Abstract
The utility model discloses a there is not multi-functional valve of cutting of leakage for to fluid line is by or flow control, including valve body, valve gap, valve rod and valve clack, the valve rod upper end is equipped with the hand wheel, is equipped with sealed pressure cover in the valve gap, its and valve rod surface movable seal cooperation, the surface is equipped with protruding edge in the valve rod, the up end of protruding edge and the sealed lower terminal surface seal cooperation that presses the cover, the fixed connecting pipe that is equipped with on the valve clack, threaded connection under connecting pipe inner wall and the valve rod, still be equipped with the spout cover outside the valve rod, be equipped with the spout on its inner wall, it arranges the spout in to be equipped with the slider on the connecting pipe and cooperates, spout cover lower extreme and the oblique upper end of valve clack constitute. The utility model discloses make the last sealed reliable, effectual of valve, avoided with the problem that the easy wearing and tearing of filler top seal leaked, the maintenance work load of the valve that significantly reduces, and the utility model discloses it is light fast to open and close.
Description
Technical field: the utility model relates to a kind of valve, and particularly the convection cell pipeline blocks and the multi-functional stop valve of Flow-rate adjustment.
Background technique: existing various valves all adopt packing seal to the last sealing of valve rod and valve gap, and valve rod is very big to the filler wearing and tearing in lifting opens and closes, and is easy to make on the medium and leaks, and frequently change filler and then quite bother, the increase expense, it is unobstructed to influence pipeline.And existing valve, the more particularly valve of big latus rectum, keying moment is bigger, and valve rod travel is long, makes the valve opening and closing time long, opens and closes effort.
Summary of the invention: the utility model is that sealing effect is poor on the existing valve of solution, goes up the problem of leaking easily.The utility model comprises valve body, valve gap, valve rod and flap, valve rod upper end is provided with handwheel, is provided with sealed pressing sleeve valve rod outside, in the valve gap, itself and stem exterior surface motive sealing cooperation, the surface is provided with the convex edge in the valve rod, and the upper-end surface of convex edge and the lower end surface of sealed pressing sleeve are sealed and matched; Be fixed with connecting tube on the flap, connecting tube inwall and valve rod lower end are threaded, and also are provided with the chute cover in valve body, outside the valve rod, and its inwall is provided with chute, and connecting tube is provided with slide block and places chute to cooperate; The oblique upper end formation of chute cover lower end and flap is sealed and matched, and the valve base sealing in the oblique lower end of flap and the valve body cooperates.
The utility model valve rod in the switching process need not move up and down, and the flap lower end seals up behind the valve seat by the effect of being threaded of connecting tube and valve rod during full cut-off, and valve rod is slightly upwards carried, and the convex edge of valve rod and sealed pressing sleeve lower end cooperate goes up sealing.Sealing is gone up in the lower end cooperation of flap and chute cover during standard-sized sheet.Sealed pressing sleeve and stem exterior surface are motive sealing, also can keep sealing at standard-sized sheet in the full cut-off process.Of the present utility model upward sealing effect is very good, can not leak, and need not use filler, can not wear and tear, and reduces valve and safeguards.
The utility model can use multiple thread to connect valve rod and connecting tube and flap, and the valve rod slow-speed can make the flap fast moving like this, significantly reduces opening and closing time.
The utility model can also be with hole in the sealing of valve body as the medium import, and pressure medium and flap movement direction reduce and close moment in the same way when closing like this, closes lightly, can end fast.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is embodiment's main structure schematic representation.
Embodiment: as shown in the figure, valve gap 2 is positioned on the valve body 1, and valve rod 3 is placed in one, and valve rod 3 upper ends also are provided with handwheel 4.Be provided with sealed pressing sleeve 6 outside valve rod 3, in the valve gap 2, itself and valve rod 3 outer surface motive sealings cooperate, and the surface is provided with convex edge 5 in the valve rod 3, and the lower end surface of the upper-end surface of convex edge 5 and sealed pressing sleeve 6 is sealed and matched; Be fixed with connecting tube 8 on the flap 7, connecting tube 8 inwalls and valve rod 3 lower ends are threaded, and also are provided with chute cover 9 in valve body 1, outside the valve rod 3, and its inwall is provided with chute 10, and the slide block 11 that is provided with of connecting tube 8 places chute 10 to cooperate; The oblique upper end formation that chute overlaps 9 lower ends and flap 7 is sealed and matched, and the valve base sealing in the oblique lower end of flap 7 and the valve body 1 cooperates.Generally be provided with O type circle between sealed pressing sleeve 6 and the valve rod 3 and strengthen motive sealing, connecting tube 8 and flap 7 can be made integral type, and the cooperation by slide block 11 and chute 10 during keying moves up and down connecting tube 8 and flap 7.Connecting tube 8 and valve rod 3 can be used multiple thread, generally connect with triple thread to make flap 7 fast moving.Present embodiment with hole 19 in the sealing in the valve body 1 as the medium import, under the sealing of opposite side the hole as media outlet, opposite with general valve, can reduce like this by the time close moment, end fast.
Present embodiment can also be regulated flow, make flap 7 be in semi-open state exactly, it is reliable for going up of this moment sealed, adjusting sleeve pipe 12 has been threaded on valve gap 2 tops, valve rod 3 tops are placed in one and are rotatably assorted, also be provided with bearing 14 and nut 15 on the valve rod 3 of adjusting sleeve pipe 12 tops, handwheel below, nut 15 and valve rod 3 are threaded, and regulate also to be connected with on the sleeve pipe 12 on the degree of tightness handle 13 formation valve rods 3 and carry mechanism.So only need to rotate degree of tightness handle 13, valve rod 3 is carried on slightly, the convex edge 5 of valve rod 3 and sealed pressing sleeve 6 are cooperated go up sealing, avoid the wearing and tearing and the last leakage that only may have with sealed pressing sleeve 6 and valve rod 3 motive sealings.When changing flow, unclamp earlier degree of tightness handle 13 again adjusting handle 4 flap 7 is moved.Be provided with vertical groove at valve gap 2 sidewalls, groove is provided with scale 16, the land 17 that has been threaded on the valve rod 3 in the valve gap 2, and indicating arm 18 1 ends of level are connected on the land 17, and the other end places groove and scale 16 to cooperate the formation flow indicator means.Valve rod 3 rotates land 17 is moved together with indicating arm 18 when regulating, but by contrasting accurate flow adjustment with scale 16.Present embodiment is regulated with handwheel 4, in fact use pneumatic or Electric actuator can.
