Technical Field

The utility model belongs to the solenoid valve field especially relates to a direct action type solenoid valve.

Background

Direct action type solenoid valve, during the circular telegram, solenoid produces the electromagnetic force and lifts the closure from the valve seat, the valve is opened, during the outage, the electromagnetic force disappears, the spring is pressed the closure on the valve seat, the valve is closed, when direct action type solenoid valve uses, it is fixed with the direct spiro union of pipeline usually, single connected mode, the leakproofness is relatively poor, easily lead to fluidic leakage in the use, the big particulate matter that contains in the fluid simultaneously enters into the valve along with the fluid, lead to the inside jam of valve easily, and then influence the normal use of valve, the result of use is relatively poor.

Disclosure of Invention

The utility model aims at providing a direct action type solenoid valve, it is relatively poor to solve current direct action type solenoid valve leakproofness, easily leads to the fluid to leak in the use, simultaneously, the big particulate matter that contains in the fluid leads to the inside jam of valve along with in the fluid enters into the valve easily, and then influences the normal use of valve, the relatively poor problem of result of use.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

a direct-acting electromagnetic valve comprises a valve body, a filter screen, a collecting barrel, a flange sleeve and an elastic snap ring, wherein a fixed plate is welded at the inlet of the valve body and is connected with the filter screen in a buckling manner, a flexible clamping block is welded on the filter screen, a clamping groove is formed in the fixed plate, the flexible clamping block is clamped in the clamping groove, a mounting frame is fixed on the outer portion of the valve body, the collecting barrel is communicated with the inner portion of the valve body, and the mounting frame is in threaded connection with the collecting barrel;

the flange sleeves are welded on the inlet and the outlet of the valve body and the connecting pipe, the flange sleeves are fixedly connected through bolts, the end of the connecting pipe is welded with an elastic snap ring, a clamping groove is formed in the flange sleeve connected with the valve body, and the elastic snap ring is clamped in the clamping groove.

The flexible clamping block is of an integrated structure and consists of a round rod and an arc-shaped flexible lug fixed at the top end of the round rod, and the bottom end of the round rod is welded on the side surface of the filter screen.

The cross-section of the elastic snap ring is isosceles trapezoid, and the cross-section of the clamping groove is concave isosceles trapezoid matched with the elastic snap ring.

Compared with the prior art, the beneficial effects of the utility model are that:

the direct-acting electromagnetic valve is reasonable in structure, fluid leakage is avoided by adopting a double-layer sealing structure, large particles can be discharged, and internal blockage of the valve is prevented. When being connected electromagnetic valve body and connecting pipe, both butt joint are in the same place, because of the elastic action of elasticity snap ring, final electromagnetic valve body passes through elasticity snap ring joint with the connecting pipe and seals together, then passes through fixing bolt spiro union with the flange cover and fixes, forms secondary seal structure, avoids appearing the fluid leakage in the use. Connect the filter screen card on the surface of fixed plate before the use, the fluid passes through the normal circulation of filter screen, and large granule thing in the fluid passes through the filter screen and filters and go out, avoids causing solenoid valve body to block up, and big particulate matter is collected by the surge drum again, and the spiral shell moves the surge drum and can handle large granule thing, simple structure, and convenient to use is fit for promoting.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

Referring to fig. 1-4, a direct-acting electromagnetic valve comprises a valve body 1, a filter screen 6, a collecting cylinder 10, a flange sleeve 12 and an elastic snap ring 13, wherein a valve rod 3 is arranged at the upper part of the valve body 1, a spring 2 is arranged in the valve rod 3, a spring diaphragm 4 is welded on the surface of the valve rod 3, a fixing plate 5 is welded at the inlet of the valve body 1, the fixing plate 5 is connected with the filter screen 6 in a buckling manner, a flexible clamping block 7 is welded on the filter screen 6, a clamping groove 8 is arranged inside the fixing plate 5, the flexible clamping block 7 is clamped in the clamping groove 8, a mounting frame 9 is fixed outside the valve body 1, the collecting cylinder 10 is communicated with the inside; the inlet and the outlet of the valve body 1 and the connecting pipe 11 are all welded with flange sleeves 12, the flange sleeves 12 are fixedly connected through bolts, the end of the connecting pipe 11 is welded with an elastic snap ring 13, a clamping groove 14 is arranged in the flange sleeve 12 connected with the valve body 1, and the elastic snap ring 13 is clamped in the clamping groove 14. Connecting pipe 11 makes the joint of snap ring 13 in joint groove 14 to the export of valve body 1, the extrusion of import surface before the use, forms preliminary seal structure, then fixes two sets of flange cover 12 through fixing bolt, forms the secondary seal, and the leakage of fluid such as water appears in avoiding the use, guarantees the leakproofness, and then guarantees the use quality.

Wherein, flexible fixture block 7 formula structure as an organic whole comprises round bar and the flexible lug of arc of fixing on its top, and the welding of round bar bottom is in the side surface of filter screen 6. The flexible lug of arc can be two sets of, welds respectively on the both sides surface on round bar top to the joint is in the inside of draw-in groove 8, and in the use, solenoid produces the electromagnetic force and mentions spring diaphragm 4 from the valve base, opens valve body 1, and the fluid passes through filter screen 6 earlier and gets into discharge in the valve body 1 again, and the large granule thing in the fluid receives the 6 separation of filter screen, avoids causing the jam to the inside of valve body 1. Because the mounting bracket 9 welds the lower surface at valve body 1, and sets up the side lower extreme at filter screen 6, and the inner wall of collecting vessel 10 threaded connection at mounting bracket 9 uses a period of back, and spiral shell moves collecting vessel 10 and takes off it, can handle the big particulate matter before the filter screen 6 inside valve body 1, simple structure facilitates the use. The cross-section of the elastic snap ring 13 is isosceles trapezoid, the cross-section of the clamping groove 14 is isosceles trapezoid which is matched with the elastic snap ring 13 and is concave inwards, the elastic snap ring 13 can be clamped in the clamping groove 14 in a labor-saving manner by adopting the structure, and meanwhile, the sealing performance can be ensured.

The utility model discloses rational in infrastructure, adopt double-deck seal structure to avoid the fluid leakage to can discharge large granule thing, prevent the inside jam of valve. When being connected solenoid valve body 1 and connecting pipe 11, both docks together, because of the elastic action of elasticity snap ring 13, final solenoid valve body 1 is sealed together with connecting pipe 11 through elasticity snap ring 13 joint, then passes through fixing bolt spiro union with flange cover 12 and fixes, forms secondary seal structure, avoids appearing the fluid leakage in the use. With 6 joints of filter screen on the surface of fixed plate 5 before the use, the fluid passes through the normal circulation of filter screen 6, and the large granule thing in the fluid passes through filter screen 6 and filters and go out, avoids causing solenoid valve body 1 to block up, and the large particle thing is collected by surge drum 10 again, and surge drum 10 can be handled large granule thing, simple structure, and convenient to use is fit for promoting.
