Description
[technical field]
The present invention relates to a kind of flap, particularly a kind of wear-resisting flap technical field.
[background technique]
Existing common valve, some can be used for being switched on or switched off of control piping system, but because some pipe-line system such as underground gas gathers pipe-line system, in the gatherer process of underground gas, often there are the hard solid particle polluters such as silt to be mixed in the gas of circulation, when valve is unlocked, because pipe-line system itself all exists certain pressure medium, therefore under the effect of pressure medium, these impurity can form high speed circulation discharge in valve, thus serious erosive wear is caused to such as the flap etc. of the structure in valve, substantially reduce the working life of flap and whole device.
[summary of the invention]
Object of the present invention solves existing issue exactly, the valve mechanism that a kind of flap is more wear-resisting is provided, internal diameter due to described Sealing offset hole and valve seat offset hole is also less than the internal diameter of valve body media outlet passage, therefore medium at this moment can accelerate the flow velocity of water, thus be conducive to impurity and discharge fast, described flap Sealing and valve seat can preferably adopt as the high-abrasive materials such as cemented carbide or pottery are made, and improve the erosive wear resistant performance of valve further.
For achieving the above object, the present invention proposes the valve mechanism that a kind of flap is more wear-resisting, comprise valve body, flap, valve seat and valve rod, described valve body is provided with medium entrance passage and media outlet channel, described valve seat is loaded in valve body and correspondence is positioned near valve body media outlet passage here, described flap is loaded on valve seat, described valve rod is located in valve body and is fixed with flap, valve rod passes on the outer end outside valve body and driving mechanism is housed, described valve rod is coaxial with valve seat, the media outlet channel of valve body is coaxial with valve seat offset hole, described valve seat is fixed on valve body by locating stud.
As preferably, between described valve rod and flap, be provided with the Compress Spring for flap being pressed to valve seat.
As preferably, between described flap and valve seat, be provided with flap Sealing, and described flap Sealing and flap are fixed.
As preferably, described flap Sealing is provided with the Sealing offset hole of axially through flap Sealing, described valve seat is provided with the valve seat offset hole of axially through valve seat, and the internal diameter of described Sealing offset hole and valve seat offset hole is all less than the internal diameter of media outlet channel and medium entrance passage on valve body.
As preferably, between described valve seat outer peripheral surface and valve body and between flap Sealing outer peripheral surface and valve body, be equipped with seal ring.
Beneficial effect of the present invention: the valve mechanism that a kind of flap of the present invention is more wear-resisting, the flow velocity of water can be accelerated, thus be conducive to impurity and discharge fast, described flap Sealing and valve seat can preferably adopt as the high-abrasive materials such as cemented carbide or pottery are made, and improve the erosive wear resistant performance of valve further.
Feature of the present invention and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the valve mechanism that a kind of flap of the present invention is more wear-resisting;
In figure: 1-valve body, 2-flap, 3-valve seat, 4-valve rod, 5-driving mechanism, 6-Compress Spring, 7-flap Sealing, 8-locating stud, 9-seal ring, 11-medium entrance passage, 12-media outlet channel, 31-valve seat offset hole, 71-Sealing offset hole.
[embodiment]
Consult Fig. 1, the valve mechanism that a kind of flap of the present invention is more wear-resisting, comprise valve body 1, flap 2, valve seat 3 and valve rod 4, described valve body 1 is provided with medium entrance passage 11 and media outlet channel 12, described valve seat 3 is loaded in valve body 1 and correspondence is positioned near valve body media outlet passage 12 here, described flap 2 is loaded on valve seat 3, described valve rod 4 is located in valve body 1 and is fixed with flap 2, valve rod 4 passes on the outer end outside valve body 1 and driving mechanism 5 is housed, described valve rod 4 is coaxial with valve seat 3, the media outlet channel 12 of valve body 1 is coaxial with valve seat 3 offset hole, described valve seat 3 is fixed on valve body 1 by locating stud 8, the Compress Spring 6 for flap 2 being pressed to valve seat 3 is provided with between described valve rod 4 and flap 2, flap Sealing 7 is provided with between described flap 2 and valve seat 3, and described flap Sealing 7 is fixed with flap 2, described flap Sealing 7 is provided with the Sealing offset hole 71 of axially through flap Sealing 7, described valve seat 3 is provided with the valve seat offset hole 31 of axially through valve seat 3, the internal diameter of described Sealing offset hole 71 and valve seat offset hole 31 is all less than the internal diameter of media outlet channel 12 and medium entrance passage 11 on valve body 1, seal ring 9 is equipped with between described valve seat 3 outer peripheral surface and valve body 1 and between flap Sealing 7 outer peripheral surface and valve body 1.
The valve mechanism that a kind of flap of the present invention is more wear-resisting, the medium entered due to medium entrance passage 11 on valve body 1 is discharged to media outlet channel 12 through Sealing offset hole 71 and valve seat offset hole 31, and the internal diameter of described Sealing offset hole 71 and valve seat offset hole 31 is all less than the internal diameter of medium entrance passage 11 on valve body 1, therefore when valve is in full open state, on valve body 1 in medium entrance passage 11 circulation area of medium by the circulation area much larger than medium in Sealing offset hole 71 and valve seat offset hole 31, thus greatly slow down medium enter valve body 1 and in valve body media inlet passage 11 circulation speed, and then the erosive wear power effectively weakened to each parts of valve when medium enters valve body 1, impurity is after Sealing offset hole 71 and valve seat offset hole 31, internal diameter due to described Sealing offset hole 71 and valve seat offset hole 31 is also less than the internal diameter of valve body media outlet passage 12, therefore medium at this moment can accelerate flow velocity, thus is conducive to impurity and discharges fast.It is the erosive wear resistant performance improving valve further simultaneously, described flap Sealing 7 and valve seat 3 can preferably adopt as the high-abrasive materials such as cemented carbide or pottery are made, the flow velocity of water can be accelerated, thus be conducive to impurity and discharge fast, described flap Sealing and valve seat can preferably adopt as the high-abrasive materials such as cemented carbide or pottery are made, and improve the erosive wear resistant performance of valve further.
