Tubular internal magnetic force opening valve

Abstract

The invention provides a tubular internal magnetic force opening valve. The tubular internal magnetic force opening valve comprises a valve casing, a valve body and a valve element. A through water through hole is machined in the middle of the valve body. A conical sealing hole is machined in the front end of the water through hole. A screw rod is connected with the interior of the valve body. The valve element is rotationally assembled at the front end of the screw rod. An inner annular transmission ring is fixedly connected to the valve element through a circumferential ribbed plate. Inner magnets are circumferentially and evenly distributed on the inner transmission ring. An outer annular transmission ring is designed on the exterior of the valve casing. Outer magnets are evenly distributed inside the outer transmission ring. The magnetic poles of the inner magnets are opposite to the opposite magnetic poles of the outer magnets. The valve casing totally wraps the inner elements of the valve with no dead angles or weak spots. The valve element is directly turned on or turned off through magnetic force in a crossing-air mode, so that abrasion is small. The tubular internal magnetic force opening valve is not prone to corrosion or aging, longer in service and not likely to be damaged during operation.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a tubular internal magnetic force opening valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. The opening and closing of the traditional valve is realized by the valve stem. The traditional valve stem needs to pass through the valve body and connect with the valve core to control the movement of the valve core. In this way, the valve is used for a long time, and it is easy to open and close after many times. Aging and wear, resulting in water leakage at the contact part of the valve stem and the valve body. In addition, since the valve stem needs to be able to move, the contact between the valve stem and the valve body needs to be a sliding sealing structure, so that when the v...

Problems solved by technology

In addition, the traditional valve stem structure needs to be designed outside. Long-term placement makes the valve stem very easy to age. If a metal valve stem is used, the valve stem is very easy to rust after long-term use.

In addition, the traditional valve stem needs to occupy a large space, which is often not conducive to the placement of the valve.

During the use of the two external valves, the valve is easy to be controlled by people due to the external valve, but this will also cause inconvenience to people in some cases. For example, when the water supply bureau cuts off the water for some people, it is too easy to open The valve makes it possible for the user whose water is cut off to open the water valve by himself, so that the water cutoff fails
