Technical Field

The utility model relates to a lubricating system field, concretely relates to emollient distributor.

Background

In order to reduce the wear between the moving parts of mechanical equipment (including passenger car chassis, engineering vehicle, dock machinery, metallurgical equipment, wind power generation equipment, etc.) and maintain good running state between mechanisms, people must regularly oil and lubricate the moving parts in the mechanical equipment. The lubricating system in the prior art is generally divided into a single-line damping type lubricating system, a progressive type lubricating system and a volumetric type lubricating system, wherein the progressive type lubricating system is widely applied due to the characteristics that the progressive type lubricating system can convey a plurality of lubricating points, is convenient to use and can also use grease as lubricating oil. Such progressive lubrication systems generally comprise pump stations, controllers and progressive dispensers, and usually a lubricant pump automatically, periodically and quantitatively supplies lubricant to each lubrication point through the dispenser. However, the existing distributor generally has the problems of complex structure, poor stability, inconvenient control, poor applicability and the like.

Therefore, it is a problem to be solved by those skilled in the art to improve the existing lubrication system distributor to overcome the above disadvantages.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, stability is good, and the integral distributor of discharge capacity but independent assortment.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a unitary dispenser, characterized by: the valve comprises a valve body, wherein at least three groups of valve core assemblies are arranged in the valve body;

the valve body is provided with an oil inlet, and the oil inlet is suitable for being connected with an oil inlet joint;

the valve core assembly comprises two oil outlets arranged on the left side and the right side of the valve body and a valve core cavity arranged in the valve body; the oil outlet is suitable for being connected with an oil outlet joint or an oil outlet plug, and a three-step valve core is arranged in the valve core containing cavity in a sliding mode along the left and right directions; the valve core cavity is communicated with the oil inlet through an annular groove, and the oil outlets on the left side and the right side can be opened and closed by sliding the valve core left and right; the valve core assemblies are communicated through annular grooves.

Preferably, the valve core accommodating cavity penetrates through the valve body, and valve core plugs are arranged at two ends of the valve core accommodating cavity. The valve core containing cavity is convenient to machine and form, and the valve core is convenient to install.

Preferably, the oil outlet joint is a one-way valve joint.

Compared with the prior art, the utility model has the advantages of: 1. the internal oil duct of this scheme is simplified, and does not need other auxiliary spring's mechanism, can reduce the internal pressure loss. 2. Hydraulic pressure automatic drive divides oil in this scheme, and it is stable to produce oil, and accurate oil feeding, single line oil extraction assurance is high. 3. The internal returnable mechanism facilitates free combination of discharge capacity (one or more oil outlets can be combined at will). This scheme is particularly suitable for high pressure high viscosity grease output.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the orientation words, if there are terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and positional relationship indicated are based on the orientation or positional relationship shown in the drawings, and only for the convenience of describing the present invention and simplifying the description, it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and not be construed as limiting the specific scope of the present invention.

As shown in fig. 1 to 8, the present invention is a preferred embodiment of the present invention, and includes a valve body 1, at least three sets of valve core assemblies 100 are disposed in the valve body 1; an oil inlet 11 is formed in the valve body 1, and the oil inlet 11 is suitable for being connected with the oil inlet connector 2; the valve core assembly 100 comprises two oil outlets 12 arranged on the left side and the right side of the valve body 1 and a valve core cavity 13 arranged in the valve body 1; the oil outlet 12 is suitable for being connected with an oil outlet joint 3 or an oil outlet plug 4, and a three-step valve core 5 is arranged in the valve core cavity 12 in a sliding mode along the left and right direction; the valve core cavity 13 is communicated with the oil inlet 11 through an annular groove, and the left and right sliding of the valve core 5 can open and close the oil outlets 12 on the left and right sides; the valve core assemblies 100 are communicated with each other through annular grooves. Wherein, the valve core accommodating cavity 13 penetrates through the valve body 1, and valve core plugs 6 are arranged at two ends of the valve core accommodating cavity 13. In this embodiment, the oil outlet joint 4 is a check valve joint.

The integral distributor of the embodiment belongs to a block type progressive distributor, namely, each progressive distributor consists of a starting valve core, a stopping valve core and at least one middle valve core, the number of the middle valve cores can be N (N is a natural number not less than 1) in theory, and the integral distributor can be designed according to the requirements of customers. But no matter the number of the intermediate valve cores, the intermediate valve cores can be combined with the initial valve core and the final valve core into a whole. This embodiment shows a three spool assembly dispenser, i.e., a start spool, an end spool, and an intermediate spool, but does not preclude embodiments of the present invention that include other numbers of intermediate spools.

As shown in fig. 7 and 8, the working principle of the dispenser is shown, as follows:

the lubricant enters from the oil inlet at the upper part, passes through the annular groove, reaches the left ends of the valve cores II and III and pushes the valve cores II and III to move rightwards, so that the lubricant in the valve core cavity is discharged from the oil outlets E1 and E2 in sequence. And when the valve core III reaches the extreme position of the right end, the lubricant entering the distributor reaches the right end of the valve core I through the annular groove on the left side, and pushes the valve core I to move leftwards, so that the lubricant in the valve core cavity is discharged from the oil outlet E3. Similarly, when the three valve spools move in opposite directions, the corresponding lubricant is discharged from oil outlets E4, E5, and E6 in sequence.

It is worth mentioning that as long as the lubricant entering the progressive distributor maintains a certain pressure, the oil outlet merging mechanism arranged inside the distributor can directly merge and discharge a proper flow rate inside according to the requirement of a customer.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
