Abstract
The utility model discloses a pedal self closing water stop valve. A valve core elevating regulating mechanism is composed of a pedal 1, an adjustable push cap 2, a push rod 3, a valve core 4, a pressure spring 5 for the valve core, wherein, the push rod is embedded and connected with a flexible sealing sleeve 6, and the sealing wing edge 7 of the flexible sealing sleeve 6 is pressed and fixedly connected with a valve body. The tightness of the utility model is good, the operation is convenient, when the utility model is trodden by a foot, the utility model is opened; when the foot is withdrawn, the utility model is closed. The utility model is especially suitable for the public washing device, and can also be used for the flushing device of the toilet of the washroom.
Description
The utility model belongs to valve, and especially daily normal pressure valve is made the field.
Present civilian running water valve adopts spiral water valve mostly, and is hand switch.Not only cause sealing surface wear to leak easily, and in some public use occasions, as public hygiene valve, public washing one's hands, because valve handle is that many people use jointly with valve, lavatory flushing urinal valve etc., pollute, easily spread disease germs, use both inconvenient, unhygienic again, thereby the somebody is for avoiding the valve infection of carrying disease germs, often be not related to after the water, cause valve often to open, waste water resource.
The purpose of this utility model is a kind of water valve of design, open with foot-operated mode, and have easy to use, health, anti-leak, people from i.e. pass, energy-conservation function.
The purpose of this utility model is to realize by following design.
Foot-operated Self-closed water valve constitutes can regulate spool elevator mechanism by pedal, adjustable top cap, push rod, spool, spool stage clip; Push rod and the flexible sealing connection that is nested, the sealing wing of flexible gland is along connecting firmly with the valve body press seal.
After having adopted design as above, the user is with riding moving pedal, and hatband moving top board in can regulate top backs down spool, obtains the water supply; With after finishing, pin leaves pedal, and the spool release of pressure resets under the effect of spool stage clip, makes valve closing, the water route disconnected every.Because with foot-operated, rather than use the manual operating valve, and avoid hand to touch valve body and easily caused germina infection, be particluarly suitable for using in the water supply, washing device of various public arenas, certainly, the utility model also can be used on toilet urinal equipment and other similar devices.
Description of drawings is as follows.
Fig. 1 is the utility model embodiment's a structure sectional view.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Can see that in Fig. 1 the utility model is in the situation when opening, and constitutes can regulate valve core elevator mechanism by pedal 1, adjustable top cap 2, push rod 3, spool 4, spool stage clip 5.Pedal is installed on the underframe 10, and 11 is that padal stop, 12 is that pedal Returnning spring, 13 is the pedal rotation pivot.Depress pedal, from valve port, current are along direction of arrow inflow and outflow with the spool top for adjustable top cap.Adjustable top cap 2 on the bolt of pedal, plays two aspect effects by scyewed joint: the one, and push push rod water valve is opened; The 2nd, can adjust water yield size according to different purposes, regulate assemblage gap, regulate the effect of wearing clearance.The ball cambered surface of top crown end is at various opening angles, all makes top cap and push rod keep the smooth gradual change that contacts and make water flow in opening process of maximum area.Push rod 3 connects with flexible gland 6 embeddings, that is flexible gland 6 is pressed on the ring gender gap groove on the top board 3, the sealing wing of stuffing box gland 6 along 7 by protruding circle 9 press seals on the lower spiro cover 8 that is screwed on the valve body on valve body, guaranteed the anti-overflow sealing of valve body.
For making valve port have more good adaptation, valve port 14 of the present utility model adopts cone structure, and spool 4 is covered with rubber sleeve 15 with the driving fit portion of valve port.
Adopt basic structure of the present utility model, when implementing, can make various schemes, can be used for multiple different use occasion after being equipped with different turnover water pipe, be not limited in scheme that present embodiment is given.
