Description
Technical field
A kind of valve mechanism cover is the utility model is related to, more particularly, to a kind of cylinder with stronger oil gas separation
Housing.
Background technology
At present, installation Oil-gas Separation respirator is both needed in the valve mechanism cover of diesel engine to carry out the gas for discharging diesel engine
Hydrocarbon filter, one purifies discharge gas, prevents it from causing harmful effect to environment；Two control the machine oil of discharge, prevent machine
The transition of oil expends；Conventional structure is a kind of as disclosed in Chinese patent application CN201710202826.X, and " single-cylinder vertical is air-cooled
Diesel engine spiracle room bilayer Oil-gas Separation aeration structure ", it only installs respirator on the inside of valve mechanism cover, then passes through pipe
Pass is led and is discharged outside it, finds in actual use, and said structure oil gas separation is bad, has much room for improvement.
The content of the invention
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided valve mechanism cover of good oil gas separation effect.
What the purpose of this utility model was realized in：
A kind of valve mechanism cover, the valve mechanism cover include case, installation counterbore are provided with the madial wall of the case,
Respirator is installed, the bottom of the installation counterbore is provided with connecting hole, is set in the shell wall of the case in the installation counterbore
Passage one and passage two are equipped with, hole is connected the passage with installation counterbore once connected, one end of the passage two and passage
One is connected, on the madial wall for opening up case of the other end；The drainage of a bending is provided with the madial wall of the case
Groove, which is connected with installation counterbore, and has a cover board to be pressed together on installation counterbore and drainage trough.
A kind of valve mechanism cover of the utility model, partition plate is provided with the inner wall of the drainage trough and forms labyrinth seal structure.
After a kind of valve mechanism cover of the utility model, the passage one and the difference machine-shaping of passage two connect, by passage one
Openend closure on.
Compared with prior art, the beneficial effects of the utility model are：
The utility model imports the gas of discharge by drainage trough mode, and partition plate structure is then set in drainage trough
Into labyrinth seal structure, so that oil gas has carried out preliminary separation before respirator is entered, and reduce into breathing
The speed of device interior air-flow so that the follow-up gas into respirator can obtain more efficiently Oil-gas Separation, ensure discharge
Gas is purified by thoroughly oil gas, is realized to the pollution-free of environment.
Brief description of the drawings
Fig. 1 is a kind of structure diagram removed after cover board of valve mechanism cover of the utility model.
Fig. 2 is a kind of A-A sectional views of valve mechanism cover of the utility model.
Wherein：
Case 1, installation counterbore 2, connecting hole 3, passage 1, passage 25, drainage trough 6, partition plate 7.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of valve mechanism cover that the utility model is related to, the valve mechanism cover includes case 1, institute
State and installation counterbore 2 is provided with the madial wall of case 1, respirator is installed in the installation counterbore 2, the installation counterbore 2
Bottom is provided with connecting hole 3, passage 1 and passage 25 is provided with the shell wall of the case 1, the passage 1 is through connecting hole
3 are connected with installation counterbore 2, and one end of the passage 25 is connected with passage 1, and the other end opens up the interior of case 1
On side wall；The drainage trough 6 of a bending is provided with the madial wall of the case 1, which is connected with installation counterbore 2, and
There is a cover board to be pressed together on installation counterbore 2 and drainage trough 6；In use, after exhaust gas carries out preliminary Oil-gas Separation via drainage trough 6,
Secondary oil gas separation is carried out into the respirator in installation counterbore 2, then the gas after isolation of purified is via connecting hole 3, passage
1 and passage 25 export to outside；
Further, partition plate 7 is provided with the inner wall of the drainage trough 6 and forms labyrinth seal structure, so as to further carry
High oil gas separation；
Further, during processing, after passage 1 is connected with the difference machine-shaping of passage 25, by the opening end seal of passage 1
Block, be easy to be processed valve mechanism cover using this mode；
In addition：It should be noted that above-mentioned embodiment is only a prioritization scheme of this patent, the skill of this area
Any change or improvement that art personnel are done according to above-mentioned design, within the protection domain of this patent..
