TH32403B - Pressure reducing valve - Google Patents

Abstract

The pressure reducing valve 2 incorporates a movable device in the form of a 12' piston which is actuated by the injection orifice in the filling to prevent fluid flow between The inlet device 8 and the sub chamber are adjusted to 50 and to allow fluid flow through the valve. Between inlet 10 and inlet 8, this valve allows the gas tank to be filled while There is still a pressure reducing valve 2 in its original position.

Claims (7)

1. A pressure reducing valve incorporating a body section (4) that defines the inner filling chamber (6) inlet path (8) for allowing fluid to enter the containment chamber (6) flow path. Filed from Way of entry (8) to the outlet path (10) to drain the fluid, the received valve path Movable reception in the containment chamber (6) for the flow control of the fluid along the flow path, the valve path including the piston (12) on the near face of the piston (12) that has been formed. Formed to have a valve seat (16) located in the first position of the piston (12) restricts the flow of fluid along the line. Flow path The front flow piston (12) in conjunction with the working surface (35) of the fuselage (4) in the sub-chamber boundary (50), the trajectory (27, 31) permits contact between Inlet path (8) and sub chamber (50), where the manipulation causes fluid to enter the inlet path (8), the piston (12) travels from the first position of the piston to the second position. To allow some of the fluid to flow Along the flow path to the outlet path (10) the remainder of the fluid flows from the inlet path (8) through the path (27, 31) to the sub chamber (50) where the fluid provides The force exerted on the far end of the piston (12) and the route optimized for the receiving of the stimulation by the filling mouth of the filling To prevent the flow of fluid along the aforementioned path (27,31) between the inlet (8) and the adjusting sub-chamber (50) to allow fluid flow through the valve between the outlet device ( 10) and the inlet path (8), which is characterized by that the near end of the piston (12) has a diameter In the middle of the far end And that the path (21) has been established for all When connecting the piston (12) to the first such position. To the second position where the flow path opens, where such force exerted by the fluid in the sub-chamber (50) on the far end of the piston (12) is always exerted against the piston (12) against its action throughout. The times of the path (21) and where the path Such that it has been optimized for the stimulation by the injectable pipe in the package is Movable path 2. The pressure reducing valve, as held in claim 1, where the path of motion is in the form of a piston (12 \ '), is accepted in a slip-on inside the piston ( 12) and get formed to have The sealed path (64) at the far end of the device is for shoulder support (37) in the surface (35) of the fuselage (4) for protection of fluid between the channel path. Inlet (8) and Adjustment Sub Room (50) 3. The pressure reducing valve, as held by claim in Article 1, where the path for action All the time towards the piston (12) is the compression spring (21). 4. Pressure reducing valve, as held by one of the right clause 1,2 or 3. Where the path For the constant action on the piston (12), it consists of a passage (22) in the body (2) that extends from the fluid source under pressure to the area in the containment chamber (6) between the shoulders (13) formed. Formed in packing chamber (6) and shoulder (19) formed on piston (12). 5.Pressure reducing valve, as held by one of the rights claims 1 to 4. Where valve seat 16 has an annular shape 6. The pressure reducing valve, as held by one of the rights clauses 1 to 5. Where the inlet path (8) is ring-shaped and the outlet path (10) is arranged in the middle of the Ring formed by inlet path (8) 7. The pressure reducing valve, as held in claim 1, where the movable path consists of a convex section (72) formed in front (20) of the far end of Pistons (12), which are welded in such a way as to prevent fluid leaks to the support (73) in the surface (35) of the body (4) to prevent the flow of Far between the inlet path (8) and the adjusting sub-chamber (50)
