TR DESCRIPTION Disconnector This invention is a valve that keeps the flow and pressure-related aspects of fluids under control in combi boilers and similar devices. It is defined as a separator product with a double check valve and a discharge system that prevents the installation water from mixing with the mains water. This valve has a weldless body structure made of thermoplastic material, compact in size, resistant to high temperatures and pressure. It has an aesthetic appearance with its aggressive external ribbed structure. It is a backflow preventer for the protection of users and the system in combi boilers and similar devices. The backflow preventer is a double check valve component that can stop dirty water from flowing back into the water system. Its working logic is that, in cases where the outlet pressure is greater than the supply pressure, if the outlet check valve fails for some reason, the outlet water is discharged without mixing with the feed water. Its purpose is to prevent contamination of drinking water by preventing installation water from mixing with mains water in combi boilers and similar devices. Technical Field to which the Invention Concerns: This invention is a component that controls the passage of water and similar fluids in combi boilers and similar devices and works to provide flow control. This transition control and discharge valve is an inlet and outlet element that opens and closes depending on certain conditions in installations containing fluid. It is used to isolate the pressure difference created by the fluid in a pipe from the pressure created by the fluid in the other pipe in the same system. It is a backflow preventer used in combi boilers and similar devices to protect users and the system from contamination. Thanks to the German KTW and the British WRAS Hot Drinking Water Approval, it is aimed to feed the closed circuit cysteines in such water systems and at the same time to prevent the mixing of drinking water and contaminated water. State of the Art This invention relates to a valve with a weldless body, designed to control and ensure flow of water and similar fluids in combi boilers and similar devices, produced from thermoplastic material in light and compact size, resistant to high temperatures, corrosion, chemicals and pressure. Metal valves and radiator heating systems, which are generally used in combi boilers and similar devices, cause rust and become difficult to control over time. At the same time, it has a heavier body than therinoplastic valves. Thermoplastic separator groups prevent reverse flow, are lighter and do not carry the risk of corrosion. However, their tolerance sensitivity is lower than their metal counterparts and therefore their production and design are much more difficult. This invention, by design, has overcome the tolerance problems experienced in thermoplastic backflow preventers, static seals and friction problems in sealing elements with thick contact systems, and is a high-pressure resistant, highly engineering product mounted with a plug-in system. This invention regulates fluid transfer by controlling the flow in water, and prevents backflow in combi boilers and similar devices to protect the users and the system. It consists of a body that includes the fluid transition system, check valve systems and moving elements, where the system is opened, closed and discharged, and 2 interface parts that connect the fluid with the surrounding elements. It provides a unidirectional controlled flow as long as the supply pressure is greater than the outlet pressure. If the output pressure is higher than the supply pressure, it blocks the reverse flow. Even if the outlet check valve, which prevents backflow, fails, it prevents contamination of the feed water by relieving the outlet pressure to the atmosphere. Brief Description of the Invention The invention can be described as a separator product with a double check valve and a discharge system that prevents the installation water from mixing with the mains water. In summary, its operation is based on the use of check valves in combi boilers and similar devices by controlling the flow of the fluid coming with a certain pressure in the feed side pipe. and static sealing elements close the drain and allow the water moving towards the device to pass to the outlet side. If the outlet check valve remains dysfunctional after loss of feed pressure, the backflow valve prevents backflow and discharges the fluid safely. This invention thus protects users, the system and the environment from contaminated fluids. Detailed Description of the Invention This invention is a valve with a weldless body that controls the passage of water and similar fluids in combi boilers and similar devices, is produced from therinoplastic material in light and compact size, is resistant to high temperatures, corrosion, chemicals and high pressure. The valve unit consists of 4 parts: an inlet, an outlet, a separator and a discharge group. The structure is formed by mounting different types of input and output connection parts on the body that houses the discharge and separation section. The separator section consists of check valve groups with static seals built on a flexible membrane and dynamic seals built into it.

Figure 3 (Backflow preventer) is the Disconnector Side View. Figure 4 (Backflow preventer) is the Disconnector Top View. Figure 5 (Backflow preventer) is the Disconnector Top View.

It is formed by squeezing it between the body part and the body part1(3). The second part is created by placing the inlet check valve group into the membrane (2) in this group. Additionally, there is an o-ring pressing on a conical surface inside the body, which provides dynamic sealing on the isolation valve group that separates the discharge section and this group. This group both allows one-way movement of the fluid from the inlet to the outlet and prevents the fluid from flowing back by preventing the flow in the opposite direction, and also ensures the discharge of the contaminated fluid in case the supply pressure drops and the outlet check valve malfunctions. Thanks to its special membrane (2) design and bellows structure, it can operate even at lower pressure differences than known techniques. Thanks to the design with a special membrane (2) with a self-contained O-ring, there is no need for an additional sealing element on the inlet interface part (1). In order for the dynamic o-rings to contact all surfaces perfectly and provide sealing, the corresponding contact surfaces are completely shaped with a conical structure to prevent friction. Since it operates without friction, it provides a longer-lasting and reliable seal. Thanks to the low friction of the sealing elements, a much more sensitive separator that can react to lower pressure differences is obtained. The entrance interface part (l) is attached to the front of the body section. In this way, it can easily adapt to different systems. The outlet section is formed by placing a check valve inside, which ensures one-way water flow, and attaching an interface piece to the outlet. If there are figures on the molds of plastic parts on an axis perpendicular to the mold parting line, these are called undercuts. The mold elements that are operated with different types of movements in order to mold the opposite angles in the mold are called cores. The interface (l) parts installed at the entrance and the interface (l4) parts installed at the exit are parts with a flexible nail locking system that are produced without the need for an additional core in the production mold. In this way, they can be grouped without requiring any additional parts (such as washers, washers, etc.), without torsion in the sealing elements, and without any screwing. By changing the front (1) and rear (14) interface parts, new, low-cost valve groups can be created that provide fast and economical solutions to different devices and different applications without affecting the main system. The purpose of this product is to prevent the water at the outlet from mixing with the inlet water and contamination by discharging the outlet water in case of a malfunction in the outlet check valve (in cases where the outlet pressure is higher than the inlet pressure). Since the check valves in the product use body parts as inlet-outlet bearing and sealing elements. It has a one-piece structure. Thanks to the functional parts within the body, the disconnector (backflow prevention) can be grouped with fewer parts. The sealing surfaces of the inlet (1) and outlet (14) interface parts are shaped without a molded connection surface. In this way, there is no sealing problem in these areas. The operation of the application subject (backflow prevention) disconnector system can be defined under two main headings: filling and discharge stages; (2) the membrane (2) stretches as the pressure increases, (3) It presses the inner part of the disconnector body to close the discharge port (15) with the O-ring (7) located on the outside. In this way, the discharge channel (15) is isolated. In the second stage, the mains pressure inlet check valve spring (6). ) force, it pushes the inlet check valve torpedo (5) back and water fills the middle section. During this period, the o-ring (7) outside the inlet check valve body (3) continues to block the discharge outlet (15). For this reason, since this section is isolated, water is not drained out. When the water pressure in the middle section increases enough to overcome the force of the outlet check valve (1 l), it pushes the outlet check valve (1 l) back and the mains water flows into the installation. Evacuation process; If the outlet check valve (II) cannot close the passage channel (defects) for any reason while the installation pressure is greater than "0" bar, or if the mains pressure is lower than the installation pressure for any reason, the inlet check valve body (3) and membrane (2) Due to the reverse pressure difference, it stretches back and moves towards the network side. In this way, the inlet check valve (3) and the o-ring (7) on it separate from the inner surface of the body and open the discharge channel. Since there is no obstruction line in front of the water on the network side, the water flows through the discharge section (15) on the network side until the installation pressure equals the atmospheric pressure. Exceptionally, if the downstream outlet check valve ( 11) fails, the drain valve opens to discharge the dirty liquid. This device is built as a positive-action device and the disconnector ensures a high level of safety in all situations. TR
