Abstract

The utility model relates to a depressed self closing water-saving tap for a public water supply line and a civil water supply line, which is composed of a valve body 1, a valve ball 2, a sealing cushion ring 3, a sealing press cap 4 for a valve rod, a valve rod 5, a locking pin 6, a nylon rope 7 and a button 8. The utility model can realize self closing and can keep a normal closing state through water supplying pressure for avoiding phenomenon that water often flows or the water leaks and for achieving the purpose of effectively saving water. The utility model which is provided with few bearing sealing pieces has the advantages of novel structure, flexible on-off, simple and compact structure, no easy leakage, easy manufacture and repair, low cost, etc.

Description

Depressed self-cut off water-saving tap

The utility model relates to a kind of self-closing water saving water nozzle of push type public and the domestic water supply pipeline that is used for.

The tap water water nozzle is extensive use of rotation hand wheel (or handle) formula for a long time, and this kind water nozzle pressure bearing and seal easily damaged parts is many, easily leaks, so maintenance load is big, again because of its with manual rotation hand wheel (or handle) switch, not only convenient inadequately, and often metal run out and cause waste because of forgetting the pass after opening.Under current economic height prosperity both at home and abroad, productive life water growing tension situation, problem of water saving had become one of the most urgent heat subject already.At present, the novel water nozzles such as constant current self-closing water tap, anhydrous automatic turn-off water tap in limited time of domestic appearance produce in order to solve above-mentioned problem just.Though these water nozzles can reach the water saving purpose to some extent, common shortcoming then is that member is more; The structure more complicated, thereby make comparatively difficulty, and cost is higher.

The purpose of this utility model provides the self-closing water saving water nozzle of a kind of novel push type, utilize it to make things convenient for and realization water saving effectively, and it is simple in structure, is easy to manufacturing, and cost is lower.

The utility model is to realize like this.It is made up of valve body 1, valve ball 2, seal washer 3, valve stem seal pressure cap 4, valve rod 5, safetied pin 6, nylon rope 7, button 8.During assembling, earlier valve rod 5 one ends are stretched out from the insertion of valve body 1 entry end and from valve body 1 the place ahead valve rod eyelet; Successively seal washer 3 and pressure cap 4 are enclosed within valve rod 5 external parts, tightening also by screw thread pressure cap 4 and valve body 1, packing washer 3 is adjacent to valve body 1; Knob 8 is contained in valve rod 5 external parts by screw thread; Nylon rope 7 one ends are fastened on the annulus of safetied pin 6, and the other end is enclosed within on the valve rod 5; With valve ball 2 in valve body 1 entry end is packed valve body 1 into.Valve body of the present utility model 1 entry end that above-mentioned assembling is finished is installed on the tap water pipeline by screw thread, can come into operation.This kind water nozzle is a Normally closed type, opens with finger pressure, passes through water pressure self-closing.Under the normal condition, it is normally closed that valve ball 2 is come water pressure and valve body 1 valve seat location closely to contact realization; When the needs water, as long as gently press button 8 with thumb, valve rod 5 just promotes valve ball 2 and lifts off a seat, but water nozzle promptly is the opening state normal water supply; If think that long-time water maybe needs finger is left knob 8, then the eyelet that safetied pin 6 can be inserted on seal pressure caps 4, the valve rod 5 pins valve rod, when stopping water, opens or extract safetied pin with openhanded, then come water pressure to promote valve ball 2 again and be pressed on the valve seat, water nozzle is promptly closed automatically.

The utility model novel structure, switch is flexible, is used to water pressure and can realizes closing automatically and keeping normally off, thereby can avoid the running water or the phenomenon of metalling run out, and reaches effective water saving purpose.This kind water nozzle also has simple and compact for structure, and pressure bearing and seal spare is few, is difficult for leakage, is easy to manufacturing, maintenance and low cost and other advantages, is suitable for and applies.

Fig. 1 is a general structure schematic representation of the present utility model.

Fig. 2 is valve body 1 structural representation.

Fig. 3 (a) and (b), (c), (d) are respectively valve stem seal pressure cap 4, safetied pin 6, valve rod 5 and button 8 structural representations.

Below in conjunction with accompanying drawing enforcement of the present utility model is described further.

Valve body 1 of the present utility model is horizontal (see figure 2), its water intake, water outlet and conventional water nozzle are similar, institute's difference is that its substantially horizontal has one in order to the threaded M12 circular groove of sealing filler ring, valve stem seal pressure cap with in order to φ 7 eyelets of the valve rod of packing into along water intake center line front portion, its valve chamber water-in and water-out intermediate location is processed into can close-fitting sealing surface (valve seat) with valve ball, and material is brass or cast iron; The nontoxic nylon of valve ball 2 usefulness is made, diameter is decided according to coming the water pipeline diameter, can be made into series product, need guarantee during adapted that its diameter is greater than coming water pipe (pin thread) internal diameter, and less than valve inleting water mouth (box) internal diameter, to guarantee valve ball not only can pack into valve chamber but also unlikely fleeing from; Seal washer 3 is the zero shape circle that nontoxic rubber is made; Valve stem seal pressure cap 4 is hollow, internal diameter 7mm, and pressure cap one end band one φ 2.5 upright openings (inserting safetied pin uses), the other end band M12 pin thread (matching) with the circular groove box of valve body 1 front portion, material is brass or cast iron; Valve rod 5 usefulness brass or stainless steel are made, diameter 6mm, and one end band disc step, the other end band pin thread is drilled with 3 φ, 2.5 vertical eyelets (latch nail 6 usefulness) on it; The common steel or stainless steel of lock screw 6 usefulness is made, diameter＜2mm, and an end is made annulus, the other end band point; Button 8 usefulness brass or stainless steel are made, and there is the M6 eyelet (matching with the valve rod external part) of a band box at its middle part.Be further simplified structure, the convenient use, the utility model can be cancelled locking nail 6 and nylon rope 7; Simultaneously valve stem seal pressure cap 4, valve rod 5 also can corresponding cancellation the vertical eyelet of latch nail on it.But finger pressing button and can not unclamping all the time during this kind simplified structure type water nozzle water.
