Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention according to the embodiment.

Figure 1a, Figure 1b is a front view and a side view showing the appearance of the subject innovation, this ball valve is a valve having a suction port 11 and the discharge port 12 so as to discharge the gas introduced to one side to the other side as usual It is formed of a body (1), the inside of the valve body (1) between the inlet 11 and outlet 12 is provided with a sphere (not shown) connected to the upper handle 13 and the shaft to operate together It is configured to perform the opening and closing operation by the operation of the sphere (회전) by the rotation operation of the handle (13).

In such a ball valve, the present invention has a filtering unit (2) as a means for removing various foreign matter in the gas introduced into the valve body (1) through the inlet 11 on the lower side of the valve body (1) It is provided, the filtering unit 2 is formed of a cap 21 in which an air filter (not shown) is built, and the cap 21 is helically coupled to be detachable to the valve body (1). In addition, an exhaust port (not shown) is formed in the filtering unit 2 to discharge residual gas, and the exhaust port 23 is opened and closed by a rotation operation of the knob 25A formed outside the cap 21. An opening / closing valve (not shown) for performing an operation is formed.

Figure 2a, Figure 2b is a cross-sectional view showing the internal structure of the present invention, as shown in the present invention has an inlet 11 and outlet 12 on one side and the other side connected between the upper handle 13 therebetween A valve body (1) having a sphere (14) is provided, and a lower portion of the valve body (1) is provided with a cap (21) in which an air filter (22) is embedded so as to filter out various foreign substances contained in the gas introduced into the inside. Is provided with a filtering unit (2) formed, the cap 21 is coupled to be detachable to the valve body (1) by the spiral coupling.

In addition, an outlet passage 16 and an inlet passage 15 are formed in the central portion of the valve body 1 and both sides thereof so as to communicate with the filtering unit 2, and between the outlet passage 16 and the inlet passage 15. The filter unit 2 of the provided with a cylindrical air filter 22 is opened downward, the air hole 22A is formed in the center of the upper side of the air filter 22, the porosity through which only gas can pass It is made of a metal sintered alloy having a.

In addition, an exhaust port 23 is formed at a central portion of the cap inside the air filter 22 so as to discharge gas remaining in the valve body 1 to the outside, and the opening and closing operation may be performed at the exhaust port 23. The on-off valve 25 is provided so that the on-off valve 25 is connected to the knob 25A formed on the outside of the cap 21 to the shaft to perform the opening and closing operation by the rotation operation of the knob 25A. It is configured to be. In addition, the on-off valve 25 has a vent hole 24A in the upper side center portion and is provided in the fixing tube 24 opened to the lower side, and the fixing tube 24 is inserted into and fixed to the exhaust port 23, and the fixing tube ( 24) The silencer 26 is provided to reduce the exhaust noise while discharging the gas.

At the same time, the opening 14 of the valve body 1 has an opening 14 communicating with the inflow passage 15 corresponding to the inlet 11 of the valve body 1 as shown in FIGS. 3A and 3B. Is formed, the inlet 142 is formed in communication with the delivery path 16 of the valve body 1 from the central portion to the lower side, the outlet 12 of the valve body 1 while forming a perpendicular to the inlet 142 in a vertical direction And a first outlet 143 is formed. In addition, the sphere 14 has a second outlet 144 communicating with the inlet 142 while forming a right angle with the first outlet 143 in the horizontal direction, and configured to coincide with the outlet 12 at every 90 ° rotation. do.

The following describes the operation and operation of the present invention configured as described above.

First, the opening and closing operation is performed by operating the handle 13 of the valve body 1, FIG. 3A is an open state, and FIG. 3B is a closed state. In the open state, since the opening and closing groove 141 of the mouth 14 communicating with the inlet passage 15 coincides with the inlet 11, the external gas passes through the inlet 11 and the opening and closing groove 141 and the inlet passage 15. The inlet gas is introduced into the filtering unit 2, and the introduced gas is filtered while passing through the air filter 22, and again, the outlet passage 16 of the valve body 1 and the inlet 142 and the mouth of the sphere 14 are formed. It is discharged through the outlet (143) and the outlet (12) of the valve body (1).

When the handle 13 is rotated 90 ° again in this state, the opening and closing groove 141 of the sphere 14 does not coincide with the inlet 11 of the valve body 1 as shown in FIG. 3B. When the inlet port 11 is closed by being closed, and the exhaust port 23 of the filtering unit 2 is opened by the rotation operation of the knob 25A, the internal residual gas is discharged to the outside while the external gas inlet is blocked. You will be able to.

As described above, the present invention is provided with a means for filtering various foreign substances contained in the inflow gas together with opening / closing operation of the valve to prevent damage and malfunction of the device due to the foreign substances, as well as separate filtering. Since the apparatus becomes unnecessary, the pipe structure can be simplified.

In addition, the present invention has a vent function while maintaining a closed state, and when repairing or replacing a specific part of a pipe, the residual gas can be discharged only in that part without the remaining gas discharge work of the entire pipe as in the past. There is an effect that can be made more quickly and efficiently simply.
