AI Technical Summary

Technical Problem

The existing condensate recirculation regulating valves are prone to damage to the valve core in high-pressure environments, and have high leakage requirements when closed, which affects system safety and maintenance costs.

Method used

A new type of condensate recirculation regulating valve was designed. By setting up water inlet pipes, S-type pipes and connecting pipes and partitions, the water flow pressure was reduced. The S-type pipe was used to make the water flow undergo multiple bending and direction changes, increasing friction resistance, reducing water flow pressure, and reducing damage to the valve core.

Benefits of technology

It effectively reduces pressure damage to the valve core by water flow, improves the service life of the valve core, and reduces maintenance costs.

Abstract

The novel condensed water recirculation regulating valve comprises a valve body, a valve cover and a sealing cover are arranged on the valve body, flange plates are fixedly arranged on the two sides of the valve body, a valve cavity is formed in the valve body, a water outlet pipeline is arranged on one side of the valve cavity, a valve element is movably arranged in the valve cavity, and a water inlet pipeline is arranged on the other side of the valve cavity. Through the arrangement of a water inlet pipeline, an S-shaped pipeline, a connecting pipeline and a partition plate, water flow enters the S-shaped pipeline from the water inlet pipeline, the S-shaped pipeline enables the water flow to be subjected to multiple times of bending and direction change, so that the flow speed is reduced, bending and steering of the S-shaped pipeline enable the water flow to generate extra resistance, and therefore pressure loss is caused; after water flow enters the connecting pipeline through the S-shaped pipeline, friction resistance to the water flow is increased by the partition plate, pressure of the water flow is reduced, the pressure is reduced, damage of the pressure to the valve element is reduced, the service life of the valve element is prolonged, and maintenance cost is reduced.
