Abstract
A kind of nuclear power self-powering type back pressure valve, belongs to valve technology field.It comprises interconnective valve body and valve gap, valve hole part, guide plate and actuator are set in the cavity forming between described valve body and valve gap, described valve hole part lower end coordinates with the valve seat being arranged in valve body, described valve hole part upper end is fixed with actuator through after guide plate, described guide plate is provided with medium holes, and described medium holes communicates with the medium channel that enters of valve body.The utility model has the advantage of: the design that valve adopts top to regulate, more simpler and quick than the adjusting of former self-contained pressure regulator; In valve, without filler design, make valve event sensitiveer, degree of regulation is higher; Valve regulated spring and piston actuator adopt built-in, adopt before valve internal feedback and without filler, whole valve arrangement essence compact to design is little, saved cost, made to process convenient, the manufacture cycle is relatively short, and the external dimension of having dwindled valve, whole valve is exquisiter attractive in appearance.
Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of nuclear power self-powering type back pressure valve.
Background technique
In recent years, domestic valve industry develop rapidly, the product structure type of each valve producer emerges in an endless stream.And self-powering type back pressure regulating valve, without external energy (power supply and source of the gas), utilizes and is adjusted medium self-energy as power source, introduce actuating mechanism controls valve element position, change circulation area, thereby control upstream pressure and flow.But domestic existing self-powering type back pressure valve structure is taller and bigger, valve is heavy, degree of regulation is not high, particularly in the less installing space in nuclear power field, cannot install.
Model utility content
The problem existing for prior art, the object of the invention is to design provides the technological scheme of a kind of nuclear power self-powering type back pressure valve.
Described a kind of nuclear power self-powering type back pressure valve, it is characterized in that comprising interconnective valve body and valve gap, valve hole part, guide plate and actuator are set in the cavity forming between described valve body and valve gap, described valve hole part lower end coordinates with the valve seat being arranged in valve body, described valve hole part upper end is fixed with actuator through after guide plate, described guide plate is provided with medium holes, and described medium holes communicates with the medium channel that enters of valve body.
Described a kind of nuclear power self-powering type back pressure valve, is characterized in that described actuator comprises piston, Regulation spring and adjustable lever, and described Regulation spring is arranged between piston and adjustable lever.
Described a kind of nuclear power self-powering type back pressure valve, is characterized in that described adjustable lever is arranged on valve gap top, and valve gap is stretched out in described adjustable lever upper end, and described adjustable lever lower end coordinates with Regulation spring.
Described a kind of nuclear power self-powering type back pressure valve, is characterized in that described piston outside coordinates with valve bonnet seal.
Compared with prior art, the utility model has the advantage of:
1, valve adopts the design that top regulates, more simpler and quick than the adjusting of former self-contained pressure regulator;
2, in valve, design without filler, make valve event sensitiveer, degree of regulation is higher;
3, valve regulated spring and piston actuator adopt built-in, adopt before valve internal feedback and without filler, these factors make whole valve arrangement essence compact to design little, and remove the annexes such as outside PRESSURE PIPE, not only saved cost, made to process convenient, the manufacture cycle is also relatively short, and the external dimension of having dwindled valve, whole valve is exquisiter attractive in appearance.
Brief description of the drawings
Fig. 1 is model utility general assembly structural drawing.
In figure: 1-valve body; 101-enters medium channel; 102-goes out medium channel; 2-valve hole part; 3-guide plate; 301-medium holes; 4-valve gap; 5-piston; 6-Regulation spring; 7-adjustable lever.
Embodiment
Further illustrate the utility model below in conjunction with Figure of description.
As shown in Figure 1, a kind of nuclear power comprises valve body 1, valve gap 4 with self-powering type back pressure valve and is arranged on valve body 1 and valve gap 4 forms valve hole part 2, guide plate 3 and the actuator in cavity.Valve body 1 is provided with into medium channel 101 and goes out medium channel 102.Actuator comprises piston 5, Regulation spring 6 and adjustable lever 7, and wherein Regulation spring 6 is arranged between piston 5 and adjustable lever 7.Adjustable lever 7 is arranged on valve gap 4 tops, and valve gap 4 is stretched out in adjustable lever 7 upper ends, and lower end coordinates with Regulation spring 6.Piston 5 outsides and valve gap 4 are sealed and matched.Valve hole part 2 lower ends coordinate with the valve seat 8 being arranged in valve body 1, and the piston 5 after guide plate 3 is passed in upper end and in actuator is fixing.Guide plate 3 is provided with medium holes 301, and medium holes 301 communicates with the medium channel 101 that enters of valve body 1.By entering, medium channel 101 is rear directly acts on piston 5 by the medium holes 301 on guide plate 3 to the front medium of valve, forms the front internal feedback structure of valve.
In the time flowing into medium before valve, make Regulation spring 6 produce certain decrement by adjustable lever 7, before equilibrium valve, medium acts on the power on piston 5, makes upstream pressure be stabilized in setting pressure value.When upstream pressure raises, the power that acts on piston 5 also increases, and impels Regulation spring 6 to compress, and at this moment drives valve hole part 2 to move upward, valve opening.Otherwise, in the time that upstream pressure reduces, valve closing.
In the utility model, adjustable lever 7 is arranged on valve top part, can conveniently adjust pressure set points.Piston 5 not only plays actuator, has realized the built-in of actuator, has reduced valve boundary dimension, better meets customer requirement, but also plays seal action, thereby has eliminated filler, makes valve regulated precision higher.Medium holes 301 is set on guide plate 3, before making valve, medium can arrive piston 5 by medium holes 301, play the front internal feedback effect of valve, thereby remove the annexes such as outside PRESSURE PIPE, not only saved cost, made to process convenient, the manufacture cycle is also relatively short, and the external dimension of having dwindled valve, whole valve is exquisiter attractive in appearance.
Shown in the above and figure is only preferred implementation of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
