Abstract
The invention discloses a rotationally opening and closing liquid pipeline valve. The rotationally opening and closing liquid pipeline valve comprises a valve sleeve, a valve plate and a valve rod, wherein two open holes for the two ends of the valve rod to penetrate through are formed in the valve sleeve; two fixing bases are installed on the valve plate; a circular hole with the same diameter as that of the valve rod is formed on each of the fixing bases; the valve rod penetrates through the circular holes and passes through the circular center of the valve plate; the valve rod is welded and fixed with the fixing bases; one end of the valve rod penetrates through the open hole of the valve sleeve and is locked with an external sheath; the other end of the valve rod penetrates out of the circular hole and a shaft sleeve of the valve sleeve. The valve rod is fixed with the valve plate, and through rotation of the valve rod, the valve plate is driven to rotate with the valve rod as a rotating shaft; the valve can be completely opened after the valve plate is rotated for 90 degrees, and on the contrary, the valve can be closed after the valve plate is rotated for 90 degrees in an opposite direction; therefore, the rotationally opening and closing liquid pipeline valve is easy, convenient, time-saving and labor-saving in operation and good in sealing performance, and is applicable to a pipeline for conveying liquid with relatively high pressure intensity.
Description
Technical field
The present invention relates to technical field of valve manufacturing, particularly relate to a kind of rotary opening and closing fluid pipeline valve.
Background technique
In general, want the larger pressure of load for delivery of the pipeline of liquid, for example petroleum transportation pipeline, drinking water conveying pipe road etc., some commercially available pipeline valves, general what adopt is at the valve rod place worm structure to be set, and by rotary valve rod valve plate is opened; As everyone knows, carry the pipeline of liquid easily to cause the valve burn into to get rusty, especially the situation generation of corrosion can appear in the valve of worm structure after long-term the use, and its sealing also reduces greatly; Particularly running into emergency situations when needing throttle down, waste time and energy, easily cause dangerous situation to increase.
Summary of the invention
The objective of the invention is for the technological deficiency that exists in the prior art, and a kind of valve that can pass through rotary valve rod quick closedown fluid pipeline is provided.
For realizing that the technological scheme that purpose of the present invention adopts is: a kind of rotary opening and closing fluid pipeline valve is characterized in that comprising valve pocket, valve plate, valve rod; Described valve pocket has two perforates of passing for valve rod two ends, and tapping is provided with the axle sleeve for righting rotary state valve rod, and another tapping is provided with the overcoat that pins valve rod; Two fixed bases are installed on the described valve plate, are respectively had an identical circular hole of the diameter with described valve rod on the described fixed base, described valve rod passes the center of circle of circular hole and the described valve plate of process; Described valve rod and fixed base are welded and fixed, the one end pass described valve pocket perforate and with described outer cover locking, the other end passes circular hole and the axle sleeve of described valve pocket.
The end that described valve rod passes described axle sleeve one end is provided with square column spinner.
Described valve pocket is provided with the rotary stopper platform at itself and described valve plate joint.
Compared with prior art, the invention has the beneficial effects as follows: valve rod and valve plate are fixed, by rotary valve rod, driven valve plate and rotate take valve rod as rotating shaft, half-twist can be opened valve fully; On the contrary, rotary valve plate is 90 ° in the opposite direction, gets final product throttle down; The valve control operation is easy, and is time saving and energy saving, and good airproof performance is suitable for the liquid conducting pipes of larger pressure.
Description of drawings
Figure 1 shows that the structural representation of valve closing state of the present invention;
Figure 2 shows that the structural representation of valve open state of the present invention;
Figure 3 shows that the structural representation of valve rod end.
Embodiment
Below in conjunction with specific embodiment the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Embodiment:
Be a kind of rotary opening and closing fluid pipeline valve as shown in Figure 1, 2, comprise valve pocket 1, valve plate 2, valve rod 3; Described valve pocket 1 has two perforates of passing for valve rod 3 two ends, and tapping is provided with the axle sleeve 5 for righting rotary state valve rod 3, and another tapping is provided with the overcoat 7 that pins valve rod 3; Two fixed bases 4 are installed on the described valve plate 2, are respectively had an identical circular hole of the diameter with described valve rod 3 on the described fixed base 4, described valve rod 3 passes the center of circle of circular hole and the described valve plate 2 of process; Described valve rod 3 is welded and fixed with fixed base 4, and the one end passes the perforate of described valve pocket 1 and locks with described overcoat 7, and the other end passes circular hole and the axle sleeve 5 of described valve pocket 1.
During use, by rotary valve rod 3, drive valve plate 2 and rotate take valve rod 3 as rotating shaft, half-twist can be opened valve fully; On the contrary, rotary valve plate 2 rotates 90 ° in the opposite direction, gets final product throttle down.
Further, the end that described valve rod 3 passes described axle sleeve 5 one ends is provided with square column spinner 6, and square column spinner 6 and valve rod 3 integrated punching moulding are convenient to control its rotation by external tool.
Further, described valve pocket 1 is provided with the rotary stopper platform at itself and described valve plate 2 joints, and the quantity of rotary stopper platform is preferably 2, so that control respectively the valve plate rotation to the position that opens and closes fully.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
