Description

Technical Field

[0001] This utility model relates to a discharge valve, and in particular to an upward discharge valve that facilitates material discharge. Background Technology

[0002] Top-discharge valves are widely used in containers such as stirred tanks. The opening and closing of the top-discharge valve controls the opening and closing of the discharge port of the stirred tank. In actual use, because there is a stirring shaft inside the stirred tank, and the stirring shaft is located above the top-discharge valve, the valve core cannot rise too much when the top-discharge valve is opened, so as to avoid the valve core colliding with the lower end of the stirring shaft and causing damage. This results in a narrow discharge channel formed between the inlet of the valve seat and the valve core when the top-discharge valve is opened, which affects the discharge speed of the stirred tank. Summary of the Invention

[0003] The purpose of this invention is to provide an upward-expanding discharge valve that can increase the discharge channel and facilitate material discharge.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A convenient top-discharge valve includes a valve body, a valve seat, a valve core, and a valve stem connected to the valve core. The valve seat has a feed inlet, and the valve body is fixedly connected to the valve seat. A sealing element is clamped between the valve body and the valve seat at the feed inlet, and the valve core abuts against the sealing element. The valve stem is characterized in that: the upper end of the valve stem is rotatably connected to the valve core; a counterweight is provided on one side of the valve core; the valve stem includes a main valve stem, a first valve stem, and a second valve stem; the first valve stem is rotatably connected to the valve core; the upper end of the second valve stem is rotatably connected to the lower end of the first valve stem; the lower end of the second valve stem is rotatably connected to the upper end of the main valve stem; a sleeve is provided inside the valve body; the first valve stem, the second valve stem, and the main valve stem all extend into the sleeve; and the upper end of the first valve stem extends out of the sleeve.

[0006] With the above structure, when the upper discharge valve is opened, the main valve stem pushes the second valve stem and the first valve stem upward, thereby separating the valve core from the seal. After the valve core rises, the center of gravity of the valve core shifts to one side of the counterweight due to the counterweight block, and the valve core and the first valve stem rotate relative to each other. Then, the lower end of the first valve stem separates from the sleeve, so the first valve stem is driven by the valve core to rotate relative to the second valve stem. Similarly, when the second valve stem extends out of the sleeve at the lower end, it is driven to rotate towards the valve core, and at the same time pushes the valve core away from the top of the valve seat inlet, thereby widening the discharge channel and increasing the discharge speed. Therefore, this utility model can widen the discharge channel and increase the discharge speed when the upper discharge valve discharges material.

[0007] Preferably, the valve core is provided with a first connecting groove, the first connecting groove is provided with a first rotating groove, the upper end of the first valve stem is provided with a first rotating shaft, the first rotating shaft extends into the first rotating groove, and the first valve stem and the valve core are rotatably connected through the first rotating shaft and the first rotating groove;

[0008] The lower end of the first valve stem is provided with a second connecting groove, and a second rotating groove is provided inside the second connecting groove. The upper end of the second valve stem is provided with a second rotating shaft, which extends into the second rotating groove. The second valve stem and the valve core are rotatably connected through the second rotating shaft and the second rotating groove.

[0009] The lower end of the second valve stem is provided with a third connecting groove, and a third rotating groove is provided inside the third connecting groove. The upper end of the main valve stem is provided with a third rotating shaft, which extends into the third rotating groove. The main valve stem and the valve core are rotatably connected through the third rotating shaft and the third rotating groove.

[0010] Preferably, in order to prevent material from accumulating inside the sleeve, the lower end of the sleeve is provided with a discharge hole. Attached Figure Description

[0015] like Figures 1 to 3As shown, this invention discloses a convenient top-discharge valve comprising a valve body 1, a valve seat 2, a valve core 3, and a valve stem connected to the valve core. The valve seat has a feed inlet 4. The valve body is fixedly connected to the valve seat, and a sealing element 5 is clamped between the valve body and the valve seat at the feed inlet. The valve core abuts against the sealing element. The upper end of the valve stem is rotatably connected to the valve stem. A counterweight 6 is provided on one side of the valve core. The valve stem includes a main valve stem 7, a first valve stem 8, and a second valve stem 9. The valve core is provided with a first connecting groove 11, and a first rotating groove 12 is provided in the first connecting groove. A first rotating shaft 13 is provided at the upper end of the first valve stem, and the first rotating shaft extends into the first rotating groove. The first valve stem and the valve core are rotatably connected through the first rotating shaft and the first rotating groove. The lower end of the first valve stem... The valve stem has a second connecting groove 14 at one end, and a second rotating groove 15 inside the second connecting groove. A second rotating shaft 16 is provided at the upper end of the second valve stem, extending into the second rotating groove. The second valve stem and valve core are rotatably connected through the second rotating shaft and the second rotating groove. The valve stem has a third connecting groove 17 at the lower end, and a third rotating groove 18 inside the third connecting groove. A third rotating shaft 19 is provided at the upper end of the main valve stem, extending into the third rotating groove. The main valve stem and valve core are rotatably connected through the third rotating shaft and the third rotating groove. The valve body has a sleeve 20 inside, with the first valve stem, the second valve stem, and the main valve stem all extending into the sleeve. The upper end of the first valve stem extends out of the sleeve, and the lower end of the sleeve has a discharge hole 21.

[0016] With the above structure, when the upper discharge valve is opened, the main valve stem pushes the second valve stem and the first valve stem upward, thereby separating the valve core from the seal. After the valve core rises, the center of gravity of the valve core shifts to one side of the counterweight due to the counterweight block, and the valve core and the first valve stem rotate relative to each other. Then, the lower end of the first valve stem separates from the sleeve, so the first valve stem is driven by the valve core to rotate relative to the second valve stem. Similarly, when the second valve stem extends out of the sleeve at the lower end, it is driven to rotate towards the valve core, and at the same time pushes the valve core away from the top of the valve seat inlet, thereby widening the discharge channel and increasing the discharge speed. Therefore, this utility model can widen the discharge channel and increase the discharge speed when the upper discharge valve discharges material.

[0017] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
