It is provided with connecting rod, the bottom of the connecting rod is provided with semisphere valve, and the bottom of the semisphere valve is provided with tension spring two, the drawing
The bottom of spring two is provided with round valve, and the bottom of the valve chest is socketed with first pipe, the bottom socket of the first pipe
There are second pipe, the top edge of the semisphere valve to be bonded with the bottom of valve chest, the top edge and second of the circle valve
The bottom of pipeline is bonded, and is provided with water inlet on the left of the valve chest, the bottom of the second pipe is provided with water outlet.
Preferably, the top edge of the round valve is provided with the sealing ring to match with first pipe bottom, and seals
The inside height of circle is less than the height in outside.
Preferably, the diameter of the semisphere valve is more than the diameter in valve chest bottom cross section, and the circle valve diameter is more than
The diameter in first pipe cross section.
Preferably, the diameter in the cross section of the first pipe is more than the diameter in the cross section of valve chest, second pipe
The diameter in road cross section is more than the diameter in first pipe cross section.
Preferably, the inner wall of the valve chest, first pipe and second pipe is painted with poly- charcoal erosion resistant coating.
Compared with prior art, the beneficial effects of the invention are as follows：Prevent medium from flowing backwards by semisphere valve and round valve,
When semisphere valve uses surface corrosion because of long-time, round valve can still prevent medium from flowing backwards, and on the whole, double valves can
Ensure that the device can be for a long time using being not in the phenomenon that medium is flow backwards, leakproofness is stronger.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：The round valve of 1 valve chest, 2 tension springs one, 3 pistons, 4 connecting rods, 5 semisphere valves, 6 tension spring two, 7,8 first pipes,
9 second pipes, 10 water inlets, 11 water outlets.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：A kind of forged steel check valve receptacle component, including valve chest 1,
The inside top of valve chest 1 is provided with tension spring 2, and the bottom of tension spring 2 is connected with piston 3, and the bottom centre of piston 3 is provided with connection
The bottom of bar 4, connecting rod 4 is provided with semisphere valve 5, and the bottom of semisphere valve 5 is provided with tension spring 26, and the bottom of tension spring 26 is provided with
The bottom of round valve 7, valve chest 1 is socketed with first pipe 8, and the bottom of first pipe 8 is socketed with second pipe 9, semisphere valve 5
Top edge is bonded with the bottom of valve chest 1, and the top edge of round valve 7 is bonded with the bottom of second pipe 9, valve chest 1
Left side is provided with water inlet 10, and the bottom of second pipe 9 is provided with water outlet 11.
Wherein, the top edge of round valve 7 is provided with the sealing ring to match with 8 bottom of first pipe, and sealing ring
Inside height is less than the height in outside, and when 8 bottom of first pipe uses corrosion because of long-time, sealing ring can will still generate
Gap be sealed；
The diameter of semisphere valve 5 is more than the diameter in 1 bottom cross section of valve chest, and 7 diameter of round valve is more than 8 cross section of first pipe
Diameter, when the surface corrosion of semisphere valve 5, semisphere valve 5 can still be played the role of sealing upwards by the pulling force of tension spring 1；
The diameter in the cross section of first pipe 8 is more than the diameter in the cross section of valve chest 1, and the diameter in 9 cross section of second pipe is big
Diameter in 8 cross section of first pipe, semisphere valve 5 and round valve 7 when opened medium from first pipe 8 and second pipe 9
It falls；
The inner wall of valve chest 1, first pipe 8 and second pipe 9 is painted with poly- charcoal erosion resistant coating, prevents valve chest 1, first pipe
8 and second pipe 9 inner wall corrosion, increase the service life of check-valves.
Operation principle：When medium is from water inlet 10 into fashionable, semisphere valve 5, which is under pressure, pulls connecting rod 4, and connecting rod 4 is drawn
Piston 3, piston 3 pull tension spring 1, and semisphere valve 5 is moved downward generates channel with the bottom of valve chest 1, and medium enters, round
7 stress of valve pulls tension spring 26, and round valve 7 is moved downward generates channel, flow of media, when water inlet stops with 9 bottom of second pipe
Only medium into fashionable, when tension spring 1 and tension spring 26 do not receive pulling force, semisphere valve 5 is bonded with the bottom of valve chest 1, round
Valve 7 is bonded with 8 bottom of first pipe prevents medium from flowing backwards, while the bottom of round valve 7 receives the power of medium back flow, makes round valve
7 are bonded with 8 bottom of first pipe, while pushing semisphere valve 5 to be bonded with 1 bottom of valve chest by tension spring 26, make its leakproofness more
It is good.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
