and steel ball are movingly, and effect is: with Boilor check valve seat 2 sealings, prevent the working medium backflow when steel ball 3 is fallen.The lower side of blind hole communicates with working medium inlet hole 35, its aperture is less than steel ball size, Boilor check valve seat 2 upper sides are arranged with 4 working medium exit orifices 38, its effect is: avoid the working medium of high temperature, high pressure directly to impact well-bucket 5, plug screw 4 is housed above the upper end hole of blind hole, and employing is threaded and welds.
The utility model working principle is such: work as lever piston bucket type high pressure steam drainage valve, be installed on the pipeline after, start working automatically as Fig. 9,10,11,12 signal.When steam passes through working medium inlet hole 35, enter Boilor check valve seat 2, back down steel ball 3, this moment, well-bucket 5 was in the bottom of valve body 1, and main valve seat 25 is opening state, and low-temperature condensate discharges rapidly, meanwhile discharged air (seeing accompanying drawing 9).When low-temperature condensate drains soon, steam is full of well-bucket 5 inner chambers, after well-bucket 5 inner chamber tops are filled the vapour height and are surpassed that the equalising torque attitude is required and fill the vapour height, the suffered buoyancy of well-bucket 5 is greater than gravity, well-bucket 5 quickens to rise, driving fixed pivot lever 16 driving auxiliary valve cores 26 moves upward, behind the 60 ° of conical surface Contact Pair valve seat of valve guide 27 tops, at this moment auxiliary valve core 26 is the 0.9mm stroke from closed position, glade plane space is 0.4mm, auxiliary valve core 26 under the effect of pressure medium, utilizes 60 ° of conical surface self-alignments in adsorption force that condensed water in high temperature flows out at a high speed and valve body 1 under the effect of inertia that moves upward, automatically close the hole of auxiliary-seat, promoting main valve plug 23 simultaneously closes with main valve seat 25, valve is closed condition, and steel ball 3 falls and Boilor check valve seat 2 sealings, (seeing accompanying drawing 10).Along with well-bucket 5 inner chamber steam reduce, buoyancy descends and sinks, at this moment auxiliary-seat a (60 ° of taper holes of main valve plug 23 inner chambers are auxiliary-seat) opens, and main valve seat 25 is still closed under the pressure of the c of cylinder chamber (main valve plug 23 inner chamber macropores), and valve is little displacement condition (seeing accompanying drawing 11).Along with well-bucket 5 steam inside reduce, condensed water in high temperature increases, and buoyancy reduces and sinks.Back seal b (gland 18 tops are close in the major diameter bottom surface of secondary valve connecting rod 17) closes (see figure 7), aperture 41 on the little valve gap 24 communicates with the c of cylinder chamber (main valve plug 23 inner chamber macropores) at this moment, make main valve plug 23 tops be in the effect of vapor pressure and sink, open main valve seat 25 holes, steel ball 3 rises and opens Boilor check valve seat 2, valve is in big displacement condition, enters new circulation work automatically (seeing accompanying drawing 12).
In sum: the utility model employing working medium substantially horizontal is advanced from valve body 1 downside water inlet 35, the angie type housing of the direction discharge straight up from valve gap top, has made things convenient for user's pipe arrangement to install.Utilize 60 ° of conical surface self-alignments, close two valve seat orifice automatically, the automatic closing system (see figure 6) is the error of compensating lever mechanism generation automatically, the rigid collision that produces when avoiding closing, make auxiliary valve core 26 in closing closed procedure, have buffer function, reduced the wearing and tearing of auxiliary valve core 26, auxiliary-seat, increased the service life, drain valve has been used close after initial stage and the wearing and tearing all very reliable, and switch motion is very sensitive, at pressure reduction less than also can regular event under the 0.01MPaG.
Plunger designs becomes the new piston mechanism of leading type, makes piston two-way lifting surface area ratio greater than 80, and the valve opening force that increases valve is more than 80 times.Well-bucket weight and size should satisfy fills the vapour height in the moment equilibrium state well-bucket and is not less than 140mm under Maximum differential pressure, fill vapour height allowance and be not less than 180mm in Minimum differntial pressure 0.05MPaG equalising torque attitude well-bucket.And the piston area that adopts in the utility model ratio is (56
2-6
2)/6
2=86.1, therefore increasing the main valve plug valve opening force reaches 86 times, has guaranteed that the drain valve action is normal under operating pressure differential 19MPaG high parameter, the reliability height.The weight of well-bucket 5 is 2200 ± 130 grams, size Φ 132X360X1 (wall thickness) * 3 (top thickness), unit is mm, be to utilize the torque equilibrium equation formula to calculate to select well-bucket weight and size, the secondary valve opening Φ of adapted 1.5mm again, main valve hole Φ 6mm, lever ratio 39mm/13.5mm, filling the vapour height in the moment equilibrium state well-bucket under Maximum differential pressure 19.0MPaG is 149mm, filling the vapour height in the moment equilibrium state well-bucket under Minimum differntial pressure 0.05MPaG is 174mm, filling vapour height allowance is 182mm, can guarantee drain valve switch motion normal reliable in 0.05～19.0MPaG operating pressure differential scope.Uncovered downward float (being well-bucket 5) is the dynamical element of this Automatic steam trap Trap, long, the heavier well-bucket of employing cooperates than the big lever ratio with than the opening force of big piston area ratio with the increase valve, satisfies the high technology parameter request of high temperature, high-pressure large-displacement Automatic steam trap Trap.
