Abstract
The utility model discloses an improved ball valve used for a water heater, which comprises a three-way valve body with two water inlets and a water outlet, a valve rod, a hand wheel and a spherical valve core. The spherical valve core is fixedly connected at one end of the valve rod, the valve rod with the spherical valve core is fixed in the three-way valve body, the three-way valve body is hermetically exposed at the other end of the valve rod and fixedly connected with the hand wheel, and the spherical valve core is a casing body with a through hole in the direction of the valve rod. The utility model is characterized in that two grooves are arranged in the circumference direction on the external surface of the spherical valve core, the sectional area of one groove is increased, the sectional area of the other groove is not changed, and the other groove is communicated with the through hole. In the practical application, one water inlet is connected with the hot water pipe of the water heater, the other water inlet is connected with the cold water pipe of the water heater, when the two grooves are communicated with the two water inlets, hot water and cold water flow into the water outlet pipe from the circumference surface and the casing body, thus the cold water can not directly impact the hot water pipe to cause the large burning of the water heater to stop to be changed into long open flame. The operation is convenient.
Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of improvement ball valve that is used for water heater.
Background technique
At present, domestic gas-fired water heater has been come into huge numbers of families.The water heater duration and degree of heating one regularly can regulate water temperature by regulating inflow, but such regulating method is received the influence of hydraulic pressure easily, and is too little as flow, then can not light water heater because hydraulic pressure is not enough.Therefore, such adjusting water temperature mode uses very inconvenience, and the mode of available technology adopting ball valve can be alleviated this problem, but can not thoroughly solve, especially when cold water pipe and hot-water line were opened simultaneously, cold water was rushed in the hot-water line easily, causes water heater to be unable to supply sufficient hot water.
The model utility content
The utility model provides a kind of convenient adjusting water temperature in order to solve the deficiency of water heater temperature's regulative mode of the prior art, and is not subjected to the improved ball valve that is used for water heater of influence of hydraulic pressure.
A kind of improved ball valve that is used for water heater, comprise a three way valve that two water intakes and a water outlet are arranged, valve rod, handwheel and spherical valve core, connect firmly spherical valve core on one end of valve rod, the valve rod that has spherical valve core is fixed in the three way valve, the other end of valve rod exposes three way valve hermetically, and connect firmly with handwheel, spherical valve core is a housing that a through hole is arranged on the direction of valve rod, it is characterized in that, on the circumferencial direction on the outer surface of spherical valve core, have two grooves, the sectional area of one of them groove changes from small to big, and another slot cross-section amasss constant and communicates with through hole.
When practical application, hot-water line that fetches from water heater of two water intakes, another connects cold water pipe, when the communicating of two grooves with two water intakes, two kinds of water enters outlet pipe respectively in the circumferential surface of spherical valve core and housing, like this, cold water causes the water heater large-scale combustion to stop with regard to can directly not impacting hot-water line and becomes " ever-burning flame ".Easy to use.
Description of drawings
Fig. 1 is a main sectional view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is done a detailed description:
Referring to Fig. 1, Fig. 2, a kind of improved ball valve that is used for water heater, three way valve 4 comprises on the end of water intake 1,2 and water outlet 3 valve rods 5 and connects firmly spherical valve core 6, spherical valve core 6 is fixed in the three way valve 4, one end of valve rod 5 exposes three way valve 4 hermetically, and connect firmly with the handwheel (not shown), spherical valve core 6 is the housings that a through hole is arranged on the direction of valve rod, on the circumferencial direction on the outer surface of spherical valve core 6, have two grooves 7,8, the sectional area of groove 7 changes from small to big, groove 8 sectional areas are constant, and groove 8 communicates with through hole.
During use, utilize the handwheel rotation valve rod to drive spherical valve core and rotate, the groove 8 that cross-section area is constant is connected with hot-water line, keep hot water flow constant, rotate spherical valve core, because groove 7 cross-section areas are the variations of changing from small to big, can regulate the inflow of cold water, thereby can regulate
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
