Abstract

The utility model relates to a portable handheld valve opening/closing device, which comprises a motor, a first-stage speed reducer, a second-stage speed reducer, an output pivoted arm and a force arm rod. The motor is a direct current motor, the first-stage speed reducer is driven by an output shaft of the motor, then the second-stage speed reducer is driven by an output shaft of the first-stage speed reducer, and an output shaft of the second-stage speed reducer is connected with the pivoted arm; and the force arm rod is coaxially fixed and mounted on the casing of the motor through a mounting plate, a handheld ring is fixed and mounted on the first-stage speed reducer, and a power supply input device is further mounted on the force arm rod. The opening/closing device has a small overall structure and is convenient to carry; the two stage speed reducers driven by the motor are adopted to open or close a valve, so that the starting torque is large, the opening/closing speed is high, and the starting is reliable; and the portable handheld valve opening/closing device can be suitable for valve opening/closing in various occasions and narrow zones, and has a wider applicable range.

Description

A kind of portable hand-held immediate action valve opening/closing device

Technical field

The utility model belongs to valve field, relates to the keying of valve, especially a kind of portable hand-held immediate action valve opening/closing device.

Background technique

, intersection intensive at the harbour tank compartment pipeline under the situation that exterior power (electricity, gas) is destroyed, must be carried out emergency cut-off to control valve.

Overcoming the above problems the main manual gear speed reducer that is carried on valve original (electricity, the gas) actuating device that leans at present closes; But this device requires great effort in the operation of large bore valves, time-consuming; And can not contact when being heated at special operation condition, therefore might cause greater loss.

Through retrieval, there be not to find the publication document relevant with present patent application yet.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of existing technology, provides a kind of removable portable immediate action valve urgent start-stop device, and that this device has is simple to operate, keying speed fast, safety, labour-saving characteristics.

The purpose of the utility model is achieved in that

A kind of portable hand-held immediate action valve opening/closing device; It is characterized in that: constitute by motor, one-level retarder, two stage reduction gear, output pivoted arm and arm bar; Motor output shaft connects the one-level input shaft of speed reducer; The output shaft of one-level retarder connects the input shaft of two stage reduction gear again, and the output shaft of two stage reduction gear connects pivoted arm; Coaxially on the casing of motor install arm bar, on the one-level retarder, be fixed with a hand-held ring, a power supply loader also is installed on arm bar through mounting plate.

Said pivoted arm is processed four directions or hexagonal shaped shape.

Said motor is a direct current generator.

The advantage and the good effect of the utility model are:

1, this opening/closing device overall structure is small and exquisite, is easy to carry, and does not directly contact with valve, can be suitable for the valve opening and closing of various occasions and narrow zone, and Applicable scope is wider.

2, this opening/closing device adopts motor-driven double reduction gear to carry out valve opening and closing, and starting torque is big, and keying speed is fast, starts reliable.

3, this opening/closing device also can adopt fork to implement artificial the keying when not having electricity, and it is big to start the arm of force, has improved starting torque thus, time saving and energy saving.

Fig. 2 is the plan view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.

A kind of portable hand-held immediate action valve opening/closing device is made up of motor 5, one-level retarder 3, two stage reduction gear 1, output pivoted arm 2 and arm bar 7, and motor is a direct current generator; Its output shaft drives the one-level retarder; The output shaft of one-level retarder drives two stage reduction gear again, and the output shaft of two stage reduction gear connects pivoted arm, and pivoted arm is made generally in four directions or hexagonal shaped shape; So that with the coaxial setting-in of valve input device, the torsion that the pivoted arm output torque is bigger gets final product opening/shutting valve.Coaxially on the casing of motor install arm bar, so that the manpower moment of torsion to be provided through mounting plate 6.

For the ease of this device of manual operation, on the one-level retarder, be fixed with a hand-held ring 4.

In addition, a power supply loader 8 is installed also on arm bar, thinks that motor provides electric power.

The use principle of the utility model is:

When using this device, loader is connected the power supply follower with cable, with the pivoted arm connection valve input device of opening/closing device, operation control box can realize the fast opening and closing of valve.

Artificial if desired opening/shutting valve connects the input device of valve with pivoted arm, and the oscillatory forces armed lever can artificial opening/shutting valve.
