Description

Technical Field

[0001] The utility model relates to the field of valves, and particularly relates to a titanium alloy valve for ships with double seals. Background Art

[0002] A valve is a device used to control the flow of a medium between a pipeline and a device or between pipelines. Common valves include butterfly valves, ball valves, etc. A titanium alloy valve is a valve mainly made of titanium alloy and is widely used in the fields of ships and heavy industries.

[0003] However, the existing titanium alloy valves for ships have the problem of poor sealing performance during use. Traditional butterfly valves all have a single valve plate. When the single valve plate is worn or accidentally damaged, the valve will leak. Moreover, the sealing strength of the single valve plate is poor, which is not conducive to use in an environment where a ship shakes frequently.

[0004] Therefore, this case proposes a titanium alloy valve for ships with double seals to solve the above technical problems. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a titanium alloy valve for ships with double seals, which can effectively solve the technical problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A titanium alloy valve for ships with double seals includes a housing. Connecting pipes are installed at both ends of the housing. The two connecting pipes are respectively a medium input pipe and a medium output pipe. A protective cover is fixedly installed on the upper part of the housing, and a handle is rotatably connected to the upper part of the protective cover. A first valve plate and a second valve plate are rotatably installed inside the housing. The tops of the first valve plate and the second valve plate are respectively fixedly connected with a first driven gear and a second driven gear. The bottom end of the handle is fixedly connected with a driving gear, and the driving gear is meshed with the first driven gear and the second driven gear.

[0008] As a further solution of the utility model, a locking assembly is provided between the protective cover and the handle. The locking assembly includes a fixed gear and a fixed seat. The fixed gear is fixedly installed on the upper part of the protective cover below the handle. The fixed seat is fixedly installed on the upper part of the handle. A screw rod is threadedly connected inside the fixed seat, and the front end of the screw rod is rotatably connected with a sliding rod inside the fixed seat. One end of the sliding rod is fixedly installed with a clamping seat, and the clamping seat is meshed with the fixed gear.

[0009] As a further solution of the utility model, the sliding rod is arranged in a "C" shape, and the connection part between the screw rod and the sliding rod is arranged in a "convex" shape.

[0010] As a further solution of the utility model, ear seats are fixedly installed on the front and rear of the shell, and two installation grooves are provided on the upper surfaces of the two ear seats.

[0011] As a further solution of the utility model, the connecting pipe consists of a pipe body, an external hexagonal seat, and a flange. The external hexagonal seat is fixedly installed on the outside of the pipe body, the flange is fixedly installed on one end of the pipe body, the flange is connected to the shell by six bolts, and an external thread is provided on the outer surface of the pipe body near the other end.

[0012] The beneficial effects of the utility model are as follows:

[0013] By setting the first valve plate, the second valve plate, the first driven gear, the second driven gear and the driving gear, the first valve plate and the second valve plate can be controlled to rotate simultaneously by the handle. On the one hand, the two valve plates realize double sealing of the valve, increase the sealing effect and reduce the leakage problem. On the other hand, the operation only requires turning one handle, which is convenient and quick.

[0014] By setting a locking assembly, the handle can be locked. After the handle is locked, the first valve plate and the second valve plate cannot rotate, thereby avoiding the problem of the valve plate rotating due to the shaking of the ship and the impact of the medium, and improving the stability of the valve.

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1-Figure 6 shown, a titanium alloy valve for ships with double seals includes a housing 1. Connecting pipes 2 are installed at both ends of the housing 1. The two connecting pipes 2 are respectively a medium input pipe and a medium output pipe. A protective cover 3 is fixedly installed on the upper part of the housing 1, and a handle 4 is rotatably connected to the upper part of the protective cover 3. A first valve plate 5 and a second valve plate 6 are rotatably installed inside the housing 1. The top ends of the first valve plate 5 and the second valve plate 6 are respectively fixedly connected with a first driven gear 7 and a second driven gear 8. The bottom end of the handle 4 is fixedly connected with a driving gear 9, and the driving gear 9 is meshed with the first driven gear 7 and the second driven gear 8.

[0024] In this embodiment, a locking assembly 10 is provided between the protective cover 3 and the handle 4. The locking assembly 10 includes a fixed gear 11 and a fixed seat 12. The fixed gear 11 is fixedly installed on the upper part of the protective cover 3 below the handle 4. The fixed seat 12 is fixedly installed on the upper part of the handle 4. A screw 13 is threadedly connected inside the fixed seat 12, and the front end of the screw 13 is rotatably connected with a slide bar 14 inside the fixed seat 12. One end of the slide bar 14 is fixedly installed with a clamping seat 15, and the clamping seat 15 is meshed with the fixed gear 11;

[0025] The locking assembly 10 can lock the position of the handle 4, and then lock the position of the driving gear 9, thereby avoiding the phenomenon that the first valve plate 5 and the second valve plate 6 rotate automatically due to the shaking of the ship and the impact of the medium.

[0026] In this embodiment, the slide bar 14 is arranged in a "C" shape, and the connection part between the screw 13 and the slide bar 14 is arranged in a "convex" shape;

[0027] The connection part between the screw 13 and the slide bar 14 is arranged in a "convex" shape, so the slide bar 14 and the screw 13 can rotate and will not separate.

[0028] In this embodiment, ear seats are fixedly installed at the front and rear parts of the housing 1, and two installation grooves are respectively opened on the upper surfaces of the two ear seats;

[0029] By passing an external installation part through the installation groove and fixing it on the platform, the housing 1 can be fixed through the two ear seats.

[0030] In this embodiment, the connecting pipe 2 is composed of a pipe body, an external hexagonal seat, and a flange. The external hexagonal seat is fixedly mounted on the outside of the pipe body, the flange is fixedly mounted on one end of the pipe body, the flange is connected to the housing 1 by six bolts, and an external thread is provided on the outer surface of the pipe body near the other end.

[0031] The external thread can be conveniently connected to an external pipe, and the external hexagonal seat can conveniently fix the position of the connecting pipe 2 when rotating to connect the external pipe.

[0032] It should be noted that the utility model is a double-sealed titanium alloy valve for ships. When in use, the housing 1 is installed on a platform or ship equipment using an external mounting member, and then the medium input and output pipelines are respectively connected to the two connecting pipes 2, and the handle 4 is turned, and the handle 4 drives the driving gear 9 to rotate, and the driving gear 9 drives the first driven gear 7 and the second driven gear 8 to rotate, thereby driving the first valve plate 5 and the second valve plate 6 to rotate, and the opening and closing of the valve can be controlled;

[0033] After adjusting the valve opening and closing, the screw rod 13 is rotated, and the screw rod 13 drives the slide rod 14 to move, thereby driving the clamping seat 15 to engage with the fixed gear 11. After engagement, the position of the handle 4 can be locked so that the handle 4 will not rotate.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
