AI Technical Summary

Benefits of technology

This technology allows for precise regulation of tiny amounts (small flows) without wasting too many or expensive materials during certain times. It also improves upon traditional methods by reducing the size of an open square gate while still allowing it to accurately respond to changes in fluid pressure levels caused by temperature fluctuations.

Problems solved by technology

This patented describes an issue where there may be difficulties controlling the amount of water supplied from different sources depending upon their specific requirements or changing environmental conditions such as temperature. Current methods involve manually adjustable valves that can only provide precise amounts based on factors like pressure and flow rates. However, these techniques have limitations because they cannot adapt well to varying levels of demand without causing damage to equipment components overall.

Embodiment Construction

[0018] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the scope of protection of the present invention is not limited to the following Described embodiment.

[0019] Such as Figure 1-7 As shown, the flat gate with high-precision flow control of the present invention includes a rectangular gate 1 driven to open / close by a hoist, a gate opening that is rolling and sealingly matched with the rectangular gate 1, and a pre-embedded gate opening. pieces.

[0020] Such as image 3 As shown, the shape of the gate opening is composed of an upper rectangular hole 2.1 and a lower V-shaped hole 2.2; a V-shaped bottom sill is pre-embedded in the reinforced concrete orifice 2.3 of the V-shaped hole 2.2.

Abstract

The invention discloses a bulkhead gate with high-precision flow control. The bulkhead gate comprises a rectangular gate plate driven by a hoist to be opened/closed, a gate orifice in rolling or sliding sealing fit with the rectangular gate plate, and a gate orifice embedded part, wherein the shape of the gate orifice is composed of a rectangular hole in the upper portion and a special-shaped hole in the lower portion; and the width of the special-shaped hole is gradually reduced from top to bottom. The bulkhead gate has the advantages that when the opening degree of the gate is small, the overflowing area is much smaller than that of a common rectangular gate orifice, so that the accurate adjustment of small flow is realized. In the constant-speed lifting process of the rectangular gate, the overflowing area and the lockage flow are both increased in a non-linear mode, and the flow control precision under the condition that the gate is locally opened, especially under the small-opening-degree condition is improved, so that water resources are saved, and waste is avoided. Meanwhile, the phenomenon of gate vibration caused by small-opening overflowing of the conventional rectangular gate orifice is avoided.
