Embodiment Construction

[0028] Such as Figure 1 to Figure 14 As shown, the working principle of the first lifting and rotating structure of the improved drain valve is that when the ribs 5-4 on the valve core 5 correspond to the opening grooves 4-1 of the valve stem 4, the ribs of the valve core will be in the opening It moves up and down in the vertical stroke opened by the groove. Such as image 3 As shown, the upper end of the valve cap 6 is a diameter, the lower end is provided with an external thread, and the middle is a cavity. The external thread is connected with the internal thread of the water stop cap 3. When the external thread of the end of the valve stem 4 is tightened with the internal thread of the body 1, the valve cap 6 is lifted, and the valve core 4 rises to the opening groove 4 of the valve stem 4 along with the ribs 5-4 connected with the valve core. -1 end face, and then rotate the valve cap 6 by 10°~170°, the water stop cover 3 is separated from the water stop piece 2, the drain v...

Abstract

A kind of improved launch valve which refers to the field of valve is designed for the structure weakness of the valve-bar and valve-core. The main idea of the design is that the launch valve has two structures, namely the lift-draw spin structure and the up-down fluctuate structure. The launch valve comprises noumenon, valve-bar, valve-core, valve-cap; The first method is that at one end of the valve-bar set a hatch slot, set transverse slot, portrait circle hole, the base platform and reinforcing steel bar; The open-trough on one end of the valve-bar connects to the reinforcing steel bar of the valve-core through the glide and fit to each other. The portrait ring-hole on the valve-core connects to one part of the valve-bar by the uprightness lift-and-draw slide. Valve-cap spin an angle from 10 degree to 170 degree or spin to the angle between 171 degree to 11degree, the launch valve open or shut. The second method is that the lift-and-draw structure is make the located spring steel wire stretch and compose, realize to the open or shut of the launch valve, make the problem about the directional drain and the orientation with reason of the valve-bar and valve-core come true. The launch valve designed rationally, the operation capability is well.

Description

Technical field [0001] The invention relates to the field of valves, and is an improved drain valve. Background technique [0002] The present invention is a drain valve installed on the drain port of the bathtub and the toilet hopper. The body of the valve is connected with the connection piece of the bathtub and the bathroom hopper drain, and the valve cover controls the discharge or closing of the water. Previously, a similar type of drain valve was published in the patent literature, and it mainly used the sealing surface of the static sealing surface to realize the opening and closing of the drain valve. The advantage of this kind of drain valve is that the water in the basin can be discharged or closed easily, and the design of the valve stem and valve core structure has not yet been involved. Summary of the invention [0003] The present invention provides an improved drain valve and an opening and closing method to solve the structural optimization problem of the existin...
