Description
Technical field
The utility model belongs to autocontrol valve, relates in particular to a kind of Pneumatic-control type Material valve that is applicable to liquid, gas or mixes the powder-material conveying.
Background technique
The valve that is used for control automatically generally adopts Pneumatic butterfly valve and pneumatic push-pull valve.Its processing ease, but poor sealing leak easily, and working life is short.Use pneumatic ball valve in the design,, and close freely though its normal temperature state seal performance is good.But when the medium temperature of flowing through raise, spheroid expanded, and the opening and closing resistance is big, influences the operation of valve, receives the medium temperature variable effect bigger.The above-mentioned various common especially common problem of valve: when the medium appearance temperature in the valve of flowing through changed, each component produced and expands in the valve, influences the flexibility of its operation.As: valve plate is long-term uneven wear that to-and-fro motion causes in valve body, and the valve plate surface grinds groove, influences the working life of valve.It is high in the logistics progress that liquid, gas or mixing powder-material are carried, to demand researching and developing a kind of wear resistance urgently, long service life, and flexible operation starts and closes sensitive autocontrol valve.
The model utility content
The utility model is in order to overcome deficiency of the prior art, and a kind of be applicable to liquid, gas and the conveying that mixes powder-material are provided, and wear resistance is high, long service life, and flexible operation starts and closes sensitive Pneumatic-control type Material valve.
The utility model is realized a kind of Pneumatic-control type Material valve for realizing above-mentioned purpose through following technological scheme; Comprise control unit, spool and valve body, it is characterized in that: the valve seat of said control unit and valve body is affixed, and said spool comprises contiguous block and the valve plate that places its both sides, adjustment piece and withstanding tight block; Said contiguous block middle part is connected with control unit; Said contiguous block is provided with circular hole along its horizontal axis, is equipped with the adjustment piece in the middle of the said circular hole, and said adjustment piece both sides are provided with withstanding tight block; Suit Returnning spring on the said withstanding tight block, said withstanding tight block end and valve plate madial wall touch.
The top that said withstanding tight block and valve plate madial wall touch is provided with the semicircle bulb.
Said control unit adopts control cylinder; Piston rod one end of said control cylinder is connected with the contiguous block middle part; Said cylinder vertically is provided with stuffing box along the piston rod direction, and filler is set in the stuffing box, and the box mouth of stuffing box is provided with the filler lid; One end of filler lid and the box body inside of stuffing box match, and the bottom of filler lid compresses the filler in the stuffing box.
Be provided with pressure spring between the end of said filler lid and the cylinder.
Beneficial effect: be applicable to liquid, gas and the conveying that mixes powder-material.When the medium appearance temperature of the Pneumatic-control type Material valve of flowing through changed, the expansion of each component did not all influence the flexibility of its operation in the Pneumatic-control type Material valve.Valve plate contacts with working surface between the valve seat closely, has improved the leakproofness of Pneumatic-control type Material valve.Compact structure, wear resistance is high, long service life, flexible operation starts and closes sensitivity.

Among the figure: 1, cylinder, 2, valve body, 3, valve seat, 4, valve plate, 5, withstanding tight block; 5-1, semicircle bulb, 6, Returnning spring, 7, the adjustment piece, 8, filler, 9, stuffing box; 10, filler lid, 11, pressure spring, 12, piston rod, 13, spool, 14, contiguous block.
Embodiment
Below in conjunction with preferred embodiment, details are as follows to the embodiment that provides according to the utility model: see accompanying drawing for details, a kind of Pneumatic-control type Material valve; Comprise control unit, spool 13 and valve body 2, the valve seat 3 of said control unit and valve body is affixed, and said spool comprises contiguous block 14 and the valve plate 4 that places its both sides, adjustment piece 7 and withstanding tight block 5; Said contiguous block middle part is connected with control unit; Said contiguous block is provided with circular hole along its horizontal axis, is equipped with the adjustment piece in the middle of the said circular hole, and said adjustment piece both sides are provided with withstanding tight block; Suit Returnning spring 6 on the said withstanding tight block, withstanding tight block lean on the elastic force of Returnning spring to hold out against valve plate.Said withstanding tight block end and valve plate madial wall touch.The top that said withstanding tight block and valve plate madial wall touch is provided with semicircle bulb 5-1.Said control unit adopts control cylinder 1; Piston rod 12 1 ends of said control cylinder are connected with the contiguous block middle part; One end of said cylinder relatively vertically is provided with stuffing box 9 along piston rod, and filler 8 is set in the stuffing box, and the box mouth of stuffing box is provided with filler lid 10; One end of filler lid and the box body inside of stuffing box match, and the bottom of filler lid compresses the filler in the stuffing box.Be provided with pressure spring 11 between the end of said filler lid and the cylinder.
Working procedure:
Cylinder is as the power of opening and closing Pneumatic-control type Material valve.When the piston rod of cylinder retracted in the cylinder, spool was along with the inwall of piston rod along valve seat promotes, and the Pneumatic-control type Material valve is opened, and Pneumatic-control type Material valve two ends communicate.When the piston rod of cylinder stretched out, spool resetted with the inwall decline of piston rod along valve seat, and Pneumatic-control type Material valve two ends are blocked by valve plate, and then the Pneumatic-control type Material valve is closed.
Link the other end of pressure spring and an end of cylinder, one end of the other end of filler lid and energizing spring links.Stuffing box upper part of the cover pressure spring applies certain pretightening force.The impacting force of pressure spring compresses filler through an end of filler lid automatically after the filler wearing and tearing, can make the Pneumatic-control type Material valve keep being in for a long time operation under the sealing state.Working principle:
Because two valve plates that are oppositely arranged compress by spring, so when the medium appearance temperature of the Pneumatic-control type Material valve of flowing through changed, the expansion of each component did not all influence the flexibility of its operation in the Pneumatic-control type Material valve.Valve plate has rotation function, whenever makes a round trip, and valve plate just has a low-angle rotation.Guarantee the valve plate uniform wear.Valve plate is in valve body long-term to-and-fro motion, guaranteed that valve plate contacts with working surface between the valve seat closely, has improved the leakproofness of Pneumatic-control type Material valve.The stuffing box portion of covering presses with spring, and gives certain pretightening force.After the filler wearing and tearing, the impacting force of spring compresses filler automatically, makes the long-time running of Pneumatic-control type Material valve still can be in sealing state.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technological scheme of the utility model.
