摘要：本发明公开了一种防水透气阀。它包括阀体以及安装在阀体上的阀盖，阀体内具有用于安装透气膜的腔室，腔室内安装有阀片，阀片与阀体的内壁之间形成气流通道，透气膜安装在阀片上，阀体内还设置有密封圈，密封圈的顶部靠压在阀片的底部，阀片的顶部安置有弹性件，所述弹性件被压在阀片和阀盖之间，腔室内具有压力气体，阀片能够被压力气体推动进而使压力气体进入气流通道并克服弹性件的弹力将压力气体排出。采用上述的结构后，可以通过透气膜正常进行排气，当单独靠防水透气膜排气已不能满足平衡模组内外压时，阀片可以压力气体被推动从而使压力气体进入气流通道并克服弹性件的弹力将压力气体排出，由此实现了超压保护和自动除尘功能。

摘要：本发明公开了一种多阀组联动的临界流实验控制系统及方法包括喷放主管，在喷放主管的上游安装有一个喷放孔板，还包括一个调压支管，调压支管包括一个连接在喷放孔板与第一快速开关阀之间的第一减压阀，第一减压阀串联第一截止阀后连接至第一快速开关阀与第二快速开关阀之间的喷放主管上。本发明首先承受一部分流体的冲击作用力，接着第一快速开关阀动作后随另一部分流体的冲击力，可以使阀门在临界流的实验过程中有效分担流体的冲击力，延长阀门的使用周期。本发明利用调压支管和泄压支管将第一开关阀的压力分担到第一开关阀和第二开关阀两个阀门上，降低了单个阀门的开启压差，更利于第一开关阀的顺利开启，可以有效保护阀门的密封面不被破坏。

摘要： A cooling system includes an inlet port and an outlet port to be coupled to one or more electronic devices, a main loop having a heat exchanger coupled to the inlet port and the outlet port, and a buffer loop coupled to the inlet port and the outlet port. The main loop having a heat exchanger to receive fluid from the inlet port, to extract heat generated by the electronic devices and carried by the fluid, and to return the fluid to the electronic devices via the outlet. In an embodiment, a cooling system includes a buffer loop, configured in parallel with the main loop, with a buffer unit to temporarily buffer at least a portion of the fluid, and a first pressure controllable valve, coupled to the main loop and the buffer loop, to selectively distribute at least a portion of the fluid to at least one of the main loop or the buffer loop based on a fluid pressure of the fluid. In an embodiment, a cooling system includes a bypass loop coupled between the first pressure controllable valve and the outlet port to operate as a direct bypass loop from the inlet port to the outlet port, bypassing the heat exchanger and the buffer unit. Pressure is measured and used for controlling those loops under different working scenarios.

摘要： A pressure regulator is configured for better accuracy and response times at higher inlet pressures. These configurations may integrate two-path control with a pressure-balanced plug. The two-path control may leverage a pair of pilot valves, one with a fixed differential pressure and the other with a variable differential pressure. In one implementation, the device is plumbed so that downstream pressure is sensed at both the actuator and the variable differential pressure pilot valve.

摘要： The invention relates to a valve device (14) for low-viscosity to high-viscosity fluids, especially for fluid plastic material constituents (12) of single or multiple constituent plastic mixtures. The inventive valve device comprises a valve housing (18) with a fluid inflow (20, 30) and a dosing valve (15) which has a dosing nozzle (22) that can be optionally closed or opened by a closing element (23). Said valve device also comprises a pressure control device (40, 44) which influences the fluid in the fluid inflow. In order to maintain a constant fluid pressure in the housing which is not influenced by the position of the closing element, the invention provides that the pressure control device is essentially comprised of a control membrane (40) which can be pneumatically prestressed and which acts upon the closing element (23). The invention enables a particularly easy isobaric control or regulation of the fluid inflow since the fluid pressure on one side of the membrane and acting upon the same is in equilibrium with the air pressure prevailing on the other side, and since the air pressure and thus the control membrane remain practically unchanged due to the compressibility of the gas when the closing element is displaced.
