Description

Strut radiating type double seal double-flashboard gate valve
Technical field
The utility model relates to a kind of gate valve, especially a kind of radiating type double seal double-flashboard gate valve that struts.
Background technique
General in the market double-flashboard gate valve is not realized soft seal and the double sealing structure form that seals firmly and deposit simultaneously; sealability between flashboard and the sealing seat is limited; be difficult to satisfy the demand of high strength sealing occasion; when opening and closing gate valve; between flashboard and sealing seat, do not carry out good anti-wear protection; thereby shorten the working life that causes valve or sealability decline, and cause some more serious production accidents such as gas liquid leakage.
Summary of the invention
In order to overcome the defective of above-mentioned existing double-flashboard gate valve, the utility model provide a kind of sealing effect excellence and working life long strut radiating type double seal double-flashboard gate valve.
The utility model provides struts radiating type double seal double-flashboard gate valve, comprise handwheel, valve rod, valve body, sealing seat and two flashboards that left and right sides flashboard assembly parallel and that fix is formed, sealing seat is fixedly mounted in the valve body, flashboard can be installed in the valve body and with the sealing seat butt up and downly and cooperate, it is characterized in that: be provided with the piece of having a rest in the described flashboard, upper groove, under have a rest piece and low groove, the piece of having a rest on described also can be up and down at upper groove among being arranged in upper groove, have a rest on the described outside of piece is provided with and is the inclined-plane that comes closer from top to bottom, the inboard of described upper groove be provided with described on the have a rest upper groove inclined-plane of piece inclined-plane snap-fit, the end of piece of having a rest on described is fixedly connected by guide pin bushing and valve rod, on the have a rest the other end of piece flexibly connect by connecting ring and flashboard, the piece of having a rest under described is arranged among the low groove and is fixedly mounted on low groove, the bottom of described low groove is provided with and is outside open inclined-plane from top to bottom, described valve body bottom is provided with the flashboard support block that matches with flashboard, the outside of described flashboard support block is provided with the flashboard support block inclined-plane with described low groove inclined-plane snap-fit, and having a rest under described is provided with spring between piece and the flashboard support block.
The radiating type double seal double-flashboard gate valve that struts provided by the utility model, the piece of having a rest on it when flashboard moves down moves down until both in upper groove and tightens mutually, make it press close to sealing seat and flashboard strutted to both sides, flashboard contacts with the seal ring that sealing seat is inlayed and forms soft seal, contact and tighten mutually with the flashboard support block of valve body bottom when flashboard continues to move down into its low groove bottom, the flashboard support block further struts flashboard to both sides, form hard sealing between flashboard and the flashboard support block when soft seal is further strengthened, the combination of soft or hard double-sealing has improved the sealability of gate valve integral body greatly.And since flashboard arrive in the lowest order of bottom, flashboard and sealed member just reach the strongest gripping orientation, the wearing and tearing of sealed member in this process have been avoided to greatest extent, prolong the working life of gate valve, since under have a rest and be provided with spring between piece and the flashboard support block, when gate valve is opened, the spring that resets can quicken to open the required time of gate valve complementaryly, can shorten flashboard and draw close the process that resets to the centre, thereby reduce the friction between gate valve and valve body and gate valve and the sealing seat, also can play the effect in the working life that prolongs gate valve.
The utility model provides the improved radiating type double seal double-flashboard gate valve that struts, and described valve body bottom is provided with the limiting stopper that cooperates with the flashboard butt.Limiting stopper is used for accurately locating the following pan position of flashboard at valve body, avoids opening difficulty because of flashboard and flashboard support block card get wearing and tearing and the gate valve that tension causes.
The utility model further provides the improved radiating type double seal double-flashboard gate valve that struts, and is provided with radiating fin between described valve rod and the valve body.Radiating fin can be distributed the unnecessary heat that produces because of valve handle activity via valve body, thereby makes the temperature maintenance in the valve body reasonably interval at one.
Below in conjunction with drawings and Examples the utility model is described in further detail.
