Abstract

A resistance automatic regulating valve relates to the structural improvement of a checking-valve. The utility model, being directed to the existing situation, provides a simply-structured resistance automatic regulating valve able to avoid making noises. The utility model comprises a valve body (2). The essential structure lies in that: the pipeline (1) of the valve body (2) is provided with a valve core (3); bolts (5) on the valve core (3) is through the valve cover connected with a nut screw (7) on a gear frame (6) and an anchor pin (12) in the guide groove (11) of the internally-driven sleeve (13) of the gear frame (6); the internally-driven sleeve (13) is fixed on the shaft (14) of an electrical motor (15); the bolts (5) are provided with stops (8) and stop disks (9) of stops (10); a control meter (16) is arranged on the gear frame (6) at the side.

Description

The resistance automatic regulating valve

Technical field:

The utility model relates to the improvement of stop valve structure.

Background technique:

Present stop valve is mainly with the opening or end of valve gap control valve, especially less with the distance of blind hole when valve gap, be valve unlatching than hour, because of water is bent into 90 ° of operations twice in valve, will produce ear-piercing noise.

The model utility content:

The utility model is exactly at existing situation, and a kind of avoid producing noise, resistance automatic regulating valve simple in structure are provided.

The utility model adopts following technological scheme: the utility model comprises valve body, its structure outline is to have spool on the pipeline of valve body, bolt on the spool links to each other with the connecting pin in the guide groove of drive sleeve in the nut on the gear frame, the gear frame respectively by valve gap, drive sleeve is fixed on the motor shaft, have the position-arresting disk that can touch gear frame upper limit device on the bolt, the side of gear frame is provided with controller.

The beneficial effects of the utility model:

The utility model is with the moving up and down of Electric Machine Control spool, reach open, by the water route, therefore, in the running of this spool, can not produce noise; And member is few, and simple, is easy to make;

In addition, the utility model is provided with controller, and temperature that can be by setting, flow, pressure etc. are promptly controlled the unlatching and the flow size of this valve to motor operation control, have brought very big convenience to the user.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

The utility model comprises valve body 2, has spool 3 on the pipeline 1 of valve body 2, bolt 5 on the spool 3 links to each other with the connecting pin 12 in the guide groove 11 of drive sleeve 13 in the nut on the gear frame 67, the gear frame 6 respectively by valve gap 4, drive sleeve 13 is fixed on 15 14 in the motor, have the position-arresting disk 9 that can touch gear frame 6 upper limit devices 8, snubber 10 on the bolt 5, the side of gear frame 6 is provided with controller 16.

Below in conjunction with course of action of description of drawings:

When this valve ended: motor 15 obtained the instruction running, just driving drive sleeve 13 rotates, drive sleeve 13 drives bolt 5 by connecting pin 12 and rotates synchronously, the bolt 5 just nut 7 on the gear frame 6 moves downward, be that valve gap 4 moves downward thereupon, until closed conduct 1, meanwhile, position-arresting disk 9 touches snubber 8, and motor 15 shuts down;

When this valve was opened, then motor 15 obtained instruction, motor 15 counter-rotatings, and other parts and above-mentioned reverse movement, until opening pipeline 1, position-arresting disk 9 touches snubber 10, and motor 15 shuts down.

Claims

1. resistance automatic regulating valve, comprise valve body (2), it is characterized in that having spool (3) on the pipeline (1) of valve body (2), bolt (5) on the spool (3) links to each other by the connecting pin (12) in the guide groove (11) of the nut (7) on the same respectively gear frame of valve gap (4) (6), the interior drive sleeve of gear frame (6) (13), drive sleeve (13) is fixed on motor (15) axle (14), have the position-arresting disk (9) that can touch gear frame (6) upper limit device (8), snubber (10) on the bolt (5), the side of gear frame (6) is provided with controller (16).
