Abstract
The utility model provides a self-operated differential pressure regulator controlling a differential pressure(flow). A regulator body is composed of a regulating linkage body connected with the top of a regulator seat. A pressure-sensing film is connected between the regulator seat and the regulating linkage body. An inner chamber of the regulator body is divided into an upper film chamber and a lower film chamber by the pressure-sensing film, and lengthwise connected with a core bar. The bottom of the core bar is connected with a linking core and bar body of the regulator seat, and connected with a spring positioned on the bar body on the upper film chamber. In particular, a regulator controlling the differential pressure communicated with the upper and lower film chamber is disposed at an outside body of the regulator body. The regulator inside is provided with an adjustable orifice. Correspondingly, The top cap of the regulator seat is inside provided with a fixing throttling hole. The utility model has a novel structure and a large adjusting range; can regulate and balance the pipeline network; especially, is suitable of the requirements of adjusting the pipeline network and is a new pipeline regulator controlling the differential pressure.
Description
Technical field
The utility model belongs to a kind of regulating device of mechanical engineering technical field, and concrete is a kind of pipe network control differential pressure regulator.
Background technology
In known technology, existing pipe network control differential pressure regulator mainly is to adopt the Differential Pressure Controller of being made up of valve body load valve gap, spool, diaphragm, spring, seals and other component.It is to adapt to central heating (cold) household metering, supports the variable valve of user from the operation of main variable flow amount.But in actual applications, generally the designer is difficult to accurately calculate indoor resistance, and indoor actual condition drag losses may have very large deviation with the design resistance loss, this has just caused flow error, make that pipe network can not balance movement, therefore, adjustable just the becoming of Differential Pressure Controller control pressure reduction needs problem to be solved.For water-feeding type, the common solution of return type is to utilize to change spring precompressed amount adjusting control pressure reduction.But it is limit by structure, and its range of adjustment is little, can not adapt to the demand that pipe network operation is regulated, and brings inconvenience to use.
Summary of the invention
In order to solve the technical deficiency that existing control differential pressure regulator exists, the utility model provides a kind of novel structure, and range of adjustment is big, can adapt to the needs that pipe network operation is regulated, and realizes the pipe network adjustment, new-type control differential pressure regulator easy to use.
The technical scheme in the invention for solving the technical problem is: adopt by regulator pedestal top to connect the conjuncted regulator body of forming of adjusting, the regulator pedestal with regulate folder company pressure-sensitive film between conjuncted linking to each other, the regulator body inner chamber is divided into the film upper chambers by the pressure-sensitive film, the film lower chamber, and core bar in vertical load in the regulator body inner chamber, the core bar bottom is connected on the connection core of pedestal, the body of rod is worn and is connected the pressure-sensitive film and interlock spring being positioned on the epistege body of rod, particularly be equiped with on the outer lateral body of regulator body on the connection pressure-sensitive film, the control pressure reduction adjuster of lower chamber, be shaped on adjustable orifice in the adjuster, correspondingly and in the top cover cap of regulating pedestal be shaped on fixed orifice, institute's self-operated type pressure reduction that consists of (flow) control differential pressure regulator.It is being continued to use on the basis of spring precompression technology for minimum control pressure reduction, utilizes the mixed pressure technology that pressure-sensitive film pressure reduction ratio is up and down changed, and realizes the adjusting significantly of control pressure reduction, and inner control pressure reduction is adjustable in a big way thereby reach.
Because technique scheme is adopted in the utility model design, it has novel structure, design innovation, characteristics such as range of adjustment is big, can realize the pipe network adjustment, and is easy to use, especially being adapted to the needs that pipe network operation is regulated, is a kind of novel self-operated type pressure reduction (flow) control differential pressure regulator.
