Description
Technical field
Originally be that invention relates to a kind of pulling-down formula gate valve, it is made up of valve body, valve gap, flashboard, valve seat, valve rod and handwheel, drives valve rod by handwheel, and flashboard is moved up and down along sealing surface of seat.
Background technique
Gate valve can divide two classes by threaded stem, and the one, the rising stem (RS.) formula, the 2nd, blind rod type, the rising stem (RS.) formula is commonly called as and also is called pull-rod type, and it is valve rod rotation back lifting, and drives the flashboard lifting; Blind rod type is the fixing rotation of valve rod, then drive lifting nut, make the flashboard lifting, but the common shortcoming of this dual mode is exactly that rising or falling speed is slow, because gate valve is to use scope wide, as large-scale Sewage Plant, oil factory, the shipyard, it is the valve of class that gate valve all can be generally adopted in urban construction pipeline and fire-fighting or the like, if emergency situations need be when closing or opening import and export at once, the slow defective of gate valve speed will cause not right loss, certainly the Electric actuator that has also occurred at present replaces manually, but the cost that increases in addition is sometimes well beyond the not right loss of emergency situations.In existing valve, on valve, be provided with burglarproof lock had miscellaneous, but the valve of pull-rod type give and burglarproof lock is set has improved difficulty greatly, cost also improves thereupon.
At the Chinese invention patent application number be: 200910179231.2 have announced a kind of anti-theft quick-spin valve, it is to be provided with valve rod, flashboard and valve seat in valve body, it is that gate valve is stretched into installation from the latus rectum mouth, and valve body and flashboard are provided with first projection, second projection and the 3rd projection, valve rod is very easy to block in operating process, secondly it is provided with the track that spirals on valve rod, and the phenomenon of slide bar appears in the amplitude valve rod of this track that spirals greatly easily.
Summary of the invention
In order to solve the technical problem of the existence in above-mentioned, the invention provides a kind of pulling-down formula gate valve, characteristics are than the valve rod lifting efficient of conventional threads lifting soon more than at least 2 times, and the manufacture cost of the valve that lowers greatly.
