Pneumatic passenger door pump safety buffer valve
The invention belongs to the technical field of buffer valves, in particular to a pneumatic passenger door pump safety buffer valve. The buffer valve comprises a valve body, wherein an installation hole is formed in the upper left side of the valve body, a throttle valve seat is installed in the installation hole, a throttle valve core is installed in the middle of the throttle valve seat, a locking nut is screwed on the left side of the outer wall of the throttle valve core, a one-way valve is installed on the right side of the throttle valve seat, and comprises a one-way valve spring and a one-way valve core, the right end of the throttle valve seat is fixedly connected with the one-way valve spring, the one-way valve core is fixedly connected to the right end of the one-way valve spring, and a first threaded hole is formed in the left side of the valve body, and is located on the lower side of the throttle valve seat. When compressed air is absent in a cylinder, the air pressure ofa communicating cavity in the buffer valve is zero and the one-way valve is closed; and during ventilation, the compressed air is slowly supplied to the cylinder through a throttle valve in the buffervalve, so that a piston of the cylinder moves slowly to avoid impact.
本发明公开的属于缓冲阀技术领域，具体为气动乘客门泵安全缓冲阀，包括阀体，所述阀体上方左侧开设有安装孔，所述安装孔安装有节流阀阀座，所述节流阀阀座中部安装有节流阀阀芯，所述节流阀阀芯外壁左侧螺接有锁紧螺母，所述节流阀阀座右侧安装有单向阀，所述单向阀包括单向阀弹簧和单向阀阀芯，所述节流阀阀座右端与单向阀弹簧固定连接，所述单向阀阀芯固定连接于单向阀弹簧右端，所述阀体左侧开设有第一螺纹孔，所述第一螺纹孔位于节流阀阀座下侧，当气缸内没有压缩空气的时候，缓冲阀内连通腔的气压为零，单向阀关闭；通气时，压缩空气通过缓冲阀内的节流阀向气缸缓慢供气，使气缸活塞慢速移动，避免产生冲击。
