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
The present invention relates to a kind of hydraulic multitandem valve with transshipping Fill valve, particularly a kind of proportional multi-path valve is with transshipping Fill valve.
Background technique
The patent No. is that the Chinese patent of ZL96248550 discloses a kind of integral multi-way valve with transshipping Fill valve, this integral multi-way valve is big with overload Fill valve axial dimension, complex structure uses to be restricted on the proportional multi-path valve, can not satisfy the proportional multi-path valve arrangement needs are installed.
Summary of the invention
Technical problem to be solved by this invention provides a kind of proportional multi-path valve with transshipping Fill valve, the technological scheme that it adopts is: a kind of proportional multi-path valve is with transshipping Fill valve, comprise valve seat, the seal ring that matches with valve seat, place repairing spring, repairing spring seat and overload spring in the valve seat, also comprise the overload spring seat with overload spring coupling, and the overload spool that is connected with the overload spring seat with the repairing spring seat, wherein said repairing spring is a tapered coil spring.
The present invention further technical characteristics is:
Described overload spool is connected with the overload spring seat with the repairing spring seat by repairing valve seat and connecting rod.
Described repairing spring seat is a bidirectional spring seat up and down, and it is provided with interior threaded hole.
Described connecting rod is provided with outside thread.
The invention has the beneficial effects as follows: because a kind of proportional multi-path valve of the present invention is a tapered coil spring with repairing spring in the overload Fill valve, pressing also, height can be low to moderate spring steel silk thread footpath size, therefore axially installation dimension reduces significantly, satisfies the needs of proportional multi-path valve arrangement size fully.
Description of drawings
Fig. 1 is a structure sectional view of the present invention;
Fig. 2 is the assembling schematic representation of the present invention and proportional multi-path valve.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Referring to figs. 1 through shown in Figure 2, a kind of proportional multi-path valve is with transshipping Fill valve, comprise valve seat 1, the seal ring 2 that matches with valve seat 1, place repairing spring 3, repairing spring seat 4 and overload spring 5 in the valve seat 1, also comprise the overload spring seat 6 with overload spring 5 coupling, and the overload spool 8 that is connected with overload spring seat 6 with repairing spring seat 4, wherein said repairing spring 3 is a tapered coil spring.
In the embodiment shown in fig. 1, described overload spool 8 is connected with overload spring seat 6 with repairing spring seat 4 by repairing valve seat 7 and connecting rod 9.
Described repairing spring seat 4 is a bidirectional spring seat up and down, and it is provided with interior threaded hole.
Described connecting rod is provided with outside thread.
As required, in actual applications, described overload spool 8 and connecting rod 9 can also be designed to monolithic construction.
The assembling schematic representation of the present invention and proportional multi-path valve is with reference to Fig. 2, repairing spring seat 4, overload spring 5, overload spring seat 6 and repairing valve seat 7 are fitted together earlier in advance by overload spool 8 (overload spool 8 described in the present embodiment and connecting rod 9 are monolithic construction), thereby adjust the decrement of overload spring 5 at certain limit adjustment overload pressure by screwing repairing spring seat 4.The part overload Fill valve that installs in advance above-mentioned pack into Proportional valve valve body 11 in the hole that is complementary, put repairing spring 3 above, in the screw 12 that behind the seal ring 2 of on valve seat 1, packing into valve seat 1 is screwed on the Proportional valve valve body.
When the pressure of working oil chamber 9 surpassed the predefined pressure of overload Fill valve, overload spool 8 was pushed and moves downward, and leaves repairing valve seat 7, and high pressure oil flows to oil back chamber 10 from working oil chamber 9, realizes overload protection.
When negative pressure appears in the pressure of working oil chamber 9, the pressure height of oil back chamber 10 the insides, promote whole group prepackage overload Fill valve, repairing spring 3 is compressed, valve seat 7 leaves the hole that is complementary on the Proportional valve valve body 11 that matches simultaneously, the oil of oil back chamber 10 the insides flows to working oil chamber 9, realizes the repairing action.
Because a kind of proportional multi-path valve of the present invention is a tapered coil spring with repairing spring in the overload Fill valve, to press also highly to be low to moderate spring steel silk thread footpath size, therefore axial installation dimension reduces significantly, satisfies the needs of proportional multi-path valve arrangement size fully.
