PLASTIC-BASED ANGLE BALL VALVE FOR RADIATORS AND PRODUCTION
METHOD THEREOF
Technical Field
The invention relates to plastic-based angle ball valves which allow direct connection of radiators with plastic-based pipes without requiring the use of adapters that otherwise permit the connection thereof with plastic-based pipes in heating industry.
The invention more particularly relates to the production method of plastic-based angle ball valves that allow direct connection of radiators with plastic pipes without requiring the use of plastic-based adapters.
Background of the Invention
Today, radiators are widely used in indoor areas, e.g. houses, work places, in heating industry. The connection between the radiators and pipes is achieved by radiator valves. Radiator valves can stop fluid flow when desired.
Said ball radiator valves are produced of metal-based material today. In order for the radiator valves to be connected to the plastic pipe system after mounting thereof in the radiator, it is required that they are mounted with plastic-based adapter having metal insert.
There is no other way of connection to the plastic-based pipe. Metal-based radiator valve can be produced by metal processing methods and it can only be connected by means of a screw thread system. Therefore, the plastic-based adapter comprising metal insert is mounted in the valve through the insert side thereof by means of screw connection while the plastic side of the adapter is mounted in the plastic-based pipe by socket welding.
In said system, plastic-based adapter is an extra part that is needed to be used. Said adapter causes some financial and technical losses in the heating system as follows:
Since screw threaded connection is performed and the use of an extra adapter is a must, each joint increases the possibility of leakage. Additional time and labor costs are incurred for connecting the plastic-based adapter, which creates a disadvantage for the system together with the cost of plastic-based adapter itself.
Another application in this field is the plastic-based ball radiator valves which are directly connected to metal radiators without requiring the use of an additional adapter. The disadvantage of these valves is that their body structures must be produced in a way to be big in size, which results in the necessity of consumption of more raw material and of using molds bigger in size, and thus requiring that bigger injection machines are preferred.
The patent search on the state of the art revealed the Patent Application No. TR2007/02519. The abstract of this application is as follows: the invention relates to a radiator valve which comprises at least one bottom entry ball/globe valve, at least one valve tail allowing connection with the radiator, and at least one insert connected to said valve tail; wherein it further comprises a plastic adapter configured on the plastic valve body in an integrated manner.

Detailed Description of the Invention
The invention is a radiator valve (1) which has a welding socket (8) which is produced in a way to be integrated with the valve body (6), i.e. as a single piece. It comprises a welding socket (8) which is integrated with the valve body (6) and formed in the same y-axis as that of said valve body and a moving group (7) operating in the same y-axis as that of said valve body (6) and of said welding socket (8).
It also has a metal insert (2) fixed in the connection, inlet (6.1 ) of said valve body (6) and a valve tail nut (4) allowing connection between said metal insert (2) and valve tail (3). Also comprised is an inner body (7.5) which integrally holds said flywheel shaft (7.1), shaft shell (7.2), and the ball (7.4); has a two-piece structure; and is provided thereon with a contact point (14). In Fig. 1 , the perspective view of the plastic-based angle ball valve (1 ) for radiators is illustrated.
Said angle ball valve (1 ) for radiators is made of the following main components; valve tail- (3), metal insert (2), valve tail nut (4), flywheel (5), moving group (7), and welding socket (8) integrated with the valve body (6).
The angle ball valve (1) for radiators is connected to the radiator by being screwed by means of the valve tail (3). The welding socket (8) is formed integrally with the valve body (6) as an extension thereof and enables the angle ball valve (1) for radiators to be directly connected with plastic tubes by means of socket welding.
Said valve body (6) encloses the moving group (7), at the same time embedding the. flywheel (5), as well.
In the preferred embodiment of the invention, said valve body (6) is made of plastic material or plastic derivatives. In Fig. 2, the side cross-sectional view of said plastic-based angle ball valve (1 ) for · radiators is illustrated.
Said valve tail (3), metal insert (2) and valve tail nut (4) are made of metal material; wherein the metal insert (2) is fixed in the valve body during injection stage, and wherein the valve tail (3) and the valve tail nut (4) are connected with the valve body (6) by being screwed on the metal insert (2). The valve tail (3) is located in the radiator by also being screwed and the valve tail nut (4) positioned on the valve tail (3) fixes the plastic-based angle ball valve (1) for radiators onto the radiator thanks to the movable connection property thereof. The production of the plastic-based angle ball valve (1) for radiators is achieved by the pin system disposed in the plastic injection mold (9), as well as by the movable mold body (13) and the stable mold body (12).
In Fig. 3, the cross-sectional mounted view of the mold (9) for the plastic-based angle ball valve for radiators is given.
First, a metal insert (2) is located on the stable mold pin(11) which is disposed in said mold (9).
Afterwards, the moving group (7) is positioned on said stable mold pin (1 ).
During closure of the movable mold plate (13) in direction b, movable mold pin (10) moves in direction d, either simultaneously or independently. Said movable mold pin(10) centralizes the moving group (7) through the ball (7.4) hole. When the mold is fully closed, the movable mold plate (13) contacts with the moving group (7) through the contact point thereof, thereby performing fixation by compressing said moving group (7) between the stage (15) on the stable mold pin (1 1) and the movable mold plate (13), and thus making the moving group (7) to act as a non-movable single piece. Hence, the pressurized fluid is prevented from leaking through the joint of the moving group (7) or from displacing it during injection process. The ball valve body (6) is formed by the injection of the plastic material into the mold (9) by means of the injection machine.
While the movable mold plate (13) opens in direction a, the movable mold pin (10) moves in direction c and gets away from the stable mold plate (12). Thus, the angle ball valve for radiators which is formed integrally with the welding socket (8) and the valve body (6) is allowed to be removed from the stable mold plate (12).
As a result, the valve body (6) is produced as a single piece in a way to include welding socket (8), metal insert (2), and moving group (7) which together form the plastic-based angle ball valve (1 ) for radiators. The production of the plastic-based angle ball valve (1) for radiators is completed by mounting the flywheel (5) into the moving group (7) located inside the valve body (6), and mounting the valve tail (3) and the valve tail nut (4) into the metal insert (2).
The valve tail (3) located on the plastic-based angle ball valve (1 ) for radiators, the production of which has thus been completed, is connected to the radiator by preferably winding thereon linen or teflon.
The body (6) of the plastic-based ball radiator valve (1) and the welding socket (8) formed as an extension thereof as a single piece are welded in the plastic pipe by socket welding.
The valve tail nut (4) disposed on the valve tail (3) connected to the radiator and the metal insert (2) are screwed to one another and the plastic-based angle ball valve (1 ) for ' radiators is connected with the radiator. The plastic-based angle ball valve (1 ) for radiators is turned on and off by being controlled by the flywheel (5).
The hot water inside the plastic tube gets to the radiator thanks to the plastic-based angle ball valve (1) for radiators and said hot water heats the radiator, which, in turn, heats the environment.
