Description
Technical field
The utility model relates to a kind of check-valves, specifically with the anti-rotation type lift check valve of quck-opening valve lid.
Background technology
The flap of lift check valve is positioned on valve body upper valve base sealing surface, and fluid pressure makes flap lift from sealing surface of seat, and medium back flow causes flap to fall back on valve seat, and cuts off flowing.Lift check valve is mainly made up of valve body, flap and valve gap at present.During following current, fluid enters valve from the import of lift check valve, and fluid is stopped by sagging flap, and the flow velocity of fluid reduces, and part dynamic pressure changes into hydrostatic pressure on flap, makes flap increase and opens；Time countercurrently, fluid enters valve from the outlet return of lift check valve, and the hydrostatic pressure of fluid, on the flap opened, makes flap decline and closes, and flap stops fluid backflow.
Existing lift check valve there is the problem that
(1) valve rod driving flap lifting is that lifting sliding is arranged in guide pin bushing, but, meanwhile, this valve rod can also rotate in guide pin bushing, in flap opening-closing process, by under the spiral-flow impact of fluid, this flap can rotate on valve seat, long-time after, flap serious wear can be caused, and then cause the sealing of flap to decline, reduce service life.
(2) lift check valve is the most unadjustable at flap unlatching pressure, it is impossible to meet the needs of reality application.
(3) valve gap of existing lift check valve typically all flange and bolt are connected on valve body, and this mode, in the opening procedure of valve gap, needs the instruments such as spanner just can open, and inconvenience is safeguarded in dismounting.
Summary of the invention
The purpose of this utility model is the shortcoming and defect in order to overcome prior art to exist, and provides a kind of reasonable in design, and can effectively prevent flap from rotating, and the anti-rotation type lift check valve with quck-opening valve lid of valve gap conveniently opening and closing.
nullFor achieving the above object，The technical solution of the utility model is to include valve body、Flap and valve gap，Import valve pocket and outlet valve pocket it is provided with in described valve body，It is provided with valve seat between this import valve pocket and outlet valve pocket，It is provided with in valve seat and import valve pocket and the valve base channel of outlet valve pocket，The flap cooperated with valve seat it is provided with in described valve body，The upper end of described flap is fixedly installed longitudinal valve rod，The guide pin bushing adaptive with the upper end straight skidding of valve rod it is provided with inside described valve gap，It is characterized in that: described valve gap and one end of valve body are hinged，The other end of valve gap and valve body is provided with fast opening and closing mechanism，Described fast opening and closing mechanism includes the hook being arranged on valve gap sidewall and is fixed on the locking seat on the sidewall of valve body upper end，Hinged on this locking seat it is provided with handle，Described handle is buckled at the hinged hook that is provided with of avris of the pin joint of locking seat relative to it，Described hook button is fixedly connected with hook mounting and coordinates，The sidepiece fixed lobe of described valve rod is provided with guiding flange，The longitudinal guide groove spacing with this guiding flange straight skidding circumference is set on the inwall of described guide pin bushing，The upper end of described flap is fixedly installed longitudinally guiding post relative to the avris of flap，The longitudinally guiding hole adaptive with described longitudinally guiding post straight skidding it is provided with inside described valve gap.
By this setting, utilize and guide flange and the longitudinally guiding positioning action of longitudinally guiding post, can effectively prevent the rotation of valve rod, it is thus possible to reduce the wear problem that flap brings because it rotates, and this setting further increases the steering capability of valve rod straight skidding so that the keying of flap is smooth and easy flexibly.It addition, by the fast opening and closing mechanism of this setting, when valve gap is opened by needs, it is only necessary to open fast opening and closing mechanism, then opened by valve gap, conveniently opening and closing is flexible.
The valve gap removable seal being described is set further and is fixed on above the upper end of valve body, also include pretightning force regulation spring and lower spring cup, the lower end of described lower spring cup has been wholely set screw shaft, the tapped blind hole threadeded with screw shaft is offered on the upper surface of described valve rod, described pretightning force regulation spring is arranged in guide pin bushing, and the two ends of this pretightning force regulation spring act on respectively and being connected on valve gap and lower spring cup.
By this setting, when needing the unlatching pressure of flap is adjusted, have only to valve gap, and by rotating the screw shaft of lower spring cup, just can change the fixed position relative of lower spring cup and valve rod, so that the collapsing length of prefastening force spring is adjusted, realize flap is opened the regulation of pressure the most easily.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
