Abstract
The utility model provides a plug cock type cold water tap, which is composed of a handle, a valve rod, a valve body and a sealing sleeve, wherein, the lower part of the valve rod is arranged on the sealing sleeve, and the sealing sleeve and an inner cavity of the valve body are integrally connected. Water passing holes which are matched a water inlet and a water outlet of the valve body are arranged on the lower part of the valve rod and the sealing sleeve. The water tap is directly controlled to be opened and closed by the rotation of the valve rod. The utility model has the advantages of good tightness, quick opening, small abrasion, long service life, simple structure and low cost.
Description
The utility model relates to a kind of cold water tap, particularly a kind of special valve that is installed on the water supply pipe as the usefulness that discharges water.
The common cold water tap of Chu Shouing generally is to adopt the screw thread transmission between valve rod and the valve gap to drive the valve rod lifting on the market, reaches the purpose of switch tap water, not only open, close slowly, and thread abrasion is fast, thereby shortened the working life of water nozzle.By my quick open type cold water tap (application number 99241709.0) in application on November 30th, 1999, this kind water nozzle drives upper valve rod by handle, make axially motion in the pilot hole of lower valve rod in valve gap, thereby drive the sealing flap open or close water nozzle have open quick, sensitive, it is little to wear and tear, change advantage easily, but owing to be the stretching, extension by the sealing flap or shrink and to reach closing or opening of water nozzle, thus as the flexible fatigue of the rubber flap of Sealing to certain influence is arranged in working life of water nozzle.Ball-type water nozzle (application number 85203603) by comrade's Liu Guangxing application, be that the spheroid that there is the water port at a middle part is set in valve body, the stem lower portion that is connected with handle is designed to cuboid shape, and insert in the cuboid groove of spheroid, drive spheroid by valve rod and rotate the purpose that reaches open and close, solve thread abrasion and the frequent problem of changing packing ring that existing water nozzle exists, prolonged the working life of water nozzle.But the cooperation place of this kind water nozzle valve rod and spheroid still exists wear problems, can reduce the degree of flexibility of water nozzle open and close after use a period of time, and this kind water nozzle also exists complex structure, the defective that cost is higher.
The purpose of this utility model is to provide a kind of cock-type cold water tap, and this kind water nozzle rotates directly control opening and closing by valve rod, with reach good airproof performance, little, the long service life of opening fast, wear and tear, simple in structure, purpose that cost is low.
Solution of the present utility model is that the cock-type cold water tap comprises handle, valve rod, valve body, stuffing box gland, it is characterized in that stuffing box gland is arranged in the valve body chamber and with valve body fuses, stem lower portion is arranged in the stuffing box gland, on stem lower portion and stuffing box gland, be equipped with the water passage hole that cooperates with valve inleting water hole and osculum, be connected with key by screw thread between valve rod top and the handle.
Above-mentioned water passage hole can be a clear opening, also can be the angle through hole.
Above-mentioned valve rod and stuffing box gland coaxality.
Advantage of the present utility model is that stem lower portion is provided with the water passage hole that cooperates into and out of the water hole with valve body, when handle drive valve rod rotates between 0～90 ° in stuffing box gland, the contract fully when vertical overlaps the maximum that reaches water nozzle to valve rod water passage hole axis and opens with valve body water-in and water-out axially bored line from valve rod water passage hole axis and valve body water-in and water-out axially bored line can to make water nozzle, have and open the advantage quick, sensitive, that flow velocity is fast, wearing and tearing are little, and can regulate flow easily.Because valve rod of the present utility model and stuffing box gland be in advance built in valve inner and coaxality, the quality of fit height, good seal performance has more effectively prolonged working life of water nozzle.The utility model only needs handle, valve rod, valve body and four critical pieces of stuffing box gland to be assembled, and simple and reasonable, cost is low, and is easily manufactured.
Accompanying drawing 1 is the utility model straight-through type closed condition structural drawing.
Accompanying drawing 2 is the utility model straight-through type opening state structural drawing.
Accompanying drawing 3 is the utility model angle general formula closed condition structural drawing.
Accompanying drawing 4 is the utility model angle general formula opening state structural drawing.
Below in conjunction with accompanying drawing the utility model embodiment is further described.
Embodiment one: with the straight-through type water nozzle is example, and the utility model is formed by combining by handle 4, the valve rod 3 that is connected with handle 4, valve body 1, the stuffing box gland 2 that cooperates with valve rod 3 bottoms that is arranged in the valve body 1.Actinal surface is provided with 90 degree limited steps in the valve body 1, and it directly connects into and out of the water hole coaxial line and with the mesopore die cavity, and diameter is 15mm.Handle 4 profiles are circular cone, upper end external diameter 22mm, and internal diameter 17mm, dark 6mm is used to place handle cover 6; Handle 4 middle parts are provided with the inner splined hole of diameter 12mm, and the number of teeth 38 cooperates with valve rod 3; Lower outer diameter 25mm, internal diameter 21mm, dark 6mm.The partly long 28mm of the spanner of handle 4, physical dimension is wide 11mm, thick 3.5mm, inner dimensions is wide 18mm, thick 7mm fuses with handle 4.Valve rod 3 is designed to cylindrical, top external diameter 12mm, and long 12mm is provided with long 6mm, and the number of teeth is 38 external splines, cooperates with the internal spline of handle 4, and is connected with handle 4 with screw 5 by this spline; Valve rod 3 lower outer diameter 17mm, long 16mm, thus between top and bottom, form a platform, move up to prevent valve rod 3; Have a long 10mm in valve rod 3 lower, transverse, the elliptical aperture of wide 8mm is as water passage hole.On valve body 1 mesopore die cavity wall, stuffing box gland 2 is set, closely cooperate with valve rod 3, on stuffing box gland 2, be respectively equipped with long 10mm corresponding to valve body 1 water-in and water-out hole site, the elliptical aperture of wide 8mm, and vertically be provided with four wide 2mm at stuffing box gland 2 cylindricals, the anti-skidding muscle of high 0.5mm tightly is embedded in the mesopore die cavity of valve body 1, to guarantee the reliability of sealing.
That the utility model stuffing box gland 2 adopts is wear-resisting, heatproof, corrosion-resistant, nontoxic composite seal, and valve body 1, valve rod 3, handle 4 all can adopt ABS or PVC injection molding, and outward appearance can be equipped with shades of colour or adopt the top layer plating to be coated with processing, and is very elegant in appearance.During making, earlier prefabricated stuffing box gland 2 is enclosed within on the valve rod 3,, valve body 1, valve rod 3, stuffing box gland 2 is formed contain sealing in company with the directly molding and forming of mold cavity that the inserts of valve body 1 is put into valve body 1, good seal performance, every cost is only about 0.5 yuan.
Embodiment two: with angle general formula water nozzle is example, the boundary dimension at valve rod 3 tops and middle part is consistent with the upper and lower of straight-through type water nozzle valve rod, and the lower diameter of angle general formula valve rod is 14mm, and long 4mm is vertically having diameter 10mm, the hole of dark 15mm, cooperate with valve body 1 water inlet, laterally have long 10mm, the elliptical aperture of wide 8mm, cooperate with valve body 1 osculum, this transverse holes is communicated with vertical hole.Corresponding to valve rod 3 paddle hole is set on stuffing box gland 2, the water nozzle remaining part is consistent with the straight-through type water nozzle.
The utility model valve body 1 two ends can be processed into internal thread and be connected with pipeline, use as valve.
