Technical Field

The utility model relates to a bathroom equipment field especially relates to a valve shell structure of thermostatic cartridge that suitability is good.

Background

As a core device for regulating water temperature, the thermostatic valve core is widely applied to a thermostatic water heater and a thermostatic faucet. When the water pressure of hot water or cold water changes suddenly or the temperature of hot water changes suddenly, the thermostatic regulating valve core can automatically balance the water pressure of the cold water and the hot water in a short time, so that the temperature of mixed water can be automatically kept at a set temperature to keep the temperature of outlet water stable.

The tap main part on the market at present is divided into integral type tap main part and split type tap main part two kinds. The integral type tap main part is integrated into one piece, and the integral type tap main part is bulky, and processing is simple relatively, but the product percent of pass is lower. As shown in fig. 3, a water inlet 111 ' and a lower water inlet 112 ' are arranged at intervals on the circumferential wall of the valve casing of the thermostatic valve core matched with the integrated faucet body, a water outlet 121 ' is arranged at the lower end of the valve casing of the thermostatic valve core, and a first sealing ring caulking groove positioned above the upper water inlet 111 ', a second sealing ring caulking groove positioned between the upper water inlet 111 ' and the lower water inlet 112 ' and a third sealing ring caulking groove positioned between the lower water inlet 112 ' and the water outlet 121 ' are arranged on the circumferential wall of the valve casing of the thermostatic valve core, and the third sealing ring caulking groove is arranged close to the lower water inlet 112 '; a first sealing ring 21, a second sealing ring 22 and a third sealing ring 23 are respectively arranged in the first sealing ring caulking groove, the second sealing ring caulking groove and the third sealing ring caulking groove; cold water and hot water enter the integrated faucet body from the same side of the integrated faucet body in parallel and then respectively enter the thermostatic valve core through the upper water inlet 111 ' and the lower water inlet 112 ', and mixed water flows out from the other direction of the integrated faucet body through the water outlet 121 ' of the thermostatic valve core.

As shown in figure 4, the inside of the split type faucet main body can be split and assembled or replaced by an injection molding part, the split type faucet main body is small in size, the casting yield of products is high, and the assembly is more complicated. The thermostatic valve core matched with the split type faucet and the thermostatic valve core matched with the integrated faucet main body are characterized in that a fourth sealing ring caulking groove is arranged between the lower water inlet 112 'and the water outlet 121', the fourth sealing ring caulking groove is arranged close to the water outlet 121 ', a fourth sealing ring 24 is arranged in the fourth sealing ring caulking groove, cold water and hot water respectively enter the thermostatic valve core from two directions of the split type faucet main body and respectively enter the thermostatic valve core through the upper water inlet 111' and the lower water inlet 112 ', and mixed water flows out from the split type faucet main body through the water outlet 121' of the thermostatic valve core and the same direction of the hot water.

According to the structure of above-mentioned leading main part and the difference of the mode of intaking, make the sealing washer caulking groove between lower water inlet and the delivery port on locating the thermostatic cartridge have two kinds of structures, one kind is close to the hot water inlet and sets up, another kind is close to muddy water outlet and sets up, only the structure matching of leading main part and thermostatic cartridge valve casing can realize the installation of thermostatic cartridge in leading main part, need two pairs of moulds to produce the valve casing of two kinds of thermostatic cartridges in production, the range of application that makes thermostatic cartridge has certain restriction, consequently, the commonality of thermostatic cartridge valve casing still treats improvement.

SUMMERY OF THE UTILITY MODEL
