Description
Technical Field
[0001] The utility model relates to the technical field of check valves, in particular to a novel low-temperature resistant marine check valve. Background Art
[0002] Marine check valve, also known as one-way valve or non-return valve, is a valve used in ship piping systems. It is mainly used to prevent the reverse flow of fluid and ensure the normal operation of the ship piping system. Check valves are used in many key systems such as ship propulsion systems, fuel systems, and lubricating oil systems.
[0003] Since marine check valves contain fluid inside, when the external ambient temperature is low, the fluid inside the valve body is affected by external environmental factors and is prone to freezing, causing the fluid to be difficult to flow and the pipeline to be blocked, thus affecting the operation of subsequent equipment. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a novel low-temperature resistant marine check valve.
[0005] The utility model is implemented by the following technical scheme: a novel low-temperature resistant marine check valve, comprising a tool box, a check valve body is fixedly connected to the middle of the bottom wall of the tool box, an assembly plate is fixedly connected to the top of the tool box, a preset groove is opened on the lower surface of the assembly plate, and a heating component is fixedly connected to the inside of the preset groove;
[0006] The heating component includes a fan frame, and positioning bolts are arranged at the four corners of the surface of the fan frame. The fan frame is fixedly installed on the inner wall of the preset groove by the positioning bolts. An auxiliary fan is arranged inside the fan frame, and the bottoms of the inner walls on both sides of the preset groove are fixedly connected with electric heating wires.
[0007] Through the above technical solution, the fan frame is installed by positioning bolts, which is convenient for personnel to disassemble it later and clean and maintain the auxiliary fan. When the auxiliary fan rotates, the generated wind passes through the heated heating wire and becomes hot air to heat the surface of the check valve body, thereby preventing the liquid inside the check valve body from being affected by the environment in cold weather and having difficulty flowing inside the pipe, thereby affecting subsequent work. Combined with the insulation layer of the inner wall, heat loss can be reduced to prevent the fluid in the valve body from freezing. In addition, in hot weather, the heating wire is not heated. By starting the auxiliary fan to increase air circulation, it helps to take away the heat on the valve body, reduce the valve body temperature, improve applicability, and extend the service life of the valve body.
[0008] As a further improvement of the above solution, one end of the check valve body is fixedly connected to a connecting pipe, and one side of the outer surface of the tooling box is fixedly connected to an extension block.
[0009] Through the above technical solution, the check valve body can transport the internal liquid to the corresponding equipment through the connecting pipeline, and the setting of the extension block can improve the stability of the support seat when it is fixed.
[0010] As a further improvement of the above solution, the upper surface of the stretching block is fixedly connected to a support seat, and the connecting pipe is inserted into the interior of the support seat.
[0011] Through the above technical solution, the support seat can support and fix the extended connecting pipe to prevent the connecting pipe from shifting and shaking when the liquid flows, thereby affecting the normal work of subsequent personnel.
[0012] As a further improvement of the above solution, first sliding grooves are provided on both sides of the inner bottom wall of the tooling box, and a first sliding block is slidably connected inside the first sliding groove.
[0013] Through the above technical solution, the first sliding block slides inside the first sliding groove, which can limit the connection structure and prevent it from deviating from the movement track during the movement.
[0014] As a further improvement of the above solution, a protective door is fixedly connected to one side of the first sliding block, and the protective door is slidably connected to the interior of the tooling box through the first sliding block.
[0015] Through the above technical solution, the provision of the protective door can improve the protection of the check valve body, prevent the check valve body from being exposed to the outside and susceptible to collision and impact by external objects, and reduce the subsequent maintenance cost of the check valve body by personnel.
[0016] As a further improvement of the above solution, an operating handle is fixedly connected to one side of the front of the protective door, and a transparent observation window is opened on the other side of the front of the protective door.
[0017] Through the above technical solution, personnel can quickly disassemble and assemble the protective door by operating the handle, and the transparent observation window allows personnel to observe the working status of the internal check valve body from the outside. When a fault occurs, personnel can discover and perform maintenance in time.
[0018] As a further improvement of the above scheme, a hole for auxiliary fan air intake is opened in the middle of the upper surface of the assembly plate, a filter is fixedly connected to the surface of the hole, and an insulation layer is fixedly connected to the inner wall of the tooling box, and the material of the insulation layer is polyurethane foam plastic.
[0019] Through the above technical scheme, polyurethane foam plastic is a high molecular organic polymer with a very high closed-cell rate and a low thermal conductivity, excellent thermal insulation performance, and reduced heat loss.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] The utility model provides a heating component, and the fan frame is installed by positioning bolts, which is convenient for personnel to disassemble it later and clean and maintain the auxiliary fan. When the auxiliary fan rotates, the wind generated is heated by the electric heating wire and becomes hot wind to heat the surface of the check valve body, thereby preventing the liquid inside the check valve body from being affected by the environment in cold weather and having difficulty in flowing inside the pipeline, thereby affecting subsequent work. Combined with the thermal insulation layer of the inner wall, heat loss can be reduced, freezing of the fluid in the valve body can be prevented, and the working performance of the check valve body in cold environments can be improved.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0030] Example:
[0031] Please combine Figure 1-5 A novel low-temperature resistant marine check valve of this embodiment comprises a tool box 1, a check valve body 2 is fixedly connected to the middle of the bottom wall of the tool box 1, an assembly plate 3 is fixedly connected to the top of the tool box 1, a preset groove is opened on the lower surface of the assembly plate 3, and a heating component 4 is fixedly connected to the inside of the preset groove;
[0032] The heating component 4 includes a fan frame 401, and positioning bolts 402 are arranged at the four corners of the surface of the fan frame 401. The fan frame 401 is fixedly installed on the inner wall of the preset groove by the positioning bolts 402. An auxiliary fan 403 is arranged inside the fan frame 401. The bottom of the inner wall on both sides of the preset groove is fixedly connected with a heating wire 404. The fan frame 401 is installed by the positioning bolts 402, which is convenient for personnel to disassemble it later and clean and maintain the auxiliary fan 403. When the auxiliary fan 403 rotates, the wind generated passes through the heating wire 403. The heated heating wire 404 turns into hot air to heat the surface of the check valve body 2, so as to prevent the liquid inside the check valve body 2 from being affected by the environment in cold weather and having difficulty in flowing inside the pipe, thereby affecting subsequent work. In conjunction with the insulation layer 14 on the inner wall, heat loss can be reduced to prevent the fluid in the valve body from freezing. In hot weather, the heating wire 404 is not heated, and the auxiliary fan 403 is started to increase air circulation, which helps to take away the heat on the valve body, reduce the temperature of the valve body, improve applicability, and extend the service life of the valve body.
[0033] One end of the check valve body 2 is fixedly connected to a connecting pipe 5, and one side of the outer surface of the tooling box 1 is fixedly connected to an extension block 6. The check valve body 2 can transport the internal liquid to the corresponding equipment through the connecting pipe 5. The setting of the extension block 6 can improve the stability of the support seat 7 when it is fixed.
[0034] The upper surface of the extension block 6 is fixedly connected with a support seat 7, and the connecting pipe 5 is inserted into the inside of the support seat 7. The support seat 7 can support and fix the extended connecting pipe 5 to prevent the connecting pipe 5 from shifting and shaking when the liquid flows, affecting the normal work of subsequent personnel.
[0035] A first slide groove 8 is provided on both sides of the inner bottom wall of the tooling box 1, and a first slider 9 is slidably connected inside the first slide groove 8. The first slider 9 slides inside the first slide groove 8 to limit the connection structure to avoid deviation from the motion trajectory during movement.
[0036] A protective door 10 is fixedly connected to one side of the first slider 9, and the protective door 10 is slidably connected to the interior of the tooling box 1 through the first slider 9. The provision of the protective door 10 can improve the protection of the check valve body 2, avoid the check valve body 2 being exposed to the outside and susceptible to collision and impact by external objects, and reduce the subsequent maintenance cost of the check valve body 2 by personnel.
[0037] An operating handle 11 is fixedly connected to one side of the front of the protective door 10, and a transparent observation window 12 is provided on the other side of the front of the protective door 10.

When a fault occurs, personnel can discover and perform maintenance in time.
[0038] A hole is provided in the middle of the upper surface of the assembly plate 3 for air intake by the auxiliary fan 403, and a filter screen 13 is fixedly connected to the surface of the hole. An insulation layer 14 is fixedly connected to the inner wall of the tooling box 1. The material of the insulation layer 14 is polyurethane foam plastic. Polyurethane foam plastic is a high molecular organic polymer with a very high closed-cell rate and a low thermal conductivity coefficient, excellent thermal insulation performance, and reduced heat loss.
[0039] The implementation principle of a new type of low-temperature resistant marine check valve in the embodiment of the present application is as follows: personnel install the fan frame 401 through the positioning bolts 402, which is convenient for personnel to disassemble it later and clean and maintain the auxiliary fan 403. When the auxiliary fan 403 rotates, the wind generated passes through the heated electric heating wire 404 and becomes hot wind to heat the surface of the check valve body 2, so as to avoid the liquid inside the check valve body 2 being affected by the environment in cold weather and difficult to circulate inside the pipeline, thereby affecting subsequent work. In conjunction with the insulation layer 14 of the inner wall, polyurethane foam plastic is a high molecular organic polymer. The compound has a high closed-pore rate and a low thermal conductivity, and has excellent thermal insulation performance, which can reduce heat loss and prevent the fluid in the valve body from freezing. In hot weather, the electric heating wire 404 is not heated. By starting the auxiliary fan 403 to increase air circulation, it is helpful to take away the heat on the valve body, reduce the valve body temperature, improve applicability, and extend the service life of the valve body. Personnel can quickly disassemble and assemble the protective door 10 through the operating handle 11, and the transparent observation window 12 is convenient for personnel to observe the working status of the internal check valve body 2 from the outside. When a fault occurs, personnel can discover and perform maintenance in time.
