Abstract
The utility model relates to a self-operated balancing valve which is composed of a main valve body and a subsidiary valve body. A turbo driven butterfly valve is connected between the main valve body and the subsidiary valve body. The bottom of the main valve body is provided with a bottom cover, the cavity is provided with an automatic valve core and an automatic valve rod, and the top is communicated with a capsule. The inner part of the capsule is provided with a diaphragm, and the top of the diaphragm supports against a spring. The place between the subsidiary valve body and the upper part of the capsule is connected with a water guide tube which is provided with a small water valve. The utility model has the advantages of novel design, compact structure, and complete function, not only can keep constant and reasonable distribution of the fluid flow, but also can play the role of cutting off as a usual valve.
Description
The utility model relates to the valve on a kind of fluid pipe-line, especially a kind ofly can overcome the unbalanced self-balancing valve of fluid flow in water supply, heat supply or the air-conditioning system.
Along with the continuous increase of City Building, caused the difference of the potential height between building and one-storey house, the housing-group, produced fluid flow or the uneven permanent problem of heat supply in water supply, heat supply or the air-conditioning system, influenced industrial production and resident's life.
The purpose of this utility model is the problem at above-mentioned existence, and provide a kind of self-balancing valve, it can overcome the unbalanced problem of fluid flow in water supply, heat supply or the air-conditioning system effectively, can realize the reasonable distribution and the weight feed of flow again and end open close effect, improve disparities between supply and demand, saved the energy.
The purpose of this utility model is achieved in that a kind of self-balancing valve, it is made of main valve body and auxiliary valve body, connecting the moving butterfly valve of snail between main valve body and the auxiliary valve body, bottom is arranged at the main valve body bottom, and automatic spool and automatic valve rod are housed in the chamber, and top is being communicated with bellows, be provided with diaphragm in the bellows, diaphragm top heads on spring, is connected to aqueduct between auxiliary valve body and the bellows top, and little water valve is housed on the aqueduct.This equilibrium valve is to utilize pressure reduction to be power, and the linkage process of moving butterfly valve by diaphragm, automatic valve rod, automatic spool and snail reaches the balance of fluid flow and the purpose of reasonable distribution.
The utility model modern design, compact structure, multiple functional, can keep the constant and reasonable distribution of fluid flow, can play again general valve by effect, have the use promotional value.
As shown in Figure 1, a kind of self-balancing valve, it is made of main valve body (5) and auxiliary valve body (10), it is characterized in that: connecting the moving butterfly valve (9) of snail between main valve body (5) and the auxiliary valve body (10), bottom (6) is arranged at main valve body (5) bottom, automatic spool (4) and automatic valve rod (11) are housed in the chamber, top is being communicated with bellows (2), be provided with diaphragm (3) in the bellows (2), diaphragm (3) top heads on spring (1), be connected with aqueduct (7) between auxiliary valve body (10) and bellows (2) top, little water valve (8) is housed on the aqueduct (7).Its working procedure is, after liquid (water) enters main valve body (5), respectively from last, the bottom of automatic spool (4) enters the moving butterfly valve (9) of snail down, there is fraction water to enter diaphragm (3) bottom of bellows (2) from valve body (5) die cavity top, waterpower jack-up diaphragm (3), again because of being subjected to the anti-top power effect of spring (1), the inlet of control water, when water moves butterfly valve (9) by snail, regulate the moving butterfly valve (9) of snail and open indication, set required flow, flow through some water of butterfly valve (9) back and enter in the bellows (2), head on diaphragm (3) and move down, cause that diaphragm (3) produces pressure reduction by little water valve (8) and aqueduct (7), original state of equilibrium changes, when diaphragm (3) was downward, valve rod (11) moved down automatically thereupon, impels spool (4) to decline, reduce the following fluid passage of spool (4), reduced the throughflow of liquid.Along with the minimizing of flow, the liquid measure that enters bellows (2) top also reduces, and pressure reduction also dwindles, and valve rod (11) and spool (4) rise again automatically, and passage enlarges again, and under so continuous situation of change, it is constant that fluid flow tends to gradually.In actual use, this constant flow is very fast can reach.Simultaneously no matter how upstream pressure changes, the flow behind the valve remains constant, the size of its flow or distribute, by controlling by butterfly valve (9).Thereby the utility model solved the unbalanced problem of fluid flow in water supply, heat supply or the air-conditioning system, realized the reasonable distribution and the weight feed of fluid, improved disparities between supply and demand, saved the energy.
