Abstract
Control valve can preset. Solved mainly that current control valve can not be adjusted in advance and controlled temperature inaccuracy ground problem. Including valve body, case, adjusting ring, water outlet pipe, loose joint nut and sealing washer. Case and adjusting ring lie in the valve body, seal and water outlet pipe connection, its characterized in that are encrypted through the loose joint nut in the valve body right side: valve left side be equipped with the import pipe, import pipe and valve body formula structure as an organic whole, outlet pipe and valve body left side junction be equipped with the soft seal circle, use this sealing washer to make the sealed effect of control valve promote, also become simply at assembling process moreover, the adjusting ring in the valve body, the adjusting ring is equipped with the flow groove corresponding with the flow, the relative position through regulated flow groove and outer metering orifice presets valve flow's size.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of predeterminable control valve of determining.
Background technology
Temperature control valve is applicable to steam, hot water, deep fat etc. for the various thermal conditions of medium, be widely used in heating, air-conditioning,Temperature in domestic hot-water regulates automatically, and the temperature of special operation condition regulates automatically.
Common existing temperature control valve comprises valve body sub-assembly, is made up of spool, valve body and loose joint nut. But needWant manual adjustments, and cannot preset the size of flow, such valve body inconvenient operation, and also the precision of controlling is notHigh; The inlet tube of existing valve body is split type, bothers like this for the assembling of valve body, and sealing property is also bad.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of predeterminable control valve of determining, and mainly solvesExisting control valve flow can not preset, assembling inconvenience and the bad problem of air-tightness.
The technical solution adopted in the utility model is: predeterminablely determine control valve, comprise valve body, spool, adjusting ring, outletAnd loose joint nut, described spool is positioned at valve body, and adjusting ring is positioned at below valve body inner spool, and valve body passes on left loose joint spiral shellCap is connected with outlet, and described valve body right side is provided with inlet tube, and described inlet tube and valve body are integral type structure; DescribedOutlet and junction, valve body left side are provided with sealing ring, and described sealing ring is flexible glue O type circle.
In described spool, be provided with valve rod, have adjusting ring below spool, between described spool and adjusting ring, be provided with spring,Listen the valve rod lower end of stating to be provided with hotness contact.
Described valve body end face indicates corresponding Digital ID, in the time that valve rod drives adjusting ring to rotate, and the flag of valve rodPut corresponding with numeral.
Described adjusting ring has five flow channel, and area diminishes clockwise successively, and the flow being passed through also diminishes successively.
This practical beneficial effect is: owing to taking such scheme, sealing has improved, and assembles simple; Importantly beMatch with adjusting ring flow channel by outflow metering-orifice, make this control valve can preset flow, the precision of automatically controlling is largeImprove greatly.

Fig. 3 is adjusting ring structural representation.
Fig. 1 comprises 1, spool nut 2, sealing ring 3, valve rod 4, spool main body 5, spool valve body connect sealing ring 6, adjusting ring7, sealing piece 8, valve body 9, outlet 10, outlet pipe are connected sealing ring 11, loose joint nut 12, snap ring 13, hotness contact with valve body14, spring 15, snap ring.
Fig. 2 comprises 1, spool nut 2, sealing ring 3, valve rod 4, spool main body 5, spool valve body connect sealing ring 6, adjusting ring7, sealing piece 8, valve body 9, outlet 10, outlet pipe are connected sealing ring 11, loose joint nut 12, snap ring 13, hotness contact with valve body14, spring 15, snap ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1 with Figure 2, preset temperature-sensing valve, comprise valve body 8, spool forms by 1,2,4,5,7,12, outlet9, and loose joint nut 11, described spool is positioned at valve body 8, and valve body 8 passes on left loose joint nut 11 and is connected with outlet 9,Described valve body 8 right sides are provided with inlet tube, and inlet tube and described valve body 8 are integral type structure, compare original split-type structural, shouldValve installation is more simple, and intensity and bending resistance are better, and sealing effectiveness is better; Described outlet 9 is connected with valve body 8 left sidesPlace is provided with O RunddichtringO 10 and compares better tightness with original hard sealing, assembles simpler.
Described spool has adjusting ring 6, is provided with valve rod 3 in adjusting ring 6 and spool, described spool and adjusting ring 6 itBetween be provided with spring 14, described valve rod 3 lower ends are provided with hotness contact 13. Controlled medium changes by hotness contact 13 sense temperature,Liquid volume in valve body 8 is along with variations in temperature expands or shrinks. Controlled medium temperature is higher than when setting value, and expansion of liquids, pushes awayOvable valve stem 3 moves downward, and valve-off reduces heat flow; Controlled medium is lower than when setting value, liquid contraction, and spring 14 promotesValve rod upwards, increases heat flow. Rotation valve rod 3 makes the flow channel of five different area of adjusting ring 6 and valve body 8 metering-orifice that outflowsPosition changes, and presets the size of flow, then coordinates temperature controller to use, and has so just realized automatic control, accurately control,Reach ideal effect.
Described valve rod 3 tops have mark groove, and valve body 8 end faces are provided with respective digital mark, because adjusting ring 6 is at valve body 8Inside, operating personnel do not see in the time presetting flow, so valve body 8 end faces are provided with numeral, operating personnel can be passed throughNumeral just can preset flow.
Each technical staff notice: although the utility model describe according to above-mentioned detailed description of the invention, this practicalityNovel invention thought is not limited in this utility model, and the repacking of any utilization inventive concept all will be included this patent in specialIn economic rights protection domain.
