Abstract
This invention relates to an automatic target plate device, which comprises a target, and a detachably-connected base of one end connected to a push rod that has a convex block and a sleeve with an opening and ends fixed connected with a long-travel actuator and a shut-off valve through a flange base respectively. Besides, it connects a short-travel actuator on the valve. By This invention, it is not necessary to close the steam pipe for steam check.
Description
Technical field
The present invention relates to a kind of mechanical hook-up, relate in particular to a kind of automatic target plate device that is applied to the detection cleaning steam degree on the steam flush pipeline.
Background technology
Adopt the steam flush pipeline very general now, when the steam flush pipeline, generally will detect the cleanliness of steam.The target plate that existing detection pipeline steam adopts mostly is rectangular slab, and its width is 8% of a pipe diameter, and the plate face of target plate is taken out detection with target plate then towards the airflow direction of steam, thereby determines the cleanliness of steam.Existing adopt manually of target plate that is used to detect the cleanliness of steam more, as shown in Figure 1, target plate 3 is fixed on the target plate seat 4, target plate seat 4 is welded on the blind flange 4-1, blind flange 4-1 adopts and is bolted on the jet chimney 12, after detection finishes, jet chimney 12 is closed cut steam, bolt is turned on and target plate 3 can be taken out.Adopt the target plate of this kind structure to detect, all jet chimney will be closed at every turn, and the check be high-temperature steam, be easy to have an accident.
Summary of the invention
The present invention mainly provides a kind of automatic target plate device that need not at every turn want the steam off pipeline with regard to energy Direct Test cleaning steam degree; Solve existing in prior technology troublesome poeration complexity, all want the technical matters of steam off pipeline at every turn.
The present invention simultaneously also provides a kind of safe, can remote-controlled operation, and the automatic target plate device that robotization is high; Solved exist in the prior art because vapor (steam) temperature is too high, misoperation causes the technical matters of scald etc. easily.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of automatic target plate device, comprise target plate and target plate seat, one end of target plate seat is connected on the push rod, target plate seat and target plate are provided with convex shoulder for removably connecting on push rod, push rod is provided with sleeve pipe outward, sleeve pipe is provided with opening, one end of sleeve pipe is fixedlyed connected with long stroke actuators, and the other end is connected with shut-off valve body by flange seat, also is connected with short stroke topworks on the shut-off valve body.Target plate seat and push rod are one, and the free end of push rod has just played the effect of target plate seat.Moving up and down of long stroke actuators control target plate, after detection finishes, target plate is promoted from the steam flush pipeline, this moment, short stroke topworks stretched out the spool of stop valve forward, make the runner sealing of stop valve, then target plate is taken out by the opening on the sleeve pipe, detect or change; When needing to detect, target plate is contained on the target plate seat, starts the piston motion in the short stroke topworks, the pulling spool is withdrawn, and opens the runner of stop valve, target plate is sent in the jet chimney by push rod by long stroke actuators again.Convex shoulder is set on push rod, can be when push rod drive target plate and enter jet chimney and the flange seat clamping, play sealing function, do not cause steam leakage.The target plate device of this kind structure, the operator can operate at a distance, and is safe and reliable, and do not need to block back and forth and open steam, easy to use, shortens the test operation time.
As preferably, described long stroke actuators and short stroke topworks are pneumatic drive mechanism, are connected by bolt between target plate and target plate seat.Certainly above-mentioned long stroke actuators and short stroke topworks also can be forms such as motor-driven, but the electric operator responsiveness is slower.Because target plate will be taken out detection, so must dismantle mutually between push rod and target plate, removably connecting between push rod and target plate can be known any-mode, connect clamping, transition fit connection etc. as bolt, adopt the bolt mode simply effective, cost is low durable.
As preferably, the circumferential surface of described push rod axially be provided with gathering sill, in flange seat, be provided with groove with the corresponding position of gathering sill, be provided with the orienting lug that matches with gathering sill in the groove, orienting lug is connected in the groove.Because the plate face of target plate must be met the direction to flow of vapor, thereby the direction of motion of push rod only allows rectilinear motion, by cooperating of gathering sill and orienting lug, prevented that push rod from rotating displacement in motion process, guaranteed target plate towards constant.
As preferably, the convex shoulder place on the push rod is a circular conical surface, is provided with the internal conical surface that cooperates with circular conical surface on the push rod at flange seat with the sleeve pipe joint.Taper surface processing is simple, and is concentrated littler than right angle unfair stress, and form the sealing pair of spool and valve seat, good sealing effect.
As preferably, the free end of target plate seat is round table-like, on flange seat, is provided with the internal conical surface that matches with the excircle taper surface of target plate seat with the stop valve joint.The free end of target plate seat is set to round table-like, be that before stop valve did not also cut out, the excircle taper surface on the target plate seat cooperated with the flange seat internal conical surface for when target plate is taken out in by jet chimney, form another sealing pair, prevent the steam leakage in the jet chimney.
Stop valve can be the through way valve of known arbitrary form, and as gate valve or ball valve etc., as preferably, stop valve is a wedge action valve.Wedge action valve hot conditions lower seal is effective.
As preferably, the end of described short stroke topworks is provided with manual-operating mechanism.In short stroke topworks, be provided with manually, in the time of can preventing from a single day to break down, adopt manually control short stroke topworks, thereby guarantee the normal switching of stop valve, normally the carrying out of target plate test job in short stroke topworks.
Therefore, the present invention has the following advantages: 1. reasonable in design, simple to operate; 2. safe, but remote-controlled operation; 3. it is convenient to change target plate, and open and close jet chimney repeatedly during detection has improved work efficiency, has reduced the detection cost; 4. automaticity height.
