Abstract
The utility model relates to a toilet bowl flushing valve of a cistern, which is mainly composed of a valve body, a piston column, a regulating screw, a floater, etc. The utility model is characterized in that the middle of the valve body has a hole penetrating from top to bottom on the valve body, the piston column which can suspends from top to bottom is arranged in the hole, and the middle of the piston column has a drain hole. The piston column can move freely in the hole without water flow. Water can flow into the cistern only when the drain hole of the piston column and a water outlet hole positioned along the groove direction of the valve body are in the same line; in reverse, the water flow is blocked. The utility model can replace a float valve of an old cistern. The utility model has the advantages of small size, simple structure, no deformation, no leakage, long service life, low cost, etc., and can automatically control the valve by utilizing self buoyancy.
Description
The utility model relates to water system, particularly a kind of Water valve with piston rod that is used for elevated tank.
Be used for the water system switch that water tank restricts water supply automatically at present and generally adopt float valve.This switch is to utilize the principle of mechanical lever to move.Comprise formations such as water outlet body, travel(l)ing rest, hollow float, ball float pole, protruding plug and rubber washer and adjustment spiral pin.Travel(l)ing rest is fixed on the water outlet body, the support ball float pole of ining succession, and hollow float is fixed on the pole, the lifting along with the height of water level in the water tank.When water level increased, ball float raise simultaneously, when reaching a certain position, and the protruding plug before the travel(l)ing rest the other end spiral pin compressing water outlet, protruding rubber washer has beyond the Great Wall covered water outlet, thereby has closed current.When drawdown, float valve descends thereupon, and the support spiral shell is happy no longer oppresses protruding plug, and rubber washer leaves water outlet, water flows out again.From above-mentioned motion principle, the existing problem of this float valve is: 1, and complex structure, volume is big, cost is high, often is immersed in the water because of its movable part simultaneously, and is with the passing of time fragile.2, ball float pole is longer, is subjected to hydraulic pressure again for a long time, and easy deformation causes protruding plug compressing tightly not cause and leaks.3, hollow float very easily breaks because of being subjected to hydraulic pressure for a long time, in case break, then loses the function of closing current.4, after float valve is used, as can not get frequent maintenance service, adjust spiral pin and protruding plug easy-to-rust, cause problems such as can't adjusting and be not closed completely and cause leaking.
The purpose of this utility model is at the problems referred to above, provide a kind of simple in structure, cost is low, can utilize the piston type water valve of self buoyancy autocontrol valve.
The purpose of this utility model is achieved by the following scheme, Water valve with piston rod comprises loam cake 1, adjusts screw 2, piston column 3, ostium excurrens 4, goes into water channel 6, valve body 7, float 8, locating slot 9 constitute, in the middle of valve body 7, be provided with the hole of up/down perforation, the piston column 3 of low suspension on the energy is arranged in the hole.The external diameter of the aperture of valve body and piston column is very identical simultaneously, and piston column can be free therein movable, but can not flowing water.The left and right sides of valve body is provided with the osculum 4 that can connect the valve body aperture, also be provided with simultaneously the identical discharge orifice 5, aperture with the osculum 4 of valve body in the centre of piston column 3, thereby when both coexisted a line, water is promptly negotiable.When both during not at a line, just blocked current, played on-off action.
In the technical solution of the present utility model, the two ends up and down of said piston column 3 respectively are provided with screw, and the upper end connects adjusts screw 2, and the lower end is connected with float.The lower end inner hole wall of said valve body 7 is provided with a locating slot 9, can make the projecting point of piston column 3 bottoms up and down along this groove, simultaneously the slewing area of limited piston post.
The utility model compared with prior art, have simple in structure, volume is little, cost is low, easy for installation, not yielding, ne-leakage, long service life, can utilize self buoyancy autocontrol valve, characteristics such as regulate and easy to maintenance.
Below in conjunction with accompanying drawing the utility model is illustrated,
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, piston valve is by loam cake 1, adjusts screw 2, piston column 3, osculum 4, goes into water channel 6, valve body 7, float 8, locating slot 9 form.Be provided with the aperture of a up/down perforation in the centre of valve body, be provided with a piston column that can fluctuate 3 in the hole, valve block internal diameter and piston column external diameter are very identical, and piston column can be free movable in the hole, but water is non-negotiable.Valve body 7 left and right sides are provided with the aperture 4 that connects valve body, and this hole is identical with the discharge orifice 5 of setting in the middle of the piston column 3, and when both coexisted a line, water was promptly negotiable, when both misplace, had just blocked current, had played on-off action.Two ends up and down at piston column have a pair of screw, and the upper end connects adjusts screw 2, and the lower end connects float 8, and the size of the water yield and the height of water level are adjusted screw 2 respectively and float 8 can be realized.On the inwall of valve body lower portion, be provided with a locating slot 9, the projecting point of piston column bottom slided up and down, simultaneously the slewing area of limited piston post along this groove.
Under static state, piston column discharge orifice and the valve body flowing flux line that coexists, water enters water tank from water inlet.When cistern water level arrived certain amplitude, float 8 was subjected to the holder power of water, drove piston column and moved up, piston column discharge orifice and the dislocation of valve body flowing flux, water can't circulate, after water tank discharges water, and drawdown, float moves down, the flowing water duct line that coexists, and water flows into water tank again.
The utility model is suitable for the water system switch that elevated tank or side are fit into the mouth of a river.During installation whole complete piston valve directly is fixed in original water tank with nut, adjusts float according to different needs again, make cistern water level reach requirement and get final product.
