Goal of the invention In view of the foregoing of the present utility model is to provide a kind of water nozzle that can close automatically when tap water cut-off, so that conserve water, prevent accident such as flood.
In order to realize that above-mentioned purpose the utility model provides a kind of self-closed water tap.This water nozzle by housing, operating stem, be located at water blocking valve used composition the in the housing, it is characterized in that water nozzle water intake and water blocking valve used between be provided with cursory, feeler lever, sucker and sucker and water blocking valve used between compressed spring, and an end of feeler lever is fixed in the top at sucker edge, and the feeler lever supporting is cursory.Further described below in conjunction with accompanying drawing.
The general type of the self-closed water tap that accompanying drawing 1 provides for the utility model, the working state among the figure be the automatic closed condition of water nozzle when pipeline is cut off the water under artificial breakdown;
Accompanying drawing 2 is the artificial breakdown state of self-closed water tap when pipeline is full of water;
Accompanying drawing 3 is the artificial closed condition of self-closed water tap when pipeline is full of water.
Shown in accompanying drawing 1, the self-closed water tap housing is made up of pedestal (1) and shell (9), and it is fixing to be threaded with shackle (5) between pedestal and the shell, and pedestal is provided with water intake, and shell is provided with water outlet.In order to prevent dew, between pedestal and shell, be lined with seal ring (6), between valve seat (8) and shell, also be lined with seal ring (21).Between the water intake of water nozzle and water outlet, be provided with water blocking valve used (7) and valve seat (8), and be rubber ring (22) with the water blocking valve used valve seat that contacts one side.Water blocking valve used shaft core position is by the decision of shackle guiding.Water intake and water blocking valve used between be provided with cursory (2), feeler lever (4), sucker (3), and sucker and water blocking valve used between be provided with compressed spring (23).One end of feeler lever is fixed in the top at sucker edge, and the feeler lever supporting is cursory.Contact surface sucker and water blocking valve used should be smooth, and the material of sucker preferably selects for use rubber to make.One end of sucker is fixed on the shackle.Cursory shape, size will help the Channel Group of water, and its material can select for use glass, aluminium, nylon to add metalwork etc.Annular shape shown in the accompanying drawing 1 is cursory for to make with glass.Cursoryly should satisfy following two conditions: weight cursory when the water intake of water nozzle is anhydrous is enough to make the edge of sucker to be raised by feeler lever, thereby destroys the air-proof condition of sucker, impel sucker and water blocking valve used under the effect of spring force separately; Its two for the supporting force of feeler lever when the water intake of water nozzle is full of water and cursory buoyancy with joint efforts greater than cursory gravity own.Hence one can see that, water blocking valve usedly when pipeline is cut off the water under artificial breakdown state can realize closing automatically water.
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the operating stem of water nozzle (16) is located at an end of shell and fixes its shaft core position by end cap (12).Be provided with the waterproof membrane made from soft material (11) between water blocking valve used and operating stem, waterproof membrane is fixing with shell by end cap, and between barrier film and end cap for preventing that diaphragm wear can be provided with steel pad (19).Barrier film and water blocking valve used between be provided with the tower spring abutment (20) that compressed tower spring (10) withstands, the bottom of tower spring abutment is enclosed within on the water blockoff valve rod, and the water blockoff valve rod that is positioned in the tower spring abutment is provided with jump ring (17).If the purpose of jump ring is to hold water blocking valve used (having under the situation of water) when sucker, and operating stem is when closing direction moves, and the tower spring abutment makes the tower spring abutment by means of the thrust of tower spring bottom is blocked by jump ring and also moved to the movement direction of operating stem water blocking valve used.The elastic force of tower spring (10) is greater than the plasticity elastic force of sucker itself, and the elastic force of spring (23) be less than sucker under air-proof condition sucker and water blocking valve used between ultimate tension.Because the central authorities of waterproof membrane often are operated bar, tower spring abutment and water blocking valve used extruding, thus the central authorities of barrier film can be by rigidity big or hard material make.As shown in accompanying drawing 1, the central authorities of barrier film get final product with common rivet (14) rivet clasp.The utility model when opening artificially in order to control the flow of water, end at operating stem is provided with pin (18), pin closely contacts with the inwall of end cap (12) when operating stem rotates to an angle, and with the contacted end cap inwall of pin be inclined-plane or helicoid.Water nozzle is when opening like this, pin by and the end cap inwall between frictional force water management at certain flow.For the ease of using operating stem, on operating stem, be provided with button (13), this button is fixing with operating stem by nut (15).
When the utility model was installed in water supply pipe according to above-mentioned structure, cursory upper and lower displacement direction should be vertical with substantially horizontal.Self-closed water tap provided by the utility model is when pipeline is cut off the water, and sucker separates all the time with water blocking valve used, and the real time operation bar is in the water blocking valve used valve seat of blocking all the time of opening state; When pipeline has water, sucker with water blocking valve used hold mutually after, no matter operating stem is in and opens or the closed condition sucker does not separate all the time with water blocking valve used, and this moment is cursory inoperative.When pipeline is cut off the water suddenly under the artificial breakdown state, because cursory gravity destroys the air-proof condition of sucker through feeler lever, make the water blocking valve used valve seat of blocking, thereby water nozzle is closed purpose when realizing that pipeline comes water again.Sucker still separates with water blocking valve used when after pipeline stopped water water being arranged, and will open this moment and could realize after water nozzle holds water blocking valve used and sucker by operating stem earlier.
Self-closed water tap provided by the utility model, except having above-mentioned when pipeline is cut off the water, realizing the characteristics of autoshutdown, also have simple in structure, be easy to processing and manufacturing, the characteristics such as easy to use, and since most of finding be located at water blocking valve used outside, thereby do not need other measures of preventing water still can these parts of dismounting and change when pipeline has water. The utility model has significant social effect for timing central water supply area, thereby can extensively promote the use of.
