Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary mixing valve, in particular a sanitary mixing valve with a colored valve body housing a valve control element.

[Conventional technology]

Mixing valves of this type with colored valve bodies have been known for some time and are especially installed in bathrooms and kitchens. Generally, the valve body is made of brass.
having a metallic or non-metallic surface. If the valve body is to be colored in a different color, the valve body is coated with a lacquer and, if desired, protected with a layer of transparent synthetic resin or baked powder coated.

The disadvantages of this type of traditional valve are that the metal or non-metallic surface is vulnerable to detergents or scratches, and brass is a good conductor of heat, so it is subject to large temperature changes and is sensitive to touch by the user. It's to the point where I feel uncomfortable. Furthermore, it is difficult to provide decorations, ornaments, marks, etc. on the surface from the point of view of the manufacturing process. When a chrome-plated valve body becomes damaged, it is either completely irreplaceable or very costly to replace.

[Problem to be solved by the invention]

The object of the present invention is to eliminate the above-mentioned drawbacks, and
To provide a mixing valve that is simple to manufacture, highly reliable in operation, and easy to assemble and repair.

[Means to solve the problem]

The problem is that a connecting member in the form of an approximately cylindrical inner housing is fixed to the sanitary appliance or to the wall;
and a base part, the base part having a water reactor therein, and a unit-shaped valve body in the form of an outer housing made of ceramic material and removably mounted over the connecting member, and having a valve control element. It is attached to the base part of the connecting member, and a plurality of collar-shaped steps are formed on the outer peripheral surface of the connecting member, and the diameters of the steps are different, and the diameter of the step closer to the base part is larger, The solution is that each step has an axial seal attached to it, which seal contacts the inner surface of the valve body and creates a watertight seal between the valve body and the coupling member.

The valve body is removably and therefore replaceably attached to the coupling member. The connecting member and the valve body are watertightly connected to each other by a seal inserted between them. The connecting member has a water supply channel that can be connected to a water supply system and can be fixed to a sanitary device or to a wall.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the accompanying figure, an embodiment of the invention of a single-lever mixing valve for a washbasin is shown in longitudinal section.

In the figure, 1 is the valve body. The valve body is made of porcelain and has a smooth surface. Valve body 1
is connected to the connecting member 2 therein. This connecting member is in the form of a sleeve-like brass inner housing with a connecting pipe 3 for hot or cold water. The connecting pipe 3 is fixed to the base portion 4 and connected to a water supply waterway (not shown). A cartridge 5 with a valve control element is arranged on the base part 4. The valve control element has a seal. The connecting member 2 is provided with two collar-shaped steps 6, 6' on its outer periphery. The lower step 6' has a larger diameter than the upper step 6. The role of the steps 6, 6' is to hold an axial seal 7 in the form of an O-ring, which interacts with a corresponding step 8, 8' formed on the inner surface of the valve body 1. to create a watertight seal.

Cartridge 5 is positioned by pin 9. Cartridge 5 is a threaded brass ring 10
This ring is held at the upper end of the connecting member 2. A threaded ring 11 made of synthetic resin is provided within the connecting member.
This ring 11 has an outer collar 12 which engages the upper end of the valve body 1 and positions it. Between the cartridge 5 and the connecting member 2,
An O-ring 13 is provided.

The valve body 1 is an integral part (unit-shaped part) and is easily replaceable. The valve body 1 can be mounted over a connecting member 2 that can be attached in advance. The connecting member is fixed via a threaded stud 15 and a lower seal 14 to a fixture support (not shown) of the sink.

The handle lever 16 has a support 17 . This support is connected to the upper end of the control lever 18. The control lever 18 is connected to the support 17 by a spring 20 held by a screw 19. The lower end of the control lever 18 is connected to the cartridge 5
It interacts with a disc-shaped control element (not shown) in the . Water flows from the cartridge through opening 21 to outlet 22. The front end of the outlet is fitted with a jet operating part 23 to prevent the build-up of high internal pressure that can occur when the nozzle for mixing water and air is blocked.
It is equipped with

The valve according to the invention is easy to assemble and repair. During assembly, the connecting member 2 is first fixed to the washstand. Then, the valve body 1 is fitted onto the connecting member 2 via the seal 7. The valve body 1 and the connecting member 2 are fixed to each other by a threaded synthetic resin ring 11. The type of seal and the construction of the valve body 1 and the connecting member 2 ensure that no tolerance problems arise between the two different materials, namely ceramic and brass.

The illustrated structure above is only one embodiment of the present invention. The invention is not limited to this example. Changes may be made within the scope of the basic idea of the invention, in particular with respect to the arrangement and shape of the components. for example,
A radial seal with a lip can be provided between the coupling member and the valve body.

The valve according to the invention is easy to manufacture. The cost is relatively low. Ceramic valve bodies, which are less thermally conductive than metals and therefore have less unpleasant operating temperatures, can be easily formed into the desired color and shape;
In addition, desired decorations, ornaments, marks, etc. can be provided. Furthermore, the surface of the valve body can be made into a polished surface to correspond to the surfaces of colored sinks, washstands, bidets, etc. There is no risk of calcification here. The surface of the valve body is also detergent and scratch resistant.

[Effects of the Invention] Since the valve body of the sanitary mixing valve of the present invention is made of ceramic material, it is resistant to detergents and scratches, and it is less conductive of heat than metal, so it feels cold to the touch. Never feel uncomfortable. Furthermore, the surface of the valve body can be a polished surface, easily formed into the desired color and shape, and can be provided with decorations, ornaments, markings, etc. If this valve body, which is generally made of brittle ceramics, is used as a strength member, it may be damaged. Therefore, in the present invention, the connecting member is fixed to sanitary equipment or a wall, and the valve body is mounted by covering the connecting member. did. Furthermore, since the diameter of the step on the outer peripheral surface of the connecting member becomes smaller toward the lower base portion, the valve body attached to the connecting member can be easily removed. It is easy to replace and repair the functional parts of the valve. Furthermore, although the valve body is easily removable in this way, it is not possible to provide a watertight seal between the valve body and the connecting member by means of an axial seal provided at the stepped portion of the connecting member. be.
