Abstract

The utility model relates to a valve controller. The valve controller comprises a valve support, a controller shell, a dial, a single-sided cam and an elastic contact. The controller shell is coaxially installed at the upper end of a valve rod of the valve support, a transparent display window is coaxially installed at the upper end of the controller shell, the dial inside can be directly observed through the transparent display window, and an inwardly-convex arrow is formed on the portion, at one radial end of the display window, of the controller shell; the single-sided cam is coaxially installed on the portion, below in the dial, inside the controller shell, and the elastic contact is arranged on the portion, on one radial side of the single-sided cam, inside the controller shell and makes contact with the side wall of the single-sided cam to be driven by the single-sided cam. Because the valve rod is matched with a locking disc, accurate control over the opening angle is facilitated; the valve controller is simple in structure and easy to control and can help operating personnel to master flow rate conditions more easily; besides, valve components are easy to install and long in service life.

Description

Valve positioner

Technical field

The utility model belongs to valve field, especially a kind of valve positioner.

Background technique

Use at engineering pipeline transportation art valve is very extensive, the basic structure of valve is co-axial seal setting-in valve seat in valve body now, valve rod is radially installed on valve body, on valve rod in valve body, be fixedly mounted with valve plate, valve plate coordinates with valve base sealing, thereby valve plate rotation or movement under the driving of valve rod open and close the runner in valve seat; Valve body is shaped with the flange plate being connected with pipeline outward.

Present valve positioner structure is comparatively complicated, a plurality of rotating disks such as open and close need to be installed, the plurality of rotating disk is corresponding electromagnetic induction switch respectively, the accessory of valve is more, circuit is installed also comparatively loaded down with trivial details, and existing sign arrow and dial be respectively and install, easily to damage, working life is shorter.

Model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of valve positioner of reasonable in design, simple in structure, easy to operate, long service life is provided.

The utility model solves its technical problem and takes following technological scheme to realize:

A kind of valve positioner, it is characterized in that: comprise valve rack, controller housing, dial, one-sided cam and resilient contact, valve rod upper end on valve rack is coaxially installed with controller housing, the transparent indicator window of the coaxial installation in this controller housing upper end, see through this indicator window and observe directly inner dial, indicator window is radially shaped with the arrow of a convex on the control shell of one end; In the controller housing of dial below, be coaxially installed with an one-sided cam, this one-sided cam is radially provided with a resilient contact in the controller housing of a side, the sidewall contact of this resilient contact and one-sided cam by this one-sided actuated by cams.

And, on described dial, be radially shaped with out, 50,100 and close a plurality of gears.

And described controller housing bottom is also provided with manual control handle, this manual control handle is connected with a drive motor.

Advantage of the present utility model and good effect are:

1, the utility model is simple in structure, adopts valve rod end construction to replace sign arrow, not fragile, and the integrative-structure of valve rod own can guarantee to indicate rotation angle more accurate, and simplified structure accessory, simplifies installation steps.

2, the utility model valve plate and valve rod are fixedly mounted with and can regulate by trimming bolt, guarantee that the indication of valve plate and valve rod end is accurate in the same way, and indication is accurate, thereby guarantee that the angle control accuracy of valve is high.

3, valve rod of the present utility model coordinates with lock collar, is convenient to accurately control opening angle, simple in structure, easily controls, and helps operator to be more prone to grasp flow situation, and simple in structure, and the installation of valve part is simple, long service life.

Fig. 1 is structural front view of the present utility model;

Fig. 2 is the partial sectional view (removing dial) of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing and 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.

A kind of valve positioner, comprise valve rack 2, controller housing 4, dial 3, one-sided cam 6 and resilient contact 7, valve rod upper end on valve rack is coaxially installed with controller housing, the transparent indicator window of the coaxial installation in this controller housing upper end, see through this indicator window and observe directly inner dial, on this dial, be radially shaped with out, 50,100 and a plurality of gears such as pass; Indicator window is radially shaped with the arrow 5 of a convex on the control shell of one end.

In the controller housing of dial below, be coaxially installed with an one-sided cam, this one-sided cam is radially provided with a resilient contact in the controller housing of a side, the sidewall contact of this resilient contact and one-sided cam by this one-sided actuated by cams.

For the ease of controlling, described controller housing bottom is also provided with manual control handle 1, and this manual control handle is connected with a drive motor.

Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
