Problems solved by technology
[0002] The current one-way valve mainly drives the valve core to reset through the spring or other reset mechanism in the valve body, so as to realize the purpose of one-way flow of the fluid medium on the pipeline or equipment. The existing technology is characterized by complex structure of the valve body and high cost. In particular, the requirements for the solid content and particle size of the fluid medium are relatively high. When conveying various particle-containing slurries, the reset mechanism is easily stuck or blocked, resulting in the failure of the one-way valve, and the particles in the slurry will Cause the internal structure of the valve to wear and fail

Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with accompanying drawing:
[0014] Such as Figure 1-3 As shown, this one-way valve includes an outlet flange 2, an upper valve body 3, a spherical valve core 4, a lower valve body 5 and an inlet flange 6, the outlet flange 2 communicates with the outlet pipeline 1, and the inlet flange 6 It is connected with the inlet pipe 7, the outlet flange 2 is provided with an outlet flange through hole 2-1, the inlet flange 6 is provided with an inlet flange through hole 6-1; the upper valve body 3 is provided with an upper valve body through hole The hole 3-4 and the liquid outlet 3-3, the inner side of the upper valve body 3 are provided with an upper valve body guide plate 3-1 and an upper valve body limit plate 3-2, and the upper valve body guide plate 3- 1 and the upper valve body limiting plate 3-2 are arranged at intervals along the circumference, and a liquid channel communicating with the liquid out...

The invention relates to a one-way valve. The one-way valve comprises an outlet flange, an upper valve body, a spherical valve core, a lower valve body and an inlet flange, wherein outlet flange through holes are formed in the outlet flange, and inlet flange through holes are formed in the inlet flange; upper valve body through holes and a liquid outlet are formed in the upper valve body, and liquid passages which are communicated with the liquid outlet are formed between upper valve body guide plates; lower valve body through holes and a liquid inlet are formed in the lower valve body, and the liquid inlet is formed in the bottom of a lower valve body pit. When inlet pressure is less than or equal to outlet pressure, the spherical valve core falls on the lower valve body pit in the bottom of the lower valve body to block the liquid inlet, and under the dual function of gravity and the outlet pressure, the spherical valve core and the outlet of the lower valve body pit are closely joined and sealed. The one-way valve disclosed by the invention has the benefits of simple and practical structure, good corrosion resistance property, good abrasion resistance property, good sealing property and long service life, and the one-way valve is used for various sizing agents especially for sizing agents containing granules.
Description
technical field [0001] The invention relates to the field of valves, in particular to a one-way valve. Background technique [0002] The current one-way valve mainly drives the valve core to reset through the spring or other reset mechanism in the valve body, so as to realize the purpose of one-way flow of fluid medium on the pipeline or equipment. The existing technical characteristics are that the structure of the valve body is complex and the cost is high. In particular, the requirements for the solid content and particle size of the fluid medium are relatively high. When conveying various particle-containing slurries, the reset mechanism is easily stuck or blocked, resulting in the failure of the one-way valve, and the particles in the slurry will Cause the internal structure of the valve to wear and fail. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a simple and practical structu...
