Description

Technical Field

[0001] This invention pertains to the structure of rupture valves, specifically an angle rupture valve that can withstand pressure on both the inlet and outlet sides simultaneously. Background Technology

[0002] In nuclear power, aerospace, and other industrial sectors, a type of critical valve employs a burst valve structure. These valves are pyrotechnically actuated and are required to remain normally closed with zero leakage under normal operating conditions. In accident situations or when needed, the valve opens rapidly to achieve crucial safety functions such as fluid flow and pressure release. Burst valves offer high reliability and rapid opening capability, typically less than one second.

[0003] Common rupture valves are typically straight-through, single-sided pressure-bearing, with a relatively simple structure and limited application conditions. In the newly developing small modular reactors (SMRs) for nuclear power, a type of valve is needed that can quickly open as a rupture valve. Furthermore, due to compact layout requirements, its inlet and outlet sides are arranged at right angles. Crucially, both the inlet and outlet sides of the system containing the valve are pressure-bearing, allowing the valve to quickly open and facilitate media flow in the event of abnormal pressure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an angle-type burst valve that can withstand pressure on both the inlet and outlet sides simultaneously.

[0005] The present invention is implemented as follows: an angle-type burst valve with simultaneous pressure at both the inlet and outlet, comprising a valve body, a piston disposed within the valve body, an initiation device disposed at the end of the piston, and a connecting pipe cap disposed below the valve body.

[0006] As described above, an angle-type rupture valve with simultaneous pressure at both the inlet and outlet is provided with a pressure ring between the piston and the detonation device.

[0007] As described above, an angle-type rupture valve with simultaneous inlet and outlet pressure is provided, wherein the detonation device is connected to the valve body by bolts, and a sealing ring is provided on the contact surface.

[0008] As described above, an angle-type burst valve with simultaneous pressure at both the inlet and outlet has a three-way angle structure, meaning that the inlet and outlet sides of the valve body are at a 90° angle, and the piston chamber of the valve body forms a 90° angle with both the inlet and outlet sides of the valve.

[0009] As described above, an angle-type burst valve with simultaneous inlet and outlet pressure is provided, wherein the piston top is provided with a protruding annular thin edge, and the piston is supported on the step of the valve body by the thin edge during installation, and then fixed by a pressure ring.

[0010] As described above, an angle-type burst valve with simultaneous pressure at both the inlet and outlet has two connecting pipe caps, one on the inlet side and one on the outlet side of the valve.

[0011] As described above, an angle-type burst valve with simultaneous pressure at both inlet and outlet is provided, wherein the connecting pipe cap is an integral blind pipe.

[0012] The significant advantages of this invention are: First, it possesses the advantages of a burst valve: zero leakage and rapid and reliable opening function; it adopts an angle burst valve structure, which is designed for angle pipe arrangement, and the valve body structure is horizontally placed with low overall height, making it flexible, compact, and easy to install; the design of two pipe caps allows for applications such as simultaneous pressure on the inlet and outlet, pressure on only the inlet side, or pressure on only the outlet side, making it suitable for more complex working conditions. Attached Figure Description

[0013] Figure 1 A schematic diagram of an angle burst valve that bears pressure on both the inlet and outlet sides, provided by the present invention;

[0014] Figure 2 The AA section view clearly shows the inlet and outlet structure of the angle burst valve.

[0015] In the diagram, 1 is the valve body; 2 is the detonation device; 3 is the piston; 4 is the pipe cap; 5 is the pressure ring; 6 is the sealing ring; and 7 is the bolt. Detailed Implementation

[0016] like Figure 1 As shown, an angle-type rupture valve with simultaneous pressure on both the inlet and outlet sides includes: a valve body 1, an initiating device 2, a piston 3, a connecting pipe cap 4, a pressure ring 5, a sealing ring 6, and bolts 7. The valve body 1 features an innovative three-way angle structure, with the piston chamber forming a 90° angle with both the inlet and outlet sides. The horizontally positioned piston chamber is shown in the diagram. The initiating device 2 is mounted on the far left of the valve body 1 and connected to the valve body 1 via bolts 7. A sealing ring 6 is installed between the valve body 1 and the initiating device 2 to form a seal and prevent external leakage after the valve is opened. The piston 3 is installed in the piston chamber of the valve body 1, and its left side has a protruding annular thin edge, which is fixed to the valve body 1 by the pressure ring 5. The bottom of the piston 3 has two grooves corresponding to the heads of the two connecting pipe caps 4. An angle-type through hole is designed in the middle of the piston 3. A connector cap 4 is installed on each of the inlet and outlet sides of the valve body 1. The connector cap 4 is installed into the valve body 1 through the positioning hole. The connector cap 4 is an integrated blind pipe design with a small diameter and thin wall at the head, which extends into the groove below the piston 3. The thin wall at the head can be designed according to the different pressures on the inlet and outlet sides.

[0017] like Figure 1The diagram shows the closed state of an angle-type burst valve structure with simultaneous pressure on both the inlet and outlet sides. When the valve needs to be opened, the detonating device 2 receives a signal and detonates, rapidly generating high pressure in the piston chamber of the valve body 1. The generated pressure pushes the piston 3, causing the protruding annular thin edge on the left side of the piston 3 to break off. The piston 3 then moves rapidly away from its fixed position, and the slot at the bottom impacts the heads of the two connecting pipe caps 4, causing the heads of the connecting pipe caps 4 to be knocked off and confined in the slot of the piston 3. The piston 3 continues to move until it reaches the bottom of the valve body 1, and the angle-type opening in the middle of the piston 3 aligns with the inlet and outlet sides of the valve, thus fully opening and activating the valve.

[0018] Figure 2 This is a cross-sectional view (AA section) of an angle rupture valve structure that is simultaneously pressurized on both the inlet and outlet sides. The inlet and outlet structures of the angle rupture valve, as well as the structure where the head of the connector cap 4 is installed into the slot of the piston 3, can be clearly seen from another direction.

[0019] The technical features of this invention are as follows:

[0020] 1. Three-way angle structure

[0021] This structure innovatively adopts a three-way angle design to meet the layout requirements of angle-type pipe connections. Specifically, the inlet and outlet sides of the valve body are designed at a 90° angle, and the piston chamber of the valve body also forms a 90° angle with both the inlet and outlet sides of the valve. This design allows the main body of the valve to be horizontally positioned, effectively reducing the overall height of the valve, making it flexible, compact, and easy to install.

[0022] 2. Piston Structure

[0023] Conventional rupture valves use a bolt to suspend the piston, with a weakening groove in the middle of the bolt. When the detonating device is activated, the bolt breaks, causing the piston to disengage. This valve employs a unique piston structure with a protruding annular thin edge at the top. During installation, the piston rests on the step of the valve body via this thin edge and is then secured by a pressure ring. When the detonating device detonates, the resulting pressure breaks the annular thin edge, causing the piston to disengage. This design is compact, easy to install, and reliable.

[0024] 3. Double-ended cap design

[0025] This valve adopts an angle-type structure and a double-cap design, meaning that a cap is installed on both the inlet and outlet sides of the valve. The caps are integrated blind pipes, which effectively ensures zero leakage when the valve is closed. Simultaneously, the dual-cap design allows the inlet and outlet sides to bear pressure simultaneously, enabling this valve to be used in multiple applications, such as simultaneous pressure at both inlet and outlet, pressure only at the inlet side, or pressure only at the outlet side, making it suitable for more complex operating conditions.
