Technical field
The utility model relates to the valve body field, and specifically, the utility model relates to a kind of import and export at the duplex tee ball valve that is used for duplex strainer of heteropleural.
Background technique
Duplex strainer: the online pipeline that is mainly used in lubricant oil, hydraulic oil, turbine oil filters.Its main structure is to utilize the duplex tee ball valve that two filters are connected, wherein filter work when operation, and another is standby.Filter under in running order reaches when changing the requiring of filter element, and utilizes the duplex tee ball valve to switch, and makes original standby filter enter working state.After switching is finished, another filter is carried out the replacing of filter element, enter stand-by state then, circulate with this.The great advantage of duplex strainer is exactly the on-line continuous operation that can guarantee system, avoids taking place when changing filter element the cutout phenomenon.
Fig. 1 crosses the plan view of elimination for the duplex that prior art is equipped with the duplex tee ball valve; Fig. 2 is the plan view of Fig. 1; From Fig. 1, Fig. 2 as can be seen, the import and export of duplex strainer A1, A2 are at heteropleural, and two cartridge filters of A1, A2 the using and the reserved on pipeline connect by duplex tee ball valve A5.
The structure of duplex tee ball valve A5 mainly comprises upper valve body 1, following valve body 2 shown in Fig. 3 a, Fig. 3 b, spool is spheric structure, and driving mechanism is turbine worm structure A4, and the rotation by handwheel A3 comes rotational valve core.Duplex tee ball valve A5 has six through holes, and wherein four through holes link to each other with two filters, are the oil inlet and outlet of two filters.Two through holes link to each other with system in addition, are the oil inlet and outlet of whole duplex strainer.
In the running, when A1 needed to change the filter core of the inside after operation a period of time, will switch this moment by duplex tee ball valve A5, and A2 is brought into operation, and switches the back that finishes A1 is carried out the replacing of filter core.Find can have about 1 minute cutout phenomenon in the process that tee ball valve A5 switches but be in operation, there is certain problem in main cause with regard to the spool design that is duplex tee ball valve A5, and this is breakneck for whole system.
The working principle of existing duplex tee ball valve is described below:
By Fig. 3 a, 3b as can be seen, original duplex tee ball valve is divided into upper valve body 1, following valve body 2, and is middle by the connection of turbine worm driving mechanism.Spool 10, spool 20 structures of upper valve body 1, following valve body 2 are " T type " structure, and upper valve body 1, following valve body 2 are in the same way and rotate when rotated.When the state 1 of being in, the import of A2 filter and outlet all are open mode, proper functioning.And the inlet/outlet of A1 filter all is closed condition, is in stand-by state.When moving the filter core that needs to change after a period of time among the A2, rotate the handwheel A3 on the valve body this moment, handwheel A3 drives spool 10, spool 20 rotations by the turbine worm structure.Behind half-twist, be in state 2, by Fig. 3 c, 3d as can be seen, after following valve body 2 rotates counterclockwise, import and export and also to be in connected state, but upper valve body 1 to be after half-twist, sphere just in time blocks system's master's filler opening, and causing can't oil-feed.Just in the process of switching, duplex strainer master filler opening is little by little closed, and cutout appears in complete choke-out during to 90 °.But revolve again turn 90 degrees after, be behind the Rotate 180 °, during the state 3 of reaching, by Fig. 3 e, Fig. 3 f as can be seen, the master of duplex strainer all is in connected state into and out of hydraulic fluid port, and the inlet/outlet of A2 filter is then sealed by sphere, is in stand-by state, at this moment, can carry out more renew cartridge operation to the A2 filter.And the A1 filter is all opened into and out of hydraulic fluid port, in running order.Equally, after the A1 filter reruns a period of time, when needing more renew cartridge, also be by rotating handwheel A3, clockwise rotating spool 10, spool 20.In the process, the blocked phenomenon of duplex strainer import can appear equally since then.
Can find clearly that from the work schematic representation of existing duplex tee ball valve there is following problem in the existing duplex strainer of importing and exporting at the heteropleural duplex tee ball valve of carrying out task switching that is in operation:
1, its upper and lower spool is " T type " structure, and turns to identically, causes in handoff procedure, when ball valve began to switch, the import of duplex strainer was little by little stopped up by the sphere of upper valve core, when ball valve switches to 90 °, import is blocked fully, causes system cutout to occur; When rotating to 180 °, switch and just formally finish.In this process, changing is appearring in flow always, even cutout occurs, is having a strong impact on the security of operation of main process equipment;
2, existing duplex tee ball valve needs Rotate 180 ° just can finish the switching of filter cylinder, and effort during operation, and the operating time is longer.
At the prior art above shortcomings, the utility model is proposed.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Fig. 4 a is the structural representation of duplex tee ball valve of the present utility model; Fig. 4 b is that the B of Fig. 4 a is to view; Fig. 5 a is the structural representation of the upper valve body of duplex tee ball valve of the present utility model when being in state 1; Fig. 5 b is the structural representation of the following valve body of duplex tee ball valve of the present utility model when being in state 1; With reference to Fig. 4 a, Fig. 4 b, Fig. 5 a, Fig. 5 b, duplex tee ball valve of the present utility model comprises upper valve body 1 and following valve body 2, and upper valve core 10 is arranged in the upper valve body 1, in the following valve body 2 lower valve core 20 is arranged, and upper valve core 10 is spheric structure with lower valve core 20; Upper valve body 1 is connected with worm-and-wheel gear A4 with following valve body 2, on the worm and gear structure A4 gear box A 6 is installed, promote upper valve core 10 by worm and gear structure A4 and gear box A 6 and be the opposite direction rotation with respect to lower valve core 20, upper valve core 10 and lower valve core 20 internal channel structures are the ┓ type, and upper valve core 10 is with respect to lower valve core 20 half-twist settings.
At the duplex strainer problem of importing and exporting at heteropleural that the duplex tee ball valve occurs when switching, former duplex tee ball valve is improved, be mainly reflected in following some:
1, the agent structure of former duplex tee ball valve is constant, but changes spool design, changes upper and lower spool into " ┓ type " structure by original " T type " structure;
2, the upper and lower spool of former duplex tee ball valve is when rotating, and turns to identically, after the improvement, makes upper and lower spool direction when rotating opposite;
3, " T type " structure ball valve is when rotating by handwheel, and upper and lower spool needs Rotate 180 °; And " T type " structure when rotated, and upper and lower spool only needs half-twist.
Describe structure of the present utility model and working procedure in detail below in conjunction with accompanying drawing 5a-Fig. 5 j:
At first from spool, originally upper and lower spool all is " T type " structures, changes " ┓ type " structure now into, and briefly namely former " T type " is to have opened three outlets at sphere, change " ┓ type " structure now into after, have only two outlets at sphere.
Secondly, on the direction when switching variation has taken place also, namely direction is opposite when rotated for upper and lower valve body, and this point is to install gear box A 6 structures additional by the basis at former " T type " ball valve drive structure of gear worm A4 to realize.
Operate to example earlier with the A2 filter in the initial state duplex strainer, shown in the state 1 among Fig. 5 a, upper valve core 10, the lower valve core 20 of " ┓ type " structure makes the import and export of duplex strainer all be in whole open modes, filter A2 proper functioning, and all being blocked by the sphere of upper and lower spool into and out of hydraulic fluid port of another filter A1 is in stand-by state.
After operation a period of time, the A2 filter needs more renew cartridge, need switch to the operation of A1 filter.Begin to rotate the handwheel A3 of duplex tee ball valve this moment, by worm and gear structure A4 and gearbox drive device A6, and rotation upper valve core 10, lower valve core 20.Upper valve core 10 clockwise rotates, and lower valve core 20 rotates counterclockwise.For this process of more careful description, we will choose the several points of upper and lower spool in rotary course and describe.
Being example with the state 2 among Fig. 5 c, Fig. 5 d, is by after rotating handwheel A3, upper valve core 10, phase diagram when lower valve core 20 begins to rotate 30 °.From the figure as can be seen, upper valve core 10 clockwise rotates 30 degree, the import of duplex strainer at this moment still is in open mode, and (middle shade is two supports between the spherical opening, do not influence flow, can ignore), and the import of filter A2 reduces gradually, and the import of filter A1 is opened.After lower valve core 20 rotates counterclockwise 30 °, compare with reset condition, the outlet of its A2 filter is being closed gradually, and the outlet aperture of A1 filter is then becoming big.Generally speaking, be exactly behind 30 ° of upper valve cores 10, lower valve core 20 each spinning, this moment, duplex strainer was to be in two filters of A1, A2 working state simultaneously, the overall process oil mass does not change.
Be example with the state 3 among Fig. 5 e, Fig. 5 f, upper valve core 10, lower valve core 20 are after 45 ° of each spinnings under the transmission device effect, the aperture of upper valve core 10, lower valve core 20 all mediates at this moment, that is to say, flow by A1, A2 filter is identical at this moment, but total oil mass does not change, and any blockage problem does not take place yet in the import and export of duplex strainer.
Be example with the state 4 among Fig. 5 g, Fig. 5 h, upper valve core 10, lower valve core 20 are after 60 ° of each spinnings under the transmission device effect, this moment, the import and export of duplex strainer still were in whole open modes, and on internal distribution, the import and export aperture of filter A1 just is greater than the import and export aperture of filter A2, that is to say that the task amount of filter A1 this moment is greater than filter A2.
Be example with the state 5 among Fig. 5 i, Fig. 5 j, upper valve core 10, lower valve core 20 are behind half-twist, this moment filter A2 into and out of the hydraulic fluid port Close All, and all the opening into and out of hydraulic fluid port of filter A1, duplex strainer still be whole open modes into and out of hydraulic fluid port, duplex strainer is finished handover operation.Next can carry out corresponding filter core to the A2 filter more changes jobs.
Equally, after a period of time of reruning, when filter A1 needs more renew cartridge, be exactly the contrary operation of above-mentioned action, i.e. opposite spin handwheel A3, upper valve core 10 counterclockwise rotates, and lower valve core 20 clockwise rotates.
In a word, behind the valve core structure and sense of rotation that change the duplex tee ball valve, duplex strainer is in handoff procedure, and the cutout phenomenon does not all take place inlet/outlet, and system is not affected, and has well solved the problem that former duplex tee ball valve exists.
The above embodiment; it is preferred embodiment of the present utility model; be not to limit the utility model practical range; so it is all according to the described apparent change of the utility model claim; and other does not break away from the change of the utility model essence, all should be included within the protection domain of the present utility model.
