Abstract
The utility model relates to a dynamic flow and pressure-difference balancing valve. The valve comprises a manual part, an automatic part and a diaphragm cavity, wherein the automatic part consists of a valve core, a piston, a spring and a diaphragm; one end of the valve core penetrates the interiors of the piston and the spring in sequence; the diaphragm is arranged at the lower end of the spring; the piston, the spring and the diaphragm are all arranged in the diaphragm cavity; the diaphragm cavity is formed by an upper diaphragm cavity and a lower diaphragm cavity; and a mixed pressure regulating device and an exhaust valve are mounted on the surface of the diaphragm cavity. The valve has the advantages of simple structure, high automation, integration of flow control and pressure difference control, easy operation, high control precision, and wide application, not only reduces the resistance and noise of a valve gate, but also completely solves the problem of unbalanced dynamic flow in a pipe network system, thereby creating favorable conditions for the energy conservation of the system.
Description
Technical field
The utility model belongs to a kind of water system balance device technique field in air-conditioning, heating, the water system, especially a kind of dynamic flow differential pressure balancing valve.
Background technique
At present, people often complain because supply water inhomogeneous in air-conditioning, heating, water system, such as the same storied building room, the floor water supply flow that has is too big, and the floor water supply flow that has is too little, causes the room that has too hot, the room that has is too cold, and bigger noise is arranged.In order to solve the drawback that causes because of water flow is inhomogeneous, people just solve this type of problem by dress with Cheng Guandao, but have but taken big quantity space, increase a large amount of installation fee and material cost.In addition, this structure can't make the flow of water system remain within the constant scope, also can increase to the damage of equipment and the loss of pipeline the energy consumption when increasing equipment operation.In addition, people can also use the dynamic flow metered valve to solve this type of problem, but because the manual control mode of the many employings of existing flow balance valve, the adjusting control accuracy is low, cause the resistance of valve big, and the control of the pressure reduction of valve is unstable, can't quantize the max-flow quantitative limitation, also be easy to generate noise, therefore be difficult to guarantee user's demand.
The model utility content
Outside the deficiency that exists in the above-mentioned technology, the utility model provides control of a kind of afflux amount and pressure reduction to be controlled in the whole body, and the automaticity height can reduce a kind of dynamic flow differential pressure balancing valve of valve resistance and valve noise.
For achieving the above object, the utility model provides a kind of dynamic flow differential pressure balancing valve, comprise manual part, automatic part and film chamber, described manual part is arranged at the upside of described automatic part, described automatic part is made of spool, piston, spring and diaphragm, one end of described spool is arranged in the inside of described piston and described spring successively, and described diaphragm arrangement is in the bottom of described spring.
Described piston and described spring and described diaphragm all are arranged at the inside in described film chamber.
Described film chamber is made of last film chamber and bottom film chamber, and the surface in described film chamber also is provided with mixed pressure controlling device and outlet valve.
Described mixed pressure controlling device is made of low pressure introducing port and high pressure introducing port.
Described outlet valve is arranged at the described outer surface of going up film chamber and described bottom film chamber respectively.
Described low pressure introducing port and described high pressure introducing port are arranged at the described outer surface of going up film chamber and described bottom film chamber respectively.
Described manual part is a lifting type structure in the spiral.
Compared with prior art, the utlity model has following advantage:
The dynamic flow differential pressure balancing valve that the utility model provides, comprise manual part, automatic part and film chamber, wherein, automatically part is made of spool, piston, spring and diaphragm, one end of spool is arranged in the inside of piston and spring successively, and diaphragm arrangement is in the lower end of spring, and piston and spring and diaphragm all are arranged at the inside in film chamber, the film chamber is made of last film chamber and bottom film chamber, and the surface in film chamber also is provided with mixed pressure controlling device and outlet valve.Control of the utility model afflux amount and pressure reduction are controlled in all over the body, simple in structure, the automaticity height, easy to operate, manufacturing is with low cost, the control accuracy height, applied widely, not only reduced valve resistance and valve noise, also thoroughly solved the unbalanced problem of dynamic flow of pipe network system, the energy-conservation supremacy clause that provides of system has been provided.
Description of drawings
Fig. 1 is embodiment's cross-sectional view of the present utility model.
The primary component symbol description is as follows:
1 manual part, 2 film chambeies, 3 spools
4 pistons, 5 springs, 6 diaphragms
8 bottom film chambers, 9 outlet valves in film chamber on 7

Embodiment
For clearer statement the utility model, the utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is embodiment's cross-sectional view of the present utility model, and the utility model provides the dynamic flow differential pressure balancing valve, comprises manual part, automatic part and film chamber.Wherein, manually part 1 is arranged at the upside of automatic part, and manually part 1 is a lifting type structure in the spiral, and part is made of with diaphragm 6 spool 3, piston 4, spring 5 automatically, and film chamber 2 is made of last film chamber 7 and bottom film chamber 8.Piston 4 and spring 5 and diaphragm 6 all are arranged at the inside in film chamber 2, and an end of spool 3 is arranged in the inside of piston 4 and spring 5 successively, and diaphragm 6 is arranged at the lower end of spring 5.Also be provided with mixed pressure controlling device and outlet valve 9 on the surface in film chamber 2.This mixed pressure controlling device is made of low pressure introducing port 10 and high pressure introducing port 11, and is arranged at the outer surface of film chamber 7 and bottom film chamber 8 respectively, and outlet valve 9 also is arranged at the outer surface of film chamber 7 and bottom film chamber 8 respectively.The effect of outlet valve 9 is time that starts valve can be produced unnecessary air to derive, thereby minimizing gas is to the interference of automatic part.
Working principle of the present utility model is: when adopting dynamic flow balance valve, valve body imports influent pressure automatically and goes up in the film chamber, and water outlet pressure is imported in the bottom film chamber, and manually part is regulated the size of constant flow rate, automatically the pressure reduction between constant water inlet of part and the water outlet; When adopting dynamic differential pressure balancing valve, high pressure is connected with last film chamber, the water outlet pressure of valve body imports bottom film chamber, limits its maximum flow by manual part.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
