Abstract
The utility model relates to a reversing valve with working pressure of 31.5 MPa, which comprises a valve body and an operating mechanism, wherein an upper working chamber and a lower working chamber are arranged on the valve body, the upper working chamber is communicated with a chamber A, the lower working chamber is communicated with a chamber B, the two points of the upper working chamber and the lower working chamber are communicated with each other and pass through a liquid inlet and outlet, the upper working chamber and the lower working chamber have the same structure, locating sleeves with valve rod assemblies are screwed at the right end of the upper working chamber and the lower working chamber, and the left end is orderly provided with an upper valve sleeve, a valve stem, a middle valve sleeve, a valve seat, a lower valve sleeve and a spring seat which is made of stainless steel and used for storing a spring. When an end block is screwed tightly, the end head of the spring seat forms a conical surface to be fitted with a sealing surface of the valve seat. The utility model has the advantages of compact structure, light weight, convenient installation and maintenance and reliable sealing performance, and is used for a hydraulic support for a coal mine fully-mechanised working face.
Description
One, affiliated technical field
The utility model relates to a kind of reversal valve, and referring in particular to a kind of operating pressure that is used for the coal mine fully-mechanized mining working hydraulic support is the reversal valve of 31.5MPa.
Two, background technology
In the colliery industry, also there is the people reversal valve to be called " control valve " or " control valve ".Reversal valve in the hydraulic support control system, control liquid flow path direction, the different actions such as realizing the hydraulic support lifting, pass, try to stop people from fighting each other, side guard board is stretched receipts, receipts are stretched by sheet nation.But the reversal valve volume that present operating pressure is 31.5MPa is big, Heavy Weight, and installation and maintenance inconvenience, and adopt the steel ball sealing structure, the seepage phenomenon appears in reasons such as invar ball corrosion, is difficult to guarantee the down-hole instructions for use.If reversal valve is disabled, will seriously influence the operate as normal of hydraulic support, cause work plane to stop production.
Three, utility model content
It is the reversal valve of 31.5MPa that the purpose of this utility model is to provide a kind of operating pressure, its compact conformation, and in light weight, convenient for installation and maintenance, sealing performance is reliable.
For achieving the above object, the solution that the utility model is taked is: a kind of operating pressure is the reversal valve of 31.5MPa, it comprises valve body, operating mechanism, valve body has working chamber and following working chamber, last working chamber communicates with the A chamber, following working chamber communicates with the B chamber, last working chamber communicates with following working chamber two places and leads to the liquid in-out mouth, last working chamber is identical with following working chamber structure, be screwed into the positioning sleeve of being with valve rod assembly at last working chamber and following working chamber right-hand member, put into upper valve sleeve successively from left end, valve rod, middle valve pocket, valve seat, lower valve sleeve, the spring-loaded spring base of making by stainless steel, it is stifled to tighten end, and the termination of spring base is that the conical surface cooperates with sealing surface of seat.
The utility model compact conformation, volume is little, and weight ratio has been saved raw material with the light 30%-50% of like product of working flow, has reduced cost of production widely.Owing to adopt the stainless steel conical surface seal, than the existing steel ball sealing structure that adopts, sealing performance is more reliable, and the seepage phenomenon of having avoided the corrosion of invar ball to occur.Adopt the screw plug formula to tighten structure, installation and maintenance are more convenient.
Four, description of drawings
Fig. 1 is the main pseudosection of present embodiment (when operating mechanism is upwards pulled to the operating position).
Among the figure: 1, end is stifled, and 2, spring, 3, spring base, 4, lower valve sleeve, 5, valve seat, 6, middle valve pocket, 7, valve rod, 8, upper valve sleeve, 9, valve rod assembly, 10, positioning sleeve, 11, valve body, 12, operating mechanism, 13, go up working chamber, 14, working chamber down, 15, the A chamber, 16, B chamber, 17, the liquid in-out mouth, 18, double-screw bolt series connection hole.
Five, the specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of operating pressure is the reversal valve of 31.5MPa, it comprises valve body 11, operating mechanism 13, valve body 11 has working chamber 13 and following working chamber 14, last working chamber 13 communicates with A chamber 15, following working chamber 14 communicates with B chamber 16, last working chamber 13 is located to communicate and logical liquid in-out mouth 17 with 14 liang of following working chambers, last working chamber 13 is identical with following working chamber 14 structures, be screwed into the positioning sleeve 10 of being with valve rod assembly 9 at last working chamber 13 and following working chamber 14 right-hand members, put into upper valve sleeve 8 successively from left end, valve rod 7, middle valve pocket 6, valve seat 5, lower valve sleeve 4, the spring base of making by stainless steel 3 of shock mount 2, tighten end and block up 1, the termination of spring base 3 is that the conical surface cooperates with valve seat 5 sealing surfaces.
Referring to Fig. 1, valve body has double-screw bolt series connection hole 18 for 11 4 jiaos, is convenient to multi-disc valve tandem compound.
The effect of present embodiment is each working chamber that the liquid that pumping comes is assigned to support, to finish setting prop, fall post, pushing and sliding, to move frame and push away job such as receiving the side guard board jack.Its operating principle is: when operating mechanism 13 mediated, the interface that leads to each working chamber all communicated with liquid back pipe.When operating mechanism 13 is upwards pulled to the operating position, last working chamber 13 is admission chambers, the gap of highly pressurised liquid between valve rod 7 and valve seat 5 flows into A chamber 15, enter the feed flow chamber of bracket jack, be in back liquid status with working chamber 14 at present, the liquid that bracket jack is returned sap cavity can freely enter the gap between valve rod assembly 9 and the valve rod 7 from B chamber 16.Realize work such as setting prop with this.On the contrary, when operating mechanism 13 is pulled to the operating position downwards, then realize falling work such as post.
Present embodiment is a FLFHS125/31.5 type reversal valve, rated operating pressure: 31.5MPa, nominal operation flow: 125L/min, minimum latus rectum: Φ 10, lever operated moment≤10NM, appearance and size (monolithic): 292 * 100, working media is 5% emulsion, can be under 10-50 ℃ of liquid temperature operate as normal.It also can be according to the matched bracket action request, is formed with the double-screw bolt tandem compound by first plate valve, several middle plate valves and cauda valve.
