Description
The utility model relates to the special-purpose anti-freeze water inlet of a kind of water heater exhaust-valve.
Flue Gas Water Heater, forced-ventilated water heater and balanced type water heater are outdoor owing to all having a flue to lead to, in the winter of north cold, when water heater did not use, cold air can enter in the water heater along flue, will freeze if there is water in the water heater, the splashing to expand of ice suffers damage water heater.Existing a kind of draining safety valve can be got rid of the water that has in the water heater, but after using up, again it be loaded onto at every turn, during draining, again it is pulled down, and uses very inconvenient.
The purpose of this utility model provides a kind of easy to use, when not using water heater, and the special-purpose anti-freeze water inlet of the water heater exhaust-valve that can automatically the water in the water heater be discharged.
In order to achieve the above object, the utility model is achieved in that and is provided with water inlet and delivery port that on valve body water inlet and delivery port are communicated with by water stream channel; On valve body, also be provided with handle; In valve body, be provided with the spool that when handle rotates, water stream channel can be opened or blocked that is connected with handle; It is characterized in that: spool is a ball core, it is rotatable in valve body, central authorities at the ball core have a through hole, when boiling water, the ball core forwards through hole to and communicates with water stream channel under the drive of handle, work as Guan Shuishi, the ball core forwards through hole to and does not communicate with water stream channel, and water inlet is blocked in a side of ball core at this moment; Opposite side at the ball core has an inlet opening, and this inlet opening communicates with through hole, works as Guan Shuishi, and this inlet opening communicates with delivery port; Also be provided with an exhalant canal on valve body, work as Guan Shuishi, this exhalant canal is communicated with through hole.The diameter of through hole is identical with the diameter of water stream channel, and the diameter of ball core is compared greater than 1.5 times with the diameter of water stream channel.Inlet opening and through hole on the spool are orthogonal.Around the ball core, be provided with elastic sealing element.Seal be one be located at the ball core up and down the upper-lower seal pad and the seal washer that is located at the side form.Be provided with a clamping screw in the housing side, screw rod matches with the seal washer that is located at the side.
The utility model compared with prior art has following advantage:
1, simple to operate, easy to use;
2, simple in structure, low price.
Structural representation when Fig. 1 is the utility model boiling water;
Structural representation when Fig. 2 closes water and draining for the utility model.
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, 2, be provided with water inlet 7-1 and delivery port 7-4 on valve body 7, water inlet 7-1 and delivery port 7-4 are communicated with by water stream channel 7-3; On valve body 7, also be provided with handle 1; In valve body 7, be provided with the ball core 6 that is connected with handle 1, ball core 6 can turn in valve body 7 under the drive of handle, the diameter of ball core 6 is twices of water stream channel 7-3 diameter, central authorities at ball core 6 have a through hole 6-1, and the diameter of this through hole 6-1 is identical with the diameter of water stream channel 7-3, when boiling water, ball core 6 forwards through hole 6-1 to and communicates with water stream channel 7-3, work as Guan Shuishi, ball core 6 forwards through hole 6-1 to and does not communicate with water stream channel 7-3, and this moment, water inlet 7-1 was blocked in ball core 6 one sides; Opposite side at ball core 6 has an inlet opening 6-2, and inlet opening 6-2 and through hole 6-1 are perpendicular, and this inlet opening 6-2 communicates with through hole 6-1, works as Guan Shuishi, and this inlet opening 6-2 communicates with delivery port 7-4; Also be provided with an exhalant canal 7-2 on valve body 7, exhalant canal 7-2 and water stream channel 7-3 are perpendicular, work as Guan Shuishi, and this exhalant canal 7-2 is communicated with through hole 6-1.Around ball core 6, be provided with elastic sealing element, it be one be located at the ball core 6 about upper-lower seal pad 3 and be located at seal washer 5 compositions of side; Be provided with a clamping screw 5 in valve body 7 sides, screw rod 5 matches with the seal washer 4 that is located at the side, adjusts the position of ball core 6.When boiling water, 1 inverse time of handle is rotated 90 °, through hole 6-1 communicates with water stream channel 7-3, water smoothly from water inlet 7-1 to delivery port 7-4; Work as Guan Shuishi, clockwise rotate 90 ° on handle, 7-2 is logical mutually with exhalant canal for through hole 6-1,7-1 blocks with water inlet, inlet opening 6-2 is facing to delivery port 7-4, water in the water heater flows to exhalant canal 7-2 from inlet opening 6-2, and can not occur freezing phenomenon owing to do not have water in the water heater even temperature is reduced to subzero this moment yet.
