Problems solved by technology

Obviously, the solenoid valve mentioned above is energized and de-energized through the coil to make the moving iron core move to control the outflow of liquid. At the same time, only when the coil is energized can the rubber head be kept separated from the inlet of the valve body to discharge the liquid. In actual production, some equipment needs to be turned on for a long time to keep the fluid in the discharge state, which requires the coil to be energized for a long time to maintain it, causing the coil energization time to be much longer than the power-off time. Therefore, in the equipment that needs to be normally open to maintain the fluid discharge state, The above-mentioned solenoid valve has the problems of high power consumption and high cost of use; at the same time, long-term energization will cause the coil to generate magnetic instability, resulting in the problem of exhaust failure

Embodiment 1

[0043] Such as figure 1 As shown, the present embodiment discloses a valve structure, which includes: a valve body, an inner cavity is formed in the valve body, in order to form the inner cavity, the structure of the valve body is not specifically limited, of course, for the convenience of processing, the The valve body is designed as several detachably connected or fixedly connected parts. In this embodiment, the valve body is designed as two pieces, namely the upper valve body 1 and the lower valve body 2. For processing and installation, generally It is designed that the upper valve body 1 and the lower valve body 2 are connected by bolts, and the upper valve body 1 and the lower valve body 2 enclose the inner cavity; Elastic diaphragm 5 is arranged, and described elastic diaphragm 5 generally selects elastic material to make, and in order to increase its certain rigidity, can add cord and / or stiffener plate etc. in elastic material, as described elastic material is rubber ...

Embodiment 2

[0050] Such as figure 2 with image 3 As shown, this embodiment discloses a valve structure, which is an improvement on the basis of Embodiment 1. The specific improvements are as follows: the inlets are set to two, respectively the first inlet 32 ​​and the second inlet 32. Two inlet ports 33; at the same time, a flow control valve chamber 34 is provided in the lower valve body 2, and a flow control valve assembly is arranged in the flow control valve chamber 34; the first inlet port 32 passes through the channel and The B chamber 7 communicates; the second inlet port 33 communicates with the B chamber 7 through the flow control valve chamber 34. At this time, the fluid passing through the second inlet port 33 is in the flow control Under the control of the valve assembly, it enters the B cavity 7 as required. The above arrangement can realize the use of one valve structure, and through the control of the flow control valve assembly, fluids of two pressures can be discharge...

Embodiment 3

[0056] Such as Figure 4-8 As shown, this embodiment discloses a solenoid valve device, which is an improvement on the basis of Embodiment 2, and the specific improvements are as follows: it also includes an electromagnetic assembly arranged on the upper valve body 1; the upper valve The body 1 is provided with an installation cavity 36, the electromagnetic assembly and the wall of the installation cavity 36 are enclosed to form a D cavity 10 and an E cavity 37, the D cavity 10 communicates with the A cavity 6, and the D cavity The chamber 10 communicates with or cuts off the atmosphere, and the E chamber 37 communicates with the B chamber 7; the electromagnetic assembly is used to switch the communication or isolation state between the D chamber 10 and the E chamber 37, and the electromagnetic assembly is powered on. , the D chamber 10 communicates with the E chamber 37, and further, the D chamber 10 communicates with the B chamber 7 through the E chamber 37. At this time, th...

Abstract

The invention discloses a valve structure. When fluid with certain pressure enters a cavity B through a flow inlet and the pressure overcomes the elastic force of an elastic membrane to extrude a cavity A upwards, the cavity B is communicated with a cavity C, and at the moment, the fluid in the cavity B enters the cavity C and then enters a flow outlet to be discharged. By means of the arrangement, industrial fluid can be discharged through a valve body, the structure can be used for a long time without being powered on, the problem of power consumption is solved, meanwhile, the structure is not powered on, and the problem of discharge failure caused by unstable magnetic force in the using process is also solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a drain valve and a solenoid valve device. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. The fluid is generally liquid, gas or a combination of liquid and gas. It controls the opening of the solenoid valve channel through the gain and loss of solenoid valve coil. and closed to allow fluid to pass through and shut off the channel. Such as, [0003] The Chinese utility model patent with the notification number CN205136615U discloses a solenoid valve, which includes a valve body and a coil. There is a sleeve between the valve body and the coil. A moving iron core is arranged inside the casing, a static iron core is arranged above the moving iron core, a large spring and a small spring are arranged in the moving iron core, the large spring and the small spring are offse...
