Embodiment
Be described in detail with reference to the attached drawings a embodiment according to gate-valve device of the present invention.Fig. 1 shows the state that inserts before the gate valve element,, is connected to existing pipe according to the gate-valve device of present embodiment that is, and Figure 1A shows vertical sectional structure of axially looking along pipe, and Figure 1B shows the horizontal sectional structure with the pipe parallel to an axis.In Fig. 1, existing pipe is shown by dashed lines.
Described gate-valve device A is connected to existing water pipe K, and is made up of lower shell piece 1, middle shell spare 2 and upper shell spare 3.Independently housing member 1,2 and 3 fixed mechanisms 4 that constitute by screw bolt and nut interfix for these.Encapsulation is inserted between each housing 1,2 and 3, so that form watertight construction.
In each housing member 1,2 and 3 inside, settle the gate valve element (hereinafter referred to as the valve element) 5 shown in Fig. 2 A and 2B.In described valve element 5, the internal surface of its lower end contacts with the lower end 10c of valve rod 10, and valve rod 10 is lifting axiss, and the rotation of valve rod 10 and descending motion move down valve element 5, that is, insert among the water pipe K.The upper end 10a of valve rod 10 can manually or automatically rotate by the rotary jig (not shown).When valve rod 10 rotation, the screw element 11 at the central upper place by being connected valve element 5 and be formed on the effect of being threaded between the outside thread 10b in the valve rod 10, valve element 5 can vertically move.
In addition, Fig. 2 A shows half vertical sectional structure of valve element, and Fig. 2 B shows half horizontal sectional structure of valve element.Thereafter, described valve element 5 will be described.
Described valve element 5 is made of valve element core metal accessory 6 and rubber lining 7, and described rubber lining 7 is elastomer seals and covers the part that valve element core metal accessory 6 contacts with the water of tube interior.In other words, it is configured to: rubber lining 7 covers valve element core metal accessory 6 downwards from the flange portion 6a of valve element core metal accessory 6, and flange portion 6a is circumferentially outstanding along the peripheral shape of pipe.Described rubber lining 7 also has flange portion 7a, and described flange portion 7a is circumferentially outstanding and can block the boring opening 8 that forms through hole when valve element 5 inserts in the pipe.The flange portion 6a of valve element core metal accessory 6 has the upwards effect of distortion of flange portion 7a that prevents, in order to avoid contact with pipe K and described rubber lined flange portion 7a distortion and dashing forward to upside during pressurized.
In the tip part of rubber lining 7, form protruding part 7b, described protruding part 7b has partly the external shape in week in the bottom of inside tube.Particularly, described protruding part 7b be used to rubber lining 7 move through pipe and with pressurized and distortion continuously after the bottom of inside tube contacts, with the increase power that blocks water.Like this, because the setting of protruding part 7B, the decrement of rubber lining 7 is bigger in the part when pressurized, make to obtain to block water reliably with little moment of torsion, and structure can reduce the moment of torsion of down periods.
Shown in Fig. 2 B, because rubber lining 7 is formed with thickness portion L1 and thin partial L 2 at the bit point that constitutes protruding part 7b, so it can handle the pipe that each has same outer diameter as, different inner diameters neatly, so that stop water reliably.Thus, with respect to being arranged on not the pipe of same date and pipe, can implement high block-water performance with different internal states.In this case, constitute protruding part 7b thin partial L 2 width preferably thickness portion L1 20% to 60%, more preferably be 30% to 50%.
Valve element core metal accessory 6, from the bottom of flange portion 6a, described valve element core metal accessory 6 has tapering part and the guide edge part 6c in side surface 6b, described guide edge part 6c is guide edge part and its most advanced and sophisticated attenuation, shown in Fig. 2 A.The tiltangle of tapered side surface 6b is preferably 20 to 30 degree.In this scope, when rubber lining 7 inserts in the pipe, and the protruding part 7b of rubber lining 7 contacts with the bottom of inside tube and during pressurized, for along continuous straight runs disperses compressive force simultaneously, even less power also can be implemented to disperse, and the moment of torsion when valve rod moves through pipe is little, can obtain high block-water performance.In having the guide edge part 6c at attenuation tip, chamfered portion 6d is formed on the inboard, and when rubber lining 7 is compressed and deforms, the existence of described guide edge part 6c can prevent rubber lining 7 reliably along the direction projection parallel with the tube axis of tube interior, thereby rubber lining 7 can closely contact inner surface of tube effectively.
Then, with reference to figure 3 to 5, describe gate-valve device A and be connected to existing water pipe K to stop the process of water.
At first, after gate-valve device A was connected to pipe K, 92 to 100% the hole saw 12 that external diameter is equivalent to pipe K internal diameter was used to pipe K is holed, and rotates hole saw 12 simultaneously.In this case,, can in the internal surface of pipe, produce step after cutting is finally finished, may destroy the performance that blocks water like this when the external diameter of hole saw 12 during greater than the internal diameter of pipe K.When the external diameter of hole saw 12 less than the internal diameter of pipe K 92% the time, just need rubber lining when utilizing valve element 5 to stop water, very big distortion to take place, thereby make the block-water performance instability.
When utilizing hole saw 12 to finish when boring, hole saw 12 is pulled up, and the valve element is lowered in the pipe, and the upper end 10a by rotary valve rod comes rotary valve rod 10 simultaneously.Fig. 4 shows at will descend state before entering pipe of valve element 5, and Fig. 4 B is a transverse sectional view.In Fig. 4 to 6, only show valve element 5 and pipe K in order to simplify.
In Fig. 4, almost the bore diameter L4 with pipe K is identical for the width L3 that locates in the bottom of valve element 5 (having used rubber lined part).
When valve element 5 arrives the lower surface of pipe K inboard, obtain state as shown in Figure 5.In this stage, the rubber lining that is positioned at valve component side surface does not contact with tube wall, and it is not in the state that can stop water like this.Thus, the flow through water of pipe flows through gap, arrival downstream side between the side surface of boring opening 8 and valve element 5.
When valve rod 10 is further rotated and fixedly the time, valve element 5 descends, and as shown in Figure 6, in the bottom of the protruding part 7b of rubber lined bit point pressurized, to realize the pressure contact and to be compressed distortion to pipe.Simultaneously, it contacts with the side surface of inside tube, to obtain closely contact and to block tube interior.In this, tube interior can be blocked reliably, and water can be prevented from.Thus, can freely implement various engineer operations in the downstream.
