are widely used in industrial applications because they provide strong output force and do not require an external power source. They operate entirely on gas, making them suitable for environments requiring intrinsic safety. However, due to their larger size, they are not typically used in small household appliances. Instead, they are commonly found in refrigerators and air conditioners. A typical refrigerator uses a pressure-temperature switch to maintain a stable internal temperature. Let’s take a closer look at how this device works. The temperature adjustment knob and cam set the desired average temperature inside the fridge. The warm pack contains "wet saturated steam," which exists in both gaseous and liquid states, usually made from refrigerants like methane or freon due to their low boiling points and ease of vaporization. This steam expands when heated, increasing pressure. The capillary tube connects the warm pack to a bellows, which is made from a highly elastic material. The electrical contact at one end of the starting lever remains open until the temperature rises enough to cause the steam to expand. This pressure is transmitted through the capillary, causing the bellows to inflate. As a result, the lever is pushed against the tension of a spring, rotating counterclockwise. When the temperature reaches a certain threshold, the contact closes, activating the refrigerator compressor to begin cooling. As the temperature drops, the steam contracts, reducing pressure and breaking the contact, which stops the cooling process. This cycle continues, maintaining a consistent temperature within a specific range and helping to save energy. Although this method isn't as precise as modern frequency conversion technology used in high-end refrigerators and air conditioners, its simplicity, reliability, and low cost have kept it popular in many traditional models.

Anti Slip Flooring Roll

The corridor area is a large flow of people in the wet market and the ground is vulnerable to wear and tear, so it is particularly important to choose a suitable pvc floor mat. This hollow design of the hollow Non Slip Mats is very suitable for the corridor area of the wet market. The following is a brief introduction to the hollow Anti Slip Pvc Floor Mat. The first is its anti-slip design: the hollow anti-slip mat uses a special surface texture and material, which has excellent anti-slip performance. This design effectively prevents pedestrians from slipping in the corridor area and improves the safety of walking. Moreover, it is breathable: the hollow design of the floor mat allows air to circulate freely, helps to keep the ground dry, and reduces the growth of mold and bacteria, which is conducive to maintaining the cleanliness of the corridor area. Finally, its wear resistance, hollow non-slip mat made of wear-resistant materials, can withstand high intensity flow of people and friction, extend the service life, reduce ground wear.
