Compared with prior art, the utility model has the beneficial effects that preventing medium from falling by semisphere valve and round valve
Stream, when semisphere valve uses surface corrosion because of long-time, round valve can still prevent medium from flowing backwards, on the whole, dual valve
Door can guarantee that the device can be for a long time using being not in the phenomenon that medium is flow backwards, and leakproofness is stronger.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
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 embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of forged steel check valve receptacle component, including valve casing
Body 1, the inside top of valve chest 1 are 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
Connecting rod 4, the bottom of connecting rod 4 are 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 set
It is equipped with round valve 7, the bottom of valve chest 1 is socketed with first pipe 8, and the bottom of first pipe 8 is socketed with second pipe 9, hemisphere
The top edge of valve 5 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 casing
The left side of body 1 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 be generated
Gap be sealed；
The diameter of semisphere valve 5 is greater than the diameter in 1 bottom cross section of valve chest, and it is crosscutting that round 7 diameter of valve is greater than first pipe 8
The diameter in face, when the surface corrosion of semisphere valve 5, semisphere valve 5 can still be played the work of sealing by the pulling force of tension spring 1 upwards
With；
The diameter in the cross section of first pipe 8 be greater than valve chest 1 cross section diameter, 9 cross section of second pipe it is straight
Diameter is greater than the diameter in 8 cross section of first pipe, and medium is managed from first pipe 8 and second when opened for semisphere valve 5 and round valve 7
Road 9 is fallen；
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
The inner wall corrosion of pipeline 8 and second pipe 9 increases the service life of check-valves.
Working principle: when medium enters from water inlet 10, 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, which 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, which is moved downward, generates channel, flow of media, when water inlet stops with 9 bottom of second pipe
Only when the entrance of medium, 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.
