Phenomenon, so that gas-heating water heater performance is stablized, channeling water phenomenon is less；Meanwhile the heat that the unit time generates is less, reduces
The probability of large deformation occurs because temperature is excessively high for sealing ring, enhances reliability.
Further, it is axial high to be located at cross section and scarf at scarf axial height 1/3 for the position of the line contact
It spends at 1/2 between cross section.Defining for line contact position keeps well contacting between sealing ring and runner end face, enhances
The reliability of sealing.
The utility model additionally provides a kind of water outlet valve of gas heating water heater group, including valve body and driving mechanism, described
Valve body includes the heating outlet passage equipped with first runner end face and the sanitary outfall runner equipped with second flow channel end face；It is special
Sign is, further includes sealing device described in two, and the driving mechanism connects two sealing devices, described in one of them
Sealing device is used to that first runner end face, one of them described sealing device to be blocked or opened under the driving of the driving mechanism
For second flow channel end face to be blocked or opened under the driving of the driving mechanism.
Further, the driving mechanism includes the motor and valve rod of transmission connection, the sealing of two sealing devices
Cover for seat is set on the valve rod.
Further, rotor is arranged on the valve rod, the rotor is set between two sealing devices.
Further, the mounting hole for installed plug is equipped in the seal receptacle, the plug is actively sheathed on institute
It states on valve rod.
Further, the valve rod is equipped with outwardly projecting connector, and the seal receptacle is equipped with O-shaped with valve rod junction
Sealing ring, the plug is between O-ring seal and connector and is equipped with the circular hole cooperated with connector.
Compared with prior art, the utility model has the beneficial effects that the sealing ring of the utility model is embedded in a groove,
It is not susceptible to torsion and rolling under the impact of water flow or in moving back and forth, when bearing impacting with high pressure, there is preferable resist
It deforms, the ability of turnup；The sealing ring of the utility model is compared to O-ring seal, and suffered deformation is smaller, and sealing is more stable, rubs
It is also larger to wipe surplus, there is better seal effect；The sealing ring of the utility model and first runner end face or second flow channel end
Brought into linear contact, it is not easy to there is impurity blocking or the phenomenon that fouling so that gas-heating water heater performance is stablized, channeling water phenomenon compared with
It is few；Meanwhile the heat that the unit time generates is less, reduces the probability that large deformation occurs because temperature is excessively high for sealing ring, enhancing is reliable
