Description
Technical field
The utility model relates to a kind of two ore control fluid valve.
Background technique
Fluid valve is by changing cross section or length to control the valve of fluid flow.At present conventional fluid valve its promote mainly through valve rod the control that valve gap carries out flow.During valve body, valve rod can be subject to the impulse force of liquid, and if liquid once withdrawing fluid can be larger to the impulse force of valve rod, easily cause the position of valve rod to offset thus affect the accuracy of fluid flow control.
Model utility content
The purpose of this utility model is to provide a kind of two ore control fluid valve, its structure is simple, easy for installation, hydraulic pressure can not only be prevented the impulse force of valve rod, and can effectively prevent liquid backflow from affecting the position of valve rod, add the working life of valve body while improving valve body flow control accuracy.
In order to achieve the above object, the technical solution of the utility model is:
A kind of two ore control fluid valve, comprise valve body, described valve body comprises water intake, water outlet, and described valve body is provided with valve gap, is provided with valve rod guide rail in described valve gap, and described valve rod guide rail is provided with valve rod, and described valve rod lower end is provided with valve disc; Described valve rod is connected with push rod, is provided with trapezoidal baffle plate in the valve body of described water outlet end, and described trapezoidal baffle plate is connected with push rod; Described valve rod is provided with handwheel.
Be provided with spring between described valve rod and valve disc, described valve rod is connected with valve disc by locating stud.
Described valve disc bottom is separately installed with the first sealing plug, the second sealing plug, and the valve disc between described first sealing plug and the second sealing plug is provided with seal ring.
Be separately installed with between described valve rod and valve gap evagination seal ring, with evagination seal ring with the use of indent seal ring.
Described trapezoidal baffle plate is provided with waterproof membrane.
Described valve body is connected with valve gap by bolt.
The beneficial effects of the utility model are: a kind of two ore control fluid valve, its structure is simple, easy for installation, hydraulic pressure can not only be prevented the impulse force of valve rod, and can effectively prevent liquid backflow from affecting the position of valve rod, add the working life of valve body while improving valve body flow control accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For the ease of understanding the utility model, below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
A two ore control fluid valve as shown in Figure 1, comprises valve body 1, and described valve body 1 comprises water intake 11, water outlet 12, and described valve body 1 is connected with valve gap 2 by bolt 16.In described valve gap 2, valve rod guide rail 3 is installed, described valve rod guide rail 3 is provided with valve rod 4.Described valve rod 4 lower end is provided with valve disc 5.Be provided with spring 8 between described valve rod 4 and valve disc 5, described valve rod 4 is connected with valve disc 5 by locating stud 9.Described valve rod 4 is provided with handwheel 17.
Described valve rod 4 is connected with push rod 6, be provided with trapezoidal baffle plate 7, and described trapezoidal baffle plate 7 is connected in the valve body 1 of described water outlet 12 end with push rod 6.Described trapezoidal baffle plate 7 is provided with waterproof membrane 15.Because valve rod 4 to be connected after therefore valve rod 4 promotes valve disc 5 fluid stopping with push rod 6, push rod 6 promotes trapezoidal baffle plate 7 and dams and prevent liquid backflow.Hydraulic pressure can not only be prevented the impulse force of valve rod, and can effectively prevent liquid backflow from affecting the position of valve rod, while improving valve body flow control accuracy, add the working life of valve body.
Described valve disc 5 bottom is separately installed with the first sealing plug 18, second sealing plug 19, and the valve disc 5 between described first sealing plug 18 and the second sealing plug 19 is provided with seal ring 13.First sealing plug 18, second sealing plug 19 and seal ring 13 with the use of the sealing that improve valve body.Be separately installed with between described valve rod 4 and valve gap 2 evagination seal ring 14, with evagination seal ring 14 with the use of indent seal ring 20.Evagination seal ring 14 and indent seal ring 20 with the use of the sealing that improve between valve rod 4 and valve gap 2.
A kind of two ore control fluid valve of the present embodiment, its structure is simple, easy for installation, and hydraulic pressure can not only be prevented the impulse force of valve rod, and can effectively prevent liquid backflow from affecting the position of valve rod, add the working life of valve body while improving valve body flow control accuracy.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
