Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of same or like function from start to finish.The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Fig. 1 is specification is that the threeway exporting 4 points of female threads exempts to adjust and reduce valve structure schematic diagram.Fig. 7 is specification is that the threeway that outlet 2 points is inserted soon exempts to adjust and reduce valve structure schematic diagram.Referring to Fig. 1-7,
Threeway exempts to adjust and reduce pressure valve, 1 and tee T 10 it is responsible for including threeway, bonnet 5, piston 4, plug 8, the threaded band mandrel protecgulum 2 of tee T, protecgulum 20 and the poppet shaft 22 of global formation is included with mandrel protecgulum, being provided with protecgulum snap fit 21 in the front end of protecgulum 20, set nipple 23 in rear end, nipple 23 is for matching with the female thread of tee T.Being formed valve pocket by protecgulum, bonnet, piston in combination (piston 4 and plug 8) is arranged in valve pocket, arranges back-moving spring 3 between piston and poppet shaft, and poppet shaft arranges the first water stream channel 25 of through whole center line.
With mandrel protecgulum 2 by protecgulum together with the Function Integration Mechanism of poppet shaft, it is threadably mounted in arm, and the end of its protecgulum 20 is stretched to bonnet direction and formed protecgulum snap fit 21, is connected with the projection snap fit of bonnet 5, stretches out poppet shaft 22 at the middle part of protecgulum.The front end of poppet shaft arranges O groove 26, arranges O in groove, makes the front end of poppet shaft and piston cavity form the oral area sealing slip pair, the rear portion with mandrel protecgulum 2 and tee T 10 and arrange seal washer 11.Piston outer wall sets O groove 42, arranges O in groove, makes piston and bonnet seal formation sealing slip and pays.Poppet shaft and piston, flexible sealing member between piston and bonnet endoporus, form the low secondary motion that is mutually related, poppet shaft and piston, bonnet coaxiality of inner hole, operation having automatic capturing function, thus improve the precision of its opposed moving members, improve the stability of air relief valve output.
Piston 4 includes being positioned in the middle part of piston inner hole, for installing the plug portion 40 of plug, also includes the cylinder portion 43 stretched to poppet shaft direction, and the diameter of bore in cylinder portion is suitable with the outside diameter of poppet shaft, and cylinder portion is enclosed within poppet shaft and moves along poppet shaft.In the periphery in plug portion, water stream channel 41 is set.
Back-moving spring 3 is enclosed within outside the cylinder portion of piston, and its one end is pressed on piston, the other end is pressed on the root of poppet shaft.
Bonnet 5 includes lid and interval, arranges water hole 51 on interval.Current enter the valve pocket of air relief valve from water hole.
Protecgulum and the root of poppet shaft with mandrel protecgulum 2 are provided with annular groove 27.Annular groove 27 can reduce the impact during poppet shaft is looked for by the mounting structure of protecgulum.
The label J of Fig. 5 represents that valve clearance, poppet shaft end are annular cutting edge structures, and its plug structure of watching with piston mutually optimizes and coordinates the dynamic and static valve clearance J formed, and its characteristic is can to subtract dynamic pressure, also can protect static pressure.
This particular product performance parameters:
It is suitable for intake pressure: 0.1Mpa---1.0Mpa.
