Description
Technical field
The utility model is related to the list on check valve field, more particularly to the cooling system such as automobile-used, engineering machinery use, peculiar to vessel
To valve, specifically a kind of check valve in cooling system.
Background technology
Check valve on the cooling system such as automobile-used, engineering machinery use, peculiar to vessel, as shown in Figure 1.Open up on the pedestal 1 of cylinder body
There is oil line pipe 3, check valve 2 is arranged in the oil line pipe 3.With reference to Fig. 3, conventional check valve 2 is generally integral valve, bag
Include valve body 5, valve gap 7, spring 8 and sealing ring 6.Described spring 8 is sleeved on described valve body 5, and spacing in the bottom of valve body 5
And valve gap 7 between.Sealing ring 6 is arranged on the top of valve body 5, and in not oil-feed, the passage between closed valve 5 and valve gap 7 makes
Machine oil inside cooling system will not flow back away and prevent valve body 5 from coming off.Check valve 2 is by valve gap 7 and the mistake of oil line pipe 3
It is full of to coordinate and is fixed on pedestal 1 with the limited step 4 on asphalt channel 3.When the oil line pipe of the machine oil from pedestal 1 of engine
3 when flowing to check valve, and in the presence of oil pressure, valve body 5 overcomes the tension force of spring 8 to move to the bottom direction of valve body 5, valve gap 7 with
Asphalt channel between valve body 5 is opened, and other coolant flats are flowed out in the radial passage that machine oil is opened up from valve body 5
In.The check valve of this structure, is at least made up of the part of more than three, and structure is complex, and manufacturing cost is also higher.
The content of the invention
To be solved in the utility model is the above-mentioned technical problem that prior art is present, it is desirable to provide a kind of simple structure,
Cheap cooling system check valve.
To solve the above problems, the utility model is employed the following technical solutions：A kind of check valve in cooling system,
Including valve gap and valve body, it is characterised in that offer oil duct and a centre bore with bulge loop on described valve gap；Described valve
Body is made up of elastomeric material, in bowl structure, and is provided with newel, and described newel is provided with groove；Described bulge loop and
Groove is axially and radially while interference fit.
A kind of check valve in cooling system of the present utility model, valve gap and valve body are by bulge loop and groove radially
It is full of cooperation, makes valve gap and valve body reliably fixed；Bulge loop and groove are in axial interference fit so that in stopped status lower valve body
Bowl-shape periphery props up valve gap, and oil duct is closed, and prevents machine oil from flowing back.Under open state, in-engine machine oil flows to check valve,
Because valve body is made using elastomeric material, and in bowl structure, under oil pressure effect, rout up downwards, oil duct is opened, machine oil from
Oil duct on valve gap is flowed into, and Jing valve bodies outside flows to other coolant flats.When engine is returned to stopped status, valve body resilience
To original state, so as to prop up valve gap, oil duct is closed, machine oil would not be back in oil sump.
A kind of check valve in cooling system of the present utility model, by elastic valve body deformation can be recovered, and make valve body
With valve gap in closing and opening two states, so as to realize one-way conduction.Because the utility model is only with valve gap and valve body
Two parts, structure is very simple, and easy to manufacture is greatly reduced and manufactured assembly cost, with good economic benefit and
Wide market prospects.
According to the utility model, multiple oil ducts are offered on described valve gap, between adjacent oil duct reinforcement is provided with.
According to the utility model, interference fit between described valve gap and the oil line pipe of pedestal.
According to the utility model, described valve body is made using elastomeric material, preferred silica gel, hydrogenated nitrile-butadiene rubber or ethene
ACM.

Specific embodiment
See figures.1.and.2, the check valve of prior art, its defect is already discussed above, will not be described here.
With reference to Fig. 3 and Fig. 4, a kind of check valve in cooling system of the present utility model, including valve gap 11 and valve body
12。
Oil duct 17 and a centre bore 18 with bulge loop 14 are offered on valve gap 11 with reference to described in Fig. 5 and Fig. 6.In this reality
In applying mode, described oil duct 17 is 3, and reinforcement 16 is provided between adjacent oil duct 17.
With reference to Fig. 7 and Fig. 8, described valve body 12 is made using elastomeric material, such as silica gel, hydrogenated nitrile-butadiene rubber or ethylene propylene
Olefin(e) acid ester rubber.The elastic performance of silica gel is best, but expensive.Hydrogenated nitrile-butadiene rubber and ethylene-acrylate rubber price
It is slightly cheap.
Described valve body 12 is in bowl structure.Using elastomeric material and specific bowl structure so that valve body 12 has appropriateness
Rigidity and elasticity, that is, ensure that valve body and valve gap are closed in stopped status, while also ensuring that valve body can in open state
Washed open by machine oil and open oil circuit after upset.Newel 13 is provided with the middle part of valve body 12, is provided with recessed on described newel 13
Groove 15.Described bulge loop 14 and groove 15 are full of cooperations in radial direction, make valve gap and the reliable fixation of valve body；Bulge loop 14 and groove 15 are in axle
To interference fit, in stopped status lower valve body 12 valve gap 11 is propped up.
Interference fit is also adopted by between described valve gap 11 and the oil line pipe 3 of pedestal, the structure of such valve gap 11 is the most
Simply, and other parts need not be increased.
With reference to Fig. 9 and Figure 10, when using, check valve of the present utility model is arranged on into the oil circuit of engine cylinder susceptor body 1
In pipeline 3, the inwall interference fit of the oil line pipe 3 of valve gap 11 and pedestal makes valve gap 11 just be embedded in oil line pipe 3
On limited step 4.Under stopped status, valve body 12 props up valve gap 11, and oil duct is closed, and can prevent machine oil from flowing back.
With reference to Figure 11, under open state, in-engine machine oil flows to check valve, because valve body 12 adopts elastomeric material
Make, and in bowl structure, under oil pressure effect, rout up downwards, oil duct is opened, and oil duct 17 of the machine oil from valve gap 11 flows
Enter, the outside of Jing valve bodies 12 flows to other coolant flats.
When engine is returned to stopped status, valve body 12 recoils to original state, so as to prop up valve gap 11, closes oil
Road, machine oil would not be back in oil sump.
Knowable to being analyzed above, traditional check valve, at least by 3 part composition described above, price more than 6 yuan, cost
It is higher.A kind of check valve in cooling system of the present utility model, compared with conventional art, only with valve gap and valve body two
Individual part, structure is very simple, easy to manufacture, greatly reduces and has manufactured assembly cost, and price is about at 2 yuan or so, thus tool
There is good economic benefit and wide market prospects.
It is to be understood that：Above-described embodiment is to explanation of the present utility model, rather than to of the present utility model
Limit, any utility model without departing from the utility model spirit is created, and each falls within protection of the present utility model
Within the scope of.
