In the V-type modulating valve application of prior art, need modulating valve to control effectively to medium, but existing valve flow characteristic window is ensured by centre of sphere structural characteristics, be difficult to accomplish accurate control.
Moreover existing V-type modulating valve medium inlet runner mostly is through-type, there is the not high shortcoming of precision in the control flow check flow characteristic that comes depending merely on ball core.
Summary of the invention
The utility model mainly solves the deficiency of existing V-type modulating valve, thus provides a kind of inlet channel shape that can design V-type modulating valve by predetermined KV value, reach the object of accurate flow control.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of modulating valve of new structure, include valve body, there are horizontally disposed water inlet flow channel and outlet passage in valve body two ends, vertically be provided with center major diameter with holes above, be provided with blind hole below, described major diameter and blind hole have same axle (in) heart, V-arrangement spheroid is provided with in the cavity in the middle of valve body, V-arrangement spheroid is vertically installed with valve rod, the valve seat coordinated with V-arrangement spheroid is provided with in the water inlet flow channel rear end of valve body, it is characterized in that: the water inlet flow channel of valve body is conical banda reducing runner, namely narrow down to the diameter of a certain particular flow rate COEFFICIENT K vs through conical horn from pipeline nominal diameter, (size that this diameter is benchmark with the economic velocity of user or a certain specific peak rate of flow COEFFICIENT K vs value), outlet passage is pipeline nominal diameter, the diameter of described V-arrangement spheroid and valve seat is less than outlet passage caliber, the conical banda reducing runner of valve body can design according to the KV value requirement of modulating valve, thus makes above-mentioned passage have the characteristic controlling flow, some thrust springs are housed between valve seat and valve body, compensate in order to provide valve seat axial displacement.
The technical solution of the utility model can also be perfect further:
As preferably, described valve seat is a metal ring structure, and valve seat is provided with annular groove near V-arrangement spheroid end, is provided with seal ring in described groove, and the face that described seal ring contacts with V-arrangement spheroid is cambered surface.
As preferably, described valve rod is made up of upper valve rod and lower valve rod; Described upper valve rod one end is connected to the top of V-arrangement spheroid, and the other end is connected with final controlling element through valve body long-neck; Described lower valve rod one end is connected to the bottom of V-arrangement spheroid, and the other end penetrates in blind hole; Be respectively equipped with upper valve sleeve and lower valve sleeve in described long-neck and blind hole, described valve pocket and valve rod form dynamic cooperation.
The beneficial effects of the utility model are:
Its entrance of the valve body of this adjustment ball valve is circular cone undergauge, narrow down to the diameter of a certain particular flow rate COEFFICIENT K vs through conical horn from pipeline nominal diameter, outlet end is the straight tube equal with pipeline nominal diameter, this water inlet passageway design, can require to control the shape of circular cone according to different Kv values, thus reach the object of the Flow characteristics of control media; The bottom of valve body has a blind hole, in order to install Lower shaft sleeve and lower valve rod in blind hole, compares, decrease leakage point with the like product of other structure; The top of valve body has a long hole leading to electric actuator, and for installing valve pocket, upper valve rod, this long-neck structure is conducive to reducing the conduction to electric actuator of the heat of valve pocket inside or cold.
