Abstract
The invention discloses an anti-blocking lime milk dosing regulating valve which comprises a valve body, a valve rod and a valve plate, wherein the valve rod and the valve plate are arranged in the valve body; the lower end of the valve plate is provided with a notch with an inverted U-shaped cross section, the bottom of the valve body is provided with an air inlet through hole, and the air inlet through hole is positioned under the notch with the inverted U-shaped cross section at the lower end of the valve plate. The lime milk dosing flow regulator is suitable for lime milk dosing flow regulation, and valve blockage caused by lime milk deposition under the condition of small flow is avoided.
Description
Technical Field
The invention relates to the technical field of control valves, in particular to an anti-blocking lime milk dosing regulating valve.
Background
The lime milk dosing system controls the lime milk dosing amount through a dosing adjusting valve, the adjusting valve comprises a valve body, a valve rod and a valve plate, the valve rod drives the valve plate to move up and down to control the flow during dosing, and in the dosing process, when the small-flow dosing amount needs to be controlled, the lime milk is turbid liquid, particles in the lime milk are easy to deposit, the valve is blocked, and normal dosing cannot be carried out.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides an anti-blocking lime milk dosing regulating valve.
The invention is realized by the following technical scheme.
The anti-blocking lime milk dosing regulating valve is characterized by comprising a valve body (1), a valve rod (2) and a valve plate (3) which are arranged in the valve body (1), wherein the lower end of the valve rod (2) is connected with the upper end of the valve plate (3); the lower extreme of valve plate (3) is opened there is the cross-section for falling U-shaped breach (4), open valve body (1) bottom has air inlet hole (5), and air inlet hole (5) are located valve plate (3) lower extreme and open some cross-sections for falling U-shaped breach (4) under.
Further, valve plate (3) includes circular slab (6), the upper end of circular slab (6) is equipped with draw-in groove (7) that are used for being connected with valve rod (2) lower extreme, the lower extreme of circular slab (6) is opened there is the cross-section for falling U-shaped breach (4).
Furthermore, notches (8) with arc-shaped sections are respectively arranged on two sides of the circular plate (6).
Further, the thickness of the circular plate (6) is gradually reduced from top to bottom.
The valve has the beneficial technical effects that the valve body is provided with the air inlet through hole and the valve plate is provided with the notch, so that the blockage of the dosing valve is effectively avoided, and a large amount of cost is saved. The invention has the advantages of reasonable design, reliable structure, convenient use and the like.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the valve of the present invention.
Fig. 3 is a cross-sectional view of fig. 2.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, an anti-clogging lime milk dosing regulating valve comprises a valve body 1, and a valve rod 2 and a valve plate 3 which are arranged in the valve body 1, wherein the lower end of the valve rod 2 is connected with the upper end of the valve plate 3;
the lower extreme of valve plate 3 is opened there is the cross-section and is reversed U-shaped breach 4, and open 1 bottom of valve body has air inlet hole 5 to air inlet hole 5 is located 3 lower extremes of valve plate and opens some cross-sections and be reversed U-shaped breach 4 under, and air inlet hole 5 is cylindrical through-hole, and air inlet hole 5 is used for connecting compressed air feeder.
Further, the valve plate 3 comprises a circular plate 6, a clamping groove 7 used for being connected with the lower end of the valve rod 2 is formed in the upper end of the circular plate 6, the lower end of the valve rod 2 is clamped in the clamping groove 7, a notch 4 with an inverted U-shaped cross section is formed in the lower end of the circular plate 6, notches 8 with arc-shaped cross sections are respectively formed in two sides of the circular plate 6, and the thickness of the circular plate 6 is gradually reduced from top to bottom.
Sweep easy deposit bottom in valve body 1 through admitting air through-hole 5, prevent that the particulate matter in the lime milk from deposiing in valve body 1, compressed air lets in the U-shaped breach 4 of falling, stirs the lime milk through this region, is applicable to lime milk and adds medicine flow control, avoids leading to the fact the jam of valve because of lime milk deposit under the condition of low discharge.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention. It should be noted that other equivalent modifications can be made by those skilled in the art in light of the teachings of the present invention, and all such modifications can be made as are within the scope of the present invention.
