The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is temperature control guided piston type steam bleeder structural representation of the present invention.
Refer to Fig. 1, temperature control guided piston type steam bleeder provided by the invention, including water inlet 24, bonnet 1, valve
Body 7, main valve seat 15 and delivery port 25, are provided with piston 19 in the valve body 7, the piston 19 be located in piston-cylinder 18 and with work
Stopper rod 10 is connected, and valve block 16 is provided between the piston rod 10 and main valve seat 15, wherein, between the water inlet 24 and piston 19
Provided with bi-metallic element 22 and inlet valve seat 2, the bi-metallic element 22 is connected with guide's valve rod 3, and the one of guide's valve rod 3
End can fit with the sealing surface of inlet valve seat 2, and the other end can fit with the sealing surface of delivery valve seat 4, the bonnet 1, enter
Closeding valve cavity is formed between air valve seat 2, piston 19 and delivery valve seat 4.
Temperature control guided piston type steam bleeder provided by the invention, the delivery valve seat 4 pass through connecting tube 6 and delivery port
25 are connected, and the delivery valve seat 4 and the interface of connecting tube 6 are provided with the first pressure cap 5, and the delivery port 25 connects with connecting tube 6
The second pressure cap 12 is provided with mouthful.Fixed between the piston 19 and piston rod 10 by nut 8 and be provided with the first sealing ring 9, institute
State and piston seal 20 is provided between piston 19 and piston-cylinder 18, second is provided between the piston rod 10 and piston-cylinder 18
Sealing ring 11.The valve block is free state, is connected between the piston rod 10 and valve block 16 by the 3rd pressure cap 17.The elder generation
Steam vent 26 is provided between pilot stem 3 and delivery valve seat 4；Bi-metallic element 22 can be fixed at water inlet 24 by plug screw 23,
The nut 14 of bottom plug screw 13 and first is provided with delivery port 25；Can be solid by the second nut 21 between piston-cylinder 18 and valve body 7
It is fixed to be connected.
Temperature control guided piston type steam bleeder provided by the invention, detailed process are as follows：
1）When drain valve is started working, condensed water enters from water inlet, and at this moment bi-metallic element 22 does not work, guide's valve rod
3 and the sealing surface contact of inlet valve seat 2 be in sealing state, guide's valve rod 3 and delivery valve seat 4 are in open mode, therefore work
The closeding valve cavity of the top of plug 19 does not have pressure, the spring below piston 19 with the piston rod 10 and valve block 16 being connected of piston 19
Elastic force under make valve block 16 and main valve seat 15 is in open mode, such condensed water just can easily by pipeline 27 in valve from
Discharged at main valve seat 15.
2）When condensed water has soon flowed and is less than bi-metallic element 22, bi-metallic element 22 is touched immediately following condensed water
High-temperature steam, at this moment the bimetal leaf expanded by heating built in bi-metallic element 22, and drive guide's valve rod 3 to the right side side of diagram
To movement, while the sealing surface of first pilot stem 3 and inlet valve seat 2 is opened, the sealing surface of guide's valve rod 3 and delivery valve seat 4
Contact is closed, and steam enters the uuper valve chamber of piston 19 from inlet valve seat 2, because the cross-sectional area of piston 19 is much larger than pipeline in valve
27 cross-sectional area, therefore piston 19 moves down under the steam pressure effect more much bigger than spring force, and drive simultaneously
Piston rod 10 and valve block 16 move down, and until the sealing surface of valve block 16 touches the sealing surface of main valve seat 15, close drain valve
Close.
3）When condensed water is again introduced into drain valve, bi-metallic element 22 touches condensed water, due to condensate temperature ratio
Steam is low, and at this moment the bimetal leaf built in bi-metallic element 22 shrinks, and drives guide's valve rod 3 to be moved to the left direction of diagram
It is dynamic, while the sealing surface contact of first pilot stem 3 and inlet valve seat 2 seals, the sealing surface of guide's valve rod 3 and delivery valve seat 4
To open, the steam in the uuper valve chamber of piston 19 is discharged to hydrophobic valve outlet by the steam vent on the right side of guide's valve rod 3 by connecting tube 6,
At this moment the upper valve cavity pressure of piston 19 is reduced to no pressure, elastic force lower band piston bar 10 and valve block of the piston 19 in spring
16 move up, and make sealing surface of the sealing surface of valve block 16 away from main valve seat 15, open drain valve, and at this moment condensed water and can is held very much
Easy discharges by pipeline 27 in valve at main valve seat 15.Then drain valve constantly repeats to act above.
The drain valve of the present invention is controlled to control by setting bi-metallic element to be connected with guide's valve rod using guide's valve rod
The up and down action of piston, further controls the opening and closing of valve block and main valve seat, stable performance, securely and reliably, without built-in screen pack,
But drain valve forward filtering net can be used, it so can not only reduce the volume of drain valve, can also eaily unpick and wash
Screen pack.Because the valve seat orifice of the main valve seat 15 of the present invention can be worked into tens millimeters of size, therefore than existing drain valve
A few to tens of big times of size that even more than ten millimeters of several millimeters of valve seat orifice, so this temperature control guided piston type steam bleeder
Discharge capacity is especially big.
Although the present invention is disclosed as above with preferred embodiment, so it is not limited to the present invention, any this area skill
Art personnel, without departing from the spirit and scope of the present invention, when a little modification and perfect, therefore the protection model of the present invention can be made
Enclose to work as and be defined by what claims were defined.
