Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a single-port side hole pressure reducing combination valve. Background Art

[0002] The pressure reducing valve, also known as the safety valve, is a valve that adjusts the inlet pressure to the preset outlet pressure through its own mechanical components and automatically maintains a stable outlet pressure by relying on the energy of the medium itself.

[0003] However, most of the existing valves have a single function and need to be connected with various pipes and joints. At the same time, too many pipe joints increase the risk of leakage. In addition, it is difficult to reasonably arrange these single-function valves in a small space. Based on the shortcomings of the existing technology, the utility model designs a single-port side hole pressure reducing combination valve. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a single-port side-hole pressure-reducing combination valve to overcome the above-mentioned technical problems existing in the prior related technology.

[0005] The utility model provides the following technical solutions: a single-port side-hole pressure-reducing combination valve, comprising a valve body, the valve body comprising an inlet end, an outlet end and an adjusting end, the adjusting end being arranged at the top of the valve body, the adjusting end being sequentially mounted with a clamping cap, a rubber gasket, a pressure-reducing valve screw rod, a filter screen, a plastic core, a sealing diaphragm, a stainless steel pressing sheet, a pressure-reducing spring and a pressure-reducing valve cap, the outlet end being arranged with a safety valve, the safety valve being detachably connected to the outlet end through a connecting cap and a sealing ring being arranged in the connecting cap, the safety valve being sequentially mounted with a water-stopping diaphragm, a water-stopping diaphragm sleeve, a red paper gasket, a safety spring, an adjusting rod, a plastic hexagonal cap, a safety adjusting screw, a retaining ring and a handwheel, interfaces being arranged on both sides of the outlet end, one side of the safety valve and the bottom of the valve body. When in use, the hand wheel is rotated to open the valve body, and the medium flows to the back of the valve. At the same time, the pressure from the back of the valve enters the valve body and is directly transmitted to the stainless steel pressing plate, and the pressure is kept in a balanced state through the pressure reducing spring to achieve the purpose of pressure reduction. The pressure reducing valve and pressure stabilizing valve can also use water pressure for self-regulation under complex and changeable working conditions. When the inlet pressure and flow rate change, the pressure and flow rate at the outlet are kept stable. The overall structure of the valve body is compact, which is easy to install and carry, and improves the reliability of the product.

[0006] As a preferred technical solution of the utility model, a check core is installed on the outlet end, and copper ferrules and ferrule caps are provided on the inlet end, the outlet end, the interface on one side of the safety valve and the interface at the bottom of the valve body.

[0007] As a preferred technical solution of the utility model, O-rings are provided on the interfaces on both sides of the outlet and at both ends of the filter screen.

[0008] As a preferred technical solution of the utility model, the interfaces on both sides of the outlet end are respectively provided with a black plug and an octagonal plastic plug cap.

[0009] As a preferred technical solution of the utility model, a pressure reducing adjusting screw and a hexagonal copper gasket are provided on the pressure reducing valve cap.

[0010] As a preferred technical solution of the utility model, a logo cover is provided on the hand wheel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The single-port side-hole pressure-reducing combination valve is used to open the valve body by rotating the hand wheel, and the medium flows to the rear of the valve. At the same time, the pressure from the rear of the valve enters the valve body and is directly transmitted to act on the stainless steel pressing plate and the pressure is kept in a balanced state through the pressure-reducing spring to achieve the purpose of pressure reduction. The pressure-reducing and pressure-stabilizing valve can also use water pressure to self-regulate under complex and changeable working conditions. When the inlet pressure and flow rate change, the pressure and flow rate at the outlet are kept stable. The overall structure of the valve body is compact, which is easy to install and carry, and the reliability of the product is improved. BRIEF DESCRIPTION OF THE DRAWINGS
