30, and connect the upside port 50 that ball valve 5 is entered in threeway side；Water inlet 51 and center lumen under the left end of ball valve 5 are entered in described threeway side
Body 3 connects all the time；The upper water-out mouth 11 of the left end of threeway side recessed region valve 1 connects all the time with central cavity 3, and passes through region valve element
13 realize keying with upper water inlet 12；The outer wall of described central cavity 3 is to extend tube portion 31, extends tube portion 31 and three
The split of ball valve 5 is entered in logical side, and realizes by hermetic unit 32 to extend tube portion 31 and enter the sealing of ball valve 5 with threeway side and fix.
30 non-check-valves of valve for pressure difference core segment, may be such that the pipeline medium entered on ball valve 5 threeway side under a certain pressure
Opening passes through, and the pipeline medium of threeway side recessed region valve 1 can not be by entering upper only assembling position under valve for pressure difference core segment 30
Structure influences conduit running.A ready-made over-pressed reflux cycle loop before fan coil, solution pipeline pressure is excessive, and blocking etc. is asked
Topic, more perfect improvement project is made to prior art.Extension tube portion 31 inwall is provided with to be coordinated with valve for pressure difference core segment 30
Neck 35.
It is open mode that ball valve 5 is entered in Fig. 1 threeway side, lower water inlet 51 and lower outlet 52 and the phase of upside port 50
It is logical.Fig. 3 is that the closed mode of ball valve 5 is entered in threeway side, and lower water inlet 51 and upside port 50 communicate, and lower outlet 52 is in valve ball 56
Effect is lower to be separated.
Threeway side recessed region valve 1 is with extending tube portion 31 by O-ring and be threadedly coupled that realization is fixed and sealing, extension
Tube portion 31 has more preferable 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 cause 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.Described hermetic unit 32 includes a screwed cap 33, and the rubber ring 34 of the inner bottom part of a screwed cap 33, rubber ring
34 with the end face 53 of upside port 50 and extend the wall contacts of tube portion 31 under squeezed state.This is simple in construction effectively,
Accessory is few, and cost is low, has feasibility of efficiently constructing.
The lower outlet 52 of ball valve 5 axle in a state of use is entered in the upper water inlet 12 of threeway side recessed region valve 1 and threeway side
Heart direction is parallel, and this also has benefited from extending tube portion 31 and the Split type structure of ball valve 5 and above-mentioned soft sealing structure are entered in threeway side,
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, can also use internal thread, ring flange
Etc. attachment structure；Upper water inlet 12 and lower outlet 52 use slip-knot female thread structure in addition, can also use external screw thread, interior spiral shell
Other attachment structures such as line.
As shown in Fig. 2 the region valve element 13 of the threeway side recessed region valve 19 in the present embodiment is a up and down component
Part, its valve rod 18 are protruded outside valve body, and can be coordinated with electrical actuator 19.Electrical actuator 19 can be realized pair under signal
The keying of threeway side recessed region valve 19.
As shown in figure 3, the inner side of upside port 50 of ball valve 5 is entered in the threeway side in the present embodiment, O-ring 54 is placed provided with one
Annular groove 55, can realize and extend the sealing of the outer wall of tube portion 31, increase security and do not influence rotational positioning.
Fan coiler temperature controlled valve group as shown in Figure 4, including a threeway side recessed region valve 1, in threeway side recessed region valve 1
Downside port 10 connects a central cavity 3, is provided with central cavity 3 and enters upper valve for pressure difference core segment 30 only, and connects three
The upside port 50 of ball valve 5 is entered in logical side；Described threeway side is entered water inlet 51 under the left end of ball valve 5 and connected all the time with central cavity 3；
The upper water-out mouth 11 of the left end of threeway side recessed region valve 1 connects all the time with central cavity 3, and passes through region valve element 13 and upper water inlet
12 realize keying；The outer wall of described central cavity 3 is to extend tube portion 31, and extension tube portion 31 enters ball valve 5 with threeway side and divided
Body, and realize by hermetic unit 32 to extend tube portion 31 and enter with threeway side the sealing of ball valve 5 and fix.
Threeway side recessed region valve 1 is integrative-structure with extending tube portion 31, has preferable sealing property and less production
Product accessory, valve for pressure difference core segment 30, which is placed in, to be extended in the central cavity 3 of tube portion 31, and only lower logical installation direction, energy are real thereon
Existing overvoltage protection, a circulation loop is realized in fan coil front end, protects the pressure problems of too of right-hand member fan coil.
Under the invention normal operating condition, cold medium or thermal medium are entered by lower water inlet 51 from lower outlet 52
Enter the water inlet of fan coil, by internal pipeline from upper water inlet 12, then flowed out from upper water-out mouth 11, if lower water inlet 51
Pressure is excessive between upper water-out mouth 11, and the valve for pressure difference core segment 30 of central cavity 3 is opened, and medium directly enters from lower water inlet 51
Enter upper water-out mouth 11, realize medium circulation, protective conduit.
A kind of fan coiler temperature controlled valve group of the present invention, pressure differential cycles return line is realized in fan coil front end, is protected
Loine pressure balances；This other structure enters ball valve Split type structure using tube portion is extended with threeway side, specifically flexible roll adjustment function,
The problem of meeting different fan coil interface spacing connections；Change connected mode, black box cause site construction it is efficient and convenient,
