Embodiment Construction

[0009] The structure and effects of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] The present invention is realized as follows: the condensed water recovery pump is composed of a condensed water inlet check valve, a condensed water outlet check valve, a liquid storage tank, a float control mechanism with a gas inlet and an air discharge port, and equipment legs. . The condensed water inlet check valve consists of disc, spring, valve seat, etc. The installation direction ensures that the valve opens when the condensed water enters and closes when the tank enters the air. The structure of the condensate outlet one-way valve is basically the same as that of the water inlet valve, except that the installation direction is opposite. When there is no pressure or low pressure in the tank, the valve closes, and when the inlet pressure in the tank reaches a certain level, the valve opens. Float control mechanism include...

Abstract

The condensated water recovering pump includes non-return inlet valve, non-return draining valve, tubular pump body, and float ball controlled valve opening and closing mechanism. The float ball controlled valve opening and closing mechanism consists of float ball, front and back float ball level sections, valve body, spring, oscillating disc, valve rod and clack. The present invention features the non-return inlet valve and non-return draining valve set on the tubular pump body, the float ball controlled valve opening and closing mechanism, the two-section elbow structure of the float ball controlling level, the upper and the lower baffles set in the elbow, and the air inlet valve clack and air outlet valve clack on the same valve rod. The condensated water recovering pump has compact structure and small volume, is powered by the steam in thermodynamic system, needs no complicated control system, and may be used in closed condensated water recovering system.

Description

1. Technical field [0001] The invention relates to a condensed water recovery pump, in particular to a float-controlled condensed water recovery pump driven by steam or compressed air. 2. Background technology [0002] In production devices, the condensed water produced by heat exchange equipment is a valuable energy resource. At present, the condensed water in many devices is recycled openly or not recycled at all. pollute. In the recovery method, the jet condensate recovery system is mainly used at present. This system has problems such as complex structure configuration, large additional energy consumption, need for instrument control system, and relatively large investment. The document "Closed Condensed Water Recovery Technology" ("Energy Research and Utilization" No. 2, 1999) introduces the closed condensed water recovery device commonly used in China at present. Corrosion needs to be pressurized in front of the centrifugal pump. A jet pump is installed in front of t...
