Example Embodiment

[0009] The structure of the embodiment of the present invention will now be described in conjunction with the accompanying drawings: a sequential valve with temperature memory, as shown in the accompanying drawings, consists of a main body 3, a main body seat 13, a pressure regulating rod 1, transmission plates 5c and 5d, and a compression spring 12. Composed of air inlet 14a and air outlet 14b.

[0010] The main body 3 is seated on the main body seat 13 through fasteners, and a cavity 4 is formed between them. A circlip 11 for holes is embedded in the cavity 4 , and a sealing block 10 is seated on the circlip 11 for holes. Then the sealing block 10 divides the cavity 4 into two independent spaces, upper and lower, of the sampling cavity 4a and the discharge cavity 4b. A transmission rod 9 passes through the sealing block 10 and can slide therein, and its two ends are respectively located in different areas of the sampling cavity 4a and the discharge cavity 4b.

Abstract

The invention refers to a temperature memory sequence valve. The existing sequence valve chamber is separated into sampling chamber and discharging chamber which are each independent space. Memory spring which is made of shape memory alloy is equipped in the sampling chamber, and sampling import and sampling export which are equipped in the main body where the memory spring is equipped are each connected to the sampling chamber and the outside. Quantity of heat of the sampling fluid body which comes into sampling chamber by sampling import will make the memory spring occur to change shape-the memory spring will be extended or shorten. It can change the magnitude of the pressure to realize automatically adjust the controlled air's discharge or not. So it can achieve the prospective purpose of decreasing energy consumption of the air supply system, and economize valuable resource.

Description

Technical field [0001] The invention relates to a sequence valve, and more particularly relates to a sequence valve with temperature memory for an air supply system. Background technique [0002] With the continuous development of the communication industry, the communication cable air supply system has played a vital role in the normal operation of the communication system. For this reason, general sequence valves have been widely used in current communication cable air supply systems to obtain as dry air flow as possible, but the general sequence valves in the prior art do not have the function of automatic adjustment, so in order to obtain as dry air flow as possible, it may The entire gas supply system is always in a state of high energy consumption. It will not automatically adjust according to changes in environmental conditions under the premise of meeting the use requirements, so it is not conducive to saving energy and reducing system operating costs. Especially in...
