Background technology
Coal-mine hydraulic support is when using many logical blocks or many siphunculus, general support all can connect a large backwash filter on main inlet, and lead back on liquid and all will join a stop valve, support will be allowed like this to have more position to go to put these equipment, the working depth of certain ordinary stent is all more than 2 meters, and the space of putting some equipment is enough; But when girdle uses support, the placement location of these equipment will be very nervous, space even can not had to go to put these equipment (even if sometimes extruded the position of placing reluctantly when designing, during the use and maintenance of down-hole, people are also not easy to touch, and say nothing of maintenance and more exchange device); Under the constraint of this situation, manufacturing and designing all towards integrated miniaturization of current Bracket in Thin Coal Seam equipment.
Prior art one:
Hydraulic support in use, is installed after leading to one more, and can lead to in-line filter on this main inlet of block, this strainer is column type, and a termination is led to more, and a termination sebific duct also connects to control bound more; The strainer of this column type, once be blocked by impurity, will stop the emulsion by it, and the impurity along with blocking is more and more will make support motion more next slow, to finally slack; This column type strainer is multiple assembling parts, and filter screen is completely enclosed, if want to clear up the obstruction on filter screen, special tool must be used to dismantle on ground; We, when finding that many logical feed flows are not enough, just change this column type strainer (will note the model of interface during replacing, if model is not to connecting, cause the situation that cannot use) at once; This main liquid return hole needs placement external stop valve, is used for controlling back flow quantity.
Advantage: because strainer and stop valve are matured product, so dependable performance.
Shortcoming: strainer is once blocking, and the product of storehouse searching (or purchase) same size of just must sending someone, causes strainer not change in time like this, incur loss through delay the coal mining time; Because strainer and stop valve are all external, can, as spider, look in a mess lead to packaged joining so after more, also inconvenient during maintenance, and occupy very large space, cause the activity space of people narrower, operationally comfortableness is very poor to cause personnel.
Prior art two:
Design the form of many siphunculus, with the steel pipe of certain specification, use the method for plumb joint on the rear two ends of steel pipe press-bending and casing wall, it needs at least three pipes (comprising main feed tube, main liquid back pipe and water main); And many siphunculus are fixed in the front rod mechanism of support double leval jib, small-sized backwash filter and stop valve can be joined, material is thus formed the how logical structural system of conventional bracket of miniature version.
Advantage: solve the difficult problem changing strainer, after filter core plugs, pull several lower backwash filter, just obstruction can be rushed out, facilitate the use of product.
Shortcoming: will the front rod place moving on to quadric chain be led to more, although the place of putting many siphunculus increases, but the space of personnel activity is very crowded, trouble can be caused like this to maintenance, lead to if maintenance personal is just keeping in repair between back timber and base more, support, because certain reason reduces suddenly, at this moment can damage maintenance personal.
Summary of the invention
The object of this invention is to provide the how logical block of a kind of connection and built-in filter easy to maintenance, safety is high and built-in oil return cutout valve.
The object of the invention is to be achieved through the following technical solutions:
The how logical block of built-in filter of the present invention and built-in oil return cutout valve, main inlet, at least one this main inlet between the frame be interconnected is provided with in described many logical blocks, also be provided with main liquid return hole, at least one this main liquid return hole between the frame that is interconnected, be also provided with water main mouth, at least one this water main mouth between the frame that is interconnected;
In described the main inlet of frame, filtration core is installed;
Oil-break valve is installed back in described the main liquid return hole of frame.
As seen from the above technical solution provided by the invention, the how logical block of the built-in filter that the embodiment of the present invention provides and built-in oil return cutout valve, owing to installing filtration core in this main inlet, in this main liquid return hole, install back oil-break valve, connect and easy to maintenance, safety is high.
