Description

Two hydraulic pressure type changes in temperature water tap

Technical field

The utility model relates to a kind of employing floating plug, utilize the inner pipe water pressure difference to open and close, the two water tap of changes in temperature water can be provided easily and effectively, belong to the valve class.

Background technique

At present, popular and by the widely used cold and hot duplex water tap of user on market, what mostly adopt is ceramic core, and a spot of ball valve combination product is also arranged.Though this series products is adopted in a large number, screw rod spinning mode more originally also has very much progress, but still exist some structural defectives, at first be that the product link is too much, complex structure, the mechanical axis core drives opening/shutting mode, making product open and close parts weares and teares and the shortening in working life easily, measured this series products of matter is often because of adopting high-grade high-abrasive material and porcelain core, the cost costliness, on the high side, can not reach the purpose of economy and durability.Even and product cost is very high, the impurity that also can't avoid the inner structure complexity that the pipe network of water quality inferiority or area are caused moves to decrease and destroys and can't avoid, and some tap is often promptly damaged soon by dress, is placed in an awkward position.This series products exposes sooner as adopting low-grade common material to make then structural defect, and its mechanical fastener usually is unable to undergo the wearing and tearing of mandatory switch motion and scraps and cause waste.The special heatproof of hot water service requires then more material to be proposed the demand of quality assurance, so all this series products, when solving cold and hot tap, more face difficulty, should satisfy the heatproof requirement, solve the quality assurance of structural member again, then can only seek reliability of material, and product so cost are increased, and can't guarantee serviceability.

So the said goods can't accomplish both to have saved cost, reliable in quality and the requirement that can conveniently use again.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of floating plug that adopts to utilize the two hydraulic pressure type changes in temperature water tap of hydraulic pressure opening/shutting mode supply changes in temperature water.

The purpose of this utility model is achieved through the following technical solutions: which comprises at least two hydraulic pressure induced type single valves that structure is identical, the valve body water outlet of described two single valves is connected by a three-way connector, and is connected with a water outlet link on this three-way connector.

Described single valve is mainly by valve body, spool, valve rod, draw seat, draw forming, the lower seal that spool is installed by its underpart can be pressed on the valve seat in the valve pocket, and valve rod top is connected with draws handle, the valve stem packing ring that draws on the seat is passed at the middle part of valve rod, and its lower end valve plug can be pressed on the middle through hole of spool.

Described spool upper end is provided with seal ring, and seal ring matches valve plug with being somebody's turn to do upward.

What described valve rod top joined draws being nested with on drawing seat, draw the surface of seat is provided with grooved tracks, with draw a convex position to cooperate to move to form rail mounted, driving valve rod induces spool to realize the action that opens and closes, and carry out the control of flow size at the pilot process of orbital motion, also reach the effect of temperature control simultaneously.

The left and right sides of the present utility model single valve is separate operation, when cold valves is opened, threeway in the middle of cold water enters, and water valve is when opening, hot water enters threeway, hot and cold water mixes back guiding water outlet and overflows, and the control of its water temperature is left and right sides hot and cold water switch's adjusting, but free adjustment arrives optimum water temperature for use.

The utility model compared with prior art, have serviceability strong, be not afraid of simple and direct reasonable, easy to operate, the characteristics such as temperature control is reliable and stable, Flow-rate adjustment is comfortable, and long service life, scope are wide of impurity, inner structure, be a kind of reliable two duplex changes in temperature tap.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

To do detailed explanation to the utility model by accompanying drawing below:

Shown in Figure 1, the utility model mainly comprise by: seal 4 on left valve barrel 1, left spool 2, left spool lower seal 3, the left spool, left valve rod 5, Zola seat 6, left valve stem packing ring 7 and Zola 8, on the three-way connector 9, water outlet link 10, right valve barrel 11, right spool 12, right spool lower seal 13, right spool seal ring 14, right valve rod 15, the right side draw seat 16, the right side draw 17, right valve stem packing ring 18, right water intake 19, left water outlet 20, right water outlet 21 and left water intake 22.

The utility model includes two hydraulic pressure induced type single valves that structure is identical at least, and valve body 1,11 water outlets 20,21 of described two single valves are connected by a three-way connector 9, and are connected with a water outlet link 10 on this three-way connector 9.

Described single valve is mainly by valve body 1,11, spool 2,12, valve rod 5,15, draw the seat 6,16, draw 8,17 compositions, on the valve seat that the lower seal 3,13 that spool 2,12 is installed by its underpart can be pressed in the valve pocket, valve rod 5,15 tops are connected with draws 8,17, the valve stem packing ring 7,18 that draws on the handle seat 6,16 is passed at the middle part of valve rod 5,15, and its lower end valve plug can be pressed on the through hole of spool 2,12 centres.

Described spool 2,12 upper ends are provided with seal ring 4,14, and seal ring 4,14 matches valve plug with being somebody's turn to do upward.

Described valve rod 5,15 tops join draws and is nested with 8,17 on drawing seat 6,16, draws the surface of seat is provided with grooved tracks, moves with drawing 8,17 convex positions are cooperated with the formation rail mounted.

The utility model is owing to adopt spool 2 and spool 12 utilizes hydraulic pressure to open and close, and that has avoided spool moves damage relatively, and in the anti-well sealing impurity to the damage of spool and Sealing.With the left valve barrel is example, when valve rod 5 by drawing when drive promoting 8, the sharp valve plug of valve rod 5 bottoms leaves the through hole in the middle of spool 2 upper sealing gaskets 4, spool 2 upper pressure reduce, bottom pressure increases, and according to hydraulic pressure and buoyancy spool 2 is held up, when arriving in the valve body 11 top of chamber, 2 of spools suspend in water, and the flow size is regulated and control with the high and low position of spool 2.Valve rod 5 upper ends then are connected 8 bosoms in drawing, so draw the motion of 8 mobile drive being leaned on valve rod 5, draw and then move 8 on drawing the tubing string of seat 6.And draw the centre of seat 6 is provided with valve stem packing ring 7, seal ring 7 is squeezed in and draws seat 6 inwalls, realizes top seal, and valve rod 5 then slides in the middle of valve stem packing ring 7.Be the extruding shape, so valve rod 5 can free sliding, again can be water-tight.Draw seat 6 and valve body 1 are connected, form complete valve pocket.After spool 2 was opened, water imported three-way connector 9 by water outlet 20, and three-way connector 9 is connected with water outlet link 10, and hot and cold water is all derived from water outlet link 10.The on-off principle of right valve is consistent with left valve, nothing but by the be connected position that determine hot water or cold water switch valve of when dress hot water or cold water's import with the hot and cold water supply tube, and it is general according to drawing 8 and draw indigo plant, the red hot and cold water sign of setting on 17 are installed, and corresponding.And the material of water valve adopts corresponding heat-resistance type material to make.
