Description

Description Ceramic cartridge tap with a structure preventing leaks

Technical area

The present invention belongs to the field of sanitary equipment and relates in particular to a ceramic cartridge valve with a structure preventing leaks.

Existing technologies

The faucet usually includes the bathroom faucet, the kitchen faucet, etc. It is composed of a tap body, a ceramic cartridge placed in the tap body, the transmission rod of this cartridge is connected to an articulated handle, an inlet pipe is connected to the inlet end of the cartridge, and an outlet pipe at the outlet end of the cartridge.

At present, even if the rotary outlet taps on the market have solved the problem relating to the change of direction of the water flow, after long-term use, the sealing ring wears out and thus causes water seepage.

BE2019 / 5569

Summary of the invention

The present invention aims to provide a ceramic cartridge valve with a structure preventing leaks, in order to solve the problem relating to water seepage caused by wear of the sealing ring. To achieve the above aim, the technical solution adopted by the present invention is:

A ceramic cartridge valve, having a leak-preventing structure, comprising the following parts: a valve body; an outlet pipe is connected to one end of the valve body; a groove surrounding the pipe is formed in the outer wall of the free end of the outlet pipe; a band-shaped sealing ring surrounds the outlet pipe is disposed in the groove;

Several adjustment elements are arranged between the internal wall of the band-shaped sealing ring and the bottom of the groove; a rotating water outlet head covers and is connected with the end of the outlet pipe on which the sealing ring is located;

Adjusting elements are fixed to the sealing ring in the circumferential direction; these elements include a connection part and an arcuate support part connected to the connection part; the connection part is connected to the band-shaped sealing ring; the arch-shaped support part extends from the

BE2019 / 5569 sealing ring.

Compared to existing techniques, the present invention has the following advantage: it effectively solves the problem of water seepage caused by the wear of the band-shaped sealing ring by having several adjustment elements, that is to say that is to say several arc-shaped connecting and support parts, between the internal wall of the strip-shaped sealing ring and the bottom of the groove.

Detailed description of the preferred embodiments:

A detailed description with reference to the accompanying figures relating to this valve is presented below, including a preferred embodiment of the present invention. This means that engineers can modify the invention described herein while continuing to achieve the beneficial effects of the present invention. Therefore, the following description should be understood as a broad understanding of this invention instead of a constraint.

As shown in Figures 1 to 4, a ceramic cartridge valve with a leak-preventing structure is made up of the following parts: a valve body; the valve body is provided with a ceramic cartridge; the transmission rod (7) of this cartridge is connected to an articulated handle, an inlet pipe (8) is connected to the water inlet end of the cartridge, and an outlet pipe (1) to the water outlet end of the cartridge; a groove (2) surrounding the water outlet pipe (1) is formed in the outer wall of the free end of the water outlet pipe (1); a band-shaped sealing ring (3) surrounds the outlet pipe (1) and is arranged in the groove (2); several adjustment elements are arranged between the wall

BE2019 / 5569 internal of the band-shaped sealing ring (3) and the bottom of the groove (2); a rotary head (6) for water outlet covers and is connected with the end of the water outlet pipe on which the sealing ring (3) is located. Adjusting elements are fixed to the sealing ring (3) in the circumferential direction; the adjusting elements include a connection part (4) and an arcuate support part (5) connected to the connection part (4); the connection part (4) is connected to the strip-shaped sealing ring (3); the arc-shaped support (5) extends from the sealing ring (3).

The outlet pipe head (6) is arranged so that the orientation of the water outlet of the outlet pipe head (6) can be adjusted as desired. After the outlet pipe (1) and the outlet pipe head (6) are connected, the sealing ring (3) is tightly fixed to the inner wall of the outlet pipe head (6) under the action of the arch-shaped support part (5). Even if the band-shaped sealing ring (3) is worn, it can still be tightly attached to the inner wall of the outlet pipe head (6) effectively preventing water leakage from the connection between the water outlet pipe (1) and the outlet pipe head (6).

In order to fix the sealing ring (3) in order to improve its sealing properties, the support part (5) is housed in the groove (2).

BE2019 / 5569

To standardize the support effect of the arc-shaped support part (5) on the band-shaped sealing ring (3) and so that its sealing property is good even in the case of wear, the connection part (4) is located in the middle of the arch-shaped support part (5) ·

In the present embodiment, the adjustment elements are distributed uniformly, so that their supporting effect d on the band-shaped sealing ring (3) is uniform in order to improve its sealing property.

In summary, this embodiment of the present invention effectively solves the problem of water seepage caused by the wear of the band-shaped sealing ring (3) by having several adjustment elements, that is to say -distribute several connection (4) and arc-shaped support parts (5), between the internal lateral wall of the strip-shaped sealing ring (3) and the bottom of the groove (2).

The above is only a preferred embodiment of the present invention and does not impose any limitation on the present invention. All changes concerning the technical solutions and the technical contents described in the present invention, made by engineers in the field without departing from the technical scope of the present invention, are always included within the scope of the protection of the present invention.
