Abstract
The utility model discloses a kind of high-temp. resistant air compressor one-way valve, it includes and forms the valve seat and valve gap that center hole supplied gas passes through, described valve gap is set in valve seat upper end, black box is provided with in described valve base center hole, described black box includes the sealed pipe be fixed in valve base center hole, described sealed pipe inner bottom part forms the sealed mouth of truncated cone shape, the ball sealer that described sealed mouth upper end is provided with, described valve seat upper end outer circumferential face is fixed with elastic sealing ring with valve gap phase suit place, top, described valve seat upper end has annular slot, annular boss is formed with corresponding section, annular slot position in described bonnet central bore, described annular boss inlay card is in annular slot.The utility model arranges sealed pipe, sealed mouth and ball sealer in valve seat, can wash away for a long time through high-temperature gas, ensure sealability, adopt between valve seat and valve gap elastic sealing ring, annular slot and annular boss from embedded sealing configuration, structure is simple, and sealability is reliable.
Description
technical field:
The utility model relates to air compressor technical field, particularly a kind of high-temp. resistant air compressor one-way valve.
background technique:
At present, mostly the various air compressor one-way valve structures that market uses are to use dependence spring and valve block, and during air-breathing, inlet valve spring shrinks valve block and opens, and gas outlet valve spring stretches valve block is closed; During exhaust, inlet valve spring stretches, and valve block is closed, gas outlet valve spring contraction, the mode that valve block is opened, and this structure vapour lock is large, and it is large that sealing surface is subject to impact force, and in the case of a high temperature after Long-Time Service, valve block damages very fast, and tightness reduces, and economic benefit is lower.
model utility content:
The utility model provides a kind of high-temp. resistant air compressor one-way valve, and solve vapour lock in prior art large, it is large that sealing surface is subject to impact force, and valve block damages fast, and tightness is low, the problem that economic benefit is low.
Technology solution of the present utility model is as follows: a kind of high-temp. resistant air compressor one-way valve, it includes and forms the valve seat and valve gap that center hole supplied gas passes through, described valve gap is set in valve seat upper end, black box is provided with in described valve base center hole, described black box includes the sealed pipe be fixed in valve base center hole, described sealed pipe inner bottom part forms the sealed mouth of truncated cone shape, the ball sealer that described sealed mouth upper end is provided with, described valve seat upper end outer circumferential face is fixed with elastic sealing ring with valve gap phase suit place, top, described valve seat upper end has annular slot, annular boss is formed with corresponding section, annular slot position in described bonnet central bore, described annular boss inlay card is in annular slot.
Further, described valve seat and valve gap all adopt aluminium diecasting, and described ball sealer adopts teflon ball.
Further, described annular slot inner bottom part is embedded with seal washer.
Further, described ball sealer diameter is greater than sealed mouth upper-end inner diameter, is less than sealed pipe internal diameter.
Further, inner peripheral surface place, described sealed mouth upper end is the inverted cone-shaped structure matched with ball sealer.
The beneficial effects of the utility model are: in valve seat, arrange sealed pipe, sealed mouth is established in sealed pipe, ball sealer is resisted against sealed mouth upper end, can wash away for a long time through high-temperature gas, ensure sealability, between valve seat and valve gap, elastic sealing ring is set, and in annular slot inlay card annular boss from embedded sealing configuration realize sealing, structure is simple, and sealability is reliable.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 be in Fig. 1 B-B to sectional view;
Fig. 3 is the enlarged view that Fig. 2 centre circle shows A.
In figure: 1, valve seat; 2, valve gap; 3, sealed pipe; 4, sealed mouth; 5, ball sealer; 6, elastic sealing ring; 7, annular slot; 8, annular boss.
embodiment:
1-3 is to a kind of high-temp. resistant air compressor of the utility model one-way valve by reference to the accompanying drawings, is described further.
A kind of high-temp. resistant air compressor one-way valve of the present utility model, it includes and forms the valve seat 1 and valve gap 2 that center hole supplied gas passes through, valve gap 2 is set in valve seat 1 upper end, black box is provided with in valve seat 1 center hole, black box includes the sealed pipe 3 be fixed in valve seat 1 center hole, sealed pipe 3 inner bottom part forms the sealed mouth 4 of truncated cone shape, the ball sealer 5 that sealed mouth 4 upper end is provided with, valve seat 1 upper end outer circumferential face is fixed with elastic sealing ring 6 with valve gap 2 phase suit place, top, valve seat 1 upper end has annular slot 7, annular boss 8 is formed with corresponding section, annular slot 7 position in valve gap 2 center hole, annular boss 8 inlay card is in annular slot 7.
Valve seat 1 and valve gap 2 all adopt aluminium diecasting, and ball sealer 5 adopts teflon ball.Practicality with low cost, vapour lock is little, can at high temperature Long-Time Service.
Annular slot 7 inner bottom part is embedded with seal washer.It is reliable that guarantee annular boss 8 and annular slot 7 inlay rear sealing.
Ball sealer 5 diameter is greater than sealed mouth 4 upper-end inner diameter, is less than sealed pipe 3 internal diameter.
Inner peripheral surface place, sealed mouth 4 upper end is the inverted cone-shaped structure matched with ball sealer 5.When ball sealer 5 is resisted against sealed mouth 4 upper end, realize sealing.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
