Embodiment 2
[0059] see Figure 10 with Figure 11 In this embodiment, the working fluid inlet 401 is opened on the upper end cover 3, and the working fluid inlet 401 and the regulating section casing 17 are coaxial. Other unrelated parts are the same as in Example 1.
[0060] The working method of above-mentioned two embodiments is:
[0061] The driving screw 21 drives the outer guide ring 8 to rotate in the circumferential direction through the tooth portion 801, and the outer guide ring 8 gives force to the outer beam plate 13 through the connecting rod, and the adjacent trapezoidal outer plate 1301 connects the ring under the action of the force. 11 is an axis, the lower end of which is opened or closed. Correspondingly, the lower end of the trapezoidal outer plate 1301 drives the lower end of the trapezoidal inner plate 1401 to move outward or inward, so that the lower end of the entire inner beam flow plate 14 is opened or closed. closure;
[0062] When the lower end of the inner...

The invention discloses a working medium collecting device and method for adjusting the local flow velocity of a pipeline. The device adopts an inner-layer beam plate and an outer-layer beam plate to adjust a through-flow area of the pipeline, an inner-layer through-flow space and an outer-layer through-flow space are established with the assistance of a double-flow-channel sleeve, and the inner-layer through-flow space and the outer-layer through-flow space are mutually independent. According to the device, the outer-layer beam plate is driven by an outer-layer guide ring, the inner-layer beam plate is driven by the outer-layer beam plate to open, so that the local flow velocity in a system can be adjusted by driving a screw rod, the flow velocity of a working medium is adjusted locally for the system having requirements for the flow velocity of the working medium, the working medium runs within a reasonable flow velocity range, and normal operation of the system is prevented from being influenced by too low flow velocity.
Description
technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a working medium converging device and method for adjusting local flow velocity of a pipeline. Background technique [0002] According to the current stage of development, adhere to the principle of "determining power by heat", moderately build large-scale thermal power units in eligible large and medium-sized cities, and encourage the construction of back-pressure thermal power units; Pressure-type thermoelectric units; encourage the development of combined heat, electricity, and cooling. [0003] In recent years, the installed capacity of wind power and photovoltaic new energy has continued to increase, and at the same time, the overall power receiving scale has also increased significantly, and the contradiction of power grid peak regulation has become increasingly prominent. In order to alleviate the contradictions of the gap in the adjustment gap and improve the ...
