Description
Technical field:
The utility model relates generally to a kind of mechanical device, specifically is the air chamber of the instrument valve pneumatic actuator closing device when installing.
Background technology:
Pneumatic actuator is a part of instrument and meter for automation valve, and it includes membrane cover and following membrane cover, owing to the spring that has compressed that has the 4-6 root to be used to reset between the upper and lower membrane cover, the decrement of 20-30mm is arranged.At present, the conventional way of upper and lower membrane cover assembling is: two operative employees will go up membrane cover with hand and be depressed into down on the membrane cover after the closure, use bolted.Owing on streamline, can not carry out manual operations, and do more time-consuming, effort like this, influence the raising of productivity with two people.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, the closing device when providing a kind of air chamber of simple in structure, easy to operate instrument valve pneumatic actuator to install.
The utility model is achieved through the following technical solutions:
Closing device when the air chamber of instrument valve pneumatic actuator is installed, include frame, it is characterized in that: described frame includes upper backup pad, lower supporting plate and pillar, and pillar is fixed between the upper and lower gripper shoe, described pillar is with the slide plate that can slide up and down outward, and through hole is arranged on the slide plate; Be fixed with seat board on the described upper backup pad, there is the guide groove of left and right direction the seat board both sides, and having in the described guide groove can left and right mobile pressing plate, and described pressing plate front end is hook-shaped, and involutory surface is an arc; Described pressing back-end is equipped with set bolt, on the described bolt handle is installed; On the described lower supporting plate cylinder is installed, the piston rod of cylinder passes the through hole on the slide plate and fixedlys connected with slide plate; Described piston rod top is fixed with guide post, and guide post passes the through hole on upper backup pad and the seat board successively, and the guide post upper end is equipped with dismountable stop nut; Both sides, described slide plate bottom are fixed with tower respectively and buckle pin, on the tower button pin removable drawstring are installed, and described drawstring cover is on pneumatic actuator.
Closing device when the air chamber of described instrument valve pneumatic actuator is installed is characterized in that: on the described seat board through hole is arranged, the annular edge edge is arranged on the through hole.
Closing device when the air chamber of described instrument valve pneumatic actuator is installed, it is characterized in that: described guide groove be by go forward at seat board, the rear keeps at a certain distance away and is installed with clamping plate and forms, on the described pressing plate bar-shaped trough is arranged, have screw to be fixed on the seat board in the bar-shaped trough.
The compressed air that the utility model has filtered at first passes through valuator, enters the air inlet of the hand commentaries on classics of three of four-holes again, two mouthfuls of two air inlets up and down of connecting cylinder respectively of the output of this valve.The work function of four-hole threeway hand rotary valve is central enclosed type.Use central authorities' sealing function of four-hole threeway hand rotary valve and the compressed air holding function in the cylinder, keep a period of time, work convenient for assembly again.
Pressing plate of the present utility model can slide between two clamping plates, and its head is and colludes shape, with following membrane cover contact-making surface be arcuation.Its objective is compressing of the part that adapts to different-thickness.The gripper shoe afterbody is installed an adjustable branch head screw, and what link to each other with the screw top is one and has knurling handle, and loosen screw after fulfiling assignment and pull back, the air chamber parts that dismounting has installed, vice versa.
Before the assembling pneumatic actuator, earlier the following membrane cover of pneumatic actuator is sleeved on the seat board annular edge along outside, the pressing plate of mobile both sides makes it be clamped at down both sides, membrane cover lower end again, at this moment, pressing plate is on the base plate that hook-shaped head is pressed in down the membrane cover downside.The described handle of turn is gone into screw threads in the seat board again, plays the position-limiting action to following membrane cover.To go up membrane cover again and be pressed in down on the membrane cover, and make upper and lower membrane cover be in umbrella-waiting state.Then, the tower that drawstring one end is fixed on slide plate one side is buckled on the pin, again with drawstring upwards cover walk around whole pneumatic actuator to be assembled, the tower that the other end of drawstring is fixed on the slide plate opposite side is buckled on the pin at last.Upper and lower mobile drive slide plate by the cylinder upper piston rod moves along pillar is upper and lower, and the guide post that is fixed on simultaneously on the cylinder piston rod also can upper and lowerly thereupon move.When slide plate is moved down by instruction, drawstring drives upward with moving down of slide plate, and membrane cover moves down simultaneously, make the interior spring of membrane cover to lower compression, simultaneously, guide post also moves down, and the stop nut on the guide post can will descend the base plate under the membrane cover to compress gradually, plays the fixing effect of membrane cover down.When last membrane cover and following membrane cover are closed mutually, in the screw of membrane cover both sides up and down, penetrate bolt and fastening nut, making up and down, membrane cover reaches driving fit, dead-tight state.
The utility model is by the manual control valuator, moves down with the pressure-driven piston rod of valuator output, driven by belt simultaneously and goes up membrane cover and move down with following membrane cover and join the two sections of a bridge, etc, and promptly closes intake valve after the closure.Purpose with definite value is: be unlikely to produce excessive impulsive force when the last therapeutic method to keep the adverse qi flowing downward covers dragon, guarantee the security when the utility model uses.
The utility model has the advantages that:
The utility model adopts bigger cylinder, its objective is and selects lower operating pressure for use, does not produce too high noise when discharging compressed air, plays the effect of protection working environment.And solve heavy installation exercise, and developed a kind of novel approach, reduced the labour, improved production efficiency.
