By adopting technique scheme, conflict and be connected with valve body in gland one end that valve body is provided with, the other end is conflicted and is connected with valve seat, because gland shape is fixed, valve seat can not rocked easily, and what make that valve seat contacts with valve body is tightr, better tightness, elastic component one end can be fixed on gland simultaneously, makes the setting of gland can not increase the volume of valve body.
Of the present utility modelly further be set to: on described valve seat, be also provided with and on valve seat, be also provided with the resettlement groove of conflicting and being connected with spheroid.
By adopting technique scheme, the one end contacting with spheroid at valve seat is also provided with the resettlement groove of an indent, and resettlement groove has certain radian, and the area of contact of spheroid and resettlement groove is increased, increase the sealing between spheroid and valve seat, made safety check there is good sealing effect.
Of the present utility modelly further be set to: described annular protrusion cross section shape triangular in shape.
By adopting technique scheme, annular boss forms cross section shape triangular in shape, makes cross section more tight with contacting of groove, makes valve seat tightr with contacting of valve body, makes better tightness, and is difficult for mobile
Of the present utility modelly further be set to: described valve seat is made by teflon.
By adopting technique scheme, teflon has the good advantage such as high temperature resistant, low temperature resistant, corrosion-resistant, makes having of valve seat longer working life, and the not yielding sealing that makes of valve seat is more outstanding simultaneously.
The utlity model has following advantage: valve seat and valve body on valve body are realized clamping, make the valve body that is arranged so that of valve seat there is good sealing, extended the working life of valve body simultaneously.
