Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, specifically a bypass-type feed and straight-through discharge one-way valve combination structure. Background Technology

[0002] Conventional horizontal pumps on the market require at least two check valves to operate, and they generally employ a bypass check valve structure, such as... Figure 1 As shown, the material is fed through the lower one-way valve port, enters the working cylinder through the bypass pipe and the overflow tee pipe, and is discharged from the working cylinder through the reciprocating motion of the piston head. This structure is easy to install when there is enough space in the equipment site. However, when the site is small and multiple one-way valves are combined, the resulting piping system is more complex and occupies more space, so there is room for improvement. Utility Model Content

The upper valve body includes an upper plate and a lower plate, with a vertically hollow side plate between the upper and lower plates. The upper plate has a discharge port, and the lower plate has an upper connecting port. A valve core assembly is housed inside the side plate. The lower valve body includes a second upper plate and a second lower plate, with a second side plate between the second upper plate and the second lower plate. The second upper plate has an upper connecting port, and the second lower plate has a feed port. A connection port for connecting to a working cylinder is provided on the second side plate, and a second valve core assembly is housed inside the second side plate.

[0005] A further improvement of the present invention, a bypass-type feed and direct-flow discharge one-way valve combination structure, is that the valve core assembly includes a plate valve core, the upper end of which is provided with a valve core tube, the lower end of which is provided with a sleeve, the valve core tube is inserted into the sleeve, and the sleeve and the valve core tube are provided with a plurality of guide holes.

[0006] A further improvement of the bypass-type feed and straight-through discharge one-way valve combination structure of this utility model is that the second valve core assembly includes a second plate valve core, a second valve core tube is provided on the second plate valve core, a second sleeve is provided at the lower end of the lower plate or the second upper plate, the second valve core tube is inserted into the second sleeve, and a plurality of second guide holes are provided on the second sleeve and the second valve core tube.

[0007] A further improvement of this utility model of a bypass-type feed and straight-through discharge one-way valve combination structure is that the lower plate and the second upper plate are fixedly connected by a connector.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This utility model combines two sets of one-way valve structures in a superimposed design, saving the original connecting tee pipe between the two one-way valves. The top-bottom connection method makes the structure more compact, easier to install and maintain, greatly optimizes the overall pipeline layout, and saves equipment space.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0014] like Figure 2 As shown, a bypass-type feed and direct-flow discharge one-way valve assembly structure includes an upper valve body 1 and a lower valve body 2 arranged vertically. The upper valve body includes an upper plate 3 and a lower plate 4, with a vertically hollow side plate 5 between the upper and lower plates. The upper plate has a discharge port 14, and the lower plate has an upper connecting port 15. A valve core assembly is located inside the side plate. The lower valve body includes a second upper plate 6 and a second lower plate 7, with a second side plate 8 between the second upper plate and the second lower plate. The second upper plate has an upper connecting port 16, and the second lower plate has a feed port 17. The second side plate has a connection port 20 connected to the working cylinder, and a second valve core assembly is located inside the second side plate. The connecting port is connected to the second connecting port.

[0015] The valve core assembly includes a plate valve core 18, with a valve core tube 10 at the upper end of the plate valve core and a sleeve 9 at the lower end of the upper plate facing downwards. The valve core tube is inserted into the sleeve, and the sleeve and valve core tube are provided with several guide holes 11.

[0016] The second valve core assembly includes a second plate valve core 19, a second valve core tube 12 on the second plate valve core, and a second sleeve 13 at the lower end of the lower plate or the second upper plate.
