Abstract

The utility model relates to a stroke-adjustable pressure relief functional valve group and a roll squeezer, comprising a functional valve body and a main valve core arranged in the functional valve body, wherein the functional valve body is provided with an adjustable stroke limiting rod, a pilot valve and an overflow valve, the adjustable stroke limiting rod is abutted with the main valve core and used for propping and sealing the main valve core, the overflow valve is arranged on one side of the functional valve body and connected with the main valve core and used for setting the safety pressure of the main valve core, and the pilot valve is arranged on one side of the functional valve body and connected with the main valve core and used for relieving pressure. The method is mainly used for realizing rapid fault reason judgment aiming at the design and development of the hydraulic system of the roller press equipment in the cement industry, effectively solving the problems of overflow and leakage point fault detection of the main oil cylinder, judging the fault without stopping the roller press, and improving the stopping and overhauling efficiency of the roller press.

Description

Stroke-adjustable pressure relief functional valve group and roller press
Technical Field
The utility model relates to the technical field of hydraulic systems, in particular to a stroke-adjustable pressure relief functional valve group and a roller press with the same.
Background
The original pressure relief valve set of the roller press has only one electromagnetic overflow valve function and no adjustable stroke adjusting rod function, so that when the equipment has internal leakage fault, the fault cause cannot be effectively judged in time, and the roller press needs to be stopped for maintenance, thereby being very inconvenient.
Disclosure of Invention
The utility model aims to provide a stroke-adjustable pressure relief functional valve group and a roller press with the same, which can improve the shutdown maintenance efficiency of the roller press.
The utility model is realized by the following technical scheme:
the utility model provides an adjustable stroke pressure release functional valve group, includes the functional valve body and sets up in the internal main valve core of functional valve, be provided with adjustable stroke limit pole, pilot valve and overflow valve on the functional valve body, adjustable stroke limit pole and main valve core looks butt for with main valve core withhold sealedly, the overflow valve sets up in functional valve body one side and links to each other with the main valve core for set for the relief pressure of main valve core, the pilot valve sets up in functional valve body one side and links to each other with the main valve core, is used for the pressure release.
The utility model also provides a roller press which is provided with the stroke-adjustable pressure relief functional valve group.
The beneficial effects of the utility model are as follows: the method is mainly used for realizing rapid fault reason judgment aiming at the design and development of the hydraulic system of the roller press equipment in the cement industry, effectively solving the problems of overflow and leakage point fault detection of the main oil cylinder, judging the fault without stopping the roller press, and improving the stopping and overhauling efficiency of the roller press.
Drawings
FIG. 1 is a schematic view of the external three-dimensional structure of a valve set with an adjustable stroke pressure relief function according to the present utility model;
fig. 2 is an internal schematic diagram of the adjustable stroke relief valve block of the present utility model.
Detailed Description
The preferred embodiments of the present utility model will be described in detail below with reference to the attached drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
Example 1:
the utility model provides an adjustable stroke pressure release functional valve group as shown in figure 1, includes functional valve body 1 and sets up the main valve core in functional valve body 1, be provided with adjustable stroke restriction pole 2, pilot valve 4 and overflow valve 3 on the functional valve body 1, adjustable stroke restriction pole 2 and main valve core looks butt for with main valve core withstand seal, overflow valve 3 sets up in functional valve body 1 one side and links to each other with the main valve core for set for the relief pressure of main valve core, pilot valve 4 sets up in functional valve body 1 one side and links to each other with the main valve core for the pressure release.
Specifically, as shown in fig. 2, hydraulic oil of a main port P acts on the main valve core 5, meanwhile, the hydraulic oil passes through a control oil path of an port X and passes through a 2-combination overflow functional cover plate, when the pressure value of the port P exceeds a set value, the overflow valve 3 opens a return port T, so that the pressure of the port P is kept at the set pressure of the overflow valve 3 to supply oil in a working manner; the functional valve group can also work through the pilot valve 4, so that the main valve core 5 is opened to realize unloading function, and the oil pressure of the P port directly realizes unloading through the T port; the functional valve group can also realize that the main valve core 5 is propped against and sealed through the adjustable stroke limiting rod 2, so that the oil liquid at the P port does not pass through the T port, and whether the main valve core has internal leakage or not is judged.
Example 2:
the embodiment provides a roll squeezer for cement trade, this roll squeezer be furnished with adjustable stroke pressure release functional valve group of embodiment 1, mainly solves the realization roll squeezer and does not shut down the trouble and judge, promotes to shut down maintenance efficiency.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
