Thermostatic valve with preset flow distribution ratio

Abstract

The invention relates to a thermostatic valve with the preset flow distribution ratio, and belongs to the technical field of thermostatic valve structural optimization. The thermostatic valve comprises a valve body provided with a mandrel, a bonnet and a thermostatic valve controller. The outer wall of the mandrel is provided with a first limit clamping groove, a second limit clamping groove and a third limit clamping groove sequentially from top to bottom. The first limit clamping groove, the second limit clamping groove and the third limit clamping groove are provided with open rings inside in matched and clamped manners. The first limit clamping groove is located in the bonnet, the outer wall of the mandrel between the second limit clamping groove and the third limit clamping groove is provided with a large copper gasket, a seal gasket, a first small copper gasket, a first small O-shaped seal ring, a sliding sleeve sequentially from up to down. The outer wall of the mandrel inside the bonnet is provided with a spring, a second small copper gasket and a second O-shaped seal ring. The first limit clamping groove is located above the spring. The thermostatic valve has the advantages of simple structure, flexibility and convenience of production, low manufacturing cost, high production efficiency, high yield, accuracy of arrangement, long service life and the like.

Description

technical field [0001] The invention relates to a thermostatic valve with a preset flow distribution ratio, and belongs to the technical field of structural improvement of thermostatic valves. Background technique [0002] Three-way thermostatic valves are mainly used in single-pipe heating systems with spanning pipes. The initial ratio of the bypass and straight-through of the current thermostatic three-way valves is fixed, and the bypass shunt coefficient can be achieved by manually adjusting the handwheel. Change within the range of 0 to 100%. [0003] In the actual operation of the current single-pipe heating system with spanning pipes, there are inconsistent flow rates in rooms with different distances from hot water pipes or different floor heights, resulting in large differences in heating effects and poor heating comfort; Frequent manual adjustments by users cannot be consistent and unified, and it is in a disordered state, and the flow of hot water between users is...
