Description

Angle Valve

The present invention relates to an angle valve, and more specifically, by configuring an adapter part, even if the body part detachably coupled to the adapter part is separated from the adapter part, external leakage of fluid is prevented by the blocking part, thereby preventing the fluid supply itself. This relates to an angle valve that allows maintenance of the valve without blocking it and can be easily applied to existing facilities.

A valve is a device that controls or changes the direction of fluid flow by changing or opening or closing a passage.

These valves are largely divided into a stop valve that opens and closes parallel to the flow direction of the fluid, a gate valve that opens and closes by blocking the fluid passage vertically with a valve disc, and the fluid flow is maintained in a straight line, It is divided into check valves, which allow fluid to flow in one direction and prevent it from flowing in the opposite direction.

The stop valve includes a globe valve that generally has a ball-shaped valve body, the center line of the inlet and outlet is on a straight line, and the fluid flow is S-shaped, and the inlet and outlet of the valve body An angle valve whose center line is at a right angle and the flow direction of the fluid changes at a right angle, and a Y-type valve (Y) where the center line of the inlet and outlet of the valve body is on a straight line, and the axis of the valve seat and the flow path of the outlet are at an acute angle. -globe valve) and needle valve where the valve disc is shaped like a needle to make it easy to control the flow rate.

Figure 1 is a diagram showing a conventional angle valve 90, which is disclosed in Korean Patent Publication No. 10-0972099 (July 16, 2010).

1, a water meter for measuring the amount of tap water used is installed in a water meter protection tank buried in the ground, and an angle valve 90 for controlling the flow of tap water is installed on one side of this water meter.

As shown in FIG. 1, the angle valve 90 has an inlet 911 through which fluid flows, and is formed at a right angle to the inlet 911 so that the fluid flowing in from the inlet 911 flows out. An outlet portion 913 and a center line parallel to the center line of the inlet portion 911 are formed on the other side of the inlet portion 911, and a female thread 9151 is formed on the inner peripheral surface and a male thread 9153 is formed on the outer peripheral surface. It has a body portion 91 including a formed connection portion 915.

In addition, the conventional angle valve 90 includes a handle portion 931 having a shape that can be turned by hand, and a male thread extending downward from the handle portion 931 and screwing into the female thread 9151. An elevation portion 933 formed with (9331), and a disk portion 935 formed at the bottom of the elevation portion 933 to prevent fluid flowing in from the inlet portion 911 from flowing into the outlet portion 913. ) is configured to include an adjustment unit 93.

And the conventional angle valve 90 includes a fastening washer 951 placed on the connection part 915, a fastening gasket 953 formed on the fastening washer 951 to prevent water leakage, and the connection part ( The fastening part 95 is composed of a fastening cover 955 having a female thread 9551 that screws into the male thread 9153 of 915).

This conventional angle valve 90 rotates the handle part 931 clockwise or counterclockwise to raise and lower the raising and lowering part 933, so that the disk part 935 is separated from the inlet part 911. It is controlled to block incoming fluid or adjust the amount of incoming fluid.

However, since the female thread 9151 of the connection portion 915 and the male thread 9331 of the elevating lowering portion 933 are submerged in tap water, foreign substances such as sand flowing in with tap water through the inlet portion 911 are immersed in the arm. Even if the handle part 931 is turned by being caught between the screw thread 9151 and the external screw thread 9331, a problem occurs in which the adjusting part 93 does not operate normally, or water leakage occurs due to wear of the disk part 935, etc. Breakdowns such as these occurred frequently.

When such a failure occurs, according to the conventional angle valve 90, the valve of the raw water pipe had to be closed to fundamentally block the inflow of fluid. In this case, raw water is not supplied to other areas where there is no problem during repair work, and There was a problem with water being cut off.

In addition, since the conventional angle valve 90 had a structure that made partial repair difficult, once a problem occurred in the angle valve 90, the entire angle valve 90 had to be replaced.

Accordingly, in the related industry, work can be performed even without blocking the supply of raw water during the repair of the angle valve 90, and partial repairs can also be easily performed, eliminating the problem of unnecessary complete replacement of the angle valve 90. There is a demand for the development of a new type of angle valve 90 that solves the problem.
