Abstract
The invention relates to a compact type electric valve positioner which comprises a coil, an armature penetrating into the coil, two first springs which are respectively arranged on the two sides of the same end of the armature, a baffle connected with the other end of the armature, a one-way amplifier with a nozzle right opposite to the baffle, a second spring, a third spring which is arranged between the first springs and the second spring and is with one end fixedly connected with a main lever, an auxiliary lever connected with the other end of the third spring, a cam mechanism connected with the auxiliary lever, and a membrane chamber connected between the cam mechanism and the one-way amplifier. The baffle and the second spring are symmetrically arranged relative to the main lever. The connection structure between the membrane chamber and the one-way amplifier and the connection structure between the one-way amplifier and the cam mechanism are both simple so as to be convenient to install, reduce the size of the valve positioner and enable an adjusting valve to adapt to different installation conditions.
Description
Technical field
The present invention relates to the valve positioner field, particularly a kind of compact type electrical equipment valve positioner.
Background technique
Existing valve positioner because, the linkage structure between film chamber and the Unidirectional magnifier is comparatively complicated, causes the valve positioner overall volume larger, and then causes the installation of modulating valve restricted.
Summary of the invention
The object of the invention provides a kind of compact type electrical equipment valve positioner.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of compact type electropneumatic valve positioner, it comprises coil, with the armature that is arranged in the described coil, two the first springs that are connected to the both sides of the same end of armature, the baffle plate that is connected with the other end of described armature, nozzle is over against the Unidirectional magnifier of baffle plate, be in symmetrical locational the second spring with described baffle plate about main lever, be arranged between the first spring and the second spring and the 3rd spring that an end and described main lever are fixedly connected, the auxiliary lever that is connected with the other end of described the 3rd spring, the cam mechanism that is connected with described auxiliary lever, be connected in the film chamber between described cam mechanism and the Unidirectional magnifier.
Optimize, described cam mechanism comprises the roller that is connected with described auxiliary lever, the feedback rod that is connected with described roller, the cam that is connected with described feedback rod same axis.
Owing to adopting technique scheme, the present invention has the following advantages: the linkage structure between film chamber of the present invention and the Unidirectional magnifier and Unidirectional magnifier linkage structure between cam mechanism is all comparatively simple, not only easy for installation, and reduced the volume of valve positioner, made modulating valve can be suitable for different installation conditionss.
