Abstract
The utility model relating to the flow controlling valve technique comprises a shell provided with an airproof cover, a water inlet hole, and a water outlet hole. The middle portion of the airproof cover is provided with a pressure regulating screw nut. A rubber isolation arranged between the airproof cover and the shell is provided with a connecting rod, the lower portion of the connecting rod is connected with a braking tongue. A compress spring is arranged between the pressure regulating screw nut and the connecting rod. The front portion of a shift crosspiece connected with the braking tongue is fixedly connected with a sealing rubber plug provided with taper angle. The sealing rubber plug is engaged with the water inlet hole. The utility model achieves simple structure, low cost and stable pressure inside the valve shell.
Description
The utility model relates to the excess-flow valve technical field, is specifically related to a kind of voltage stabilizing by water valve.
At present, when liquid stabilizing valve commonly used can only reach water by this valve, the pressure of this valve is consistent, when the Work container discharge opening of this valve end was closed, water continued to enter in the Work container with pressure of supply water, and Work container is damaged, as the patent No. is 96207836, its title is: decompression venting valve, and he is by valve body, valve gap, diaphragm plate, diaphragm, piston, valve seat, valve rod is formed, it is characterized in that, at valve body provided upstream conduit and needle-valve, be communicated to diaphragm top, establish connecting tube connection ball valve, pilot valve in the valve body downstream to diaphragm top.Its shortcoming is: no matter the fluctuation of inlet pressure and the variation of rate of discharge, always be output as constant compression force, water continues to enter in the Work container with pressure of supply water, and Work container is damaged, and complex structure, cost height.
The purpose of this utility model just provides a kind of voltage stabilizing simple in structure, that cost is low and the Work container internal pressure is stable and ends water valve.
To achieve these goals, the technical solution of the utility model is: it comprises voltage stabilizing water valve housing, the housing two ends have water intake, water outlet, the housing upper end is equipped with sealing cover, the sealing cover middle part is equipped with the pressure adjusting nut, it is characterized in that: between sealing cover and the housing liquid sealing be equipped with glue every, glue is installed with connecting rod every last liquid sealing, between pressure adjusting nut and connecting rod, pressure spring is installed, the connecting rod lower hinge has the braking tongue, and braking tongue afterbody is connected with and moves shelves, moves the shelves front end and is fixedly connected with the sealing plug, described sealing plug has tapering, and the sealing plug matches with water intake.
The utility model adopts the thing such scheme, between sealing cover and the housing liquid sealing be equipped with glue every, glue is installed with connecting rod every last liquid sealing, between pressure adjusting nut and connecting rod pressure spring is installed, the connecting rod lower hinge has the braking tongue, and braking tongue upper end is fixedly connected with moves shelves, the lower end is hinged with mobile shelves, move the shelves front end and be fixedly connected with the sealing plug, described sealing plug has tapering, and the sealing plug matches with water intake.Size according to intake pressure, glue every on move or descend, slit between sealing plug and the water intake reduces or increases, make the pressure stability in the Work container constant, when water outlet was closed, the slit between sealing plug and the water intake was air-tight state, stops into water, make the pressure stability in the Work container constant, and simple in structure, cost is low.
Describe the utility model in detail below in conjunction with drawings and Examples;
Accompanying drawing shows the utility model embodiment's main sectional view;
The utility model comprises that voltage stabilizing ends water valve housing 5, housing 5 two ends have water intake 14, water outlet 15, housing 5 upper ends are equipped with sealing cover 2 by screw 13, sealing cover 2 middle parts are equipped with pressure adjusting nut 12, liquid sealing is equipped with glue every 9 between sealing cover 2 and the housing 5, glue is equipped with glue every gusset plate 10 every 9 upper surfaces, glue liquid sealing on 9 is installed with connecting rod 1, between pressure adjusting nut 12 and connecting rod 1, pressure spring 11 is installed, connecting rod 1 lower hinge has braking tongue 6, braking tongue 6 upper ends are fixedly connected with moves shelves 7, lower end and mobile shelves 7 are hinged, move in the shelves 7 and are provided with mandrel 4, and mobile grade 7 front ends are installed with sealing plug 3, described sealing plug 3 has tapering, and sealing plug 3 matches with water intake 14 in water intake 14 outsides.
During off working state, at first set steady pressures by pressure adjusting nut 12 because the effect of pressure spring 11, make glue every 9, connecting rod 1 and braking tongue 6 be in lowest order, braking tongue 6 forces and moves shelves 7 and sealing plug 3 outer moving, and sealing plug 3 and water intake 14 are broken away from; During water flowing, voltage stabilizing equates with pressure of supply water by water valve housing 5 internal pressures, its pressure is during greater than setting pressure, and compressing glue moves on 9, and pressure spring 11 shortens, drivening rod 1, braking tongue 6, under the effect of braking tongue 6 lever, to move in shelves 7 and the sealing plug 3 and move, the gap of water intake and 14 sealing plugs 3 dwindles, the water inlet response reduces, and voltage stabilizing reduces by water valve housing 5 internal pressures.When water outlet is closed, outside water supply makes voltage stabilizing end the increase of water valve housing 5 internal pressures, compressing glue moves on 9, pressure spring 11 shortens, drivening rod 1, braking tongue 6 under the effect of braking tongue 6 lever, move in shelves 1 and the sealing plug 3 and move, water intake 14 is air-tight state with sealing plug 3, makes with voltage stabilizing and remains setting pressure by the Work container that water valve is connected.
