Abstract
The invention discloses a vertically installed gate valve with double pin teeth for the electric power industry and cement industry, which comprises a valve body, an inner guide component, a valve plate, an upper stand, an outer sealing component, an outer guide component, pin teeth, a chain wheel, a pin tooth guide component, a transmission shaft and an electric speed reducer, wherein the outer sealing component is installed outside the valve body; the inner guide component is installed in the valve body; the valve plate is inserted into the valve body; the upper stand is installed above the valve body; the outer guide component, the two pin teeth and the pin tooth guide component are installed in the upper stand; the upper end of each pin tooth is connected with the valve plate through a pin shaft; the lower end of each pin tooth is connected with the chain wheel; the chain wheel is connected with the transmission shaft; and the transmission shaft is connected with the electric speed reducer. The invention reserves the advantages of smoothness and reliability of gear and rack transmission, and simultaneously has convenient processing and low cost.
Description
Technical field
The present invention relates to a kind of gate valve, be 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.
Summary of the invention
The objective of the invention is in order to solve the deficiencies in the prior art, provide 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.
Technological scheme of the present invention 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.
Beneficial effect of the present invention: 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 ℃.
