Example Embodiment

[0016] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0017] like figure 1 A novel anti-scouring regulating valve shown includes a valve body 1 , a valve cover 2 , a valve seat 3 , a valve stem 4 , a valve core 5 and a throttling element 6 .

[0018] On the upper end of the valve body 1, there is a valve cover 2 used in conjunction with it. The valve cover 2 is fixed between the valve body 1 by bolts. In the valve body 1, there is a channel 7 for medium circulation and a valve stem 4. A movable cavity, the valve stem 4 extends from the middle of the valve cover 2 into the cavity of the valve body 1 from top to bottom, a valve core 5 is connected to the lower end of the valve stem 4, and a valve core 5 is arranged below the valve core 5 The valve seat 3 installed on the valve body 1, and the sealing surface of the valve core 5...

Abstract

The invention relates to a novel anti-scouring adjusting valve which comprises a valve body, a valve deck, a valve rod, a valve element, a valve base and a throttling element. The throttling element is formed by jointly stacking a plurality of pore plate assemblies. Each pore plate assembly comprises a pore plate body, wherein the pore plate body is annular, an annular groove is formed in the lower end of the pore plate body, the annular groove is divided into two coaxial annular ducts through a partition plate, the annular ducts are the annular duct A and the annular duct B in sequence from interior to exterior, a hole A communicated with the annular duct A is formed in the inner wall of the pore plate body, a hole B communicating the annular runner A with the annular runner B is formed in the partition plate, a hole C communicated with the annular runner B is formed in the outer wall of the pore plate body, and the hole A, the hole B and the hole C are distributed in a staggered mode. The novel anti-scouring adjusting valve has the advantages that the throttling element is designed to be of the combined structure of the multiple annular runners, and the pressure and flow speed of a medium can be effectively decreased, so that the characteristic that the flow of a medium is adjusted in a balanced and stable mode is achieved, and no fluctuations are generated.

Description

technical field [0001] The invention relates to a valve, in particular to a novel anti-scouring regulating valve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, by receiving the control signal output by the adjustment control unit, with the help of power operation to change the flow area of ​​the medium, to achieve the final control device for flow, pressure, liquid level and other process parameters. It is generally composed of actuators and valves. According to the stroke characteristics, the control valve can be divided into straight stroke and angular stroke; according to the power used by the actuator it is equipped with, it can be divided into three types according to its function and characteristics: linear characteristic, equal percentage characteristic and parabolic characteristic. The control valve is suitable for air, water, steam, various corrosive media, mud, oil and other media. ...
