Abstract
The invention relates to a high-sealing right-angled pneumatic valve, which comprises a valve body and a cylinder body. An opening is formed in each of the bottom and sidewall of the valve body, and pipes are connected to the bottom and sidewall of the valve body. An opening is formed on the top of the valve body, and a connector is connected to the top of the valve body. The upper end of the connector is in sealing connection with the cylinder body. A valve head is arranged in the valve body. A piston rod is connected to the valve head, and sequentially penetrates through the connector and the cylinder body. A sealing element is sleeved on a section of the piston rod in the connector. A piston and a first spring are sleeved from bottom to top on the section of the piston rod in the cylinder body respectively. The upper end of the first spring is pressed against a top plate of the cylinder body. The high-sealing right-angled pneumatic valve is characterized in that: a plano-convex gasket, a V-shaped gasket, a V-shaped fluororubber gasket, a V-shaped gasket, a plano-concave gasket, a stainless steel flat gasket and a second spring are sleeved sequentially from bottom to top in the sealing element; and the upper end of the second spring is pressed against a round nut.

Description
Technical field
The present invention relates to a kind of pipeline valve, specifically be used for the right angle pneumatic valve with high sealing performance 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, all is provided with Sealing in the connecting body, 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.Yet; High leak tightness right angle pneumatic valve in use; Piston rod need be done and pump, and the relative valve body of Sealing is static, so 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 the pneumatic valve gas leakage of high leak tightness right angle, and shorten working life relatively.
Summary of the invention
The problem that the present invention will solve provides a kind of high leak tightness right angle pneumatic valve, adopts this high leak tightness right angle pneumatic valve, even if wearing and tearing appear in seal ring, also can not cause gas leakage, long service life.
For addressing the above problem, take following scheme:
High leak tightness of the present invention right angle 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, and is useful on the perforate that valve is installed on the connecting body 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, has center hole on the cylinder block top board, and piston rod passes from connecting body and cylinder block top board center hole 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 the piston and first 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 first spring and cylinder block top board offset.Be characterized in that 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 second spring from bottom to top successively on the piston rod between retainer ring and the round nut, second spring upper end offsets with round nut.Said plano-convex pad, V-arrangement pad, plano-concave pad all can adopt teflon to process.
Take such scheme, have the following advantages:
Because the inner seal ring that uses of the Sealing of high leak tightness of the present invention right angle 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, make increase the working life of high leak tightness right angle pneumatic valve.
