Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, the multifunctional flow-regulating pressure-regulating valve comprises a valve body 4, a bearing 2 is fixed at the left top end inside the valve body 4 through a screw, a connecting rod B1 is installed on the bearing 2 through a valve shaft C3, the connecting rod B1 is connected with a connecting rod a15 through a valve shaft B17 and a pin B18, the other end of the connecting rod a15 is installed on a valve clack seat frame 9 through a valve shaft a10 and a pin a11, the valve clack seat frame 9 is installed on a valve sleeve 5 through a bolt 6, a spray hole squirrel cage 14 is installed outside the valve sleeve 5, a clack pressure plate 12 is fixed on the spray hole squirrel cage 14 through a sealing ring 8, and a valve cover 13 is installed at the opening of the valve body 4 through a bolt and a bolt cap 7. The valve sleeve 5 is sleeved in the valve body 4. The valve clack seat frame 9 is of a triangular structure. The valve body 4 and the valve sleeve 5 are hermetically installed through an O-shaped sealing ring 16. Symmetrical hedging water inlets are formed in the spraying hole squirrel cage 14. And a groove is formed in the outer side of one end, close to the bearing 2, of the valve body 4. The valve housing 5 is in a trapezoidal structure.

The flow-regulating pressure-regulating valve is a valve capable of meeting various special regulations, and its regulation function is implemented by that a cylinder similar to piston net is axially moved in the valve cavity, its stroke is identical to the direction of water flow in the pipe, and the valve body is divided into valve body 4 and valve sleeve 5, and the valve sleeve 5 is equipped with streamlined flow-guiding column and connected with valve body 4, and the end surface of upstream of valve sleeve 5 is made into the form of ball. A connecting rod A15 guided by a bronze guide rail is arranged in the valve sleeve 5, the rotary motion of each connecting rod is guided by an internal crank slider mechanism to be changed into the axial motion of a piston, water flow enters the shell from an axial arc shape, a flow passage in the valve is in an axisymmetric type, and no turbulent flow is generated when fluid flows through the valve. The flow passage area of the outlet part is changed through the axial movement of the piston, so that the functions of flow regulation and pressure regulation are realized. The flow profile in the valve chamber is annular regardless of the position of the piston, so that linear adjustment is achieved over a wide operating range.

When the pressure or flow is regulated, the flow area of the fluid starts to be controlled through the jet hole squirrel cage-14 in the valve, so that the effects of reducing pressure and regulating flow are achieved. When the upstream pressure or flow increases or decreases, a signal is sent to the control box through the downstream pressure or flow sensor. The control box sends a feedback signal to the valve electric device. And further the opening of the valve is increased or decreased, and finally the purposes of pressure regulation and constant downstream flow are achieved.

The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
