Problems solved by technology

[0003] However, since the new type of filter has two functions of gas-water separator and high-efficiency filter, it has two upper and lower working chambers. The lower working chamber has the function of gas-water separator, and the upper working chamber has the function of high-efficiency filter.

Embodiment Construction

[0012] Such as Figure 1 to Figure 3 As shown, in the present invention, the present invention includes a sewage guide sleeve 1, a spring 2, a sealing float 3, and a sewage cover 4. The sewage guide sleeve 1 is provided with a spring mounting surface 13, and the spring 2 is arranged on the spring. On the installation surface 13, the sealing float 3 is arranged between the sewage guide sleeve 1 and the sewage cover 4, and the sewage guide sleeve 1 is also provided with a sewage guide sleeve guide hole 11 and a sewage guide sleeve drain hole 12. The drain cover 4 is provided with a drain cover sealing surface 41 and a drain cover drain hole 42.

[0013] Principle: When working, when compressed air enters the filter through the filter inlet on the multi-function filter tube head, it is processed by the air-water separation device first, and a large amount of liquid water falls on the slope at the bottom of the tube body and flows into the slope. The bottom of the sewage outlet; the...

Abstract

The invention discloses a blow-down valve, aims to provide a driven sealing floating ball blow-down valve and belongs to the technical field of filtering and sewage blowing-down. The driven sealing floating ball blow-down valve comprises a blow-down guide sleeve (1), a spring (2), a sealing floating ball (3) and a blow-down cover (4), wherein the blow-down guide sleeve (1) is provided with a spring installation surface (13); the spring (2) is arranged on the spring installation surface (13); and the sealing floating ball (3) is arranged between the blow-down guide sleeve (1) and the blow-down cover (4).

Description

Technical field [0001] The invention relates to a sewage valve, in particular to a driven sealing float ball sewage valve. Background technique [0002] In the prior art, the air-water separator and the high-efficiency filter in the compressed air filter have only one working chamber, and only one blowdown valve is needed to control the blowdown port to solve the blowdown problem. The existing blowdown valve generally has a mechanical blowdown valve and an electric control. Two types of blowdown valves. The working principle of the mechanical drain valve is: when the filter condensate and oil reach a certain amount, the drain will automatically open due to the effect of buoyancy, and then automatically close after the liquid level drops to achieve the automatic drain function. The working principle of the electronically controlled drain valve is: install a normally closed solenoid valve at the filter drain port, and control its opening and closing by an electronic controller to ...
