18,19 bimetallic strips, 20 post piece shells, 22 bimetal frame lower discs, 23 handwheel locking nuts, 24 sealing gaskets, 25 sealing gaskets.

Fig. 2 is that the B of plan view is to partial sectional view.2 bimetal framves among the figure, 3 drift bolts, 12 valve rod outer sleeves, 21 oval mouthfuls.

Fig. 3 is the A-A sectional view of plan view bimetal frame.5 valve rods among the figure, 12 valve rod overcoats, 19 bimetallic strips, 22 bimetal frame lower discs.

Below in conjunction with accompanying drawing embodiment of the present utility model is illustrated:

The utility model is equipped with housing (11) on valve seat (8), form bimetal chamber (18) in housing, is equipped with valve stifled (1) in indoor valve rod (5) valve rod (5) bottom that is equipped with of bimetal, and the valve nozzle (16) that is used for opening on the valve seat is used.Be slidingly matched on the valve rod (5) valve rod outer sleeve (12) is housed, on outer sleeve (12), be bolted with bimetal frame (2) and adjust the position, bimetal frame lower disc (22) is locked on the outer sleeve (12) by metal frame tightening nut (14).Disk on the bimetal frame (17) is located, and goes up symmetry at outer sleeve (12) and has drift bolt (3) that two oval mouthful (21) and valve rod be fixed on one and can drive valve rod at oval mouthful of place and move up and down.Be bolted with and adjust handwheel (4) zero point, adjust when installing the position on outer sleeve top with handwheel locking nut (23) locking, the locking back adjusts handwheel and outer sleeve becomes one, drive outer sleeve and bimetal frame rotate together when rotating the adjustment handwheel, and the last disk of bimetal frame can be adjusted the mutual alignment between the range cylindrical piece in valve rod and the range rotating bracket (13) by the drift bolt that is fixed on the valve rod like this.Range rotating bracket (13) is to be screwed onto to adjust on the handwheel (4), and two range cylindrical pieces (6) that weight does not wait are housed on the post piece shell (16) of range rotating bracket.

The versatility of this STEAM TRAP is very strong, can according to install the condensation water quantity that produces in the warming pipeline how much, the size of vapor tension, the variation of weather, by adjusting the characteristic of adjusting handwheel (4) and range rotating bracket (13) and bimetallic strip (19) zero point, be adapted to various warming pipeline ， And and can reach safe and reliable.Be performed such in proper order during installation, valve stifled (1) is on the position of cut-off valve nozzle (16), drive outer sleeve (12) and bimetal frame (2) by adjusting handwheel (4) zero point then, (it is locked by the tight split nut of handwheel to adjust handwheel zero point, outer sleeve during rotation hand wheel (12) is rotation and then) disk on the bimetal frame (17) is close on the position of drift bolt (3), adjust the relative position of valve rod (5) and range garden post piece (6) by adjusting handwheel (4) and range rotating bracket (13) afterwards, just to the negative certain weight of valve rod, overcome because vapor pressure in the pipeline makes valve block up (1) greatly and be in the state of often opening.After STEAM TRAP inserts pipeline, being on the increase under normal situation along with the vapor condensation water yield, condensed water enters fluid input (9) and arrives valve nozzle (16) along with the continuous increase of condensation water quantity is increasing to the active force of valve stifled (1) by filter screen (7), up to valve stifled (1) is opened, condensed water sprays from valve nozzle (16), release by fluid output (10) then, condensed water releases the stifled gravity by self of back valve, again nozzle is blocked up, should block up the state that (1) is in start or stop up and down reciprocatingly all the time by maintaining valve under the general normal situation.

Want in the warming pipeline of warming equipment vapor tension bigger, need to install the bigger STEAM TRAP of range.After pacifying, the STEAM TRAP that range is little will make valve stifled (1) be in the state of often opening, so just certainly will waste more energy, the utility model is because range is adjustable, make post piece shell (20) center pillar piece (6) just in time can make valve stifled (1) enter normal fluctuation status up and down to the heavy burden that valve blocks up (1) by adjustment, so not only preserved ducted energy and also can in time condensed water have been discharged from being in the position of often opening by valve rod (5).

Another related characteristics of the utility model are to be in when undesired when pressure in the pipeline, the vapor pressure fluctuation is bigger, especially northeastward the local climate difference variation is big, the vapor tension fluctuation is just bigger, sometimes vapor tension is in closed condition for a long time, causes a large amount of the accumulating of condensed water the stifled less such valve of active force stifled (1) of valve, can not discharge in time, cause the mobile not smooth of steam line, cause freezing of STEAM TRAP sometimes in the winter time.In the utility model since adopted bimetal frame (2) structure run under the above-mentioned situation bimetal chamber (18) because and atmosphere directly logical, under the situation that valve stifled (1) cuts out for a long time, the indoor temperature of bimetal has fallen soon, 4 bimetallic strips (19) on the bimetal frame meet open at once after cold (stretching) so the last disk (17) of bimetal frame hold up drift bolt (3) and drive valve rod (5) and open stifled (1) condensed water discharge from valve nozzle (16) of valve and make STEAM TRAP recovery proper functioning like this, got rid of the hidden danger of freezing.

It is that the resistance that reduces fluid output is discharged the condensed water of discharge unblockedly from fluid output greater than the diameter purpose of valve nozzle that this STEAM TRAP has been taked fluid output diameter (10).

Because so the present invention possesses These characteristics and will compare with steam trap of the same type, has highly versatile, safe and reliable, simple in structure, adjust saving manpower easy to maintenance, long service life, the advantages such as energy savings, this steam trap manufacturing process is simple, material is very common, cost is low is a kind of Novel steam trap that is popular in practical application.
