Abstract
The utility model relates to a double valve plate abrasion-proof valve door. The double valve plate abrasion-proof valve comprises a valve body, a valve port on the valve body, a valve plate cooperated with the valve port, wherein the valve plate comprises a left valve plate and a right valve plate which are fixedly connected with each other by a connection piece and the connection piece is connected with a linear actuator; the left valve plate and the right valve plate respectively cooperate with the left valve port and the right valve port; the connection piece is an elastic connection piece and comprises a sleeve and two ends of the sleeve is in plug-in connection with the left valve plate and the right valve plate; a compression spring is arranged in the sleeve and two ends of the compression spring respectively compact the left valve plate and the right valve plate. The double valve plates ensure the seal reliability and simultaneously the compression spring ensures the close fit between the valve plate and the valve port. The seal effect is not reduced along with the abrasion of the grinding surface when the valve plate and the valve port are on the line and the effect of back pressure change on the seal is conquered and the material is prevented from entering into the two sealing surfaces.
Description
Technical field
The utility model is a kind of bivalve plate wearable valve.
Background technique
At present, problem such as it is easily aging that known valve mechanism ubiquity poor sealing performance, Sealing, and switching motion not wear-resisting, valve is unreliable, thus needing causing often overhauls and safeguards valve.For guaranteeing the sealability of valve, need change Sealing continually, so maintenance cost is very high, and has increased working strength of workers, cause the waste of manpower and resource.
Summary of the invention
Carry cutting-off valve effectively bidirectional bearing and switch deficiency not in place in order to overcome present strength, the utility model provides a kind of bivalve plate wearable valve, self-locking can realize bidirectional bearing behind this valve closing, valve pocket is open but volume is little, material can not stop and harden, and valve plate is flexible movements in valve pocket, and single valve plate cooperates with valve seat, the precision height, good airproof performance.
The utility model is realized by following technical measures: a kind of bivalve plate wearable valve, it comprises the valve port that is provided with on valve body, the valve body, the valve plate that cooperates with valve port, described valve plate comprises left valve plate and right valve plate, fixedly connected between described left valve plate and the right valve plate by link, described link is connected with straight line executing mechanism, and described left valve plate and right valve plate cooperate respectively at left valve port and right valve port; Described link is a Flexible Connector, and it comprises sleeve, and the two ends of described sleeve are connected with right valve plate plug-in mounting respectively at left valve plate, are mounted with pressure spring in the described sleeve, and the two ends of described pressure spring compress left valve plate and right valve plate respectively.The utility model reaches the reliability of sealing by the sealing of bivalve plate, the effect of pressure spring simultaneously can guarantee closely cooperating of valve plate and valve port, be valve plate and valve port can not influence sealing effect at work along with the wearing and tearing of abradant surface and can overcome because of the back pressure variation to the influence that seals and prevent that material from entering two sealing surfaces.
In order to increase wear resistance, further improvement of the utility model also has, and a side that cooperates with valve plate on the above-mentioned valve port inwall is inlaid with the wear-resistant seal ring, and described seal ring cooperates with valve plate realizes sealing.Wherein seal ring can be changed, and can adopt high-abrasive materials such as alloy carbon steel or ceramet, increases its wear resistance, prolongs its working life.
Concrete characteristics of the present utility model also have, and also are provided with the side valve body between above-mentioned valve body and the seal ring.
The beneficial effect of this programme can learn that straight line executing mechanism drives the motion of bivalve plate, realizes the keying of valve port according to the narration to such scheme; The sealing of bivalve plate reaches the reliability of sealing, the effect of pressure spring simultaneously can guarantee closely cooperating of valve plate and valve port, be valve plate and valve port can not influence sealing effect at work along with the wearing and tearing of abradant surface and can overcome because of the back pressure variation to the influence that seals and prevent that material from entering two sealing surfaces; Seal ring can be changed, and can adopt high-abrasive materials such as alloy carbon steel or ceramet, increases its wear resistance, prolongs its working life.
