Dynamic equilibrium adjusting valve

Abstract

The invention discloses a dynamic equilibrium adjusting valve. The dynamic equilibrium adjusting valve comprises a valve body and a valve element mounted in a valve cavity of the valve body. The valve cavity comprises a water inlet cavity and a water outlet cavity which are sealed and partitioned. The valve element comprises an outer barrel fixedly connected with the valve body, an inner barrel slidably arranged in the outer barrel, and a valve element bottom cover fixed to the bottom of the outer barrel. A pressure sensing plate is arranged at the bottom of the inner barrel. The outer barrel is provided with a water inlet communicating with the water inlet cavity and a water outlet communicating with the water outlet cavity. An inner cavity of the outer barrel serves as a water channel communicating with the water inlet and the water outlet. A flow equilibrium port is formed in the side wall of the inner barrel and can adjust the flowing area of the water outlet along with sliding of the inner barrel relative to the outer barrel. The valve element bottom cover is provided with a central column penetrating through the pressure sensing plate. A fixing base is fixed to the top end of the central column. An elastic part is arranged between the fixing base and the pressure sensing plate. A pressure sensing cavity communicating with the water inlet cavity is formed between the valve element bottom cover and the pressure sensing plate. According to the scheme, the flow adjusting effect of pipe networks can be improved, and stable flow is ensured.

Description

Technical field [0001] The invention relates to the technical field of valve design, in particular to a dynamic balance regulating valve. Background technique [0002] In the variable flow water system of the different pipeline network for fluid transmission and distribution, the system pressure needs to be designed according to the resistance of the loop, usually only based on the resistance of the most unfavorable loop. However, when the working pressure of the most unfavorable loop is guaranteed, the working pressure of other nodes may be much larger than the design value, which will cause the hydraulic imbalance of the system. In addition, excessive or improper selection of the water pump will also cause the operating flow to deviate from the design value, which will lead to the system's hydraulic imbalance. The occurrence of water imbalance in the pipeline network will cause a large amount of waste of energy, increase in operating noise and shorten the service life of equip...

Problems solved by technology

However, when the acting pressure of the most unfavorable loop is guaranteed, the acting pressure of other nodes may be much higher than the design value, which will lead to the hydraulic imbalance of the system

In addition, excessive or improper selection of the water pump will also cause the operating flow to deviate from the design value, which will lead to hydraulic imbalance in the system

And the problem of water conservancy imbalance in the pipe network will cause a lot of waste of energy, increase of operating noise and shorten the service life of equipment

[0003] In order to reduce or eliminate the phenomenon of hydraulic imbalance in the pipe network, it is necessary to continuously debug the system. This method is not only troublesome and time-consuming, but more importantly, this adjustment is lagging behind. disordered phenomenon

In the traditional technology, there is still a solution to this problem by using a dynamic flow balance valve, but this kind of dynamic flow balance valve uses a rubber diaphragm as a pressure balance member. In an environment with poor water quality or high pressure, the rubber diaphragm Susceptible to damage resulting in loss of functionality of the dynamic flow balancing valve

[0004] To sum up, in the traditional technology, the flow regulation effect of the pipe network is not ideal. Therefore, how to improve the flow regulation effect of the pipe network has become a technical problem to be solved urgently by those skilled in the art.
