Description
Technical field
The present invention relates to a kind of pipeline valve, specifically be 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, thereby makes between valve body and connecting body, all be between connecting body and cylinder and be sealed and matched.Traditional Sealing mostly its with inwall that piston rod contacts on machined grooves, O type circle is installed in groove because the gap between bottom portion of groove and the piston rod is less than the diameter of O type circle, thereby after installation, realize sealing effect through extruding to O type circle.Said structure has following shortcoming:
1. because the tolerance intensity of Sealing is low, when cylinder receives in air inlet moment or its outside when clashing into, because discontinuity, connecting body is easy to generate distortion, even crackle occurs, thereby causes cylinder or valve gas leakage, and working life is shorter.And the stationarity of Sealing is poor, when piston rod is longer, can swing, and makes need reorientate when valve head and valve port are closed.
2. the right angle pneumatic valve in use; Piston rod need be done and pump; And the relative valve body of Sealing is static; Therefore can produce bigger frictional force between the O type circle in piston rod and the Sealing, long-time use will cause the circle heavy wear of O type and cause right angle pneumatic valve gas leakage, further shorten the working life of right angle pneumatic valve.
Summary of the invention
The problem that the present invention will solve provides a kind of right angle pneumatic valve, the good airproof performance of this right angle pneumatic valve, and working life is longer, and valve head and valve port need not to carry out resetting when closed.
For addressing the above problem, take following scheme:
Right angle of the present invention pneumatic valve 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, and Sealing comprises filled column, and the filled column upper end is through the round nut that has been threaded, and the filled column lower end is fixedly connected with retainer ring.On round nut and the inwall that piston rod contacts circumferential groove is arranged, the leather cup of annular is arranged in the groove.The Sealing outside is with O type circle, is sealed and matched thereby make to be 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.It is characterized in that: said connecting body is up big and down small tubaeform; Said filled column inside is with plano-convex pad, V-arrangement pad, V-arrangement fluororubber pad, V-arrangement pad, plano-concave pad, stainless steel flat gasket and spring from bottom to top successively on the piston rod between retainer ring and the round nut, the spring upper end offsets with round nut.Said plano-convex pad, V-arrangement pad, plano-concave pad all can adopt teflon to process.
Further improvement project of the present invention 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.
Further improvement project of the present invention 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 corresponding 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 body tube wall of valve body bottom connection.
The upper end that further improvement project of the present invention is 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.
In addition, be processed with circumferential groove, O type circle is arranged in the groove, in the outside of groove some screws are arranged on the connecting body, be fixed together through screw and nut between said cylinder block and connecting body in the upper-end surface of said connecting body.
Adopt such scheme, have the following advantages:
1. because right angle of the present invention pneumatic valve has adopted flaring connecting body between valve body and cylinder, its tolerance intensity is high, when discontinuity, is difficult for producing distortion, long service life.And the stationarity of tubaeform connecting body is good, when piston rod is longer, also can not swing, and makes valve head and valve port closure need not to carry out resetting.
2. owing to the inner seal ring that uses of the Sealing of right angle of the present invention pneumatic valve is made up of plano-convex pad, V-arrangement pad, V-arrangement fluororubber pad, V-arrangement pad, plano-concave pad; And there is spring its top, when wearing and tearing appear in the position that seal ring contacts with piston rod, relies on the extruding of spring force; Make seal ring further compress and abut plunger pin; Can continue to play the effect of sealing, thereby avoid the generation of gas leakage, further increase the working life of right angle pneumatic valve.
