Abstract

The utility model relates to a shunt valve, belonging to the valve class. The utility model has a cylindrical valve body and a conical inner chamber, and the body wall is provided with a plurality of rows of radial through holes on the same generatrix. A valve core is cylindrical, and the appearance of the valve core is conical; a plurality of slotted holes are arranged on the same generatrix of the valve core; a valve core cover of a jack head through hole is enclosed in the large end of the valve core. A partition board is arranged in the inner chamber. When a handwheel and a valve rod are turned to generate different angles, the positions of the valve core and the valve body are mutually changed, and a plurality of different paths can be formed; but only one path is opened while other paths are all automatically closed with the opening of the path, or the whole paths are closed. The utility model can be widely used for the chemical industry and the medicine, and can be used for controlling other various liquid pipelines.

Description

Shunt valve

The utility model belongs to valve type.

The switch valve of the chemical reaction jar cooling system that prior art provided adopts several general standard valve usually, and switch switches cooling system and easily causes operate miss, and obscuring of different cooling mediums run off.And single valve seal point is many, easily leaks.

Task of the present utility model provides a kind of multichannel flow divider that has, and good airproof performance can be avoided operate miss, reliable operation fully.

Now with retort cooling system in the chemical and medicine industry production be example as an illustration, the chemical reaction jar often need the cooling, the need that have drop to below the room temperature.Be energy saving, general earlier with about 18 ℃ tap water, or the circulating water about 28 ℃ (abbreviation clear water), cooling, and then change brine ice (10 ℃～-15 ℃) and lower the temperature.Operating process is that first opening or cleaning water advances valve and reflux valve, when treating that clear water can not be lowered the temperature again, the cooling of change brine ice, at this moment clear water be need close and valve and reflux valve advanced, drive compressed air valve and clear water pressure valve again, reflow pipe is arrived in the whole pressures of clear water in the retort interlayer, closes compression air valve and clear water pressure valve then, open brine ice again and advance valve and brine ice reflux valve, wait to drop to temperature required, stop the cooling, close brine ice and advance valve and reflux valve, drive compressed air valve and brine ice pressure valve the brine ice reflow pipe is arrived in the whole pressures of jar interlayer brine ice, carry out next process again.This shows that cyclic process of operation needs 16 valves of switch, easily make jar interlayer cooling medium pressure clean or cause operate miss, advance valve, forget that closing valve just opens brine ice and advance valve, reflux valve as only closing clear water, make a large amount of brine ices enter clear water, cause brine ice to run off in a large number.And for example close brine ice and advance valve, forget the occlusion pressure valve, opening or cleaning water valve and reflux valve, clear water will enter in the brine ice, make brine ice dilution and freeze.Must fill out and join salt.The numerous valves of frequent operation are easy to misoperation, produce the cooling medium string and mix, and cause very large economy loss.

The technical characterstic of this diverter valve is, offers the radial through holes of many rows on the valve body, and spool hollow is also axially separated multicell, only offers the corresponding long-round-shape hole of a plurality of and radial through hole in relevant position, same axial cross section the same side.Spool and valve body cooperate for the cone facing-up.Spool rotates relative to valve body, and the through hole at valve body two ends can constitute different passages with radial hole on the diverse location on the valve body through valve core chamber.

Below in conjunction with a description of drawings most preferred embodiment of the present utility model.

Fig. 1 diverter valve structural representation;

Fig. 2 diverter valve I-I sectional drawing;

Fig. 3 diverter valve II-II sectional drawing

As shown in Figure 1, diverter valve is by handwheel 3, valve rod 8, valve body 15, spool 16, bonnet 7, bottom flange 20 reaches the fixedly nut 1 of handwheel, packing ring 2, the filler 6 of fastening valve rod, Sealing 5, gland 4 and clamping bolt are formed, it is characterized in that, valve body is one cylindric, inner chamber is conical, the flanged dish in two ends, through hole is arranged and take over 9 on the valve body wall outside the spool of big end, through hole on the same bus of many rows is arranged on the body wall of valve core chamber relatively and take over 12,13,22,23,17,18,24,25, spool also is cylindric, appearance is conical, there is dividing plate 14 centre, big termination package center has the spool loam cake 10 of insertion and extraction head through hole, and valve rod one end connects handwheel 3, there is angle fixed point sign in the handwheel outside, and the round angle angle index is arranged on the gland.The valve rod the other end has cross to pull out 11, inserts in the cross bore of spool loam cake, leaves the space between cross outer end and the hole.Between valve body 15 and the bottom flange 20 seal ring 19 is arranged.

With reference to the accompanying drawings its working procedure is illustrated, shown position is filling brine ice path, and brine ice is raised to tank deck → pipe 21 → core chamber → pipe 17 backflows at the bottom of managing 12 → core chamber → cross bore → pipe 9 → retort.Cooling stops, clockwise rotate handwheel 90 degree, spool bore is aimed at 22,24 mouths of pipe, then pressurized air by pipe 24 → core chamber → pipe 21 → retort roof pressure the jar end of to → pipe 9 → cross bore → core chamber → pipe 22 is clean with the brine ice pressure, clockwise rotate handwheel 90 degree again, spool bore is mating holes 13,18 respectively, then links up the clear water road.Cooling water is raised to tank deck → pipe 21 → core chamber → pipe 18 backflows at the bottom of managing 13 → core chamber → cross bore → pipe 9 → retort.When needing to get rid of clear water, clockwise rotate handwheel 90 degree.At the bottom of pressurized air is discharged to jar by pipe 25 → core chamber → pipe 21 → retort roof pressure → and manage 9 → cross bore → core chamber → pipe 23, the clear water pressure is clean.Clockwise rotate handwheel 90 degree again and then turn back to the home position, can begin next programmed sequence of operations.

That this diverter valve has is simple to operate, reduce leak, long service life.After the path that needs was opened, other paths were all closed automatically, not in calibration position, can close whole passages, can avoid the multiple fluid string to mix so fully.

This diverter valve can be widely used in chemical industry, the cooling system of medicine production and the control of multiple fluid pipeline.
