The invention relates to the technical field of balance valves, in particular to a balance valve for an aerial ladder carrying vehicle. Which comprises a valve body and is characterized in that a first oil way is arranged in the valve body, the first oil way comprises a first oil port, a first branch port, a second branch port and a first load port which are arranged in sequence, a one-way throttle valve is arranged between the second branch port and the first load port and comprises a second one-way valve and a throttle valve body, and the second one-way valve and the throttle valve body are arranged on the valve body. The throttling direction of the one-way throttling valve to the oil is that the oil flows from the first load port to the second branch port. According to the technical scheme, the problem that in the prior art, when an internal one-way valve of a balance valve used for an aerial ladder carrier loses efficacy, a load rapidly falls off easily, and losses are caused is solved.
该发明涉及平衡阀技术领域,尤其涉及云梯搬运车用平衡阀。包括阀体,其特征在于:所述阀体的内部设有第一油路,所述第一油路包括顺次设置的第一油口、第一分支口、第二分支口和第一负载口,所述第二分支口和第一负载口之间设有单向节流阀,所述单向节流阀包括第二单向阀和节流阀,所述单向节流阀对油液的节流方向为,油液从第一负载口流向第二分支口。本技术方案用以解决现有技术中云梯搬运车使用的平衡阀,在其内部单向阀失效时,易导致负载快速坠落造成损失的问题。
