Description
Technical field
The utility model relates to a kind of valve that is used for water heater.
Background technique
Usually the water inlet Placement of water heater is: the tap water water inlet is distolateral to be provided with an inlet valve, by entering the water tank in the water heater behind pressure-relief valve of flexible pipe connection, discharge behind the inlet valve through entering shower nozzle (gondola water faucet) behind the outlet valve of heated hot water by water tank.There is ponding in water heater after using in the water tank, when temperature was reduced to subzero, ponding can freeze, and caused the water tank bursting by freezing.Therefore, existing antifreeze way is: close inlet valve, pull down pressure-relief valve, open the outlet valve or the shower nozzle of water tank, the ponding in the emptying water tank.But because complicated operation, and the user often do not know the water heater inner structure, do not know or dare not pull down pressure-relief valve, causes the ponding in the water tank not to be discharged from, and causes water tank by the loss of bursting by freezing.
Summary of the invention
The purpose of this utility model provides a kind of water heater frost valve easy to operate, simple in structure and that freely switch easily between water inlet and hull-borne.
Technical solution of the present utility model is: a kind of water heater frost valve, and it comprises valve body and valve ball, level is provided with water intake along clockwise direction in the described valve body, drain opening, the 3rd exports and water outlet, and the 3rd outlet port is provided with plug; Be provided with the first passage, second channel and the third channel that are the T type in the described valve ball, under the water inlet state, first passage communicates with water intake, second channel communicates with the 3rd outlet, third channel communicates with water outlet, and under hull-borne, first passage communicates with water outlet, second channel communicates with drain opening, and third channel communicates with the 3rd outlet.
Valve inner is provided with four outlets that are interconnected of arranged clockwise, but the 3rd outlet port is provided with plug, so it can be the T type with the outlet of extraneous UNICOM, and is provided with three passages that also are the T type in the valve ball, under the water inlet state, water intake communicates with first passage, and third channel communicates with water outlet, and this moment, second channel communicated with the 3rd outlet, drain opening is sealed by valve ball, water inlet can free enter water outlet by valve ball, and can not discharge by drain opening, and water heater can normally use; When the rotation valve ball entered hull-borne, first passage communicated with water outlet, and second channel communicates with drain opening, this moment, third channel communicated with the 3rd outlet, water intake is sealed by valve ball, and the water in the water-heater water tank enters valve ball by water outlet, discharges from drain opening.Switching between water inlet state and the hull-borne only needs valve ball revolved and turn 90 degrees just and can realize, and is easy and simple to handle, whole frost valve simple in structure, and working stability is convenient to safeguard.
Described first passage is identical with the third channel internal diameter, and the second channel internal diameter is less than the first passage internal diameter.Have enough flows when guaranteeing water inlet.
The utility model has the advantages that: overall volume is little, and is simple in structure, easy to operate, and valve ball revolves and turn 90 degrees the switching that just can realize intaking with draining, and working stability is convenient to safeguard.

Embodiment
Embodiment:
Consult Fig. 1-10, a kind of water heater frost valve, it comprises valve body 1 and valve ball 2, valve body 1 has 5 ports, one of them port is vertically set on the top, and inside is provided with valve rod 4, and four ports are horizontally disposed with along clockwise direction in addition, be respectively water intake 5, drain opening 6, the 3rd outlet 7 and water outlet 8, and the 3rd outlet 7 places are provided with plug 13; Consult Fig. 3 and 6, four horizontal port places in the valve body 1 are provided with seal ring 14,15,16 and 17 respectively.
Consult Fig. 7-10, valve ball 2 is provided with in being by the valve ball center and is the solid sphere of first passage 9, second channel 10 and the third channel 11 of T type, and valve ball 2 tops are provided with breach 12, are connected with valve rod 4 bottoms, and valve body 1 is extended at valve rod 4 tops, and connects handle 3.
During use, the water intake 5 of valve body 1 is connected on the tap water pipe line, water outlet 8 is connected in the water tank import of water heater, and drain opening 6 connects a draining plastics sebific duct, is connected to floor drain etc. and locates.Consult Fig. 2-3, under the water inlet state, first passage 9 communicates with water intake 5, and second channel 10 communicates with the 3rd outlet 7, and third channel 11 communicates with water outlet 8; This moment, tap water was by water intake 5 flow through first passage and third channel 11, entered the water heater from water outlet 8, and water heater can normally use.
