The specific implementation mode is as follows:
the utility model will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 5, the manual-automatic integrated valve actuator with a limiting function of the present invention includes a housing 1, a limiting seat 2, a limiting mandrel 3, a first spring 4, a limiting cover 6 and an actuating motor 7.
The first spring 4 is sleeved on the outer side of the limiting mandrel 3, the limiting cover 6 is fixed on the shell 1, the lower end of the first spring 4 abuts against the limiting seat 2, and the upper end of the first spring abuts against the limiting cover 6. The execution motor 7 is fixedly connected with the shell 1, and a motor shaft of the execution motor 7 extends into the limiting mandrel 3 and drives the limiting mandrel 3 to rotate.
The limiting mandrel 3 comprises an upper shaft body 31, a lower shaft body 32, a bolt 33 and a second spring 34, wherein the upper shaft body 31 is fixedly connected with a motor shaft of an actuating motor 7, the bolt 33 is semi-cylindrical, the upper end of the bolt 33 is movably inserted into the upper shaft body 31, and the lower end of the bolt 33 is inserted into the lower shaft body 32. The second spring 34 is sleeved on the pin 33 and disposed between the upper shaft 31 and the lower shaft 32.
On the outer wall of axis body 32 was located down to the protruding 300 of second, be equipped with micro-gap switch on the outer wall of last axis body 31 and dial tooth 301, when executing motor 7 drive spacing dabber 3 rotated, micro-gap switch dials tooth 301 and is used for touching the micro-gap switch in the casing 1, then control opening and shutting of executing motor 7.
When the valve is used, the limiting seat 2 is fixedly connected with a valve seat of the executed valve, and a valve rod of the executed valve extends into the lower shaft body 32. When needing electronic driven valve, open actuating motor 7 can, actuating motor 7 closes the back, through the cooperation of second spacing groove 22 with second arch 300, avoids actuating motor 7 to take place the phenomenon of overrotation because of inertia.
When the valve needs to be opened and closed manually, the shell 1 is pressed downwards to drive the actuating motor 7 and the upper shaft body 31 to move downwards integrally, so that relative movement occurs between the limiting seat 2 and the shell 1 and between the actuating motor 7 and the lower shaft body 32. First spacing arch 21 breaks away from first spacing groove 11 this moment, after first spacing arch 21 breaks away from first spacing groove 11, it rotates together to rotate casing 1 and drives actuating motor 7, actuating motor 7's motor shaft drives whole spacing dabber 3 and rotates together (when the interlock makes the actuating motor outage each other between the inside gear of valve actuating motor, actuating motor's motor shaft can not make its rotation with manual pulling), then realize the manual operation to the valve, in the manual operation process (be spacing dabber 3 by the manual rotation in-process promptly), the rotation range of lower axis body 32 receives the restriction of second spacing groove 22, avoid the phenomenon of overrotation.
In the utility model, the depth of the first limiting groove 11 is less than that of the second limiting groove 22, and when the shell 1 is pressed downwards to enable the first limiting bulge 21 to be separated from the first limiting groove 11, the second bulge 300 is still arranged in the second limiting groove 22.
The limiting seat 2 is of a step seat structure with a big circular part and a small circular part, and the first limiting bulge 21 is arranged on the outer wall of the big circular part. In order to facilitate the fixed connection of the limiting seat 2 and the valve seat of the actuated valve, a clamp spring groove 23 is arranged on the outer wall of the small circular part. A clamp spring is clamped in the clamp spring groove 23, so that the limiting seat 2 is fixedly connected with the valve seat of the actuated valve.
In the utility model, a stepped hole 10 with a large hole part and a small hole part is arranged on a shell 1, and first limiting grooves 11 are symmetrically arranged on the stepped surface of the stepped hole 10. The inner wall of the large hole part of the stepped hole 10 is provided with a vertically arranged limiting rib 12, and the inner wall surface of the limiting rib 12 and the inner wall surface of one side of the first limiting groove 11 are positioned in the same plane A. Set up spacing muscle 12, after first spacing arch 21 breaks away from first spacing groove 11, spacing muscle 12 is spacing when further carrying out the motion to spacing seat 2.
When the pure electric actuator without manual operation is limited, only two limiting grooves which are symmetrically arranged are arranged on the inner hole wall of the shell 1, as shown in fig. 6.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the utility model and these modifications should also be considered as the protection scope of the utility model.
