Abstract

The utility model relates to an improved cold-water nozzle, composed of a valve body, a valve core and a handle. The improved point mainly lies in that the valve core is upper and lower two chips made of wear resistant ceramics; the lower chip is provided with two radially symmetrical valve holes, and the upper chip is provided with a fin corresponding to the valve hole, so the quick opening and closing of the water nozzle can be realized through dialing the upper chip to make and break the lower chip. The utility model has beautiful appearance, low cost, labour-saving operation and no water leakage.

Description

Cold water tap

The utility model is a kind of improved cold water tap.

Cold water tap, that is cold water faucet, valve kind, known commercially available cold water tap adopt spiral spool mostly, change by rotatable handle and go up several circles, and be same, must turn round the same number of turns when closing, and has suspicion too slow unavoidably.

The purpose of this utility model provides a kind of improved cold water tap that can change up the pass soon.

The utility model is to realize like this, cold water tap, referring to accompanying drawing, it is by valve body (1), spool (3) and handle (10) are formed, spool (3) is positioned between the intake pipe (17) and outlet pipe (15) of valve body (1), improvements are that described spool (3) is two, one is following chip (14), one is last chip (13), wherein descend chip (14) to insert the middle location of groove (18) of valve body (1) by its groove bar (20), be lined with packing ring (2) between following chip (14) and the valve body (1), following chip (14) have warp-wise to two valve openings (21) of lining and down chip (14) lower end lead to intake pipe (17) pipe, the upper end is logical with outlet pipe (15) pipe, last chip (13) is folded mutually with following chip (14) concentric, last chip (13) be one with the warp-wise of valve opening (21) aperture of following chip (14) size coupling to serving as a contrast and the double fins of able to turn on or off valve opening (21) when valve body (1) inner chamber rotates, the inner chamber of valve body (1) top has the gland nut (11) that pipe with it connects, can be inserted in the above-mentioned gland nut (11) by the valve rod (6) that chip (13) are stirred in rotation, have groove (19) on the both wings of last chip (13) lining.The groove (19) of chip (13) has two shift forks that match (22) on the lower end correspondence of valve rod (6).Above-mentioned handle (10) has the bonnet (9) that can be placed on the gland nut (11), be equipped with seal ring (4) between bonnet (9) inwall lower edge and valve body (1) connecting place and the gland nut (11), the valve rod (6) of handle (10) by bonnet (9) and gland nut (11) inner chamber is affixed and can rotate freely the groove (19) that valve rod (6) stirs chip (13) through shift fork (22) chip (13) is pivoted with screw (7) screw thread.Because non-threaded socket between valve rod (6) and the gland nut (11), two wing center lines of last chip (13) open and close with the heavy orthogonal fork of two hole center line concentrics of following chip (14), chip in the event (13) descends chip (14) only to need to change 90 ° relatively, promptly only need turn handle (10) clockwise or counterclockwise half-twist can realize the totally-enclosed or full open of the fin of chip (13) to the valve opening of following chip (14), the effect that reaches instantaneous realization peak rate of flow or close rapidly, change up the pass soon, improve work efficiency more than ten times at least than known technology.

Be the accompanying drawing of a specific embodiment of the utility model below, wherein:

Fig. 1 is the structural representation of cold water tap;

Fig. 2 is the structural representation of following chip;

Fig. 3 is a structural representation of going up chip;

Fig. 4 is the structural representation of valve rod.

Among Fig. 1-4,1-valve body, 2-packing ring, 3-spool, 4-seal ring, 5-seal ring, 6-valve rod, 7-screw, 8-cover plate, 9-bonnet, 10-handle, 11-gland nut, 12-driving lever, 13-last chip, 14-following chip, 15-outlet pipe, 16-water outlet, 17-intake pipe, 18-groove, 19-groove, 20-groove bar, 21-valve opening, 22-shift fork.

Valve body among this embodiment (1) adopts engineering plastics to mould notes as shown in the figure and forms.Bonnet (9) is also moulded notes with the engineering plastics one with handle (10), the intake pipe (17) of valve body (1) is processed into shape of threads with general general conduit pipe joint size coupling and with tube wall, the downward end outwardly of outlet pipe (15) forms mouthful water outlet (16) through expansion, concentric is followed successively by the packing ring (2) of favorable sealing property from bottom to top in the valve pocket between intake pipe (17) and the outlet pipe (15), have groove bar (20) the following chip (14) that wear-resistant ceramic makes of drawing materials, the last chip (13) that has groove (19) with the wear-resistant ceramic making, by the driving lever (12) of its shift fork (22) insertion groove (19) to control chip (13), with on the valve rod (6) of driving lever (12) integral production and the lid valve body (1) that has a handle (10) and the valve rod (6) with the bonnet (9) of valve body (1) socket, wherein go up chip (14) and insert valve body (1) inwall bar groove location by its groove bar, has gland nut (11) between valve rod (6) and valve body (1) the valve pocket inwall, the seal ring (5) of two circle favorable sealing properties under the fit between gland nut (11) and the valve rod (6), be equipped with the seal ring (4) of favorable sealing property between the inwall lower edge of bonnet (9) and valve body (1) connecting place and the gland nut (11), because the layout of above-mentioned multi-layer sealing ring makes this water nozzle than the more leakproof of general water tap.Fixed with screw (7) between the top of above-mentioned valve rod (6) and the bonnet (9), the cover plate (8) that a bonding color is gazed on the top center step that on the screw (7) is bonnet (9), both can make this water nozzle more apparent attractive in appearance, can prevent that again screw (7) from arbitrarily being turned and influence the water nozzle overall structure.The cold water tap of the present utility model of Gou Chenging is respond well through sampling thus, reaches designing requirement fully, has to change up the pass soon, and moulding is lightly attractive in appearance, and is cheap, practical, corrosion-resistant, use advantage water-tight, rapid operation for a long time.
