Model utility content
The purpose of this utility model is to provide a kind of not only reliable performance, and the pressure adjustable overvoltage protection valve of pressure adjustable, easy to adjust.
For realizing above-mentioned object, the technical solution of the utility model is: the overvoltage protection valve that a kind of pressure is adjustable, comprise valve body, in valve body, be provided with the valve pocket that runs through whole valve body, on valve body, be provided with the exhaust port being communicated with valve pocket, in valve pocket, be from left to right provided with successively twin adapter, coniform seal ring, elasticity plug, spring two, spring seat, joint, one end of twin adapter is connected with valve body, and coniform seal ring, elasticity plug, spring two, spring seat are contained in valve pocket; Coniform seal ring is corresponding with exhaust port, and the large end of coniform seal ring contacts with twin adapter, and small end props up valve body; The right-hand member of elasticity plug is enclosed within spring two, and spring two is arranged in spring seat; On the valve body corresponding with elasticity plug, be provided with the overvoltage protection hole being communicated with valve pocket, in protection hole, be provided with needle, the upper end of this needle is provided with Regulation spring, and screw thread spring cap seal is passed through in protection hole in the upper end of Regulation spring.
Preferably, described twin adapter is cylindric.
Preferably, the material of described coniform seal ring is silica gel.
Preferably, the material of described coniform seal ring is vapour rubber.
Preferably, described elasticity plug is spherical silica gel head.
Preferably, between coniform seal ring and elasticity plug, be also provided with spring one, one end of spring one contacts with coniform seal ring, and the other end props up valve body.
The utility model adopts above-mentioned structure, when water flows into from A, through the hole of coniform seal ring 3, produces pressure coniform seal ring is expanded, and therefore can seal up exhaust port; When stopping supplying water or when steam mixes, A place pressure reduces, coniform seal ring restores to the original state, and exhaust port is opened, and gas-vapor mix will be discharged from exhaust port, thereby play the object of air-discharging, and can not leak, easily reset, reliable performance; Push elasticity plug open, current flow out from B.When pressure is excessive; while being greater than Regulation spring setting elastic force; needle is moved upward and opens protection hole; play pressure release object; reach overvoltage protection object; and Regulation spring mounts cover in protection in hole by screw thread spring, can regulate by screw thread spring cup the decrement of Regulation spring, thereby reach the object that regulates pressure.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model exploded view.
In figure: 1 twin adapter, 2 seal rings, 3 coniform seal rings, 4 valve bodies, 41 valve pockets, 42 exhaust ports, 43 protect well hole, 5 spring one, 6 screw thread spring cups, 7 Regulation springs, 8 needles, 9 elasticity plugs, 10 spring two, 11 spring seats, 12 joints.
Embodiment
As illustrated in fig. 1 and 2, the overvoltage protection valve that pressure of the present utility model is adjustable, comprise valve body 4, in valve body 4, be provided with the valve pocket 41 that runs through whole valve body 4, on valve body 4, be provided with the exhaust port 42 being communicated with valve pocket 41, in valve pocket 41, be from left to right provided with successively twin adapter 1, coniform seal ring 3, spring 1, elasticity plug 9, spring 2 10, spring seat 11, joint 12, one end of twin adapter 1 is connected with valve body 4, the other end of twin adapter 1 is connected use by seal ring 2 with other pipe fitting, coniform seal ring 3, spring 1, elasticity plug 9, spring 2 10, spring seat 11 is contained in valve pocket 41, coniform seal ring 3 is corresponding with exhaust port 42, and the large end of coniform seal ring 3 contacts with twin adapter 1, and small end contacts with one end of spring 1, and the other end of spring 1 props up valve body 4, the right-hand member of elasticity plug 9 is enclosed within spring 2 10, and spring 2 10 is arranged in spring seat 11, on the valve body corresponding with elasticity plug 94, be provided with the overvoltage protection hole 43 being communicated with valve pocket 41, in protection hole 43, be provided with the needle 8 that can block protection hole in setting pressure, the upper end of this needle 8 is provided with Regulation spring 7, and the upper end of Regulation spring 7 is enclosed in protection hole 43 by screw thread spring cup 6.In the present embodiment, twin adapter 1 is cylindric, and it is to be fixed on valve body 4 by internal and external threads.The material of coniform seal ring 3 is silica gel.The material of coniform seal ring 3 can be also vapour rubber.Elasticity plug 9 is spherical silica gel heads.
