Description
Technical field
The invention belongs to pipeline valve technical field, be specifically related to a kind of heavy caliber inserting turning water delivery one-way valve.
Background technique
At present, the heavy caliber water delivery one-way valve of more than DN200 generally adopts Flange joint, Heavy Weight, and disassembly and assembly time is long, is contained on fixing waterline.And current remote is for above-water method, water drainage or drought resisting etc., what all adopt is the soft pipeline of movement, lays wartime temporarily, requires that one-way valve can quick mounting, lightweight, is convenient to manual operation.Traditional one-way valve is owing to adopting form of flanges, and Heavy Weight, needs erection more than 12 bolts during use, and thus existence dismounting intensity is large, expend time in problem that is long, that be manually difficult to movement, cannot meet the demand that mobile remote supplies water.
Water-carriage system is in operation for a certain reason, and when water pump shuts down suddenly, pump internal pressure disappears, and the high pressure water be connected with exit of pump will reverse flow waterback pump.When exit of pump is equipped with one-way valve, it can be closed immediately, prevents high pressure water reverse flow waterback pump.
Summary of the invention
Object of the present invention is exactly that a kind of structure designed for above-mentioned deficiency is simple, beautiful shape, dress, tear open convenient, lightweight heavy caliber inserting turning water delivery one-way valve, be mainly used in the impact preventing high pressure water from refluxing to water pump vane in waterline, rely on the automatic valve that pressure medium opens and closes.
Technical solution of the present invention is: a kind of heavy caliber inserting turning water delivery one-way valve, is characterized in that: comprise valve body, connecting body, valve plate, intermediate rotary shaft and torsion spring; Wherein, the two ends of valve body are connected with connecting body respectively by connecting body inner seal circle; Connecting body outer end is provided with end-face seal ring; Valve plate comprises two half identical valve plates, and torsion spring set is contained in intermediate rotary shaft, and intermediate rotary shaft is connected with two and half valve plates of valve plate respectively through hinge; The two ends of intermediate rotary shaft are fixed on valve body; The surrounding boss that body cavity is corresponding with valve plate and intermediate lands surface of contact are provided with valve plate seal ring.
Connecting body described in technical solution of the present invention and between valve body adopt be threaded, and by connecting body inner seal circle sealing.
Connecting body described in technical solution of the present invention and valve body adopt aluminum alloy material casting, lightweight, good corrosion resistance, and valve plate adopts aluminum bronze casting.
Connecting body described in technical solution of the present invention is the inserting turning connector interfaces of 12 pawls, can realize being connected fast, easy accessibility, highly versatile with other bigbore inserting turning hose coupling.
The present invention is owing to adopting by valve body, connecting body, valve plate, the heavy caliber inserting turning water delivery one-way valve that intermediate rotary shaft and torsion spring are formed, wherein, the two ends of valve body are connected with connecting body respectively by connecting body inner seal circle, connecting body outer end is provided with end-face seal ring, valve plate comprises two half identical valve plates, torsion spring set is contained in intermediate rotary shaft, intermediate rotary shaft is connected with two and half valve plates of valve plate respectively through hinge, the two ends of intermediate rotary shaft are fixed on valve body, the boss surface of contact that body cavity is corresponding with valve plate is provided with valve plate seal ring, thus when current are postive direction, valve plate is pressed on the boss of valve body by the effect of torsion spring, during use, under the pressure of water, two and half valve plates upwards rotate around intermediate rotary shaft, valve is opened automatically, when current are opposite direction, hydraulic pressure makes valve plate and valve body press tighter and tighter, and valve is closed automatically.The present invention has that junction structure is simple, beautiful shape, lightweight, flexible to operation, safe and reliable feature, and weight is only 1/6 of traditional one-way valve, a people and liftablely complete its loading and unloading.The present invention is mainly used in the impact that the soft pipeline of mobile remote water supply prevents high pressure water from refluxing to water pump vane, also can be used on other pipeline needing to connect fast.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, Figure 2, Figure 3, Figure 4.Heavy caliber inserting turning water delivery one-way valve of the present invention comprises connecting body 1, end-face seal ring 2, connecting body inner seal circle 3, valve body 4, valve plate 5, valve plate seal ring 6, intermediate rotary shaft 7 and torsion spring 8.Wherein, the two ends of valve body 4 are threaded with connecting body 1 respectively by connecting body inner seal circle 3.Connecting body 1 outer end is provided with end-face seal ring 2, seals when being convenient to be connected with hose coupling.Valve plate 5 comprises two identical semicircle half valve plates, 2 torsion springs 8 are sleeved in intermediate rotary shaft 7, two and half valve plates of valve plate 5 are connected with intermediate rotary shaft 7 through hinge respectively, one end of 2 torsion springs 8 is hung on stationary axle, the other end of 2 torsion springs 8 lays respectively on two and half valve plates of valve plate 5, the two ends of intermediate rotary shaft 7 and torsion spring stationary axle are all fixed on valve body 4, the surrounding boss 9 that valve body 4 inner chamber is corresponding with valve plate 5 and intermediate lands 10 surface of contact are provided with valve plate seal ring 6, under the pressure of aqueous medium, two and half valve plates of valve plate 5 upwards rotate around intermediate rotary shaft 7, valve is opened automatically.When current are opposite direction, hydraulic pressure makes valve plate 5 and valve body 4 press tighter and tighter, and valve is closed automatically.Connecting body 1 and valve body 4 adopt aluminum alloy material casting, lightweight, good corrosion resistance, and conventional flange one-way valve is generally Cast Steel, Heavy Weight.Valve plate 5 adopts aluminum bronze casting.Connecting body 1 is the inserting turning connector interfaces of 12 pawls, can realize being connected fast, easy accessibility, highly versatile with other bigbore inserting turning hose coupling.Because traditional one-way valve generally adopts Flange joint, need erection more than 12 bolts during use, labor intensity is large, and the time is long.By using inserting turning hose coupling form, can quick-detachment, thus greatly reduce the labor intensity of the installation of one-way valve, dismounting and maintenance, save the time.Valve body 4 outer wall is provided with handle, is convenient to carrying.
As shown in Figure 5, during installation, first valve plate 5, torsion spring 8 are fixed in intermediate rotary shaft 7, then entirety are fixed on valve body 4 by intermediate rotary shaft 7 two ends, finally torsion spring 8 is hung over the installation that namely torsion spring stationary axle completes valve plate.
Its main structure and working principle are: valve plate 5 and torsion spring 8 are separately fixed in intermediate rotary shaft, valve plate is dish-style bivalve structure, at ordinary times, on the surrounding boss 9 that valve plate 5 is pressed in valve body 4 by the effect of torsion spring 8 and intermediate lands 10, during use, under the pressure of water, promote left and right two clack valve plates 5 and upwards rotate around intermediate rotary shaft 7, valve is opened automatically.When current are opposite direction, hydraulic pressure makes valve plate 5 and valve body 4 press tighter and tighter, and valve is closed automatically.
