Background technique
At present, the pressure of supply water problems of too that causes for a solution building floor difference generally has diaphragm type direct acting pressure valve and constant pressure and constant streaming water economizer.The structure of diaphragm type direct acting pressure valve is to overcome acting force of the spring by hydraulic pressure that diaphragm bears to realize pressure-reducing function; The constant pressure and flow water economizer is straight channel type, two kinds all for a change water flow section amass to realize the pressure reducing and water saving purpose, but limited to the water demand amount after the pressure regulation.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can regulate sectional area realize the reducing pressure pressure regulation unsteady flow water economizer of unsteady flow automatically.
The object of the present invention is achieved like this: a kind of pressure regulation unsteady flow water economizer, comprise the groove cover, piston and spring, the groove cover is cylindrical shell, in the groove cover piston is installed, the groove cover comprises sleeve and supporting frame, sleeve one end is through hole, the other end is provided with the supporting frame of taking the water hole out of, the supporting frame center is through hole, sleeve lateral wall is provided with some slotted eyes, piston comprises piston sheet and piston rod, and the piston sheet is divided in two parts slotted eye, and piston sheet and sleeve lining junction plane are slidingly matched, piston rod and supporting frame endoporus junction plane are slidingly matched, piston can slide relatively with the groove cover, and spring housing is contained on the piston rod between piston sheet and the supporting frame, and both ends of the spring contacts with the end face of piston sheet and supporting frame respectively and links to each other.
Be to realize products perfection, improvement, raising combination property of the present invention, its further step is that the piston rod afterbody with the supporting frame fit is equipped with limit stoper; The slotted eye cross section is V-type or wedge shape, and slotted eye quantity is 2-4; Osculum evenly distributes on supporting frame, and osculum quantity is 2-4; When water economizer is in off working state, be positioned at the long-pending 1%-5% that accounts for the slotted eye total sectional area of slotted eye partial cross section of feed-water end piston sheet one side; Groove sleeve wall thickness 1-2.5cm; Sleeve outer wall is equipped with some seal rings.
The present invention adopts groove to put to be provided with slotted eye, and the technological scheme of piston and spring is installed in the groove cover, has solved defectives such as current loss that the pressure difference of front end and back end in the present water economizer causes and pressure loss.
The beneficial effect that the relative prior art of the present invention produces is:
1, regulate water inlet and outlet pressure reduction automatically, realization pressure and flow are regulated automatically, satisfy the water demand amount, the conserve water resource;
2, simple in structure, fabricating cost is little, and is easy for installation.
The present invention is applicable to and fields such as floor water supply, building site water supply.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is support frame structure schematic representation of the present invention.
Among the figure: 1, sleeve, 2, the piston sheet, 3, spring, 4, slotted eye, 5, supporting frame, 6, osculum, 7, piston rod.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, a kind of pressure regulation unsteady flow water economizer, comprise the groove cover, piston and spring 3, the groove cover is cylindrical shell, in the groove cover piston is installed, the groove cover comprises sleeve 1 and supporting frame 5, sleeve 1 one ends are through hole, the other end is provided with the supporting frame 5 of taking water hole 6 out of, supporting frame 5 centers are through hole, sleeve 1 sidewall is provided with some slotted eyes 4, piston comprises piston sheet 2 and piston rod 7, piston sheet 2 is divided in two parts slotted eye 4, piston sheet 2 is slidingly matched with sleeve 1 inwall junction plane, piston rod 7 is slidingly matched with supporting frame 5 endoporus junction planes, piston can slide relatively with the groove cover, spring 3 is sleeved on the piston rod 7 between piston sheet 2 and the supporting frame 5, and spring 3 two ends contact with the end face of piston sheet 2 and supporting frame 5 respectively and link to each other, and with piston rod 7 afterbodys of supporting frame 5 fits limit stoper is installed, slotted eye 4 cross sections are V-type or wedge shape, slotted eye 4 quantity are 2-4, and osculum 6 evenly distributes on supporting frame 5, and osculum 6 quantity are 2-4, when water economizer is in off working state, be positioned at the long-pending 1%-5% that accounts for slotted eye 4 total sectional areas of slotted eye partial cross section of feed-water end piston sheet 2 one sides, groove sleeve wall thickness 1-2.5cm, sleeve 1 outer wall is equipped with some seal rings.
When the waterexit end is non-when using water state, piston and compression spring are in off working state, and the sectional area that is positioned at feed-water end piston sheet one side channel hole this moment is about the 1%-5% of total sectional area, keeps the pressure balance between feed-water end and the waterexit end.When the waterexit end is when using water state, feed-water end pressure is greater than waterexit end pressure, the piston sheet is subjected to the effect of feed-water end pressure, makes spring compressed, and the piston sheet moves to the waterexit end direction, its amount of movement and the change in direct ratio of water inlet and outlet end pressure difference, slotted eye water flowing sectional area is direct proportaion change thereupon also, uses Pascal's dynamic balance principle, keeps discharge pressure in normal range (NR), flow changes with changes in demand, realizes pressure regulation unsteady flow function.
When pressure regulation unsteady flow water economizer supplies water with water saving in the balance that is used for high-rise building, solved that the 1st～4 floor causes water waste greatly because of pressure of supply water in the building, for a short time cause the problem of insufficient water more than the 5-6 layer because of pressure, water source and pressure source loss have been carried out effective improvement.After testing, general pressure than common way of supplying water water saving about 20%, has improved the problem of high-rise building hydraulic pressure deficiency simultaneously about 0.1Mpa.This water economizer is the type of secretly putting in the pipe, and critical piece can adopt polyvinyl chloride plastic material to make, and cost is low.During installation, take former floor pipeline main valve or other inlet valve apart, water economizer integral body is put into valve front-end pipelines back recovery pipeline original state get final product.
