Abstract

Provided is a sensing device of an electrically operated valve. A lead screw is connected on the valve, the other end of the lead screw is fixed, a gear is arranged on the lead screw, the gear is meshed with a gear connected with an output shaft of a motor, a lead screw nut is arranged on the lead screw, a sliding bar is arranged on one side of the lead screw, the sliding bar penetrates through the lead screw nut, two ends of the sliding bar are fixed to prevent the lead screw nut form rotating along with the lead screw, the upper portion of the lead screw nut and the lower portion of the lead screw nut are respectively provided with a limiting switch, and the limiting switches are connected with the motor. The sensing device of the electrically operated valve is suitable for valves which rotate in any number of turns, and the number of turns can be changed through the fact that relative positions of the two limiting switches are changed. Due to the fact that the gear transmission technology and the lead screw rotation technology are used, the sensing device of the electrically operated valve is reliable in operation and free of the influence of external interference.

Description

The sensing device of electric valve
Technical field
The utility model relates to a kind of valve, is the sensing device of electric valve specifically.
Background technique
The control section structure of the electric valve sensor on the market is complicated now, and corresponding cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of sensing device of electric valve, and it can solve multi-turn and count stopping automatically of rotating valve and unlatching problem, and is simple in structure, and control is reliable, and is with low cost.
The technical solution of the utility model is as follows:
A kind of sensing device of electric valve, it is to connect a leading screw on valve, the other end of leading screw is fixed, and adorns a gear on the leading screw, the gear engagement that this gear and motor output shaft connected; Establish feed screw nut on above-mentioned leading screw, establish the slip thick stick in leading screw one side, this slip thick stick passes the feed screw nut two ends and fixes, and rotates with leading screw to stop feed screw nut, and on the top of feed screw nut and the bottom bit switch of limiting respectively, above-mentioned switch connects motor.
Advantage of the present utility model is: 1, be applicable to the valve that rotates any number of turns, by changing the relative position of two limit switches, just can change the number of turns of rotation.2, owing to use gear transmission and leading screw rotating technique, this device reliable operation is not influenced by external interference.3, leading screw, feed screw nut and limit switch can use separately, control reciprocating device, as rolling shutter door, curtain etc.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Can be seen that by Fig. 1 this device is to connect a leading screw 2 on valve 9, the other end of leading screw is fixed, and adorns a gear 8 on the leading screw, gear 5 engagements that this gear and motor 6 output shafts are connected; Establish feed screw nut 3 on above-mentioned leading screw, establish slip thick stick 7 in leading screw one side, this slip thick stick passes the feed screw nut two ends and fixes, and rotates with leading screw to stop feed screw nut, and on the top of feed screw nut and the bottom bit switch 1,4 of limiting respectively, above-mentioned switch connects motor.
This device mainly is to utilize the leading screw principle to remove to touch normally closed switch, when the gear driven leading screw rotates, do not allow feed screw nut rotate, feed screw nut can only be done and vertically moves along with leading screw, and the main story of leading screw, counter-rotating can make feed screw nut do upper and lower moving along the leading screw direction.Utilize this to move disconnection and the connection that touches normally closed switch, the motor that the drive leading screw is rotated stops operating or opens rotation.
Working procedure: during electrical power, by transmission device feed screw nut is moved, when feed screw nut moves to limit switch 1, touch normally closed switch, motor stops operating, valve open.When motor flow through back current, the motor counter-rotating made valve do closing movement, and drive the leading screw rotation, feed screw nut is moved down, when feed screw nut touches the normally closed switch of limit switch 4, switch is disconnected, and motor stops operating owing to cutting off the power supply, at this moment valve closing.

Claims (1)
