Description

DESCRIPTION GAS INLET PIPE CONNECTOR 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 on the thermostatic faucet body. KNOWN STATE OF THE ART While connecting the gas inlet section to the gas inlet pipe in thermostat gas taps, in the state of the art, it is achieved by the tight fit method using brass standard bushings. In this method, in case of possible disassembly, the brass bushing cannot be removed from the valve body gas inlet section, causing the body to be completely scrapped. However, during mass production, the assembly time of the bushing is prolonged due to the tight fit to the faucet body. The patent application numbered EP3425252A1 is about a gas inlet connection piece developed to prevent leaks in the gas inlet section. In this invention, the said connection piece is a connection formed between the gas inlet pipe and the rubber gas hose, and these connection elements are related. The said connection part consists of two parts: the tail part and the connection part. It has a gap inside the connecting section, and the tail section is connected 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 a connection piece mounted on the gas inlet pipe using the tight fit method. DESCRIPTION OF THE INVENTION: The purpose of this invention, which is a connection piece that provides the pipe connection between the faucet body and gas inlet in thermostat gas taps, is to eliminate the currently used tight fitting connection and to create a connection piece that allows easy manual assembly with pliers. Another purpose of the invention is; Thanks to the notch forms at the end of the connection part, it is ensured easy one-way mounting to the product, preventing it from coming out backwards and also ensuring positioning. Another purpose of the invention is to allow maximum flow rate thanks to the oval form at the end.

In Figure 2, the connection part (3) and the gasket (2), which are the subject of the invention, are seen in exploded form. Figure 3 shows the connection of the connection piece (3) with the gas inlet section on the faucet body. Figure 4 shows the compressed and free perspective views of the connection piece (3). In Figure 5, the connection part (3) which is the subject of the invention and the notch (3.1) that allows it to be connected to the gas inlet section without tight fit, the sharp edge (3a) and oval edge (3b) of the notch (3.1) and the oval form (3.2) that provides maximum flow rate passage. ), the channel (3.3) opened along the connection piece (3) can be seen. DETAILED DESCRIPTION OF THE INVENTION The gas inlet opening section (5) in the thermostat gas tap (1); It is the section where the gas pipe providing gas supply is mounted. Gas enters the tap from this section and flows into the safety valve pool. In the current situation seen in Figure 1; In the assembly of the gas pipe and the gas inlet opening (5), a brass bushing (4) was used, which was mounted on the gas inlet by hammering and tight fitting method. When the brass bushing (4), which is in cylindrical form, is completely mounted to the gas inlet section with a tight fit, it partially closes the next opening (6) through which the gas passes to the safety valve. This situation causes the gas flow rate to decrease during gas flow. Additionally, the brass bushing (4) does not have the possibility of being disassembled since it is mounted with a tight fit. In case of any problem that occurs during installation or the brass bushing (4) needs to be replaced, the faucet body becomes completely scrap. In Figure 2, the connection part (2), which is the subject of our application, is seen together with the gasket (2), which is the sealing element, at the gas inlet opening (5). There are two notches (3.1) on the connection piece (3). The connection piece (2) can be easily mounted from the gas inlet opening (5) thanks to these notches (3.1) and the channel (3.3) opened along the middle of the notches (3.1). The said channel (3.3) allows the connection piece (3) to be clamped with pliers. When the connection piece (3) is compressed with pliers, the channel (3.3) closes to the limit allowed by the channel (3.3) opening and becomes the compressed channel (3.3.1). Thus, since its diameter is reduced, the connection piece (1) can easily pass through the gas inlet opening (5). The connection piece (3) can pass through the gas inlet opening (5) and move forward by turning. At this stage, thanks to the oval edges (3b) of the notches (3.1) on it, it provides a comfortable rotation movement by preventing any wear between it and the body due to the rotation movement as it rotates. The connection piece (3) rotates and moves forward until the sharp edges (3a) of the notches (3.1) rest on the diameter of the next opening (6) through which the gas will proceed and are fixed. It ensures fixation when it stops being compressed and returns to its previous diameter. The assembly is completed after the connection piece (3) is fixed to the next opening (5) through which the gas will travel. At this point, thanks to the oval form (3.2) on it, it does not block the entrance of the opening (5) and allows maximum flow rate. In case of any problem in this area, the connection part (3) can be disassembled by tightening it in the same way and turning it in the opposite direction, allowing re-assembly without the body being scrapped.
