Advantage of the present utility model is: 1. owing to insert reduction valve dexterously in the blast tube of connector, it not only has pressure-reducing function, but also has the critical function of anti-decompression gas leakage, makes connector have more Security.2. thoroughly change the connector of in the past always the continuing to use structure that is connected with reduction valve, thereby simplified Connection Step, made things convenient for operation.
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
By following embodiment the utility model is further elaborated.
Referring to Fig. 1, shown in Figure 2, the gas safe connector of a kind of belt switch of embodiment of the utility model, anti-decompression gas leakage, include the steel cylinder pad 1, plug screw 4, the cylinder joint 5 that are connected with the cylinder angle valve air outlet, at plug screw 4 inner chambers turriform spring 2, copper sphere 3, seal rubber pad 25 are housed, cylinder joint 5 rear portions are embedded with three sealing O type cushion rubbers 26; Connecting sleeve 36 anterior external cylindrical surfaces and cylinder joint 5 rear portions are slidingly matched, and its inner cylindrical surface is slidingly matched with the movable lock pin 29 of band central through bore, between connecting sleeve 36 anterior inner cylindrical surfaces and movable lock pin 29 external cylindrical surfaces Returnning spring 28 is housed; Be provided with switch 30 at connecting sleeve 36 middle parts, blast tube is carried out Push And Release control, this switch 30, rotating shaft 15 are tightly connected with connecting sleeve 18 by two sealing O type cushion rubbers 16, rotating shaft 15 tops are provided with handle platform 11 and position-limitting mouth 12, the plate of dialling that rotating shaft 15 lower ends are set contacts with movable lock pin 29 rear ends, stir movable lock pin 29 reaches by handle, close air flue; Cylinder joint 5 rear portions are provided with self-locking mechanism, and locking loose collar 34 is by limiting board 27, locking spring 35 and the matched realization auto-lock function of draw-in groove that is located at cylinder joint 5 rear portions.At cylinder joint 5 rear portions and give vent to anger and between the sebific duct connection nipple 18 reduction valve is housed, it forms two cavitys by locking jacket 6, base 8, upper cover plate 13, plug screw 23, connection nipple 18 by bolt 14 assembling backs, first cavity is connected with blast tube, be provided with the ball sealer (16) that is provided with pressure type Throughput control mechanism in ventilating hole 19, the second cavitys and is positioned at the connection nipple front end between first cavity and second cavity.Described pressure type Throughput control mechanism is by plug screw (24), spring (10), bolt (9), pressure regulation fixed plate (11), elasticity regulator board (12), regulator board (7), hinge (21), sealing plug (20) is formed, pressure regulation fixed plate (11) is contained in elasticity regulator board (12) middle part, elasticity regulator board (12) excircle part is fixed on the joining portion of base (8) and upper cover plate (13), bolt (9) is packed in pressure regulation fixed plate (11) central authorities by nut (22), spring (10) is equipped with on its top, bolt (9) bottom is connected with regulator plate (7) one ends, regulator plate (7) the other end is provided with sealing plug (20), corresponding with ventilating hole (19), regulator plate (7) middle front part and hinge (21) join.
When gaseous-pressure in the passage increases, move on the pressure regulation fixed plate 11, the sealing plug 20 that bolt 9 drives regulator plate 7 front ends moves down, diminish with the distance of ventilating hole 19, thereby reduced combustion gas enters second cavity from first cavity tolerance, and then reduced the delivery pressure of combustion gas, vice versa, thereby play the effect of automatic adjusting gaseous-pressure.When contingencies such as fracture take place in the sebific duct of giving vent to anger, gaseous-pressure increases suddenly with respect to atmospheric pressure in the connector, the ball sealer 16 of being located at connection nipple 18 back cavities is rapidly by on the seal ring 17 of suction and jam-pack connection nipple 18 suction ports, thereby prevented from safety to be brought very big harm because of causing combustion gas unrestrictedly to leak under the unmanned again situation in rapid decompression scene.
