Abstract
The utility model relates to a pressure stabilizer for household water. The utility model is characterized in that a valve body is divided into a pressure stabilizing chamber and a high pressure chamber by a main valve port, wherein, an enclosed cavity body composed of a fixing seat and a rubber barrel is arranged in the pressure stabilizing chamber, and a pressure stabilizing spring is arranged in the enclosed cavity body; a pilot valve is arranged in the high pressure chamber. A main valve film is arranged corresponding to the main valve port, and a pilot valve rod passes through an outlet pipe and the main valve port of a pilot valve seat. The top end of the pilot valve rod is butted with the rubber barrel, the lower part of the pilot valve rod is fixedly connected with a pilot valve core, and the bottom end is butted with a pressure spring. A pilot valve cavity seat is fixedly connected to the valve body, and a pilot valve inlet port is arranged at the bottom of the pilot valve cavity seat. The utility model can reduce water pressure, is matched with water appliances of an induction water valve, etc., and can increase the operational reliability and the service life of the appliances.
Description
The utility model relates to the tap water stable-pressure device.A kind of stable-pressure device that is particularly useful for residential water of more specifically saying so.
The city tap-water system supplies water by unified hydraulic pressure.But family's residence physical features has height, and the floor of living has height, so the hydraulic pressure of every family differs greatly, whenever differs 10 meters with the water spot height, and pressure just differs an atmospheric pressure.Like this, the dwelling house that hydraulic pressure is high, seepage appears in running water pipe joint and water appliance easily, even damaged.Especially use battery-powered induction water valve, hydraulic pressure is too high will to influence the dependability of water valve, reduce its application life, increase power consumption.In addition, at high hydraulic pressure place, water discharge of water faucet is too anxious also makes troubles to use.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of miniaturization, residential water stable-pressure device simple in structure are provided.
The purpose of this utility model is achieved through the following technical solutions:
Design feature of the present utility model is in valve body, be separated out pressure stabilizing chamber that is positioned at water outlet side and the hyperbaric chamber that is positioned at influent side by primary valve, in described pressure stabilizing chamber, by holder and the rubber tube that is enclosed within outward on the internal layer cylindrical body of holder constitute closed cavity, pressure-stabilizing spring is set in the cavity; In described hyperbaric chamber, corresponding to the primary valve setting is the main valve film that is driven by guide's valve seat, guide's valve rod is through the outlet pipe and the primary valve of guide's valve seat, its top is butted on rubber tube, its underpart connects firmly guide's spool, the bottom is butted on stage clip, and guide's valve pocket seat connects firmly on valve body, and the pilot valve inlet is offered in its bottom.
Compared with the prior art, the utlity model has following advantage:
1, the utility model can obtain different voltage stabilizing values by selecting the pressure-stabilizing spring of different pressures.Structurally there is not the investigation mission outside the city or town element, good integrity, reliable operation, the pressure setting range is big, applied range.
2, the utlity model has the effect of step-down, voltage stabilizing, be used the induction type water valve, can reduce power consumption greatly, improve water valve functional reliability, increase the service life.
3, the utility model is simple in structure, cost is low, can be widely used in average family.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model voltage stabilizing status architecture schematic diagram.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to Fig. 1, present embodiment is in valve body 1, is separated out pressure stabilizing chamber 4 that is positioned at water outlet side 3 and the hyperbaric chamber 6 that is positioned at influent side 5 by primary valve 2.
In pressure stabilizing chamber 4, constitute closed cavity by holder 7 and the rubber tube 8 that is enclosed within on the internal layer cylindrical body of holder 7 outward, pressure-stabilizing spring 9 is set in the cavity.In the present embodiment, in closed cavity, be provided with pressure-bearing piston 12, pressure-bearing piston 12 is fixed on the bottom of rubber tube 8.Shown in Fig. 1, holder 7 is a tubular, is fixedly installed in the pressure stabilizing chamber 4, and pressure-bearing piston 12 can slide up and down along the cylindrical body inside wall of holder 7.
In hyperbaric chamber 6, pilot valve is set, corresponding to primary valve 2 settings are the main valve films 11 that driven by guide's valve seat 15, guide's valve rod 10 formerly forms the pilot valve effluent pipe mouth through the outlet pipe 14 and the primary valve 2 of guide's valve seat 15 between the inside wall of guide valve seat outlet pipe 14 and the guide's valve rod 10.The top of guide's valve rod 10 is butted on rubber tube 8, and its underpart connects firmly guide's spool 13, and the bottom is butted on stage clip 16, and guide's spool 13 is used for shutoff pilot valve effluent pipe mouth, promptly closes pilot valve.Guide's valve pocket seat 17 connects firmly in valve body 1, and pilot valve inlet 18 is offered in its bottom.
Figure 1 shows that and use water state.At this moment, primary valve 2 is opened, and influent side 5 connects with water outlet side 3.
Figure 2 shows that the voltage stabilizing state.When closing with water tap, the pressure in the pressure stabilizing chamber 4 increases gradually, and when rubber tube 8 suffered hydraulic pressure surpassed the elastic force of pressure-stabilizing spring, rubber tube moved on 8 bottom surfaces, and by pressure-bearing piston 12 compression pressure-stabilizing springs 9.At this moment, guide's valve rod 10 loses support, under the effect of stage clip 16, upwards promotes within it, drives guide's spool 13 with the shutoff of pilot valve delivery port, and pilot valve is at first closed.Thereupon, the pilot valve cavity pressure increases, and the main valve film 11 formerly effect of guide valve seat 15 pushes away on descending rapidly, with primary valve 2 shutoff.So far, pressure stabilizing chamber 4 is cut off with hyperbaric chamber 6, and pressure stabilizing chamber 4 remains on the force value that pressure-stabilizing spring 9 is set.When water tap was opened, because the pressure in the pressure stabilizing chamber 4 at first is released, pressure-stabilizing spring 9 returned to form, and guide's valve rod pushes away for 10 times, at first opens pilot valve, opens primary valve 2 then.
