Abstract
A kind of modulating valve, installs valve rod in valve body, and stem lower portion installs flap, and valve rod is positioned at flap top and installs Gland, valve body top is provided with valve gap, and valve gap is set on valve rod, flap bottom installing sleeve.Modulating valve of the present utility model, Gland is installed on flap top, and valve gap adopts new structure, thus make the pressure dissipation of highly pressurised liquid on the whole end face of valve gap, the pressure avoiding highly pressurised liquid concentrates the problem causing modulating valve to damage, and flap, achieve sealing between valve gap and valve body completely, prevent water leakage phenomenon.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of pressure regulator valve.
Background technique
Pressure regulator valve is also known as self-balancing valve, flow control valve, flow dontroller, dynamic balance valve, flow equilibrium
Valve is a kind of intuitively easy Flow-rate adjustment control gear.In pipe network, applying pressure modulating valve can directly set according to design
Flow, valve can under water effect, the residual pressure head of automatic elimination pipeline and the flow deviation caused by pressure surge, no matter how system pressure changes all keeps setting flow constant, these functions of this valve make pipe network Flow-rate adjustment once complete, the work of tune net is become simple assignment of traffic, the effective hydraulic misadjustment solving pipe network.
But existing pressure regulator valve, can not seal between the miscellaneous part such as valve body and flap completely, produce phenomenons such as leaking, pressure regulator valve also produces quality problems because not playing pressure regulating action.
Model utility content
In order to overcome the problems referred to above that conventional pressure modulating valve exists, the utility model provides a kind of pressure regulator valve of good airproof performance.
The technological scheme that the utility model is adopted for achieving the above object is: a kind of modulating valve, install valve rod 2 in valve body 6, flap 4 is installed in valve rod 2 bottom, valve rod 2 is positioned at flap 4 top and installs Gland 3, valve body 6 top is provided with valve gap 1, and valve gap 1 is set on valve rod 2.
Described flap 4 bottom installing sleeve 5.
Modulating valve of the present utility model, Gland is installed on flap top, and valve gap adopts new structure, thus make the pressure dissipation of highly pressurised liquid on the whole end face of valve gap, the pressure avoiding highly pressurised liquid concentrates the problem causing modulating valve to damage, and flap, achieve sealing between valve gap and valve body completely, prevent water leakage phenomenon.
Accompanying drawing explanation
Fig. 1 is the utility model regulating valve structure figure.
Embodiment
Regulating valve structure of the present utility model as shown in Figure 1, installs valve rod 2 in valve body 6, and flap 4 is installed in valve rod 2 bottom, valve rod 2 is positioned at flap 4 top and Gland 3 is installed, valve body 6 top is provided with valve gap 1, and valve gap 1 is set on valve rod 2, flap 4 bottom installing sleeve 5.Modulating valve of the present utility model, Gland is installed on flap top, and valve gap adopts new structure, thus make the pressure dissipation of highly pressurised liquid on the whole end face of valve gap, the pressure avoiding highly pressurised liquid concentrates the problem causing modulating valve to damage, and flap, achieve sealing between valve gap and valve body completely, prevent water leakage phenomenon.
The utility model is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various change or equivalence replacement to these characteristic sum embodiment.In addition, under the teachings of the present invention, can modify to adapt to concrete situation and material to these characteristic sum embodiment and can not the spirit and scope of the present invention be departed from.Therefore, the present invention is not by the restriction of specific embodiment disclosed herein, and the embodiment in the right of all the application of falling into belongs to protection scope of the present invention.
