The utility model has accurate detection, simple connection, few leading wire, convenient field detection and repair and replacement, and long service life, and the mounting position can be far away from the high-temperature zone.
Description
The utility model relates to a kind of sequencing valve valve position detection device, and it can accurately detect the valve opening and closing state.
Along with the raising of industrial production automation level, the Security of production process and reliability are the problems that people must face and solve, and controlling as the valve opening and closing status detection of sequencing valve is exactly one of them.At present, the device that detects the valve opening and closing of control sequencing valve all is to adopt non-self-retaining detecting sensor, as non-self-retaining Hall magnetosensitive detecting sensor used among the CN2055202U disclosed " position sensing formula oil hydraulic cylinder ".Because non-self-retaining detecting sensor characteristic is limit, a detecting sensor can only reflect a position information, detect simultaneously to open and close two position informations, just must install respectively at the respective detection position.Obviously, this not only will increase cost, causes lead-in wire too much, also will increase the installation and maintenance workload.In addition, for CN2055202U disclosed under the oil hydraulic cylinder casing wall technological scheme of position installation and measuring sensor, owing to processing or installation reason, still can't realize at present, so can only realize detecting the information that valve reaches the position, and the more important thing is that detecting valve closes the information that puts in place in the control automatically; Secondly, because the induced magnetism bloom is positioned at hydraulic jack, so the scene can't be changed.In addition, also what deserves to be mentioned is except that the disclosed scheme of CN2055202U, its mounting point of detecting sensor of all detection sensing valve open and-shut modes all is positioned at the middle and lower part of valve body support at present, thereby it is nearer from valve body, in the time of can't avoiding carrying high temp objects in high-temperature zone that the valve body surrounding environment forms, so easily make aging, the fusing of lead wire insulation layer, cause short circuit, detect malfunctioning and the damage of detector high temperature.
Task of the present utility model is to solve the problem that prior art exists, for the detection of sequencing valve control provides that a kind of connections is simple, lead-in wire less, the on-the-spot replacing conveniently can accurately be detected the valve position detection device of valve opening and closing two states information simultaneously again, and can also make the mounting point away from the high-temperature zone.
Task of the present utility model is finished by following technical proposals.
The utility model comprises self-retaining detecting sensor, the detection piece of pairing induction with it, seat board and valve position transmission rod.Bearing plate level cover is connected on the execution bar that is connected with the valve switch drive unit.Valve position transmission rod and vertical connection of external part of propping up seat board are installed the detection piece that shows the valve position opened and closed positions on it.When an execution bar drive seat board that is connected with the valve switch drive unit moves up and down, detect piece and promptly move up and down, and respond to rack-mount self-retaining detecting sensor with the valve position transmission rod, provide the valve opening and closing signal.
Accompanying drawing be structural representation of the present utility model and with the connection schematic representation of sequencing valve.
Be example with self-retaining Hall magnetosensitive detecting sensor below, also the utility model is described in further detail to provide embodiment in conjunction with the accompanying drawings.
The sequencing valve of the utility model indication mainly is made of valve body (1), support (2), valve switch drive unit (3).Support (2) is fixed on the valve body (1), and the execution bar (4) that is connected with valve switch drive unit (3) links to each other with valve rod (6) by a connector (5).Valve switch drive unit (3) can be oil hydraulic cylinder or motor.Present embodiment valve switch drive unit shown in the drawings (3) is an oil hydraulic cylinder, and corresponding coupled execution bar (4) is a piston rod just.
The utility model that is installed on the above-mentioned sequencing valve comprises self-retaining Hall magnetosensitive detecting sensor (7), the detection piece that matches with it---magnetic steel ingot (8), seat board (9) and valve position transmission rod (11), see accompanying drawing.Prop up seat board (9) level cover and be connected on the piston rod (4) of oil hydraulic cylinder (3) bottom, can move up and down with piston rod (4).Valve position transmission rod (11) is vertical to be connected on the external part that props up seat board (9), parallel with piston rod (4).When a seat board (9), can conduct out with the valve opening and closing state when moving up and down with piston rod (4) by it.Valve position transmission rod (11) is connected or welds with a seat board (9) but threaded screw.Magnetic steel ingot (8) has two, is embedded in the inboard of valve position transmission rod (11) respectively, and two displacement terminal points that reflect when its setting-in position puts in place with valve opening and closing are consistent.For valve position transmission rod (11) moving direction is remained vertically,, a guide plate (10) has been installed in the corresponding position level at support (2) top with the accuracy that guarantees to detect.The external part of this guide plate (10) has a hole, valve position transmission rod (11) is positioned at wherein just, and can freely moves up and down again.One vertical fixed plate (12) is arranged on the fixed end of guide plate (10), and plate also has a hole on (12), and the tail end of self-retaining Hall magnetosensitive detecting sensor passes this hole and is fixed on the plate (12).
When valve closes when putting in place, the magnetic steel ingot (8) of valve position transmission rod (11) epimere setting-in is just in time relative with self-retaining Hall magnetosensitive detecting sensor (7), position as shown, and at this moment, detecting sensor (7) produces a signal and exports.When need were opened valve, the oil hydraulic cylinder of sequencing valve was started working, and piston rod (4) rises, and drove to prop up fast together in the same way rising of valve position transmission rod (11) that seat board (9) is mediated.Because the detecting sensor (7) that adopts is the self-retaining detecting sensor, so before the magnetic steel ingot (8) of the setting-in on valve position transmission rod (11) hypomere is not corresponding with the detecting head of detecting sensor (7), the output that detecting sensor (7) keeps previous signal always.Thereby the magnetic steel ingot (8) that has only setting-in on valve position transmission rod (11) hypomere rises to the induction of aliging with detecting sensor (7), and previous signal just disappears, and is substituted by the signal of another new generation.Closing of valve is also like this.
Thereby, the utility model has the advantages that: 1. use a detecting sensor just can accurately detect valve opening and closing two states information simultaneously, so cost is low, it is simple to connect, lead-in wire is few; 2. because checkout gear all exposes outside, if any damage, site examining and repairing is changed convenient; 3. detecting sensor is positioned at a top of the trellis, and the high temperature damage of detecting sensor has been avoided in the high-temperature region that produces during away from the conveying high-temp liquid and lead-in wire is aging, melting phenomenon, has prolonged service life.
