Problems solved by technology

However, in the existing balance valve, the spool is usually vertically connected between its liquid inlet and its outlet, so that the balance valve is T-shaped or Y-shaped, resulting in a large space occupied by the balance valve, which is not easy to install in a small space. , and even need to adjust the layout of the pipe network to match the balance valve, and the existing valve core structure is complicated, and the assembly and follow-up maintenance operations are complicated

Abstract

The invention relates to the technical field of valves, and discloses a linear type balance valve. The linear type balance valve comprises a valve body, a bonnet, a sliding ring and a membrane, wherein the valve body is matched with the bonnet, and a matching cavity located in the middle and a control cavity located on the periphery are formed; an inlet connector and a pressure guide connector connected with a water inlet of a proportional mixer are arranged on the valve body; an outlet connector is arranged on the bonnet; the periphery of the sliding ring is in sliding fit with the matching cavity; the sliding ring is provided with a liquid passing channel communicating with the inlet connector and the outlet connector respectively; the sliding ring, the inlet connector and the outlet connector are located on the same axis; the inlet connector is provided with a valve plate; a valve port capable of being close to the valve plate is formed in the end, facing the inlet connector, of thesliding ring; the membrane is connected between the valve body and the sliding ring and divides the control cavity into a front cavity and a rear cavity; the rear cavity communicates with a water outlet connector; and the front cavity communicates with the pressure guide connector. The linear type balance valve has the advantages that the pressure difference between water and foam stock solutionis accurately controlled, so that the purpose of accurately controlling the mixing ratio is achieved, the overall structure is simple and compact, and the occupied space is small.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a linear balance valve. Background technique [0002] The foam fire extinguishing system maintains the pressure balance when the foam stock solution and water enter the proportional mixer, and dynamically adjusts the amount of foam stock solution entering the proportional mixer through the balance valve, so that the foam stock solution and water can be mixed in a specified ratio, so that the generated foam can be mixed Liquid works best. However, in the existing balance valve, the spool is usually vertically connected between its liquid inlet and its outlet, so that the balance valve is T-shaped or Y-shaped, resulting in a large space occupied by the balance valve, which is not easy to install in a small space. , and even need to adjust the layout of the pipe network to match the balance valve, and the existing valve core structure is complicated, and the assembly and follow-up m...
