5. owing to adopt the piston type pressure-regulating device more more economical than the bulge of employing rubber, reliable, applicability is better.And tiny leakage appears in the sealing of piston type guide pin bushing, because forced opening-closing mechanism assist location is arranged, usability is unaffected, if valve only is used for the occasion of standard-sized sheet full cut-off, can cancel Sealing on the piston type guide pin bushing.

6. because the open-shut device profile adopts cone or cylindrical body, streamlined structure is adopted with the medium surface of contact in the bucket end, and gate opening/closing process flow resistance is little, and it is big that the bottom produces lifting force, opens faster more laborsaving.

7. because the start and stop lever sealing surface adopts cone or end face seal face, the different sealing surface of seat contact seal part life-spans of gate opening/closing process are long.

8. owing to adopted contactless sealing formerly of circular groove and O-ring seals in motive sealing measure afterwards, and adopted axle journal and end face double-sealing or the measure of cone fixing seal in pilot valve, sealing reliability is higher, more can adapt to the high pressure working condition requirement.

9. because the follower of the rack-pinion of the no self-lock ability of employing itself can not influence automatic on-off and automatic sealability, also needn't worry owing to the medium temperature rise, the locking phenomenon that variation in pressure causes, positive operation are also safer, laborsaving, quick.

10. as long as change the valve material or with medium contact surface material or sealing surface material, and the related process measure just can adapt to the usage requirement of various liquid state, gaseous state, high temperature, low temperature or different medium pressure.

11. easy to maintenance, generally product need not be disassembled from pipeline during middle light maintenance.

Using method of the present invention and working principle

With first embodiment serves as that second embodiment's using method in basis and principle are identical.See Fig. 1:

1. automatic function

(1) medium automatic starting gate IIa

Rotate counterclockwise bulb handgrip 49, the block that pin 50 is on barrel lock start and stop lever 37 " leaves " position, at this moment the medium channel level mouth of pilot valve core 32 among the gate IIa, passage relative (this state claims pilot valve to open) with media outlet end B cylindrical body pilot valve valve seat 29, and the passage of the cylindrical body pilot valve valve seat 29 of media outlet end A is sealed, the medium that flows in the gate on the pipeline is cut off, and medium is discharged from the gate IIa, medium pressure descends rapidly in the gate IIa, and gate IIa outer bottom medium pressure is kept with medium pressure in the inlet line and is equated, this medium differential pressure begins to force gate IIa to rise, and (this moment, gate opening/closing regulator VI locking mechanism should be in open mode, be gear, tooth bar vice division chief is in the servo-actuated state).Uphill process is owing to a medium in the bucket door IIa continues loss, and the inlet line MEDIA FLOW produces a lifting force (bottom is streamlined profile) through gate IIa bottom, continues to force gate IIa to rise, and stops to liquid level, gate IIa reaches the extreme higher position, thereby realizes the automatic open function of medium.

(2) automatic closed shutter IIa of medium and gate IIa are from motive sealing

Bulb handgrip 49 is changeed 180 ° clockwise to the off-position, this moment, outlet end B cylindrical body pilot valve valve seat 29 passages were sealed, and the passage of entrance point A is opened (this state claims pilot valve to close), owing between the circular cone sealing surface of enable possition gate IIa is with the circular cone sealing surface of valve seat 2, exist than large space, and bucket door IIa bottom is on the liquid level, enter in the gate IIa along this space so medium is very fast in the pipeline, and very fast being filled, at this moment medium is in the sealed pressure state in the bucket, and the medium of bucket at the end of gate IIa is in flowing state, in the gate medium pressure greater than gate at the bottom of outer medium pressure, add the upper lock gate own wt, make gate decline, after the decline, the interior medium of gate is got back additional, and gate descends again (this process is carried out continuously), to cooperating fully with sealing surface on the valve seat 2.This moment again since the medium effective pressure area in the gate greater than the outer medium effective pressure area (Vertical direction) of gate, the interior pressure greater than external pressure, this pressure reduction forces gate IIa sealing surface tightly to press to the sealing surface of valve seat 2, reaches that medium is closed automatically, automatic sealing function.

(3) Flow-rate adjustment

When gate IIa closed condition, pilot valve is opened, medium flows out media outlet pipeline B in the gate, medium pressure loss in the gate, gate rises, during to needed height, pin 50 on the bulb handgrip 49 is gone to 90 ° of block on barrel lock start and stop lever 37 i.e. (this state claims the pilot valve throttling) on " accent " position, then the medium import all seals up with the medium channel mouth that exports pilot valve valve seat 29 in the gate, the interior medium of gate is maintained in the corresponding volumetric values, owing to the gate inner chamber seals, according to the incompressible principle of liquid medium, gate no longer rises, limited live.Thereby reach the function of regulating flow.Owing to gas compressibility, Flow-rate adjustment also needs by auxiliary carry out (face as follows) of enforement mechanism for gas medium.

2. enforcement functionalities

(1) unlatching and automatic sealing station are forced the location automatically

When valve is in automatic unlatching or automatic sealing station, gate opening/closing regulator VI is gone up bulb handgrip 14 screw clockwise, then the axle of shaftgear 13 is in advance by springhole locking on the elastomer, and unlatching and automatic sealing station are forced to locking automatically.

(2) force auxiliary gate from operation of motive sealing automatic on-off and Flow-rate adjustment

When operating mode is abominable, the automatic sealing load of gate appears when not enough, can use handwheel 16, artificially handwheel is applied a moment, to the gate sealing surface, produces an additional seal power by gear rack adjutant transmission of torque, reach and force to assist close property effect; Automatically open operation painstaking (overcoming gate deadweight and sealing pair frictional force) when gate occurring, also can adopt handwheel 16, auxiliary by force gate opening, back locking as the very little medium differential pressure deficiency of medium pressure; Gate opening position (as factor affecting such as seal fails on the guide pin bushing 26 in because of gate) not in place in automatic flow is regulated, occurs or tremble (pressure medium in the enable possition, the flow velocity instability), after also can forcing gate to be raised to definite position by rack-and-pinion, force locking by hand wheel 16.

Except that last, when only being used for standard-sized sheet, valve opens use occasion entirely, should adopt enforement mechanism as far as possible, when opening, force the gate bottom to leave the liquid level certain distance, to avoid impacted by high pressure, high speed medium, increase the service life.

Above-mentioned positive operation must be based on the running automatically of pilot valve control media.Could be laborsaving, energy-conservation.
