Description

Technical Field

[0001] The utility model relates to the technical field of pipeline control, in particular to a four-channel electro-hydraulic integrated component. Background Art

[0002] Ball valves are currently the most advanced pipeline control equipment at home and abroad. They are mainly installed at the pump outlets of various pumping stations such as water conservancy, electricity, water supply and drainage, replacing the functions of check valves and gate valves. When working, the valve cooperates with the pipeline host, according to the principle of hydraulic transition process, through the preset opening and closing procedures, effectively eliminates pipeline water hammer, realizes reliable pipeline cutoff, and plays a role in protecting the safety of the pipeline system.

[0003] Domestic ball valve application technology is relatively mature, but in actual application, traditional ball valves have some defects, such as complex structure, adding reinforcing ribs to the hemispherical eccentric shaft to strengthen it, increasing the cavity structure, making the ball valve easy to clog; the sealing surface between the eccentric shaft and the valve body of the ball valve is small, making it easy to leak when used in a relatively harsh environment, short service life, and high maintenance rate. Therefore, the existing ball valve structure cannot be integrated together to form an integrated component to achieve independent control of opening and closing. Summary of the invention

[0004] The utility model provides a four-channel electro-hydraulic integrated component, which adopts four sets of ball rooms with independent valves, can realize independent control of opening and closing, and can be operated independently according to different needs. It has a simple structure, is not easy to be blocked, has good sealing performance, and has a long service life.

[0005] To achieve the above purpose, the technical solution of the utility model is: a four-channel electro-hydraulic integrated component, which is composed of four stop ball valves and four hydraulic drive mechanisms to form an integrated valve group, and the stop ball valve and the hydraulic drive mechanism are connected through a valve stem.

[0006] Furthermore, the integrated valve group includes a main valve block, an electromagnetic reversing valve and a signal sending box.

[0007] Furthermore, each main valve in the main valve block is connected to the electromagnetic reversing valve and the signal sending box.

[0008] Furthermore, each main valve includes a stop ball valve and a hydraulic drive mechanism. The stop ball valve is connected to the hydraulic drive mechanism via a valve stem, and the hydraulic drive mechanism drives the signal sending box.

[0009] Further, the hydraulic drive mechanism is composed of a hydraulically driven rack and pinion mechanism in the main valve, and the rack and pinion mechanism is connected to a signal rod of the signal sending box.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The four groups of ball valves are independent of each other and can be opened and closed individually, and can be operated independently according to different needs.

[0012] 2. Various operation modes. The four ball valves can be driven by remote control or manually operated independently through their own independent hydraulic drive mechanisms.

[0013] 3. Simple structure, not easy to be blocked, good sealing and long service life. BRIEF DESCRIPTION OF THE DRAWINGS
