This utility model solves its technical problem and be the technical scheme is that a kind of water heater drain valve, including drainage valve switch assembly, described drainage valve switch assembly includes valve body, ball valve switch, ball valve swing handle, magnesium rod fixed support, sealing ring, magnesium rod, described drainage valve switch assembly is arranged on inner bag water pipe head, described inner bag water pipe head is from inner bag discharge outlet outwardly, described valve body includes top nut, valve pocket, water side, described water side is connected to drain pipe by drain pipe jump ring, the built-in magnesium rod fixed support of top nut of described valve body, the outside wall portions of described ball valve swing handle arranges seal groove, O is set in seal groove.
It is arranged below hexagonal socket nut, thus ball valve switch is arranged on valve inner at described ball valve switch.
Described drain pipe is plastic tube, is provided with the flexible pipeline section of spiral type on the plastic tube.
The outside of described ball valve swing handle connects handle.
Described ball valve swing handle is threaded hole, and described handle includes driver chuck and pulls out handle, the centrally disposed screw hole of described driver chuck, and described driver chuck edge is arranged to the limited ring dais of restriction rotatable handle scope.
The described handle that pulls out includes inner chamber and enclosing cover, arranges compartmentation strip and positioning strip at inner chamber, and the inner side of enclosing cover arranges mounting cylinder, in described mounting cylinder intercalation space between compartmentation strip and positioning strip.
A kind of water heater, including above-mentioned any hot hydrophone drain valve.
Compared with prior art, the beneficial effects of the utility model are:
Drainage valve switch modular construction of the present utility model is simple, valve body structure, is combined as a whole the water side of the top nut of connection inner bag water pipe head, connection drain pipe, connects plastic drain-pipe by jump ring, and part is few, easy for installation.
Water heater magnesium rod mounting structure is directly connected with drain valve, the door frame that the fixing seat design of magnesium rod is simply generous, it is achieved magnesium rod does not affect blowdown stream flux while installing, scientific and reasonable for structure.
Drain valve handle advantages of simple of the present utility model, the stroke limit scientific structure design of valve, practical.

Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish.The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " front and back ", " on ", D score, "left", "right", " vertically ", " level ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
In description of the present utility model, it is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should make broad understanding, for instance, it is possible to it is fixing connection.Can also be removably connect, or connect integratedly;Can be mechanically connected, it is also possible to be electrical connection;Can be joined directly together, it is also possible to be indirectly connected to by intermediary, it is possible to be the connection of two element internals.For the ordinary skill in the art, it is possible to concrete condition understands above-mentioned term at concrete meaning of the present utility model.
As shown in figures 1 to 6, water heater drain valve of the present utility model, including drainage valve switch assembly 1, described drainage valve switch assembly includes valve body 2, ball valve switch 3, ball valve swing handle 4, magnesium rod fixed support 6, sealing ring 8, magnesium rod 10, described drainage valve switch assembly is arranged on inner bag water pipe head 12, described inner bag water pipe head is from the discharge outlet of inner bag 11 outwardly, described valve body includes top nut 21, valve pocket, water side 22, described water side is connected to drain pipe 7 by drain pipe jump ring 9, the built-in magnesium rod fixed support 6 of top nut of described valve body, the outside wall portions of described ball valve swing handle arranges seal groove, O 41 is set in seal groove.
It is arranged below hexagonal socket nut 13, thus ball valve switch is arranged on valve inner at described ball valve switch.
Described drain pipe 7 is plastic tube, is provided with the flexible pipeline section 71 of spiral type on the plastic tube.
The outside of described ball valve swing handle connects handle 5.
Described ball valve swing handle is threaded hole, and described handle 5 includes driver chuck 51 and pulls out handle 52, the centrally disposed screw hole 53 of described driver chuck, and described driver chuck edge is arranged to the limited ring dais 54 of restriction rotatable handle scope.The arc range of limited ring dais 54 is more than 180 degree less than 300 degree, and therefore, handle can the rotation angle range of valve body relatively be between 60 degree to 180 degree, and wherein, optimum control angle is 90 degree.Being provided with the limited block of rectangle on the outer wall of valve body 2 mounting ball valve swing handle, after handle is installed, limited block extend in the rotary stopper space formed by limited ring dais, makes ball valve swing handle can rotate 0-90 degree in valve body.After handle is installed, bolts through bolt holes 53, and be fixed tightly on ball valve swing handle, make handle and ball valve swing handle link together.
The described handle 52 that pulls out includes inner chamber 56 and enclosing cover (not shown), arranges compartmentation strip 57 and positioning strip 58 at inner chamber, and the inner side of enclosing cover arranges mounting cylinder, in described mounting cylinder intercalation space between compartmentation strip and positioning strip.
This utility model also provides for a kind of water heater comprising above-mentioned water heater drain valve.
