Description
Technical field
The invention belongs to pipeline valve technical fields, and in particular to a kind of heavy caliber inserting turning water delivery check valve.
Background technique
Currently, the heavy caliber water delivery check valve of DN200 or more generally uses flanged joint, weight weight, disassembly and assembly time is long, dress
On fixed waterline.And current remote is for above-water method, water drainage or drought resisting etc., all using mobile soft pipeline,
Wartime is temporarily laid with, it is desirable that check valve can Fast Installation, it is light-weight, be convenient for manual operation.Traditional check valve is due to using
Form of flanges, weight weight, when use, need to temporarily fasten 12 or more bolts, thus have that disassembly intensity is big, consuming time is long, people
Work is difficult to mobile problem, is unable to satisfy the demand of mobile remote water supply.
In operation for some reason, when water pump shuts down suddenly, pump pressure disappears water-carriage system, pumps out with water
The connected high pressure water of mouth will reverse flow back water pump.When exit of pump is equipped with check valve, it can be closed immediately, prevent high pressure water
Reverse flow back water pump.
Summary of the invention
A kind of structure designed the purpose of the present invention is to above-mentioned shortcoming is simple, and good appearance is filled, torn open just
Victory, light-weight heavy caliber inserting turning water delivery check valve are mainly used for preventing high pressure water reflux to water pump vane in waterline
Impact, by pressure medium open and close automatic valve.
The technical solution of the invention is as follows: a kind of heavy caliber inserting turning water delivery check valve, it is characterised in that: including valve
Body, connector, valve plate, intermediate rotary shaft and torsional spring；Wherein, the both ends of valve body pass through connector inner seal circle and connector respectively
Connection；Connector outer end is equipped with end-face seal ring；Valve plate includes two identical half valve plates, and torsion spring set is mounted in intermediate rotary shaft,
Intermediate rotary shaft is connect with two and half valve plates of valve plate respectively through hinge；The both ends of intermediate rotary shaft are fixed on valve body；Body cavity
Surrounding boss corresponding with valve plate and intermediate lands contact surface are equipped with valve plate sealing ring.
Using threaded connection between connector and valve body described in technical solution of the invention, and pass through connector
The sealing of inner seal circle.
Connector described in technical solution of the invention and valve body use aluminum alloy material casting and forming, weight
Gently, good corrosion resistance, valve plate use aluminium bronze casting and forming.
Connector described in technical solution of the invention is the inserting turning connector interfaces of 12 pawls, with other big mouths
The inserting turning hose coupling of diameter is able to achieve quick connection, convenient for disassembly and assembly, versatile.
The present invention is due to using the heavy caliber inserting turning water delivery being made of valve body, connector, valve plate, intermediate rotary shaft and torsional spring
Check valve, wherein the both ends of valve body pass through connector inner seal circle respectively and connect with connector, and connector outer end is equipped with end face
Sealing ring, valve plate include two identical half valve plates, torsion spring set in the intermediate rotary shaft, intermediate rotary shaft through hinge respectively with valve plate
Two and half valve plates connection, the both ends of intermediate rotary shaft are fixed on valve body, on body cavity boss contact surface corresponding with valve plate
Equipped with valve plate sealing ring, thus when water flow is positive direction, valve plate is pressed on the boss of valve body by the effect of torsional spring, in use,
Under the pressure of water, two and half valve plates are rotated up around intermediate rotary shaft, and valve automatically turns on；When water flow is opposite direction, hydraulic pressure
Valve plate and valve body is set the more to press the more tight, valve is automatically closed.The present invention simple, good appearance, light-weight, operation side with junction structure
Just flexible, safe and reliable feature, weight are only the 1/6 of traditional check valve, its loader of a people, that is, liftable completion
Make.Impact of the high pressure water reflux to water pump vane is prevented on the soft pipeline to supply water present invention is mainly used for mobile remote,
It can be used on other pipelines that need to quickly connect.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3, Figure 4.Heavy caliber inserting turning water delivery check valve of the present invention includes that connector 1, end face are close
Seal 2, connector inner seal circle 3, valve body 4, valve plate 5, valve plate sealing ring 6, intermediate rotary shaft 7 and torsional spring 8.Wherein, valve body 4
Both ends pass through connector inner seal circle 3 respectively and are threadedly coupled with connector 1.1 outer end of connector is equipped with end-face seal ring 2, just
Sealing when being connect with hose coupling.Valve plate 5 includes two identical semicircle half valve plates, and 2 torsional springs 8 are sleeved on intermediate rotary shaft
On 7, two and half valve plates of valve plate 5 are connect through hinge with intermediate rotary shaft 7 respectively, and one end of 2 torsional springs 8 is hung in fixing axle
On, the other end of 2 torsional springs 8 is located on two and half valve plates of valve plate 5, and the both ends of intermediate rotary shaft 7 and torsion spring fixed shaft are equal
It is fixed on valve body 4,4 inner cavity of valve body surrounding boss 9 corresponding with valve plate 5 and 10 contact surface of intermediate lands are sealed equipped with valve plate
Circle 6, under the pressure of aqueous medium, two and half valve plates of valve plate 5 are rotated up around intermediate rotary shaft 7, and valve automatically turns on.Work as water flow
When for opposite direction, hydraulic pressure makes valve plate 5 and valve body 4 the more press the more tight, and valve is automatically closed.Connector 1 and valve body 4 use aluminium alloy material
Matter casting and forming, light-weight, good corrosion resistance, conventional flange check valve are generally steel-casting, weight weight.Valve plate 5 is green using aluminium
Copper casting and forming.Connector 1 is the inserting turning connector interfaces of 12 pawls, is able to achieve with other bigbore inserting turning hose couplings
Quickly connection, it is convenient for disassembly and assembly, it is versatile.Since traditional check valve generally uses flanged joint, when use, need to temporarily fasten 12
A above bolt, large labor intensity, time are long.It by using inserting turning hose coupling form, can be quickly disassembled, thus significantly
The installation for reducing check valve, disassembly and maintenance labor intensity, save the time.4 outer wall of valve body is equipped with handle, is convenient for
It carries.
As shown in figure 5, first valve plate 5, torsional spring 8 are fixed in intermediate rotary shaft 7 when installation, it then will be entirely through centre
7 both ends of shaft are fixed on valve body 4, and torsional spring 8 is finally hung over the installation that torsion spring fixed shaft completes valve plate.
Its primary structure and working principle are: valve plate 5 and torsional spring 8 are separately fixed in intermediate rotary shaft, and valve plate is that dish-style is double
Valve plate 5 is pressed on the surrounding boss 9 and intermediate lands 10 of valve body 4 by valve structure, usually, the effect of torsional spring 8, in use, in water
Pressure under, push left and right two clack valve plates 5 be rotated up around intermediate rotary shaft 7, valve automatically turn on.When water flow is opposite direction,
Hydraulic pressure makes valve plate 5 and valve body 4 the more press the more tight, and valve is automatically closed.
