Description
Technical field
The utility model relates to the valve class, particularly a kind of novel buffer valve.
Background technique
Buffer valve is claimed check valve again, and its effect is to prevent that the medium in the pipeline from flowing backwards.
At present, existing a kind of buffer valve includes valve body; Valve body is provided with medium runner, also is provided with piston cavity on the valve body, is provided with piston, piston rod in the piston cavity; Be provided with the valve plate that is used for the conducting of control media runner, ends in the medium runner, valve plate forms hard sealing between valve plate and the medium runner inwall in running shaft is arranged on medium runner; Piston rod one end is connected with piston; The other end extends in the medium runner hinged with valve plate, and the upper and lower motion of piston rod drives the valve plate rotation, so realize medium runner conducting, end.
But the buffer valve of this structure is when piston rod drives the valve plate rotation; Sometimes because driving force is excessive; Valve plate and the collision of medium runner inwall can produce noise, also destroy the hard sealing between valve plate and the medium runner inwall easily, thereby influence the sealability of buffer valve.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology; The utility model provides a kind of novel buffer valve; Can slowly open or close valve plate, both avoid the collision of valve plate and medium runner inwall to produce noise, can guarantee the sealability of buffer valve again.
The technological scheme of the utility model: a kind of novel buffer valve, include valve body, valve body is provided with medium runner; Also be provided with piston cavity on the valve body, be provided with piston, piston rod in the piston cavity, be provided with the valve plate that is used for the conducting of control media runner, ends in the medium runner; Valve plate is in running shaft is arranged on medium runner; Piston rod one end extends in the medium runner and is linked with valve plate, also includes at least two damping devices, and described each damping device has included lubricating cup, one-way throttle valve; Described lubricating cup all with the piston cavity conducting; Described one-way throttle valve is arranged between lubricating cup and the piston cavity, and described piston cavity is provided with the connecting port that is communicated with lubricating cup, and the connecting port of described piston cavity is provided with up and down along described piston motion direction.
Adopt technique scheme; Described damping device can be so that described piston rod rotates at the control valve plate; And then with described medium runner conducting, when ending; Can be not excessive because of driving force, make the collision of valve plate and medium runner inwall produce noise, can guarantee the sealability of buffer valve again.
The further setting of the utility model: described damping device is provided with two, and described lubricating cup opening is provided with down, and described damping device also includes pipeline, and described lubricating cup is communicated with the connecting port of piston cavity through pipeline.
Adopt above-mentioned further setting, two damping devices can satisfy the needs of valve plate buffering, make simple in structurely, and cost reduces; The lubricating cup opening is provided with down, can make things convenient for fluid to get in the piston cavity, is convenient to the circulation of fluid; Described lubricating cup is communicated with the connecting port of piston cavity through pipeline, like this can be so that the cushioning effect of valve plate is better.
Further being provided with again of the utility model: described valve plate is obliquely installed in medium runner, the described medium runner convexity that extended internally, and described valve plate and described convexes to form hard sealing.
Adopt above-mentionedly further to be provided with, valve plate is obliquely installed, and can make things convenient for piston rod to drive the valve plate rotation again, and the convexity of extending in the medium runner can make things convenient for sealing firmly between medium runner inwall and the valve plate.
