Fig. 1 is anti-vacuum gas discharge valve structural schematic diagram, and Fig. 2 is exhauster structure schematic diagram.
Wherein: 1 is valve body, and 2 be lower guide sleeve, and 3 be flap, and 4 be spring, and 5 be valve seat, and 6 be valve bonnet, and 7 be exhaust apparatus,
71 be non-return flap, and 72 be exhaust seat, and 73 be sheet metal, and 74 be exhaust clack, and 75 be floating ball.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of anti-vacuum evacuation valve arrangement, includes valve body 1, lower guide sleeve 2, flap 3, spring 4, valve seat
5, valve bonnet 6, exhaust apparatus 7；The valve body 1 is the flanged (FLGD) hollow sphere valve body structure in both ends, is welded in the middle part of the valve body 1
It is connected with lower guide sleeve 2；The lower guide sleeve 2 is a horizontal girder construction in valve body, which is provided centrally with circle
Hole, and flap 3 is installed in circular hole；The flap 3 is cylindrical structure, is provided with a circle disk evagination, and valve at the top of the flap 3
Spring 4 is welded and connected between valve 3 and lower guide sleeve 2；Valve seat 5 is connected with by flange bolt at the top of the valve body 1, the valve seat
5 be hollow disc structure, and the valve port for fitting in 1 port inner wall of valve body is provided in the middle part of valve seat 5, is provided with under in the middle part of valve port
The parallel crossbeam of guide sleeve 2 is provided with the circular hole passed through for flap 3 on crossbeam；5 top surface of valve seat is welded and connected with valve bonnet 6,
The valve bonnet 6 is by two vertical supports and awning structure composition；The side in valve port of flap 3 is provided with exhaust apparatus 7, the exhaust
Device 7 is made of non-return flap 71, exhaust seat 72, sheet metal 73, exhaust clack 74 and floating ball 75；The flap 3 is on valve port side
It is provided with a T shape circular hole, is provided with crossbeam with holes in the middle part of circular hole, upside-down mounting has 71 structure of inverted T-shaped conical surface non-return flap in crossbeam hole；Institute
It states T shape circular hole bottom end and is welded and connected with T shape hollow air discharge seat 72, and 72 side of exhaust seat is welded and connected with L shape sheet metal 73；Institute
It states 73 one end of sheet metal to be welded on exhaust seat 72,73 top surface of sheet metal corresponds to and is arranged with exhaust clack 74 at 72 hole of exhaust seat, gold
Belong to 73 other end of piece and is welded with floating ball 75.
When it is implemented, the floating ball 75 is interior hollow ball structure.
When practical operation, anti-vacuum gas discharge valve is connected by the flange of 1 lower end of valve body with fluid pipeline or pressure vessel,
5 inner cavity of valve seat of valve upper end is communicated with atmosphere, and the pressure value that flap 3 is opened is presetting by spring 4.When fluid pipeline or pressure
When occurring negative pressure in force container, and reaching presetting value, flap 3 moves down under atmospheric pressure, valve opening.This
When, the air in atmosphere enters in pipeline or pressure vessel, prevents pipeline or pressure vessel compressive strain or damage.When pipeline or
When pressure medium in pressure vessel is restored to safety value, flap 3 moves up under the action of 4 power of spring, and valve is closed.
When valve is for pumping the operating conditions such as front-end pipelines, need first to empty the sky in pipeline by exhaust apparatus 7 in turn on pump
Gas.When 1 inner cavity of valve body is full of air, air can be discharged in atmosphere by the venthole on flap 3.With air in pipeline
It reduces, the liquid mediums such as water enter 1 inner cavity of valve body, and floating ball 75 slowly rises under the buoyancy of liquid, and drives gold
Belong to piece 73 and exhaust clack 74 slowly rises.When the medium of 1 inner cavity of valve body is close to when emptying, exhaust clack 74 and exhaust seat 72 are sealed
Face forms sealing, and the liquid mediums such as water is prevented to be discharged into atmosphere by venthole.
For valve under the state that is not turned on, medium enters fluid pipeline or pressure vessel by venthole in order to prevent
In, in the upper end of venthole, design has non-return flap 71, to guarantee that venthole has the function of unidirectionally discharging to atmospheric side.
