Abstract
The utility model discloses an automatic water saving valve capable of being installed and used on a time-lapse flush valve product, which comprises a water saving valve casing. A piston gland fixedly mounted by a screw thread is arranged inside the upper part of the water saving valve casing. The piston gland is of a hollow structure and is provided with a water inlet passage. A cone piston is arranged in the water saving valve casing. A space is reserved between the cone piston and the water saving valve casing to form a division passage. The cone piston is also of a hollow structure and is provided with a water outlet passage. The water inlet passage is communicated with the water outlet passage. Both the inside of the lower part of the water saving valve casing and the outside of the upper part of the cone piston are bulged to form bosses. A pressure spring is sleeved outside the cone piston. Two bosses are used as limit devices of the pressure spring. The cone piston is provided with an opening communicated with the water outlet passage and the division passage. The maximum diameter of the cone end face of the cone piston is equal to or more than the diameter of the water stop end face of the water outlet end of the water saving valve casing. Other diameters of the cone end face of the cone piston are less than the diameter of the water stop end face of the water outlet end of the water saving valve casing. A first sealing ring is also arranged between the upper part of the cone piston and the water saving valve casing.
Description
Technical field
The utility model relates to a kind of ability and is fit to the automatic water-saving valve that time-delay flushing valve series products is installed and used, and relates in particular to a kind of water flow and stablizes effective water-saving automatic water-saving valve.
Background technique
Time-delay valve in the past; It mostly is perforate on buoyancy aid; On the hole, cover filter screen then, water gets into the time-delay chamber through filter screen from the hole on the buoyancy aid, and the time has been grown filter screen and stopped up by the foreign material in the water easily; The water level of water that water can not get into time-delay chamber or entering is not enough, does not have the effect that the time-delay control of reliable and stable discharges water; Also have plenty of in addition on the main body inner wall of the cooperation place of main body and buoyancy aid and have gutter, such gutter is not easy to be stopped up by foreign material, the water inlet of time-delay chamber smoothly, but because gutter leaves on main body inner wall, and processing is big, cost of production is high.
At present, have time-delay and wash, close automatically the valve series products of using with the flushing device for toilet of flow control function, a function with manual control flow rate.Flow was too small when hydraulic pressure was low when bath, and just effect is dashed in influence; Flow was excessive when hydraulic pressure was high, the serious waste water resources.And hand control valve is because its most volume is bigger than normal, and complex structure is unfavorable for the control of product cost.
Have and see and this, the applicant's independent research a kind of water-outlet quantity that can guarantee stable, and guarantee effectively using water wisely under the developing result prerequisite.
Summary of the invention
The utility model technical problem to be solved is the defective that overcomes existing technology, provides a kind of and can stablize water flow, guarantees effective water-saving automatic water-saving valve under the developing result prerequisite.
It is that a kind of ability is fit to the automatic water-saving valve that time-delay flushing valve series products is installed and used that the utility model solves the technological scheme that its technical problem adopted; Comprise a water saving shell; Wherein aforesaid water saving shell upper inboard is provided with the hard-wired piston gland of screw thread, and piston gland is that hollow structure forms intake tunnel; In the water saving shell, be provided with the tapered piston that is positioned at the piston gland below, leave the space between tapered piston and the water saving shell and form split channel, tapered piston also forms exhalant canal for hollow structure, and intake tunnel and exhalant canal communicate; Water saving outer casing underpart inboard is protruding with a boss, and the tapered piston upper outside also is protruding with a boss, and the outside of tapered piston is with the pressure spring between water saving shell boss and tapered piston boss, and two boss are spacing as pressure spring; Tapered piston is provided with open communication exhalant canal and split channel, and the tapered end face maximum diameter of tapered piston is equal to or greater than the sealing end face diameter of water saving shell waterexit end, and other diameters of tapered end face are less than the sealing end face diameter of water saving shell waterexit end; Also be provided with first seal ring between tapered piston top and the water saving shell, the water saving shell outside is with second seal ring of realizing sealing with outlet conduit.
As the further design to the aforementioned techniques scheme: aforesaid water saving shell upper is outward extended with and the annular boss of outlet conduit as limit mounting.
The basic principle of operation of water-saving valve is: be in when closing at water-saving valve, pressure spring is not compressed, and tapered piston is in initial static, this moment split channel to cross the water cross section maximum, and cross the water cross section greater than exhalant canal; When water-saving valve is opened; When pressure of supply water during less than minimum operationg pressure differential, tapered piston 2 is in initial static, and a part of water flow flows out from split channel; Another part water flow flows out from exhalant canal, and water flow is split channel and exhalant canal flow sum; When pressure of supply water during greater than minimum operationg pressure differential; Tapered Piston Compression spring; Piston moves to the waterexit end, and split channel must be crossed the water cross section and reduce with the pressure reduction increase, and corresponding water flow reduces; The water flow of exhalant canal then increases and increases in a small amount with pressure reduction, but the water flow sum of split channel and exhalant canal still remains unchanged; When pressure of supply water during greater than maximum operating pressure differential, split channel is closed, and water flow is all flowed out by exhalant canal.
In sum, the automatic water-saving valve that time-delay flushing valve series products installs and uses of being fit to of the utility model is compared with automatic water-saving valve of the prior art and is had following advantage:
One, simple in structure, the big parts of whole water-saving valve are made up of water saving shell and tapered piston basically;
Two, water flow is stable, no matter hydraulic pressure what, its water flow is all quantitative, water flow is not affected;
Three, using water wisely, because its water flow is stable, water flow can be not too much, under the prerequisite that guarantees developing result, practiced thrift water effectively;
Four, volume is little, and is easy for installation, and water-saving valve directly is installed in the outlet conduit, need not outlet conduit is changed, and directly installation just can;
Five, sturdy and durable, water-saving valve is full copper valve body, has the piston and the stainless copper pressure spring of sealed type, detects sensitivity, and work is balanced during use.
