Description

DESCRIPTION GAS INLET PIPE CONNECTION TECHNICAL FIELD This invention relates to a gas inlet pipe connection piece that provides ease of installation and maximum gas passage used in the gas inlet pipe connection of thermostatic faucet body. KNOWN STATE OF THE TECHNOLOGY In thermostatic gas faucets, when the gas inlet section and the gas inlet pipe connection is made, a standard brass bushing is used and a tight fit method is used. In this method, in the event of disassembly, the brass bushing cannot be removed from the gas inlet section of the valve body, causing the entire body to be scrapped. However, in the mass production phase, the tight fit of the bushing to the faucet body prolongs the installation time. The patent application numbered EP3425252A1 relates to a gas inlet connection piece developed to prevent leaks in the gas inlet section. The connection piece referred to in this invention relates to a connection formed between the gas inlet pipe and the rubber gas hose, and these connection elements are related. The connection piece consists of two sections: a tail section and a connecting section. The connecting section has a cavity within it, and the tail section connects to the rubber gas hose. When the spacers used in the connection mentioned here are examined, it is seen that the gas inlet pipe connection piece here is also a connection piece mounted to the gas inlet pipe using a tight fit method. DESCRIPTION OF THE INVENTION The purpose of this invention, which is a fitting that connects the faucet body to the gas inlet and the pipe in thermostatic gas faucets, is to eliminate the currently used tight fit and provide a fitting that allows for easy installation by hand with pliers. Another purpose of the invention is to prevent backflow while also ensuring positioning by providing easy one-way installation thanks to the notched forms at the end of the fitting. Another purpose of the invention is to allow maximum flow rate through the oval shape at the end. DRAWINGS The applications of the present invention, briefly summarized above and discussed in more detail below, can be understood by referring to the example applications of the invention depicted in the appended drawings. However, it should be noted that the accompanying drawings depict only typical applications of the invention and are not intended to limit its scope, as the invention could therefore allow for other equally effective applications.

Figure 2 shows the connection piece (3) and the gasket (2), which are the subject of the invention, in an exploded form. Figure 3 shows the connection of the connection piece (3) with the gas inlet section on the faucet body. In Figure 4, perspective views of the connection piece (3) in compressed and free states are seen. In Figure 5, the connection piece (3), which is the subject of the invention, and the notch (3.1) that ensures connection to the gas inlet section without a tight fit, the sharp edge (3a) and the oval edge (3b) of the notch (3.1) and the oval form (3.2) that ensures maximum flow rate passage, and the channel (3.3) opened along the connection piece (3) are seen. DETAILED DESCRIPTION OF THE INVENTION In the thermostatic gas tap (1), the gas inlet opening section (5) is the section where the gas pipe providing gas supply is mounted. The gas enters the tap from this section and progresses and fills the safety valve pool. In the current situation seen in Figure 1; A brass bush (4), mounted to the gas inlet using a tight fit method, was used during the installation of the gas pipe and the gas inlet opening (5). When the cylindrical brass bush (4) is completely installed in the gas inlet section with a tight fit, it partially closes the next opening (6) through which the gas flows and passes to the safety valve. This causes a decrease in gas flow during gas flow. Furthermore, because the brass bush (4) is installed with a tight fit, it cannot be disassembled. If a problem occurs during installation or if the brass bush (4) needs to be replaced, the faucet body is completely scrapped. Figure 2 shows the connection piece (2), which is the subject of our application, in the gas inlet opening (5) together with the sealing element, the gasket (2). The connection piece (3) has two notches (3.1). The connection piece (2) can be easily installed through the gas inlet opening (5) thanks to these notches (3.1) and the channel (3.3) opened along the length of the notches (3.1). This channel (3.3) allows the connection piece (3) to be tightened with pliers. When the connection piece (3) is tightened with the pliers, the channel (3.3) closes to the limit allowed by the channel (3.3) opening, becoming the compressed channel (3.3.1). Thus, due to the reduced diameter, the connection piece (1) can easily pass through the gas inlet opening (5). The connection piece (3) can be advanced by rotating through the gas inlet opening (5). At this stage, the oval edges (3b) of the notches (3.1) prevent wear caused by the rotational movement between the body and the connecting piece (3) while rotating, ensuring a smooth rotational movement. The sharp edges (3a) of the notches (3.1) rotate until the connecting piece (3) is secured against the diameter of the next opening (6) through which the gas will flow. In this way, the notches (3.1) ensure both positioning and, once positioning is complete, fixing when the connecting piece (3) is released from the pliers and returns to its original diameter. Installation is completed after the connecting piece (3) is secured to the next opening (5) through which the gas will flow. At this point, the oval shape (3.2) on the connecting piece does not block the inlet of the opening (5), allowing for maximum flow rate. In case of any problem that may occur in this area, the connection piece (3) can be disassembled by tightening it in the same way and rotating it in the opposite direction, allowing reassembly without scrapping the body.
