Abstract
The utility model relates to a pressure reducing and water saving valve for city water, mainly comprising a valve body, and a valve core, a water preventing cushion, a four-edge guide bar, a guide plate, a pressure-reducing valve diaphragm, a compression nut, a relief spring and an upper cover plate which are arranged inside the valve body through series connection. The valve can automatically control any hydraulic pressure set which is lower than the hydraulic pressure of running water; when the hydraulic pressure of the running water is lower than the set pressure, a valve is directly communicated and does not play a part in pressure reduction; when the hydraulic pressure of the running water is higher than the set pressure, the hydraulic pressure of the running water is reduced by fluid-pressure loss caused by utilization of the tension of the relief spring and the change of a discharge cross section, and the hydraulic pressure in the valve core and a water application container arranged on the rear of the valve core is kept within a certain value range, thereby the device can be used safely. The utility model can be widely used as a water feeding valve of a solar water heater, and as a pressure-limiting valve and an antispray water saving valve of a small-scale pressure vessel.
Description
The utility model relates to a kind of tap water pressure reducing and water saving device.
The city tap-water water supply system all is to adopt engine driven supercharging now, so tap water is different with the pressure of asynchronism(-nization) tap water because of its residing position to every user Shi Hui, some places pressure is big, some places pressure is little, raising along with people's living standard, some device needs not have pressure or low pressure water supply in the family, as solar water heater and family expenses waste-heat oven etc., other public places, reduce tap water hydraulic conserve water resource in a large number, and the water valve that we use does not now possess stable buck functionality, only play on-off action, the small-sized household waste-heat oven directly inserts tap water, very easy its damage, the SBTS regulation of causing of the variation of tap water pressure, the working pressure of this type of minute-pressure force container requires below 0.1Mpa, this shows, do not solve the hydraulic pressure problem of tap water, this class minute-pressure force container is impossible guarantee safe handling.What have that solar water heater adopts now is the float type feed valve again, and water completely promptly closes, can not continuous water supply, take a lot of trouble very much to require great effort.In a word, do not have a kind of device can stablize tap water pressure well now, guarantee some household equipment installation securitys use tap water.
The purpose of this utility model aims to provide a kind of compact structure, can realize continuous water supply, can realize the device of tap water decompression, voltage stabilizing, water saving again, fundamentally solves the specific demand that family's minute-pressure container need reduce pressure with tap water.
The technical solution of the utility model is to add cartridge spool, guide rod and spring and valve film in valve body.The one, utilize valve body to cross water sectional area and spool and cross the variation of water sectional area and reduce tap water pressure; The 2nd, by the reduction valve film tension force of relief spring is passed to the tap water fluid, offset part hydraulic pressure and stablize hydraulic pressure.
Compared with prior art, the utility model has following characteristics:
1, reduces tap water pressure significantly, guarantee the safe in utilization of minute-pressure force container.
2, reduce tap water pressure, help the conserve water resource.
Fig. 1 is the structural representation of the utility model Running water relief valve;
Fig. 2 be the utility model Running water relief valve the A-A sectional view.
Below in conjunction with annexed drawings set forth structure of the present utility model and working principle.
As shown in the figure: the spool 5 that the utility model includes valve body 1 and is mounted in it, the tap water water intake is provided with the lower end of valve body 1, spool 5 and valve body 1 lower end are by 2 sealings of O type circle, spool 5 is built-in with guide plate 9, four rib guide rods 12 pass pad 3, rubber cushion 4 blocks water, spool 5, guide plate 9 and reduction valve film 6 backs compress with nut 7, the edge of reduction valve film 6 is fixed on the valve body 1 by upper end cap 1 simultaneously, between upper end 10 and nut 7, relief spring 8 is housed, be evenly equipped with a plurality of water passage holes 11 on the guide plate 9, tap water flows into from the lower end through the rubber cushion 4 that blocks water, the space enters spool between four rib guide rods 9 and the spool 5, and flows out from side direction.
Working principle is as follows: when container does not have tap water to flow out, be referred to as the static pressure state, tap water enters in the spool 5 and by the water passage hole 11 on the guide plate 9 reduction valve film 6 is held up, reduction valve film 6 is subjected to the effect of the tension force of relief spring 8 simultaneously, when tap water to the holder power of reduction valve film 6 during greater than the pressure of 8 pairs of reduction valve films 6 of relief spring, four rib guide rods 12 are moved up by band, the rubber cushion 4 that blocks water seals water intakes, makes that the pressure in spool 5 and the container is the pressure of tap water and the pressure difference between relief spring 8 tension force.
When container is opened, when promptly having tap water to flow out by reduction valve, be referred to as the dynamic pressure state, spool 5 internal pressures reduce, under the tension force effect of relief spring 8, four rib guide rods 12 drive reduction valve film 6 and move down, at this moment the water intake that the rubber cushion 4 that blocks water seals is opened, under action of pressure, water is rapidly by the water channel in the valve, because valve body 1 water intake sectional area is much larger than the water intake sectional area of rubber cushion 4 sealings that blocked water, therefore increase in that this water inlet water velocity is anxious, square being directly proportional of the pressure loss herein and flow velocity, in this moment spool 5 and the interior hydraulic pressure of the container pressure that is tap water deduct herein loss of pressure head, hydraulic pressure when generally speaking, the hydraulic pressure during static pressure is greater than dynamic pressure.
The utility model still is a kind of full-automatic decompression constant voltage water-saving valve.
