Technical field
The utility model relates to a kind of improvement of gate valve, and particularly a kind of moment of torsion of closing the rubber flashboard is little, and the good gate valve of sealability.
Background technique
As shown in accompanying drawing 1-4, traditional gate valve adopts circumferential sealing usually, and traditional gate valve comprises valve body 1, rubber flashboard patchhole 3, rubber flashboard 4, guide rail 5, guide groove 6; Be provided with valve channel 2 in described valve body 1; Described rubber flashboard patchhole 3 is arranged on valve body 1, is provided with in couples guide rail 5 on the inwall of described rubber flashboard patchhole 3; The both sides of described rubber flashboard 4 are provided with respectively guide groove 6; The middle part of the end face of the lower edge of described rubber flashboard 4 is provided with groove; The two ends of described groove are provided with sealed muscle 7; When rubber flashboard 4 inserted rubber flashboard patchhole 3 along guide rail 5, guide groove 6 inserted on guide rail 5; With the top of defeating rubber flashboard 4, can make the inwall close contact of sealed muscle 7 and valve channel 2, realize partition, sealing to valve channel 2.The curve parameter of described sealed muscle and the inwall of valve channel match, and when the rubber flashboard presses down, realize sealing.The shortcoming of this sealing configuration is: 1, sealing is unreliable, when particularly fluid is in low pressure or high pressure, easily leaks; Need to firmly press down when 2, closing, also namely operate moment of torsion and increase, cause the practical quality of valve to descend.
The model utility content
The utility model purpose is to provide a kind of moment of torsion of closing the rubber flashboard little in order to overcome the deficiencies in the prior art, and the good gate valve of sealability.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gate valve comprises valve body, rubber flashboard patchhole, rubber flashboard, guide rail, guide groove; Be provided with valve channel in described valve body; Described rubber flashboard patchhole is arranged on valve body, is provided with in couples guide rail on the inwall of described rubber flashboard patchhole; The both sides of described rubber flashboard are provided with respectively guide groove; The middle part of the end face of the lower edge of described rubber flashboard is provided with groove; The sidepiece of the lower edge of described rubber flashboard is provided with the supercharging groove; When the rubber flashboard inserted rubber flashboard patchhole along guide rail, guide groove inserted on guide rail; When with the top of defeating the rubber flashboard, can make the two ends of described groove and the inwall close contact of valve channel, realize the sealing to valve channel.
Preferably, the opening of described supercharging groove be arranged in parallel towards the medial axis with valve channel.
Preferably, the two ends of described groove are provided with lip shape sealed muscle.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The described gate valve of the utility model scheme, the two ends lip shape sealed muscle of described groove makes the Adapter Property of rubber flashboard and valve channel good, the sidepiece of the lower edge of described rubber flashboard is provided with the supercharging groove, even also sealed valve body passage well under the fluid low-pressure state, sealability under the fluid high-pressure state is better, and the operation moment of torsion is minimum.

Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 5-6 is the described a kind of gate valve of the utility model scheme, comprises valve body 1, rubber flashboard patchhole 3, rubber flashboard 14, guide rail 5, guide groove 16; Be provided with valve channel 2 in described valve body 1; Described rubber flashboard patchhole 3 is arranged on valve body 1, is provided with in couples guide rail 5 on the inwall of described rubber flashboard patchhole 3; The both sides of described rubber flashboard 14 are provided with respectively guide groove 16; The middle part of the end face of the lower edge of described rubber flashboard 14 is provided with groove, and groove two ends arrange lip shape sealed muscle (seeing Fig. 6); The sidepiece of the lower edge of described rubber flashboard 14 is provided with supercharging groove 18; The opening of described supercharging groove 18 is towards the setting consistent with the valve channel medial axis, when valve body passage 2 to obtain larger hydrodynamic pressure; When rubber flashboard 14 inserted rubber flashboard patchhole 3 along guide rail 5, guide groove 16 inserted on guide rail 5; When with the top of defeating rubber flashboard 14, can make the lip shape sealed muscle that arranges on the two ends of described groove as the inwall close contact of sealed department 17 with valve channel 2, realize the sealing to valve channel 2.
Working principle of the present utility model is: during the gate valve closing operation, as long as the sealed department 17 of the lower edge of rubber flashboard 14 contacts with the inwall one of valve channel 2, fluid is obstructed, hydrodynamic pressure begins to rise, and hydrodynamic pressure just produces a downward thrust in supercharging groove 18, sealed department 17 is pressed on the inwall of valve channel 2, this thrust is along with the increase of hydrodynamic pressure increases, hydrodynamic pressure is larger, and sealed department 17 is pressed tightlyer, and sealing effect just better.
The described gate valve of the utility model scheme, the two ends lip shape sealed muscle of described groove makes the Adapter Property of rubber flashboard and valve channel good, the sidepiece of the lower edge of described rubber flashboard is provided with the supercharging groove, even also sealed valve body passage well under the fluid low-pressure state, sealability under the fluid high-pressure state is better, and the operation moment of torsion is minimum.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
