The utility model is characterized in that water can run through under any pressure; the utility model not only is the switch main valve, but also is the decompressing and unloading valve with good unloading effect; and the utility model can prolong the service life of the water device with the advantages of saving water, flexible mechanism and convenient using.
Description
The mechanical device of using on a kind of water supply pipe of technical field belongs to valve type.
The present pressure maintaining valve on the market of background technique can only use separately on the water appliance of water heater or washing machine and so on, can not use as the tap water main valve.The structure of such pressure maintaining valve is between the upper and lower cavity spool bore to be arranged in the valve body, the valve rod upper end that is positioned at spool bore central authorities is fixed with the cartridge cover of being made up of circle metal plate and rubber sheet gasketing, the valve rod lower end is fixed with leather cup, leather cup is separated into water flowing chamber and spring chamber with cavity under the valve body, the pressure spring that supporting valve rod is arranged in the spring chamber, the valve body upper end is water supply connector, and valve body left end water output connector is connected with valve body water flowing chamber.It is to utilize the mutual balanced action of water inlet pressure between axial pressure that produces on the cartridge cover and spring power, distance between automatic regulating valve core cap and the spool bore, promptly adjust mouth of a river open degree, thereby realize the basicly stable of water outlet pressure, reach the effect of water outlet voltage stabilizing.The precondition of using such pressure maintaining valve is that the water inlet pressure from water factory must fluctuate in a normal range (NR).If water inlet pressure exceeds normal range (NR) and bigger than normal, cartridge cover is moved down the axial pressure that the pressure of intaking so produces on cartridge cover and complete closed is lived cartridge cover, causes the anhydrous phenomenon that goes out.The significant deficiency of Here it is such pressure maintaining valve, the pressure of leaveing no choice but intake by the time drop to normal value when following, just can have water to use.Just because of this, such pressure maintaining valve only is applicable to single water appliance voltage stabilizing, must not use as domestic running water pipeline main valve.
Second defective of such pressure maintaining valve is hydraulic pressure instability in the water flowing chamber, and when water inlet pressure was excessive, spool bore was closed, and hydraulic pressure diminishes in the water flowing chamber; When water inlet pressure diminished, spool bore was opened, and water enters the water flowing chamber and makes pressure increase in the chamber, and fluctuation ratio is bigger, and promptly voltage regulation performance is not good enough.
The summary of the invention the purpose of this utility model provides a kind of decompression voltage stabilizing and switch dual purpose water-saving main valve, accomplishes that voltage regulation result is good, and all water flowings under any intake pressure can be used as the switch main valve.
Technological scheme is that existing pressure maintaining valve is improved, be about to the piston that cartridge cover changes down band caulking gum pad into, piston is positioned at the piston cavity on the valve gap, be equipped with rubber seal ring between piston and piston cavity, be with the switch nut on the piston cavity outside thread, between water supply connector of valve body right-hand member and the valve body upper plenum water inlet arranged.
Working principle is that piston position and spring power determine the strong rating value of hydraulic pressure jointly.Under the normal water situation, tap water flows into the valve body upper plenum by water supply connector through the water inlet, enter valve body water flowing chamber through spool bore again, is flowed out by left side joint.When not needing water promptly to close the water appliance valve, if influent pressure is powerful in rating value, the pressure of water will overcome the elastic force of pressure spring in the valve body water flowing chamber so, and valve rod is descended, and drive piston and caulking gum pad and seal spool bore.Open water appliance valve if need water this moment, and the water the water flowing chamber in will flow out, i.e. hydraulic pressure minimizing in the water flowing chamber, and the elastic force of pressure spring will make the valve rod rising, piston is risen a little and leave the spool bore certain altitude.This height is determined by water inlet pressure: influent pressure is powerful, and the height that leaves is little; Water inlet pressure is little, and the height that leaves is big, promptly adjusts mouth of a river open degree, and this is stable to realize the water outlet pressure strong basis, reaches decompression, the purpose of voltage stabilizing.
Compared with prior art, the utility model has following characteristics:
1, because water inlet pressure can not produce pressure on the valve rod axial direction, much no matter intake pressure has, all can water flowing, all can not produce the phenomenon that makes piston close spool bore all the time.As long as a water, the water in the water flowing chamber will flow out, and hydraulic pressure reduces, and valve rod and the piston certain altitude that will rise under the effect of pressure spring elastic force leaves spool bore and water flowing.Therefore the utility model can play decompression, pressure stabilization function, can be used as main valve and uses.
2, because the utility model can play decompression, pressure stabilization function, therefore the water facilities (water pipe, switch, water heater, washing machine, closet etc.) to its back plays a protective role, and promptly prolongs and uses the drainage facility life-span, saves family expense.
3, a valve is dual-purpose, both can be used as decompression voltage stabilizing main valve, can be used as the switch main valve again.When screwing switch and use nut, piston will seal spool bore by rubber sheet gasketing and promptly turn-off the water source.If when unscrewing switch and using nut, then open the water source, use as decompression venting valve.
4, the flow velocity of decompression back water will slow down, and will use a lot of water less when flushing device for toilet, play water-saving function.
5, because piston takes regular exercise, be not easy the incrustation scale that condenses, so Push And Release is all very flexible, very easy to use.
Description of drawings Fig. 1 is decompression voltage stabilizing and switch dual purpose water-saving main valve structural representation.
Embodiment as shown in Figure 1, the utility model comprises valve body 1, on the valve body 1, between the following cavity spool bore 14 is arranged, valve rod 3 is erected at spool bore central authorities, valve rod 3 lower ends are fixed with leather cup 4, leather cup 4 is separated into water flowing chamber and spring chamber with 1 time cavity of valve body, the pressure spring 5 that supporting valve rod 3 is arranged in the spring chamber, valve body 1 left end water output connector 11 is connected with valve body 1 water flowing chamber, it is characterized in that piston cavity 61 is arranged on the valve gap 6, be with switch nut 7 on piston cavity 61 outside threads, the piston 8 that is positioned at piston cavity 61 is fixed on valve rod 3 upper ends with threaded connection mode, be fixed with rubber gasket 9 between piston 8 and the valve rod 3, be equipped with packer ring 2 between piston 8 and the piston cavity 61, between valve body 1 right-hand member water supply connector 12 and valve body 1 upper plenum water inlet 13 is arranged.
In order to set the specified pressure of water in the water flowing chamber better, present embodiment is provided with interior threaded hole at valve body lower cover 15, and pressure spring 5 is located on the adjustable spring seat 51, and adjustable spring seat 51 rotation sets are in lower cover 15 lower end interior threaded holes.Regulate adjustable spring seat 51, can change the length of pressure spring 5, promptly change the elastic force of pressure spring 5, to reach the purpose that changes the pressure of water in the water flowing chamber.
In the present embodiment, the cross section of packer ring 2 is circular.We also can adopt cross section is the packer ring of matrix, to reduce the requirement on machining accuracy to piston 8.
