Background

The balance valve is a valve with special function, and the valve itself has no special features, and only has differences in use function and place. In some industries, since a medium (various flowable materials) has a large pressure difference or flow difference in each part of a pipe or a container, in order to reduce or balance the difference, a valve is arranged between the corresponding pipes or containers to adjust the relative balance of pressures on two sides or achieve the balance of flow by a shunting method, and the valve is called a balance valve.

Patent numbers: CN109798380A discloses a balance valve, which is designed such that when the central member is lifted by an external force, the second friction structure can move upward together with the central member and generate a relative movement with the first friction structure. When the second friction structure moves to be opposite to the first friction structure, the first sealing element can play a sealing role, so that two sides of the first sealing element are not communicated with each other. With the long-term opening and closing of the balance valve, the first sealing element, the first friction structure and the second friction structure are easy to damage, so that the sealing performance is poor, at the moment, only the first sealing element, the first friction structure and the second friction structure need to be replaced, other parts such as the outer sleeve and the central piece do not need to be replaced, and the tool maintenance cost is reduced.

However, the above patents have the following disadvantages: 1. the above design of the balancing valve does not perform well in pressure regulation and therefore needs to be improved. 2. The safety of the handle is low, so that improvement is needed.
