Abstract
The invention provides an indication non-rising stem butterfly valve shaft fixture with an adjustable clearance. The indication non-rising stem butterfly valve shaft fixture comprises clamp baffle plates which are symmetrically arranged; a concave part is arranged on each clamp baffle plate; a cushion gasket is arranged in the concave part of each clamp baffle plate; the clamp baffle plate on the left side is fixed on a clamp positioning base; the clamp baffle plate on the right side is connected with a push rod through a clamp fixing rack; the push rod is fixed on an adjusting and positioning device through a push rod stabilization plate; an inner sleeve pipe is arranged in the adjusting and positioning device; one end of the inner sleeve pipe extends into the inner part of the push rod; the other end of the inner sleeve pipe is fixedly connected with an inner sleeve pipe fixing pin; the inner sleeve pipe fixing pin is connected with the inner sleeve pipe through occlusion tongs; an adjusting hand wheel is connected with the inner sleeve pipe fixing pin; and a fixture base is connected to the bottom part of the adjusting and positioning device. The indication non-rising stem butterfly valve shaft fixture has the advantages and positive effects that the structure is simple, and the assembly and positioning are rapid and convenient, so that the positioning and assembling work efficiency of the valve shaft of a non-rising stem butterfly valve can be greatly improved; the torsion is large, and the opening size is adjustable, so that the valve shaft and clamp plates are protected from damage during an assembly or disassembly process; and the indication non-rising stem butterfly valve shaft fixture is applicable to valves of multiple models.
Description
Technical field
The invention belongs to valve manufacture equipment technical field, especially relate to the adjustable instruction in a kind of gap dark bar butterfly valve shaft frock.
Background technology
The opening and closing element of inside screw nonrising stem type gate valve is flashboard, and the direction of motion and the flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete shut-down, can not make adjustments and throttling.Flashboard has two sealing surfaces, and two sealing surfaces of the most frequently used pattern slide valve form wedge shape, key groove is different with valve parameter.The flashboard of Wedge Gate Valves can make an entirety, is called rigidity flashboard; Also can make the flashboard that can produce micro-deformation, to improve its manufacturability, make up the deviation that sealing surface angle produces in process, this flashboard is called flexible disc.At present, valve shaft sectional fixture for inside screw nonrising stem type gate valve is rigid structure, a kind of fixture generally can only be applicable to a kind of valve of specification, in order to avoid because the off size valve fixture that causes is to the damage of valve, meet the requirement of producing clamp fixture, need to design a kind of moment of torsion large, the valve shaft frock of the inside screw nonrising stem type gate valve that opening size is adjustable.
Summary of the invention
The problem to be solved in the present invention is to provide the large and inside screw nonrising stem type gate valve valve shaft frock clamp that opening size is adjustable of a kind of moment of torsion.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the instruction that a kind of gap is adjustable dark bar butterfly valve shaft frock, wherein, comprise symmetrically arranged fixture gate, recess is established in described fixture gate, the recess of described fixture gate is provided with cushion pad, described left side fixture gate is fixed on fixture positioning seat, described right side fixture gate is connected with push rod by fixture fixed mount, described push rod is fixed on regulating positioning device by the firm plate of push rod, described regulating positioning device inside is provided with inner sleeve, described inner sleeve one end is deep into push rod inside, the other end is fixedly connected with inner sleeve steady pin, described inner sleeve outer wall is provided with screw thread, described inner sleeve steady pin is connected with inner sleeve by occlusion handgrip, described adjusting handle is connected with inner sleeve steady pin, tooling base is connected with bottom described regulating positioning device.
Further, described two fixture gate are symmetricly set in the both sides of two clamping plate of valve body.
Further, the firm plate of described push rod is provided with many reinforcement gussets.
Further, described tooling base and fixture positioning seat are fixed on the table.
The advantage that the present invention has and good effect are: structure is simple, installation location is efficient and convenient, greatly can improve the valve shaft location and installation operating efficiency of dark bar butterfly valve; Torsion is comparatively large and size openings is adjustable, protects valve shaft, clamping plate are not damaged, be applicable to Multiple Type valve and use in cargo handling process.
