Description
Technical field
The utility model relates to a kind of pipeline valve, specifically is used for the pneumatic type valve at ell pipeline joint place.
Background technique
Right angle pneumatic valve in the market is made up of valve body, connecting body and cylinder mostly, and connecting body is the connected element between valve body and the cylinder, mainly plays the effect of piston rod guiding and cylinder support.And traditional right angle pneumatic valve directly is also used as connecting body with Sealing, and its tolerance intensity is low, when cylinder receives in air inlet moment or its outside when clashing into; Because discontinuity; Sealing is easy to generate distortion, and poor stability crackle can occur when serious; Thereby cause the gas leakage of cylinder or valve, working life is shorter.In addition,, when piston rod is longer, can swing, make and to reorientate when valve head and valve port are closed because the stationarity of Sealing is poor.
The model utility content
The problem that the utility model will solve provides a kind of right angle pneumatic valve, adopts this right angle pneumatic valve, and tolerance intensity is high, good stability, long service life; Swing when piston rod is longer, also can not occur, valve head and valve port need not resetting when closed.
For addressing the above problem, take following scheme:
A kind of right angle pneumatic valve of the utility model comprises valve body and cylinder block, and said valve body is a spherical cavity, opening is all arranged and be connected with body on its bottom and the sidewall, and the axis of two bodys is perpendicular.There is opening at the valve body top and is connected with connecting body, and connecting body upper end is with cylinder block and is tightly connected.Base plate is arranged at the connecting body bottom, is useful on the perforate that valve is installed on its sidewall.Be provided with valve head in the valve body, the body of valve head and valve body bottom is and is sealed and matched.The central position, upper end of valve head is connected with piston rod, all has center hole on connecting body base plate and the cylinder block top board, and piston rod passes from two center holes successively, and and the cylinder block top board between be and be slidingly matched.That section upper cover of piston rod in the connecting body has Sealing, makes to be sealed sliding movingly between connecting body and piston rod.Be with piston and spring from bottom to top respectively on that section piston rod in the cylinder block, be between piston and piston rod and be sealedly and fixedly connected, the upper end of spring and cylinder block top board offset.Be characterized in that said connecting body is up big and down small tubaeform, adopt flaring connecting body, can increase the intensity that cylinder is connected with valve body, improve stability.
The further improvement project of the utility model be said valve body with body between, between valve body and the connecting body all the mode through welding be connected, thereby can reduce manufacture cost.
The further improvement project of the utility model is that said valve head comprises valve head screw, valve block, cover plate and locking nut.Valve block and cover plate are discoid, and the diameter of cover plate is less than the diameter of valve block, and all have on it and the identical center hole of valve head screw outside thread cross-sectional sizes.There is circumferential groove at the edge of valve block upper-end surface center hole, and O type circle is arranged in the groove.The edge of valve block lower end surface has circumferential groove, and the flat gasket of annular is arranged in the groove.Said valve head screw passes the center hole of valve block and cover plate respectively, and through locking nut locking.When valve head was in the below limit position, flat gasket fell within on the tube wall of valve body bottom body.
The further improvement project of the utility model is that the upper end of said valve head screw links to each other with piston rod through wrist pin, is movably connected thereby make between valve head and the piston rod, can improve the sealing between the body of valve head and valve body bottom.
Adopt such scheme, have the following advantages:
Because a kind of right angle pneumatic valve of the utility model has adopted flaring connecting body between valve body and cylinder, its tolerance intensity is high, when discontinuity, is difficult for producing distortion, good stability, long service life.In addition,, when piston rod is longer, can not swing, make valve head and valve port closure need not to carry out resetting because the stationarity of tubaeform connecting body is better.
