Embodiment 1: referring to Fig. 1, Fig. 4, Fig. 5 and Fig. 6, the Protective valve of cutting off the water is made of ammonium button, spool, valve body and damping four parts, wherein: (a) button part is made up of button (1), Returnning spring (2), connecting sleeve (3), sealing gasket (4), O-ring seals (5) and push rod (6), establish Returnning spring (2) between button (1) and the connecting sleeve (3), O-ring seals (5) is located between connecting sleeve (3) and the push rod (6), between push rod (6) and the connecting sleeve (3) is Spielpassung, connecting sleeve (3) is threaded with valve seat (20), with sealing gasket (4) sealing; (b) the spool part is made up of platen (7), nut (8), pressure spring (9), valve pocket (10) and valve rod (11), platen (7) and nut (8) are threaded or are riveted on the top of valve rod (11), if just cancel nut (8) with riveted joint, valve rod (11) below installing valve pocket (10), pressure spring acts between platen (7) and the valve pocket (10), and valve pocket (10) and valve rod (11), valve body are more loose Spielpassung between (16); (c) valve body part is by shutoff (12), valve gap (13), micromesentery (14), form closing screw (15) and (19), valve body (16), block (17), seal dissepiment (18) and valve seat (20), between shutoff (12) and the valve gap (13) is interference fit, folder is established micromesentery (14) between valve gap (13) and the valve body (16), and with connecting closing screw (15), block (17) embeds the center portion of seal dissepiment (18), folder is established seal dissepiment (18) between valve body (16) and the valve seat (20), and with connecting closing screw (19); (d) damping portion is an installing damping cover (21) in valve seat (20).
Embodiment 2: referring to Fig. 2; often not high at pipeline hydraulic pressure; in the area or tall building that water flow is very little; the damping portion of Protective valve of cutting off the water can adopt by spool (22); little spring (23); the adaptive damping that little valve seat (24) and sealing gasket (25) are formed; wherein little spring (23) acts between spool (22) and the little valve seat (24); and spool (22) is pressed together on the valve seat (20); have an aperture on the spool (22); its effect is when cutting off the water; after seal dissepiment (18) is closed; prevent to produce pressure at seal dissepiment (18) epicoele because of spool (22) is closed; avoid this pressure to reduce to seal impacting force; little valve seat (24) and valve seat (20) are for being threaded, with sealing gasket (25) sealing.
Embodiment 3: referring to Fig. 3, for adapting to the industry needs, the button part of the Protective valve of cutting off the water can change electronic control into, with the button cancellation, and installing low pressure wet type electromagnet, this electromagnet is a prior art, the equal production and sales in each special manufacturer.
The fixing damping working principle of Protective valve of cutting off the water:
Cut off the water Protective valve in pressure spring (9) effect down, seal dissepiment (18) is pressed to the sealed mouth of valve seat (20), valve is in closed condition at this moment.When tap water flows to when cutting off the water Protective valve, a current part enters valve seat (20), and another part enters the barrier film cavity of resorption through the control aperture.When pressing hand push button (1), push rod (6) is with seal dissepiment (18) jack-up, and current enter seal dissepiment (18) epicoele through sealed mouth, outside water outlet flows out valve, enters water tap then.Because the throttling action of water outlet place damping cover (21), make the seal dissepiment epicoele produce certain back pressure, again because the effective work area of seal dissepiment (18) epicoele much larger than the effective work area of micromesentery (14) cavity of resorption, so the upward force Fa sum that counterpressure Fb is subjected to hydraulic pressure greater than upward force Ft and micromesentery (14) by spring (9) generation, i.e. Fb＞Ft+Fa.This moment, hydraulic pressure was just pressed to valve body with seal dissepiment (18), and water intake communicates with water outlet, but tap water normal flow mistake.When cutting off the water, the pressure of seal dissepiment (18) epicoele disappears thereupon, and seal dissepiment (18) is pressed to sealed mouth rapidly under the effect of pressure spring (9), valve cuts out.When coming water once more, this valve is in closed condition all the time under pressure spring (9) effect, and micromesentery (14) cavity of resorption produces thrust upwards under the effect of hydraulic pressure in addition, and this power also acts on the seal dissepiment (18) through valve rod (11) and platen (7).Because the cross-sectional flow area that the effective work area of micromesentery (14) is a bit larger tham sealed mouth, impacting force Fa's makes a concerted effort greater than the jack-up power Fs of sealed mouth hydraulic pressure so spring force Ft and micromesentery make progress, that is: Ft+Fa＞Fs makes sealing force with the increasing and increase of hydraulic pressure, and is reliable to guarantee sealingly secure.Fixedly damping is cut off the water the pressure loss of Protective valve less than 0.03MPa (3 meter water column), and it can be at the throttle down rapidly of cutting off the water in back 0.3 second.
The working principle of adaptive damping be on the back pressure valve spool (22) in little spring (23) effect down, make seal dissepiment (18) epicoele produce the force value (0.02MPa) of an approximate constant, seal dissepiment (18) is lifted, the proper functioning of assurance valve.The adaptive damping Protective valve pressure loss 0.02MPa that cuts off the water.
The utlity model has following advantage: simple and reasonable, easy to install, volume Little, in light weight. The characteristics of protective valve are that tap can normal worker when water is arranged for running water owing to cut off the water Do, valve autoshutdown when cutting off the water cuts off path, and valve still is in closed condition when again coming water, After only pressing button, water-stop valve just can be switched on, and tap recovers normal operation, thereby can Lean on, effectively prevented the waste of water resource.
