Single Fever Shower Mixer Tap is a bathroom equipment that achieves synchronous adjustment of cold and hot water flow and temperature through a single operating lever. It is widely used in home bathrooms, hotels, and public shower rooms. Its core design uses a built-in constant temperature valve core or mechanical mixing structure to accurately mix cold and hot water and output it to the shower head, combining ease of operation, water-saving performance, and safety. Compared to traditional dual handle faucets, the single handle design reduces the risk of misoperation, especially suitable for the elderly, children, and users who pursue an efficient bathing experience.

2、 Core Features

Single handle integrated operation

Data: The stroke range of the operating lever is 60 ° (from the cold end to the hot end), the temperature adjustment accuracy is ± 1.5 ℃, the flow control range is 1.5-12 liters per minute (L/min), and the response time is ≤ 0.8 seconds.

Analysis: Users adjust the water temperature by rotating left and right (from 0 ℃ on the cold end to 50 ℃ on the hot end), and control the flow rate by pulling up and down (closing to maximum). Actual testing shows that within a 60 ° stroke, it is possible to achieve stepless adjustment from ice water to 45 ° C hot water, meeting the need for quick switching. The flow control is achieved through a ceramic valve core, and the opening is linearly related to the flow rate. The minimum flow rate of 1.5L/min is suitable for water-saving mode, and the maximum flow rate of 12L/min can quickly fill the bathtub.

Thermostatic valve core technology (high-end models)

Data: Wax Thermostatic Element is used, with a temperature response time of ≤ 3 seconds, a temperature fluctuation range of ± 2 ℃, a water pressure fluctuation resistance of 0.1-10 bar, and a durability of ≥ 500000 switching cycles.

Analysis: Paraffin components automatically adjust the ratio of hot and cold water through the principle of thermal expansion and contraction. When the cold water supply is interrupted, the valve core can close the hot water channel within 1 second to prevent burns (in accordance with the EU EN1111 safety standard). Actual measurements have shown that under a water pressure fluctuation of 0.5Bar, the temperature fluctuation of the effluent is only ± 1.8 ℃, far lower than the ± 5 ℃ of the mechanical valve core. After 500000 durability tests, the sealing performance of the valve core still reached 98%, with a leakage rate of ≤ 0.05L/min.

Anti scald safety design

Data: The default maximum outlet temperature of the temperature limiting device is 49 ℃ (adjustable to 38 ℃ -55 ℃), and the surface temperature of the anti scalding valve body is ≤ 45 ℃ (after 30 minutes of operation). The child safety lock needs to be pressed and rotated simultaneously to activate the high temperature mode.

Analysis: The temperature limiting device is implemented through mechanical buckles or electronic chips to prevent users from mistakenly adjusting to high temperatures. Actual testing shows that at an ambient temperature of 45 ℃, the temperature of the contact area on the valve body surface is 4 ℃ lower than the water temperature, avoiding the risk of burns. The child safety lock reduces the probability of accidental contact and lowers the risk of accidental operation by 80% by increasing the operating resistance (requiring 2.5N · m torque).

Water conservation and energy efficiency performance

Data: Equipped with a water-saving aerator (flow rate ≤ 9L/min), the water efficiency level meets the national first-class standard (water-saving rate ≥ 30%), and the hot water energy consumption is reduced by 25% (compared to traditional dual handle faucets).

Analysis: The aerator uses air injection technology to improve the fullness of water flow. At a measured flow rate of 9L/min, the water flow covers a diameter of 15cm, and the shower comfort is comparable to the traditional flow rate of 12L/min. By precise mixing of water, the waste of cold water during the preheating stage is reduced, saving about 15 liters of water per shower (calculated based on a 10 minute shower), and the annual water savings can reach 5.5 tons (for a family of three).

Material and Corrosion Resistance

Data: The main material is 59 copper (with a copper content of ≥ 59%), the surface coating thickness is ≥ 8 μ m (nickel layer 5 μ m+chromium layer 3 μ m), the salt spray test has passed for 480 hours (neutral), and the hardness is ≥ 800HV.

Analysis: Copper 59 has passed antibacterial testing (with an Escherichia coli inhibition rate of ≥ 99%), and the coating adhesion meets the ASTM B571 standard. After 1000 friction tests, the steel wool did not peel off. After 480 hours of salt spray testing, the surface corrosion area is ≤ 0.3%, far exceeding the national standard requirement of 240 hours and suitable for high humidity bathroom environments.

3、 Application scenarios

4、 Maintenance Guide

Daily cleaning

Steps:

Wipe the surface scale with a soft cloth every week (acidic cleaning agents are prohibited to avoid corroding the coating).

Disassemble the aerator (counterclockwise rotation) every month and clean the impurities in the filter screen (with a pore size of 0.5mm) with a toothbrush.

Check the flexibility of the operating lever every quarter. If there is any jamming, spray food grade silicone oil for lubrication.

Data: Regular cleaning can reduce the water flow attenuation rate to 5% (after 1 year of use), and the coating glossiness retention rate is ≥ 85%.

Deep maintenance

Cycle: Replace the valve core sealing ring (O-ring) every 2 years, and test the performance of the constant temperature element every 5 years (if the temperature fluctuation is greater than 3 ℃, it needs to be replaced).

Scale removal: Soak the valve body in a 5% citric acid solution for 2 hours every six months to remove internal scale; If the scale is severe, an ultrasonic cleaning machine can be used to treat the valve core (frequency 40kHz, time 10 minutes).

Troubleshooting and Precautions

Unstable water temperature: Check if the cold water pipe is blocked (if the flow rate is less than 1.5L/min, it needs to be unblocked), or if the constant temperature element is malfunctioning (professional tools need to be used for inspection).

Leakage problem: 90% of the leakage is caused by aging of the sealing ring, which can be solved by replacing the O-ring (size Φ 15 × 2.5mm).

Loose operating lever: Tighten the fixing screws (torque 8-10N · m) to avoid excessive force causing the valve body to crack.

Long term disuse: Close the main water valve, drain the accumulated water in the valve body, and prevent frost cracking (antifreeze covers need to be installed in northern regions).
