Description

Compression ring for executing mechanism support under special condition

Technical Field

The utility model relates to the technical field of valves, in particular to a compression ring of an actuating mechanism bracket used under special conditions.

Background

At present, the connection modes of pneumatic actuating mechanisms and valves produced by various valve manufacturers are largely divided into two types. The lower flange of the bracket is fixedly pressed with the valve body valve cover through a round nut, and the lower flange of the bracket is fixedly connected with the valve body valve cover through a bolt and a nut.

Usually, each valve manufacturer supplies the valve and the executing mechanism in a matched manner, but the special situation is also provided, for example, when some old type valves need to be replaced with executing mechanisms, the original valve manufacturer does not reproduce the old type executing mechanism bracket; some customers purchase valves and actuators from two valve manufacturers, respectively. At this time, a problem arises in that the connection size of the valve and the actuator is not uniform, and the actuator cannot be connected to the valve.

Therefore, how to design a connection mechanism, which can effectively install and connect the unmatched actuating mechanism and the valve, becomes a problem to be solved by design.

Disclosure of Invention

The utility model aims to solve the technical problems that: in order to overcome the defects in the prior art, the utility model provides a compression ring for an actuating mechanism bracket under special conditions, which can be used for simply and efficiently connecting an actuating mechanism of an actuating mechanism and a valve with the valve.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a clamping ring that actuating mechanism support used under special circumstances for the valve gap of valve body and actuating mechanism's support flange joint installation under the support, support flange under with valve gap connection mounting end face open there is the hole, the hole in can dismantle and be equipped with the clamping ring, clamping ring internal diameter size and valve gap connection size cooperation.

In the above-mentioned scheme, when support lower flange and valve gap model mismatch, can design the clamping ring internal diameter according to the joint dimension of valve gap, after clamping ring and the support lower flange installation cooperation, the valve gap then is fixed with the clamping ring cooperation, has realized the valve gap and the connection of support lower flange is fixed, to the model mismatch occasion, only need correspond the clamping ring of different models of design can, need not to change support lower flange, effectively simplify the installation, reduce use cost.

Preferably, the inner hole of the lower flange of the bracket is internally provided with an internal thread, and the peripheral surface of the pressing ring is provided with an external thread matched with the internal thread.

Preferably, the inner hole of the lower flange of the bracket is a secondary step-shaped through hole, the compression ring is matched with the appearance of the secondary step-shaped through hole, the compression ring is in compression joint with the step surface of the diameter-variable position of the secondary step-shaped through hole, a plurality of threaded holes are annularly distributed on the step surface, and the compression ring and the lower flange of the bracket are in threaded fixation through screws in threaded connection with the threaded holes.

The pressing ring for the actuating mechanism bracket used under special conditions has reasonable structural design, can be used for supporting the connection and installation of the valve and the bracket lower flange when the valve is not matched with the bracket lower flange type, is convenient and quick in the installation process, effectively utilizes the existing valve and bracket resources, and saves the installation cost.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only those features which are relevant to the utility model, and orientation and reference (e.g., up, down, left, right, etc.) may be used solely to aid in the description of the features in the drawings. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the claimed subject matter is defined only by the appended claims and equivalents thereof.

Embodiment one:

a press ring for an actuator mount as shown in fig. 1 and 2 is a first embodiment of the present utility model. The valve cover for the valve body is connected and installed with the lower flange 1 of the bracket of the actuating mechanism.

An inner hole is formed on the end surface of the support lower flange 1, which is connected with the valve cover. The inner hole is internally provided with an internal thread, and the outer circumferential surface of the compression ring 2 is provided with an external thread matched with the internal thread.

When in actual use, the internal thread can be machined on the lower flange 1 of the bracket in advance, the compression ring 2 with the proper inner diameter is selected according to the size of the valve cover, and the inner diameter size of the compression ring 2 is matched with the connecting size of the valve cover. And then the compression ring 2 is fixedly arranged in the inner hole in a threaded manner, the fixation of the support lower flange 1 and the compression ring 2 is realized, and finally the valve cover and the compression ring 2 are normally connected and fixed, so that the connection and fixation of the valve cover and the support lower flange 1 can be completed. The valve cover and the support lower flange 1 model mismatch occasion are met, the press rings 2 with different models are only required to be correspondingly designed, the support lower flange 1 is not required to be replaced, the installation is effectively simplified, and the use cost is reduced.

Meanwhile, by adopting the compression ring 2 provided by the application, the same size as the extension height of the valve rod is required to be ensured, and the strength of the support lower flange 1 when the compression ring 2 is applied meets the use requirement through calculation, otherwise, the support still needs to be redesigned.

Embodiment two:

a compression ring used in special cases for an actuator mount as shown in fig. 3 and 4 is a second embodiment of the present utility model. The difference compared with the first embodiment is that the inner hole and the compression ring 2 are installed in different ways.

Specifically, the hole of support lower flange 1 is second grade step form through-hole, clamping ring 2 and second grade step form through-hole appearance adaptation, and clamping ring 2 crimping on the step face of the reducing position of second grade step form through-hole, and annular even interval distributes has eight screw holes on this step face, clamping ring 2 and support lower flange 1 pass through screw 3 screw-thread fit with screw hole cooperation threaded connection.

Similarly, on the basis of the existing support lower flange 1, a secondary step-shaped through hole is machined, and the compression ring 2 is correspondingly designed. When the valve cover is used, the compression ring 2 with the corresponding inner diameter is selected according to the installation requirement of the valve cover, the valve cover is locked and fixed on the lower flange 1 of the support through the screw 3, and then the valve cover is fixedly connected with the compression ring 2, so that the lower flange 1 of the support is fixedly connected with the valve cover.

With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
