Preferably, said plunger tube and valve body upper end is fixed for roll extrusion.
Preferably, said coil case is a stepped shape, and this coil case is a hollow structure, is placed in the plunger tube outside, and said coil block is fixed on the inwall of coil case through the skeleton cover.
Preferably, said valve body also is provided with mounting bracket, and said mounting bracket is positioned at the valve body middle part.
Preferably, hard sealing is equipped with at said valve port place.
Preferably, said back-up ring passes through riveted fixing in valve body lower end.
Implement the solenoid valve that is used for heavily blocking clutch of the utility model, have following beneficial effect: solenoid valve push rod recess diameter is less, has therefore alleviated the push rod quality, is convenient to improve the movement speed of push rod.The roll extrusion of plunger tube and valve body upper end is fixed, and has improved the waterproof and the anti-dust performance of solenoid valve; The convenient processing of the shape of coil case, and can effectively protect coil; Mounting bracket has made things convenient for the installation of solenoid valve; Hard sealing in the valve port, wear resistance and impact resistance are better; Back-up ring is fixed on the valve body through the riveted joint mode, has further improved the anti-seismic performance of solenoid valve.
Description of drawings
To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the utility model sectional structure chart.
Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer, below in conjunction with embodiment and accompanying drawing, to the utility model further explain.
As can be seen from Figure 1, the clutch that the solenoid valve of the utility model is used for heavily blocking, this solenoid valve comprises valve body 15; Have valve port 10 in the valve body 15, and valve port 10 lower ends (convenient for narration, be as the criterion with direction shown in scheming; But this direction does not limit the concrete structure of the utility model) sealing valve port spare 11 is housed, moving iron core 12 is equipped with in sealing valve port spare 11 lower ends, 12 3 of moving iron cores around; There is opening the lower end of moving iron core 12, and moving iron core spring 13 is equipped with in the inside, and back-up ring 14 is equipped with in moving iron core spring 13 lower ends; On valve body 15, can play shockproof effect through riveted fixing like this, this back-up ring 14 also can adopt other usual manners to fix certainly.Push rod 6 is equipped with in sealing valve port spare 11 upper ends, and push rod 6 comprises that bar portion 21 and diameter less than the neck 22 of bar portion, have center hole 23 on the sealing valve port spare 11, and the aperture of this center hole 23 is less than the diameter of push rod neck 22, so that push rod 6 is against on the sealing valve port spare 11.Valve body 15 upper ends are set with plunger tube 5; Movable core 4 is installed in the plunger tube 5, iron core spring 3 is housed in the movable core 4, iron core spring 3 is against the top of plunger tube 5; The bar portion 21 of push rod 6 is against on the movable core 4; This plunger tube 5 is fixed on the valve body through roll extrusion, so that sealing, can prevent dust, waterproof.Easy to connect for this solenoid valve is in use installed, the valve body 15 of solenoid valve is provided with mounting bracket 8.
