background technique
Stop valve is a kind of valve of commonly using, mainly by valve body, spool, valve rod and valve gap composition, valve body is provided with valve base, spool coordinates with valve base, realize sealing, it is commonly used on the drainage equipment of thermal power generation, serviceability temperature is generally all when (2000 0C left and right), what at this moment the pressure in device valve will become is very large, at this moment just very strong for the sealing requirements of valve body, if sealing is not good words in the situation that of this High Temperature High Pressure, high-temp liquid in valve pocket will eject easily, operator's life is brought safely to very large threat, traditional stop valve is all manually operated structure, the in the situation that of normal temperature and pressure, be still easy to operate, but the in the situation that of High Temperature High Pressure, just be difficult to operate, for this reason, we propose the good power plant of a kind of sealing high temperature pneumatic stopping valve.
Model utility content
The purpose of this utility model is to provide the good power plant of a kind of sealing high temperature pneumatic stopping valve, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: the good power plant of a kind of sealing high temperature pneumatic stopping valve, comprise handwheel, locker, neutral point spoon chi, barrier film, elasticity ramp, gas source inlet, proportioning valve, connecting rod, flap, high temperature water stopping plug, leakproof overhead-valve, valve body, valve casing and manual rod, described handwheel is connected with the manual rod that is positioned at valve casing cavity, and described manual rod is connected with elasticity ramp; The left side of described handwheel is connected with neutral point spoon chi, and described locker structure is arranged on the valve casing on handwheel right side; Described leakproof overhead-valve is positioned on the manual rod bar of stating elasticity ramp bottom, and described proportioning valve is positioned at the top of connecting rod, and described high temperature water stopping plug is positioned on connecting rod; Described flap is positioned at the bottom of connecting rod, and described valve body is positioned at the bottom of valve casing, and described gas source inlet is positioned on the valve shell cavity elasticity ramp lower right corner.
Preferably, there is an Aerodynamic Axis structure described elasticity ramp inside.
Preferably, described neutral point spoon chi can rotate with the rotation of handwheel, and is an index dial structure with pointer.
Preferably, on described handwheel, leave the locking draw-in groove of locker.
Preferably, the card article of the draw-in groove of described proportioning valve and leakproof overhead-valve is the structure fitting like a glove.
Preferably, described high temperature water stopping plug is structure movable up and down at connecting rod.
Preferably, the inner chamber of described valve casing leaves the sealed storage chamber of gas source inlet gas.
Working principle of the present utility model: the right water inlet place at valve body connects water source, if think throttle down, we need first to drive high temperature water stopping plug to move downward by manually-operable handwheel, be stuck between flap and valve body, reach preliminary seal action, because at this moment manual operation has just relatively been required great effort, then we can pressurize by gas source inlet in valve body chamber, drive high temperature water stopping plug to continue to move downward, in this process, leakproof overhead-valve also can move downward, be stuck on proportioning valve, to prevent that hot water from moving to top, overflow at handwheel place and scald operator.
Compared with prior art, the beneficial effects of the utility model are: the good power plant of sealing high temperature pneumatic stopping valve, adopt handwheel and Pneumatic Pressure to carry out throttle down, operator is lighter in the process of operation, and sealing effect is also better, its proportioning valve and leakproof overhead-valve structure greatly reduce, and the situation that hot water to upper reaches, easily overflows from handwheel has ensured operator's life safety.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, the good power plant of a kind of sealing high temperature pneumatic stopping valve, comprise handwheel 1, locker 2, neutral point spoon chi 3, barrier film 4, elasticity ramp 5, gas source inlet 6, proportioning valve 7, connecting rod 8, flap 9, high temperature water stopping plug 10, leakproof overhead-valve 11, valve body 12, valve casing 13 and manual rod 14, described handwheel 1 is connected with the manual rod 14 that is positioned at valve casing 13 cavitys, described manual rod 14 is connected with elasticity ramp 5, and there is an Aerodynamic Axis structure described elasticity ramp 5 inside; The left side of described handwheel 1 is connected with neutral point spoon chi 3, described neutral point spoon chi 3 can rotate with the rotation of handwheel 1, and be an index dial structure with pointer, described locker 2 structures are arranged on the valve casing on handwheel 1 right side, leave the locking draw-in groove of locker 2 on described handwheel 1; Described leakproof overhead-valve 11 is positioned on manual rod 14 bars of stating elasticity ramp 5 bottoms, described proportioning valve 7 is positioned at the top of connecting rod 8, the card article of the draw-in groove of described proportioning valve 7 and leakproof overhead-valve 11 is the structure fitting like a glove, described high temperature water stopping plug 10 is positioned on connecting rod 8, and described high temperature water stopping plug 10 is structure movable up and down at connecting rod 8; Described flap 9 is positioned at the bottom of connecting rod 8, and described valve body 12 is positioned at the bottom of valve casing 13, and described gas source inlet 6 is positioned on valve casing 13 inner chamber elasticity ramp 5 lower right corner, and the inner chamber of described valve casing 13 leaves the sealed storage chamber of gas source inlet 6 gases.
