Problems solved by technology

[0003] At present, most of the suction cups on the market are controlled by three-way valves to realize negative pressure suction control. The disadvantages of the products are that the aperture flow is limited, and secondly, the pressure release is slow and delayed, and the cost price is slightly higher and the structure is complicated.

Embodiment 1

[0017] A simple negative pressure valve combination, which consists of: a vacuum pump 1, a vacuum filter 2, an air control valve A5 and an air control valve B8, the vacuum pump is connected to the vacuum filter through a threaded structure, and the vacuum The filter is connected to the food pipeline 4 through the leather tube joint 3, the end of the food pipeline is connected to one end of the air control valve A, and the other end of the air control valve A is connected to the three The straight-through structure of the three-way thread is connected to the food pipeline through the threaded thread B9, and the elbow structure of the three-way thread is connected to the gas pipeline through the threaded thread A. Control valve B connection.

Embodiment 2

[0019] According to the simple negative pressure valve combination described in Example 1, the food pipeline connected to the control valve A is fixedly connected to the pipe collar of the vacuum filter tube, and the food pipeline is connected to the 1-inch The wire thread B is fixedly connected by a pipe collar, and the wire thread A is connected 1 inch to the tee thread.

Embodiment 3

[0021] According to the simple negative pressure valve combination described in embodiment 1 or 2, two straight-through valve branches are combined into a simple negative pressure valve, wherein the main circuit is connected to the negative pressure source, which is in a normally closed state, and is connected by the three-way thread Leading out the branch, the inlet end is connected to positive pressure compressed air, which is normally closed.

Abstract

The invention relates to a simple negative-pressure valve combination and an adjusting method. At present, on the market, mostly, three-way valve control is adopted for achieving negative-pressure airsuction, suction cups are controlled, the limited hole diameter circulation amount is the product defect, in addition, pressure releasing is slow and is delayed, the cost price is slightly high, andthe structure is complex. The simple negative-pressure valve combination comprises a vacuum pump (1), a vacuum filter (2), an air control valve A (5) and an air control valve B (8). The vacuum pump isconnected with the vacuum filter through a threaded structure. The vacuum filter is connected with a food pipeline (4) through a leather pipe connector (3). The end portion of the food pipeline is connected with one end of the air control valve A, and the other end of the air control valve A is connected with a three-way thread (7) through a double nipple thread A (6), a straight through structure of the three-way thread is connected with the food pipeline through a double nipple thread B (9), and a bend structure of the three-way thread is connected with the air control valve B through the double nipple thread A. The simple negative-pressure valve combination is applied.

Description

Technical field: [0001] The invention relates to a simple negative pressure valve combination and an adjustment method. Background technique: [0002] The negative pressure valve includes a valve body, a valve cover, and an opening device. The valve body is provided with a water inlet hole and a water outlet hole. [0003] At present, most of the suction cups on the market are controlled by three-way valves to achieve negative pressure suction control. The disadvantages of their products are limited aperture flow, secondly, slow and delayed pressure relief, and the cost price is slightly higher and the structure is complicated. Invention content: [0004] The purpose of the present invention is to provide a simple negative pressure valve combination and adjustment method. [0005] Above-mentioned purpose realizes by following technical scheme: [0006] A simple negative pressure valve combination, which consists of: a vacuum pump, a vacuum filter, an air control valve A ...
