Abstract
The utility model discloses a high-temperature high-pressure-steam hydrophobic valve belonging to the field of valves. The high-temperature high-pressure-steam hydrophobic valve comprises a valve body, a valve seat and a valve rod fixed at the lower part of the valve body, a valve clack connected with the lower part of the valve rod, a valve cover connected with the upper part of the valve body, and a filler pressing sleeve and a filler pressing plate connected above the valve cover, wherein hard alloy layers are overlaid on the valve seat and the valve clack. The high-temperature high-pressure-steam hydrophobic valve is mainly used for high-temperature high-pressure-steam hydrophobe.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of high temperature and high pressure steam hydrophobic valve.
Background technique
The high temperature and high pressure steam hydrophobic valve is mainly used in each hydrophobic place of fired power generating unit steam pipe system, plays the effect of the water of condensation of each system of quick drain.Flap in the valve body moves under the drive of Pneumatic actuator and valve rod, and the applying that makes flap and valve base sealing is finished the work with separating.Therefore the sealing stability of Pneumatic actuator and flap assembly is most important, directly influences the working life of valve.
The main structure and the shortcoming of valve are at present: the sealing surface of flap and valve seat is not the whole hard alloy sealing, easily by the steam erosion, causes valve short working life; Filler on the valve gap damages to cause easily under action of high temperature and leaks outside; The diaphragm type Pneumatic actuator is the easy overheating failure of film at high temperature, causes the valve can't opening and closing.
The model utility content
The utility model technical problem to be solved provides the high temperature and high pressure steam hydrophobic valve of a kind of reasonable in design, long service life.
The utility model adopts following technological scheme: the high temperature and high pressure steam hydrophobic valve; Comprise valve body; Be fixed on valve seat, the valve rod of valve body lower portion, be connected the flap of stem lower portion, be connected the valve gap on valve body top; Be connected filler gland, the hold-down grid of valve gap top, said valve seat and flap built-up welding have hard alloy layer.
Further, offer guiding groove on the said flap.
Further, offer radiating fin on the said valve gap.
Further, said radiating fin is an annular fin.
The utility model compared with prior art has following advantage:
1, valve seat and flap sealing surface are designed to whole pile-up welding hard alloy layer, have increased the reliability and the serviceability of sealing like this.
2, on flap, offer guiding groove, make that its sealing stability is better.
3, design annular fin on the valve gap, reduced the temperature at filler place and diaphragm type Pneumatic actuator place, avoided filler under action of high temperature, to damage easily to cause and leaked outside and the easy overheating failure of film, cause the valve can't opening and closing.
4, the utility model reasonable in design, durability is outstanding.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, reference character: 1 is valve body, and 2 is valve seat, and 3 is valve gap, and 4 is flap, and 5 is valve rod, and 6 is the filler gland, and 7 is hold-down grid.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1; The high temperature and high pressure steam hydrophobic valve; Comprise valve body 1, be welded on valve seat 2, the valve rod 5 of valve body 1 bottom, be connected the flap 4 of valve rod 5 bottoms, the valve gap 3 that is connected valve body 1 top, the filler gland 6 that is connected valve gap 3 tops, hold-down grid 7; Valve seat 2 has hard alloy layer with flap 4 built-up welding, as adopting hard alloy overlay welding.So just can increase the reliability and the serviceability of sealing.
For valve rod 5 is being moved driving under the effect of Pneumatic actuator on the flap 4, thereby open valve rapidly, flap 4 cooperates the formation conical surface seal with valve seat 2.
In order to increase sealing stability, on flap 4, offer guiding groove.
In order to have reduced the temperature at filler place and diaphragm type Pneumatic actuator place; Having avoided filler under action of high temperature, to damage easily to cause leaks outside and the easy overheating failure of film; Cause the valve can't opening and closing, on valve gap 3, design radiating fin, radiating fin adopts annular fin.
As stated, just can realize the utility model preferably.
Claims (4)
1. high temperature and high pressure steam hydrophobic valve; Comprise valve body; Be fixed on valve seat, the valve rod of valve body lower portion, be connected the flap of stem lower portion, be connected the valve gap on valve body top; Be connected filler gland, the hold-down grid of valve gap top, it is characterized in that: said valve seat and flap built-up welding have hard alloy layer.
2. high temperature and high pressure steam hydrophobic valve according to claim 1 is characterized in that: offer guiding groove on the said flap.
