Description
Technical field
The utility model relates to a kind of fire-protection equipment, particularly relates to a kind of classification pressure release seal arrangement.
Background technique
At present, when cut-off class fluid control device opens or closes when there being pressure, moment of torsion is large, and corresponding fittings acquire intensity is high, adds design and cost of production; Meanwhile, opening or closing the change due to fluid circulation latus rectum in process, the impact of fluid to control gear related accessory sharply being changed, to making control gear, shake occurring and even destroying.Such as, in our daily life, sometimes fetch boiling water tap time, open because hydraulic pressure is high instantaneous water tap can send ear-piercing sound and slight shake.
Model utility content
The purpose of this utility model is solve the problems of the technologies described above and provide a kind of classification pressure release seal arrangement.
For achieving the above object, the technological scheme that the utility model is carried is:
A kind of classification pressure release seal arrangement, comprise pallet and sealing offset plate disposed thereon, described pallet is also provided with the relief hole running through disk body, locknut seat is provided with below described pallet, realize sealing or opening by the position relationship adjusted between described pallet and locknut seat, while the above-mentioned action of execution, fluid realizes pressure release by the flowing of relief hole.
Preferred as one, described pallet is provided with platen by screw, and described platen is provided with for locating and oppressing the indent sealing offset plate.
Preferred as one, described locknut seat is provided with the seal ring for improving the sealing when pallet contacts with locknut seat.
Preferred as one, the below of described locknut seat is provided with locknut, is provided with locknut spline sheet between described locknut seat and locknut, is also provided with sealing gasket between described locknut spline sheet and locknut.
Preferred as one, also comprise axle, described pallet and locknut seat are installed on axle, and described locknut seat is fixedly mounted on axle, and described pallet can move along the axis of axle.
Preferred as one, described axle is provided with setting sleeve, and described setting sleeve is positioned at the top of pallet.
Preferred as one, described axle is provided with away from one end of locknut seat the screw rod mother being convenient to turn axle rotation.
Preferred as one, also comprise valve seat, described valve seat is used for contacting with it when sealing offset plate and moving formation sealed section.
The utility model can realize the classification sealing of convection cell or open, and reduces the moment of torsion caused because pressure is high large when opening, and reduces the overall jitter that high-pressure liquid causes the impact of accessory simultaneously; Release the pressure fusion and the water hammer formed to the damage of Component during closedown.Extensible is the seal arrangement of more multistage number.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the classification pressure release seal arrangement of the present embodiment;
Fig. 2 a is the generalized section of pallet in Fig. 1;
Fig. 2 b is the plan view of pallet in Fig. 1;
Fig. 3 is the structural representation that the present embodiment is applied to fire hydrant.
Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to Fig. 1-3, a kind of classification pressure release seal arrangement, comprise pallet 3 and sealing offset plate 2 disposed thereon, described pallet 3 is also provided with the relief hole 14 running through disk body, locknut seat 4 is provided with below described pallet 3, realize sealing or opening by the position relationship adjusted between described pallet 3 and locknut seat 4, while the above-mentioned action of execution, fluid realizes pressure release by the flowing of relief hole 14.
Described pallet 3 is provided with platen 1 by screw 9, and described platen 1 is provided with for locating and oppressing the indent sealing offset plate 2.Described locknut seat 4 is provided with the seal ring 8 for improving the sealing when pallet 3 contacts with locknut seat 4.The below of described locknut seat 4 is provided with locknut 6, is provided with locknut spline sheet 5 between described locknut seat 4 and locknut 6, is also provided with sealing gasket 7 between described locknut spline sheet 5 and locknut 6.Also comprise axle 11, described pallet 3 and locknut seat 4 are installed on axle 11, and described locknut seat 4 is fixedly mounted on axle 11, and described pallet 3 can move along the axis of axle 11.Described axle 11 is provided with setting sleeve 10, and described setting sleeve 10 is positioned at the top of pallet 3.Described axle 11 is provided with away from one end of locknut seat 4 the screw rod mother 13 being convenient to turn axle 11 rotation.Also comprise valve seat 12, described valve seat 12 is for the formation sealed section that contacts with it when sealing offset plate 2 and moving.
With reference to accompanying drawing 3, the application of art scheme on fire hydrant of the present embodiment is described further: pallet 3 can do quantitative free axial displacement on axle 11, and locknut 6 and locknut seat 4 are fixed on axle 11; Rotating screw bolt mother 13 during closedown, band moving axis 11 and seal arrangement move up, when sealing offset plate 2 close to valve seat 12, due to the free displacement of pallet 3, first automatic shutdown seal under the thrust of fluid, gap is formed between locknut seat 4 and pallet 3, fluid continues through relief hole 14 and flows, pallet 3 pressure at both sides can not sharply be changed, continue to close to locknut seat 4 contact pallet 3 completely and seal, because pressure does not occur sharply to change, decrease water hammer, thus decrease the impact to each parts particularly fire hydrant housing.When opening, rotating screw bolt mother 13, moving axis 11 and locknut seat 4 and locknut 6 is with to move down, under the pressure of fluid simultaneously, pallet 3 and sealing offset plate 2 and valve seat 12 remain sealing, because the bearing area of locknut seat 4 is little, so open torque is also little, after locknut 4 and pallet 3 depart from, liquid is released partial pressure on one side by multiple relief hole 14, reduce the impact of high-pressure flow medium to each part, decrease shake, promote pallet 3 further by the interlock of black box when reaching to a certain degree and cause and beat completely.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
