Embodiment 1

[0031] Such as figure 1 As shown, a valve handwheel system using a ratchet structure in the present invention includes a wheel 1 and a wheel handle 2, the wheel 1 includes an inner wheel 8 and an outer wheel 9, and the inner ring of the outer wheel 9 is provided with Ratchet 10, the outer ring of the inner wheel 8 that is connected with the outer wheel 9 is provided with a ratchet block 11, and the wheel 1 is provided with a ratchet structure, which can adapt to a narrow space, and the wheel handle 2 cannot rotate once. easy to use. 3 grooves 7 are arranged in the outer circular array of the outer wheel disc 9, a wheel disc handle 2 is arranged in the groove, and a square hole is arranged in the middle part of the inner wheel disc 8, and a valve stem ferrule 3 is installed in the square hole; The roulette handle 2 is provided with a strip groove 4, and a folding handle 5 is arranged in the strip groove 4, and the folding handle 5 is hinged in the strip groove 4. The section ...

Embodiment 2

[0034] Such as Figure 1-2 As shown, the present invention uses a valve handwheel system with a ratchet structure. On the basis of Embodiment 1, a lock cylinder device 12 is provided on the inner wheel disc 8, and a drawing wire 13 is connected to the lock cylinder device 12. The drawing wire 13 Connect with pawl block 11. A lock cylinder device 12 is arranged on the wheel disc 1, and the valve can be prevented from being accidentally opened by using the hand wheel by locking the pawl block 11. The lock core device can adopt the existing lock core structure to realize its function as the criterion.

Embodiment 3

[0036] Such as Figure 1-3 As shown, the present invention is a valve handwheel system using a ratchet structure. On the basis of Embodiment 1, the front end of the folding handle 5 is provided with a pick-up groove 6 . It is convenient to pull open the folding handle 5 .

Abstract

The invention discloses a valve handle system using a ratchet structure, which comprises a wheel disc and a wheel disc handle, wherein the wheel disc comprises an inner wheel disc and an outer wheel disc; ratchets are arranged on the inner circle of the outer wheel disc; pallet blocks are arranged on the outer circle of the inner wheel disc which is connected with the outer wheel disc in a matching way; three grooves are formed in the outer side of the outer wheel disc in an annular array; wheel disc handles are arranged in the grooves; a square hole is formed in the middle of the inner wheel disc; a valve stem clamping sleeve is mounted in the square hole; strip-shaped grooves are formed in the wheel disc handles; folding handles are arranged in the strip-shaped grooves; and the folding handles are hinged to the strip-shaped grooves. The ratchet structure is arranged on the wheel disc, so that the valve handle system can be adaptive to a narrow space and can be used under the condition that the wheel disc handles cannot rotate for a circle. A lock core device is arranged on the wheel disc, so that the condition that a valve is opened by using a hand wheel by accident is prevented by locking the pallet blocks.

Description

technical field [0001] The invention relates to the field of a valve handwheel device, in particular to a valve handwheel system utilizing a ratchet structure. Background technique [0002] Valves are the control components in the fluid delivery system. The valves used in the fluid control system range from the simplest globe valve to various valves used in extremely complex automatic control systems. There are quite a variety of valves and specifications. Valves can be used to control air, The flow of various types of fluids such as water, steam, various corrosive media, mud, oil, liquid metal and radioactive media; valves that are manually opened and closed are generally equipped with handwheels, which are circular in structure , the principle is to use the radius of the handwheel as the force arm to enhance the rotational torque. Therefore, under the same torque, the larger the radius of the handwheel, the greater the torque. However, the radius of the existing handwheel ...
