A communication channel is arranged between the oil inlet hole and the oil outlet, a bypass valve is arranged in the communication channel, and a signal transmitter used for prompting overlarge pressure difference is fixed on one side of the upper shell.
Furthermore, a processing process hole is formed in the upper shell.
Furthermore, the lower casing is internally provided with an elastic part for stabilizing the filter element, and the elastic part is positioned below the filter element.
Furthermore, a first sealing washer is fixed above the lower shell, a second sealing washer is sleeved on the outer wall of the lower shell, and the second sealing washer is located at one end, close to the first sealing washer, of the lower shell.
The utility model has the advantages that:
1. the utility model discloses the filter is through installing this filter on the valve block, and fluid enters into the inside of lower casing through the inlet port of valve block, filters the impurity in the fluid through the filter core, and the fluid after the filtration flows out to the oil outlet of valve block through the oil-out, and then enters into next hydraulic component, and this filter simple structure is suitable for the practicality;
2. the utility model discloses the filter is through setting up signal transmitter and bypass valve, when avoiding the filter core of filter to take place to block up, because of the operating pressure differential between inlet port and the oil outlet can increase, the abnormal operation of the system that causes.
Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic view of the filter of the present invention;
fig. 2 is a schematic diagram of the cross-sectional structure of the filter of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The utility model provides a low temperature resistant high pressure filter, filter include casing 1 and last casing 2 down, as shown in fig. 1, fig. 2, threaded connection between casing 1 and the last casing 2 down is equipped with filter core 3 in the casing 1 down, is equipped with the inlet port 4 with casing 1 intercommunication down on going up casing 2, is equipped with the oil outlet 5 with filter core 3 intercommunication on going up casing 2, goes up and is equipped with the oil drain hole 7 with oil outlet 5 intercommunication on the casing 2.
The upper shell 2 is provided with a processing fabrication hole 6.
Be equipped with the elastic component 9 that is used for stabilizing filter core 3 in the casing 1 down, elastic component 9 is located the below of filter core 3, and the top of casing 1 is fixed with first seal ring 10 down, and the cover is equipped with second seal ring 11 on the outer wall of casing 1 down, and second seal ring 11 is located the one end that casing 1 is close to first seal ring 10 down.
A communication channel is arranged between the oil inlet 4 and the oil outlet 5, a bypass valve 7 is arranged in the communication channel, and a signal transmitter 12 for prompting overlarge pressure difference is fixed on one side of the upper shell 2.
When the working pressure difference between the oil inlet hole 4 and the oil outlet hole 5 reaches a set pressure value, the alarm is given through the signaling device 12 to prompt the shutdown for replacing the filter element, and under the condition that the filter element is not replaced in time, the working pressure difference between the oil inlet hole 4 and the oil outlet hole 5 continuously rises to the pressure difference value set by the bypass valve 7 in the filter, the bypass valve 7 is automatically opened, and the oil inlet hole 4 and the oil outlet hole 5 of the filter are communicated.
