Further, the top plug screw adopts a damping plug screw.
Compared with the prior art, the utility model has at least the following beneficial effects:
the utility model can integrate the flushing valve on the pump body, simplifies the system, reduces the space occupied by the system, and solves the problem that the flushing valve cannot be integrated on the motor due to insufficient installation space. In addition, the utility model has reliable performance and simple structure, and greatly reduces the production cost.
Drawings
Fig. 1 is a schematic view of the overall structure of a pump-integrated flush valve of the present utility model.
Detailed Description
The pump-integrated flush valve of the present utility model will be described in more detail below in conjunction with the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art could modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1, an embodiment of the present utility model provides a flush valve integrated on a pump, including a valve body 6, two oil paths connected with a pump body are provided on the valve body 6, valve spools 5 are provided at the ends of the oil paths, a valve rod is provided between the two valve spools 5, an elastic component is provided at the outer end of the valve spool 5, and the elastic component is detachably mounted on the valve body 6.
In the present embodiment, the size of the installation surface of the valve body 6 is in accordance with the A, B oil port installation size of the HP4VC28 pump, and the present utility model can be integrated on the HP4VC28 pump. The two ends of the valve core 5 are communicated with the A, B port of the pump. When the flushing valve works, the pressure on the high pressure side pushes the valve core 5 to change direction, so that the low pressure side is communicated with the oil tank, and the low pressure oil liquid has partial heat and impurities, thereby playing a role in system heat dissipation and oil cleaning.
Further, the elastic component comprises a spring seat 4 which is abutted against the valve core 5, one end of the spring seat 4, which is away from the valve core 5, is elastically connected with a sealing screw plug 1 through a connecting spring 3, the sealing screw plug 1 is detachably arranged on the valve body 6, and the sealing screw plug 1 is in threaded installation on the valve body 6.
Specifically, when the oil high-low pressure end control is performed, the compression amount of the connecting spring 3 can be adjusted by the screwing degree of the sealing screw plug 1, and when the compression amount of the connecting spring 3 is increased, the pressure of the connecting spring 3 to the valve core 5 is increased. Similarly, when the compression amount of the connection spring 3 decreases, the pressure of the connection spring 3 against the valve spool 5 decreases.
In order to improve the air tightness between the sealing screw plug 1 and the valve body 6, an O-shaped sealing ring 2 is arranged between the sealing screw plug 1 and the valve body 6.
Further, the end of the oil passage is provided with a protection plug screw 9.
Specifically, in order to avoid the pollution or the blockage of the oil circuit before the flushing valve is not used, the end part of the oil circuit is provided with a protection piston, and the installation mode of the protection piston can be clamping connection or nut connection, so that the end part of the oil circuit can be plugged. When the flush valve is to be used, the protective screw plug 9 can be removed and attached to the pump body.
Further, an adjusting oil way is arranged in the middle of the valve body 6, a bottom screw plug 7 and a top screw plug 8 are respectively arranged at two ends of the adjusting oil way, and the top screw plug 8 adopts a damping screw plug.
In particular, when there is a demand for the flushing flow of the flushing valve, the adjustment can be made by changing the damping orifice of the damping screw plug.
Compared with the prior art, the utility model has at least the following beneficial effects:
the utility model can integrate the flushing valve on the pump body, simplifies the system, reduces the space occupied by the system, and solves the problem that the flushing valve cannot be integrated on the motor due to insufficient installation space. In addition, the utility model has reliable performance and simple structure, and greatly reduces the production cost.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
