Abstract

本结构适用于输送冷媒压缩机的控制阀,其主要在于压缩机上方设置具有活塞、拉伸弹簧的控制阀,并配合电磁阀连接温度控制器使控制阀形成冷媒输送是在离合器与压缩机啮合正常运转下,产生高压流量推动活塞切断冷媒流动,再由拉伸弹簧拉回活塞,启动冷媒流动,形成压缩机输送冷媒自动控温,减少了离合器与压缩机在高速运转下突然作啮合或分离动作,延长了其使用寿命。

Description

压缩机的新型控制阀结构
本实用新型设及一种压缩机的新型控制阀结构,适用于输送冷媒压缩机的控制阀。
目前一般冷气空调或冷冻机需藉压缩机输送冷媒,但传统压缩机配合工作图(如图1、2所示)仅作单一流量接通,功能单一,且冷媒输送切换是在马达高速运转状况下,利用切换开关使离合器突然啮合或分离压缩机,作为压缩机切换控制,容易造成离合器与压缩机的磨损及损耗,减少其使用寿命。
为克服上述缺点,本实用新型提供了一种压缩机的新型控制阀结构。
本实用新型的目的是这样实现的,在低压控制阀内设置具有活塞及拉伸弹簧的控制阀,配合温度控制器及电磁阀,在压缩机及离合器正常啮合运转情况下,产生高压流量推动活塞切断冷媒流动,再由拉伸弹簧拉回活塞,启动冷媒流动,形成压缩机输送冷媒自动控温,从而延长压缩机与离合器的使用寿命。
图1为传统结构组合图;
图2为传统的高压阀剖视图;
图3为本实用新型结构组合示意图;
图4为本实用新型高压阀剖视图;
图5为本实用新型低压阀剖视图。
结合附图对本实用新型的结构及实施例说明如下:
参阅图3、图4及图5,主要是压缩机10设置高压控制阀30(如图4所示)及低压控制阀50(如图5所示),该低压控制阀50的接头管56连接一电磁阀40,且电磁阀40连接一温度控制器及连接输送管41,该输送管41另一端连接高压控制阀30(如图4所示),该低压控制阀50内设活塞51,并顺序装入阀杆52及拉伸弹簧53再锁固阀盖54,最后再与把手59螺纹连接,另於低压控制阀50外侧分别连接接头55、56,并於对称端设一入口57可与压缩机10连接,而上端锁固一接头58可与低压输送管70接合(如图3所示),该高压控制阀30於外侧连接接头管33,并与输送管41连接,且高压控制阀30的接头管34连接一高压输送管71。
当压缩机10与离合器贴合连接正常运转,将冷媒由压缩机10高压排出经高压阀30至高压输送管71输送形成冷气作用,再由低压输送管70藉由低压阀40的接头58至出口57再进入压缩机10,形成冷气的冷媒循环,待温度冷至下限时,压缩机10与离合器继续正常运行,不需将其分离状况之下,温度控制器即启动电磁阀40动作,令冷媒由高压控制阀30的接头管33经由电磁阀40进入低压控制阀50的接头管56,由于其压力大于拉伸弹簧53的拉力,而推动活塞51顶住接头58,切断冷媒由低压控制阀50的出口57流经接头58至低压输送管70,换言之,停止冷媒传递运行;待温度回温至上限时,压缩机10与离合器亦继续正常运行,温度控制器即关闭电磁阀40,该冷煤即无法由高压控制阀30进入低压控制阀50的接头管56,拉伸弹簧53即将活塞51拉回,使冷媒亦可与低压控制阀50的接头58及出口57形成通路,即冷媒形成循环作用,如此按所设定温度范围形成自动控温;另,低压控制阀50可按实际的需要将把手59松下再旋紧阀杆52进行调整,切断冷媒由低压控制阀50的出口57流经接头58至低压输送管70,换言之,停止冷媒运作。
本实用新型的主要优点:1,利用具有活塞及弹簧的低压控制阀配合电磁阀及温度控制器形成的自动控制,亦可进行手动控制,来控制温度保持所需温度的范围内。2,本实用新型可使冷媒输送是在离合器与压缩机作啮合正常运转下形成自动控温,减少了离合器与压缩机在高速运转下作啮合或分离动作,从而延长了其使用寿命。3,本控制阀可依实际状况的需要形成控制阀及工作阀双重功效。
综上所述,本实用新型系利用简易元件使冷媒输送是在离合器与压缩机作啮合正常运转下,产生高压流量推动活塞切断冷媒流动,再由拉伸弹簧拉回活塞,启动冷媒流动,形成压缩机输送冷媒自动控温,从而延长该压缩机与离合器的使用寿命。
