Abstract
The utility model relates to a water saving device for the running water, mainly comprising a valve body, a valve handle, a valve body, a through hole, a through hole of the valve handle, a pedal, a spring, etc. The utility model is characterized in that the water saving device for the running water is arranged on one end of the running water pipeline close to a water outlet pipe. When pedaling the pedal, the valve handle downward moves. The through hole of the valve handle and the through hole of the valve body are communicated and the water can flow out. When not required, the valve handle can be sprung up by the function of the spring by only leaving off the feet and the valve handle blocks the pipeline of the water source. The utility model has the advantages of simple structure, easy manufacture, uneasy damage and good water saving effect.
Description
The utility model belongs to a kind of water saving fixtures.
In daily life, the public faucet of public place particularly usually can be seen because water tap damages or forgets closing valve and current are more than.Because China's daily life and industrial water increase year by year, the underground water reserves reduce year by year, and using water wisely is at present more and more paid attention to by people, but go back the better measure of Shang Weiyou at present and install to reduce the particularly water waste of public faucet.
The purpose of this utility model provides a kind of foot-operated water saving fixtures, and this device is installed on the end of conduit pipeline near water outlet, to solve the water tap damage or to forget the water waste problem that causes of closing.
The utility model structure as shown in drawings.Mainly form by valve body (3), gland (4), pedal (6), valve rod (11), spring (13).The diameter 15-20mm that the utility model is achieved in that a valve rod (11) in valve body (3), one section diameter is a bit larger tham two sections at two ends in the middle of the valve rod (11) has a stem through-hole (10) on one section valve rod of centre.Be with a spring (13) in the lower end of valve rod (11), the height of spring (13) is slightly smaller than the length of following one section valve rod, and the external diameter of spring (13) is slightly smaller than the diameter of valve opening (12), is a bit larger tham the diameter of lower end valve rod.One valve rod positioning hole (1) is arranged below valve opening (12), valve opening (12) and valve rod positioning hole (1) are concentric, but the diameter of valve rod positioning hole (1) is slightly littler than valve opening (12) diameter, general little 15-20mm, promptly one step is arranged, can not fall into valve rod positioning hole (1) after making spring (13) be inserted in valve rod at two hole connecting places.The utility model is under closed state, and stem through-hole (10) center deducts the shaft length that stretches in the valve rod positioning hole (1) to the degree of depth that the distance at valve hole center equals valve rod positioning hole (1).At this moment, spring (13) does not stress, and the lower end of valve rod has one section to stretch in the valve rod positioning hole (1).Its built-in length is 3-5mm.Be the schematic representation under the closed state shown in the accompanying drawing.Because valve rod (11) be the cylindrical body of mid diameter greater than the two ends diameter, therefore on valve rod (11), there are two shaft shoulders, the effect of the last shaft shoulder to be, and gland (4) mating reaction, preventing effect, and make valve rod (11) ejection owing to spring (13); The effect of the following shaft shoulder is, and the step cooperation of valve opening (12) bottom, and spring (13) is played position-limiting action.In the middle of the gland of the present utility model (4) circular groove is arranged, a seal ring (8) is arranged in groove, a sealing gasket (9) is arranged below gland (4).Pedal of the present utility model (6) is to be fixed on the valve rod (11) with pedal screw (7).
Installation of the present utility model is such: the lower end of earlier spring (13) being inserted in valve rod (11), then valve rod is inserted in the valve opening (12), again with sealing gasket (9) and gland (4) that seal ring (8) are housed from valve rod (11) top be inserted in (gland (4) go up and valve body (3) on several screw holes are arranged respectively), and compress with several gland screws (5), at last pedal (6) is fixed on the top of valve rod (11) with pedal screw (7).The upper length of valve rod (11) can be selected the different length of design according to different needs.The utility model valve body (3) adopts the casting once-through, and when the lower end of valve rod (11) was forced into the bottom of valve rod positioning hole (1), spring (13) was no more than compression limit.At valve hole (2) two ends screw thread is arranged respectively, in order to be connected with water pipeline and outlet pipe.
Working principle of the present utility model is: when with outside when defeating pedal (6) (generally speaking with foot-operated, also can use a weight in case of necessity), valve rod (11) moves down, following shaft shoulder pressing spring (13), when valve rod (11) was displaced downwardly to the bottom of valve rod positioning hole (1), stem through-hole (10) and valve hole (2) were concentric.At this moment, water just flows into outer pipe from water pipeline.When water not, as long as remove external force, promptly lift pin, under the effect of spring (13), valve rod to be upspring, be in closed state this moment again, and for the sake of assurance, the sealing density ring in the gland can adopt secondary or three grades of sealings.
Advantage of the present utility model is: simple in structure, cost is low, easy to manufacture, be installed in the water supply pipe, in the particularly public tap water pipeline, even water tap damages or does not install water tap, also can prevent water waste effectively, and it is easy to use, not fragile, have only when human is ridden upward there are flowing out,, turn off the tap even forget when people one leaves, or water tap damages, also can not there are flowing out, and installation is also convenient, as long as water pipeline and outer pipe are received the valve hole two ends respectively.
