Abstract
The invention discloses a high-temperature-resistant air compressor one-way valve which comprises a valve seat and a valve deck. Center holes are formed in the valve seat and the valve deck and air passes through the center holes. The upper end of the valve seat is sleeved with the valve deck. A sealing assembly is arranged in the center hole of the valve seat and comprises a sealing pipe fixed into the center hole of the valve seat. A circular-truncated-cone-shaped sealing opening is formed in the bottom in the sealing pipe. A sealing ball is arranged at the upper end of the sealing opening. An elastic sealing ring is fixed to the portion, sleeved with the valve deck, on the outer circumferential face of the upper end of the valve seat. An annular clamping groove is formed in the top of the upper end of the valve seat. An annular boss is formed at the portion, corresponding to the annular clamping groove, in the center hole of the valve deck and embedded in the annular clamping groove. According to the high-temperature-resistant air compressor one-way valve, the sealing pipe, the sealing opening and the sealing ball are arranged in the valve seat, the valve can be scoured by high-temperature gas for a long time, and the sealing performance is guaranteed; a self-embedded sealing structure of the elastic sealing ring, the annular clamping groove and the annular boss is adopted between the valve seat and the valve deck, so that the structure is simple and sealing performance is reliable.
Description
technical field:
The present invention 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.
summary of the invention:
The invention provides a kind of high-temp. resistant air compressor one-way valve, 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 invention 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.
Beneficial effect of the present invention is: 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 structural representation of the present invention;
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 present invention 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 invention, 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 invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
