Description
Technical field
The utility model is related to a kind of gas piping joint, more particularly to a kind of gas piping Self-locking rapid joint.
Background technology
The defect that existing like product is present is：1st, its sealing ring is directly set on valve element, during use, close
Seal is easily blown off by the air-flow of gas；2nd, sealing effectiveness is poor, poor product quality, and product service life is short；3rd, when use,
Grafting is laborious.
Utility model content
Technical problem to be solved in the utility model is that there is provided a kind of gas piping self-locking in view of the shortcomings of the prior art
Formula snap joint.
To achieve these goals, the measure that the utility model is taken：
A kind of gas piping Self-locking rapid joint, including gas-tpe fitting and with gas instrument plug socket, gas-tpe fitting is with using
Connected between gas instrument plug socket by clamping, with being arranged with steel ball support, described use in the interface on gas instrument plug socket
It is arranged with gas instrument plug socket on valve element, the side wall of valve element and offers venthole, is set between the top of valve element and gas-tpe fitting
Being equipped with vulcanization outside spring, the latter end of valve element has the first O-ring seal of rubber system, and the outer cover of valve element is provided with valve pocket, valve pocket
Outside vulcanization have seal washer, the leading portion of valve element is arranged with the second O-ring seal；
Kong Chengyi taper of set in described valve pocket, its diameter is from second O-ring seal one end to the first O-ring seal
It is gradually reduced；
The front end face of described valve element is a diameter of 8-10 millimeters.
The beneficial effects of the utility model：Practicality, production cost is low, and grafting is quick, and good sealing effect improves product
Quality, extends the service life of product, and use cost is low.
Brief description of the drawings
Fig. 1, decomposition texture schematic diagram of the present utility model.
Embodiment
A kind of gas piping Self-locking rapid joint, including gas-tpe fitting 1 and with gas instrument plug socket 2, gas-tpe fitting 1 with
Connected between gas instrument plug socket 2 by clamping, it is described with steel ball support 3 is arranged with the interface on gas instrument plug socket 2
Offer venthole 5 with being arranged with gas instrument plug socket 2 on valve element 4, the side wall of valve element 4, top and the tracheae of valve element 4 connect
Vulcanization outside spring 6, the latter end of valve element 4 is provided between first 1 the first O-ring seal 7 of rubber system, the outer cover of valve element 4
Provided with valve pocket 8, the outside vulcanization of valve pocket 8 has seal washer 9, and the leading portion of valve element 4 is arranged with the second O-ring seal 10.
When the utility model is not used, is not connected with pneumatic tool, the elastic force of spring 6 inserts valve element 4 to gas instrument
One end top pressure of joint chair 2, the second O-ring seal 10 is by top pressure in valve pocket 8, and venthole 5 is set in valve pocket 8, the utility model
Two ends are obstructed, reach the purpose for blocking air-flow.
During use, gas-tpe fitting 1 is connected on the pipeline of source of the gas, and the joint on pneumatic tool is plugged into and uses gas work
Have in plug socket 2, valve element 4 is opened one by the joint driving steel ball support 3 on pneumatic tool, steel ball support 3 to the one end of gas-tpe fitting 1 top
Distance, the second O-ring seal 10 moves a distance, the second O-ring seal 10 and valve pocket 8 with valve element 4 to the one end of gas-tpe fitting 1
Separate, you can the air-flow connected in the utility model.
First O-ring seal 7 directly vulcanizes outside the latter end of valve element 4, it is to avoid during use, the first O-shaped sealing
Circle 7 is blown off by air-flow, extends the service life of product.
Kong Chengyi taper of set in described valve pocket 8, its diameter is O-shaped close from the one end of the second O-ring seal 10 to first
Seal 7 is gradually reduced.When the O-ring seal 10 of valve pocket 8 or second has abrasion, pyramidal structure reaches the effect being deteriorated automatically
Really.
The front end face of described valve element 4 is a diameter of 8-10 millimeters.Compared to conventional product, its end face diameter is more than 12 millimeters, by
Reduce in the area of the front end face of valve element 4, it is more laborsaving, light when insertion pneumatic tool joint.
