Description
Technical field
The utility model relates to a kind of flow control valve, especially a kind of adjusting locked type flow control valve.
Background technique
In the prior art, flow control valve is used for the flow that central air-conditioning system is regulated each road waterline of configuration, by adjusting flow control valve is set, and makes the flow of each road pipeline meet the service condition of central air-conditioning system efficient energy-saving.Flow control valve in the market exists with following problem: the Flow-rate adjustment inconvenience, Flow-rate adjustment is inaccurate, it is not directly perceived to regulate the flow indicating value, inconvenient operation, the modulated flow of reserving when trial run is not because flow control valve has reliable locking framework, after operation a period of time, the flow of flow control valve can change, and makes the flow of each road waterline not reach designing requirement, has influenced the operation of central air-conditioning system efficient energy-saving.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned flow control valve, a kind of adjusting locked type flow control valve to be provided.
The utility model is realized with the following method.
This adjusting locked type flow control valve has valve body, and two ends of valve body has water intake and water outlet respectively, and flow regulating tube and flap are housed in the valve body, and flow regulating tube is positioned at the top of flap.Diaphragm, diaphragm pressing plate and bolt are housed below the flap, bolt links together flap, diaphragm and diaphragm pressing plate, dam on forming between flap and valve body mouthful and under the mouth that dams, spring is contained in the inside of bottom flange, the upper end of spring heads on the diaphragm pressing plate, the lower end heads on bottom flange; Regulating valve stem is housed above the flow regulating tube, the flow label is housed above the bonnet, regulates locking plate and lock screw, valve rod passes bonnet, the lower end and the flow regulating tube of valve rod connect together, valve rod top connects together with regulating locking plate, and the O RunddichtringO is housed between valve rod and the valve gap, and regulating locking plate has locating slot and scale index line, lock screw is positioned at locating slot, and the slewing area of regulating valve stem is the sector movable scope of lock screw in locating slot.
Flap, diaphragm, diaphragm pressing plate, bolt and spring are formed the automatic balancing valve group of two mouths that dam, when fluctuation takes place in the flow of water intake or water outlet, can feed back to the also automatic mouth that dams is up and down made of diaphragm and spring immediately and hold adjustment big or that turn down, thereby make flow keep constant.
Flow regulating tube, regulating valve stem, flow label, adjusting locking plate, lock screw are formed a manual Flow-rate adjustment locked type valve group, when system debug, as long as unclamp lock screw, rotate regulating valve stem and drive flow regulating tube simultaneously and the also rotation together of adjusting locking plate, make the scale index line of regulating on the locking plate point to desired flow position on the flow label, screw the position of lock screw then with secured adjusted valve rod and flow regulating tube.
It is convenient to the utlity model has field adjustable, regulates advantages such as flow is accurate, directly perceived.Make the flow of each road water transport pipeline reach designing requirement, central air-conditioning system is in the running state of efficient energy-saving.
