For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 1 is the structural representation of the utility model embodiment invert barrel drain valve.As shown in Figure 1, the invert barrel drain valve that this example provides comprises valve body 11, the top of valve body 11 is provided with valve gap 12, below is provided with drain sump 13, valve body 11 is communicated with valve gap 12 but is separated by dividing plate 14 with between drain sump 13, invert barrel 15 is provided with in valve body 11, steam inlet pipe 16 and intake pipe 17 is provided with in invert barrel 15, steam inlet pipe 16 and intake pipe 17 all enter in drain sump 13 through dividing plate 14, and are provided with in drain sump 13 and can rise along with the water level in drain sump 13 or decline and the shutoff cup 18 of shutoff or relieving steam inlet pipe 16.
Owing to there being the unique design of shutoff cup 18, as long as therefore there is water of condensation to enter drain sump 13, shutoff cup 18 will float the steam inlet blocking steam inlet pipe 16, ensure that water of condensation is first disposed in invert barrel 15 by intake pipe 17, now invert barrel 15 decline is opened valve nozzle assembly 19 and is carried out hydrophobic, discharges water of condensation and the fundamental function as far as possible preventing steam leakage to realize drain valve; When the condensation water level in drain sump 13 declines, shutoff cup 18 decontrols steam inlet pipe along with water level decreasing, and now steam can enter invert barrel 15 by steam inlet pipe 16, and invert barrel 15 rises cut-off valve nozzle assembly 19, stops draining also to prevent steam leakage.This structure of drain valve can assemble some water of condensation all the time in the drain sump 13 of bottom and valve body 11, the fresh steam of entering is surrounded by water of condensation all the time, realize the water seal (water seal is here different from the water seal at the valve nozzle assembly place of general drain valve indication) of steam, prevent fresh steam from leaking.
Because the drain valve in the present embodiment can accumulate some water of condensation in valve pocket inside, and can to remaining water seal, therefore most of cavity 11 in valve pocket, valve gap 12 and drain sump 13 all contact with water of condensation, the temperature of water of condensation is no more than 100 DEG C, because water of condensation has cooling action, therefore the temperature of drain valve not only can not be made to raise by the superheated vapor of water seal in valve pocket, and can slowly condense, thus be as good as under ensure that the serviceability temperature of drain valve self and general pressure, as long as the valve of drain valve meets pressure requirements, this drain valve just can at high temperature, high pressure, Long-Time Service under the operating mode of Smaller load.
In heating plant or steam line, there is less water of condensation to produce under general High Temperature High Pressure overheat condition, at this moment can adopt this series products that the present embodiment provides.The invert barrel Automatic steam trap Trap Maximum operating pressure of the band drain sump that the present embodiment provides can reach 105bar, and Maximum operating temperature can reach 454 DEG C, and maximum pump discharge is 430kg/h, meets the demand of overheat condition completely.

It should be noted that, under the projection state shown in Fig. 1, the position of steam inlet pipe 16 and intake pipe 17 overlaps, and namely intake pipe 17 will be blocked by steam inlet pipe 16 and invisible.But in order to make intake pipe 17 to reveal, in Fig. 1, the position of intake pipe 17 being changed, making it to overlap with the position of import honeycomb duct 20.In fact, steam inlet pipe 16, intake pipe 17 and import honeycomb duct 20 are spatially arranged, the bottom pipe schematic diagram after the removal drain sump shell that its arrangement can be shown in Figure 2.
In the embodiment shown in Fig. 1 and Fig. 2, the hydrophobic process of this invert barrel drain valve is specific as follows:
As shown in Figure 3A, under the first state that invert barrel drain valve is hydrophobic, the mixture of condensation water and steam enters drain sump 13, now shutoff cup 18 rises and shutoff steam inlet pipe 16 with water level under the effect of buoyancy, water of condensation from intake pipe 17 enter invert barrel 15 and and then enter valve body 11, invert barrel 15 sinks, and drives leverage to open draining valve nozzle, starts draining.
As shown in Figure 3 B, under the second state that invert barrel drain valve is hydrophobic, the mixture of condensation water and steam continues to enter drain sump 13, but the water level decreasing after draining before in drain sump 13, now the shutoff cup 18 of shutoff steam inlet pipe 16 falls, and steam tube 16 is opened and made steam enter invert barrel 15.
As shown in Figure 3 C, under the third state that invert barrel drain valve is hydrophobic, the mixture of condensation water and steam continues to enter drain sump 13, drain sump 13 still keeps lower water level, now shutoff cup 18 is still in the position fallen, and steam continues through steam inlet pipe 16 and enters invert barrel 15, and invert barrel 15 rises under the effect of steam, drive leverage cut-off valve nozzle assembly, stop draining.
As shown in Figure 3 D, under the third state that invert barrel drain valve is hydrophobic, the mixture of condensation water and steam continues to enter drain sump 13, when water of condensation water level in drain sump raises gradually, shutoff cup 18 floats and shutoff steam inlet pipe 16 again, preferentially make water of condensation enter in invert barrel 15 by intake pipe 17, start the hydrophobic cycle period of a new round.
Refer again to shown in Fig. 1, in the invert barrel drain valve that above-described embodiment provides, the top of invert barrel 15 is provided with hole, is equipped with pin 21 in this hole, and one end of pin 21 is provided with curved part, the bending rear formation knotting portion of the other end.Specifically, when pin 21 is through Kong Zhonghou, its crooked position is in the outside of invert barrel 15, and its knotting portion is positioned at the inside of invert barrel 15.In the mixture entering the condensation water and steam in drain sump 13 and valve body 11, inevitably be mingled with some non-condensible gases as air, the hole at invert barrel 15 top is mainly used to discharge these incoagulable gas, inevitably carries the steam of trace inside the air of certainly discharging secretly.After the air being entrained with steam is discharged into the top of valve gap 12, these steam can slowly can condense under the encirclement of water of condensation, are discharged afterwards with the form of water of condensation again.Pin 21 is made up of Stainless Steel Wire, and it can be movable along with the knee-action of invert barrel 15, prevents the hole at invert barrel 15 top from being blocked by dirt.
