The present invention relates to valve, particularly have manual check function, filtering function and regulate adaptation different viscosities media feature automatically, especially have the multi-fork valve of all class functions of solenoid valve, mortor operated valve, pneumatic valve and hydraulic operated valve concurrently.
In the prior art, the valve of band drive unit is a widely used final controlling element in the control automatically.Generally all in its device, increase manually operated valve, filter, safety check or the like bypass accessory and pipeline, not only take up space but also increase expense.Moreover the medium of different viscosities requires different to the technical parameter of solenoid valve, mortor operated valve, pneumatic valve and hydraulic operated valve.General way is solenoid valve, mortor operated valve, pneumatic valve and the hydraulic operated valve by the various different parameters of medium designs of different viscosities now.And the valve that is used for gas can not be used for liquid; Equally, the valve that is used for liquid can not be used for gas.
For addressing this problem, the multi-function electromagnetic valve of the patent No. (85201792) has solved some problems to a certain extent.Though but have adjustable enlargement discharge and close the function of small flow, both can not same usefulness, does not more have the indication and the check function of Flow-rate adjustment.In addition, in order to adapt to the medium of different viscosities, the way that adopts adjusting screw to regulate still still is difficult to adapt to when valve is used on the steam line.Because of accumulating certain condensed water morning in the steam line, if the unsaturated steam in morning is regulated with adjusting screw, noon, major part is a saturated vapour in the pipeline, at this moment valve often is difficult to open; If the unsaturated steam at noon is regulated, during to second day morning, also often can not go to close by the signal of controller instruction or treat that condensed water is discharged and just close after a certain amount of, it be unreliable to cause moving, particularly, just inapplicable by the pipeline of two or more media.
The objective of the invention is to synthetically solve above-mentioned a series of problems, propose a kind of multi-fork valve.
The present invention finishes as follows: the valve that drive unit is generally arranged, by the pilot valve of guiding main valve keying and this two most composition of main valve of control media break-make, there is the duct to be connected between pilot valve and main valve chamber, duct equalizing orifice often between the main back of the body chamber, the gap will be designed to different parameters and the adjusting screw hole, and armrest is moving to be regulated.Change the passage that comes valve body import and spool back of the body chamber to be tightly connected by armature motion in the drive unit now into, open the passage that spool back of the body chamber and valve outlet are tightly connected simultaneously, the medium in back of the body chamber is discharged to valve outlet, make the very fast formation pressure reduction of pressure in main back of the body chamber, and spool is opened; When driving device controls armature is opened the passage that valve body import and spool back of the body chamber is tightly connected, close the passage that spool back of the body chamber and valve outlet are tightly connected simultaneously, the medium chamber of supporting or opposing is soon replenished, main back of the body chamber pressure reaches balance very soon, and spool cuts off the circulation of medium pressing main valve seat under the effect of gravity or spring force.
Pipeline contact formula or contact directly on passage and the static iron core on the valve body of formula and have channel seal to be connected perhaps is connected with the channel seal of processing on the base, or is connected with the channel seal of processing on the valve gap.
The inlet passage of valve body and the passage that back of the body chamber is tightly connected are carried on the back the passage that the chamber is connected with the exit seal of valve body, and its keying is controlled simultaneously by the armature in the drive unit.
Between gland and the fine setting screw rod by the adjustable sealing of adjusting nut or directly seal with seal ring.On the fine setting screw rod non-return mechanism is installed, this mechanism is sealed and matched by non-return core and auxiliary-seat, and crack screw rod is connected by the center trace of fine setting screw rod, non-return core and them.Between non-return core and fine setting screw rod, there is link to flexibly connect.Non-return mechanism fixedly be to be fixedly connected by gland and valve body, the fine setting screw rod be threaded with gland.
The present invention has following advantage than conventional art: automatic, manual two covering devices do not disturb mutually, compact structure, multi-purpose valve, flexible to operation, can regulate medium that adapts to different viscosities and the break-make of controlling a multiple medium of pipeline automatically, and improve the reliability of action widely, and save several manually operated valves, filter, safety check and bypass duct.
Describe in further detail below with reference to accompanying drawing.
Fig. 1 is a pipeline contact formula multi-fork valve structure sectional view.
Fig. 2 is a pipeline contact formula multi-fork valve partial sectional view.
Fig. 3 is the another kind of partial view of pipeline contact formula multi-fork valve.
Fig. 4 contacts directly formula multi-fork valve partial sectional view.
With reference to Fig. 1, drive unit (1) can be electromagnetic coil driving or Electric actuator or Pneumatic actuator or Hydraulic actuator.Between the pilot valve that the guiding main valve opens and closes and the main valve of control media break-make, drive armature (2) action, realize control by drive unit (1).There is the duct to be connected between pilot valve and main valve chamber.
Pipeline is got in touch formula or is contacted directly formula, passage (ob) sealing on passage (oa) on its valve body (7) and the static iron core (23) of pilot valve is connected, perhaps the passage (oa) on the valve body (7) is connected with the channel seal of the last processing of base (22), or is connected with the channel seal of the last processing of valve gap (3); That is to say that the inlet passage (oa) of valve body (7) and the passage that back of the body chamber is tightly connected are carried on the back the passage that the chamber is connected with the exit seal of valve body (7), its keying is controlled simultaneously by the armature (2) in the drive unit (1).
In order to realize Flow-rate adjustment and check function, gland (8) is sealedly and fixedly connected with valve body (7), and fine setting screw rod (10) passes gland (8) center hole, gland (8) with finely tune between the screw rod (10) by adjustable being tightly connected of adjusting nut (9).On fine setting screw rod (10), non-return mechanism is installed, be sealed and matched by non-return core (18) and auxiliary-seat, crack screw rod (11) is connected them by the central duct of fine setting screw rod (10), non-return core (18), between non-return core (18) and fine setting screw rod (10), there is link (17) to flexibly connect, also has check spring (16) between non-return core (18) and the fine setting screw rod (10), or when handwheel (12) position during for direction up, check spring (16) can be cancelled, by closing from gravity of non-return core (18).Whole non-return mechanism is fixedly connected by gland (8) and valve body (7), and fine setting screw rod (10) is threaded with gland (8).
In order to be clear that the flow situation, the scale indication of expression flow size to be arranged on fine setting screw rod (10) and crack screw rod (11), and be useful on the square toes or the handwheel (12) of manipulation.
To regulate with non-return mechanism and can prevent the pollution of the environment in order to make, have a cover cap that the stretch out part, adjusting nut (9), gland (8) of handwheel (12), crack screw rod (11) and fine setting screw rod (10) are sealed and cover in valve body (7) bottom.
Operating principle is as follows: when electromagnetic coil is that drive unit (1) moves then that armature (2) moves upward.(ob) passage on valve body (7) inlet passage (oa) and the pilot valve static iron core (23), open pilot valve passage (od) and valve body (7) outlet passage (oe) simultaneously, medium enters main chamber from the import of valve body (7) filter screen (5) of flowing through, a part of valve body (7) inlet passage (oa) that flows into, static iron core (23) passage (ob) that flows into pilot valve is then closed by armature (2).Another partly enters back of the body chamber from spool (4) external series gap trace and is replenished, because the sectional area of spool (4) external series gap is equal to or less than passage (od) that passage (oc) and spool carry on the back chamber and valve outlet (oe), the very fast minimizing of pressure in back of the body chamber, when it reaches a certain numerical value with the difference of main chamber pressure, spool (4) is subjected to power that medium imposes on greater than the power of spring (20) with from gravity, make spool (4) leave seat of honour valve, the moving check spring (16) of trying hard to recommend that medium imposes on non-return core (18) makes valve opening.When electromagnetic coil is that the armature (2) of drive unit (1) control pilot valve moves downward, open static iron core (23) passage (ob) of valve body (7) inlet passage (oa) and pilot valve, close the passage (oe) of pilot valve passage (od) and valve body (7) outlet simultaneously, a part of medium is promptly from above-mentioned passage flow channel (ob), then flowing into armature (2) external series gap of pilot valve and the groove chamber of supporting or opposing is replenished, make main back of the body chamber pressure reach balance very soon, so spool (4) is tightly being pressed main valve seat under spring (20) effect.Then check spring (16) makes non-return core (18) also tightly press auxiliary-seat, when medium flows backwards, cut off by non-return core (18), and fine setting screw rod (10) rotation is withstood non-return core (18) to the motion of auxiliary-seat direction.Shorten and the auxiliary-seat distance, MEDIA FLOW is reduced to the rate of discharge of valve body (7).If be rotated further fine setting screw rod (10), then flow can be kept to zero.If fine setting screw rod (10) is to counter-rotation, the link (17) of pulling and non-return core (18) then makes the non-return core (18) and the distance of auxiliary-seat increase, and MEDIA FLOW is increased to the rate of discharge of valve body (7), as being rotated further again, just can lose the non-return effect.If rotate handwheel (12), drive crack screw rod (11) upward to motion, withstand spool (4) and make it to open, so medium imposes on the trying hard to recommend moving check spring (16) of non-return core (18) and makes valve opening, if crack screw rod (11) continues to move upward, then flow increases.
With reference to Fig. 2, be pipeline contact formula second embodiment.Valve body (7) inlet passage (oa) is gone up processing channel (of) with base (22) and is tightly connected, and valve gap passage (od) is tightly connected with valve outlet passage (oe).
With reference to Fig. 3, be pipeline contact formula the 3rd embodiment.Valve body (7) inlet passage (oa) is tightly connected with the passage (od) of valve gap (3), and the static iron core of pilot valve (23) passage (ob) is tightly connected with valve body (7) outlet passage (oe).
With reference to Fig. 4, be to contact directly formula the 4th embodiment.Valve body (7) inlet passage (oa) is tightly connected with static iron core (23) passage (ob).Valve body (7) inlet passage (oa) also can be tightly connected with valve gap (3) processing channel, also can be connected with the channel seal of base (22) processing.
Its operating principle and above-mentioned first, second and third kind embodiment's difference is that the pilot valve passage (od) of the formula of contacting directly and valve body (7) outlet passage (oe) are configured in spool (4) center.Drive unit (1) control armature (2) is gone up and is promoted spring (25) and promote the passage that Sealing (24) valve body (7) inlet passage (oa) and static iron core (23) passage (ob) are tightly connected again.Simultaneously, drive valve rod (26) and open pilot valve.Then drive spool (4) upper limit spare (27), so spool (4) is opened under the tension of valve rod (26) again both leading under the pressure difference effect of carrying on the back the chamber.Drive unit (1) control armature (2) moves downward, and valve rod (26) resets because of spring (25), closes the pilot valve hole, and spool (4) resets under action of gravity.
In order to prevent that medium from leaking from each joint, all seals between each connects.In order to be applicable to media such as poisonous, inflammable, under the very high situation of seal request, cover with cover cap in valve body (7) bottom.
Found out that by the foregoing description the structural type of improvement of the present utility model and pilot valve is irrelevant, therefore, pilot valve can be normal close type or open type or self-sustaining type.Also irrelevant with the pattern of spool simultaneously, can be diaphragm type or piston type.
