Handle 4 sets sphere 3 in valve body 2.
Pedestal 1 is equipped with multiple bolt hole 1a, is fastened by screw, so that valve is integrally attached to wall or cabinet etc. admittedly
On earnest part, avoids when valve switch torque from being transferred to flexible duct and pipeline fatigue is caused to leak or interface leak.
Valve body 2 is equipped with air inlet 2a, gas outlet 2b, detection mouth 2c, and air inlet 2a is using screw thread or fast-assembling interface and combustion
Gas conveying is connected with corrugated stainless steel tubing, and gas outlet 2b is connected using hickey and connection with corrugated stainless steel tubing, detection mouth
2c is connect using fast-assembling interface with pipeline leakage testing tool U-tube manometer.
The sphere 3 set in valve body 2 be equipped with air inlet 3a, venthole 3b, detection hole 3c, respectively with the air inlet on valve body 2
2a, gas outlet 2b detection mouth 2c connection drive the rotation of sphere 3 by handle 4 to realize pipeline unlatching, closure and leak detection function
Energy.
The diameter of air inlet (2a), gas outlet (2b) and detection mouth (2c) is respectively greater than corresponding air inlet (3a), outlet
The diameter in hole (3b) and detection hole (3c)；The diameter of detection hole (3c) is the 1/3~1/2 of horizontal channel diameter；Detection hole (3c)
The axis of the axis and horizontal through hole angle of cut at 45 °.
The sphere (3) of the present embodiment has initial closing, detection and three file location of standard-sized sheet；
As shown in Figure 4: under valve initial closed state, sphere air inlet 3a and valve body air inlet 2a are in 90 degree of plumbness
Closed, sphere venthole 3b and valve body gas outlet 2b are closed in 90 degree of plumbness, sphere detection hole 3c and valve body detection mouth 2c
It is closed in 45 degree of angles, valve closure, detection mouth self-sealing.
As shown in Figure 5: under valve detection state, handle 4 is left-handed to pressure testing gear, sphere air inlet 3a and valve body air inlet
2a is in semi-connected state, and sphere venthole 3b and valve body gas outlet 2b are in semi-connected state, sphere detection hole 3c and valve body detection
Mouth 2c is in full-mesh state, and from a port of U-tube manometer to pipeline pressurising, the water column table for passing through U-tube manometer changes feelings
Condition determines whether whole root canal road leaks.
As shown in Figure 6: valve wide open opens under state, and handle 4 pushes Rotate Left to opening gear, sphere air inlet 3a and
Valve body air inlet 2a is in full-mesh state, and sphere venthole 3b and valve body gas outlet 2b are in full-mesh state, sphere detection hole 3c
In 45 degree of angles, closed, valve opening, whole pipeline are opened with valve body detection mouth 2c.
As shown in Figure 7: detection mouth 2c is on the basis of self sealing structure, using secondary seal structure 2c1, and with protection dress
2c2 is set, self sealing structure 2c1 is made of spring 2c1-1, hemisphere 2c1-2 and sealing ring 2c1-3；The one end spring 2c1-1 is solid
It is scheduled on detection mouth 2c inner wall, the other end is fixedly connected with hemisphere 2c1-2；It is cylindrical connecting column 2c1-6 on the left of hemisphere；
The cylinder connecting column 2c1-6 is circumferentially with multiple through-hole 2c1-4；In detecting state, thimble withstands hemisphere holding
Three valve ports and corresponding valve opening keep connected state, and it is circumferential that sealing ring 2c1-3 is installed on the detection mouth inner wall on the outside of hemisphere
In groove.
As shown in Figure 9: protective device 2c2 is made of protection cap and sealing ring.Pipeline is opened, under closed state, detection mouth
2c sealing, protective device 2c2 protect detection mouth, and opening the sphere in self sealing structure 2c1 to avoid foreign object leads to pipe
Road leakage, foreign object collision lead to detection mouth and leak detection tool interface leak, are unable to reach the function of pipeline leak detection.
Work step of the invention are as follows:
When gas pipeline leakage detects, protective device 2c2 in detection mouth is unscrewed, by the fast interface of U-tube manometer and inspection
It surveys mouth to plug into, thimble opens the hemisphere 2c1-2 in self sealing structure 2c1 in interface, so that the cylinder on the left of hemisphere 2c1-2
Shape connecting column contacts the intracorporal installation spacing place of detection mouth chamber, and hemisphere 2c1-2 outer diameter is less than detection mouth cavity internal diameter, hemisphere
The through-hole 2c1-2a that the lower part 2c1-2 is equipped with is connected to ball body of valve detection hole, toward pipeline pressurising, checks that U-tube manometer water column becomes
Change to determine whether pipeline leaks；After leak detection, U-tube manometer fast interface and detection mouth 2c1 are detached from, and screw on protective device
2c2。
Embodiment two
The present embodiment and embodiment one are the difference is that cylinder on the left of the hemisphere 2c1-2 of self sealing structure 2c1
In addition pig tail catheter 2c1-5 is arranged in the end of shape connecting column 2c1-6, as shown in Figure 8.Other structures are essentially identical.It will in this way, working as
The fast interface of U-tube manometer and detection mouth are plugged into when carrying out leak detection, and thimble opens in self sealing structure 2c1 in interface
During hemisphere 2c1-2, the pig tail catheter 2c1-5 of connecting column end will be inserted into detection hole 3c, it is ensured that sphere 3 is in valve
Ideal position under detecting state, avoids that cause sphere 3 to rotate not in place due to loosening etc. handle, makes air inlet 3a and valve
Body air inlet 2a, sphere venthole 3b and valve body gas outlet 2b fail in semi-connected state, the caused untrue feelings of testing result
Condition occurs.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
