Description

Technical Field

[0001] The utility model mainly relates to the technical field of two-way cartridge valves, in particular to a sealing monitoring mechanism for a two-way cartridge valve. Background Art

[0002] The two-way cartridge valve has the characteristics of sensitive action, fast response and small impact; strong resistance to oil pollution and no strict requirements on oil filtration accuracy; simple structure, easy maintenance, few failures and long service life; the plug-in has the characteristics of one valve with multiple functions, which is convenient for forming various hydraulic circuits and works stably and reliably; the plug-in has parts with a high degree of universality, standardization and serialization, and can form an integrated system.

[0003] Since the cartridge of the two-way cartridge valve needs to be inserted into the integrated valve block, it becomes difficult to monitor the sealing of the two-way cartridge valve. If it is not discovered in time, it will have a significant impact on subsequent work. In addition, problems such as dirt in the oil or processing accuracy will cause the valve core to get stuck on the valve sleeve, affecting normal work. Utility Model Content

DETAILED DESCRIPTION

[0014] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.

[0015] like Figure 1-2 As shown, a two-way cartridge valve sealing monitoring mechanism described in the utility model comprises an integrated valve block 1, a control cover plate 2 is installed on the top of the integrated valve block 1, a valve sleeve 3 is slidably installed inside the integrated valve block 1, a first valve core 4 and a second valve core 5 are arranged inside the valve sleeve 3, the first valve core 4 and the second valve core 5 are both in contact with the valve sleeve 3 through a sealing ring 6, battery blocks 7 are installed on both sides of the bottom of the valve sleeve 3, a first pole piece 8 is installed on the top of the battery block 7, a connecting plate 11 is installed on the top of the battery block 7 through a spring 9, a second pole piece 13 is installed on the bottom of the connecting plate 11 through a vertical rod 12, a pressure rod 15 is installed on one side of the bottom of the first valve core 4 and the second valve core 5 through a horizontal plate 14, each of the pressure rods 15 can contact and cooperate with the corresponding connecting plate 11, and indicator lights 16 are installed on both sides of the top surface of the integrated valve block 1, and the indicator lights 16 are respectively connected to the first pole piece 8 and the second pole piece 13.

[0016] Specifically, a pilot valve 10 is installed on the top surface of the control cover plate 2 .

[0017] Specifically, the sealing ring is an EPDM rubber ring.

[0018] Example:

[0019] When using the device, when the two-way cartridge valve is normally closed, the first valve core 4 and the second valve core 5 will be tightly combined with the valve sleeve 3, and with the cooperation of the sealing ring 6, a good seal will be formed. At this time, the pressure rod 15 will press the connecting plate 11 downward, thereby driving the second pole piece 13 to move downward and contact with the second pole piece 8, forming an electrical circuit, thereby making the indicator light 16 work and light up. The normal lighting of the indicator light 16 proves that the seal is good at this time.

Through the cooperation of the first pole piece, the second pole piece and the indicator light, the internal sealing is monitored by turning on and off the indicator light, thereby achieving the effect of real-time monitoring of the internal sealing. At the same time, by setting two indicator lights, the sealing of the first valve core and the second valve core can be monitored at the same time, thereby bringing convenience to the monitoring of the sealing.
