Abstract
The utility model relates to a material valve. The utility model consists of an air cylinder, a valve core and a valve body, wherein, one end of the air cylinder is connected with the middle of one end of the valve seat of the valve body, and one end of the air cylinder piston rod is connected with one end of the valve core. A setting block, an offsetting spring, a tightening block and valve plates are oppositely arranged in the valve core, a packing box, padding, an enforcing spring and a packing box cover are longitudinally arranged on one end of the air cylinder along the piston rod. The utility model has the advantages of rational design, compact structure, high wear resistance, long service life, flexible operation and sensitive start-up/closing. Because the two valve plates oppositely arranged are tightened by the spring, expansion of each part in the material valve would not affect the flexibility of operation when the media flowing through the material valve undergoes temperature fluctuation. When the padding is worn, the pressing force of the spring automatically makes the padding tightened, so that the material valve can still in a sealed state after a longtime operation. The utility model is suitable for transportation of liquid, gas and mixed powder material.
Description
Technical field
The utility model relates to a kind of poppet valve, relates in particular to a kind of Material valve.
Background technique
At present, being used for the automatic valve of controlling has: pneumatic ball valve, Pneumatic butterfly valve and pneumatic push-pull valve.When pneumatic ball valve uses at the normal temperature state, good airproof performance, and close freely.When the temperature of the medium of flowing through raise, spheroid expanded, and the opening and closing resistance is big, influences the operation of valve, is subjected to the medium temperature variable effect bigger.Though the gap of ball valve can be adjusted, technical difficulty is big, is difficult for grasping.Though Pneumatic butterfly valve and pneumatic push-pull valve processing ease, poor sealing is leaked easily, and working life is short.
When temperature variation appearred in the medium in the valve of flowing through, each component produced and expands in the valve, influences the flexibility of its operation.Valve plate is long-term to-and-fro motion in valve body, will cause uneven wear, can grind and collude groove, thereby influence the working life of valve.Packing seal is generally adopted in sealing between the conventional cylinder class part, and tight, after using a period of time, the filler wearing and tearing after leaking appears in valve, need the bolt of filler lid is tightened the filler lid by bolt, and this operation is cumbersome.
Summary of the invention
Main purpose of the present utility model is to solve the problem that above-mentioned valve exists, and a kind of be applicable to liquid, gas and the conveying that mixes powder-material are provided, the wear resistance height, and long service life, flexible operation starts and closes sensitive Material valve.
The technological scheme that its technical problem that solves the utility model adopts is:
Be made up of cylinder, spool and valve body, an end of cylinder is connected with the valve seat of valve body, and the piston rod of cylinder and the contiguous block of spool link.
The spool middle part is provided with the adjustment piece, and the both sides of adjusting piece are oppositely arranged Returnning spring, and an end of Returnning spring links with the adjustment piece.
The other end at Returnning spring is oppositely arranged withstanding tight block, and an end of the other end of Returnning spring and withstanding tight block links.
The both sides of spool are oppositely arranged valve plate, and the other end of withstanding tight block is connected with an end of valve plate, and withstanding tight block holds out against valve plate by the elastic force of Returnning spring.
Cylinder is as the power of opening and closing Material valve.When the piston rod of cylinder was done the action that retracts in the cylinder, spool was along with the action of the piston rod inwall along valve seat promotes, and Material valve is opened, and the Material valve two ends communicate.When the piston rod of cylinder was done the action of stretching out cylinder, spool resetted along with the action of piston rod descends along the inwall of valve seat, and the Material valve two ends are blocked by valve plate, and then Material valve is closed.
One end of cylinder relatively vertically is provided with stuffing box along piston rod, and filler is set in the stuffing box, and the box mouth of stuffing box is provided with the filler lid, and an 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.
One end of the other end of filler lid and energizing spring links, and an end of the other end of energizing spring and cylinder links.
Stuffing box upper part of the cover energizing spring applies certain pretightening force.After the filler wearing and tearing, the impacting force of energizing spring compresses filler by an end of filler lid automatically, can make Material valve keep being in for a long time operation under the sealing state.
During use, when needs are opened Material valve, start cylinder, when the piston rod of cylinder was done the action that retracts in the cylinder, spool was along with the action of the piston rod inwall along valve seat promotes, and Material valve is opened, and the Material valve two ends communicate.
When needs are closed Material valve, start cylinder, when the piston rod of cylinder was done the action of stretching out cylinder, spool resetted along with the action of piston rod descends along the inwall of valve seat, and the Material valve two ends are blocked by valve plate, and then Material valve is closed.
The utility model is a Material valve.Be applicable to liquid, gas and the conveying that mixes powder-material.Reasonable in design, compact structure, the wear resistance height, long service life, flexible operation starts and closes sensitivity, because two valve plates that are oppositely arranged compress by spring, so when temperature variation appearred in the medium of the Material valve of flowing through, the expansion of each component did not all influence the flexibility of its operation in the 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 closely with working surface between the valve seat, has improved the leakproofness of 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 Material valve long-time running still can be in sealing state.
