Abstract
The utility model proposes a kind of V-type modulating valve of U-shaped fluting, comprise valve body, valve gap, valve seat, actuator and be arranged on valve body and valve gap in and for the able to turn on or off ball core coordinating of valve seat and valve rod, lower valve rod, ball core is provided with v-notch, and the middle part of v-notch is provided with U-shaped groove.The utility model makes valve in the situation that of little aperture, use U-shaped groove to carry out the adjusting of extra small flow, thereby the adjusting that uses v-notch to carry out large flow in the situation of large aperture meets usage requirement.
Description
Technical field
The utility model relates to a kind of valve, refers in particular to a kind of V-type modulating valve that had both met large capacity and also meet the U-shaped fluting of extra small flow coefficient.
Background technique
V-type ball valve belongs to the fixing ball valve of single valve seat sealing, has good adjusting function.Between its v-notch and metal seat valve, there is shear action, be particularly suitable for the media such as fibre-bearing, small solid particle, slip, simultaneously, V-notch structure is also beneficial to hydrodynamic pressure is converted to sealing load, strengthen sealing effect, thereby, good sealability there is.
The adjusting operating point regulation range of current known V-type ball cored structure is limited, cannot meet adjusting in a big way.
Model utility content
Limited and cannot meet the problem regulating in a big way in order to solve the adjusting operating point regulation range of existing V-type ball cored structure, the utility model proposes a kind of V-type modulating valve of U-shaped fluting, make valve both meet large capacity and also meet extra small flow coefficient.
The technological scheme that the utility model adopts is: a kind of V-type modulating valve of U-shaped fluting, comprise valve body, valve gap, valve seat, actuator and be arranged on valve body and valve gap in and for the able to turn on or off ball core coordinating of valve seat and valve rod, lower valve rod, described ball core is provided with v-notch, and the middle part of described v-notch is provided with U-shaped groove.The utility model is increased special U-shaped groove design to the v-notch of original ball cored structure, make valve in the situation that of little aperture, use U-shaped groove to carry out the adjusting of extra small flow, thereby the adjusting that uses v-notch to carry out large flow in the situation of large aperture meet usage requirement.
As preferably, between the cell wall of described U-shaped groove and bottom land, be 60 ° of angles.
As preferably, the groove width of described U-shaped groove is 1.5 millimeters.
In the time that needs carry out extra small Flow-rate adjustment, make valve opening below 20%, now valve regulates flow by the special U-shaped groove of ball core, and v-notch is inoperative; In the time that needs carry out large Flow-rate adjustment, make valve opening more than 20%, now valve regulates flow by the v-notch of ball core, and the flow of U-shaped groove is negligible with respect to v-notch.
As preferably, described actuator is side-mounted structure.Actuator is air bladder formula actuator, is arranged on a side of valve body, can fast and easy dismounting.
As preferably, between described valve seat and valve body, connect by dish spring.
As preferably, between described valve seat and valve body, be provided with radial direction seal ring.Between valve seat and valve body, carry out encapsulation process, strengthen sealability.
As preferably, described valve body lower end and valve gap joint are provided with winding seal ring.Valve body lower end and valve gap carry out encapsulation process, strengthen sealability.
As preferably, the lower end outer race of described valve rod is connected to Upper shaft sleeve.
As preferably, the outer race of described lower valve rod is connected to Lower shaft sleeve.
The beneficial effects of the utility model are: make valve in the situation that of little aperture, use U-shaped groove to carry out the adjusting of extra small flow, thereby the adjusting that uses v-notch to carry out large flow in the situation of large aperture meets usage requirement.
