Stainless steel sensor faucet and production method thereof

Abstract

A stainless steel sensor faucet comprises a water outlet pipe and a base, wherein the water outlet pipe is in the shape of a bent pipe, the base is internally provided with a water communicating cavity and a mounting cavity used for arranging a sensor, the faucet is made of stainless steel material, and the water outlet pipe and the base have a split-type structure and are welded together. The stainless steel sensor faucet has the beneficial effects that: the sensor faucet is made of stainless steel material, not only has low production cost, but also is sanitary and environment-friendly, and is beneficial to the physical and psychological health of the populace. In addition, the stainless steel sensor faucet has simple casting technique, greatly saves labor force, improves the yield, reduces production cost, and is suitable for generalization.

Description

technical field [0001] The invention relates to a faucet, in particular to a stainless steel induction faucet and a production method thereof. Background technique [0002] At present, the existing induction faucets in my country are all made of zinc alloy and copper, and are made of sand casting with the original technology. These two materials are heavy metals, which will cause secondary pollution to water quality, and long-term use is harmful to human health. For the sake of human health, the water quality is not subject to secondary pollution, and the material needs to be replaced with stainless steel. At present, many enterprises have invested a lot of financial resources and energy, but they have not been able to achieve their wishes. Zinc-copper alloy is used as the material. Because of the low melting point of this material, it is suitable for sand casting. A clay core can be used in the cavity. After casting, because of the low melting temperature of the material,...

Problems solved by technology

It is more difficult to produce induction faucets with stainless steel, and the difficulty is as follows: due to the high melting point of stainless steel, the temperature of molten steel can only be cast at 1700 ° C, and the requirements for refractory materials for the mold shell are very high. Usually, zircon powder, zircon sand, and silica sol are used. It can be made into shell paint, which can only be made in 4-5 layers, so the process is complicated and the operation is troublesome

In addition, due to the special structure of the induction faucet (the outlet pipe is long and curved, and there are two cavities in the base, which are used to place the sensor and pass the water respectively), the overall faucet is long and can only be used The water inlet is used as the hole where the paint loose sand enters. When the shell is made, the paint loose sand cannot enter freely, so the viscosity of the paint has to be diluted, and fine sand is used to make the shell under difficult operation.

The quality of the shells produced in this way is not good. After pouring molten steel at a high-strength temperature of 1700°C, most of them will leak molten steel in the cavity. A few of them are poured, and because of high-temperature sintering, they will also be scrapped because the waste sand inside the faucet cannot be cleaned.
