A squeeze quick opening valve. The front and rear walls of the valve body are respectively provided with a front and rear water holes communicated with the inner cavity of the valve body. The front core, the moving core and the rear core are arranged sequentially from front to back and arranged in the inner cavity of the valve body. The through holes corresponding to the front and rear water holes on the valve body are arranged on the front core, the moving core and the rear core. The bottom end of the inner cavity of the valve body corresponding to the moving spool is provided with a concession groove corresponding to the moving spool, and the spring is arranged between the moving spool and the concession groove. The front water hole on the valve body is connected with the through hole on the front core through the front sealing ring, and the back water hole on the valve body is connected with the through hole on the back core through the back sealing ring. The valve cover is arranged on the upper end of the valve body cavity, the driving shaft is arranged in the shaft hole on the valve cover, and the lower shaft head of the driving shaft is connected with the moving valve core in the valve body. The moving spool is pressed into the relief groove on the valve body by the driving shaft, and the front and rear water holes on the valve body can be closed when the through holes on the moving spool are completely dislocated from the through holes on the front and rear spools.

挤压式快开阀
本技术涉及一种快开阀,尤其是能通过挤压方式快捷开关的挤压式快开阀。
技术介绍
目前,公知的快开阀为旋转开关式结构,由于其结构比较复杂,因此不仅体积较大并且开关也不够方便快捷。
技术实现思路
为了克服现有的旋转式快开阀在开关时不够方便快捷的不足,本技术提供一种挤压式快开阀,该挤压式快开阀不仅能通过挤压的方式进行方便快捷的开启和关闭,并且结构简单体积小巧。本技术解决其技术问题所采用的技术方案是:本技术包括阀体、阀盖、水孔、按钮、驱动轴、限位槽、定位销、前定芯、后定芯、动阀芯、密封圈、让位槽和弹簧。阀体为桶体形结构,阀体的内腔设置为矩形凹槽式结构,在阀体的前后桶壁上分别开设有与阀体内腔连通的前后水孔。前定芯、动阀芯和后定芯从前向后顺序排列并设置在阀体的内腔中,所述的前定芯、动阀芯和后定芯均为矩形柱体结构,在前定芯、动阀芯和后定芯上均开设有与阀体上的前后水孔相对应的通孔。在动阀芯所对应的阀体内腔的底端开设有与动阀芯相对应的让位槽,所述的让位槽为矩形凹槽式结构。弹簧设置在动阀芯与让位槽之间。在前定芯的前端面与阀体内腔的前端面之间设置有前密封圈,阀体上的前水孔与前定芯上的通孔通过前密封圈连通。在后定芯的后端面与阀体内腔的后端面之间设置有后密封圈,阀体上的后水孔与后定芯上的通孔通过后密封圈连通。阀盖设置在阀体内腔的上端口上,在阀盖上开设有垂直贯通阀盖的轴孔,阀盖的下端面与前定芯、动阀芯和后定芯的上端面连接。驱动轴设置在阀盖上的轴孔中,驱动轴的上轴头与位于阀体外部的按钮连接,驱动轴的下轴头与阀体中的动阀芯连接,所述的驱动轴的直径小于或等于动阀芯的厚度。在驱动轴上 ...
