Improved structure of precision ceramic control valve

This creation is related to the improvement of the structure of a precision ceramic control valve, especially a precision ceramic control valve with the function of preventing overheating of the outlet water.

Press, the use of the faucet is mainly to use the valve stem of the precision ceramic control valve through the handle of the faucet to drive the valve stem to open the faucet. The mixing ratio of water can even flow out as hot or cold water alone.

However, the conventional precision ceramic control valve does not have a structure to prevent unregulated hot water from flowing out of the faucet, so that the unregulated hot water may still flow out of the faucet directly, and even the temperature of the water is hot and cold. Danger.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional precision ceramic control valves is actually the goal of the relevant industry’s efforts to research and develop. In view of this, the creator has thought and created the idea, and then used many years of experience. To design, after many discussions and sample tests, and many revisions and improvements, it is the creation of this creation.

The conventional precision ceramic control valve does not have a structure to prevent hot water with unregulated temperature from flowing out of the faucet, so that the hot water with unregulated temperature may still flow out. This is a technical problem to be solved.

This creation provides an improvement in the structure of a precision ceramic control valve. The precision ceramic control valve includes: a valve housing, a valve seat, and a temperature limiting device. The valve housing is provided with a valve stem to control the rotation of the valve housing. The seat is activated, and the rotating seat is used to adjust the valve plate assembly of the valve housing to adjust the mixing ratio of cold water and hot water or the size of the outlet water flow. The valve housing and the valve seat are interlocked, and the valve seat It is composed of an upper seat and a lower seat. Between the upper seat and the lower seat there is a water divider of a temperature limiting device. The temperature limiting device includes a water divider, a cap, a support sleeve, a temperature sensor, and a A water stop sleeve and a spring, wherein: the top surface of the upper seat of the valve seat penetrates a cold water hole, a hot water hole, a cold water circulation hole, a hot water circulation hole and a first temperature adjustment hole, and the bottom surface is opposite to the The positions of the cold water hole, the hot water hole and the hot water circulation hole are divided into a first chamber and a second chamber. At least one cold water outlet hole and a mixing outlet hole, the cold water inlet hole and the hot water inlet hole are respectively used to connect the cold and hot water sources, the top surface of the lower seat is formed with a higher than the water divider The convex part allows the cold water inlet hole and the hot water inlet hole to be arranged on the convex part and then penetrate the bottom surface. The water divider is provided with a connection with the first chamber and the convex part For penetrating parts with the same shape, when the water divider is installed with the temperature limiting device provided by its internal control greenhouse, the first chamber and the second chamber are respectively aligned with the penetrating part The upper seat is covered on the top surface of the water divider, and then the combination of the water divider and the upper seat is sleeved on the top surface of the lower seat to make The cold water inlet hole and the hot water inlet hole of the lower seat can respectively form conduction with the cold water hole and the hot water hole of the upper seat. The cap of the temperature limiting device is a closed cover with an opening facing downwards. The peripheral ring is provided with a plurality of hot water passage holes penetrating the cap. The inner edge of the support sleeve of the temperature limiting device is provided with a number of protrusions The claws, so that every two adjacent claws can become a water outlet channel, the support sleeve is combined with the mixed water outlet hole of the lower seat, so as to use the protruding claws of the support sleeve to provide the feeling The thermostat is placed on the support, and the support sleeve is provided with a ring groove on the outer periphery, and the ring groove is sleeved with a water stop ring. The installation of the water stop ring enables the gap between the support sleeve and the mixing water outlet to be sealed. An ejector rod is set in the opening at one end of the temperature sensor, and the inside is filled with a chemical substance that can undergo thermal expansion and contraction effects due to changes in ambient temperature. The thermal expansion of the chemical substance enables the ejector rod to move from The opening is greatly pushed and squeezed out by the chemical substance, and the chemical substance can be restored to its original volume after cooling. The water-stop jacket has a tubular body and a cover with a top surface penetrating through it and the opening facing downwards. , The casing and the tubular body are internally and externally sheathed and then combined with a bottom edge, and the bottom edge is provided with a plurality of water-passing holes at intervals, and the casing provides the temperature sensor with the top rod The one side end section of the piercing, will enable the water stop cover to be appropriately set on the temperature sensor, the spring is supported between the cap and the water stop cover, so as to be in the top rod In the normal state of retracting, push the water-stop jacket so that the tubular body of the water-stop jacket can go down to avoid the hot water passage hole of the cap, so as not to shield the hot water passage hole. Using the support of the temperature sensor to raise the water stop jacket can also prevent the cold water passage hole of the water divider from being blocked by the tubular body of the water stop jacket, so that the cold water passage hole can always be blocked. It is connected with the water outlet channel of the support sleeve; with the above structure, the precision ceramic control valve is installed in the valve chamber of the faucet, and the valve stem is used to connect the handle.
