Abstract
The utility model relates to a flushing valve for toilets, which is used for civil architectures. The existing flushing valve has the disadvantages of short service life and high cost caused by moving parts which are easy to abrade. The utility model adopts a main valve with a diaphragm and replaces the parts which are easy to abrade. Therefore, the utility model has the advantages of long service life, low cost and better sealing performance.
Description
The utility model is the urinal flushing valve that a kind of civil building already use.
Use of the urinal Rinsing unit that present civil building generally adopt pulls elevated tank more, and it is well-known there is many-sided shortcoming.Recently, advanced piston type hand occurred and removed flushing valve (FLUSH--VALVE), this flushing valve can be found from " hardware goods knowledge " book that in 1984 Science and Technology of Shanghai publishing houses publish, and the structure of this flushing valve is seen Figure of description 1.As seen from the figure, the main valve of this invention is that piston type is reciprocating, and its other parts wear and tear easily, thereby working life is short; In addition, the fitting surface of piston plays the seal isolation effect simultaneously, thereby relevant other the machining accuracy inevitable requirement of parts is higher, makes its cost and cost higher.
The invention, be to adopt barrier film (seeing accompanying drawing 2 part 13 in addition) to obtain reliable sealing (avoiding main water cavity 1 mutual string water between control water cavity 4), and cancelled piston, overcome the wear problem between the reciprocating part, thereby improved working life, reduce required precision, reduced manufacture cost.On structural design, done many successful improvement again, made the more convenient installation of the utility model.Conveniently use and help using water wisely.
Concrete structure of the present utility model and working principle are summarized as follows in conjunction with Figure of description 2:
This flushing valve is mainly by valve body (2). main valve (17). and diaphragm (13). control valve (8). safety check (16) is adjusted screw (7) port lid (6). gland (11) and handle formations such as (12).Wherein, part diaphragm (13) plays a part the position of restriction main valve (17) on the one hand in addition, utilizes it that main chamber (1) and control chamber (4) are separated on the other hand, to prevent the water crossfire.Main valve (17) is the core component of this flushing valve, its structure as shown in Figure 3: main chamber was provided with filter screen (21) before water intake, stop up flow channel to prevent foreign material; Main valve is provided with a safety check (16), and the effect of this safety check is no longer to flow back to main water cavity behind control water cavity water-filling, thereby guarantees that the hydraulic pressure in the control chamber can remain the maximum pressure at water source.Like this, both be cutting off the water of water source short time, the control water cavity maximum pressure that preceding water source once reached that still can keep cutting off the water.Thereby main valve can not be opened.This has just prevented the into running water pipe that flows backwards of the sewage in the urinal effectively; The sealing surface of main valve has been taked the sealing gasket (23) made with rubber in order to maintain better seal.
When flushing finish closed control valve (8) after, the time that main valve (17) is closed is by the flow capacity of control water cavity (4) and the water flow decision by water channel (18) and restriction (5), the diameter of water channel (18) and restriction (5) is what to have determined in making, and after making, for regulating the main valve shut-in time, have only the flow capacity of regulating control water cavity (4), this corrective action is born by adjusting screw (7).Both limited the stroke of main valve (17), thereby regulated water displacement and water discharge time by adjusting screw.
The working principle of the utility model ┈ diaphragm type urinal flushing valve is summarized as follows:
When valve is installed and after water flowing comes into operation, this moment, main water cavity (1) and control water cavity (4) all can be full of water, because the pressure of water is at the active area of the active area of controlling water cavity greater than main water valve, thereby main valve (17) has been pressed on the main valve seat (20), make flushing valve be in closed condition, and when source pressure big more, then main valve is closed tight more, therefore, the tightness degree that main valve is closed is self-regulating along with the size of source pressure, and these characteristics have guaranteed that this flushing valve is difficult for leaking.
When moving handle (12), having promoted control valve (8) moves and is opened, at this moment, water in the control water cavity (4) flows into drain opening (19) by bleeder line (14), makes the hydraulic pressure in the control water cavity (4) drop to zero, water pressure in main water cavity this moment (1) will promote main valve (17) and move, make main valve open, the water of water intake flows into drain opening (19) in a large number, has realized washing capacity.
When release handle (12), control valve (8) is closed by the active force of spring (10), and bleeder line (14) stops to discharge water, and the water of main water cavity (1) is by water channel (18).Safety check (16) and restriction (5) enter control water cavity (4) raises the pressure of control water cavity gradually, promotes main valve (17) at leisure and closes, and draining stops.
The orientation of the installation of this diaphragm type urinal flushing valve is unrestricted, no matter founds dress.Paperback or angle mount all can be worked; Its water displacement can utilize handle to regulate arbitrarily according to the needs of flushing, and this is very useful to using water wisely.
Preferred embodiment of the utility model:
Valve body casting forms, and material can be cylinder iron or cast copper, preferably uses cast copper, with anti-corrosion; The water intake diameter can be made into 15.20 or 25mm, and the drain opening diameter should be greater than water intake; The circulation diameter of main valve is consistent with entry port; The diameter of diaphragm (promptly controlling the diameter of water cavity) is 40--55mm, and diaphragm adopts rubber or nylon material to make; Control valve (8) circulation diameter is 8--10mm; Water channel (18) diameter is 1--2mm; Restriction (5) diameter is 0.5--1mm; Bleeder line (14) diameter is 2--5mm; Safety check (16) circulation diameter is 4--6mm.
Claims (5)
1, the urinal flushing valve already used of a kind of civil building is mainly by valve body.Control valve.Main valve, parts such as adjusting screw handles etc. in addition constitute, it is characterized in that it has a diaphragm type main valve (17), the effect of barrier film (13) is to limit the main valve position also main water cavity (1) and control water cavity (4) to be separated, thereby has obtained excellent sealing performance easily.
2, urinal flushing valve as claimed in claim 1 is characterized in that being provided with in the main valve safety check (16), be used for anti-sealing and flow back to main water cavity by control chamber, thereby the interior sewage of tight and urinal that has guaranteed main valve flows backwards.
3,, it is characterized in that being provided with filter screen (21) before the inlet of safety check (16) as claim 1,2 described urinal flushing valves.
4, urinal flushing valve as claimed in claim 1 is characterized in that the main valve sealing surface is provided with the sealing gasket made from rubber (23).
