Abstract
The utility model relates to a thermo valve of a screw compressor, comprising a housing. An oil filter joint is provided over the housing; the oil filter joint is connected with a lubricating oil filtering seat; the front end surface of the housing is provided with an oil filtering outlet; a first cold oil inlet is provided below the oil filtering outlet; the first cold oil inlet is communicated with one side of a valve core, and the other side of the valve core is provided with a hot oil outlet; the valve core is connected with a return spring; a second cold oil inlet is provided over the return spring; the bottom of the bottom valve core is connected with a valve cover; the valve cover is provided with a temperature control element; and the temperature control element is positioned in the valve core. According to the thermo valve of the screw compressor, the discharge capacity of a used air compressor is from 10 to 40 m<3>/min, and the largest usage pressure is 1.6 Mpa. The thermo valve of the screw compressor can completely replace a temperature control valve and an oil filter which are separated arranged, the temperature control valve is smartly integrated with a lubricating oil filter, a leakage point and pipelines are minimized, the market demand is satisfied, the thermo valve of the screw compressor is more energy-saving, reliability is high, maintenance is convenient, the service life is longer, etc.
Description
Technical field
The utility model relates to the parts that use on the air compressor in the mechanical technique, specifically a kind of helical-lobe compressor thermo valve.
Background technique
Screw-rod air compressor is little with its volume, noise is low, rate of fault is low, vibrate little, advantage such as power consumption is little; After getting into Chinese market, adopt rapidly for users, than higher, main frame on the air compressor and various valve member all depend on import in the air compressor technology content of this type; Domestic correspondent is essential these parts of import when the assembling screw-rod air compressor, not only will accept expensive price during these products of import, also will accept very long delivery date; And after sales service does not catch up with yet; Offshore company is relied in technical leading advantage, and the sale price of domestic enterprise can be described as sky-high price, has therefore had a strong impact on the development of domestic enterprise.
The oil-way system more complicated of general screw rod air engine, each bar oil pipe is crisscross, and is not attractive in appearance, and oil circuit leakage problem, befouling environment also often take place.The integrated design advantage of the screw air compressor thermo valve of project exploitation is to have reduced oil circuit, has reduced leakage point, and makes easier for installationly, in products perfection, has practiced thrift cost again, can be described as and kills two birds with one stone.
Summary of the invention
The purpose of the utility model is in order to overcome above deficiency, and the utility model provides a kind of volume a kind of helical-lobe compressor thermo valve little, simple in structure.
The purpose of the utility model realizes through following technological scheme: a kind of helical-lobe compressor thermo valve, comprise housing, and said housing top is provided with oil filter joint; Said oil filter joint is connected with the lubrication oil filtration seat, and the front-end face of said housing has oily filtering outlet, and said oily filtering outlet below is provided with first cold oil inlet; Said first cold oil inlet communicates with spool one side, and the opposite side of said spool is provided with hot oil outlet, is connected with Returnning spring on the said spool; Said Returnning spring top is provided with second cold oil inlet; The bottom of said spool is connected with valve gap, and said valve gap is provided with temperature control element, and said temperature control element is positioned at said valve core inside.Said helical-lobe compressor thermo valve uses the air displacement of air compressor to be 10-40m
3/ min, maximum working pressure are 1.6Mpa.
The utility model compared with prior art has the following advantages:
The screw air compressor thermo valve can replace heat-operated valve and the oil strainer that was installed separately originally fully.Integrate heat-operated valve and lubricating oil filter dexterously, reduce leak point and pipeline, also complied with the market demand, more energy-conservation, reliability is high, and easy to maintenance, the life-span is longer.

Label among
figure: 1-housing, 2-oil filter joint, 3-lubrication oil filtration seat, 4-oil filtering outlet, 5-first cold oil inlet, 6-spool, 7-Returnning spring, 8-second cold oil inlet, 9-valve gap, 10-valve gap, 11-temperature control element.
Embodiment:
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of helical-lobe compressor thermo valve like Fig. 1, comprise housing 1, said housing 1 top is provided with oil filter joint 2; Said oil filter joint 2 is connected with lubrication oil filtration seat 3, and the front-end face of said housing 1 has oily filtering outlet 4, and said oily filtering outlet 4 belows are provided with first cold oil inlet 5; Said first cold oil inlet 5 communicates with spool 6 one sides, and the opposite side of said spool 6 is provided with hot oil outlet 7, is connected with Returnning spring 8 on the said spool 6; Said Returnning spring 8 tops are provided with second cold oil inlet 9; The bottom of said spool 6 is connected with valve gap 10, and said valve gap 10 is provided with temperature control element 11, and 11 in said temperature control unit is positioned at said spool 6 inside.Said helical-lobe compressor thermo valve uses the air displacement of air compressor to be 10-40m
3/ min, maximum working pressure are 1.6Mpa.
The utility model compared with prior art has the following advantages:
The screw air compressor thermo valve can replace heat-operated valve and the oil strainer that was installed separately originally fully.Integrate heat-operated valve and lubricating oil filter dexterously, reduce leak point and pipeline, also complied with the market demand, more energy-conservation, reliability is high, and easy to maintenance, the life-span is longer.
It is 10-40m that the screw air compressor thermo valve is suitable for air displacement
3The screw air compressor of/min, it is temperature required that it can stably keep in the system oil circulation, can solve oily filtration problem effectively again.Integrate heat-operated valve and lubricating oil filter dexterously, reduced oil circuit, reduced leakage point.
