Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and 2, a kind of hydraulic dynamic three-way stop valve comprises valve body 1, is located at the spool 2 in the valve body, drives valve rod 3 and valve rod driving structure that spool opens and closes.The and arranged on left and right sides of valve body is shaped on left passage 1-1 and right passage 1-2 respectively; The middle part of valve body is shaped on the central passage 1-3 with above-mentioned two channel connections; Concrete, in the time of in being installed in the cold water group system that steel pipe quenches, central passage is connected with water inlet; Left side passage or right passage are connected opposite side passage and backwater channel structure with quenching with water channel.The upper/lower terminal of said valve body is separately installed with bonnet 4 and bottom flange 5, the middle part of said upper and lower valve gap be welded respectively first guide sleeve 6 and second guide sleeve 7.Said valve rod is installed in first guide sleeve; Be provided with sealing configuration between first guide sleeve and the valve rod; The sealing structure can constitute by being located at multiple-sealed ring between the two; Consider that from the angle being convenient to process and keep in repair above-mentioned sealing configuration also can be made up of the gland 8-2 and the gland 8-3 that are filled between the two sealing material 8-1, from bottom to top are pressed on sealing material top, gland is connected through the upper end of the fastening piece and first guide sleeve; For making the tightr of sealing material compacting, can in the sealing material, be provided with spacer 8-4.The both sides of the inherent central passage of said valve body are provided with valve port 1-4 and lower valve port 1-5.Said spool is made up of last flap 2-2 and the lower Disc 2-3 that poppet shaft 2-1 and backstep welding are contained on the poppet shaft; For guaranteeing that spool is installed in the valve body; At least one flap will be made two style structure in the two above-mentioned flaps; Promptly by be welded on poppet shaft the flap main body and constitute through the connected flap of fastening piece lid, this structure is embodied on the flap in the drawings, the flap lid should be flap mutually and covers 2-2-1.The upper end of said poppet shaft is connected with the lower end of valve rod is coaxial; Concrete, can near the position of upper end tapped hole be set in poppet shaft, the end portion of valve rod is processed into the screw portion that cooperates with tapped hole; Radially process pin-and-hole at screw rod and screw corresponding position; Through screw portion is screwed in the screw, plug-in mounting upper pin 9 in pin-and-hole can be realized being connected of poppet shaft and valve rod then.The end portion of above-mentioned poppet shaft is inserted in second guide sleeve.The said flap of going up is pressed on the valve port place when valve rod moves down, lower Disc is pressed on the lower valve port place when on valve rod, moving.Above-mentioned valve rod driving structure comprises the oil cylinder 10 that is connected with the valve rod upper end, and said oil cylinder is installed in the top of first guide sleeve through support 11.
Said structure drives spool at oil cylinder effect lower valve rod and moves up and down, speed and pressure when contacting with valve port for ease of the control flap; Reduce the impact of flap to valve port, the utility model also comprises the positioning device of the upper and lower motion of valve rod, and said positioning device is by the pointer 12 that vertically is packed on the valve rod; With the sensing plate 13 that an end of pointer is connected, the upper end induction switch 14 that is installed in support one side is with lower end induction switch 15 and be installed in the support opposite side and scale 16 formations that pointer aligns, and is concrete; Upper end induction switch and lower end induction switch constitute by two induction switches that are close to up and down; When valve rod drive sensing plate moved to the inner switch position of two ends induction switch, to control system, the delivery rate of oil pipe slowed down to corresponding induction switch in system with signal feed back; And then the travelling speed of reduction valve rod; When sensing plate moved to the outer switch position, to control system, system stopped to the oil cylinder fuel feeding corresponding induction switch with signal feed back; Make the valve rod stop motion, this moment, wherein a flap was pressed on the corresponding valve port.
The operating mode of above-mentioned hydraulic dynamic three-way stop valve is: valve rod drives frequent the moving up and down of spool; Upper and lower flap alternately is pressed on the corresponding valve port; Impact resistance when contacting with valve port for improving flap; And then the working life of improving spool, the shock-resistant ring 17 that can be respectively on upper and lower valve port and corresponding flap position contacting are welded, be made, hard alloy layer 18 on the corresponding site of upper and lower flap is welded by Hardmetal materials; Concrete, above-mentioned shock-resistant boxing is contained on the lower port seat of upper end-hole position and lower valve port of valve port.
Above-mentioned spool is compared with universal cutoff valves with the cooperating structure of valve port; Slowed down valve opening with close in the closed procedure current to the impact and the water hammering of valve inner passage; Said upward flap and lower Disc can further adopt circular cone bench-type structure; In addition, for reducing the flow resistance of water in valve channel, above-mentioned left passage and right passage all adopt at the turning and seamlessly transit arc structure.
Above-mentioned first guide sleeve and second guide sleeve have been guaranteed spool vertical motion up and down; But because valve rod all adopts disc to cooperate with first guide sleeve and poppet shaft with second guide sleeve; Under the effect of water flow inside; Spool possibly rotate, and causes flap and valve port to wear and tear in the contact position, reduces sealing.For avoiding spool to rotate; Keyway 2-1-1 can be set on the end portion of poppet shaft; In second guide sleeve, install flat key 19, through flat key being inserted the rotation of eliminating poppet shaft in the keyway, and then guarantee that flap is in the static seal state when contacting with valve port.
Above-mentioned threeway liquid operated globe valve in working order down; The valve rod and first guide sleeve and poppet shaft and second guide sleeve are in frequent kinetic friction state; First guide sleeve and second guide sleeve can be respectively by the whole machine shapings of high-abrasive material; Consider that with the angle of being convenient to maintain and replace first guide sleeve and second guide sleeve preferably adopt the plain carbon steel material from reducing fabricating cost, overlap 20 in two guide sleeves, all forming by the high-abrasive material manufacturing on the setting-in.In working order down, valve rod and poppet shaft all with the direct contact friction of interior cover, one side guarantees the vertical motion in valve body of valve rod and poppet shaft to have reduced manufacturing and maintenance cost on the other hand.
In valve class technical field, position that cooperates with valve gap on the valve body and valve gap adopt round structure usually, and for ease of installing and improving the soundness that valve body is connected with valve gap, the position that contacts with valve gap on above-mentioned upper and lower valve gap and the valve body all is preferably square structure.
To sum up, the utility model adopts said structure, and the effect through oil cylinder drives spool and moves up and down; Upper and lower valve port on the valve body is is alternately opened and closed; Satisfied the working condition requirement of steel pipe's production, in addition, the flap opening-closing process is identical with of the prior art two logical stop valves; The face that is moment separates and contact, so has higher serviceability.
