Abstract

The present invention relates to goat technical field, more particularly to a kind of hydraulic point machine fuel tank breather valve, it is stifled including fuel tank, big steel ball, fuel tank blanking cover, small steel ball, O-ring seal, fuel tank blocks lid, the fuel tank is blocked with passage, it is tapered that the fuel tank blocks up internal cross section, the big steel ball be placed in the fuel tank it is stifled in, the fuel tank blanking cover be arranged on the fuel tank block lid in, the fuel tank is blocked and covers be connected stifled with the fuel tank, small steel ball via is carried on the fuel tank blanking cover bottom, the diameter with diameter greater than the small steel ball of the small steel ball via, the small steel ball is placed between the big steel ball and the fuel tank blanking cover, the O-ring seal is placed in the root of the fuel tank blanking cover.This vent valve structure is simple, install convenient, and when goat such as occurs larger inclination or is inverted in shipment, be pressed in small steel ball in O-ring seal by the small steel ball motion because Action of Gravity Field drives of big steel ball, and sealing prevents oil from leaking.

Description

Hydraulic point machine fuel tank breather valve
Technical field
The present invention relates to goat technical field, more particularly to a kind of hydraulic point machine fuel tank breather valve.
Background technology
At present, fuel tank need to install breather valve when goat runs, to prevent from forming negative pressure in fuel tank, beneficial to oil pump operation.In the prior art, in shipment such as there is larger inclination or inversion in goat, cause hydraulic oil to be revealed, oil pump cisco unity malfunction. Therefore a kind of breather valve is urgently developed, can admits air into fuel tank and be prevented from hydraulic oil when goat is inclined in normal condition and reveal.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and a kind of hydraulic point machine fuel tank breather valve is provided, the leakage of hydraulic oil can be prevented when goat is inclined, fuel tank can be in normal state admitted air into again.
The present invention to achieve the above object, using following technical scheme:A kind of hydraulic point machine fuel tank breather valve, it is characterised in that:It is stifled including fuel tank, big steel ball, fuel tank blanking cover, small steel ball, O-ring seal, fuel tank blocks lid, the fuel tank is blocked with passage, it is tapered that the fuel tank blocks up internal cross section, the big steel ball be placed in the fuel tank it is stifled in, the fuel tank blanking cover be arranged on the fuel tank block lid in, the fuel tank is blocked and covers be connected stifled with the fuel tank, small steel ball via is carried on the fuel tank blanking cover bottom, the diameter with diameter greater than the small steel ball of the small steel ball via, the small steel ball is placed between the big steel ball and the fuel tank blanking cover, the O-ring seal is placed in the root of the fuel tank blanking cover.
The front portion of the small steel ball via is provided with taper surface.
The fuel tank is stifled to be threadedly attached on fuel tank.
The diameter with diameter greater than the small steel ball via of the big steel ball.
The beneficial effects of the invention are as follows:This vent valve structure is simple, install convenient, and under the state of normal position, the passage that air can be blocked up by fuel tank enters fuel tank to goat (dotted line is air routing), it is to avoid the oil of fuel tank forms negative pressure during operation.When in shipment such as there is larger inclination or be inverted in goat, big steel ball Because Action of Gravity Field drives small steel ball motion, small steel ball is pressed in O-ring seal, sealing prevents oil from leaking.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
State diagram when Fig. 2 is upside-down mounting of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the invention in detail.As shown in Fig. 1 Fig. 2, a kind of hydraulic point machine fuel tank breather valve, including fuel tank stifled 1, big steel ball 2, fuel tank blanking cover 3, small steel ball 4, O-ring seal 5, fuel tank blocks lid 6, the fuel tank is blocked with passage 7, it is tapered that the fuel tank blocks up internal cross section, the big steel ball be placed in the fuel tank it is stifled in, the fuel tank blanking cover be arranged on the fuel tank block lid in, the fuel tank is blocked and covers be connected stifled with the fuel tank, small steel ball via 8 is carried on the fuel tank blanking cover bottom, the diameter with diameter greater than the small steel ball of the small steel ball via, the small steel ball is placed between the big steel ball and the fuel tank blanking cover, the O-ring seal is placed in the root of the fuel tank blanking cover.The front portion of the small steel ball via is provided with taper surface 9.The fuel tank is stifled to be threadedly attached on fuel tank.The diameter with diameter greater than the small steel ball via of the big steel ball.
As shown in figure 1, fuel tank stifled 1 is threadedly attached on fuel tank, under the state of normal position, air can enter fuel tank to goat by the hole of fuel tank stifled 1 (dotted line is air routing), it is to avoid the oil of fuel tank forms negative pressure during operation.
As shown in Fig. 2 when goat such as occurs larger inclination or is inverted in shipment, big steel ball 2 drives small steel ball 4 to move due to Action of Gravity Field, and small steel ball 4 is pressed in O-ring seal 5, and sealing prevents oil from leaking.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
