Abstract
The utility model relates to an automatic balanced stopping regulating valve, which comprises a valve body, a valve base, a valve cover, a valve rod, a control diaphragm and a control cavity. A control spring is mounted inside the control cavity. The regulating valve is mainly characterized in that a regulating valve flap and a stop valve flap are respectively arranged on two sides of an outlet and an inlet of the valve base, and the regulating valve flap is positioned on the inlet side of the valve base, thereby realizing stabilizing flow and pressure of media on the valve outlet. The stop valve flap positioned on the outlet side of the valve base can realize closing and opening the valve via the valve rod. The regulating valve has the advantages of realizing stabilizing flow and pressureof media on the outlet of the valve, forcedly closing the valve and having low flow resistance.
Description
Technical field
The utility model relates to a kind of valve, specifically about a kind of automatic balance type modulating valve.
Background technique
The automatic balance type modulating valve is the variation that utilizes the valve export side pressure, feeds back to the opening degree that flap is regulated in the controlling diaphragm chamber, realizes the control to valve export flow and pressure.Existing automatic balance type modulating valve, generally form, control spring is housed in control chamber, and be connected with valve export by valve body, valve seat, flap, valve rod, diaphragm and control chamber, by design, can realize stablizing the pressure and the flow of valve export to control spring.Yet, existing automatic balance type modulating valve, its flap is located at the valve seat outlet side, need pressure medium to promote flap and connected device, stream decreases bigger, and this structure can only play the pressure and the flow effect of stablizing valve export, can not realize closing fully pipeline flow, so on pipeline shut-off valve will be installed in addition, this is the major defect of existing product.
The model utility content
The purpose of this utility model is the problem that exists at prior art, and it is little to provide a kind of stream to decrease, and automatic balance type cut-off type modulating valve that can the positive closing pipeline flow.
The technological scheme that realizes the utility model purpose comprises valve body, valve seat, valve gap, valve rod, control diaphragm and control chamber, control spring is housed in control chamber, mainly be to be respectively equipped with in the import and export both sides of valve seat to regulate flap and fluid stopping flap, regulate the suction side that flap is positioned at valve seat, be connected with the control diaphragm, the fluid stopping flap is positioned at the outlet side of valve seat, is connected with valve rod, and is shaped on the sealing surface that cooperatively interacts with valve seat.
The utility model beneficial effect compared with prior art is to be provided with respectively in the import and export both sides of valve seat to regulate flap and fluid stopping flap, regulate the suction side of flap at valve seat, realize stablizing the flow and the pressure of valve export medium, the fluid stopping flap is at the outlet side of valve seat, realize the unlatching of valve or close by valve rod, both realized stablizing the flow and the pressure of valve export medium, again can the positive closing valve, and decrease little to MEDIA FLOW.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Automatic balance type cut-off type modulating valve as shown in Figure 1, comprise valve body 1, valve gap 10 valve seats 2, valve rod 3, control diaphragm 4 and control chamber, control spring 5 is housed in control chamber, be respectively equipped with adjusting flap 6 and fluid stopping flap 7 in the import and export both sides of valve seat 2, regulate the suction side that flap 6 is positioned at valve seat 2, be connected with control diaphragm 4, fluid stopping flap 7 is positioned at the outlet side of valve seat 2, be connected with valve rod 3, and be shaped on the sealing surface that cooperatively interacts with valve seat 2.Control chamber is connected with valve body 1 outlet passage by aperture, and control spring 5 and control are provided with spring seat 8 between the diaphragm 4, and the suction side of valve seat 2 is provided with porous filtering net 9, and will regulate flap 6 and cover between filter screen 9 and the valve seat 2.Be fitted between valve body 1 and the bottom 11 around the control diaphragm 4, and constitute control chamber with bottom 11.
