Embodiment 1

[0027] Such as Figures 1 to 12 , the spray valve of this embodiment includes: a valve body 1, two valve cores 2 respectively movably fitted in the two piston cavities 1-1 of the valve body 1, and connecting grooves connected to the upper end surfaces of each valve core 2. Two hollow valve rods 3 for controlling the up and down displacement of each valve core 2 in the corresponding piston chamber 1-1, and the valve rod 3 provided on the top port of each piston chamber 1-1 for sealing and matching with the top of the corresponding valve core 2 sealing ring 4; each valve rod 3 is in sliding and sealing cooperation with the sealing ring 4, and / or each valve rod 3 is in sliding and sealing cooperation with the sealing cover 5 arranged above the sealing ring 4; each piston chamber 1-1 1. A spring 9 is arranged at the bottom of each valve core 2; a valve body joint 1-2 is connected to the bottom of each piston chamber 1-1; each valve body joint 1-2 is respectively connected with a c...

Embodiment 2

[0033] On the basis of Embodiment 1, there are the following modifications in this embodiment:

[0034] The valve body joint 1-2 of the valve body 1 is sealed and connected in a high-pressure gas tank 7 .

Embodiment 3

[0036] On the basis of embodiment 1 or 2, there are the following modifications in this embodiment:

[0037] Adjacent sub-buttons are slidably matched with each other through sliding grooves that can limit each other, so that the buttons have integrity, thereby improving their reliability in use, and preventing a sub-button from swinging randomly during use to affect the use. Extended service life.

[0038] The middle and upper parts of the adjacent valve stems 3 are slidably matched with each other through sliding slots that can limit each other, so that each valve stem 3 has integrity, thereby improving its reliability in use, and preventing a certain valve stem from swinging randomly during use. Affect the use of the situation, prolong its service life.

Abstract

The invention relates to a multi-valve spraying valve. The spraying valve comprises an outer valve body, an inner valve body moveably arranged in the outer valve body, and a hollow valve body arranged in the inner valve body; when the inner valve body is moved downwards in relative to the outer valve body through the valve rod, an overflow slot on the inner wall beneath the middle part of the outer valve body is interconnected with an overflow through hole in the middle part of the wall body of the inner valve body, and further connected with a radial through hole at the bottom part of the valve rod; and thereby, the continuous spraying or filling function is realized.

Description

technical field [0001] The invention relates to a multi-valve body spray valve. Background technique [0002] The existing spray valve has only one spray port, and can only spray the liquid in one container. In special applications, for example, it is not possible to mix multiple liquid medicines or glues in advance, it is often necessary to spray out the liquids in multiple containers at the same time and mix them by spraying. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a multi-valve spray valve with simple structure and convenient filling, which can simultaneously spray liquids in multiple containers and mix them by spraying. [0004] In order to solve the above-mentioned primary technical problem, the present invention provides a spray valve, which includes: a valve body, a plurality of valve cores respectively movably fitted in multiple piston cavities of the valve body, and plug-in connections wit...
