Description

Technical Field

[0001] This utility model relates to the technical field of split-type quick-closing valve systems, and in particular to a split-type quick-closing valve system. Background Technology

[0002] The ship's quick-closing valve control system is a core device for ensuring the safety of ship pipelines. Traditional systems often adopt an integrated valve box structure, which integrates components such as air source, control, and detection into a sealed box.

[0003] The existing shipboard quick-closing valve control system has the following problems in use: With its large overall size and fixed layout, the integrated quick-closing valve box has strict requirements on the size and shape of the installation space, making it unsuitable for core functional areas such as the SOS room and engine room auxiliary machinery area on ships. These spaces are extremely small and have various equipment densely packed, so the integrated quick-closing valve box cannot be directly installed due to its size. If the integrated valve box is forcibly reduced in size to fit the small space, it will lead to crowded internal piping and insufficient maintenance space. At the same time, it will affect the accuracy and convenience of pressure detection and valve operation, reduce the stability of system operation. In addition, the traditional integrated system has an integrated design of air supply and control unit. When a single component fails, the whole system must be disassembled for maintenance, resulting in low maintenance efficiency. Furthermore, the layout of the emergency manual air supply interface is unreasonable, making it impossible to quickly connect to the emergency air source. Utility Model Content

[0004] This invention addresses the challenges of large overall size, fixed layout, and stringent requirements for installation space dimensions and shape, making it unsuitable for core functional areas such as shipboard SOS rooms and engine room auxiliary machinery areas where space is extremely limited and various equipment is densely packed. Integrated quick-closing valve boxes cannot be directly installed due to their size limitations. Forcing a reduction in the size of the integrated valve box to fit the confined space would lead to crowded internal piping, insufficient maintenance space, and would affect the accuracy and convenience of pressure detection and valve operation, reducing system stability. Furthermore, the traditional integrated system's air supply and control unit are designed as a single unit, requiring complete disassembly and repair in case of a single component failure, resulting in low maintenance efficiency. Additionally, the unreasonable layout of the emergency manual air supply interface makes it difficult to quickly connect to an emergency air source. Therefore, this invention provides a split-type quick-closing valve system.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides a split-type quick-closing valve system, which includes: An air cylinder unit and a wall-mounted control box unit are connected by a quick-connect air pipeline.

[0006] The air cylinder unit includes an air cylinder body, the bottom of which is provided with a foot support, the air inlet end of which is provided with a shut-off check valve and connected to the air outlet of the ship's main air cylinder dryer, and the air outlet end of which is provided with a shut-off valve. The wall-mounted control box unit includes a control box body, a door, an air inlet pipe, and a main air outlet pipe. The door is hinged to the front of the control box body, and an observation window is fitted onto the surface of the door. The main air outlet pipe is installed inside the control box body by a fixing clamp. An air outlet pipe is fixedly connected to the side surface of the main air outlet pipe. The end of the air outlet pipe passes through the control box body and is fitted with an air outlet clamp connector. The air inlet pipe is connected to the air outlet of the shut-off valve of the air cylinder unit through a union connector. The air outlet end of the air inlet pipe is connected to the air inlet end of multiple sets of T-type three-way ball valves. The air outlet end of the T-type three-way ball valves is connected to the air outlet clamp connector through the air outlet pipe.

[0007] The pressure testing port of the air cylinder body is connected to a safety valve, a pressure switch, and a shock-resistant pressure gauge respectively through a three-way cock valve. An installation platform is provided on the front side of the air cylinder body, and a pressure switch and a shock-resistant pressure gauge are installed on the installation platform.

[0008] The number of air outlet pipes is five, and there is an operation and maintenance space of not less than 30mm between the five air outlet pipes.

[0009] The T-type three-way ball valve is made of DN15 stainless steel. The number of T-type three-way ball valves is equal to the number of air outlet pipes. A corresponding ship quick-closing valve actuator is installed on the T-type three-way ball valve, and an indicator plate is installed on one side of the T-type three-way ball valve, which indicates the pipeline name and control function of the corresponding quick-closing valve.

[0010] The end of the air inlet pipe is equipped with a manual emergency air supply interface, which is connected to the air outlet of the manual emergency marine air compressor for quick connection to the emergency air source.

[0011] The air cylinder unit and the wall-mounted control box unit both use quick-connect fittings for their air lines. The length of the lines is adapted to the actual installation distance in the ship's space, and the layout of the air lines avoids other equipment inside the ship.

[0012] A mounting base is fixedly installed on the rear side of the control box, and ear plates are symmetrically installed on the surface of the mounting base.

[0013] A limiting groove is provided on the rear side of the bottom of the mounting base. An installation lifting mechanism is provided at the bottom of the mounting base. The installation lifting mechanism includes a support base, a hydraulic cylinder, and a push base. A hydraulic cylinder is installed on the side surface of the support base. A lifting groove is provided on the side surface of the support base. The output end of the hydraulic cylinder is fixedly connected to the push base. The push base is fixedly connected to the bottom end of the lifting plate that is slidably arranged in the lifting groove. A sliding plate is fixedly connected to the top of the lifting plate. A limiting plate is fixedly connected to the top side of the sliding plate. The limiting plate engages with the limiting groove.

[0014] The limiting plate has a T-shaped cross-section when viewed from above, and the limiting groove has a T-shaped cross-section when viewed from above.

[0015] The support base is provided with a fixing platform at its bottom end, and the fixing platform has fixing holes on its surface.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows: The aforementioned split-type quick-closing valve system adopts a split system architecture of an air cylinder unit and a wall-mounted control box unit. The two core units are independently installed in different suitable locations in the confined space of the ship, breaking the space limitations of the integral valve box. It is better adapted to the installation requirements of confined spaces such as the SOS room and engine room auxiliary machinery area of ​​the ship, and solves the problem that the integral quick-closing valve box cannot be arranged in confined spaces.

[0018] The wall-mounted control box unit adopts a lightweight and compact design. The box body is made of thin sheet metal and has a back ear plate for wall mounting, which does not occupy floor space. The air cylinder unit is an independent vertical structure, which can be arranged in the corner of a small space to maximize space utilization. At the same time, the internal layered pipeline layout provides ample space for operation and maintenance, solving the problem of inconvenient maintenance of traditional miniaturized devices.

[0019] The air cylinder unit and the wall-mounted control box unit are connected by standardized quick-connect air lines. The length and layout of the lines can be flexibly adapted to the actual space. All components use national / ship standard standardized parts, and the materials and dimensions are precisely matched. While ensuring the system strength and sealing, lightweight design is achieved, reducing the ship's load.

[0020] It integrates dual gas source interfaces for both conventional and manual emergency gas supply. Under normal conditions, it is supplied by the ship's main air cylinder, and in emergency situations, it can be quickly connected to a manual emergency marine air compressor, ensuring a fast emergency response. At the same time, the air cylinder unit is equipped with complete pressure detection and safety protection components, realizing real-time pressure monitoring, overpressure safety relief, and low pressure alarm functions, thereby improving the system's operational stability and safety reliability.

[0021] The modular structure enables independent troubleshooting. When a single component of the air cylinder unit or control box unit fails, the corresponding unit can be disassembled for repair without overall disassembly, greatly improving maintenance efficiency. At the same time, the standardized quick-connect couplings and bolt fixing methods reduce the difficulty of maintenance operations and are suitable for the rapid maintenance needs in the confined space of ships.

[0022] It can be directly applied to various types of ships, such as 9,000-ton multipurpose vessels. The installation position and pipeline length of the two units can also be flexibly adjusted according to the size and layout requirements of the small space of different ships. It has strong versatility and wide applicability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0037] This embodiment is applied to the SOS compartment of a 9,000-ton multipurpose vessel. The SOS compartment is small and has dense equipment, making it impossible to install an integrated quick-closing valve box.

[0038] like Figure 1-10 As shown, the split-type quick-closing valve system includes an air cylinder unit and a wall-mounted control box unit. The air cylinder unit and the wall-mounted control box unit are connected by a quick-connect air pipeline. The two units are installed separately in different suitable locations in the confined space of the ship to adapt to the layout requirements of confined spaces such as the SOS room and the auxiliary machinery area of ​​the engine room.

[0039] The full name of the ship's SOS room is the ship's communication and distress alarm center, which is a professional space that performs a variety of communication functions, and sending distress signals (SOS is its historical symbol) is its core responsibility.

[0040] The air cylinder unit includes an air cylinder body 14, which is supported by a foot 15 at the bottom. The air cylinder body 14 is equipped with a shut-off check valve 10 at the air inlet end, which is connected to the air outlet of the ship's main air cylinder dryer.

The end of the air outlet pipe 5 passes through the control box body 1 and is fitted with an air outlet clamping connector 6. The air inlet pipe 11 is connected to the air outlet of the shut-off valve 19 of the air cylinder unit through a union connector 12. The air outlet end of the air inlet pipe 11 is connected to the air inlet end of multiple sets of T-type three-way ball valves 7. The air outlet end of the T-type three-way ball valves 7 is connected to the air outlet clamping connector 6 through the air outlet pipe 5.

[0041] The control box 1 of the wall-mounted control box unit is made of Q235A material plate with a t=3. A 40x40x6 Q235A ear plate 22 is welded to the back, and wall-mounting is achieved with bolts. Two ø27x3.0 20# seamless steel pipe inlet pipes 11 are installed at the air inlet end of the box. The inlet pipes 11 are connected to the air outlet of the air cylinder unit's shut-off valve 19 via two M36x2 internal thread Q235A unions 12. The air outlet end of the inlet pipes 11 is connected to five sets of DN15 stainless steel T-type three-way ball valves 7. The air outlet end of each set of T-type three-way ball valves 7 is connected to one ø22x3.0 20# seamless steel pipe outlet pipe 5. The end of the outlet pipe 5 is equipped with a GB / T... Model 3737-2008 external clamp ø10 steel vent fitting 6; a ø48x4.5 20# seamless steel main vent pipe 8 is installed on the side of the control box 1, which is connected to the ship's quick-closing valve actuator; MS308-4 model combination door lock and CRT-S4-05 model plexiglass door glass are installed at the cabinet door of the box, and CRT-S4-03 model copper indicator 4 is installed next to each group of T-type three-way ball valves 7, indicating the pipeline name and control function of the corresponding quick-closing valve.

[0042] The control system is divided into an air cylinder unit and a wall-mounted control box unit. The air cylinder unit is located in the corner of the SOS room and is fixed to the ground by the base 15. The wall-mounted control box unit is wall-mounted on the wall of the SOS room by the rear ear plate 22, without occupying floor space. The horizontal distance between the two units is 1.2m, and they are connected by quick-connect air pipelines. The pipeline path avoids other equipment in the SOS room.

[0043] The pressure testing port of the air cylinder body 14 is connected to the safety valve 16, the pressure switch, and the shock-resistant pressure gauge 18 through a three-way cock valve 20. A mounting platform 17 is provided on the front side of the air cylinder body 14, and a pressure switch and a shock-resistant pressure gauge 18 are installed on the mounting platform 17.

[0044] The air cylinder body 14 is made of Q345R material with a diameter of ø273×6. A GB596-83 B40015 bronze check valve 10 is installed at the air inlet, connecting to the outlet of the ship's main air cylinder dryer to achieve unidirectional air intake from the main air source. An A0.03-0.7-02 copper three-way cock valve 20 is installed at the pressure testing port of the air cylinder body 14. The three ports of the three-way cock valve 20 are respectively connected to an HS-SF-R010 2Cr13 safety valve 16, a YWK-50-C pressure switch (range 0~1.0MPa), and a YC-100T-N shock-resistant pressure gauge 18 (range 0~1.6MPa) to achieve pressure detection, safe pressure relief, and low-pressure alarm. A GB595-83 standard is installed at the air outlet of the air cylinder body 14. The B40015 model bronze shut-off valve 19 serves as the main gas circuit switch, and is mounted on the bottom with an A0.03-0.7-03 model Q235 foot 15 to secure the unit.

[0045] The number of base feet 15 is three, and the three base feet 15 are distributed in a ring at the bottom of the air bottle body 14 to achieve independent fixation of the air bottle unit.

[0046] There are five air outlet pipes 5, and there is an operation and maintenance space of not less than 30mm between the five air outlet pipes 5.

[0047] The T-type three-way ball valve 7 is made of DN15 stainless steel. The number of T-type three-way ball valves 7 is equal to that of the air outlet pipe 5. A corresponding ship quick-closing valve actuator is set on the T-type three-way ball valve 7, and an indicator plate 4 is set on one side of the T-type three-way ball valve 7. The indicator plate 4 indicates the pipeline name and control function of the corresponding quick-closing valve.

[0048] The end of the air inlet pipe 11 is equipped with a manual emergency air supply interface, which is connected to the air outlet of the manual emergency marine air compressor 13 (HW-2A model) for quick connection to the emergency air source.

[0049] The air cylinder unit and the wall-mounted control box unit both use quick-connect couplings for their air lines. The length of the lines is adapted to the actual installation distance in the ship's space, and the layout of the air lines avoids other equipment in the ship's confined space.

[0050] During normal operation, the high-pressure gas from the ship's main air cylinder dryer enters the air cylinder body 14 through the shut-off check valve 10. The pressure switch and the shock-resistant pressure gauge 18 monitor the pressure in real time. When the pressure exceeds 1.0 MPa, the safety valve 16 automatically releases pressure. When the pressure is lower than 0.4 MPa, the pressure switch triggers an alarm. The high-pressure gas enters the wall-mounted control box unit through the shut-off valve 19 and the quick-connect gas pipeline. By operating different T-type three-way ball valves 7, the on / off control of the corresponding ship's quick-closing valve actuator is realized.

[0051] When the system malfunctions, the gas circuit switch of the corresponding unit can be turned off individually, the quick-connect gas circuit line can be disassembled, and the air cylinder unit or wall-mounted control box unit can be repaired independently. The 30mm operating space reserved in the layered layout of the box can realize the quick operation of valves and component replacement.

[0052] A mounting base 21 is fixedly installed on the rear side of the control box 1, and ear plates 22 are symmetrically installed on the surface of the mounting base 21 to realize the wall-mounted installation of the control box unit.

The limiting plate 237 is engaged with the limiting groove 211.

[0054] During the installation of the control box 1, the support base 231 is fixed, the control box 1 is placed on top of the slide plate 236, the limiting groove 211 of the mounting base 21 engages with the limiting plate 237, and then the hydraulic cylinder 232 pushes the fixedly connected push base 233 to move upward. The push base 233 pushes the lifting plate 234 fixedly installed on the bottom side surface to move, and the lifting plate 234 in turn pushes the slide plate 236 to rise and fall, adjusting the installation and adaptation height of the control box 1, reducing the need for multiple people to participate, facilitating fewer people to work in small spaces, and improving work efficiency.

[0055] The limiting plate 237 has a T-shaped cross-section when viewed from above, and the limiting groove 211 has a T-shaped cross-section when viewed from above.

[0056] The support base 231 is provided with a fixing platform at its bottom end, and the surface of the fixing platform is provided with fixing holes.

The pressure switch of the air cylinder unit is model YWK-50-C with a range of 0~1.0MPa, and the shock-resistant pressure gauge 18 is model YC-100T-N with a range of 0~1.6MPa. When the pressure inside the air cylinder body 14 is lower than 0.4MPa, the pressure switch triggers an alarm signal.

[0058] The ear plate 22 of the wall-mounted control box unit is made of Q235A material with dimensions of 40x40x6, and there is one set. The box body is fixed to the wall / equipment bracket in the narrow space of the ship through the ear plate 22.
