Abstract

This invention relates to pipe fittings. The purpose of the invention is to increase the reliability of the valve by allowing the centering of the flow of the working medium. When a voltage is applied to the electromagnet 7, which creates a rotating magnetic field, the rotor 3 rotates and, with its teeth 5, rotates the petals 6 through the teeth 4, which block or open the valve flow area. 4 il.

Description

This invention relates to pipe fittings.

The purpose of the invention is to increase the reliability of work due to the possibility of centering the flow of the working environment,

FIG. 1 shows a general view of the valve; figure 2 - section aa in figure 1; on fig.Z - one petal; figure 4 - view B in fig.Z.

The valve contains a cylindrical body 1 of a magnetically permeable material, a pipe 2, a rotor 3 of a ferromagnetic material with teeth 4 and located along its inner perimeter, kinematically connected with it by a gear connection with teeth 5 rotary lobes 6 of durable alloy steel. An electromagnet 7 is located outside the body 1. Each lobe 6 has its own rotation axis 8, fixed to the base of the cylindrical body, and provided with grooves 9 so that the end portion of the mating petals can enter into them. Slots 9 are made

the function of guides for their associated petals. 6.

The shape of the grooves allows the petals 6 to move in the same plane, closing or opening the inlet of the pipeline 2.

The valve operates as follows.

The electromagnet 7 creates a rotating magnetic field, driving the rotor 3 and the rotating loops 6 coupled to it. Each petal, rotating around axis 8, moves along groove 9, conjugate to it 6, reducing the cross-sectional area of the duct of the pipeline 2 from full open to full close Moreover, the shape of the channel bore is close to the circle due to the use of a multi-lobe structure of the closure member.

When the valve is closed, the flow of the working medium is blocked due to the tight fit of the guide grooves 9 in the rotary gearboxes.

pistachki 6. For example, when closing, the first petal with an end edge enters the upper groove of the second, the second petal enters the upper groove of the third with its front edge, etc., the last petal enters the upper groove of the first petal with its front edge.

The opening of the passage channel of the pipeline 2 is carried out when a voltage is applied to the electromagnet 7, which creates the effect of rotating the magnetic field in the opposite direction, which leads to a corresponding change in the direction of movement of the rotor 3. At the same time, the rotary lobes 6, returning to the initial state, increase the area channel cross-section up to full open. In the open state, the rotary petals 6

release the passageway of the pipeline 2.
