Description
Technical field
The utility model relates to a kind of self-contained pressure regulator, in particular, is the smart small-sized reduction valve of self-powering type internal feedback that a kind of compact structure is exquisite and return difference is little.
Background technique
In recent years, the develop rapidly of domestic valve industry, the product structure type of each valve producer emerges in an endless stream.And self-contained pressure regulator, need not external energy (power supply and source of the gas), utilize and transferred the medium self-energy, introduce the actuating mechanism controls valve element position as power source, change circulation area, change the pressure reduction at two ends, thereby make downstream pressure be stabilized in setting value, therefore have and be active in one's movements, good airproof performance, characteristics such as pressure surge is little, and return difference is little are widely used in the various industry equipments the automatic control occasion to gas, liquid decompression voltage stabilizing.But domestic existing self-contained pressure regulator is not broken away from valve heaviness, structure is bigger than normal and return difference is bigger shortcoming all the time, and its main cause has: 1. the design of filler; 2. the structure of spring external; 3. the structure of actuator's external; 4. adopted outside pilot.These shortcomings are installed and are debugged for the user at the scene and brought a lot of troubles when using.
The model utility content
The purpose of this utility model provides the smart small-sized reduction valve of self-powering type internal feedback that a kind of compact structure is exquisite and return difference is little, break the conventional structure pattern of domestic existing self-contained pressure regulator, solved the above-mentioned common fault of domestic existing self-contained pressure regulator.
To achieve these goals, the technical solution of the utility model is as follows:
The smart small-sized reduction valve of a kind of self-powering type internal feedback, comprise valve body, stifle, valve hole part, seal spool preloading spring, convolution diaphragm, valve gap, pressure setting Regulation spring, adjustable lever, described valve hole part, seal spool preloading spring, convolution diaphragm, pressure are set Regulation spring and all are included in described valve body and the valve gap, MEDIA FLOW directly enters the actuator of described convolution diaphragm through described valve body behind the valve, forms internal feedback structure behind the valve.
As further improvement of the utility model, between described valve hole part and the valve body plane soft seal.
As further improvement of the utility model, constitute piston self balancing structure between described valve hole part and the stifle.
As further improvement of the utility model, described convolution diaphragm is built-in actuator.
As further improvement of the utility model, described pressure is set Regulation spring and the seal spool preloading spring is a split-type structural.
As further improvement of the utility model, described adjustable lever is set in valve top part and carries out the pressure adjusting.
With respect to prior art, the technical solution of the utility model advantage is:
1. no filler in the valve, pressure sets Regulation spring and convolution diaphragm actuator adopts built-in, internal feedback behind the employing valve, pressure is set the split-type design of Regulation spring and seal spool preloading spring, and these factors cause whole valve arrangement essence compact to design little, and has removed annex such as outside PRESSURE PIPE, therefore material and manufacture cost had both been saved, reduced the difficulty of processing and assembling again, shortened the manufacture cycle, and whole thus valve arrangement becomes exquisite attractive in appearance.
2. valve adopts the design that the top is regulated, and is simpler more and quick than the adjusting of former self-contained pressure regulator.
3. valve adopts no filler design, the return difference when having reduced valve switch, and valve event is sensitive more.
4. adopted the plane soft seal between valve hole part and the valve body, good airproof performance, and increased the suitable pressure range of soft seal.
5. valve hole part has adopted the design of piston self balancing, has eliminated the unbalanced force that pressure medium produces, and makes the adjusting function of putting in order valve not be subjected to the influence of pressure medium fluctuation substantially.
6. the built-in actuator of valve adopts convolution diaphragm, and the sensitivity of valve is good, the degree of regulation height.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, the smart small-sized reduction valve of self-powering type internal feedback of the present utility model comprises valve body 4, stifle 1, valve hole part 3, seal spool preloading spring 2, convolution diaphragm 5, valve gap 6, pressure setting Regulation spring 7, adjustable lever 8; Valve hole part 3, seal spool preloading spring 2, convolution diaphragm 5, pressure are set Regulation spring 7 and all are included in valve body 4 and the valve gap 6, and MEDIA FLOW directly enters the actuator of convolution diaphragm 5 through valve body 4 behind the valve, form internal feedback structure behind the valve.
When flowing into medium before the valve, make pressure set Regulation spring 7 by adjustable lever 8 and produce certain decrement, medium acts on the power on the convolution diaphragm 5 behind the equilibrium valve, makes downstream pressure be stabilized in the setting pressure value.When the downstream pressure rising, the power that acts on the convolution diaphragm 5 also increases, and impels pressure to set Regulation spring 7 compressions, and under the effect of seal spool preloading spring 2, valve hole part 3 moves upward, valve closing.Otherwise, when downstream pressure reduces, valve opening.
As shown in Figure 2, valve hole part 3 is designed to the piston self balancing, eliminates unbalanced force, makes the adjusting function of valve stable, is not subjected to the upstream pressure influence of fluctuations.Spool 31 adopts the plane soft seal, with the change that the conical surface seal mode of conventional direct-operated regulator produces matter, good seal performance, and has increased the suitable pressure range of soft seal.
As shown in Figure 3, punch on the runner behind the valve in valve body 4, medium can arrive convolution diaphragm 5 by aperture after making valve, play internal feedback effect behind the valve, thereby removed annexes such as outside PRESSURE PIPE, not only saved cost, make processing convenient, manufacture cycle is also shorter relatively, and the external dimension of having dwindled valve, and whole valve is more exquisite attractive in appearance.
As shown in Figure 4, convolution diaphragm 5 modern designs, other tool idea not only plays actuator, has realized the built-in of actuator, the valve external dimension have been reduced greatly, better meet customer requirement, and also play seal action, realize the no filler design of whole valve, reduce return difference, adjusting function is better.
As shown in Figure 5, adjustable lever 8 designs can conveniently be adjusted pressure set points at the top of valve.
At last, it is also noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model can also have many distortion, and all distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
