[0001] The present invention relates to a jointless and welding-free valve that controls the passages of fluids such as gas, air, water, steam and oil in combi boilers and the similar devices, that is designed to ensure the flow, that is manufactured from a plastic material and that is resistant to high temperatures, chemicals, and pressure.

[0002] Said valve is of a compact size that is positioned between pipes in combi boilers and similar devices and controls the flow of coming fluids through a certain pressure. It regulates the transfer speed by controlling turbulent flow conditions in the water. It relates to a device that is embodied in the pipe, that adjusts and stops the flow of a fluid being transferred through the pipe and initiates the stopping of flow or increases and decreases the flow rate of the fluid.

Technical Field of the Invention

[0003] The present invention is a component that controls the passage of fluids such as gas, air, water, steam, and oil and ensures to control the flow in combi boilers and similar devices. Said valve is an inlet and outlet member that opens and closes depending on the condition in the installations with fluids. They are safety apparatus that decreases the pressure by discharging the fluid out of the system in case of pressure increase in systems, in which the fluid pressure constitutes importance or that protects the device by controlling the coming high-pressure fluid in the device and that cuts off the fluid communication in case of emergency. It is also employed to isolate the pressure difference caused by the fluid in a pipe from the pressure caused by the fluid in another pipe in the same system.

State of the Art

[0004] Metal valve systems used in the combi boilers and similar devices cause corrosion over time, thereby leading to a hard-to-control. Furthermore, their main object is to control the turbulent flow conditions in the water and thus to regulate the fluid transfer. The body comprises the fluid passage system and moving elements, in which the opening and closing are performed, encompasses and guides the fluid, allows for joining with pipes, shows resistance to the pressure, and protects safely the device and medium from fluids by means of its tightness.

Brief Description of the Invention

[0005] The present invention relates to a welding-free valve that controls the passages of fluids such as gas, air, water, steam and oil in combi boilers and the similar devices, that is designed to ensure the flow rate, that is manufactured from a plastic material and that is resistant to high temperatures, chemicals, and pressure. The valve comprised of nail components is characterized by becoming a single piece, such that components constituting the device itself are fitted together and nails are placed, so that the assembly is completed.

[0022] The present invention is a flow-controlled filling valve comprised of two main

components, namely body (1) and plug (4), which is sealed by means of elements, known as two O-ring (3) sealing elements. The body (1) constitutes a cover function for the valve and a bearing for the opening-closing handle (6). Opening-closing handle (6) transfers the opening-closing force and movement applied externally on the valve to the plug (4) being the opening-closing member. O-rings provide tightness between moving and fixed components. Bolt (5) provides the connection between the handle (6) and the plug (4) and the handle (6) is demounted by disassembling the bolt (5) on demand. In case the valve can be controlled manually in the device, the valve may be opened and closed by means of the plug (4) with nails thereon without requiring the handle (6).

[0023] The valve comprised of nail components is characterized by becoming a single piece, such that components constituting the device itself are fitted together and nails are placed, so that the assembly is completed. [0024] In order to provide the necessary pressure to operate a system, the valve is activated by means of the handle (6) and the fluid passage is allowed and when the necessary pressure is provided, the valve is closed through the same handle (6), thereby keeping the pressure in the system. The handle (6) is characterized to allow for the external control of the device outside the device according to the position of the valve in the system. If the valve is in a position such that it cannot be reached or controlled manually, the valve may be controlled through the handle (6) mounted on its body (1) by means of the bolt (5). In case the valve is in a reachable position in devices, opening and closing functions thereof may be performed through the plug (4) without requiring the handle (6) and bolt (5).
