Description

Dress formula cryogenic ball valve on-line maintenance device in one
Technical field
The utility model belongs to valve frock clamp field, especially a kind of upper dress formula cryogenic ball valve on-line maintenance device.
Background technology
At present, lack special equipment when upper dress formula cryogenic ball valve pipeline maintainance and assembling, mainly rely on manual operation, operate more difficult, operate more loaded down with trivial details, and when installing, pretightning force is not enough, causes less stable.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the upper dress formula cryogenic ball valve on-line maintenance device that a kind of structure is simple, reasonable in design, easy to operate, pressure is large.
The utility model solves its technical problem and takes following technical scheme to realize:
Dress formula cryogenic ball valve on-line maintenance device in one, it is characterized in that: comprise push rod, hinged block, nut, handle and connecting rod, push rod lower end is rotatablely equipped with a hinged block, push rod external wall of upper portion is shaped with screw thread and coaxial adjustment is provided with a nut, this nut is coaxially fixed with a hinged block outward, and push rod upper end is fixed with one handle; On the hinged block of both sides, push rod lower end, equal symmetry is hinged with the lower end of a connecting rod, and the upper end of this both sides connecting rod is all hinged with another connecting rod by hinged block, and all symmetrical hinge of connecting rod of this two upper lateral part is contained in hinged block both sides push rod being fixedly mounted with nut.
And this device is symmetrical rhombus four-bar linkage structure, and double leval jib length is identical.
Advantage of the present utility model and good effect are:
The utility model structure is simple, reasonable in design, easy to operate, has certain retractility, and pressure is large, improves efficiency of assembling, easy and simple to handle and easy accessibility.
Accompanying drawing explanation
Fig. 1 is practical view of the present utility model;
Fig. 2 is the utility model structural representation.
Mark representative in accompanying drawing: valve seat on the left of in the of 1; 2 maintenance units; 3 valve balls; Valve seat on the right side of in the of 4; 201 handles; 202 nuts; 203 push rods; 204 connecting rods; 205 hinged blocks.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Dress formula cryogenic ball valve on-line maintenance device in one, shown in accompanying drawing 2, comprise push rod 203, hinged block 205, nut 202, handle 201 and connecting rod 204, the agent structure of this maintenance unit is adjustable symmetrical rhombus four-bar linkage structure, double leval jib length is identical, concrete structure is: push rod lower end is rotatablely equipped with a hinged block, push rod external wall of upper portion is shaped with screw thread and coaxial adjustment is provided with a nut, this nut is coaxially fixed with a hinged block outward, push rod upper end is fixed with one handle, and this handle drives push rod rotates thus drives nut to move along push rod;
On the hinged block of both sides, push rod lower end, equal symmetry is hinged with the lower end of a connecting rod, the upper end of this both sides connecting rod is all hinged with another connecting rod by hinged block, the all symmetrical hinge of connecting rod on the top of these both sides is contained in hinged block both sides push rod being fixedly mounted with nut, during rotary handle, nut moves along push rod thus drives the link angle of both sides to change, and holds out against or loosens valve seat.
This structure adopts diamond structure, and this structure is convenient to stretch, and stability is high, easy and simple to handle.
The use step of this device is as follows:
(1) valve is in closed condition, is put into by maintenance unit 2 between left side valve seat 1 and right side valve seat 2;
(2) tighten handle, at this moment diamond structure can be elongated and hold out against valve seat, manual locking push rod, and device is fixed;
(3) demolition, installation valve ball 3 is complete, is unclamped by device, and diamond structure shrinks and shortens, and unclamps valve seat;
(4) finally pull down this device, complete maintenance operation.
