Base 1 is provided with multiple bolt hole 1a, is fastened by screw so that valve is integrally attached on the fixing object such as wall or cabinet, it is to avoid during valve switch, moment is transferred to flexible duct and causes the leakage of pipeline fatigue or interface leak.
Valve body 2 is provided with air inlet 2a, gas outlet 2b, detection mouth 2c, air inlet 2a adopts screw thread or fast-assembling interface to be connected with fuel gas transmission corrugated stainless steel tubing, gas outlet 2b adopts hickey and connects with corrugated stainless steel tubing with being connected, and detection mouth 2c adopts fast-assembling interface to be connected with pipeline leakage testing instrument U-tube manometer.
The spheroid 3 set in valve body 2 is provided with air inlet 3a, venthole 3b, detects hole 3c, detects mouth 2c with the air inlet 2a on valve body 2, gas outlet 2b respectively and connects, and drives spheroid 3 to rotate to realize pipeline by handle 4 and opens, closes and leakage detection function.
The diameter of air inlet (2a), gas outlet (2b) and detection mouth (2c) is respectively greater than the diameter of the air inlet (3a) of correspondence, venthole (3b) and detection hole (3c)；Diameter is horizontal channel diameter the 1/3～1/2 of detection hole (3c)；The axis angle of cut at 45 ° of detection hole (3c) axis and horizontal through hole.
The spheroid (3) of the present embodiment has initial closedown, detection and standard-sized sheet three file location；
As shown in Figure 4: under valve initial closed state, spheroid air inlet 3a and valve body air inlet 2a is that 90 degree of plumbness are airtight, spheroid venthole 3b and valve body gas outlet 2b is that 90 degree of plumbness are airtight, spheroid detection hole 3c and valve body detection mouth 2c is that 45 degree of angles are airtight, valve closes, and detects mouth self sealss.
As shown in Figure 5: under valve detection state, handle 4 is left-handed to pressure testing gear, spheroid air inlet 3a and valve body air inlet 2a is semi-connected state, spheroid venthole 3b and valve body gas outlet 2b is semi-connected state, spheroid detection hole 3c and valve body detection mouth 2c is full-mesh state, by U-tube manometer port to pipeline pressurising, judge whether whole pipeline leaks by the water column table situation of change of U-tube manometer.
As shown in Figure 6: valve wide open opens under state, 4 times pressure Rotate Lefts of handle are to opening gear, spheroid air inlet 3a and valve body air inlet 2a is full-mesh state, spheroid venthole 3b and valve body gas outlet 2b is full-mesh state, spheroid detection hole 3c and valve body detection mouth 2c is that 45 degree of angles are airtight, valve opening, whole piece pipeline is opened.
As shown in Figure 7: mouth 2c is on self sealing structure basis in detection, adopt secondary seal structure 2c1, and be made up of spring 2c1-1, hemisphere 2c1-2 and sealing ring 2c1-3 with protection device 2c2, self sealing structure 2c1；Spring 2c1-1 one end is fixed on detection mouth 2c inwall, and the other end is fixing with hemisphere 2c1-2 to be connected；It is cylindrical joint pin 2c1-6 on the left of hemisphere；Described cylindrical joint pin 2c1-6 is circumferentially with multiple through hole 2c1-4；When the state of detection, thimble withstands hemisphere and keeps three valve ports and corresponding valve opening all to keep connected state, sealing ring 2c1-3 to be installed in the detection mouth inwall circumferential recess outside hemisphere.
As shown in Figure 9: protect device 2c2 by protecting lid and sealing ring to form.Under pipeline unlatching, closure state; detection mouth 2c seals, and detection mouth is protected by protection device 2c2, to avoid the spheroid that foreign object backs down in self sealing structure 2c1 to cause pipeline leakage; foreign object collision causes detection mouth and leak detection tool interface leak, it is impossible to reach the function of pipeline leak detection.
The job step of the present invention is:
During gas pipeline leakage detection; turn on protection device 2c2 on detection mouth; the fast interface of U-tube manometer is plugged into detection mouth; in interface, thimble backs down the hemisphere 2c1-2 in self sealing structure 2c1; make the spacing place of installation in the cylindrical joint pin contact detection oral cavity body on the left of hemisphere 2c1-2; hemisphere 2c1-2 external diameter is less than detection Ti Nei footpath, oral cavity; the through hole 2c1-2a that hemisphere 2c1-2 bottom is provided with detects hole with ball body of valve and connects; toward pipeline pressurising, check that U-tube manometer water column changes to determine whether pipeline leaks；After leak detection, U-tube manometer fast interface departs from detection mouth 2c1, and screw on protection device 2c2.
Embodiment two
The present embodiment and embodiment one are different in that the end of the cylindrical joint pin 2c1-6 on the left of the hemisphere 2c1-2 of self sealing structure 2c1 additionally arranges pig tail catheter 2c1-5, as shown in Figure 8.Other structures are essentially identical.So, when carrying out Leak Detection when the fast interface of U-tube manometer and detection mouth being plugged into, in interface, thimble backs down in the process of the hemisphere 2c1-2 in self sealing structure 2c1, insertion is detected hole 3c by the pig tail catheter 2c1-5 of joint pin termination, guarantee the ideal position that spheroid 3 is under valve detection state, avoid due to reasons such as handle loosen that to cause that spheroid 3 rotates not in place, making air inlet 3a and valve body air inlet 2a, spheroid venthole 3b and valve body gas outlet 2b fail is semi-connected state, and the untrue situation of testing result caused occurs.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to replacement or the technical scheme of equivalent transformation formation, all fall within the protection domain of application claims.
