The valve is a commonly used device in pipeline connection and liquid flow control. In the existing valves, the rotary switch handle is usually set on the top or side of the valve body, but in some occasions where the switch is not frequent and the pipeline installation gap is small Therefore, it is necessary to leave a large space for the installation of traditional valve parts to facilitate manual screwing of the handle, which will inevitably cause a certain waste of space, and the overall structure of the traditional valve is more complicated, and the manufacturing cost is higher.

Contents of the invention

The technical problem to be solved by the utility model is to provide a valve that takes up little space and can be switched by rotation. Its main purpose is to provide a valve that can control the flow of water by rotating the casing by hand. Simple, low cost, especially suitable for occasions with infrequent switching and small installation gaps.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:

A rotary switch valve, including a water inlet valve tube, a movable domed top, a movable valve core, a water outlet valve tube, a rotating sleeve, sleeve connecting bolts, and a sealing ring. The external rotating sleeve is composed of upper and lower parts connected by bolts And the two ends are respectively fixed in the sealing ring grooves of the water inlet valve pipe and the water outlet valve pipe. The side of the inner movable valve core with the centering circular boss is in contact with the end face of the inner pipe head of the water outlet valve pipe with the centering circle groove. The tapered hole on the other side of the moving spool is in contact with the movable dome at the inner end of the water inlet valve tube, and the symmetrical projections on the edge of the moving spool are embedded in the fixed groove on the inner wall of the rotating sleeve and rotate together with the rotating sleeve.

The water inlet valve pipe has a sealing ring groove, and one end of the sealing ring is embedded in it, and the end of the rotary sleeve without opening and closing indicating the engraved line is in contact with the sealing ring; the inner pipe head of the water inlet valve pipe is equipped with a spring The movable domed top is in contact with the tapered hole on the movable valve core, and the outer end is connected with the water inlet pipe by threads.

There is a sealing ring groove on the water outlet valve tube, and the other end of the sealing ring is embedded in it, and the rotary sleeve has an opening and closing indicating marked line end in contact with it; the inner edge of the water outlet valve tube has a movable valve core rotation limit There are two bumps, one edge bump of the movable valve core rotates between the two limit bumps, the hexagonal boss is marked with opening and closing indicating marks, and the outer pipe head is connected with the water outlet pipe by threads.

The movable spool has a centering circular boss on the side that contacts the inner end of the water outlet valve pipe, and a tapered hole in the center of the other side that contacts the movable domed top of the water inlet valve pipe. Symmetrical bumps for tube contact.

The rotating sleeve is composed of upper and lower parts, which are connected and fixed by four bolts. There is a sealing ring groove on the contact surface of the two parts and the contact surface with the water inlet valve pipe and the water outlet valve pipe. The connection end of the water outlet valve tube is marked with an opening and closing indicator point to control the size of the water flow. There is a slot on the inner wall of the upper and lower sleeves, and the symmetrical protrusions on the edge of the moving valve core are embedded in it. When the sleeve is turned by hand, it will move The spool turns.

The beneficial effect of the utility model is that the whole valve is simpler than the traditional structure through the direct contact between the rotating sleeve and the water inlet and outlet valve tubes, and when the rotating sleeve moves with the moving valve core, it is very convenient to control the size of the water flow. This integrated rotary switch valve has a compact structure and low production cost, and is especially suitable for occasions where switching is infrequent or the installation space of the valve is insufficient.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Figures 1 to 5, the rotary switch valve mainly includes a water inlet valve tube 10, a movable dome 12, a rotating sleeve 20, a sleeve connecting bolt 24, an outlet valve tube 30, a moving valve core 50, and a sealing ring. 40, the upper and lower parts of the external rotating sleeve 20 of the valve are fixed together by four connecting bolts 24, and there are sealing ring installation grooves 22 on the two contact surfaces, and the sealing ring 40 is installed in it and fixed on the rotating sleeve 20. The two ends of the sealing ring 40 in the valve are respectively in contact with the sealing ring groove 11 of the water inlet valve pipe and the sealing ring groove 31 of the water outlet valve pipe for sealing and waterproofing; A centering circular groove 35 is left, and a centering circular boss 53 is correspondingly left on the movable valve core, which is convenient for centering installation; there is a tapered hole 51 in the center of the other side of the moving valve core 50, and a symmetrical protrusion 52 is embedded in it. On the lug groove 21 on the inner edge of the rotary sleeve, when the rotary sleeve 20 is rotated, the movable valve core 50 is rotated; the inner end of the water inlet valve pipe 10 has a movable domed point 12 in contact with the tapered hole 51, and pushes against it. The contacting movable valve core 50 is tightly attached to the inner end surface of the water outlet valve pipe 30 to prevent water leakage.

There are two movable spool 50 on the inner end edge of the water outlet valve tube 30 to limit the rotation of the protrusions 32, and an edge-symmetrical protrusion 52 of the movable spool 50 moves between the two rotation limited protrusions 32; What is more important is the full-open indication score line 33 and the full-close indication score line 34 on the hexagonal boss; when the rotating sleeve 20 is rotated by hand, the rotating sleeve 20 will rotate with the moving valve core 50 to realize the control of water flow. When the opening and closing indicating point 21 is aligned with the fully open indicating reticle 33, it is in the maximum flow state. When the sleeve 20 is reversed, when the opening and closing indicating point 21 is aligned with the fully closed indicating reticle 34, it is in the closed state.
