The utility model discloses a cavity, its characterized in that: an installation platform is arranged on the side of the cavity, an oil discharge hole communicated with the cavity is formed in the installation platform, and threaded blind holes are formed in the periphery of the oil discharge hole; an oil discharge flange is fixed on the mounting platform through the matching of a bolt assembly and a threaded blind hole; the oil discharge flange is provided with a pipe joint corresponding to the oil discharge hole, and the pipe joint is connected with an oil discharge pipe with a ball valve.
Description
Technical Field
The utility model relates to a flange formula oil extraction structure of three jars single-action diaphragm pump fluid end cavity.
Background
The hydraulic end of the three-cylinder single-action diaphragm pump comprises a feeding and discharging pipe, a diaphragm chamber, a cavity, an oil cylinder, a nitrogen bag, fasteners of different specifications and the like. The cavity and the oil cylinder are used as one of the key parts of the hydraulic end, the interior bears the working pressure of the propelling liquid oil, and the piston reciprocates in the cylinder sleeve.
In the regular maintenance process of the three-cylinder single-action diaphragm pump, the mode of drilling a threaded hole at the lower end of the cavity and installing a hexagonal plug screw is adopted for oil discharge of the cavity in the traditional structure, but the structure has a great problem.
Firstly, the hexagonal plug is slow in oil discharging speed, so that the on-site maintenance efficiency of a user is influenced; secondly, the hexagonal plug screw is assembled and disassembled for many times, or the internal thread of the cavity is damaged, so that the service life of the cavity is influenced; in addition, the hexagonal plug structure lacks secondary protection, if the seepage easily causes the pollution on user's scene ground, influences the sanitation of diaphragm pump operation scene.
Disclosure of Invention
The utility model is directed to the above problem, the utility model provides a novel flange formula oil extraction structure, this kind of structure is particularly useful for the cavity and the hydro-cylinder of large-traffic three-cylinder single action diaphragm pump, can obviously accelerate oil extraction efficiency when the propulsion liquid oil mass is great, and female screw-thread machining in flange department, can ensure the life of fluid end pressure-bearing cavity.
In order to realize the above object of the utility model, the utility model discloses a following technical scheme, the utility model discloses a cavity, its characterized in that: the side of the cavity is provided with an installation platform, the installation platform is provided with an oil discharge hole communicated with the inside of the cavity, and threaded blind holes are formed in the periphery of the oil discharge hole; an oil discharge flange is fixed on the mounting platform through the matching of a bolt assembly and a threaded blind hole; and a pipe joint corresponding to the oil discharge hole is arranged on the oil discharge flange and is connected with an oil discharge pipe with a ball valve.
As an optimal scheme of the utility model, be provided with the metal winding pad between oil extraction flange and the mounting platform.
As another preferred scheme of the utility model, oil extraction pipe one end is connected with the coupling, and the oil extraction pipe other end is provided with the plug.
The utility model has the advantages that: 1. simple structure, convenient processing and low cost. The utility model relates to a part only need utilize the rod unloading in the production and processing process can, the cost is lower, and fastener and ball valve all can be purchased outward, and the installation is dismantled and the on-the-spot maintenance is comparatively simple and convenient.
2. Good stability and low failure rate. The utility model discloses in, oil extraction flange, winding pad, fastener are disposable installation, only need open the ball valve during the oil extraction, and need not operate other spare parts, do not have the condition of locking many times and opening hexagonal plug screw in traditional structure yet.
3. Is beneficial to keeping clean on site. The utility model provides a plug lock is terminal in the oil extraction pipe, can effectively prevent the seepage of propulsion liquid oil, keeps the scene clean and clean.
