Problems solved by technology

[0004] Existing throttle valves can generally only be used in occasions where the load changes little or the speed stability is not high, because common throttle valves can only control the opening, closing, or half-opening and half-closing of a single valve. To achieve the change of the flow area, and, in the process of valve adjustment, it is easy to cause circumvention, vortex, etc., which seriously affects the stability and continuity of the fluid passing through

Embodiment 1

[0025] like figure 1 As shown, the present invention comprises 7 passages connected in parallel to the upstream straight pipe section 5, and its flow area is respectively 1%, 2%, 3%, 7%, 14%, 28%, 55%, and each passage includes successive connections The flow regulator 1, the flow nozzle 2 and the quick switching valve 3, and each quick switching valve 3 communicates with the downstream straight pipe section 6 through the buffer 4, and the quick switching valve 3 includes two states of fully open and fully closed.

[0026] A flow regulator 1 is used to reduce the length of the upstream straight pipe section 5 and make the fluid flow stably;

[0027] Flow nozzle 2, used to generate pressure difference and measure fluid flow;

[0028] Quick switching valve 3, which includes two states of fully open and fully closed, and these two states can be switched in a very short time;

[0029] The buffer 4 is capable of buffering pressure fluctuations caused by a 1% change in flow amplit...

Abstract

The invention discloses a throttle valve system and a working method thereof. The throttle valve system comprises a plurality of channels which are in parallel connection to an upstream straight pipe section; every channel comprises a flow regulator, a flow nozzle and a rapid switching valve which are sequentially connected; every rapid switching valve of every channel is communicated with a downstream straight pipe section through a buffer; and every rapid switching valve has a full open state and a full closed state. The throttle valve system and the working method thereof have the advantages of conforming to the basic theory of engineering thermodynamics, being capable of continuously changing the flow area to adjust the fluid flow, effectively reducing throttling losses and meeting the requirements of energy conservation and emissions reduction to the greatest extent.

Description

technical field [0001] The invention relates to a throttle valve system, in particular to a throttle valve system and a working method thereof. Background technique [0002] The engineering application of the throttling process can not only use its cold effect for refrigeration, but also can be used to adjust the power of the engine, measure the flow of fluid, etc. Because adiabatic throttling is an irreversible adiabatic process, the entropy of the working fluid must increase, so the working capacity of the working fluid will decrease after throttling. [0003] It is often believed that quality is the degree to which a product meets user requirements. The more a product can meet user requirements, the better its quality will be. Therefore, the current throttle valve is characterized by simple structure and few consumables, and does not fully consider the safety and economic problems caused by throttling (especially when it deviates from the design). This design idea has c...
