Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] refer to Figure 1 to Figure 2 As shown, an overload charge valve for a proportional multi-way valve includes a valve seat 1, a sealing ring 2 matched with the valve seat 1, an oil charge spring 3 placed in the valve seat 1, an oil charge spring seat 4 and an overload The spring 5 also includes an overload spring seat 6 matched with the overload spring 5, and an overload spool 8 connected with the oil supply spring seat 4 and the overload spring seat 6, wherein the oil supply spring 3 is a conical coil spring.

[0013] exist figure 1 In the shown embodiment, the overload spool 8 is connected with the oil charge spring seat 4 and the overload spring seat 6 through the oil charge valve seat 7 and the connecting rod 9 .

[0014] The oil-charging spring seat 4 is an up and down two-way spring seat, and an internally threaded hole is arranged on it.

[0015] The conne...

Abstract

The invention discloses an overload oil compensation valve for a proportional multi-way valve. The overload oil compensation valve comprises a valve seat, a sealing ring which is matched with the valve seat, an oil compensation spring, an oil compensation spring seat and an overload spring which are arranged in the valve seat, an overload spring seat which is matched with the overload spring, and an overload valve core which is connected with the oil compensation spring seat and the overload spring seat, wherein the oil compensation spring is a conical spiral spring. The oil compensation spring in the overload oil compensation valve for the proportional multi-way valve is the conical spiral spring, and a compressed height can be as short as the wire diameter of the steel wire of the spring, so that an axial installation dimension is greatly reduced, and the requirement of the structural dimension of the proportional multi-way valve is completely met.

Description

technical field [0001] The invention relates to an overload oil supply valve for a hydraulic multi-way valve, in particular to an overload oil supply valve for a proportional multi-way valve. Background technique [0002] The Chinese patent with the patent number ZL96248550 discloses an overload oil supply valve for an integral multi-way valve. The overload oil supply valve for an integral multi-way valve has a large axial dimension and a complex structure, and its use on proportional multi-way valves is limited. , can not meet the structural installation needs of the proportional multi-way valve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overload replenishment valve for a proportional multi-way valve. The technical solution it adopts is: an overload replenishment valve for a proportional multi-way valve, including a valve seat, which is matched with the valve seat The sealing ring, the oil charge sprin...
