Summary of the invention
The invention provides a kind of bowl-type valve core frame bimetal drainage valve, object is that the T-shaped valve core frame bimetal drainage valve volume solving existing use is large, the problem of Heavy Weight.
Valve gap 1 and valve body 6 are still connected by bolt by bowl-type valve core frame bimetal drainage valve, valve body 6 with valve inlet 11 be in same axis with valve export 9 and vertical with valve core axis; Valve core frame is bowl-type valve core frame, and bowl-type valve core frame is by two set screws through bowl-type valve core frame bottom surface and valve body internal fixtion, and the line of centres of described two set screws and the center line of valve inlet and valve export tilt staggered mutually; The Spool assembly be made up of adjusting nut 2, bimetallic strip assembly 4 and cue stick components 7 is arranged on bowl-type valve core frame 5.Valve core frame two set screws of such bowl-type valve core frame bimetal drainage valve can be selected the position of a week, according to the position that valve body is abundant, fixing screw hole is set, two set screw lines of centres enter with valve body-and center line of discharge does not need mutually vertical, and two axial lines can be arbitrarily angled.
Described two axial lines can in arbitrarily angled desirable 35 ° ~ 55 °.
Described Spool assembly is made up of adjusting nut, bimetallic strip assembly and cue stick components; Simple-beam type rectangle bimetallic strip assembly is arranged on valve core frame; Cue stick components bottom is globe disk, relative with the floss hole of valve core frame, and middle part is that valve rod passes bimetallic strip assembly, and top connects adjusting nut.
Described bimetallic strip assembly is made up of one group, two groups or three groups of bimetallic strips; Each group can have one or more pieces bimetallic strips.
Described valve bowl-type spool erection has three different depths and bimetallic strip with wide groove, places one group, two groups or three groups of bimetallic strip assemblies respectively.
The groove of described valve core frame three different depths, mutually in 60 degree of angles.
Described pipeline type drain valve valve gap and valve body Connecting format one are welding, and another kind of is bolt connection.
The present invention and existing conventional bimetal drainage valve T-shaped valve core frame used, bimetal drainage valve compares and has the following advantages:
1., owing to adopting bowl-type structure, volume is little, lightweight.
2., owing to adopting globe disk, ball face sealing self-alignment, valve under the unrestricted condition in mounting point, normally can work.
3., owing to adopting rectangle bimetallic strip, make full use of longitudinal performance that bimetallic strip is excellent.
4. (being heated and producing hot-drawn power) when bimetallic strip works in its assembly, is linear contact lay each other, in theory without friction, can not lose hot-drawn power because of friction.
5. valve core frame is provided with 3 different depths and bimetallic strip with wide groove, makes bimetallic strip keep correct working position.

Picture in picture mark illustrates: valve gap 1, adjusting nut 2, bolt 3, bimetallic strip assembly 4, valve core frame 5, valve body 6, cue stick components 7, floss hole 8, valve export 9, filter screen 10, valve inlet 11.
Embodiment
The present invention is described in detail below.
Fig. 2, is bowl-type valve core frame bimetal drainage valve of the present invention, has valve gap 1, valve body 6, valve core frame and Spool assembly.Valve gap 1 and valve body 6 connect by bolt, valve body 6 with valve inlet 11 and valve export 9 be in same axis, vertical with valve core axis; Valve core frame is bowl-type valve core frame, and bowl-type valve core frame is fixed through in bowl-type valve core frame bottom surface and valve body above by two set screws, and two set screw lines of centres and valve body enter-and center line of discharge tilts staggered mutually; The Spool assembly be made up of adjusting nut 2, bimetallic strip assembly 4 and cue stick components 7 is arranged on bowl-type valve core frame 5.Described bimetallic strip assembly is made up of one group, two groups or three groups of bimetallic strips, is preferably made up of three groups of bimetallic strips; Each group can have one or more pieces bimetallic strips.Valve inlet 11 and valve export 9 coaxial line, medium condenses water or gas are entered in drain valve by valve inlet 11 and flow through bimetallic strip assembly 4, cue stick components 7, floss hole 8, flow out valve by valve export 9.The medium condenses water flowed into or the temperature of gas change, first be that bimetallic strip in first group of groove bends when temperature is raised, hot-drawn power is produced by reconciling nut 2 pairs of cue stick components 7, cue stick components 7 moves, temperature continues to rise, bimetallic strip in second group and the 3rd group of groove produces hot-drawn power to cue stick components 7 successively, causes the globe disk of cue stick components 7 bottom progressively to close the floss hole 8 of valve core frame 5 bottom; When temperature rises to setting condensed water stopping exhaust temperature, the hot-drawn power stacking value that three groups of bimetallic strips produce, closes the floss hole 8 of valve core frame 5 bottom completely.
In Fig. 4, bowl-type valve core frame has three different depths and bimetallic strip with wide groove: three groups of bimetallic strips are positioned at wherein successively, guarantees the working position that bimetallic strip is correct.
Bimetallic strip assembly independently acts on the valve rod of cue stick components by thermogenetic hot-drawn power, and attempt makes bimetal drainage valve stop discharge.Each bimetallic strip group participates in work successively according to the pressure range of bimetal drainage valve application, makes bimetal drainage valve discharge the temperature curve (actual is broken line) of solidifying water, is close with saturated-steam temperature curve.
Major parameter:
Maximum operating pressure: be respectively 0.35MPa, 1.4MPa, 2.8MPa;
Maximum operation (service) temperature: be respectively 260 DEG C, 454 DEG C.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
