Description
[technical field]
The utility model relates to the technical field of auto parts machinery, particularly a kind of technical field of Pcv valve.
[background technique]
Pcv valve is one of component important in the crankcase ventilation system of motor, plays an important role to adjustment crankcase pressure.Gas in crankcase is imported intake manifold by Pcv valve by Pcv valve, and has a small amount of air directly to enter intake manifold by air-strainer through Pcv valve, and Pcv valve effectively prevent the phenomenons such as closure place freezes, insufficient, the deterioration of emission of burning.Also prevent gas blowby from entering air, prevent machine oil from going bad simultaneously.In prior art, plunger type Pcv valve is applied, and it is used in ventilation system for automobile crankcase.Automobile is in operation, and the gas blowby of generation can flow into crankcase, and crankcase gas blowby flows to intake manifold by Pcv valve and connecting tube, then arrives firing chamber and again burns.Pcv valve plays by controlling the derived quantity of gas blowby the effect controlling crankcase pressure, but traditional Pcv valve due to valve head be tack or circular arc head, often reverse sealability is poor, can cause backflow.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of novel Pcv valve, and structure is simple, connects closely, the reverse good seal performance of valve, long service life.
For achieving the above object, the utility model proposes a kind of novel Pcv valve, comprise valve body, valve seat and valve gap, described valve seat and valve gap are integral type structure, and valve inner is inserted in one end of described valve gap, by being welded to connect between valve body and valve gap, described valve inner is provided with gas-entered passageway, and described valve gap inside is provided with outlet passageway, and described valve body and valve gap joint are provided with valve, described gas-entered passageway is connected by valve with between outlet passageway, and on described valve outer wall, cover has return spring.
As preferably, described valve comprises first, second, the 3rd and the 4th, and the shape of described first is the rectangle of band chamfering, described second in taper.
As preferably, the outer wall of described 3rd is provided with back-up ring, the section area that the section area of described 4th is greater than the 3rd.
As preferably, the outer wall of described valve gap is provided with retaining ring, and described retaining ring and valve gap are formed in one.
As preferably, the inlet of described gas-entered passageway is provided with chamfering.
The beneficial effects of the utility model: the utility model is by being set to integral structure by valve seat and valve gap, by being welded to connect between valve body and valve gap, install simple and convenient, connect closely, ensure that sealing, add working life, reduce production cost, by valve being arranged to integrated four parts, first has adopted the rectangle being with chamfering simultaneously, second in taper, 3rd is provided with back-up ring, the section area that the 4th section area is greater than the 3rd, and structure is simple, stability is strong, adds the sealability that Pcv valve is reverse simultaneously.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
