Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is the utility model temperature control guided piston type steam bleeder structural representation.
Refer to Fig. 1, the temperature control guided piston type steam bleeder that the utility model provides, comprise water intake 24, valve gap 1, valve body 7, main valve seat 15 and water outlet 25, piston 19 is provided with in described valve body 7, described piston 19 to be located in piston-cylinder 18 and to be connected with piston rod 10, valve block 16 is provided with between described piston rod 10 and main valve seat 15, wherein, bi-metallic element 22 and inlet valve seat 2 is provided with between described water intake 24 and piston 19, described bi-metallic element 22 is connected with guide's valve rod 3, one end of described guide's valve rod 3 can fit with the sealing surface of inlet valve seat 2, the other end can fit with the sealing surface of delivery valve seat 4, described valve gap 1, inlet valve seat 2, closeding valve cavity is formed between piston 19 and delivery valve seat 4.
The temperature control guided piston type steam bleeder that the utility model provides, described delivery valve seat 4 is connected with water outlet 25 by connecting tube 6, described delivery valve seat 4 is provided with the first pressure cap 5 with the jointing of connecting tube 6, and described water outlet 25 is provided with the second pressure cap 12 with the jointing of connecting tube 6.Fixed by nut 8 between described piston 19 and piston rod 10 and be provided with the first seal ring 9, between described piston 19 and piston-cylinder 18, being provided with piston seal 20, between described piston rod 10 and piston-cylinder 18, being provided with the second seal ring 11.Described valve block is free state, and described piston rod 10 is connected by the 3rd pressure cap 17 with between valve block 16.Exhaust port 26 is provided with between described guide's valve rod 3 and delivery valve seat 4; Bi-metallic element 22 is fixed on water intake 24 place by plug screw 23, and water outlet 25 place is provided with bottom plug screw 13 and the first nut 14; Be fixedly linked by the second nut 21 between piston-cylinder 18 and valve body 7.
The temperature control guided piston type steam bleeder that the utility model provides, detailed process is as follows:
1) when drain valve is started working, condensed water enters from water intake, at this moment bi-metallic element 22 does not work, guide's valve rod 3 contacts with the sealing surface of inlet valve seat 2 and is in sealing state, guide's valve rod 3 and delivery valve seat 4 are in open mode, therefore the closeding valve cavity above piston 19 does not have pressure, make valve block 16 and main valve seat 15 be in open mode under the elastic force of piston 19 spring below piston 19 with the piston rod 10 be connected and valve block 16, such condensed water just can easily in valve pipeline 27 discharge from main valve seat 15.
2) when condensed water has soon flowed and lower than bi-metallic element 22, bi-metallic element 22 touches the high-temperature steam immediately following condensed water, at this moment the bimetallic strip expanded by heating that bi-metallic element 22 is built-in, and drive guide's valve rod 3 to move to illustrated right direction, while the sealing surface of first pilot stem 3 and inlet valve seat 2 is opened, guide's valve rod 3 contacts closedown with the sealing surface of delivery valve seat 4, steam enters the uuper valve chamber of piston 19 from inlet valve seat 2, because the cross-section area of piston 19 is much larger than the cross-section area of pipeline in valve 27, therefore piston 19 moves down under the vapor pressure effect more much bigger than spring force, and drive piston rod 10 and valve block 16 to move down simultaneously, until the sealing surface of valve block 16 touches the sealing surface of main valve seat 15, drain valve is closed.
3) when condensed water enters in drain valve again, bi-metallic element 22 touches condensed water, because condensate temperature is lower than steam, at this moment the bimetallic strip that bi-metallic element 22 is built-in shrinks, and drive guide's valve rod 3 to move to illustrated left direction, while first pilot stem 3 contacts sealing with the sealing surface of inlet valve seat 2, the sealing surface of guide's valve rod 3 and delivery valve seat 4 is opened, steam in piston 19 uuper valve chamber is discharged to drain valve outlet by the exhaust port on the right side of guide's valve rod 3 through connecting tube 6, at this moment piston 19 uuper valve chamber internal pressure is reduced to and does not have pressure, piston 19 drives piston rod 10 and valve block 16 to move up under the elastic force of spring, make the sealing surface of valve block 16 away from the sealing surface of main valve seat 15, open drain valve, at this moment condensed water again can easily in valve pipeline 27 discharge from main valve seat 15.Then drain valve constantly repeats above action.
Drain valve of the present utility model is connected with guide's valve rod by arranging bi-metallic element, guide's valve rod is utilized to control the knee-action of control piston, the opening and closing of further control valve block and main valve seat, stable performance, safe and reliable, need not built-in filter screen, but drain valve forward filtering net can be adopted, so not only can reduce the volume of drain valve, filter screen can also be unpicked and washed eaily.Valve seat orifice due to main valve seat 15 of the present utility model can be worked into the size of tens millimeters, therefore a few to tens of times larger than existing drain valve valve seat orifice several millimeters even size of tens millimeters, so the discharge capacity of this temperature control guided piston type steam bleeder is large especially.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
