Abstract
The utility model provides a temperature control valve of an air compressor. The temperature control valve of the air compressor is used for solving the problems that as an existing air compressor is large in number of leakage points and poor in sealing performance, lubricating oil of a system leaks and the service life of the air compressor is shortened. The temperature control valve of the air compressor comprises a valve body, a piston arranged in the valve body, a temperature control valve core arranged in the piston, a spring arranged outside the piston, a gland and a check ring, wherein a first O-shaped ring set is arranged between the valve body and the gland. The temperature control valve of the air compressor is simple in structure and reasonable in arrangement. By the adoption of the temperature control valve, the distance between an oil inlet and an oil outlet of a main engine housing of the air compressor can be shortened to be 10-100mm, the sealing performance is good, and the service life is long.
Description
Technical field
The utility model relates to the parts that use on the air compressor in mechanical technique, refers to especially air compressor thermostat valve.
Background technique
Air compressor is the main body in source of the gas work, and it can be converted into the mechanical energy of prime mover (normally motor) device of gas pressure energy, is compressed-air actuated pressure generator, very extensive with the application in producing in daily life.Thermostat valve, as the vitals of air compressor, can ensure that lubricant oil leads to radiator under high-temperature condition cooling, closes lubricant oil simultaneously and lead to cooler under low temperature condition, avoids the too low the optimum state that do not reach of machine temperature.Existing high performance thermostat valve is mostly by import; cost is high, the delivery cycle is long; and domestic thermostat valve sealing is poor, leakage point is many, temperature control reaction velocity is slow; the shutdown of often breaking down; cause internal system emulsification of lubricant to go bad or pyrometamorphism; aggravation has corrosion and the wearing and tearing of relative movement part, makes air compressor main machine impaired, has shortened the working life of air compressor.
Model utility content
The utility model proposes a kind of air compressor thermostat valve, for solving, existing air compressor thermostat valve leakage point is many, sealing is poor, causes the easy emulsion deterioration of internal system lubricant oil, affects the compressor problem in working life.
The technical solution of the utility model is achieved in that
An air compressor thermostat valve, comprising: valve body, be arranged on the piston in valve body, and be arranged on the temperature controlled valve core in piston, be arranged on the spring outside piston, gland and back-up ring;
Between valve body and gland, be provided with an O type circle group.
Preferably, adopt after above-mentioned air compressor thermostat valve, the filler opening on air compressor host shell and the spacing of oil outlet are 10-100mm.
Preferably, an O type circle group comprises at least 3 O type circles that diameter is different.
Preferably, also comprise the 2nd O type circle group.
Preferably, the 2nd O type circle group comprises at least 2 O type circles that diameter is different.
The air compressor thermostat valve the utility model proposes, by between valve body and air compressor host shell, arranges respectively the 2nd O type circle group and an O type circle group between spring and gland, improved the whole sealing of air compressor thermostat valve, has reduced leakage point; Filler opening on shortening thermostat valve and the spacing of oil outlet, reduced harmful effect thermostat valve being caused owing to expanding with heat and contract with cold, and effectively avoided the phenomenons such as leakage of oil, emulsification of lubricant.This air compressor thermostat valve is simple in structure, arrange rationally, good airproof performance, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the constituent elements schematic diagram of the utility model air compressor thermostat valve;
Fig. 2 is the mounting point schematic diagram of this air compressor thermostat valve in air compressor;
Fig. 3 is for adopting the left view of the air compressor of this thermostat valve.
In figure:
1, valve body; 2, temperature controlled valve core; 3, piston; 4, spring; 5, an O type circle group; 6, gland; 7, back-up ring; 8, the 2nd O type circle group; 9, filler opening; 10, oil outlet.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1-Fig. 3 is common: a kind of air compressor thermostat valve, comprising: valve body 1, be arranged on the piston 3 in valve body 1, be arranged on the temperature controlled valve core 2 in piston 3, be arranged on the spring 4 outside piston 3, gland 6 and back-up ring 7; Between valve body 1 and gland 6, be provided with an O type circle group 5.
Mostly by import, there is the inconveniences such as cost is high, procurement cycle is long in existing air compressor thermostat valve, state-owned air compressor thermostat valve leakage of oil point is many, sealing is poor, easily makes when in use emulsification of lubricant and then causes air compressor shortening in working life.The air compressor thermostat valve the utility model proposes, system leakage of oil point is few, good airproof performance.
As shown in Figure 3: adopt after described air compressor thermostat valve, the filler opening 9 on air compressor host shell is 10-100mm with the spacing of oil outlet 10.
Adopt after existing thermostat valve, the filler opening 9 on air compressor host shell is far away with oil outlet 10 spacing, and the impact of being expanded with heat and contract with cold is large; After the thermostat valve that employing the utility model proposes, shorten the spacing of filler opening on air compressor host shell 9 and oil outlet 10, existing spacing 130mm effect can be adjusted into 10-100mm, reduced the impact of expanding with heat and contract with cold on thermostat valve.
An embodiment more of the present utility model, as a kind of preferred technological scheme, an O type circle group 5 at least comprises 3 O type circles that diameter is different.
Another embodiment of the present utility model, as a kind of preferred technological scheme, also comprises the 2nd O type circle group 8.
Another embodiment of the present utility model, as a kind of preferred technological scheme, the 2nd O type circle group 8 comprises at least 2 O type circles that diameter is different.
Existing thermostat valve, when valve body 1 is connected with air compressor host shell, is only provided with 1 O type circle conventionally, and the compressor operation time is when longer, and the O type circle between valve body 1 and air compressor host shell may become flexible, aging, and then forms leakage point.The air compressor thermostat valve the utility model proposes, between valve body 1 and air compressor host shell, be provided with the 2nd O type circle group 8, the 2nd O type circle group 8 comprises at least 2 O type circles that diameter is different, and sealing effect is better, has solved the leakage problem that air compressor long-time running causes.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
