Abstract
The utility model relates to a combination valve used for controlling screw rod compressor, belonging to the technical field of control device. The valve is internally provided with a valve core which is positioned by a positioning ring; a membrane is arranged between the valve cover and the valve. An adapter is connected with a slippery valve core which is arranged in the valve; besides, the valve is fixed on the electromagnetic valve, and a plug is connected with the valve. The utility model has the advantages of a few connection pipelines, compact and simple structure and a few system exposure points as well as further improving the reliability of the system and having low machining cost of the components and small system volume.
Description
The utility model relates to a kind of helical-lobe compressor control and uses combination brake switch and proporting, belongs to the control gear technical field.
Before the utility model was made, in prior art, the original control system of helical-lobe compressor was to adopt pressure valve, compositions such as guiding valve, atmospheric valve, normally open solenoid valve, normally closed solenoid valve.Above-mentioned several valve couples together them by certain way by pipeline; The action of control easing valve and system's unloading venting and shutdown venting.This kind structure ways of connecting causes connecting pipeline many, and line arrangement is mixed and disorderly; System leak point is many, increases the fault point, reduces the reliability of system; Components and parts processing cost height, system bulk is big.
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple in structure, and the complete machine connecting pipeline is few, and system's leakage dew point is few, and the components and parts processing cost is low, and can improve the helical-lobe compressor control combination brake switch and proporting of system reliability.
Main solution of the present utility model is achieved in that it adopts spool 3 is housed in valve body 1, by positioning ring 2 location, between valve gap 4 and the valve body 1 diaphragm 5 is housed, connect sliding spool 7 on the joint 11 and be installed in the valve body 1, Motionless electromagnetic valve 10 on the valve body 1, plug screw 12 is connected on the valve body 1.
Description of drawings:
Fig. 1 is the utility model structural front view:
Fig. 2 is the utility model structure plan view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts spool 3 is installed in valve body 1, and by positioning ring 2 location, valve gap 4 is installed on the valve body 1, and is fixing by 6 four on bolt, and between valve gap 4 and valve body 1 diaphragm 5 is housed.Connect sliding spool 7 on the joint 11, adopt 8 sealings of O shape circle, and be installed in the side of valve body 1.Plug screw 12 is connected on the valve body 1.Solenoid valve 10 is installed on the valve body 1, and is fixing by four screws 9.
The utility model selects in the two-way gas pressure signal high a road automatically as action source of the gas signal, by the internal actions of an electromagnetic valve combination brake switch and proporting, thereby the emptying that reaches gas in the open and close of control easing valve and the deaerator with close.
Compared with the prior art the utility model has the following advantages: 1, complete machine connection pipeline is few, and structure is tight Gather, simply; 2, system's leakage dew point is few, can further improve the reliability of system; 3, components and parts processing Cost is low; 4, system bulk is little.
