Description

Flange type fluid valve

The present invention relates to a flange-type fluid valve, and more particularly to a valve having a flange, for controlling the opening and closing of the flow of the fluid flowing from one side to the other side.

Flanged fluid valves are usually made of bronze and are used for various mechanical parts, transformers, and the like. Figure 1 is a perspective view of a conventional flanged fluid valve, as shown, the valve 100 is formed with a flange (f) at the inlet and the outlet, respectively, these are flanges and packings respectively installed on the mechanical elements to be connected, etc. It is fastened with a special bolt through the bolt hole (110) in the state.

Taking the transformer as an example, the transformer needs a device for cooling the oil for the transformer, that is, a radiator, and the valve is used to open and close the flow of oil between the radiator and the transformer.

That is, the valve is closed when not in operation, such as when carrying a transformer, and opened when the transformer is operated.

By the way, this conventional flange-type hydraulic valve has the inconvenience of having to form a flange on both sides.

Referring to FIG. 2 by way of example, when the flange f1 is formed only on the transformer 120 side, the corresponding flange f2 must be installed to apply the valve 100 to the hose 130 which is the outlet side. There is discomfort.

In addition, since the flange (f) is formed on both sides, there is a disadvantage that the volume or weight of the valve itself is high.

In addition, since this valve is a valve for controlling the fluid, it is necessary to increase the airtightness, and especially in a part where a high temperature is generated such as a transformer, the airtightness may be weakened by the high temperature.

The present invention is devised to improve the problems of the conventional flanged fluid valve as described above, an object of the present invention is to provide a flange-type fluid valve that can be used without installing the flange on both sides.

Another object of the present invention is to provide a flanged fluid valve that can improve airtightness.

Still another object of the present invention is to provide a flanged fluid valve that can reduce volume and weight.

(Short description of symbols for main parts of drawing)

10: fluid valve 11, 12, 13: each passage

15: main body 19: connecting member

17: Handle 35a: O-ring

In order to achieve the above object, the present invention provides a main body including a first passage formed with a flange, a second passage formed with a bolt hole, and a third passage formed between the first passage and the second passage; Provided is a flanged fluid valve including an opening and closing to open and close the third passage to selectively open and close the fluid flowing between the first passage and the second passage.

Preferably the fluid valve is characterized in that the bronze or cast iron.

Preferably the fluid valve further comprises a handle for adjusting the opening and closing, and a connecting member for connecting between the handle and the fluid valve opening and closing, the connection portion between the connecting member and the third passage of the main body- A ring is installed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view of a fluid valve of bronze material according to the present invention, as shown, the fluid valve 10 corresponds to the first passage 11 and the first passage 11, the flange (f) is formed; It is based on the main body 15 provided in the side which is provided, and the 2nd path 12 in which the bolt hole was formed, and the 3rd path 13 provided between the said 1st path and the said 2nd path 12 is made. .

Handle portion 17 is provided on the third passage 13 side of the main body 15, a connecting member 19 is provided between the handle portion 17 and the third passage 13, the connection The member 19 and the handle 17 are connected by a first nut 21, and the connecting member 19 and the third passage 13 are connected by a second nut 22.

Referring to the partial exploded perspective view of FIG. 4, the connection member 19 is fastened to the lower opening / closing hole 25, and the lower side of the connecting member 19 is fastening for fastening to the opening / closing device 25. The shaft 23 is mounted. The opening and closing port 25 is a flow of fluid flowing between the first passage 11 and the second passage 12 while moving the third passage 13 up and down according to the rotation of the handle 17 of FIG. Will be opened and closed.

Also of note in the present invention is the sealing of the connecting member 19 and the third passage 13 of the main body 15, for this purpose an o-ring between the connecting member 19 and the third passage 13. It seals through (O-ring) 35a. The o-ring 35a is fitted to an end portion 19a of the lower side of the connecting member 19 and to an inner step 13a of the third passage.

The large diameter portion 19b of the connecting member 19 is caught by the inlet side of the third passage 13 and is fastened to the third passage 13 by the second nut 22.

Although only one embodiment has been described above, those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention. For example, this valve can be applied to all fluids such as water, oil, etc., and may be applied to valves of various materials.

However, it will be apparent from the appended claims that all such changes and modifications fall within the scope of the present invention.

As described above, in the present invention, only one flange is formed in the fluid passage. Therefore, there is an advantage of eliminating the inconvenience of having to form a flange on both mechanical elements connected to the fluid valve.

That is, for example, when the fluid valve 10 according to the present invention is applied to a transformer as shown in FIG. 5, only the transformer 120 is installed with a flange f1 and the flange 30 is not required to be installed at the hose 30 side. .

In addition, in the present invention, since the O-ring is used for sealing between the main body of the fluid valve and the connection member connected to the handle part and equipped with the opening and closing port, there is an advantage of improving the reliability of the fluid valve.
