Description
Technical field
The utility model is related to a kind of valve and in particular to a kind of heavy caliber low torque Double-clack stop valve.
Background technology
Because during opening and closing, between sealing surface, frictional force is little, relatively durable, Lift less, manufactures and holds stop valve
Easily, easy to maintenance, it is applicable not only to mesolow, and be applied to high pressure.The closure principle of stop valve is to rely on the axial direction of valve rod
Pressure, makes valve clack sealing surface fit tightly with sealing surface of seat, stops flow of media from bottom to top, but this structure belongs to
Forced seal formula structure, so in valve closing it is necessary to apply pressure to flap, do not leaked with forced seal face.Work as medium
During by entering valve below flap, the resistance overcoming required for operating physical force, is valve rod and the frictional force of filler and the pressure by medium
Thrust produced by power, the power of closing valve is bigger than the power of valve opening door, so the diameter of valve rod is big, valve rod bending otherwise can occur
Fault, during in particular for accomplishing more than dn200 bore, stem diameter need to be very big, and the operational torque closed also needs
Bigger.Because said structure leads to when accomplishing the stop valve of more than dn200 bore the very big stem diameter of needs and very big

Specific embodiment
Below in conjunction with the accompanying drawings the utility model embodiment is described further.
As shown in Figure 1 with Figure 2, a kind of heavy caliber low torque Double-clack stop valve, including valve rod 1, flap 2, handwheel 3,
Water inlet flow channel 6 in valve gap 4, valve body 5 and valve body 5 and outlet passage 7, described valve rod 1 is through in valve gap 4 and described
The lower end of valve rod 1 is stretched in valve body 5 and is connected with flap 2, and the upper end of described valve rod 1 is passed outside valve gap 4 and is connected with handwheel 3,
Described flap 2 is provided with adapter sleeve 8, and described adapter sleeve 8 upper end is provided with limited block 9 and described adapter sleeve 8 and is provided with cunning
Chamber 10, described valve rod 1 bottom is connected with secondary flap 11 and stretches in above-mentioned sliding chamber 10, and described flap 2 is connected with adapter sleeve 8
Place is provided with the liquid inlet 12 communicating with sliding chamber 10, and the described lower curtate flap 2 with sliding chamber 10 coaxial direction is provided with and sliding chamber 10
The liquid outlet 13 communicating, described valve body 5 is fixedly connected with valve gap 4 by bolt, and described valve gap 4 upper end is bolted
It is connected with support 14, described support 14 upper end is provided with groove 15, is provided with valve stem nut 16 and thrust axis in described groove 15
Hold 17.
Preferably, described liquid inlet 12 number is 1 ~ 8, and be isodistantly spaced is radially arranged in adapter sleeve 8 and flap 2
Junction, is provided with reinforcement 18 outside described support 14, is provided with guide rail 19 inside it, and screw is passed through in described valve rod 1 upper end
It is fixed with valve lever clamp 20, described valve lever clamp 20 is slidably connected with guide rail 19.The setting of reinforcement 18 can improve the strong of support 14
Degree, improves the stability of valve body 5, and when opening or to close valve in rotation valve rod 1, valve lever clamp 20 can follows track 19
Do and move back and forth up and down, guide rail 19 can play the effect of spacing guiding.
Preferably, it is provided with sealing ring 21 between described valve gap 4 and valve body 5, sealing ring 21 is used for improving the sealing of valve
Performance；Described adapter sleeve 8 is cylindrical or cuboid, and is coaxially disposed with valve rod 1.
When actually used, valve is arranged on medium pipeline, medium flows to outlet passage 7 from water inlet flow channel 6,
When opening valve, valve stem nut 16 is driven by rotation hand wheel 3 and then carries ovable valve stem 1 slowly to rise, during rising
First drive secondary flap 11 to rise and open liquid inlet 12, at this time medium can flow in sliding chamber 10 from liquid outlet 13 along liquid inlet 12
Flow in outlet passage 7 to reach the pressure balance at sealing pair two ends, thus mitigating the operating physical force that can mitigate valve rod 1 unlatching
Square, when valve rod 1 rises to a certain extent, secondary flap 11 can push up the limited block 9 on adapter sleeve 8, then with adapter sleeve 8
Flap 2 rises, and completes the opening procedure of valve；Close valve when due to medium flow to be by and under (i.e. feed water flow
Road 6 flows to outlet passage 7), make to allow under the active force of medium the operational torque of valve rod 1 do not need just easily to close greatly very much close
Front cover reaches sealing effectiveness, and the help lower sealing surface acting in pressure medium can reach the effect of zero leakage, due to closing
The torsional forces required with the operation opened diminishes, thus reducing the torque pressure of valve rod 1, can reduce the diameter of valve rod 1, and then
Decrease required raw material, cost-effective moreover it is possible to meet the selection requirements to stop valve for the large diameter pipeline.
This heavy caliber low torque Double-clack stop valve good seal performance, disclosure satisfy that the selection requirements of large diameter pipeline, its
Stem diameter is little, material-saving, and valve switch operational torque is less, has with low cost, practical and convenient it is easy to promote etc. excellent
Point.
