Description
Technical Field
The utility model relates to an improvement invention of a melt valve, in particular to an improvement invention of a melt valve based on guide drainage.
Background
In the prior art, the melt valve is used for cutting off or opening the melt circulation, the melt is easy to remain on the upper part of a valve cavity through which less melt passes, and the remaining melt is accumulated, so that the cleaning and the flux of the melt valve are seriously influenced, and troubles are brought to actual production.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a remaining fuse-element valve based on direction drainage of fuse-element in reducing valve body center runner.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of fuse-element valve based on direction drainage, including valve body, valve rod and driving hand wheel, be equipped with central runner in the valve body, in the valve rod is portable to stretch into central runner, corresponding valve rod outer end links to each other with the driving hand wheel transmission, and valve rod inner is equipped with the valve head, and this valve head blocks cooperation, its characterized in that with central runner: the valve body is provided with an outlet melt pipe and an inlet melt pipe which are distributed left and right, and the outlet melt pipe and the inlet melt pipe are respectively and radially communicated with the left end and the right end of the central flow passage; the central flow passage is provided with a horn-shaped intercepting section, the inner diameter of a left port of the intercepting section is larger than that of a right port of the intercepting section, the valve head can stretch into the intercepting section from the left port of the intercepting section and is in sealing fit with the right port of the intercepting section, and the right end of the valve head is provided with an inclined plane or an arc surface for guiding the melt to flow upwards.
The valve head is eccentric downwards in the intercepting section.
The outlet melt pipe is positioned at the lower side of the valve body, and the inlet melt pipe is positioned at the upper side of the valve body.
The left end face of the central runner is provided with an inclined plane or a cambered surface for guiding the melt to flow downwards into the outlet melt pipe.
The beneficial effects of the utility model are that the fuse-element valve based on direction drainage after the improvement through the central runner at the valve body in set up tubaeform the section of damming to set up the inclined plane or the cambered surface that guide fuse-element upwards flows at the valve head right-hand member, lead the drainage to the fuse-element, wash central runner automatically, reduce the fuse-element and remain.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. In the embodiment, the melt valve based on guide drainage comprises a valve body 1, a valve rod 2 and a driving hand wheel 3, wherein a central flow passage 4 is arranged in the valve body 1, the valve rod 2 can movably extend into the central flow passage 4, the outer end of the corresponding valve rod 2 is connected with the driving hand wheel 3 in a transmission manner, a valve head 5 is arranged at the inner end of the valve rod 2, the valve head 5 is in cut-off fit with the central flow passage 4, an outlet melt pipe 6 and an inlet melt pipe 7 which are distributed on the left and right sides are arranged on the valve body 1, and the outlet melt pipe 6 and the inlet melt pipe 7 are respectively communicated with the left end and the right end of the central flow passage 4 in the radial direction; the central flow passage 4 is provided with a horn-shaped intercepting section 8, the inner diameter of a left port of the intercepting section 8 is larger than that of a right port, the valve head 5 can extend into the valve head from the left port of the intercepting section 8 and is in sealing fit with the right port of the intercepting section 8, and the right end of the valve head 5 is provided with an inclined plane or an arc surface 51 for guiding melt to flow upwards.
The utility model discloses an operating principle, 3 transmission valve rods 2 of driving hand wheel move to a left side, valve head 5 is opened, then the fuse-element gets into 4 right-hand members of central runner of valve body 1 through import fuse-element pipe 7 to flow through 5 tops of valve head under the effect of the inclined plane of 5 right-hand members of valve head or cambered surface, the part flows through 5 below of valve head, get into export fuse-element pipe 6 outwards outflow together, with this direction drainage to the fuse-element of realization, and wash away 4 upper portions of central runner that remain the fuse-element easily.
As a further improved embodiment, the valve head 5 is eccentric downwards in the intercepting section 8, so that the melt is guided to pass above the valve head 5 more, and the inner wall of the flow channel is washed from top to bottom.
As a specific embodiment of further improvement, the outlet melt pipe 6 is positioned at the lower side of the valve body 1, and the inlet melt pipe 7 is positioned at the upper side of the valve body 1, so that the melt can flow from top to bottom by means of the gravity of the melt.
As a further improved embodiment, the left end surface of the center flow channel 4 is provided with a slope or arc surface 41 for guiding the melt to flow downward into the outlet melt pipe 6, so as to guide the melt for the second time, thereby further reducing the residue.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
