Description
Technical field
The utility model belongs to a kind of device of gas mass flow detection, and concrete is a kind of solenoid valve of gas mass flow amount controller.
Background technique
At present, the detection of the mass flow rate of gas, metering and control set for adjusting are used very wide aborning, on the market various mass flow controllers are arranged now, the accuracy of their purposes and detection has nothing in common with each other, one of them very important components be exactly solenoid valve.The performance of solenoid valve and the quality of quality have directly influenced the purposes of mass flow controller and the accuracy of detection.Current, the solenoid valve that is applicable to the mass flow controller of small-flow gas in the detection is few, and aspects such as the precision of control detection, repeatability, speed of response, reliability, range of working pressure and convenient degree of operation all have much room for improvement, therefore, need to propose a kind of flexibility and reliability more, the measuring accuracy height, the solenoid valve of the mass flow controller of small-flow gas in easy and simple to handle being fit to.
The model utility content
The purpose of this utility model is at the problems referred to above, proposes a kind of solenoid valve of improved mass flow controller, well addresses the above problem.
The purpose of this utility model realizes by following technical proposals:
A kind of solenoid valve of mass flow controller mainly comprises: valve component, mangetic core assembly, valve port, base, described valve component mainly are made of valve body, nut, valve bonnet, line bag, magnetic support; Described magnetic support is fixed on the base, described line bag is placed in the valve bonnet, by the nut on the valve body valve component is fixed on the base, described mangetic core assembly mainly by armature, connecting rod, end seat, spring sheet, sealing valve port seat, sealing valve port pad and constitute, the upper end of described connecting rod is fixedly connected in the intermediate hole of described armature lower end, the lower end of described connecting rod, and the thin cylinder by the centre passes spring sheet, fixedly connected then sealing valve port seat is equipped with the sealing valve port pad below the sealing valve port seat; Described valve port is fixedly mounted on the base, its improvement is, a magnet ring is installed in the middle of valve bonnet and the nut in the described valve component, on the spring sheet of the lower end of connecting rod described in the mangetic core assembly, be provided with spacer in addition, be provided with down spacer below the spring sheet, between spring sheet and base, be provided with packing ring.Between connecting rod and valve body, be provided with one and end seat.
The solenoid valve of a kind of mass flow controller of the present utility model, the joint between described valve body and base are provided with a seal ring, can reach the effect of better sealing.
The solenoid valve of a kind of mass flow controller of the present utility model, owing in valve component, in the middle of valve bonnet and the nut magnet ring is installed, thus strengthened the magnetic attraction effect; Owing to use comparatively elongated connecting rod that armature is connected with the sealing valve port seat, make that the switch of valve port is more flexible, between connecting rod and valve body, be provided with one and end seat, make elongated connecting rod be not easy, and lubricated; Spacer on spring sheet, increasing, the distance that can adjust between armature and the valve body top is the move distance of whole valve, accesses the specification of the various flows of control easily; Spacer under increasing below spring sheet can be adjusted the distance of sealing valve port pad and valve port, and is also very more flexible.A packing ring is set between spring sheet and base,, prevents the inclination of solenoid valve reliably by adjusting the chamfering of packing ring.Easy to adjust flexibly accommodation is wide so solenoid valve of the present utility model compared with prior art, has, and detects control accurately, and speed of response is fast, good stability, advantage such as easy and simple to handle.
