The invention provides an inlet valve comprising a valve body and a cylindrical valve cavity formed in the valve body. The upper and lower ends of the valve body are respectively formed with an air inlet and an air outlet connected with the valve cavity. The inner wall of the valve body near the outlet end is shaped to have a reaming, the inner wall of the reaming is formed with a thread, and a valve plate in the valve cavity of the valve body is provided. The upper end face of the valve plate is shaped with a protruding table, and a protective cover is fixed with a barrel shaped protective cover on the protruding platform. The protective cover is formed with a number of intake holes. The protective cover is inserted into the intake port of the valve body, the valve plate around the convex platform is fixed with a seal pad on the valve plate, and the seal pad is pressed on the upper bottom surface of the valve body; the protective cover outer cover is provided with a filter. Net. The intake valve provided by the invention provides a protective structure on the air inlet base on the basis of the current hot water discharge intake valve, and modifies the internal structure of the valve body accordingly, from which the discharge valve of the valve has the function of preventing large particles from clogging the intake port.
【技术实现步骤摘要】
一种进气阀
本专利技术涉及热水器设备领域,尤其涉及一种进气阀。
技术介绍
传统的储水式热水器都没有专门的排污排空功能,即使有带有排污排空功能,热水器在排污排空的同时也在进行进气和换气,从而导致排污排空水流断断续续,排污时间较长,现有技术中,通常是在热水器内胆上方固定一种自动进气的进气阀,从而加快排污时间较长,进气通道一般要求较小,从而能持续平衡其内胆内部的负压作用,而其进气阀进气口没有防护结构,容易被大颗粒杂物堵塞,从而丧失功能,而且进入空气较为污浊。
技术实现思路
针对上述技术问题,本专利技术的技术方案是:一种进气阀,包括阀体,阀体内成型圆柱形的阀腔,阀体的上下端分别成型有与阀腔相连通的进气口和出气口,靠近出气口端的阀体内侧壁上成型有扩孔,扩孔的内侧壁成型有螺纹,所述阀体的阀腔内设有阀板,阀板的上端面上成型有凸台,凸台上插套固定有桶状的防护罩,防护罩成型有若干进气小孔,所述的防护罩插接阀体的进气口内,所述的凸台四周的阀板上固定有密封垫,密封垫压靠在阀体的上底面上;所述防护罩外罩设有滤网。进一步改进为,所述阀板的下端面成型有导向柱,导向柱插接在支撑板上,支撑板成型有若干出气孔,所述的支撑板插接在阀体的扩孔内,扩孔内螺接有锁紧套,锁紧套压靠在支撑板的下端面上,支撑板下端面的中心成型有环台,拉簧的一端固定在环台上、另一端固定在固定套上,固定套固定在导向柱的下端,支撑板的环台和固定套的外侧壁上均成型有外螺纹,拉簧的两端分别螺接在环台和固定套上,所述的环台插套在导向柱上。进一步改进为,所述滤网为三层,从外到内依次为初滤层、高效过滤层、活性炭层。进一步改进为,所述高效过 ...
