A monitor valve contains: a body, at least one monitoring assembly, a stop ball, an inlet connector, and a transmission device. The body is hollow and includes an inlet channel, an outlet channel, at least one orifice, a chamber, a neck opening, a plurality of trenches, and a first hole. The at least one monitoring assembly is mounted in the at least one orifice of the body. The stop ball is accommodated in the chamber of the body and includes a first close ring, a first aperture, and two second apertures. The inlet connector is locked in the inlet channel of the body and includes a guiding portion, a second close ring. The guiding portion has a central passage and plural passages, and each passage has an inlet. The transmission device is rotatably fixed in the first hole of the body to control the stop ball to rotate.

1. A monitor valve comprising: a body being hollow and including an inlet channel defined on a first end thereof, an outlet channel formed on a second end thereof, at least one orifice arranged on at least one side thereof adjacent to the outlet channel, a chamber defined between the at least one orifice and the inlet channel, a neck opening defined between the chamber and the at least one orifice, a plurality of trenches arranged around a peripheral side of the chamber, and a first hole formed on the body opposite to the chamber;at least one monitoring assembly mounted in the at least one orifice of the body;a stop ball accommodated in the chamber of the body and including a first close ring disposed between the stop ball and the neck opening, and a first aperture and two second apertures which are formed on three positions of the stop ball, wherein the first aperture is in communication with and is perpendicular to the two second apertures;an inlet connector locked in the inlet channel of the body and including a guiding portion formed on one end of the inlet connector and accommodated in the chamber of the body, the inlet connector also including a second close ring defined between the guiding portion and the stop ball, wherein the guiding portion has a central passage formed therein and has plural passages arranged around a peripheral side of the guiding portion, and wherein each passage has an inlet formed thereon;a transmission device rotatably fixed in the first hole of the body to control the stop ball to rotate. 2. The monitor valve as claimed in claim 1, wherein each monitoring assembly includes a first screw nut screwing with each of the at least one orifice and includes a window fixed in the first screw nut of the body. 3. The monitor valve as claimed in claim 2, wherein each monitoring assembly also includes a closing washer fixed between each of the two orifices and the first screw nut. 4. The monitor valve as claimed in claim 1, wherein two orifices are arranged on two sides of the body adjacent to the outlet channel. 5. The monitor valve as claimed in claim 4, wherein each monitoring assembly includes a first screw nut screwing with each of the at least one orifice and includes a window fixed in the first screw nut of the body. 6. The monitor valve as claimed in claim 5, wherein each monitoring assembly also includes a closing washer fixed between each of the two orifices and the first screw nut. 7. The monitor valve as claimed in claim 1, wherein two diameters of the two second apertures are different. 8. The monitor valve as claimed in claim 1, wherein the stop ball also includes a recess defined thereon to correspond to the first hole, and the transmission device includes a handle bar, a disc, and a control shaft, wherein the control shaft is rotatably fixed in the first hole of the body and has an extension and a bolt formed on one end of the extension and mounted in the recess of the stop ball, and the extension extends out of the body; the disc is disposed on the body and includes a through hole defined therein to insert through the extension; the handle bar is placed on the disc and has a coupling segment and a griping segment, wherein the coupling segment has a limiting orifice, and the extension of the control shaft inserts through limiting orifice of the handle bar and the through hole of the disc, and the extension is connected with the handle bar, such that the handle bar drives the control shaft to rotate. 9. The monitor valve as claimed in claim 8, wherein the transmission device further includes a positioning set, and the disc also has at least three fixing portions which are separated a radius distance from the through hole and are spaced from one another, and each fixing portion is a notch or a hole, the coupling segment of the handle bar has an affix orifice, wherein the positioning set is secured between the affix orifice of the handle bar and one of the at least three fixing portions, and the positioning set has a spring holder, a resilient element, and a rolling ball, wherein the spring holder is disposed in the affix orifice and accommodates the resilient element which abuts against the rolling ball, such that the rolling ball is partially accommodated in and is biased against the one of the at least three fixing portions. 10. The monitor valve as claimed in claim 8, wherein a second screw nut of the transmission device is screwed with the extension of the control shaft via the handle bar. 11. The monitor valve as claimed in claim 1, wherein the guiding portion has seven or five passages isometrically arranged around the peripheral side thereof. 12. The monitor valve as claimed in claim 11, wherein each passage is arcuate or rectangular. 13. The monitor valve as claimed in claim 1, wherein each passage is arcuate or rectangular.
