Limitation.
Describe check valve of the present utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figure 1, a kind of check valve, including the valve body with hollow channel, the valve body are arranged to including one end
First valve body 1 of inlet 3 and the second valve body 2 connected with the first valve body 1, first valve body 1 is interior to set core assembly, bag
Valve rod 6, the spring being set on valve rod 7 and bottom 8 are included, the insertion of bottom 8 is arranged on the other end of first valve body 1,
Through hole is set to form refluxing opening 5 on the bottom 1, one end and the valve rod 6 of the spring 7 are supported, and the other end is supported with bottom 8；
When cooperation is supported in one end of the valve rod 6 with the inlet 3, the hollow channel of the inlet 3 and first valve body 1 seals
Close, the refluxing opening 5 connects with the hollow channel of first valve body 1；The other end of the valve rod 6 is supported with the bottom 8
During cooperation, the hollow channel of the refluxing opening 5 and first valve body 1 is closed, the inlet 3 and first valve body 1
Hollow channel is connected, and second valve body 2 is arranged between the inlet 3 and the refluxing opening 5, and the valve rod 6 is first
Moved between the inlet 3 and refluxing opening 5 of the hollow channel of valve body 1, realize the envelope of the hollow channel of 3 and first valve body of inlet 1
Close and connect, the connection and closing of the hollow channel of 5 and first valve body of refluxing opening 1, when realizing 3 feed liquor of inlet, liquid is from going out liquid
Mouth 4 flows away, and when inlet 3 stops feed liquor, liquid outlet 4 stops trickle immediately, and liquid flows away from refluxing opening 5, response speed
It hurry up.The check valve with refluxing opening 5 provided according to embodiment of the present utility model, when the inlet 3 of check valve does not have liquid
Enter fashionable, spring 7 is in compressive state, and valve rod 6 is supported in the position of inlet 3, the hollow channel of the valve body 1 of inlet 3 and first
Closing, refluxing opening 5 connect with the hollow channel of the first valve body 1；When the inlet 3 of check valve has liquid flow fashionable, liquid overcomes
The spring force top valve opening bar 6 of spring 7, valve rod 6 move to the direction of refluxing opening 5 under spring force, support bottom 8, backflow
The hollow channel of the valve body 1 of mouth 5 and first is closed, and inlet 3 connects with the hollow channel of the first valve body 1, and liquid flows from inlet 3
Enter the hollow channel of the first valve body 1, the second valve body 2 is arranged between the inlet 3 and the refluxing opening 5, into the first valve
The liquid of the hollow channel of body 1 flows away from liquid outlet 4；When inlet 3 stop feed liquor when, valve rod 6 under spring force to
The direction of inlet 3 is moved, and valve rod 6 supports cooperation, the hollow channel sealing of the valve body 1 of inlet 3 and first, backflow with inlet 3
