Self-operated thermostatical gas distributor

Abstract

The invention discloses a self-operated thermostatical gas distributor, and belongs to the technical field of cement mixing and stirring water temperature control. The gas distributor comprises a main control valve, a temperature control pilot valve and a gas distributing tube. At normal temperature, a temperature memory alloy is in a state of shrinking, a resetting spring forces a guide ring in a valve plug sleeve to move upwards, then the guide ring drives an upper coupling lever and a lower coupling lever to move upwards, so that a large sealing packing ring at the bottom of a large piston is forced to leave a gas outlet in a valve body; the pressure in a decompression cavity of a main valve is decompressed, then, the main control valve opens, the saturated steam heats the water in a pool through a main tube and gas distributing holes; when the water is heated to a certain temperature, the temperature memory alloy of the temperature control pilot valve expands to drive the upper coupling lever and the lower coupling lever to move downwards, then, the temperature control pilot valve closes to drive the main control valve to close.

Description

technical field [0001] A self-operated constant temperature steam distribution device belongs to the technical field of cement mixing water temperature control. technical background [0002] The quality of cement, a necessary material in construction, is not only related to the quality of the cement itself, but also related to the technical problems in the process of mixing cement with water, such as the amount of water added, the temperature of water added in different seasons, Is it fully stirred and so on. Among them, the control of water temperature is more critical, and there are many problems. The mixing process of cement is generally carried out in the cement mixing station. In order to produce large-scale production, the mixing station uses a larger pool to heat up the water. When the temperature reaches the required temperature, it is pumped into the mixer truck by the cement pump for mixing. Due to the large amount of water to be heated, the temperature rise also...

AI Technical Summary

Problems solved by technology

Due to the large amount of water to be heated, the temperature rise also needs to be fast, so manufacturers generally install boilers on site and pass saturated steam into the pool for heating; the water temperature is controlled by installing a temperature sensor in the pool , and then through the temperature control instrument to control the solenoid valve, the defect is that the solenoid valve is easily damaged when it works in saturated steam and frequent operation, so it must be replaced by a new technology that is more reliable and not easy to damage
