The utility model discloses a task is accomplished like this, its characterized in that: the pressure sensing rod is arranged inside the adjusting bolt, the guide rod on the pressure sensing rod is inserted into the through hole at the bottom of the adjusting bolt, the pressure sensing spring is arranged inside the adjusting bolt, two ends of the pressure sensing spring are connected with the spring seat on the pressure sensing rod and the inner bottom surface of the adjusting bolt, and the threaded sleeve is in threaded connection with the outer side of the adjusting bolt. The pressure sensing rod comprises a spring seat and a guide rod, the spring seat is cylindrical, the lower surface of the spring seat is spherical, the upper surface of the spring seat is provided with a spring groove, a guide rod mounting blind hole is formed in the center of the spring groove, and the guide rod is of a long and thin cylindrical structure. A washer is installed on the bottom surface inside the adjusting bolt. And a locking nut is arranged on the outer side of the adjusting bolt.
The utility model discloses has following effect: according to the technical scheme, the pressure-sensing spring is utilized to realize the pressure reduction function of the device, and the required pressure can be flexibly adjusted by rotating the adjusting bolt. And the pressure sensing rod in the technical scheme is of a split structure, so that raw materials can be saved in the machining process. The utility model discloses a simple structure can adjust required outlet pressure in a flexible way.
Drawings
FIG. 1 is a schematic structural view of the present invention; fig. 2 is a schematic view of a pressure sensing rod structure.
Description of the drawings: 1. a pressure sensing rod; 1-1. spring seat; 1-2. spring groove; 1-3, installing blind holes; 1-4. guide bar; 2. a pressure-sensitive spring; 3. adjusting the bolt; 4. a threaded sleeve; 5. locking the nut; 6. a gasket; 7. a housing; 8. and a shutter.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in figure 1, the pressure sensing rod device is characterized in that a pressure sensing rod 1 is arranged inside an adjusting bolt 3, guide rods 1-4 on the pressure sensing rod 1 are inserted into a through hole at the bottom of the adjusting bolt, a pressure sensing spring 2 is arranged inside the adjusting bolt 3, two ends of the pressure sensing spring are connected with a spring seat 1-1 on the pressure sensing rod and the inner bottom surface of the adjusting bolt, and a threaded sleeve 4 is sleeved outside the adjusting bolt 3 in a threaded connection mode. The bottom surface of the inner part of the adjusting bolt 3 is provided with a gasket 6 which plays a role of sealing. And a locking nut 5 is arranged on the outer side of the adjusting bolt 3.
As shown in fig. 2, the pressure sensing rod 1 includes a spring seat 1-1 and a guide rod 1-4, the spring seat 1-1 is a cylinder, the lower surface is a spherical surface, the upper surface is provided with a spring groove 1-2, a guide rod installation blind hole 1-3 is arranged at the center of the spring groove 1-2, and the guide rod 1-4 is a slender cylinder structure.
The outer side of the threaded sleeve 4 is provided with threads which can be connected with the shell 7 by threads. After the pressure-sensitive rod device is installed, the bottom end surface of a valve 8 in the shell 7 is contacted with the spherical surface of the spring seat 1-1. When the device works, a medium passes through the shell 7 and then acts on the valve 8, the valve 8 is pressed to apply force to the spring seat 1-1 of the pressure sensing rod 1, and the pressure sensing rod 1 is forced to extrude the pressure sensing spring 2. The pressure sensing spring 2 reacts on the spring seat 1-1 of the pressure sensing rod 1 due to the elasticity of the pressure sensing spring, so that the opening degree of the valve 8 and the inlet of the shell 7 is adjusted, and the outlet pressure is adjusted. If the pressure behind the valve needs to be changed, the adjusting bolt 3 only needs to be rotated.
In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
