Description
Technical field
The utility model relates to a kind of gate valve with the rotary type closure member, specifically the straight plate glasses valve of a kind of frame type.
Background technique
Be used for the fan-shaped glasses valve on the heavy caliber gas pipeline, left valve barrel and right valve barrel have been generally comprised, on right valve barrel, be provided with bellows and the traversing control mechanism of right valve seat, valve base chamber clamping at two valve bodies has and can carry out rotating straight shape valve plate around axostylus axostyle, and the two supports of axostylus axostyle is connected the upper end of two valve seats.In the working site, the left and right valve body of fan-shaped glasses valve is connected by flange with the heavy caliber gas pipe road junction on both sides respectively.Like this, gas pipe line draws, pushes because of stretching that rising-heat contracting-cold produced and active force such as distortion, just acted directly on the weak parts such as bellows of scalable motion on the glasses valve, and formed stress concentration point, caused the shortening in glasses valve working life by left and right valve body.Though the fan-shaped glasses valve that has is provided with the base of an affixed left and right valve body in the bottom, this has weakened the ill-effect power of gas pipe line to glasses valve to a certain extent, but because this affixed point only is to be positioned on the position of left and right valve body lower portion, therefore when gas pipe line reaches the active force of glasses valve or accumulates to a certain degree, just still there is the phenomenon of valve body breakage to take place, uses the just necessary repairing that stops production of enterprise.
In existing fan-shaped glasses valve, the traversing control mechanism of right valve seat is to be fixed with nut on left and right valve body respectively, and there is the screw rod of forward and reverse screw thread at the two ends that spin, centre.By forward and reverse rotation of screw rod, make right valve seat produce horizontal displacement movement, realize unclamping or clamp control thus to two valve base chamber valve plates.This traversing control mechanism is realized the clamping of two valve seats, so be called " unclamping fastening device " again because be the rotation application of force effect that utilizes the forward and reverse screw thread in screw rod two ends.And two valve base chambers have only three to clamp point of application of force, and this is the long-term overall tightness that is difficult to guarantee between valve seat and valve plate concerning the fan-shaped glasses valve of larger caliber.So the sealing difference is the another defective that the fan-shaped glasses valve of existing heavy caliber exists.
The model utility content
The purpose of this utility model just provides a kind of straight plate glasses valve of frame type of left and right valve body firm and reliable connection, to improve the working life and the sealability of glasses valve, ensures that the normal and safety of enterprise's production is carried out smoothly.
The utility model is achieved in that the straight plate glasses valve of frame type includes left valve barrel, right valve barrel, axostylus axostyle, straight shape valve plate, on right valve barrel, be provided with bellows and the traversing control mechanism of right valve seat, valve base chamber clamping at two valve bodies has and can carry out rotating straight shape valve plate around axostylus axostyle, institute's improvements are bottoms that two valve bodies are fixed in framework, and the two supports of axostylus axostyle is connected on the middle part cross bar of framework.
Like this, left and right valve body by with the fixedlying connected of framework, just can form an overall structure, constitute the straight plate glasses valve of a kind of frame type.The formation of this integrative-structure form makes this glasses valve with after the heavy caliber gas pipe line is connected, and can resist the active forces such as extruding, stretching and distortion that gas pipe line applies glasses valve effectively, has eliminated stress concentration point.Because the generation of above-mentioned action effect makes be prolonged effectively and improve the working life of the straight plate glasses valve of this frame type, to the ordinary production of enterprise, can play good promotion and guaranteeing role.The axostylus axostyle two supports is on the cross bar of the middle part of framework; both can guarantee of the normal revolution of straight shape valve plate at two valve base chambers of framework bottom; also correspondingly increased the flexural strength of framework; thereby further having strengthened the straight plate glasses valve opposing of this frame type gas pipe line stretches and draws or the reaction force of extruding etc. the working life of further having improved the straight plate glasses valve of this frame type thus.
The utility model also can be realized like this: the traversing control mechanism of right valve seat is installed on the framework of affixed right valve barrel one side.This mounting type is the basis that exists for framework, and be to be support with the framework, control the lateral displacement motion of right valve seat, thereby its active force is to make right valve seat press to straight shape valve plate, and can form a kind of clamping force, so the traversing control mechanism of right valve seat of the straight plate glasses valve of this frame type can be referred to as " compressing tripping-gear " again.This is the clamping force that relies on the framework, be better than obviously that forward and reverse thread screw rotation produces from clamping force, thereby can obviously improve the closing seam performance of glasses valve.
The utility model also can be realized like this: be provided with at least four and compress the control point on the traversing control mechanism of right valve seat, the control mechanism that compresses that compresses on the control point is sprocket wheel screw mechanism, worm-and-wheel gear or nut-screw mechanism.The multiple spot clamping force of Xing Chenging thus also is to be to rely on the pressuring action of implementing with the framework, and its action effect also obviously is better than 3 clamping forces of fan-shaped glasses valve, further improves the sealability of glasses valve.Owing to used this multi-point interlinked traversing control mechanism of right valve seat, a plurality of pressuring action points of valve base sealing have also just correspondingly been increased, thereby the sealability of the straight plate glasses valve of this frame type and sealing reliability can all be improved largely, overcome the drawback of fan-shaped glasses valve sealing difference.
