Abstract
The utility model is a guide type valve with electromagnetic, manual double controlling ways, comprising a valve body, a valve cover, a piston, an electromagnetic coil and an iron core. The utility model is characterized in that the valve cover of the main valve body is further provided with a pressure release flow channel and a needle shaped stop valve, so either the electromagnetic control or the manual control can open and close the valve, the lower cavity of the main valve piston is provided with a silicone rubber buffering diaphragm, which effectively reduces the impact force of the main valve piston and the 'water hammer' phenomenon, the valve rod of the needle shaped stop valve uses multiple start spiral, which can realize quick opening and closing by manually operation.
Description
Technical field: the utility model relates to solenoid valve, particularly a kind of can Electromagnetic Control, the leading type electromagnetism that can manually control again, manual double controlling valve.
Background technique: present normally used guide electromagnetic valve, be to open or close guide's pressure release runner hole by the motion of the moving iron core of solenoid controlled, make the main valve piston upper and lower cavity produce pressure difference and control moving up and down of main valve piston, thus the unlatching of control electromagnetic valve or close.In actual the use, owing to be subjected to the moving iron core of Electromagnetic Control promptly to open and close pressure release or supercharging, in valve body, produce bigger impact force, heavy caliber solenoid valve (more than the Dg50) particularly, when closing, also can be near valve build-up of pressure poor, form " water hammer " phenomenon, come and go in pipeline and propagate, this is disadvantageous to pipeline in the pressurized and equipment.In addition, as sudden power in electromagnetic coil damage or the system, solenoid valve then can not be opened.
Summary of the invention: the utility model is for solving the existing in prior technology defective, and design a kind of impact force that produces piston up-down can be alleviated the time, overcome " water hammer " phenomenon, and can Electromagnetic Control, the leading type electromagnetism that can manually control again, manual double controlling valve.
The technical solution adopted in the utility model is: leading type electromagnetism, manual double controlling valve, form by valve body, valve gap, piston and electromagnetic coil, iron core, it is characterized in that on the valve gap of main valve body, having set up a pressure release runner and pin type stop valve, cavity of resorption at main valve piston is provided with silicone rubber buffering barrier film, and the epicoele of the corresponding main valve piston in the medium inlet of main valve body has the throttle orifice of perforation.
The valve rod of pin type stop valve adopts multi-head spiral.
The technical solution of the utility model compared with prior art has the following advantages: the one, on the basis of former piston, increased the silicone rubber membrane of a buffer function, and alleviated impact force and " water hammer " phenomenon of main valve piston effectively; The 2nd, above the valve gap of main valve body, set up a pressure release runner, and opened and closed with pin type stop valve, reached the purpose that available manual control valve opens and closes; The 3rd, the valve rod of pin type stop valve has adopted the stainless steel multi-head spiral, can open and close (it is promptly able to turn on or off to rotate 120 degree approximately) apace.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
According to accompanying drawing embodiment embodiment of the present utility model is described below:
As shown in Figure 1, leading type electromagnetism, manual double controlling valve are made up of valve body, valve gap, piston and electromagnetic coil, iron core, a pressure release runner 12 and pin type stop valve 14 on the valve gap 10 of main valve body 8, have been set up, cavity of resorption at main valve piston 4 is provided with silicone rubber buffering barrier film 6, the epicoele 3 of the corresponding main valve piston 4 in the medium inlet of main valve body 8 has the throttle orifice 7,5 of perforation, wherein throttle orifice 7 is communicated with the medium inlet of main valve body 8 with main valve piston 4 cavity of resorptions, and throttle orifice 5 is communicated with main valve piston epicoele 3 with cavity of resorption.What the valve rod 13 of pin type stop valve 14 adopted is the stainless steel multi-head spiral, make pin type stop valve can open and close (rotate 120 degree approximately and can finish keying) apace, be provided with guide rod 9 in the middle of the main valve piston 4, pin type stop valve 14 is operated by the handle 15 of valve rod top.
Under the user mode, two pressure release runners 11,12 of valve are opened and closed by valve rod 13 controls of electromagnetism valve actuation iron core 2 and pin type stop valve 14 respectively.When electromagnetic coil 1 outage, the inlet of moving iron core 2 descending sealing pressure release runners 11, the medium that enters main valve piston 4 epicoeles 3 by throttle orifice 7,5 increases the main valve piston upper cavity pressure, the promotion main valve piston is descending, during to valve sealing face, silicone rubber buffering barrier film 6 is in extended state, thereby slowed down the downstream rate of main valve piston, near the valve pressure difference reduces, alleviated the impact force of main valve piston effectively, along with the continuation increase of main valve piston epicoele 3 pressure, main valve piston is close to valve sealing face, and main valve is reliably closed.During unlatching, electromagnetic coil 1 energising attracts moving iron core 2 to rise, and the medium that enters main valve piston epicoele 3 flows to outlet by pressure release runner 11, epicoele 3 hypotensions, and main valve can be opened.
Because solenoid valve is controlled two pressure release runners in parallel respectively with pin type stop valve, when power-off condition occurring, promptly available pin type stop valve is realized manually control.
