Description

Technical Field

[0001] The utility model belongs to the technical field of valve bodies, and particularly relates to a porous valve body. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to the functions of the valve, it can be divided into a shut-off valve, a check valve, a regulating valve, etc. The valve body is a main component in the valve; there are different mechanical manufacturing methods according to the pressure grade.

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: The valve bodies in the prior art (such as the patent with the application number CN202123026236.7 - a high - pressure - resistant porous aluminum valve body) usually do not have a structure for fixedly connecting with external facilities through parts such as bolts and nuts, resulting in poor stability.

[0004] Therefore, we propose a porous valve body to solve the above problems. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a porous valve body, which is more convenient to install, and by installing the valve body through the above - mentioned scheme, its structure can be made more stable, and the problems in the background art can be effectively solved.

[0006] To achieve the above purpose, the present utility model adopts the following technical scheme:

[0007] A porous valve body includes a main body and a protective shell fixedly sleeved outside the main body. The protective shell is used to protect the main structure of the main body. A set of positioning mechanisms are respectively arranged on two opposite sides of the main body. The positioning mechanism includes two outer brackets welded on the protective shell. One side wall of each of the two outer brackets is rotatably connected with a first knob, and mounting grooves are formed on the bottom walls of the two outer brackets;

[0008] First screws are coaxially connected to the two first knobs respectively. Slide seats are respectively sleeved on the two first screws in a threaded manner, and the two slide seats are respectively attached to the inner walls of the two mounting grooves, so that when the first screws rotate, they can drive the slide seats to translate along the inner walls of the mounting grooves. Second knobs are respectively rotatably connected to the bottom walls of the two slide seats, and inner driving chambers are respectively formed above the second knobs inside the two slide seats. Two bevel gears meshing with each other are arranged in the inner driving chambers, and inner support shafts are respectively coaxially connected to the two bevel gears;

[0009] The two second knobs are respectively coaxially connected to one of the inner support shafts in the two inner drive chambers. The other inner support shafts in the two inner drive chambers are respectively coaxially connected with second screws. Side grooves are respectively formed on the sides of the two sliding seats facing away from the protective shell. Piston blocks are respectively sleeved on the two second screws in a threaded manner, and the two piston blocks are respectively in contact with the inner walls of the two side grooves. Positioning seats are respectively welded on the sides of the two piston blocks facing away from the protective shell. Threaded holes for installing bolts are tapped on the positioning seats. A total of four threaded holes are provided on both sides of the protective shell, so as to facilitate fixing the main body and the protective shell to a specified structure in the outside world through four groups of bolts. In actual design, the number of threaded holes can be more, so as to facilitate making the fixation of the main body and the protective shell firmer.

[0010] Preferably, an input port and an output port are respectively provided on both sides of the main body; the input port is used for inputting fluid, and the output port is used for outputting fluid. The technical principle of the main body is the prior art.

[0011] Preferably, the first screw is horizontally arranged in the installation groove, and the first screw is rotationally connected to the outer bracket; so that the first screw can operate stably in the installation groove.

[0012] Preferably, the two inner support shafts in the inner drive chamber are perpendicular to each other, and both inner support shafts are rotationally connected to the sliding seat; so that the inner support shafts and the bevel gears thereon can operate stably.

[0013] Preferably, the second screw is horizontally arranged in the side groove, and the second screw is rotationally connected to the sliding seat; so that the second screw can operate stably.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] For this porous valve body, by rotating the first knob to drive the two bevel gears connected thereto to operate, the positioning seat above can be adjusted to translate in one direction. By rotating the second knob, the positioning seat can be driven to translate in another direction, so that it can be moved to a specified position and used to be fixed to other structures in the outside world through bolts. Since the position of the positioning seat can be adjusted in two different directions, it has a wider installation range, that is, it is more convenient to install. By installing the valve body through the above solution, its structure can be made more stable;

[0016] For this porous valve body, rotating the first knob drives the first screw connected thereto to operate, so that the sliding seat translates along the inner wall of the installation groove and drives the positioning seat to translate in one direction. Subsequently, rotating the second knob drives the two bevel gears and the two inner support shafts to operate, so that the second screw operates accordingly and drives the piston block and the positioning seat to translate, so that the positioning seat translates in another direction. Finally, the positioning seat is correspondingly attached to the fixed structure, so as to facilitate fixing the two with bolts and nuts, making its structure firmer than the prior art.

[0022] Refer to Figures 1 - 3 , a porous valve body, comprising a main body 1 and a protective shell 2 fixedly sleeved outside the main body 1. An input port 3 and an output port 4 are respectively arranged on both sides of the main body 1. The input port 3 is used for inputting fluid, and the output port 4 is used for outputting fluid. The technical principle of the main body 1 is the prior art. The protective shell 2 is used to protect the structure of the main body 1. A set of positioning mechanisms are respectively arranged on the opposite sides of the main body 1. The positioning mechanism includes two outer brackets 5 welded to the protective shell 2. One side wall of each of the two outer brackets 5 is rotatably connected with a first knob 6. Installation grooves 7 are formed on the bottom walls of the two outer brackets 5;

[0023] The two first knobs 6 are respectively coaxially connected with a first screw 8. The first screw 8 is horizontally arranged in the installation groove 7, and the first screw 8 is rotatably connected with the outer bracket 5, so that the first screw 8 can stably operate in the installation groove 7. Slide seats 9 are respectively sleeved on the two first screws 8 by threads, and the two slide seats 9 are respectively attached to the inner walls of the two installation grooves 7, so that when the first screw 8 operates, it can drive the slide seat 9 to translate along the inner wall of the installation groove 7. Second knobs 10 are respectively rotatably connected to the bottom walls of the two slide seats 9, and inner driving chambers 11 are respectively formed above the second knobs 10 inside the two slide seats 9. Two meshing bevel gears 12 are arranged in the inner driving chamber 11, and two inner support shafts 13 are respectively coaxially connected to the two bevel gears 12. The two inner support shafts 13 in the inner driving chamber 11 are perpendicular to each other, and both of the two inner support shafts 13 are rotatably connected with the slide seat 9, so that the inner support shaft 13 and the bevel gear 12 thereon can stably operate;

[0024] The two second knobs 10 are respectively coaxially connected to one of the inner support shafts 13 in the two inner drive chambers 11. The other inner support shafts 13 in the two inner drive chambers 11 are respectively coaxially connected with second screw rods 15.
