[0017] Detail Description

[0018] In order to understand more fully, this invention will be described in more detail by referring to the accompanying drawings and by following the reference numbers which will be explained further. Referring to Figure 1, which is a perspective view of the embodiment of the cylinder valve in this invention, it can be seen that the top part can be connected to a gas stove or gas burner in general. Meanwhile, the bottom part which is equipped with threads (black) is the part that can be connected to a gas cylinder which can contain compressed natural gas. On the right and left sides are equipped with cooling plates with a shape adapted to the cylinder valve of this invention.

[0019] Referring to Figures 2 A and 2B, which are perspective views of the embodiment of the present invention, you can see each component that makes up the first part of the cylinder valve in question. This first part includes 32 (thirty-two) components which will be explained further. This first part is part of a modification of the previous invention so that the ability and capacity of gas flow is increased. This first part includes a number of lock bolts which have the function of combining the spring housing and first level pressure regulating membrane with the main membrane housing and the second part. The lock consists of four first level lock bolts (lock bolt stage 1) (1A), four second level lock bolts (lock bolt stage 2) (IB), and two third level lock bolts (lock bolt stage 3) (1C). The four first level locking bolts (1A) have the function of combining the spring housing with the first level pressure regulating membrane on the main membrane housing. Four second level locking bolts (IB) function to combine the spring housing and the second level pressure regulating membrane in the main membrane housing. Meanwhile, the two bolts that lock the cylinder valve and the membrane housing have the function of firmly uniting the first and second parts of the cylinder valve in this invention.

[0020] The first part is also equipped with a second stage membrane housing (2). This housing can be occupied by a second stage spring (3), locking nut (4), membrane retaining plate ring (5) and round O-ring (6). The second stage spring (3) has the function of regulating the gas outlet pressure at the second stage. In an effort to ensure that the position of the second level valve is in a fixed position, a locking nut (4) is needed. To ensure the strength of the membrane in this invention, it is installed with a membrane retaining plate ring (5). Round O-ring (6) is still needed to ensure that gas does not escape.

[0021] The first part of this invention is also equipped with a second stage membrane (7) which functions to regulate the exit gas pressure at the second stage. To ensure that gas does not escape or leak, the cylinder valve in this invention is equipped with a round O-ring (8). This second level membrane is strengthened by a membrane retaining plate ring (9).

[0022] The membrane in this invention requires a separate housing which is called the membrane main house

[0023] (10). In this housing there is a place for reducing pressure on the first and second levels. When used, the valve in this invention is also equipped with a 50 kg LPG gas outlet connector (outlet connector)

[0024] (11) which has the function of connecting to a liquid petroleum gas (LPG) valve. In this adapter connector, C clips (12), adapter spring retaining (13), adapter spring valve (14), and valve adapter (15) are placed. This outlet is needed for users of the 3 kg and 12 kg versions of LPG. Apart from that, this connector can also be paired with a G52 adapter (16) which is widely sold on the market for gas cylinders with LPG fuel. C clamps (12) are used to hold adapter valves for LPG gas with a capacity of 50 kg, and / or 12 kg.

[0025] The first part also includes a burst disk housing coupled to the membrane main housing (10), as well as for the placement of the burst disk spring (18), and the burst disk (19). In this rupture disc housing, a membrane housing safety device is placed (not visible). This disc is used to ensure safety in the event of a leak or excess pressure or other things related to gas use. Meanwhile, the rupture disc spring (18) is a means of protecting the membrane housing which can function by releasing gas if the pressure inside the membrane housing exceeds a specified limit (for example 15 bar). On the other hand, the burst disk (19) is also a means of holding the valve and will release gas if the pressure in the membrane housing exceeds a predetermined pressure (for example 15 bar).

[0026] Another component of the first part is the second stage valve seat (20) which functions to regulate the exit pressure of the gas at the second stage. This valve is held by a valve seat stopper (21) which functions to restrain the movement or shift of the second stage valve seat (20) at a certain distance. Movement or shifting of the second stage valve seat (20) can be carried out by the first stage push link (22) with horizontal to vertical movement or vice versa. The regulation of the gas pressure leaving the first stage is carried out by the first stage valve rod (23). The first stage push link hinge (22) and the first stage valve rod (23) are connected to the push link axle rod (24) so that they can lock the position of the valve hinge in question. To direct the movement of the valve, a push link guide rod component (25) is needed as a rod that guides the movement of the valve which is attached to the first stage push link hinge (22). In strengthening the first part it is also equipped with a membrane retaining plate ring (26). The membrane retaining plate ring (26) will function to strengthen the inner membrane. Meanwhile, regulating the pressure of the first stage exit gas is carried out using a first stage membrane (27). Meanwhile, to strengthen the membrane, a membrane retaining plate ring (28) is provided. The membrane retaining plate ring (28) has the function of reinforcing the outer membrane. The membrane configuration in this invention can be strengthened with better locking via a small plate ring (29) as a membrane holder and functions to lock the nut better. In the locking, a locking bolt (30) is provided so that the bolt can lock the valve stem with the membrane. The outer end of the first part of the invention is equipped with a first stage spring (31) which regulates the gas outlet pressure in the first stage. The first stage spring (31) is paired with the first stage membrane housing (32) as a seat for the spring in question. Then this housing can be fixed / locked with four first level locking nuts (1A).

[0027] The cylinder valve of the present invention also includes a second part as a main part which is connected to the first part above. This second part consists of components with reference numbers from 33 to 51 as follows. The second part has a plug bolt component (33) which functions to close the tube valve. For safety when gas is filled or used, the valve in this invention is equipped with a temperature safety valve (34). This valve functions as a safety device installed on the valve and will work by releasing gas if the pressure inside the membrane housing (10) exceeds 300 bar or the temperature exceeds °C. Another component as the main support for the second part of this invention is the ball valve housing (35). This housing has the function of housing the ball valve (37). This valve will function to open and close the gas that comes out of the gas cylinder. The high pressure of the gas coming out of the gas cylinder can be reduced through a first stage reducing power valve (36).

[0028] In an effort to ensure that the ball valve (37) remains in position, the second part of the invention is equipped with a ball valve retainer (38). This valve holder functions to keep the ball valve (37) in its original position and does not move out of position. Meanwhile, to ensure that gas does not leak, the cylinder valve of this invention is equipped with a ball valve seal (39). In this way, the contents of the gas cylinder to which the valve of this invention has been installed can be guaranteed to be safe from leaks.

[0029] The entry and exit of gas from the cylinder can be controlled by a ball valve which is equipped with means to open or close it. This means is in the form of a valve stem (40). The valve stem (40) is also equipped with a round O-ring (41) which has the function of preventing leaks through gas seepage into the valve stem. On the other hand, to ensure that the valve stem and O-ring of the valve in this invention remain in position, a valve lock (grand nut) (42) is provided. To open and close the valve, this invention provides a means of rotating the valve (valve handle) (43). By means of rotating this valve, when using / using the valve of this invention it can be opened and when not in use it can be closed. This open valve can flow gas, whereas when it was close the gas will stop flowing. The valve rotation facility is also equipped with a lock nut (44) which functions to lock the valve rotation.

[0030] When the valve of this invention has been attached to a gas cylinder, to facilitate filling the cylinder, the valve of this invention is equipped with a filling means that includes a first stage spring (45). The spring will push the one-way valve in an attempt to close the filling facility when there is no filling. Another component of the filling facility is a one-way valve (46). This valve will be closed by the push of the first stage spring (45) when there is no gas filling, while when filling this valve will be open. The next component that makes up the filling means is the quick coupler (47). This quick coupler will make it easier to fill gas cylinders that have been installed with the valve of this invention. The filling facility is also equipped with a second stage spring (49). Through this second stage spring filling can be carried out because the second stage valve (50) will be closed when it is not connected to the filling valve. All components of the filling facility are placed in the second stage valve housing (51) which is paired with the quick coupler (47).

[0031] The third part of the cylinder valve in this invention is the evaporator part. This part can also be used as a complement which has the function of evaporating steam or dew formed either due to use or other conditions so that the valve of this invention is protected from blockage due to dew or steam formed. This section consists of the first evaporator (evaporator A) (52) and the second evaporator (evaporator B) (53). The shape of the evaporator can vary and in general it can be made of aluminium with an arrangement of plates like evaporators in general.

[0032] The material used for the cylinder valve in this invention can be stainless steel. However, in the preferred embodiment of the present invention, the materials used are as follows. The first part as a modification material can be made from aluminium. The second part is the main part. Most of the material is made from brass steel, while the third part can be made from aluminium.

[0033] The entire disclosure and the images attached to this description are the preferred embodiment, other modifications may be possible. However, the main scope of this invention is as expressed in the claims of this invention.
