Description
Technical field
The utility model belongs to hydraulic control valve technical field, and in particular to a kind of external overflow valve installation module.
Background technique
Usual hydraulic multitandem valve is reserved with overflow valve installation space in design Shi Douhui, selectively installs in corollary system
Overflow valve or oil are stifled, can generate certain waste in actual production, overflow valve jack first requires to process, and does not need to be arranged
Jack is blocked when overflow valve, forms dual waste.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of external overflow valve installation mould
Block.
The utility model is achieved by the following technical solution: a kind of external overflow valve installation module, including pedestal,
Pedestal is equipped with through-hole and blind hole, and overflow valve is mounted in blind hole, the pipe fitting through through-hole is equipped in through-hole, pipe fitting side wall is set
There is oil outlet；It is equipped with oil unloading trough I in blind hole, is equipped in oil unloading trough I by the oil outlet of oil liquid discharge pedestal, and oil unloading trough I and overflows
The oil outlet of stream valve is connected；Oil unloading trough II is equipped in through-hole, oil unloading trough II is connected with the oil outlet of pipe fitting and blind hole respectively.
Further, the pedestal shape is cylindrical or cuboid shape.
Further, the oil outlet of the pipe fitting is the through hole being located on tube wall.
Further, the tube wall of the pipe fitting is equipped with the through hole of two groups of right-angled intersections.
The pipe fitting both ends of the utility model are equipped with screw thread, will be originally practical new when hydraulic multitandem valve needs to install overflow valve
Pipe fitting one end of type external overflow valve installation module is mounted on the oil outlet of hydraulic multitandem valve, and the other end of pipe fitting is mounted on liquid
The purpose of hydraulic multitandem valve installation overflow valve can be realized in the oil inlet of pressure element；Installation overflow valve is not needed in hydraulic multitandem valve
When, the external overflow valve installation module of the utility model is removed, the oil inlet of Hydraulic Elements is directly connected with hydraulic multitandem valve
It connects.The utility model is eliminated reserves overflow valve installation space on hydraulic multitandem valve, also avoids in hydraulic multitandem valve
It does not need using the trouble for needing to block overflow valve installation space when overflow valve using oil.
The beneficial effects of the utility model are: the utility model simple structure facilitates manufacture to install, it can be according to hydraulic multichannel
The actual needs of valve output oil port carries out selective installation, easy to use, flexible in application, avoids problem inconvenient for use.

Specific embodiment
Below according to drawings and examples, the present invention will be further described.
As shown in Figure 1 to Figure 3, a kind of external overflow valve installs module, including pedestal 2, and pedestal 2 is equipped with through-hole 2-1
With blind hole 2-2, overflow valve 1 is mounted on blind hole 2-2, and the pipe fitting 3 through through-hole 2-1,3 side wall of pipe fitting are equipped in through-hole 2-1
Equipped with oil outlet, connection function is played at the both ends of pipe fitting 3, and the hollow pipeline of pipe fitting 3 is used for the transport of oil liquid, on 3 side wall of pipe fitting
Oil outlet for the oil liquid in pipe fitting 3 to be separated；I 2-21 of oil unloading trough is equipped in blind hole 2-2, being equipped in I 2-21 of oil unloading trough will
The oil outlet of pedestal 2 is discharged in oil liquid, and I 2-21 of oil unloading trough is connected with the oil outlet of overflow valve 1；Emptying is equipped in through-hole 2-1
II 2-11 of slot, II 2-11 of oil unloading trough are connected with the oil outlet of pipe fitting 3 and blind hole 2-2 respectively.Between pipe fitting 3 and pedestal 2 and base
Sealing ring is equipped between seat 2 and hydraulic multitandem valve.The both ends of pipe fitting 3 are equipped with screw thread, pipe fitting 3 and next stage Hydraulic Elements and liquid
The oil outlet of pressure multi-way valve is all made of threaded connection.It is additionally provided with bolt hole on pedestal 2, when the utility model is used, by pedestal 2
It is bolted on hydraulic multitandem valve.
Further, 2 shape of pedestal is cylindrical or cuboid shape.
As the improvement of the present embodiment, the oil outlet of the pipe fitting 3 is the through hole being located on tube wall, and oil liquid is facilitated to flow out
Pipe fitting 3.Further, the tube wall of the pipe fitting 3 is equipped with the through hole of two groups of right-angled intersections, and multiple oil outlets increase
The output speed of oil liquid.
As shown in Figures 2 and 3, the utility model is mounted on hydraulic multitandem valve, oil liquid by pipe fitting enter it is next
When grade Hydraulic Elements, a part of oil liquid enters in oil unloading trough II from the outflow of the oil outlet of pipe fitting tube wall, and oil liquid passes through oil unloading trough again
II enters blind hole, and after the oil liquid pressure in blind hole reaches overflow valve threshold values, oil liquid flows into overflow valve valve from blind hole again, then
Oil liquid enters in oil unloading trough I from the outflow of the oil outlet of overflow valve, then flows into oil cylinder from the oil outlet of oil unloading trough I, realizes that level pressure is overflow
Stream, pressure stabilizing, system unloaded and safeguard protection effect.When hydraulic multitandem valve is not needed using overflow valve, the utility model is taken
Under, then next stage Hydraulic Elements are directly connected with the oil outlet of hydraulic multitandem valve.
