进口流量调节阀美国阿卡迪亚品牌

进口流量调节阀Product Description:

The utility model comprises a valve body and a valve core, a liquid chlorine channel is opened in the valve body, both sides of the valve body are provided with inlets and outlets connected with the liquid chlorine channel, the valve core comprises a valve core body and a valve seat, a horizontally placed U-shaped valve seat is installed in the middle of the liquid chlorine channel, the valve seat separates the liquid chlorine channel into a first section of the channel and a second section of the channel, an outer diameter conical section is arranged on the lower end face of the plug block, and two vertical sections of the valve seat are provided with connecting cavities, The valve rod vertically penetrates two communicating cavities, a plurality of clamping blocks are arranged on its outer wall along the circumferential direction of the conical section, a plurality of clamping grooves are opened on the inner wall of the communicating cavity, and a sealing ring is fixed on the lower end face of the conical section. Through the reciprocating movement of the valve rod in the vertical direction, the connection and opening and closing between the liquid chlorine storage tank and the transportation tank can be realized, so as to quickly realize the accurate control of the liquid chlorine flow in the process of liquid chlorine filling, and avoid the leakage of liquid chlorine due to untimely or poor closure accuracy.

characteristic:

It is realized through the cooperation between the valve core and the valve seat, and the driving part of the valve rod is also prone to leakage. Therefore, the support body is fixed on the upper end face of the valve body, the upper end of the support body is fixed with a support plate, the support plate is used to install the driving parts such as the cylinder, the upper end of the valve rod is installed with a driving rod, and the middle of the support body is provided with a cavity filled with filler, The driving rod moves through the cavity in the support body and the support plate in turn and extends upward until it is connected with the output end of the driving part. Similarly, a sealing gasket is installed at the lower end of the support body, which can isolate the lower end of the driving rod from the cavity. The double sealing of the driving rod through the sealing gasket and packing can avoid the leakage of liquid chlorine in the valve body through the driving part of the valve core, and, A shaft sleeve is installed at the connection between the support plate and the support body, and the driving rod moves through the shaft sleeve to ensure that the driving rod can realize up and down reciprocating movement under sealing conditions after being connected with the output end of the driving part.

Principle:

The width decreases downward along the axial direction of the valve stem. The combination of the clamping block and the clamping groove increases the contact area between the conical section and the wall of the connecting cavity, that is, the sealing effect of the primary seal is increased. At the same time, the width of the clamping block decreases downward along the axis of the valve stem. Similarly, the width of the clamping groove on the wall of the connecting cavity also decreases downward along the axis of the valve stem, that is, the residual amount of liquid chlorine in the clamping groove can be reduced when the liquid chlorine flow path is cut off, and during the contact between the clamping block and the clamping groove, The deformation caused by the extrusion of the clamping block will be limited in the part where the width of the clamping groove gradually decreases, that is, the interaction force between the clamping block and the clamping groove increases in the downward direction along the axial direction of the valve stem, so as to increase the sealing effect of the primary seal.
