Abstract
The utility model belongs to the field of fluid control, and particularly relates to a fluid control device for connecting and disconnecting a fluid path. According to the technical scheme of the utility model, a body is internally provided with an inlet and an outlet; the body is internally provided with a valve; the valve is internally provided with a seal assembly; one end of the seal assembly is connected or contacted with a sliding assembly, and the other end of the seal assembly is connected or contacted with a compressing assembly. The fluid control device has the beneficial effects that a seal structure adopts an improved one-way valve, the sealing reliability of a sealing pair between the seal assembly and the body is ensured, and the seal ring is prevented from being cut during the moving process, so that the service life is prolonged; the valve is quick in response speed and can realize quick conduction; and a sealing part is little in range of precision requirement, easy to ensure and simple to process. Moreover, the vulcanized seal ring and the valve on the seal assembly are matched so as to achieve the best sealing effect; more importantly, through a convenient adjustable structure adopted by a pretightening force of a spring, the product can be suitable for different working conditions and is multi-purpose.
Description
Technical field
The utility model belongs to fluid control field, is specifically related to the automatic controller that the convection cell path carries out switching.
Background technique
In liquid control system, relate to the operation that switching frequently need be arranged some path, such operation relies on manpower to finish certainly and can not finish, and must rely on control automatically and regulating system could realize its effect.
The like product of present stage, the structure applications of sliding type is more, is slide bar is set in cavity, there is seal ring to realize its sealing on the slide bar, slide bar straight line motion simultaneously utilizes the difference in radial fit gap between slide bar and the housing, realizes blocking and conducting of pipeline.
Said structure, during slip, seal ring by the seamed edge of the joint of cross hole incised wound, causes product failure or destruction easily, directly influences product usability and working life; And because closed hole is elongated hole structure, stroke is long, requires the matching part size of closed hole long partially, has the dimensional range of required precision big, causes difficulty of processing big.And this sliding structure is when slide bar carries out axial motion, and surface friction drag is relatively large, directly has influence on the control accuracy of product.
In addition, the product of present stage, narrow application range makes that the product type parameter is numerous, cost of production is high.
Summary of the invention
The purpose of this utility model provides a kind of precision height, good reliability, the life-span is long, difficulty of processing is little fluid control device, to remedy the deficiency of prior art.
The technological scheme of the utility model for realizing that purpose adopts:
Fluid control device comprises body, and import and outlet are arranged in the body; It is characterized in that: valve is arranged in the body, black box is arranged in the valve, black box one end connects or the contact sliding assembly, and the other end connects or contact holds down assembly;
The valve sectional shape is taper; Seal ring is arranged on the black box, and seal ring vulcanizes in the annular groove of black box;
Hold down assembly and comprise spring footstock and spring pedestal between spring footstock and the spring pedestal pressure adjusting spring being arranged;
Be provided with adjusting axle and contact with spring pedestal, adjusting axle and connecting sleeve screw-thread fit are come the pretightening force of Regulation spring by the axial displacement of adjusting axle.
Optimize, sliding assembly comprises sealing seat and sensing piston, wherein the pressure of sensing piston perception sensing mouth.
Good effect of the present utility model is: sealing configuration adopts improved check valve, has both guaranteed the sealing pair sealing reliability between black box and the body, and seal ring can not hurt in moving process, has therefore prolonged working life; The valve speed of response is fast, can realize quick conducting; Sealing place has the scope of required precision little, guarantees easily, and processing is got up simple.In addition, the seal ring that vulcanizes on the black box and valve cooperate can reach best sealing effect, the more important thing is: the adjustable structure easily that the pretightening force of spring adopts, and make this product can be applicable to different operating modes, reach the purpose of one-object-many-purposes.

Embodiment
Embodiment 1:
Referring to Fig. 1, this product comprises piston body 1, seal ring 2, sensing piston 3, seal ring 4, sealing seat 5, body 6, black box 7, spring footstock 8, connecting sleeve 9, pressure adjusting spring 10, spring pedestal 11, adjusting axle 12, locking nut 13, seal ring 14, seal ring 15.Wherein sulfuration has seal ring 16 in the annular groove of black box.
The pressure of detected fluid is passed to sensing piston 3 through sensing mouth 100 places of piston body 1, is passed to the left end of black box 7 again by sealing seat 5, and the active force of pressure adjusting spring 10 is passed to the right-hand member of black box 7 by spring footstock 8.The big I of spring force is regulated by the position that screws adjusting axle 12.In limiting pressure range, the fluid sensing power that the spring force that black box 7 right-hand members are subjected to is subjected to greater than left end, this moment, pilot valve was in closed condition, import 101, outlet 102 not conductings.When sensing mouth 100 place's pressure of piston body 1 are elevated to the setting high pressure, pressure is passed to sensing piston 3, be passed to black box 7 by sealing seat 5 again, black box 7 left ends are subjected to the spring force that fluid sensing power is subjected to greater than right-hand member, black box 7 moves to right-hand member, sealing pair between black box 7 and the body 6 is opened, import 101, outlet 102 conductings immediately, and fluid is discharged through exporting 102 by import 101 rapidly.
Embodiment 2:
The pressure of detected fluid is passed to sensing piston 3 through sensing mouth 100 places of piston body 1, is passed to the left end of black box 7 again by sealing seat 5, and the active force of pressure adjusting spring 10 is passed to the right-hand member of black box 7 by spring footstock 8.The big I of spring force is regulated by the position that screws adjusting axle 12.In limiting pressure range, the spring force that black box 7 right-hand members are subjected to is subjected to fluid sensing power less than left end, and this moment, pilot valve was in closed condition, import 101, outlet 102 not conductings.When sensing mouth 100 place's pressure of piston body 1 are reduced to setting low pressure, pressure is passed to sensing piston 3, be passed to black box 7 by sealing seat 5 again, black box 7 left ends are subjected to the spring force that fluid sensing power is subjected to less than right-hand member, black box 7 moves to left end, sealing pair between black box 7 and the body 6 is opened, import 101, outlet 102 conductings immediately, and fluid is discharged through exporting 102 by import 101 rapidly.
