Description
Technical field
The present invention relates to the controlled valve that uses in a kind of pneumatic transmission pipeline, particularly be applicable to the controlled valve in the train air brake equipment.
Background technology
In railway transportation, braking is well-known to the vital function of guaranteeing traffic safety.The basic air brake equipment that adopts of countries in the world railroad train braking, brake gas are to rely on the pneumatic circuit of installing ON TRAINS to connect.Angle cock is one of vitals on locomotive and the car brakeing main line, it is installed in the two ends of locomotive and vehicle main brake pipe and brake hose is installed, and the coupling that with the brake hose other end O-ring seal is housed between locomotive and vehicle and vehicle and the vehicle connects and connects.When the operation of unitor seal ring is changed in the decomposition of train, marshalling or maintenance, must rely on angle cock frequently to open or close vent passage between the person in charge and the flexible pipe.Angle cock is closed because of need of work and is called as " normally closing ", and train finishes angle cock that the whole run duration strictnesses after the marshalling forbid and is closed situation (containing half pass situation) and is called as " improper cutting out ".In case train coupling cock is closed by improper, the driver just loses the control ability to train braking, causes train colliding thus, puts that grave accident such as to raise, overturn of common occurrence.Prevent that the improper technical study of closing of angle cock is called as " anti-pass technology ".Cause the improper principal element of closing of angle cock can be divided into four classes: 1, the hook of rope, tarpaulin twines and causes handle drive plug core to be moved to half pass or complete shut-down state; 2, wandering, escort personnel climbing scrunches and arbitrarily pulls and causes half to close or the complete shut-down state; 3, artificial destruction causes Sai Men to be the complete shut-down state; 4, the careless general idea of service work personnel cause adjacent two angle cocks having a double meaning, singly open or half-open position.In order to prevent the improper harm that causes of closing, extensively carry out anti-research of closing technical elements both at home and abroad, the various concept studys of comprehensive analyses can be divided into three major types substantially: the first kind is that traditional angle cock is undergone technological transformation, what have installs the locking spring additional at the handle head, the method of the employing locking and pressurizing that has, what quantity was maximum is various air draft braking schemes.These concept study major parts are to adopt traditional back and forth to pull 90 ° of operating mode of closing or opening or with the method for pressure air discharging directly into atmosphere, all design effect that can not obtain to expect.Angle cock can only be when manufacturing default unified fixing exhaust air rate, any one fixing exhaust air rate obviously can't adapt to different discharge capacity requirement of each time before, during and after the train.Excessive, the technical barrier that is difficult to remote transmission of pad value when replenishing the blast state braking ripple transmits with air wave is reverse down, generally solve as the too little problem of exhaust air rate, and according to the theory of " implementing the air draft braking; the sectional area of angle cock vent must be equal to or greater than locomotive and fill wind hole sectional area ", the concept study of a collection of big exhaust air rate has appearred.Find that through Chinese patent retrieval the patent No. is CN93214462.4, the utility model patent that name is called two ball type angle cocks still fails to solve scheme all unescapable out-of-control phenomenon with the pressure emptying when closing of big discharge capacity, causes difficulty to normal operation.Because plug door slowly must be opened the high pressure gas that just can avoid filling in Men Yiduan when normally opening rushes at low pressure one end fast and causes pressure drop to break through to limit numerical value, the scheme of these big discharge capacities is all continued to use and traditional is back and forth pulled the method for operation that opens or closes in 90 ° of scopes, when opening, also trigger the train braking system sensing unit so none is escaped by luck, to comprise the full train braking main pipe pressure emptying of locomotive, and have a strong impact on train running on scheduled time and send.The contriver once design-calculated patent No. is CN96115748.8, name is called the patent of invention of " anti-shutting one way linking door ", its method also is to carry out the air draft braking with big discharge capacity exhaust hose one terminal pressure air to be anti-pass measure, when result of study confirms unidirectional exhaust hose one terminal pressure air, even strengthen the vehicle that discharge capacity still can not be passed to the contrary air wave direction of braking ripple close locomotive fast, can only cause the triggering emergency brake to cause difficulty and have a strong impact on train running on scheduled time to normal operation sends, can not eliminate tarpaulin automatically, the rope hook twines class and wandering, the escort personnel climbing scrunches the influence of class factor, also the technological prevention measure is studied or is taked in the responsible accident that the careless general idea of service work personnel is not caused, as yet when the terms of settlement that must slowly open when normally opening of research and upkeep operation the secondary air draft trigger emergency brake and full train braking main pipe pressure be disposed to the terms of settlement of 0Mpa, so do not reach the technical merit of practical application as yet; Second class is to set up mechanical caging or pressure locking equipment on vehicle, because of reequiping and the strick precaution effect of evaluation prediction is also undesirable fails practical application original vehicle; The 3rd class is various electronic monitoring devices, there are problems such as poor reliability, warning hysteresis and life-span, economy, maintenance, management, along with the train braking system air-tightness is updated and is improved, the problem that lags behind of reporting to the police will be more serious, serious consequence often has been difficult to avoid when alerting signal is sent, powerless to taking precautions against the particularly expert crime of artificial destruction, train is carried out the all-the-way tracking monitoring cause huge fund, the wasting of resources in order to take precautions against possible moment incident.

Technical essential of the present invention: ratchet device is set active handle and must push-and-pull just can be finished shutoff more than twice or twice or open (following is the example brief description to set twice), when being set at twice, positive stop limit active handle at 45 ° with the interior slip of can only back and forth dallying, must push away and snap into 50 ° of left and right sides positive stops and ratchet can be headed in the ratchet engaged tooth, active handle drives ratchet device and stirs rotating shaft and plug core spheroid and the synchronous unidirectional rotation of regulation and control air draft blade, can only rotate 45 ° at every turn, when active handle rotated once more, hook tooth made active handle recover the idle running sliding mode ratchet jack-up.Ought rotate 45 ° for the first time during the shut-off plug door, the plug core spheroid is in half off status, main channel and both sides air draft groove all are inclined cross on big small sealing ring, the pressure air part at plug door two ends enters in the cock body cavity by both sides air draft groove, a part is walked around big small sealing ring edge and is entered the cock body cavity, a part enters the cock body cavity along the edge, main channel after mixing again in the main channel, this two-way exhaust method that adopts first makes to be closed no matter angle cock is in the car anteposition or Che Houwei can make the pressure air in the train rear portion car brakeing person in charge volume have the characteristic of replenishing blast from locomotive, thoroughly eliminated the contradiction that additional blast and volume are pressed, actv. has dwindled the difference in size of train front portion with rear portion pressure drop peak value simultaneously, because the shock damping action of regulating control exhaust valve, the pressure at two ends air continues combined balance system in the cock body cavity, further dwindled the difference of pressure at plug door two ends, the excessive transmission of pressure curve of pad value when the method for this two-way air draft combined balance system pressure of evidence has effectively changed the reverse transmission of braking ripple and air wave, solved the reverse remote technical barrier that transmits that is difficult to, obtain to guarantee to brake the ripple pulsation-free behind the comparatively straight pressure curve and be delivered to the train distal-most end that comprises locomotive, before also thoroughly having eliminated train, in, different the differences that require in back to the air draft braking, make arbitrary angle cock all can adapt to any parking stall, time working condition requirement, regulate and control the corresponding conducting of big vent of main vent with the regulation and control air draft seat of air draft blade this moment, low-keyed with the pressure air exhaust to atmosphere behind the combined balance system and send sharp-pointed exhaust sound, adjust the diameter dimension of setting regulation and control air draft blade master vent and add that the exhaust air rate of the small vent in center can obtain the best exhaust air rate of two-way air draft, realizes reliable and stable full train pressurize conventional brake; When rotating 45 ° for the second time, the plug core main channel is in off state, the air draft groove on right side is by the large sealing packing ring complete closed, finish the blocking fully that train braking is responsible for, the air draft groove in plug core left side is across on small sealing ring, the pressure air of hose end is entered in the cock body cavity, regulate and control the corresponding conducting of big vent of secondary vent with the regulation and control air draft seat of air draft blade this moment, with the low-keyed exhaust to atmosphere of the pressure air of hose end, also discharge a spot of pressure air owing to regulate and control the main vent of air draft blade this moment with the dislocation slit of regulation and control air draft seat center concave station and the small vent in center that connects all the time, so, the secondary vent diameter dimension of adjusting setting regulation and control air draft blade adds that the float wind bore dia size at regulation and control air draft seat concave station center can obtain the best discharge capacity of unidirectional air draft, guaranteeing not recover normally open-minded, when the car brakeing of train rear portion can not be alleviated, successively close the angle cock in adjacent two workshops and just can finish nothing pressure apportioned effort; When rotating once more; Sai Men is in the process of opening; regulate and control the secondary vent of air draft blade this moment and regulated and control the sealing of air draft seat; stop pressure air row to atmosphere; make it suitable fully requirement of slowly opening; before the paired angle cock of adjacent two cars is opened fully; the rear portion train can not fill wind to be alleviated and has at least the small vent in regulation and control air draft blade center of an angle cock and main vent and the dislocation slit of regulation and control air draft seat concave station can discharge the pressure air of a threshold quantity by the little vent at regulation and control air draft seat concave station center; send prompt tone simultaneously in order to remind the operating personnel that two plug doors are open-minded fully; effectively avoid because of singly opening or half-open accident that careless general idea causes; adopting the small vent in blade center and 3 air drafts simultaneously in two dislocation slits is in order to prevent that molecule or greasy dirt obstruction in the gas circuit from causing air draft not smooth; adjust the float wind bore dia size of setting regulation and control air draft seat concave station center and can obtain to open the best exhaust air rate of operating mode prompt tone air draft; big small sealing ring is finished the air-tightness effect to globe cock's core main channel after adjacent two plug doors are all opened fully; this moment, the regulating control exhaust valve was discharged the excess pressure air in the cock body cavity; avoid main air passage parts in addition to bear invalid pressure; artificially stopped up in order to take precautions against vent, regulating control exhaust valve outermost layer is equipped with the air draft protective cover plate.
The beneficial effect that compared with prior art the present invention had is: overturning naturally downwards behind the backing pin sheet insertion locking hanging nose of angle cock of the present invention is the active handle of lockable, prevent its accidental perk, with spring cotter insert means of defence that the locking hanging nose carries out the secondary locking to backing pin sheet and active handle replace Chinese passenger vehicle must be with the original method of twice iron wire binding plug door knob, more safe and reliable and reduce material consumption.Even under the situation of not inserting backing pin sheet and spring cotter, upwards vertically perk when active handle is subjected to mal external force, to vehicle outside is to rotate halt point, slide with interior idle running to 45 ° of vehicle interior side, plug core is not all made means of defence that operating mode rotates and can be broken away from the hook of rope tarpaulin automatically and twine and eliminate automatically influence wandering, that the escort personnel climbing scrunches and arbitrarily spur the two big improper factors of class, alleviates the work capacity of staff's cross-check sum recovery nominal situation in the time of guarantee driving safety.
The present invention carries out comprehensive automatic monitoring and strick precaution to the standard-sized sheet-half pass-complete shut-down-half-open-standard-sized sheet operating mode of plug door: when meeting with artificial broken ring, even pulling out the backing pin sheet according to operation requirements pushes away active handle and snaps into about 50 °, because each pulling is limited in 45 ° of scopes, this moment, plug core was in the two-way air draft operating mode of half off-position, the locomotive compression indicator is shown to the locomotive bus attendant with this information immediately, the automatic immediately pressurize conventional brake of rolling stock that comprises locomotive, train can not send, demolition purpose can not reach, simultaneously angle cock sends continual air draft chimes of doom guiding staff and needn't can follow sound by an inspection and rush for the crime parking stall and arrest the bad person and recover nominal situation rapidly, guarantees that train running on scheduled time sends; If broken toroidal molecule continuation operation will be filled in door and be closed fully, this moment, plug core entered the unidirectional air draft operating mode in complete shut-down position, the train rear portion autobrake, do not recover nominal situation and can not fill wind and alleviate, train still can not send, demolition purpose still can't reach, and the chimes of doom that continues to send forces the saboteur to flee the scene as early as possible.If closing adjacent two workshops simultaneously, the saboteur fills in door in pairs, (10～40Pa/S) must trigger the chain reaction of emergency brake because of the two plug door exhaust air rate sums of setting break through the pressure drop rate of stipulating, comprise the automatic immediately emergency brake of the full train of locomotive, demolition purpose still can not reach, this automatic immediate means of defence also makes the destruction of decomposing running train cannot succeed, because can cross over the two-way air draft operating mode of half off status, the unidirectional air draft operating mode of complete shut-down state in no instance and open prompt tone air draft operating mode before fully.Destruction to other all kinds of improper factors is also played deeper protective action, and does not need to increase any containment facility and expense, and the technical guarantee of economic and reliable is provided for train operating safety.
The present invention also can increase substantially the safe in operation level of normal operation; when carrying out train apportioned effort or maintenance hose coupling replacing seal ring; the paired angle cock that need successively close adjacent two workshops decomposes unitor then; when the two-way air draft operating mode of half off-position realizes that automatically full train pressurize is braked; the locomotive compression indicator clearly is shown as " pressurize braking " and reminds the locomotive crew member to note protecting the safety of operating personal; angle cock is closed the back interior pressure air of exhaust hose automatically in pairs; effectively alleviate the labour intensity that decomposes unitor; avoid the casualty accident of hold-off pressure bounce-back in the past; simultaneously; train is anterior because the benefit wind effect of locomotive recovers normal pressure and alleviation immediately; because of can not get mending wind, the train rear portion can not alleviate; train still can not start; this is just effectively avoided, and the train accidental activation damages the operating personnel in the upkeep operation; after carrying out apportioned effort, the car team that is decomposed can prevent effectively that because of being in the pressurize braking mode " runaway " accident from taking place.Because the present invention has realized automatic pressurize braking on angle cock, can recover normal pressure rapidly and recover to alleviate automatically in the normal pressure once recovering nominal situation, so can and not dispatch a car on schedule and cause hell and high water or negative effect to normal operation.
The present invention adopts the method for 360 ° of unidirectional rotations, expand traditional opereating specification of only in 90 ° of scopes, back and forth rotating to 180 °, be able in double amplitude, be provided with multiple function or measure of control, in cooresponding 180 °, repeat to be provided with the reliability that not only significantly improves various functions, and effectively reduce the volume and weight of product, experimental prototype of the present invention is than traditional taper angle cock expendable weight more than 35%, aim at passenger vehicle design-calculated experimental prototype reduction weight especially up to more than 50%, effectively reduce manufacturing cost; Because do not have easily worn part and select for use material (for example polytetrafluoroethylene or modified Teflon) to make seal ring with self-lubricating property, can avoid routine maintenance maintenance and release regular coating 295 silicone grease and eradicate the defective that " locking " phenomenon easily takes place common ball-type angle cock, effectively reduce service expenditure.More any angle cock more met physical activity rule and the equal easy manipulation of right-hand man but active handle position of design-calculated of the present invention and operation amplitude were than in the past, effectively reduced labour intensity.
