Description

Marine fluid control valve device

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

In general, in the case of a ship, various pipes and various valves for controlling fluid in the pipe are used for their own function.

In the case of manual configuration of the valves, an operation handle is included, and the opening/closing is determined according to the operation of the operation handle.

In addition, a separate actuator may be provided, and the opening and closing may be controlled according to the operation of the actuator, and the actuator may be implemented manually or automatically.

Various configurations have been proposed and used for the marine valve as described above. For example, in the case of a manual valve, there is provided a ship valve provided with a handle and a pipe flange according to Public Utility Model No. 2014-0003491, comprising: a fixing plate fixed to the pipe flange by bolt and nut fastening to have a connection hole; A flexible wire inserted into the connection hole between the handle and the fixing plate; U-bolts fitted to surround both ends of the wire inserted into the handle and the connection hole; A crimping plate that is fitted to the bolts on both sides of the U-bolt to compress the wire so that the wire does not come off; A configuration is disclosed including a nut that is fastened to each of the bolts on both sides of the U-bolt to compress the pressing plate.

In addition, Korean Patent Application Publication No. 2003-0038606 may be mentioned as a configuration including a separate actuator. The above patent constitutes a manual remote valve opening and closing device consisting of a valve installed in a pipe inside a ship, an actuator that opens and closes the valve, and a manual hydraulic pump connected to the actuator by a hydraulic line. By configuring the interlocking member with a rack and a pinion, the hydraulic pressure required to open and close the valve is always applied evenly, making it easier to operate the manual hydraulic pump, as well as reducing the stroke distance of the two-way piston, greatly reducing the volume of the actuator. It can be installed easily in a narrow space inside the ship. Also, the assembly gap between the inner circumferential surface of the cylinder hole formed in the cylinder block of the manual hydraulic pump and the outer circumferential surface of the piston inserted into the cylinder hole is formed to be 0.01 to 0.015 mm, There is disclosed a manual remote valve opening/closing device for a ship that is configured to be sealed only with an oil film of hydraulic oil without requiring any packing inserted between a cylinder hole and a piston of a conventional manual hydraulic pump, thereby further improving durability.

On the other hand, in the case of a marine valve equipped with an actuator, since the valve is opened and closed by a linear actuator, the linear actuator is usually arranged vertically, and the valve is closed by driving the actuator.

However, in the case of a ship, especially a deck, since the valve is installed in a state in which various pipes are arranged, space restrictions arise. In particular, when a large number of pipes are arranged vertically, the height of the valve becomes an important factor in the installation condition, and in the case of a valve in which the actuator is arranged vertically as described above, it is impossible to install it. There was this.

The present invention was conceived to overcome the disadvantages of the prior art as described above, and the actuator is arranged horizontally and the posture can be rotated, thereby providing a marine fluid control valve device that can be conveniently installed even in a location with space constraints. The purpose is to provide.

In order to achieve the above object, the present invention provides a fluid control valve device for a ship that is mounted on a pipe installed in a ship and controls the amount of fluid flowing therein, wherein the flow formed in the inlet, the outlet, the barrier wall and the barrier wall A valve assembly including a valve body including a hole, a stem vertically transferred according to a coupling hole formed at an upper end of the valve body, and a seat attached to an end of the stem to contact the flow hole; Attached to a base rotatably coupled to the top of the valve assembly, two vertical portions formed vertically on the side of the base, an actuator horizontally coupled to the vertical portion, and a rod horizontally transported between the two vertical portions An actuator assembly including a cam member to be formed; A connecting member coupled to the end of the stem so as to rotate in a vertical axis direction; And a pin inserted into an inclined groove formed in the cam member and coupled to the connecting member.

Preferably, it is configured in a'c' shape of the connecting member, and the cam member is located between the connecting members.

More preferably, a support portion is formed at an end of the cam member, and the support portion is inserted into a hole formed in a vertical portion opposite the vertical portion on which the actuator is mounted.

More preferably, the base further comprises a fixing portion for fixing the actuator assembly to the valve assembly.

More preferably, the pin is characterized in that it also includes a roller formed in a portion in contact with the inclined groove.

The marine fluid control valve device according to the present invention is characterized in that the actuator is rotatably coupled horizontally to the top of the valve assembly, and the valve stem that moves vertically is driven by a cam mechanism, thereby minimizing the height of the entire valve device. In addition, since the actuator is rotatable with respect to the valve body and can be fixed through a separate fastener after positioning the actuator at an optimal position, there is an effect of increasing the installation freedom of the valve device.
