Description

Fluid Control Valves for Ships

technical field

The present invention relates to a fluid control valve for ships, and more particularly, to a fluid control valve for ships with improved space efficiency.

Background technique

Generally, in the case of ships, various lines and various valves for regulating the fluid of said lines are used in order to achieve the inherent function.

When the valve is configured manually, it is realized in a form in which an operation handle is included, and opening and closing are determined according to the operation of the operation handle.

In addition, it can be realized in a form in which a separate actuator is included and the opening and closing are controlled according to the operation of the actuator, which is realized manually or automatically.

Said valve for ships proposes various structures and is used. For example, in the case of a manual valve, there is a valve for a ship having a handle and a pipe flange, and a structure is disclosed in which a fixing plate is fastened to the pipe flange by bolts and nuts, so as to have a connection holes; flexible wires inserted into the connection holes of the handle and the fixing plate; U bolts inserted in the form of wrapping both ends of the wires inserted into the handle and the connection holes; The pressing plate is inserted into the bolt parts on both sides of the U-bolt to press the wire in a form that does not come out; the nut is respectively fastened to the bolt parts on both sides of the U-bolt to press the pressing plate.

In addition, as a structure with another actuator, there is a manual remote valve opening and closing device including: a valve installed on a pipeline inside a ship; an actuator that opens and closes the valve; a manual hydraulic pump, It is connected to the actuator through hydraulic lines, and is composed of a rack and a pinion to form a linkage part, which makes the bidirectional piston of the actuator and the valve shaft interlock with each other, thereby making the valve open and close. The required hydraulic pressure is always applied evenly, which not only makes the operation of the manual hydraulic pump easier, but also reduces the stroke distance of the two-way piston, which can greatly reduce the volume of the actuator, so it can also be easily used in narrow spaces in the ship. Install and make the assembly gap between the inner peripheral surface of the cylinder hole formed by the cylinder module of the manual hydraulic pump and the outer peripheral surface of the piston into which the cylinder hole is inserted is 0.01 to 0.015mm, so that no packaging is required, and only hydraulic oil is used. Therefore, the package inserted between the cylinder hole and the piston of the existing manual hydraulic pump is completely unnecessary, so that the durability is further improved.

Also, in the case of a valve for a ship having an actuator, the valve is opened and closed by a linear actuator, so the linear actuator is usually arranged vertically, and the valve is opened and closed by the driving of the actuator.

However, in a ship, especially in a deck, since the valve is installed in a state of various pipeline arrangements, there is a space restriction. In particular, when a plurality of pipelines are arranged vertically, the height of the valve is an important factor in the installation conditions, so the disadvantage is that, as mentioned above, for the valve with the actuator arranged vertically, the installation cannot be realized and Occasionally, installations in other locations have occurred.

detailed description

Hereinafter, some embodiments of the present invention will be described in detail with reference to the exemplary drawings. Elements in each drawing are denoted by reference numerals, and it should be noted that the same elements are used as much as possible even if they are indicated in other drawings. In addition, when describing the embodiments of the present invention, detailed descriptions of related well-known structures or functions are omitted if it is judged that they do not obstruct the understanding of the present invention.

In addition, when describing the constituent elements of the embodiments of the present invention, terms such as first, second, A, B, (a), (b) may be used. Such terms are only used to distinguish their constituent elements from other constituent elements, and the nature or order or sequence of the corresponding constituent elements are not limited by the terms. When it is described that a certain component is connected, combined or coupled with another component, it should be understood that the component can be directly connected or coupled with another component, but it can also be understood that each component can be connected , combined or coupled with yet another constituent element.

As shown in FIG. 1 , a fluid control valve 100 for a ship according to the present invention includes: a valve assembly 10; The assembly 10 is rotatably coupled, and the actuator assembly 50 is rotatable relative to the valve assembly 10 , and can be fixed to the valve assembly 10 by the fixing portion 90 if necessary.

As shown in FIG. 2 , first, the valve assembly 10 includes a valve main body 15 , the valve main body 15 is additionally formed with an inflow port 11 and an outflow port 12 , and a blocking wall 13 is formed inside, including a blocking wall 13 formed on the blocking wall. Flow hole 14 of wall 13 .

In addition, it includes: a sheet 20, which is moved up and down to open and seal the flow hole 14; a valve stem 22, which is in the shape of a circular stick, combined with the upper end of the sheet 20, and formed on the The combination hole 21 on the upper end of the valve body 15 is combined.

Thereby, when the valve rod 22 is moved up and down, the opening/closing of the valve assembly 10 is determined. For example, if the valve stem 22 is moved upward, the sheet 20 opens the flow hole 14 so that the inflow port 11 and the outflow port 12 are communicated. Conversely, if the valve stem is moved downward 22, the flow hole 14 is finally closed, thereby stopping the movement of the fluid.

At this time, the amount of fluid flowing between the inflow port 11 and the outflow port 12 can be determined based on the gap between the sheet 20 and the flow hole 14 .

In addition, as shown in FIG. 3 , a connecting member 30 is coupled to the upper end of the valve rod 22 , and the connecting member 30 is coupled to be rotatable in the longitudinal direction of the valve rod 22 .

The connecting member 30 is formed as

In the shape of a letter, the pin 31 is combined with the hole formed at the end.

In addition, as shown in FIG. 4 , the actuator assembly 50 includes: a base 60 rotatably coupled to the upper end of the valve body 15 ; an actuator 70 coupled to the base 60 and arranged horizontally; a cam member 80 , which is attached to the rod end of the actuator 70 .

The base 60 includes: a joint part 61 , which is combined with the upper end of the valve body 15 ; and a through part 62 , which is formed in the center of the joint part 61 .

The through portion 62 is formed to extend toward the upper end of the valve stem 22 .

In addition, the coupling portion 61 is formed to accommodate the valve body 15 , and a fixing portion 90 for fixing the base 60 is coupled to one surface of the coupling portion 61 , thereby stopping the connection to the base 60 when necessary. rotation.

After the combination portion 61 is combined with the valve body 15, in order to prevent separation, a suitable short sill can be formed.

In addition, two vertical parts 65 are formed on the side of the base 60 , so that the actuator 70 is fixed to the vertical parts 65 , and the rod 71 of the actuator 70 is formed by the vertical parts 65 . The holes are arranged between the vertical portions 65 .

Here, the actuator 70 is formed as a common structure, and is composed of a hydraulic cylinder and a piston moved inside the hydraulic cylinder, and the rod 71 is formed so as to be attached to the piston and to be driven by hydraulic pressure on both sides of the piston. Adjust the stroke.

Further, the distal end of the rod 71 is coupled with a cam member 80 , and the support portion 81 of the cam member 80 is coupled with a hole formed in the vertical portion 65 .

In addition, an inclined groove 82 is formed in the center of the cam member 80 , and as shown in FIG.

Thus, when the rod 71 of the actuator 70 is moved to the left and right (by supplying hydraulic pressure to the air cylinder), the pin 81 is moved up and down by the action of the inclined groove 82, and finally the sheet 20 is moved up and down. , so as to open and close the valve assembly 10 .

The inclined groove 32 limits the vertical movement of the valve stem 22 through the horizontal movement of the actuator 70. In the case of an inclined linear shape, the movement of the actuator 70 and the valve stem 22 is realized in proportion, and if necessary, the As a curve, it can be configured to transfer at a relatively high speed in the initial stage, and finally transfer at a relatively slow speed.

In addition, a roller is attached to the portion of the pin 81 that is in contact with the inclined groove 82, so that the friction between the inclined groove 82 and the pin 81 can be reduced. width so that only one side of the roller is in contact. In other words, it is preferable to make the width of the inclined groove 82 slightly larger than the diameter of the roller, so that when the valve stem 22 descends, it contacts the upper surface of the inclined groove 82, and when it ascends, it contacts the lower surface of the inclined groove 82,

In addition, since the actuator assembly 50 is configured to rotate relative to the valve assembly 10, after installation of necessary pipelines, the actuator assembly 50 is rotated to be installed in the most suitable After the position of the actuator assembly 50 is fixed to the valve assembly 10 by the fixing portion 90 , the advantage is that interference by the actuator assembly 50 can be prevented.

Here, most preferably, the fixing portion 90 is formed of a bolt, so that the actuator assembly 50 can be fixed to the valve assembly 10 by rotation, but other types of fixing members can be used to achieve it, If necessary, it can be composed of more than one. In addition, the valve body 15 to which the fixing member 90 is fixed forms a groove, so that the actuator assembly 50 and the valve assembly 10 are not separated by the action of the fixing member 90 .

Of course, the valve assembly 10 can also be operated without fixing the actuator assembly 50 .

Although the specific preferred embodiments of the present invention have been shown and described above, the present invention is not limited to these embodiments, and those with ordinary knowledge within the technical scope of the present invention can claim the technology of the present invention without departing from the scope of the claims. The embodiments of various forms that can be implemented are all included within the scope of the idea.
