Abstract
The utility model relates to a multi-proof tap, comprising a valve seat, a water inlet pipe connecting opening and a water outlet pipe connecting opening which are connected with the valve seat, wherein, the interior of the valve seat is provided with a bulkhead and a valve rod, and is also provided with a valve core and a spring pin. In the using process, when the water supply system cuts off the water, the utility model automatically closes, the water escape is prevented, and the water seepage and the water leakage caused by the damage of the valve core are avoided.
Description
The utility model belongs to the poppet valve technical field.
Existing water nozzle can not be closed automatically with the interruption at water source, forgets and closes if open when water system is anhydrous, can cause the phenomenon of metalling run out when coming water again.In addition, the seepage phenomenon that causes owing to the damage of its spool also happens occasionally, thereby causes the waste of water resources.
The purpose of this utility model is a kind of water nozzle that can close automatically with the interruption at water source of design.
The utility model comprises valve seat and the intake pipe interface and the outlet pipe interface that link to each other with valve seat, be provided with the cavity that links to each other with the outlet pipe interface with the intake pipe interface in the valve seat and the valve rod that plug is stretched out in plug and its upper end is installed, it is characterized in that stem lower portion is provided with groove, the cavity lower end is equipped with the spool that can seal the outlet pipe interface, is connected with spring Xiao that an end can head into groove on the spool.
The utility model in use, when running into the water source and interrupt, spring Xiao promptly ejects groove under the effect of spring, spool is fallen, and realizes closing automatically, thereby can avoid when water system is anhydrous because of forgetting that closing water nozzle causes and metal run out.In addition, the utility model is rational in infrastructure, reliable performance, thereby can prevent infiltration, the water leakage phenomenon that the damage because of spool causes.
Accompanying drawing is the utility model embodiment's a structural representation.
Intake pipe interface (9) and outlet pipe interface (10) that present embodiment has valve seat (3) and links to each other with valve seat (3), be provided with the cavity (8) that is communicated with intake pipe interface (9) and outlet pipe interface (10) in the valve seat (3), and plug (2) and vertical valve rod (5) be installed, cavity (8) is square, plug (2) is stretched out in the upper end of valve rod (5), which is provided with handle (1), the bottom of valve rod (5) is provided with groove (11), and the end of valve rod (5) lower end is taper.The lower end of cavity (8) is equipped with the spool (6) that can seal outlet pipe interface (10), is connected with an end on the spool (6) and can heads into interior spring Xiao (7) of groove (11), and this spring Xiao's (7) the other end can cover intake pipe interface (9).Venting plug (4) is installed on the valve seat (3).
In the using process, when supplying water just often, the pressure of water heads in the groove (11) spring Xiao's (7) a end, thereby makes valve rod (5) drive spool (6) proper functioning.When the water source interrupts and water nozzle when also being in opening state, owing to there is not the pressure at water source, spring Xiao (7) is promptly ejecting from groove (11) under the effect of spring, and spool (6) falls automatically, and realization is closed automatically.Come water again and need open water nozzle once more the time, can earlier valve rod (5) be threaded to closed condition when water system, the venting plug of outwarding winding (4) screws after discharging gas again, and rotary valve rod (5) can be opened water nozzle then.
Claims (4)
1, a kind of Multi-proof tap, comprise valve seat (3) and coupled intake pipe interface (9) and outlet pipe interface (10), be provided with the cavity (8) that is communicated with intake pipe interface (9) and outlet pipe interface (10) in the valve seat (3) and plug (2) be installed and the valve rod (5) of its upper end plug (2) when stretching, the bottom that it is characterized in that valve rod (5) is provided with groove (11), the lower end of cavity (8) is equipped with the spool (6) that can seal outlet pipe interface (10), is connected with an end on the spool (6) and can heads into interior spring Xiao (7) of groove (11).
2, according to the described Multi-proof tap of claim 1, the lower end that it is characterized in that valve rod (5) is taper.
3,, it is characterized in that cavity (8) is for square according to claim 1 or 2 described Multi-proof taps.
4,, it is characterized in that on the valve seat (3) venting plug being installed according to claim 1 or 2 described Multi-proof taps.
