Abstract: A water valve includes a valve body, a stationary sleeve, and a movable sleeve. The stationary sleeve is received in the valve body, and the movable sleeve is slidably disposed in the stationary sleeve. A partition plate is formed in the movable sleeve to partition the movable sleeve into a cold water cavity and a hot water cavity at two ends respectively. An external wall of the movable sleeve is formed with an annular groove positionally corresponding to the partition plate. When the partition plate is pushed under different pressure of cold water and hot water, the movable sleeve is moved to regulate flow ratio of cold water and hot water. Besides, water is received in the annular groove and the gap between the stationary sleeve and the movable sleeve for cushion and lubrication. Thus, the movable sleeve is easier to move for regulation.

Abstract: A check valve is provided. The check valve includes a position limiting member, a back-flow preventing member and a lid body. The back-flow preventing member is disposed between the position limiting member and the lid body, and a blocking portion of the back-flow preventing member is flexible. When the blocking portion is impacted by an external water source, a gap will be formed between an external peripheral verge of the blocking portion and a stepped portion of the position limiting member to allow the water source to flow through the position limiting member. When the blocking portion is impacted by a reverse water source, the external peripheral verge of the blocking portion is abutted against the stepped portion to unallow the water source to flow through the position limiting member.

Abstract: A temperature-controlling water valve includes a main body, a main valve, and a screw element to screw with a threaded portion on the main body. The main body defines a height direction and a horizontal direction perpendicular to each other. The main body has a first end and an opposite second end along the height direction. A cold and a hot water inlets opposite to the first end are formed at the second end. Cold water and hot water are mixed in the main body and flow out from an outlet between the first and the second ends along the horizontal direction. The main valve disposed in the main body is able to regulate water amount flowing in, and one end of the main valve is exposed above the second end. Thereby, the present invention is able to be installed easily.

Abstract: A faucet has a multiway tube and a water mixer installed in the multiway tube. The water mixer has a balance unit and a mixing element, and the water mixer can be connected to two water sources. When the pressure of one water source varies rapidly, the balance element can modulate the effect that may influence the flow rate of each water source. The mixing element is, on the other hand, adapted to mix the two water flows. As such, the faucet of the present invention can stabilize the temperature of the mixed water outlet.

Abstract: A protective cover of the present invention is adapted to be disposed on a wall-mounted faucet. The protective cover includes a cover plate. Two protruding posts, two abutting posts, and two extension posts vertically extend from one surface of the cover plate. Each distal end of the protruding posts is formed with a location hole. Each distal end of the extension posts is formed with a hook portion. Therefore, the protruding posts and the abutting posts can abut against the wall-mounted faucet so as to make the location hole receive the location shafts of the faucet and make the hook portions abut against the faucet. Thereby, the present invention can be firmly disposed on wall-mounted faucets to provide a protective effect.

Abstract: A water valve assembly of the present invention includes a temperature controller, a main controller, and a connecting tube disposed therebetween. Water entering the temperature controller further enters the main controller via the connecting tube and is discharged from the main controller. The temperature controller and the main controller are arranged in an edge of bathtub, and the connecting tube is parallel to the edge of bathtub. Also, water always flows not parallely to a width of the edge of bathtub in the water valve assembly. Thus, the water valve assembly of the present invention is able to be installed in a narrower edge of bathtub.

Abstract: A non-return structure of water valve includes a valve body, two limiting elements, and two non-return elements. The valve body forms two inlets and two annular protrusions around the two inlets respectively. Each annular protrusion encloses a receiving room receiving one of the limiting elements. The limiting element defines a widened hole and a reduced hole, and a stepped portion is formed therebetween. The non-return element includes a blocking portion disposed in the widened hole and having an external diameter larger than the one of the reduced hole, and the blocking portion is resilient. Thereby, returning water is unable to separate the circumference of the blocking portion from the stepped portion to form gaps. Thus, the non-return structure of water valve is able to prevent water from flowing back.

Abstract: A quick connector includes a female adapter and two retainers. The female adapter has a joint portion and an axial hole being adapted for a male adapter inserting therein. The joint portion has two openings and two pairs of engaging portions. Each retainer includes a pair of pivot members positioned in one of two pairs of engaging portions, so that the retainers can pivot between a clamping position and a spreading position.

The retainers are positioned in the engaging portions so as to be installed and dismantled easily. One of the retainers pivots in a clockwise direction, the other one of the retainers pivots in a counterclockwise direction. Users can easily operate the retainers to pivot, and the retainers would not be obstructed by the wall.

Au such, flow rate is stabilized. Structure of the flow rate stabilizer is simplified, so that producibility and durability of the present invention is well performed.

Abstract: A faucet valve of the present invention includes a pressure valve and a mix valve. The faucet valve can be connected to two external water pipes. The pressure valve can balance the water amount from the water pipes when the water pressure of the water pipes changes. The mix valve can mix the water from the water pipes and then output the water. Thereby, the present invention can stabilize the water temperature by balancing the amount of the hot water and the cold water.

Abstract: A protective cover of the present invention is adapted to be disposed on a wall-mounted faucet. The protective cover includes a cover plate. Two protruding posts, two abutting posts, and two extension posts vertically extend from one surface of the cover plate. Each distal end of the protruding posts is formed with a location hole. Each distal end of the extension posts is formed with a hook portion. Therefore, the protruding posts and the abutting posts can abut against the wall-mounted faucet so as to make the location hole receive the location shafts of the faucet and make the hook portions abut against the faucet. Thereby, the present invention can be firmly disposed on wall-mounted faucets to provide a protective effect.

Abstract: A control valve assembly for a faucet of the present invention includes a main body, a mixing valve and a controller. The main body has a first inlet passage, a second inlet passage, a mixing room and a lateral outlet. The first inlet passage and the second inlet passage communicate with the mixing room. The lateral outlet is located on a side surface of the main body. The lateral outlet communicates with the mixing room. The mixing valve is used for adjusting a ratio between the fluxes of the first inlet passage and the second inlet passage. The controller is operated for controlling the mixing valve. Therefore, the inlets and the outlet are not gathered on the bottom of the main body. The structure of the faucet is simplified.
