Abstract
The utility model relates to an airtight lateral plug board valve. A rack is arranged on a valve plate, and a transmission shaft is arranged in the middle of a valve body. By means of crosswise design of gear connection, a gear transmission shaft can achieve the aim of opening and closing of the valve plate by positive and negative rotating of a hand shank. By means of design of a crosswise positioning transmission gear and a chain opening-closing valve, the length of the valve plate is shortened, when the valve is closed, no redundant valve plates are left outside. No matter whether the valve is in opening state or in closing state, fly ash leaking can not exist in the outer portion of the valve body, and fly ash leaking can cause fly ash second pollution. The airtight lateral plug board valve is simple in structure, good in sealing performance, small in size, low in failure rate and the like, and is suitable for being applied to a boiler flying ash storage ash bank, a dust remover ash hopper blanking opening, an occasion of blocking and opening of flying ash materials, and the like.
Description
Technical field
The utility model relates to deduster structure field, especially a kind of airtight side direction push-pull valve.
Background technique
Coal fired boiler is used very extensive in China, the industries such as particularly thermal power generation, cement building material, chemical industry metallurgical are very extensive.Along with the attention of country to environmental protection, boiler smoke is administered rapid technological improvement, and the flying dust major pollutants that deduster is collected also are to utilize thing.Because traditional main transmission part screw rod of push-pull valve and coupled valve plate are exposed externally, thereby and owing to reaching the principle of open and close valve for the clockwise and anticlockwise by screw rod, it is arranged as vertical layout, so that its volume is longer, valve body is larger, and exposed screw rod and valve plate vulnerable to pollution and damage are used effort, poor sealing, the problems such as rate of fault height.
Summary of the invention
The purpose of this utility model is little, the good leak tightness of a kind of volume of design, the light and handy airtight side direction push-pull valve of use.The technical solution of the utility model is so to realize:
A kind of airtight side direction push-pull valve, comprise valve body and valve plate and handle wheel provided thereon, be connected with the transmission shaft of being located in the valve body on the handle wheel, described transmission shaft is located between the valve body two long limit mid points, and transmission shaft is provided with a driving gear, and described valve plate inboard is provided with the tooth bar with the gear engagement.
As preferably, tooth bar and transmission shaft are arranged vertically.
As preferably, transmission shaft one end is provided with self-aligning bearing and sealing cover.
As preferably, the length of described tooth bar is consistent with the length of valve plate.
The airtight side direction push-pull valve of the utility model design, at valve plate parallel rack has been installed, transmission shaft is set in the middle of valve body, gear by transverse design connects, gearing shaft opens and closes the valve plate purpose by the handle clockwise and anticlockwise to reach, the design of located lateral driving cog wheel and rack switch valve, make the shorten length of valve plate, there is not unnecessary valve plate in the time of throttle down externally, the spiro rod length that does not also have original screw drive design to stretch out in the time of Open valve, so that the valve body longitudinal length shortens three minutes one, and the valve plate during opening state, be enclosed in the valve body by originally exposing to become in the valve body outside, so no matter be to open or closed condition, the outside of valve body does not have flying dust and leaks, and causes the flying dust secondary pollution.Therefore the utlity model has that overall volume is little, good airproof performance, the characteristics such as easy to operate.Applicable boiler fly ash is stored the applications such as the blocking-up of flying dust material, unlatching such as grey storehouse, dust collector ash hopper feed opening.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is left views of Fig. 1.
Accompanying drawing 3 is plan views of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the technical solution of the utility model is described in further detail.
Embodiment: with reference to the accompanying drawings, a kind of airtight side direction push-pull valve, comprise valve body 1 and valve plate 2 and handle wheel 10 provided thereon, be connected with the transmission shaft 8 of being located in the valve body 1 on the handle wheel 10, described transmission shaft 8 is located between the mid point of 1 liang of long limit of valve body, and transmission shaft 8 is provided with a driving gear 9, and described valve plate 2 inboards are provided with the tooth bar 4 with gear 9 engagements, and tooth bar 4 is arranged vertically with transmission shaft 8.The length of described tooth bar 4 is consistent with the length of valve plate 2.Transmission shaft 8 one ends are provided with self-aligning bearing 6 and sealing cover 7.
The valve closing state, by valve plate 2 with the flying dust logistics blocking-up top at valve; Need Open valve, by manually clockwise rotating handle wheel 10, by driving gear 9 and tooth bar 4 gear motions, valve plate 2 moves the free fall from top to bottom of flying dust material to arrow points.Throttle down, by manually rotating counterclockwise handle wheel 10, valve plate 2 is closed, the blocking-up of flying dust material.
