Problems solved by technology

[0002] During the glue filling operation of the two-component screw valve, due to the narrow and long flow path of the product, the flow resistance of the glue in the product cavity increases, which in turn leads to a high and unstable pressure at the outlet of the screw valve
Since the volumetric efficiency of the screw valve is strongly related to the output pressure of the screw valve, the output pressure of the screw valve will have a great impact on the glue output and precision of the screw valve, thus losing the advantage of high-precision quantitative dispensing

Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] See Figure 1-12 , a two-component screw valve with constant pressure output of the present invention has a stator fixing seat 2 for fixing the stator 1, and the stator fixing seat 2 is provided with two stator outlets 3 and two valve body outlets 4, a stator The outlet 3 corresponds to a valve body outlet 4, and the corresponding stator outlet 3 and the valve body outlet 4 are connected by a flow channel 5, and a pressure adjustment mechanism is arranged in the flow channel 5, so that the glue passes through the pressure adjustment mechanism first and then flows ...

Abstract

The invention discloses a constant-pressure output two-component screw valve. The constant-pressure output two-component screw valve is provided with a stator fixing seat used for fixing a stator; the stator fixing seat is provided with two stator outlets and two valve body outlets; one stator outlet corresponds to one valve body outlet; the stator outlets and the valve body outlets which correspond to each other are connected through flow channels; and pressure adjusting mechanisms are arranged in the flow channels, so that glue passes through the pressure adjusting mechanisms firstly and then flows out of the valve body outlets of the screw valve. According to the constant-pressure output two-component screw valve, the pressure of the glue flowing out of a screw valve body is consistent, constant-pressure output is achieved, and the influence of resistance of a product cavity or a small-diameter needle head on the glue outlet amount of the screw valve is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of two-component screw valves, in particular to a two-component screw valve with constant pressure output. Background technique [0002] During the glue filling operation of the two-component screw valve, due to the narrow and long flow path of the product, the flow resistance of the glue in the product cavity increases, which in turn leads to a high and unstable pressure at the outlet of the screw valve. Since the volumetric efficiency of the screw valve is strongly related to the output pressure of the screw valve, the output pressure of the screw valve will have a great impact on the glue output and precision of the screw valve, thus losing the advantage of high-precision quantitative dispensing. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, the present invention proposes a two-component screw...
