Abstract
The invention discloses a constant-pressure pipe joint. Two joints of the same kind are respectively installed at the two ends of a round pipe through a threaded connecting method. A slide valve is installed in the internal part of one end of the round pipe. A steel ball and a pressure spring are sequentially installed in a cavity in the slide valve. A bonnet fixes the steel ball and the pressure spring in the cavity in the slide valve. A constant-pressure spring which is connected with one end of the slide valve in the round pipe is arranged. A pressure relief hole is arranged in the wall of the round pipe. In a free state, the slide valve blocks the pressure relief hole; when fluid flows in the round pipe from the joint at the left end, the pressure of the fluid thrusts away the steel ball and the fluid flows out from the joint at the other end through the round pipe; and if the rated pressure is exceeded, the slide valve moves rightwards, high pressure is relieved through the pressure relief hole and the pressure is guaranteed to be in a basically constant state. The constant-pressure pipe joint can be directly connected with an actuating element, the actuating element can obtain constant pressure without additionally arranging other elements, and the defects that the cost is higher and the structure of the entire hydraulic or pneumatic system is not compact enough because corresponding other pneumatic or hydraulic elements are additionally arranged in a pipeline are overcome.
Description
Technical field
The present invention relates to a kind of pipe joint of pneumatic or hydraulic element technology, is a kind of constant-pressure formula pipe joint specifically.
Background technique
At present, in pneumatic or hydraulic pipe line, pipe joint is only as the intermediary element that is communicated with, if make executive component obtain constant pressure, must in pipeline, set up corresponding other pneumatic or hydraulic element, this just not only causes cost higher, simultaneously, also can make the structure of whole hydraulic pressure or pneumatic system compact not.
Summary of the invention
The object of the invention is to: a kind of constant-pressure formula pipe joint is provided, this kind constant-pressure formula pipe joint can directly link to each other with executive component, need not to set up other element, just can make executive component obtain constant pressure, overcome and set up corresponding other pneumatic or hydraulic element in the pipeline, cause cost higher, also can make the compact not defective of structure of whole hydraulic pressure or pneumatic system.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: this invention comprises joint, pipe, guiding valve 3, steel ball, valve gap, pressure spring, the level pressure spring, relief hole, a kind of joint is installed respectively by the mode of screw thread in two ends at pipe, inside at pipe one end is equipped with guiding valve, steel ball is installed in the cavity of guiding valve inside successively, pressure spring, valve gap is with steel ball, pressure spring is fixed in the cavity of guiding valve inside, be provided with a level pressure spring that in pipe, is connecting at guiding valve one end, be provided with relief hole at the pipe wall, under free state, guiding valve blocks relief hole; When fluid flows into from the joint of left end, the pressure of fluid is washed steel ball open, fluid flows through by the joint of pipe from an other end, if during over proof pressure, guiding valve moves right, high pressure flows through from relief hole, guarantee that pressure is in the substantially constant state, the present invention can directly link to each other with executive component, need not to set up other element, just can make executive component obtain constant pressure, overcome and set up corresponding other pneumatic or hydraulic element in the pipeline, cause cost higher, also can make the compact not defective of structure of whole hydraulic pressure or pneumatic system.
Beneficial effect of the present invention: the present invention need not to set up other element, just can make executive component obtain constant pressure, overcome and set up corresponding other pneumatic or hydraulic element in the pipeline, cause cost higher, also can make the compact not defective of structure of whole hydraulic pressure or pneumatic system.
Description of drawings
Accompanying drawing 1 is structure principle chart of the present invention..
Shown in the figure: 1 joint, 2 pipes, 3 guiding valves, 4 steel balls, 5 valve gaps, 6 pressure springs, 7 level pressure springs, 8 relief holes.
Embodiment
In the drawings, this invention comprises joint 1, pipe 2, guiding valve 3, steel ball 4, valve gap 5, pressure spring 6, level pressure spring 7, relief hole 8, a kind of joint 1 is installed respectively by the mode of screw thread in two ends at pipe 2, inside at pipe 2 one ends is equipped with guiding valve 3, in the cavity of guiding valve 3 inside steel ball 4 is installed successively, pressure spring 6, valve gap 5 is with steel ball 4, pressure spring 6 is fixed in the cavity of guiding valve 3 inside, be provided with one at the pipe 2 interior level pressure springs 7 that connecting guiding valve 3 one ends, be provided with relief hole 8 at pipe 2 walls, under free state, guiding valve 3 blocks relief hole 8; When fluid flows into from the joint of left end, the pressure of fluid is washed steel ball 4 open, fluid flows through by the joint of pipe 1 from an other end, if during over proof pressure, guiding valve 3 moves right, high pressure flows through from relief hole 8, guarantee that pressure is in the substantially constant state, the present invention can directly link to each other with executive component, need not to set up other element, just can make executive component obtain constant pressure, overcome and set up corresponding other pneumatic or hydraulic element in the pipeline, cause cost higher, also can make the compact not defective of structure of whole hydraulic pressure or pneumatic system.
