Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0026] refer to Figure 1-5 , a 150-pound gate valve body seat without a riser mold, including a valve body mold 1, the valve body mold 1 is composed of an upper mold and a lower mold, both sides of the valve body mold 1 are fixedly connected with a first flange 2, the valve A cold iron is installed under the first flange 2 in the body mold 1 to speed up the cooling of the pouring liquid. The middle position of the upper end of the valve body mold 1 is connected with a three-way valve port 3, and the top end of the three-way valve port 3 is fixedly connected with a second valve port. Two flanges 4, a cold iron is installed between the second dark riser 6 and the seco...

The invention relates to the technical field of valve body molds, in particular to a 150-pound gate valve body seat riser-free mold. The 150-pound gate valve body seat riser-free mold comprises a valve body mold. The two sides of the valve body mold are both fixedly connected with first flanges. The middle position of the upper end of the valve body mold communicates with a three-way valve port. The top end of the three-way valve port is fixedly connected with a second flange. First blinder risers are fixedly connected to the upper ends of the sides, far away from each other, of the two firstflanges. First open risers are fixedly connected to the sides, far away from each other, of the two first flanges. A third blind riser is fixedly connected to the position, located below the corresponding first blind riser, of each first flange. Second blind risers are fixedly connected to the two sides of the upper end of the second flange. A second open riser is fixedly connected to one side ofthe upper end of the second flange. A pouring mechanism communicates between the two third blind risers. The valve body mold is internally provided with a plurality of makeup channels. The invention further provides a design method of the 150-pound gate valve body seat riser-free mold. The 150-pound gate valve body seat riser-free mold is simple in structure and worth popularizing.
Description
technical field [0001] The invention relates to the technical field of valve body molds, in particular to a 150-pound gate valve body seat without a riser mold and a design method. Background technique [0002] The valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief. The flow of various types of fluids such as products, gases, mud, various corrosive media, liquid metals and radioactive fluids, the working pressure of the valve can be from 0.0013MPa to 1000Mpa ultra-high pressure, and the working temperature can be from -270℃ ultra-low temperature to 1430 ℃ high temperature. It can be seen from the above that with the acceleration of the reorganization of the valve industry, the future industry will be the competition between the quality and safety of valve products and product bran...
