Abstract: A throttling explosion-proof pipe assembly includes a main body, a control member, a cover and an explosion-proof pipe. The explosion-proof pipe is provided with a coupling which has an interior provided with a mounting hole which has an inner diameter equal to an outer diameter of the main body. A nut is rotatably mounted on the explosion-proof pipe through 360 degrees. The nut is provided with an internal thread. The main body, the control member and the cover are integrated to construct a throttling valve that is received in the mounting hole of the explosion-proof pipe.

Abstract: A two-way flow control valve includes a valve body, a control member, a cover mounted and a gasket. The valve body has a first water hole, a plurality of first ribs and a plurality of first flanges. The cover has a second water hole, a plurality of second ribs and a plurality of second flanges. The control member has a passage. The control member is provided with two V-shaped inclined planes which are clamped respectively by the first flanges of the valve body and the second flanges of the cover. When the water passing through the two-way flow control valve is large enough to reach a determined value, the control member is stretched and deformed to reduce the diameter of the passage, and to partially block the first water hole of the valve body or the second water hole of the cover.

Abstract: A flow control valve includes a valve body, a control member and a cover. The valve body has a receiving space, a resting face, a stepped face, a positioning groove and a plurality of water outlet holes. The control member is provided with an elastic portion, a sealing portion and an abutting face. When a flow pressure of the fluid is under a normal condition, the elastic portion of the control member is contracted inward, so that the abutting face of the control member is disposed at an open state. When the flow pressure of the fluid is under an abnormal condition, the elastic portion is expanded outward and abuts the stepped face of the valve body, so that the abutting face of the control member abuts the resting face of the valve body, to seal the water outlet holes of the valve body.
