BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a piping installation for controlling fluid, and more particularly to a water control valve.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98

The known pull-type water control valve comprises a valve casing, a valve handle, a driving seat, a movable valve plate, a fixed valve plate and a valve seat. Wherein the driving seat, the movable valve plate and the fixed valve plate are assembled in the valve casing. The movable valve plate and the fixed valve plate are made of ceramics. The movable valve plate and the fixed valve plate overlap each other. The driving seat is in contact with the movable valve plate. The valve seat is assembled on one end of the valve casing. The fixed valve plate is in contact with the valve seat. One end of the valve handle is in contact with the driving seat. The other end of the valve handle protrudes out of the valve casing.

The valve handle is pulled laterally, the valve handle pulls the driving seat to slide laterally, so that the movable valve plate slides laterally, changing the flow of water through the water control valve or controlling the water to or not to flow through the water control valve.

The conventional press-type water control valve pulls a valve handle to move back and forth with a press structure, so as to change the internal flow path on/off of the water control valve to control the water to or not to flow through the water control valve.

BRIEF SUMMARY OF THE INVENTION

The fundamental purpose of the present invention is to provide a water control valve, which can enhance the handiness and can control the flow or on/off.

In the present invention is a water control valve which comprises a valve casing, a valve seat, a fixed valve plate, a movable valve plate, a driving piece, a press structure and a pulling structure, wherein the valve seat is assembled on one end of the valve casing. The fixed valve plate, the movable valve plate and the driving piece are disposed in the valve casing. The fixed valve plate is in watertight contact with the valve seat. The movable valve plate and the fixed valve plate overlap each other. A flow channel for the fluid is formed among the valve seat, the fixed valve plate and the movable valve plate. The driving piece is in contact with the movable valve plate, so that the driving piece drives the movable valve plate to slide laterally to regulate the flow of the fluid through the flow channel or the on/off of the flow channel A joint holder is disposed in the valve casing, and the joint holder is provided with a through groove, one end of the through groove is oriented to the driving piece. One end of the joint holder is adjacent to the driving piece; the other end of the joint holder is provided with a shelly supporter. One end of the supporter far from the joint holder is provided with a support plate.

The press structure comprises a positioning element, a press cap and a follower, wherein the positioning element is in contact with the support plate, so as to position the press structure. The positioning element is provided with a positioning structure. The press cap is pivoted on the positioning element. The follower is axially opposite to the press cap, so that the press cap presses the follower to move axially, the follower is located in a first position or a second position by the positioning structure. the pulling structure comprises a first shaft lever, a connecting rod, a swing piece, a pivot and a spring, wherein the first shaft lever penetrates the support plate, and one end of the first shaft lever is in contact with the follower, the other end of the first shaft lever is located in the supporter, the first shaft lever is axially put in the spring, both ends of the spring prop the support plate and the follower respectively; the connecting rod is laterally opposite to the first shaft lever; a first hinge arm laterally protrudes from the first shaft lever, the first hinge arm is laterally pivoted on the connecting rod. The swing piece is provided with a second shaft lever and a drawing part. One end of the second shaft lever is laterally opposite to the connecting rod. A second hinge arm laterally protrudes from the second shaft lever. The second hinge arm is laterally pivoted on the connecting rod, and the first hinge arm is located between the second hinge arm and the support plate. The pivot laterally penetrates the swing piece, and the first hinge arm, the second hinge arm and the pivot are parallel. The swing piece is held in the through groove; both ends of the pivot are pivoted on the joint holder respectively.

The axis of the first shaft lever is orthogonally projected on the connecting rod to form a virtual first line, a virtual second line is connected to the axes of the first hinge arm and the second hinge arm. The second line is orthogonal to the first hinge arm and the second hinge arm respectively. The first line obliquely contacts the second line. The driving piece forms an insert hole. The drawing part is pivoted in the insert hole, hereby, the follower pulls the first shaft lever to move back and forth. The swing piece rotates round the pivot; the drawing part draws the driving piece to drive the movable valve plate to slide laterally, so as to enhance the handiness of flow control or on/off of the flow channel.

In the present invention, the press cap is pressed, so that the movable valve plate slides laterally against the fixed valve plate to regulate the flow of the fluid through the flow channel or the on/off of the flow channel.
