Abstract

The utility model relates to a shower mixing valve with adjustable central distances and directions, which is composed of a handle, a valve body, a straight-tube-shaped screw sleeve connected and fixed with the valve body, an outer connecting tube bended at 90 DEG or less than 90 DEG, an assembly outer connecting screw on the upper end of the outer connecting tube and a corresponding fixing-sealing structure. The utility model is characterized in that the straight-tube-shaped screw sleeve which can be fixed on the valve body and the elbow-shaped outer connecting tube for cold and hot water have the adjustable central distances and directions, namely, outside connecting angles, directions or central distances can be realized by regulating or processing the outer connecting tube. Thus, the utility model with easy installation and high rate of finished products can reduce the manufacturing processes for the mixing valve, save materials, reduce costs of a single-handle or a dual-handle mixing valves, and can be extensively applied to showers or water heaters.

Description

Centre-to-centre spacing, the shower mixing valve that direction is adjustable

The utility model relates to a kind of centre-to-centre spacing, shower mixing valve that direction is adjustable.

Existing shower mixing valve (comprising two kinds of single handle and double-handles), as the homemade water heater of method with single handle water mixing valve, though with a handle is that alternative two turning handles carry out the function that hot and cold water mixes, made things convenient for the user, but square nipple spacing (centre-to-centre spacing) that links to each other with valve body and direction manufacture with frock on must strict guarantee.This is because valve body and square nipple are fixed into one, therefore more needs strict control on manufacturing process, also makes the mixing valve structure complexity, and consumptive material is many, and this certainly will cause the consumption power of taking a lot of work, and also is difficult to guarantee the high qualification rate of product.

The purpose of this utility model is to overcome above shortcoming, provides a kind of valve body and being connected of hot and cold water extension tube attached can guarantee centre-to-centre spacing, the shower mixing valve that direction is adjustable.

Another purpose of the present utility model is both to save material, and can guarantee that again the reasonable manufacturing process of high yield rate is implemented.

The utility model only needs to keep the tubular swivel nut of quarter bend of an orientation to be improved to the straight short tube shape of particular design to the need of prior art, extension tube attached with straight tube-like is designed to bend pipe again, the angle of bend pipe can be right angle or less than the right angle, this custom-designed swivel nut and extension tube attached, can be as required, make external connection angle, direction and centre-to-centre spacing only depend on the shape and size of extension tube attached neatly, and the design of mixing valve body, manufacturing process are all greatly simplified.

Provide specific embodiment of the utility model in detail below in conjunction with accompanying drawing.

Fig. 2. the utility model assembly left view.

Fig. 3. STRUCTURE DECOMPOSITION figure of the present utility model.

Fig. 4. the utility model simplified structure exploded view.

Fig. 5. the utility model simplified structure front view.

Fig. 6. dual-handle shower mixing valve assembly front view.Wherein: 1. valve body, 2. extension tube attached, 3. nut, 4. copper washer, 5. rubber washer, 6. swivel nut, 7.O shape circle, 8. outer connected nut, 9. handle of assembly, Z: running water inlet opening, C: cold water apopore (inlet water tank), H: hot water inlet hole, M: mixing water apopore.

Herein only be that example is drawn into and out of the water hole with the open-type water heater.

As Fig. 1, Fig. 3, shown in Figure 4, the utility model is by one or two hot and cold water regulating handle 9, the valve body 1 that spool and valve body constitute, be connected and fixed the straight tube shape swivel nut 6 of sealing with it, hot and cold water extension tube attached 2 is formed with the fixing seal structure that rubber washer 5 constitutes with the outer connected nut 8 of assembly with nut 3, copper washer 4.Above-mentioned swivel nut 6 is that the external screw thread on it is connected with the internal thread of valve body 1, and through 7 sealings (adding glue fixes) of O shape circle, the right side endoporus of this swivel nut 6 is a hexagon, for with inner hexagon spanner fixedly swivel nut on valve body, the circular hole in left side is slightly larger than the external diameter of extension tube attached 2, and extension tube attached 2 is inserted wherein can be along axes O O ₁Rotation (change direction) and enough installation strokes are to adapt to adjusting centre-to-centre spacing.Screw nut 3 via copper washer 4, compressing rubber packing ring 5 with extension tube attached 2 fixing seals in the endoporus of swivel nut 6.

Above-mentioned extension tube attached 2 is an end is connected the outer connected nut 8 of assembly of usefulness with shower bend pipes, and the bend pipe angle of this extension tube attached 2 can select to be equal to or less than 90 ° a certain angle (but be 90 ° of extension tube attached bendings or less than 90 °) as required.This structure has guaranteed that the centre-to-centre spacing of external connection angle of the present utility model, direction and hot water pipe installation only depends on the shape and size of extension tube attached 2, valve body 1 can independently be made, extension tube attached optionally cooperates flexibly and gets final product, as shown in Figure 6, the bending angle of extension tube attached is decided according to the centre-to-centre spacing in valve body horizontal length and shower hot and cold water adapter hole less than 90 °.Therefore can save the raw material (shortening length) of valve body, simplify the manufacturing process of valve body simultaneously.Both saved material like this, and can guarantee high yield rate again.And general extension tube attached adopts brass tube mostly, and bending technique is quite ripe.

As another embodiment of the present utility model, be that the profile that above-mentioned swivel nut 6 is designed to an end is a hexagonal nut, the other end is for having externally threaded swivel nut, its endoporus matches with extension tube attached 2, as Fig. 4, Fig. 5, and the screw-internal thread fit of this swivel nut 6 and valve body 1, extension tube attached 2 is directly inserted in the valve body 1 via swivel nut 6, copper washer 4, rubber washer 5, by screwing swivel nut 6, via copper washer 4, compressing rubber packing ring 5 and with extension tube attached 2 sealing and be fixed in the valve body 1.This reduced form the utility model has saved nut and O shape circle.

In sum, the utility model has the advantages that conspicuous, straight tube shape swivel nut combines bend pipe plug-in type hot and cold water extension tube attached and valve body dexterously, improved the existing locate mode that is threaded, make the external connection angle of shower or water heater, direction or centre-to-centre spacing are only realized by the adjusting or the design processing of extension tube attached, so not only make frock convenient, rapidly, and the design and the manufacturing process of mixing valve body have been simplified, the yield rate height, labor and material saving again, therefore single handle or double-handle water mixing valve are more added and attain, and be widely used on various showers and the water heater.
