Embodiment Construction

[0033] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a new type of quick discharge valve used in a large foaming machine is composed of a vertical main valve body 1, a main piston mechanism 2, a pilot valve body 3, a pilot valve piston 4, a valve cover 5, and a main valve plus The pressure flange 6, the spring, the tee flange 9, the oil return pipe 10, and the vertical core pipe 8 are characterized in that,

[0034] The lower end of the front side of the vertical main valve body 1 is integrally formed with the first oil port 11 connected to the main oil cylinder, the lower end of the right side of the vertical main valve body 1 is integrally formed with the second oil port 12, and a pipe of the horizontal oil pipe 13 One end communicates with the second oil port 12, and the other end of the transverse oil pipe 13 communicates with the oil tank;

[0035] The inside of the vertical main valve body 1 is integrally formed with a vertical oil chamber, the first ...

Abstract

The invention discloses a novel rapid discharging valve applied to a large foaming machine. Pressure guide oil enters a first oil cavity and a second oil cavity of a pilot valve body through a pilot pressure guide channel, a pilot valve piston moves upwards under the pushing effect of the pressure guide oil till a channel between an oil passing groove and a first valve element hole is completely sealed and blocked, at the moment, a rapid hydraulic oil discharging channel is in a closed state, when the rapid hydraulic oil discharging channel is opened, the pressure guide oil in the first oil cavity and the second oil cavity is discharged through the pilot pressure guide channel, at the moment, the pilot valve piston moves downwards under the action of a first spring, the channel between theoil passing groove and the first valve element hole is rapidly opened, the hydraulic oil, located above a main piston mechanism, in a vertical oil cavity is rapidly discharged through the rapid hydraulic oil discharging channel, and therefore the ascending speed of the main piston mechanism is effectively increased. The novel rapid discharging valve applied to the large foaming machine has the characteristics of being novel in structure, higher in pressure relief speed and higher in practicability.

Description

technical field [0001] The invention belongs to the field of large foaming machine accessories, in particular to an EVA foaming machine, and relates to a novel quick-discharging valve applied in a large foaming machine. Background technique [0002] The quick discharge valve in the existing large foaming machine will have the problem of slow pressure relief, which will not only affect the working efficiency of the hydraulic system of the large foaming machine, but also affect the foaming quality of the large foaming machine . Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of quick discharge valve applied in large foaming machines. The present invention has the characteristics of novel structure, faster pressure relief speed and stronger practicability. [0004] In order to achieve the above object, the present invention adopts the following specific technical measures: a new type of quick discharge valve ...
