Abstract
The utility model discloses a vertically mounted double-pin-tooth gate valve for a power industry and a cement industry, which comprises the following components: a valve body, an inner guiding component, a valve plate, an upper frame, outer sealing components, outer guiding components, pinteeth, a pinteeth guiding component, a transmission shaft and an electric speed reducer. Outer sealing components are provided outside the valve body, and inner guiding components are provided in the valve body. The valve plate is inserted into the valve body. The upper frame is provided above the valve body. The upper frame is internally provided with the outer guiding components, two pinteeth and the pinteeth guiding component. The upper end of each pintooth is connected with the valve plate through a pin, and the lower end is connected with a sprocket wheel. The sprocket wheel is connected with the transmission shaft, and the transmission shaft is connected with the electric speed reducer. Not only are the advantages of smooth transmission and high reliability in gear and rack transmission kept in the vertically mounted double-pin-tooth gate valve for a power industry and a cement industry, but also convenient manufacturing and low cost are obtained.
Description
Technical field
The utility model relates to a kind of gate valve, is specifically related to a kind of electric power, cement industry with double-pin tooth gate valve vertically is installed.
Background technique
Electric power, cement industry use the operating ambient temperature of gate valve below 500 ℃, close external sealed requires high, bore big (common more than 1600mm), stroke long (common more than 1800mm), as adopting general wire rope transmission, the valve plate bumpy motion loses easily and steadily causes jam, and can only lean on the valve plate deadweight to move downward to close when closing and put in place, close the power deficiency; And adopt gear-tooth bar transmission can reach job requirement, but gear, tooth bar required precision are very high, and the processing of long tooth bar is difficult, and cost is too high.Present domestic such valve that lacks cost performance height, reliable transmission.
The model utility content
The purpose of this utility model is in order to solve the deficiencies in the prior art, provides that a kind of external sealed is effective, simple in structure, low cost of manufacture, wearing and tearing are little, reliable transmission, easy to maintenance, electric power that cost performance is high, cement industry be with the vertical double-pin tooth gate valve of installing.
The technical solution of the utility model is: a kind of electric power, cement industry is with double-pin tooth gate valve vertically is installed, comprise valve body, interior guide element, valve plate, upper spider, the external sealed parts, outer guide element, the pin tooth, sprocket wheel, pin tooth guide element, transmission shaft and electric reducer, described valve body outside is equipped with the external sealed parts, interior guide element is installed in the valve body, described valve plate inserts in the valve body, described upper spider is installed in the top of valve body, outer guide element is installed in the upper spider, sell tooth and pin tooth guide element for two, pin tooth upper end is connected by bearing pin with valve plate, pin tooth lower end is connected with sprocket wheel, sprocket wheel is connected with transmission shaft, and transmission shaft is connected with electric reducer.
The transmission of described pin tooth is to drive the pin tooth by sprocket wheel to move up and down along pin tooth guide element, makes the valve plate opening and closing.The pin tooth is to be fixed by universal industrial chain and pin tooth box, and the other end is connected with tension device on the pin tooth box, formation integral body, the effect of replacement tooth bar.Sprocket wheel, chain are the industrial general standardized element all, and cost is low, purchase easily.
Described external sealed parts are made up of sealing seat, sealing gland, stuffing box packing.Stuffing box packing is the Expanded graphite braided packing of rope form square-section, good seal performance.
The supporting of described transmission shaft is a selfaligning ball bearing, and the support loading ability is strong, aligning flexible, the deformability of compensating shaft is strong.
Described valve plate is the seal case beam structure, and the intensity height is out of shape for a short time, and valve plate moves along inside and outside guide element in the course of the work, does not directly contact with valve body, and it is little to rub, do not wear and tear, so the valve plate long service life.
The beneficial effects of the utility model: 1, both kept gear, tooth bar biography stable drive, reliable advantage, simultaneously easy to process, cost is low; 2, the joint shaft bearing aligning is flexible; 3, wearing and tearing are little between valve plate and the valve body; 4, external sealed is effective, and it is high temperature resistant, can reach 600 ℃.
