30 non-check-valves of valve for pressure difference core segment, may make threeway side into the pipeline medium on ball valve 5 under a certain pressure
Opening passes through, and the pipeline medium of threeway side recessed region valve 1 can not pass through, into upper only assembling position under valve for pressure difference core segment 30
Structure influences conduit running.The ready-made one over-pressed reflux cycle circuit before fan coil, solution pipeline pressure is excessive, and blocking etc. is asked
Topic, makes the prior art more perfect improvement project.Extend 31 inner wall of tube portion to be equipped with and the cooperation of valve for pressure difference core segment 30
Card slot 35.
The threeway side of Fig. 1 is in an open state into ball valve 5,50 phase of lower water inlet 51 and lower outlet 52 and upside port
It is logical.Fig. 3 is threeway side into 5 closed state of ball valve, and lower water inlet 51 and upside port 50 communicate, and lower outlet 52 is in valve ball 56
The lower partition of effect.
Threeway side recessed region valve 1 with extend tube portion 31 by O-ring and be threadedly coupled that realization is fixed and sealing, extension
Tube portion 31 has better controllability, and the size distance for extending tube portion 31 is adjusted according to the distance of different fan coils.
The interface of fan coil is usually internal thread, has fixed distance, different style spacing are different, to make this wind
Machine coil pipe temperature control valve group adapts to different spacing, the valve group with Telescopic is devised, using the soft seal of special construction
Structure is realized.The hermetic unit 32 includes the rubber ring 34 of bottom in a screwed cap 33 and a screwed cap 33, rubber ring
34 contact under squeezed state with the outer wall of the end face of upside port 50 53 and extension tube portion 31.This is simple in structure effectively,
Accessory is few, at low cost, has feasibility of efficiently constructing.
The axis in a state of use of lower outlet 52 of the upper water inlet 12 of threeway side recessed region valve 1 and threeway side into ball valve 5
Heart direction is parallel, this also has benefited from extending tube portion 31 and threeway side into 5 separate structure of ball valve and above-mentioned soft sealing structure,
So that the connection positioning of the more suitable fan coil pipe structure of the invention.
In the present embodiment, upper water-out mouth 11 and lower water inlet 51 use external thread structure, and internal thread, ring flange can also be used
Etc. connection structures；In addition upper water inlet 12 and lower outlet 52 use slip-knot internal thread structure, and external screw thread, interior spiral shell can also be used
Other connection structures such as line.
