Description

The pipe coupling valve is program control, collection is controlled, emergent automatic control system

The present invention relates to pipeline, valve engineering, adopt the extension product of pipe coupling valve: the pipe coupling valve that surges, play the equilibrium valve of throttling, overflow effect, play the self-acting valve of emergent automatism, forms program control, collection is controlled, the automatic control system of meeting an urgent need.

Cutting from pipework today all is to form a pipework system with common stop valve, the opening and closing of valve, all must check one by one by operator, open one by one, close one by one, because carelessness, the time wrong unlatching phenomenon, solenoid valve is also arranged now, but owing to cost height, coil are easily damaged partss, limited by environmental conditions again, so solenoid valve can not replace common shutoff valve.

The pipe coupling valve has four characteristics: one, Yi Kaixing is arranged, close automatically.Two, this valve opening or to close be to utilize the variation in pressure of main valve plug epicoele and main valve plug cavity of resorption to realize that these characteristics just can be amplified out the self-acting valve product.Three, the outlet of this valve taps into a mouthful liquid stream, and balance port is closed valve, and then this valve can work as throttle valve and relief valve uses, and makes controlling plumbing fixtures form a stable liquid stream.Pay water intake and use if four, this valve has water main inlet port, pay water intake, then this valve can be formed compound program control, collection control, emergent robot device.

Based on the premises, the pipe coupling multifunction valve is a patented product, the patent No. is to be on September 26th, 92 922380813 applyings date of ZL, details about the pipe coupling multifunction valve, please check patent documentation, existing brief introduction is as follows: the pipe coupling multifunction valve has 8 mouthfuls of water main inlet ports to pay water intake 7, water outlet 11, balance port 1, adjust screw 2, main valve plug epicoele 3, valve rod 4, external tapping 5, main valve plug 9, main valve plug cavity of resorption 10 (see figure 1)s.This valve is to be used to surge the usefulness of Open valve, must increase the opening device that surges.Here it is on valve gap 12 bases, the Hydraulic actuator (see figure 2) of casting.It can pack into valve rod 4 in this Hydraulic actuator, then knob top has one by formula import 22, side has a pull-type import 25, valve rod 4 and Hydraulic actuator have seal ring 29, and valve rod 4 and valve gap also have seal ring 29, pull-type like this import and not connected by the formula import, usual only with a bite, the pipe coupling valve, add Hydraulic actuator after, become the pipe coupling valve that surges.The pipe coupling multifunction valve is a patented product, and is existing still in the protection period, utilizes pipe coupling multifunction valve and phase extension product now, forms program control, collection control, the robot device of meeting an urgent need, and has more science, practicability, so do application for a patent for invention.

The purpose of patent of the present invention: be exactly the extension product that adopts the pipe coupling multi-functional valve; The pipe coupling valve surges, play throttling, overflow effect compensation flap, play the emergent self-acting valve of automatism, as above other accessory, form one program control, the collection control, emergency automatic system, change existing valve system valve opening one by one, close, the phenomenon of checking, a but cover valve system, under the effect of surging, the unified unlatching, or unify to close automatically, also can form emergent robot device, some unit valve becomes hundred calculating, had program control, the collection control, valve also can be as electrical apparatus industry after the emergency automatic system, also can manage at central station of floating dock, like this, the accuracy that valve uses, Security improves greatly.Personnel can bring into play bigger benefit like this.

The purpose of patent of the present invention is to realize like this, first talk about the setting of program control device, as motor-drive pump 25 is the pipeline valve system of power source, be on the pipeline of the front of valve behind motor-drive pump and the pump, to tell a pilot line, press figure three stringings, make pilot line tell a, two pilot line of b, the a valve, the b valve is a main control valve, the a pilot line is by the throttling of a1 valve, the overflow of a2 valve, the a pilot line has a stable hydraulic like this, and this hydraulic pressure is greater than the elastic force 0.3kg of the main valve plug spring of a1, less than the elastic force 0.5kg of the main valve plug spring of a2, the a3 valve is a Decompression valves, and the pipe coupling valve that surges that it is controlled has valve 1, valve 2, valve 8, valve 9, valve 10.The b pilot line also has b1, b2, b3 valve, and the hydraulic tubing joint valve that it is controlled has valve 3, valve 4, valve 5, valve 6, valve 7.

The Changjiang river boats and ships use river in a large number, and pilot line advances river and I'm afraid that pilot line stops up, so pilot line is then quoted the pressure of clear water pressure steel cylinder 13, like this clear water pressure steel cylinder 13, add steel cylinder pressure inlets valve 18, reduction valve 17, valve c1, valve c.Motor-drive pump 22, valve 21 behind valve 20, the pump before valve c1, the pump, they are formed one and refute water system.If cut-off valve c1, valve c open, then valve c and b pilot line communicate, and valve b closes.Also controllable valve 3, valve 4, valve 5, valve 6, valve 7 of the hydraulic pressure of clean waterpump then.Emergency automatic system, by pipe coupling formula self-acting valve 19, emergent pipeline 27, valve 15, valve 16, pressure medium steel cylinder 14, motor-drive pump 25, valve 3, solenoid valve 3 ' reach medium box 12 to form.

Centralized control equipment is exactly valve a, valve b, valve c, valve c1 valve 3 ' make into solenoid valve, the starting drive of their switches and electric pump 25, electric pump 22 is moved on to central station of floating dock, each loine pressure table also moves up, then people can operate the unlatching of each valve at central station of floating dock, the unit of condition difference also can be by the external valve of the pipe coupling valve that surges, as valve 1 ' valve 2 ' ... valve 10 ', focus on also manual Open valve of working surface appropriate location, form external opening of valves valve system.

If the water intake 29 of paying of paying water intake 28, valve 4 of pipe coupling valve valve 2 is also used, also can form compound program control, collection control, emergent automatic control system.

The program control device working procedure is such: when power source, motor-drive pump 25 1 start.Valve produces a pressure behind the pump, because valve 2 behind the pump, to adopt back valve 4 are closed conditions, then pressure all enters controlling plumbing fixtures, if open a valve, when controlling plumbing fixtures pressure during greater than 0.3kg, backs down the a1 main valve plug.This hydraulic pressure enters into a pilot line, and a pilot line pressure is by the Hydraulic actuator of valve 1, valve 2, valve 8, valve 9, valve 10, make the valve opening of valve 1, valve 2, valve 8, valve 9, valve 10, the motor-drive pump commentaries on classics of not stopping transport, then the medium in medium pond 11 is extracted out from valve 1, entered the pipeline of branch pipe(tube) valve 8, valve 9, valve 10 through valve 2.When a valve cuts out, the b opening of valves, then the pilot pressure of b pipeline formation has also been opened valve 3, valve 4, valve 5, valve 6, valve 7, like this, the pressure of motor-drive pump also the medium in medium pond 12 from valve 3, by valve 4 enter valve 5, valve 6, valve 7, b pipeline pilot pressure makes the conducting of a3 valve simultaneously, a pipeline pressure releases like this, a pipeline is controlled closes and also closes automatically.

Emergent automatic control system working procedure is such: if that supposition figure three is a machine oil is program control, the collection control, when emergency automatic system pipe coupling valve is made self-acting valve, need balance port 1 sealing, machine oil main pipe by external valve and another diesel engine is connected, like this, the engine oil pressure of another diesel engine enters the main valve plug epicoele of self-acting valve.Work main pipe engine oil pressure is 3-4kg, and the engine oil pressure of emergency pressure steel cylinder 14 enters the main valve plug cavity of resorption of emergent pipeline 27 to self-acting valve 19 by valve 16, then the pressure of emergent machine oil generally keeps 24kg, when the machine oil decompression of the diesel oil of proper functioning, then emergent engine oil pressure drops to 1.5-2kg.The pressure of emergent machine oil steel cylinder be by should ceasing self-acting valve 19, and enters the machine oil main pipe 24 of diesel engine, keeps diesel engine and runs well.When machine oil steel cylinder pressure is lower than 1.5kg, then motor-drive pump and solenoid valve 3 ' startup automatically, motor-drive pump is just extracted the machine oil of sump 12 out, the emergent steel cylinder 14 of cracked ends, emergent pipeline 27, emergent self-acting valve 29 are not delivered to the diesel engine lubricating oil main pipe, keeping diesel engine runs well, if the oil pump of diesel engine is a secondary pump, stringing adopts program control way or prepares another electronic oil pump, also can normally keep diesel engine and run well.Final assurance boats and ships normally navigate by water.

The defeated controlling plumbing fixtures system that is pressed onto of clear water pressure steel cylinder, by 13 voltage supply of clear water pressure steel cylinder, at this moment open the c valve, close the b valve, then the pressure of clear pressure steel cylinder 13 is through being transported to the b controlling plumbing fixtures through valve c after reduction valve 17 decompressions, and motor-drive pump 25 1 runnings then also can be extracted out the water of medium box 12 by valve 3, through valve 4, and send among the pipeline of valve 5, valve 6, valve 7.Valve c1 and motor-drive pump 22, valve 20, valve 21 are formed a drying system, open c1, cut-off valve c then motor-drive pump 22 just the water of valve before the pump 20 is sent to the sump that valve 22 is controlled, several groups of methods, just by several controlling plumbing fixtures, program comes into plain view, and will not open mistake.

Central control device has two kinds, external valve 1 ' to valve 10 ' each valve put together, when valve 1 ', valve 2 ', valve 8 ' unlatching, then motor-drive pump 25 just the medium in medium pond 11 through valve 1, valve 2 and the pipeline of delivery valve 8, this is that external valve is manually concentrated open system.

Its controlling method of the control procedure of central station of floating dock is identical with manual program control controlling method, but, presses the knob of main control valve a, valve b, valve c at central station of floating dock, presses motor-drive pump 25, the knob operation of motor-drive pump 22.After emergent warning automatically, the past cabin of needn't being eager runs but observes the machine oil working pressure and the engine oil pressure variation of meeting an urgent need at central station of floating dock, after emergency system gets on, goes down to check failure cause, makes accurate decision again, is to continue navigation, the maintenance of still stopping.

If the utilization of paying water intake 28,29 of pipe coupling valve valve 2, valve 4 can also be formed compound program control emergency automatic system.The emergent automatic control system of another diesel engine of motor-drive pump may command.

Program control, the collection control, the appearance of emergent automatic control system, valve is checked one by one, open one by one, the operating method of closing one by one changes, make the valve engineering, can use pilot line, each same group of valve is stringed together, as long as the pilot line build-up pressure, then this same group of valve can be opened simultaneously, pilot pressure disappears, and then this group valve is closed automatically, and the switch of valve has accuracy like this, the appearance of emergent robot device, in the valve engineering, make risky operation, safety assurance is arranged, as diesel engine oil pressure, the pressure of can not breaking for one second is lower than 1kg operation 10 minutes, also the safety of entail dangers to diesel engine, after emergent robot device has been arranged, diesel engine one starts, but then the people is step-down, checks emergent robot device reliability.Just know what's what in the normal navigation, in staffing, the process of delimiting the organizational structure, can give full play to people's economic benefit.Leader, the masses are to jeopardizing diesel engine running safety, and catastrophe failure can be relieved.

This patent of invention occurs, it implement certain economic benefit, now a lot of boats and ships are engineers, two oilings, if drive automatically to implement, then personnel are just much of that with a people.The boats and ships of existing central station of floating dock are only then implemented valve operation at central station of floating dock with knob fully with a people.Because of the seawater decompression, the situation that the machine oil decompression causes diesel engine to damage can finish, operator on duty's technical quality can further reduce, so: the modern enterprise that pipeline valve is relatively concentrated, except that boats and ships, that boiler, chemical industry all can be used is program control, collection control, emergent robot device, and motor-drive pump power is enough, also can adopt compound program control, collection control emergency system in a large number.
