Abstract
The utility model relates to a cabin discharge valve, including the valve body, the system has an intake channel of being connected with cabin vent pipe on the valve body, has the exit channel who communicates with the intake channel in the lateral wall system of valve body, sets up the disk seat between intake channel and exit channel, mainly be that the intake channel passes through annular valve pocket and disk seat up end intercommunication, it has cylindrical valve pocket to make between the terminal surface under exit channel and the disk seat, annular valve pocket around the integrative casting shaping in the outer face of cylinder of cylindrical valve pocket, bottom surface system at cylindrical valve pocket has the concave spherical surface, and the floater is placed to the centre of sphere of this concave spherical surface in the concave spherical surface on the disk seat central line, and the floater adopts the stainless steel clean shot. When the air pump exhausted to the cabin, inlet channel of the valve body production negative pressure was inhaled the floater and the valve seat seal cooperation, prevented the air to form the convection current passageway from discharge valve entering cabin and air pump export, and its exhaust is effectual. Be applicable to the discharge valve of cabin gas vent.
Description
Technical field
The utility model belongs to valve field.The utility model is applicable to the outlet valve of cabin relief opening.
Background technique
On boats and ships, be connected with in cabin and lead to extraneous breather line, gas in cabin is discharged into out of my cabin, keep the air cleaner in cabin.In the upper end portion of breather line, waterproof headkerchief is installed simultaneously, prevents rainwater from entering cabin from breather line.Also exhaust pump is housed in general cabin, regular is exhausted air in cabin.The subject matter that existing venting tubing system exists is, when exhaust pump is exhausted, ambient air directly enters cabin from breather line, make ambient air by breather line directly and exhaust pump formed and reflux, reduce the overall exhaust effect of exhaust pump to cabin.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, stops ambient air to enter cabin by breather line, improve the cabin outlet valve of exhaust effect when providing a kind of exhaust pump to work.
The technical solution of the utility model comprises valve body, valve body is shaped with the inlet passage be connected with cabin breather line, is shaped with the outlet passage be communicated with inlet passage, between inlet passage and outlet passage, arranges valve seat at the sidewall of valve body; Mainly inlet passage is communicated with valve seat upper-end surface by annular valve pocket, and be shaped with cylindrical valve pocket between outlet passage and valve seat lower end surface, annular valve pocket is shaping around the external cylindrical surface integrally casting of cylindrical valve pocket; Be shaped with concave spherical surface in the bottom surface of cylindrical valve pocket, the centre of sphere of this concave spherical surface, on valve seat center line, places ball float in concave spherical surface, and ball float adopts stainless steel hollow spheres; Valve seat lower end surface is shaped with the sealing surface cooperatively interacted with ball float; Valve body directly over valve seat is shaped with the ball float mount inlet concentric with valve seat, a capping is installed in this ball float mount inlet upper-end surface.
Preferably, at the port of outlet passage, dust-proof cover is installed.
The utility model has the advantages that in the valve pocket between valve seat outlet and outlet passage and ball float is set, when exhaust pump is exhausted cabin, ball float sucts and coordinates with valve base sealing by valve body inlet passage generation negative pressure, prevention air enters cabin from outlet valve and exhaust pump goes out interruption-forming convection channel, exhaust pump is made effectively to be discharged into outside cabin by the dirty gas in whole cabin, its good exhaust effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Cabin outlet valve as shown in Figure 1, comprise valve body 1, valve body 1 is shaped with the inlet passage 2 be connected with cabin breather line, the port of this inlet passage 2 is connected with cabin breather line by flange, the outlet passage 9 be communicated with inlet passage 2 is shaped with at the sidewall of valve body 1, between inlet passage 2 and outlet passage 9, arrange valve seat 6, under normal conditions, in cabin, gas forms convection channel by the inlet passage 2 of valve body 1, outlet passage 9 with cabin outer air; Inlet passage 2 is communicated with valve seat 6 upper-end surface by annular valve pocket 3, cylindrical valve pocket 5 is shaped with between outlet passage 9 and valve seat 6 lower end surface, annular valve pocket 3 is shaping around the external cylindrical surface integrally casting of cylindrical valve pocket 5, namely valve body 1 and inlet passage 2, outlet passage 9, annular valve pocket 3, cylindrical valve pocket 5 adopt integrally casting shaping, and annular valve pocket 3 is arranged around the external cylindrical surface of cylindrical valve pocket 5; Be shaped with concave spherical surface in the bottom surface of cylindrical valve pocket 5, the centre of sphere of this concave spherical surface is on valve seat 6 center line, and in concave spherical surface, place ball float 4, ball float 4 adopts stainless steel hollow spheres; Valve seat 6 lower end surface is shaped with the sealing surface cooperatively interacted with ball float 4, when exhaust pump is vented cabin, stops ambient air to enter cabin by outlet valve, improves exhaust pump to the exhaust effect of cabin entirety; Valve body 1 directly over valve seat 6 is shaped with the ball float mount inlet 7 concentric with valve seat 6, a capping 8 is installed in this ball float mount inlet 7 upper-end surface, the diameter of ball float mount inlet 7 is greater than the external diameter of ball float 4 and valve seat 6, and valve seat 6 and ball float 4 can be installed from this ball float mount inlet 7.
At the port of outlet passage 9, dust-proof cover 10 is installed, prevents dust from entering in cabin from outlet valve.
