Abstract
The utility model relates to an integral oil drain valve, which comprises a valve casing and a spool. The valve casing comprises a valve sleeve and a valve seat connected onto the valve sleeve, and the spool arranged in the valve seat comprises an ejector rod, a push rod and a spring, wherein the ejector rod is used for plugging an oil drain hole, the push rod is used for pushing the ejector rod, the spring is used for pushing the ejector rod in a direction opposite to the direction of pushing the valve, the outer wall of the ejector rod is closely attached to the inner wall of the valve seat, and a portion of the ejector rod connected with the push rod is arranged in the valve seat. The integral oil drain valve has the advantages that by the aid of the integral spool, the valve is fine in coaxiality, excellent in working stability, small in assembling clearance and leakproof, and the reliability of a valve line is high.
Description
Technical field
The utility model relates to a kind of fuel outlet valve, particularly relates to a kind of all-in-one-piece fuel outlet valve.
Background technique
Referring to Fig. 1; Fig. 1 is a fuel outlet valve of the prior art, and the normally split type spool of fuel outlet valve of the prior art (alleged here split type spool is meant that the spool in being arranged on valve seat is split type) is though processing is simple; Pressurize is effective; But when match grinding, connect during shortcoming, remove installation during assembling again, coaxality is poor.
The model utility content
The purpose of the utility model is in order to solve the existing defective of fuel outlet valve in the existing technology, to provide a kind of coaxality good, good operating stability, and the fit up gap is little, anti-leak, and the fuel outlet valve of valve line good reliability solves the problems referred to above.
To achieve these goals, the technological scheme of the utility model is following:
A kind of integrated type fuel outlet valve comprises valve casing and spool, and said valve casing comprises valve pocket and is connected the valve seat on the valve pocket; Said spool is arranged in the valve seat; Spool comprises the push rod and the push rod that is used to promote push rod that is used to block fuel outlet, also comprises the spring that push rod is promoted to the opposite direction that promotes valve, and the outer wall of said push rod and the inwall of valve seat are close to; It is characterized in that the part that said push rod is connected with push rod is in valve pocket.
Above-mentioned a kind of integrated type fuel outlet valve is characterized in that, the outer wall contacting part of the inwall of said valve seat and push rod is provided with a circle seal ring.
The beneficial effect that the utlity model has: the integrated type spool coaxality that this product adopts is good, good operating stability, and the fit up gap is little, anti-leak, valve line good reliability.
Description of drawings
Fig. 1 is the structural representation of fuel outlet valve in the existing technology.
Fig. 2 is the schematic representation of the utility model.
Embodiment
For making structure characteristic of the utility model and the effect of being reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1; Fig. 1 is the structural representation of fuel outlet valve in the existing technology; The spool 200 of fuel outlet valve in the prior art comprises push rod 210 that is used to block fuel outlet 110 and the push rod 220 that is used to promote push rod 210, but since the attachment portion of push rod 220 and push rod 210 in valve seat 140, so they when combining coaxality poor; Thereby make and be easy to generate the gap between spool 200 and the valve casing 100; The valve line reliability reduces, and causes easily can between push rod 220 and valve pocket 150, infiltrating leakage of oil from the oil that filler opening 120 gets into, and the effect of fuel outlet 110 places pressurize simultaneously is bad.
Referring to Fig. 2; Fig. 2 is a kind of integrated type fuel outlet valve of the utility model, comprises valve casing 100 and spool 200, and valve casing 100 comprises valve pocket 150 and is connected the valve seat 140 on the valve pocket 150; Spool 200 is arranged in the valve seat 140; Spool 200 comprises the push rod 210 and the push rod 220 that is used to promote push rod 210 that is used to block filler opening 110, also comprises the spring 300 that push rod 210 is promoted to the opposite direction that promotes valve, and the inwall of the outer wall of push rod 210 and valve seat 140 is close to; The part that push rod 210 is connected with push rod 220 makes that the spool 200 in the valve seat 140 is integral structure in valve pocket 150.The outer wall contacting part of the inwall of valve seat 140 and push rod 210 is provided with a circle seal ring 130 simultaneously.
The integrated type spool coaxality that this product adopts is good, good operating stability, and the fit up gap is little, anti-leak, valve line good reliability.So just can make and all can seal, leakage of oil can not take place at oil outlet 110 from the oil of filler opening 120 entering.
In sum; Be merely the preferred embodiment of the utility model; Be not to be used for limiting the scope that the utility model is implemented; All equalizations of doing according to the described shape of the utility model claim scope, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the utility model.
Claims (2)
