The model utility content
For above-mentioned deficiency of the prior art, the purpose of this utility model is that easy obstruction of atmospheric pressure balance tube that solves present hand-held gardens device fuel tank makes oil-feed have some setbacks, affect its normal use, and fuel oil provides a kind of atmospheric pressure balance tube of power plant fuel tank easily from deficiencies such as the atmospheric pressure balance tube spill.
The technical solution of the utility model is as follows: the atmospheric pressure balance tube of power plant fuel tank, comprise body, it is characterized in that, described body is comprised of suction tude, balanced body, sealing plug and sealing cover, the front end of balanced body is arranged in the endoporus of suction tude, the vent of balanced body is communicated with the endoporus of suction tude, and sealing plug is arranged in the inner chamber of balanced body, and vent is communicated with inner chamber; One section of the inner chamber of balanced body is conical surface, and taper fit between the sealing plug outer side surface; Pore is set on the sealing plug; Sealing cover is arranged on the sealing plug, sealing plug and balanced body are covered, on sealing cover or sealing plug be provided with gas via-hole; Gas via-hole on sealing cover or the sealing plug is connected with the endoporus of pore, inner chamber, vent and suction tude, forms the passage of gas.
Further feature is, on the outer surface of balanced body front end, is provided with some roads annular projection, is conical surface between the adjacent annular projection in twos.
On sealing cover, the part bending down is set, leave between the outer surface of part bending down and balanced body intermittently, and be provided with the projection that matches with the outer surface of balanced body on the part bending down.
At the gas via-hole that sealing cover arranges, be to leave intermittently between the contact position of sealing plug and sealing cover, this intermittently forms gas via-hole, in described gas via-hole is enclosed in by the part bending down.
With respect to prior art, the utlity model has following beneficial effect:
When 1, can the fuel oil in fuel tank swinging up and down, prevent that the atmospheric pressure balance tube of fuel from fuel tank from spilling; Guarantee safe handling.
2, the crisp bits of the atmospheric pressure balance tube of the fuel tank fritter plant that can not be cut stop up, and make the fuel tank inner chamber keep being in communication with the outside, and oil-feed is smooth and easy, makes the burning of engine chamber be in stable, reliable state.
3, the atmospheric pressure balance tube that prevents fuel from fuel tank spills, and saves fuel oil.
Description of drawings
Fig. 1 is the sectional view of the atmospheric pressure balance tube of the utility model power plant fuel tank.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the atmospheric pressure balance tube of power plant fuel tank of the present utility model, comprise body 1, described body 1 is comprised of suction tude 2, balanced body 3, sealing plug 4 and sealing cover 5, the front end of balanced body 3 is arranged in the endoporus of suction tude 2, namely inserts in the endoporus of suction tude 2 one ends, and the vent 6 of balanced body 3 is communicated with the endoporus of suction tude 2, sealing plug 4 is arranged in the inner chamber 7 of balanced body 3, and vent 6 is communicated with inner chamber 7; One section of the inner chamber 7 of balanced body 3 is conical surface, and taper fit between sealing plug 4 outer side surfaces; Pore 8 is set on the sealing plug 4, and pore 8 is connected with the endoporus of inner chamber 7, vent 6 and suction tude 2, forms the passage of gas.Sealing cover 5 is arranged on the sealing plug 4, inner chamber 7 with sealing plug 4 and balanced body 3(balanced body 3) covers, on sealing cover 5 or sealing plug 4 be provided with gas via-hole, be in communication with the outside, the gas of outside atmosphere enters in the sealing plug 4 by the gas via-hole on sealing cover 5 or the sealing plug 4, enter the inner chamber 7 of balanced body 3 by pore 8, enter the endoporus of suction tude 2 by vent 6; Suction tude 2 is arranged in the fuel tank in use, and the inner chamber that holds fuel oil with fuel tank is communicated with, and the endoporus by suction tude 2 passes into the inner chamber of fuel tank with the gas of ambient air, and its inner chamber is communicated with the gas of ambient air, and its pressure equates with atmospheric pressure.
