Abstract

The utility model discloses a bidirectional-flow pneumatic angle seat valve which comprises a valve body, a valve rod, a valve cover, a cylinder body, a cylinder cover and a piston, wherein arc angles are arranged in a valve body fluid passageway and located at corners of the valve body, a sealing body is connected with the lower end of the valve rod, a sealing ring is arranged in a groove at the lower end of the sealing body, a gasket is arranged on the lower portion of the sealing ring, and a sealing gasket is arranged between the valve body and the valve cover. Upper padding and lower padding are arranged between the valve rod and the valve cover in a sleeved mode, a compensation spring is arranged between the upper padding and the lower padding, and a disc spring is arranged at the upper end of the valve rod in the cylinder body. The disc spring is fixedly locked by a pressing nut, a copper sleeve is arranged between the valve rod and the pressing nut, and a reset spring is arranged between the cylinder body and the cylinder cover. The bidirectional-flow pneumatic angle seat valve has the advantages of being reasonable in design, reducing flowing resistance, greatly reducing energy loss of a pipeline system, reducing cost, being good in elasticity and convenient to maintain, improving work efficiency, and being good in sealing performance and long in service life.

Description

A kind of bidirectional flow pneumatic angle pedestal valve
Technical field
The utility model relates to valve, relates in particular to a kind of angle pedestal valve.
Background technique
At present, the straight-through form of the stop valve of producing on the market is more, and this valve design is reasonable inadequately, make local resistance big, reduced negotiability, improved the energy loss of pipe-line system greatly, secondly existing valve body structure is complicated, inner dead space is more, is easy to leave over residue, will influence working efficiency greatly like this.The model utility content
At the deficiencies in the prior art, the utility model provides a kind of bidirectional flow pneumatic angle pedestal valve.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of bidirectional flow pneumatic angle pedestal valve, comprise valve body, valve rod, valve gap, cylinder block, cylinder head and piston, be provided with arc round angle in the valve body fluid passage, arc round angle is located at the corner of valve body respectively, the valve rod lower end is connected with seal, be provided with seal ring in the groove of seal lower end, the bottom of seal ring is provided with packing ring, be lined with a sealing gasket between valve body and the valve gap, be with filler and following filler between valve rod and the valve gap, be provided with counterbalance spring between last filler and the following filler, the valve rod upper end of cylinder block inside is provided with the dish spring, use the gland nut fixing and locking on the described dish spring, be provided with copper sheathing between valve rod and the gland nut, be provided with Returnning spring between the cylinder block and head.
Described cylinder block and head is stainless steel.
Described piston is plastic materials.
The beneficial effects of the utility model: this model utility is reasonable in design, has reduced circulating resistance, greatly reduces the energy loss of pipe-line system, has reduced cost; Elasticity is better, maintenance is more convenient, has improved working efficiency; Good seal performance has improved its working life.
