Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valves, in particular to an oblique clamp-type pressure reducing valve. Background Art

[0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure by adjusting it, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of reducing pressure. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure after the valve is balanced with the spring force, so that the pressure after the valve is kept constant within a certain error range. The pressure reducing valve is divided into proportional pressure reducing valve, action pressure reducing valve and pilot pressure reducing valve according to the type. Among them, the action pressure reducing valve has a simple structure and is easy to install. It is often used in small-diameter pipe scenes. However, the pressure reducing components of the traditional action pressure reducing valve are usually set inside the valve body, which is inconvenient to maintain when a fault occurs, especially the internal adjustable adjustment rod. Moreover, the adjustment system is complicated and the operation is troublesome.

[0003] In order to effectively adjust the water pressure of the water supply pipeline automatically and the structure is simple and easy to maintain, a Chinese patent application, announcement number: CN202402739U, discloses an inclined pressure reducing valve, which is composed of a valve body, a valve core assembly and a valve cover. The upper opening of the valve body is inclined toward one end of the water inlet. The valve core assembly is composed of a sealing pressure ring, a pressure spring, an adjusting pressure cover, a pressure regulating driving rod, a spring seat buckle bowl, a positioning nut, a fine-tuning telescopic sealing bowl, a valve core body, a valve core connecting screw, a sealing rubber ring, a support rod, a gasket, a sealing gasket, a valve top and a locking nut. The valve core connecting screw is locked with a positioning nut and a locking nut. The upper part of the valve core body is a pressure regulating chamber, and the lower part is a flow control chamber. Pressure regulation is implemented through the pressure regulating chamber and the flow control chamber. The utility model has a scientific design and a reasonable structure. It uses the water pressure of the water source to realize automatic water pressure adjustment and is widely used in agricultural water-saving irrigation.

[0004] This solution still has some shortcomings in application. Since the pressure reducing components are fixed in the valve body, it is difficult to replace and maintain the components when a failure occurs, which can easily shorten the service life of the pressure reducing valve and affect the normal water supply. In addition, for some pipelines with large water supply, controlling the water pressure by lifting the piston is not applicable, especially for the main water supply pipeline. Therefore, it is necessary to improve the structure of the pressure reducing valve so that it can better regulate the water pressure and is easy to operate and maintain. It is suitable for water supply pipelines of various diameters and improves the applicability of the pressure reducing valve. Utility Model Content

[0019] The specific implementation of the present utility model will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, an oblique clamp-type pressure reducing valve comprises a left valve body 1 and a right valve body 2, wherein the left valve body 1 and the right valve body 2 are connected in a symmetrical oblique flange, an adjusting seat 3 is mounted on the top of the right valve body 2, a valve seat 4 is sleeved on the right side of the left valve body 1, a rotary bearing 5 is arranged on the front side of the lower part of the right valve body 2, a valve plate 6 is arranged on the front side of the rotary bearing 5, and the valve plate 6 is rotatably connected to the rotary bearing 5, a connecting block 7 is arranged on the lower part of the rear side of the valve plate 6, a valve stem 8 is arranged on the rear side of the connecting block 7, and the top of the valve stem 8 extends to the adjusting seat 3, and the valve plate 6 can be raised and lowered through the valve stem 8 and is sealingly sleeved with the valve seat 4.

[0021] Furthermore, a rubber ring 9 is sleeved on the front side of the right valve body 2 , and first limit blocks 91 are respectively provided at the upper and lower parts of the rubber ring 9 , and the first limit blocks 91 are adapted to limit the position of the valve plate 6 .

[0022] Furthermore, a hinge buckle 10 is installed between the connecting block 7 and the valve stem 8 .

[0023] Furthermore, a spring seat 11 is provided at the top of the adjustment seat 3 , and a telescopic spring 12 is built into the spring seat 11 , and the bottom of the telescopic spring 12 is connected to the top of the valve stem 8 .

[0026] [Example]

[0027] First, the water supply enters from the left valve body 1 and flows to the right valve body 2 through the valve plate 6. Then, the valve plate 6 is connected to the rotating bearing 5 and can rotate downward along the rotating bearing 5. The valve plate 6 can adjust the inclination angle by abutting against the telescopic spring 12 through the valve stem 8. The telescopic spring 12 applies pressure to the valve stem 8 to act on the valve plate 6, and the pressure is adjusted by the opening amplitude of the valve plate 6 along the valve seat 4.
