Description
Technical field
It is the hand-operated direction valve of medium that the utility model relates to the emulsion, especially relates to the big flow plug-in hand-operated direction valve that is used on the hydraulic support.
Background technology
Along with the raising of ore deposit pressure and mining height standard, some big hydraulic cylinder is also more and more big to the high flow directional control valve demand on the support, and all there are various deficiencies in domestic and international similar high flow directional control valve at aspects such as functional reliability and processing technologies at present; Adopt the valve rod of metal material and the formed cone seal pair of polyformaldehyde material valve seat to realize sealing to the feed liquor valve port making contamination resistance relatively poor as the feed liquor hermetically-sealed construction of valve body; And because the axiality of parts such as valve body end bell and spigot joint, valve rod, valve seat, spacing middle cover requires height, the difficult assurance in the actual processing caused the sealing reliability reduction of valve rod and valve base chamber; And when maintenance, valve rod, valve seat, spacing middle cover, bar cover and depression bar assembly can not form integral plugged formula, make installing/dismounting also very inconvenient.
The utility model content
The utility model purpose is to provide that a kind of dismounting is convenient, the big flow plug-in of the hydraulic support of good sealing effect hand-operated direction valve.
For achieving the above object, the utility model can be taked following technical proposals:
The big flow plug-in hand-operated direction valve that is used on the hydraulic support described in the utility model, two position three-way valve and the operating mechanism identical by two structures constitute; Described two position three-way valve is made up of valve body and the spool that is arranged in its through-hole structure valve pocket; The integral plugged valve string structure of screw-type that described spool is made up of feed liquor valve, feed liquor sealing mat, spacing middle cover, time liquid valve, time liquid sealing pad, coupling ring spare, bar cover and depression bar assembly from left to right successively; Described feed liquor valve right output port inner peripheral surface is threaded with time liquid valve left port outer peripheral face; Described spacing middle cover is set in back liquid valve outer peripheral face; Described feed liquor sealing mat be sleeved on back liquid valve outer peripheral face feed liquor valve right output port and spacing in the cover left port between; Described depression bar assembly is arranged in the bar cover, and its left end extends outside the loop bar and links with described operating mechanism, and its right side is a blind hole structure, and it is stifled to be fitted with hollow T-valve in the blind hole, and described time the liquid sealing cushion cover is loaded on the stifled outer peripheral face of hollow T-valve; Cover is connected by described coupling ring with the bar cover in spacing; Described valve pocket left port is provided with spring strut and the compression spring that places in it by screw thread; Described spring strut right-hand member extends to feed liquor valve left port, and the spring strut left port is extended outside the valve pocket with the end bell and spigot joint and is connected.
The utility model advantage is that described feed liquor sealing valve port form is the flat seal pair of spacing middle cover with the feed liquor sealing mat composition of soft sealing material of metal material, contamination resistance is strong, owing to be the flat seal pair, axiality to parts such as valve body, end bell and spigot joint, feed liquor valve, time liquid valve, spacing middle covers requires relatively low, good manufacturability, be easy to guarantee in the actual processing, improved sealing reliability; Member feed liquor valve, feed liquor sealing mat, spacing in cover, return the liquid valve, return the liquid sealing pad, coupling ring, bar cover and depression bar assembly take the screw-type can integral plugged valve string structure, it is very convenient therefore to safeguard under the mine of adverse circumstances.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the big flow plug-in hand-operated direction valve that is used on the hydraulic support described in the utility model, two position three-way valve and the operating mechanism 13 identical by two structures constitute; Described two position three-way valve is made up of valve body 3 and the spool that is arranged in its through-hole structure valve pocket; The integral plugged valve string structure of screw-type that described spool is made up of feed liquor valve 4, feed liquor sealing mat 6, spacing middle cover 7, time liquid valve 8, time liquid sealing pad 9, coupling ring 10, bar cover 11 and depression bar assembly 12 from left to right successively; Described feed liquor valve 4 right output port inner peripheral surfaces are threaded with time liquid valve 8 left port outer peripheral faces; Described spacing middle cover 7 is set in back liquid valve 8 outer peripheral faces; Described feed liquor sealing mat 6 be sleeved on back liquid valve 8 outer peripheral faces feed liquor valve 4 right output port and spacing in the cover 7 left port between; Described depression bar assembly 12 is arranged in the bar cover 11, and its left end extends outside the loop bar 11 and links with described operating mechanism, and its right side is a blind hole structure, and it is stifled to be fitted with hollow T-valve in the blind hole, and described time liquid sealing pad 9 is set in the stifled outer peripheral face of hollow T-valve; Cover 7 and bar overlap 11 and are connected by described coupling ring 10 in spacing; Described valve pocket left port is provided with spring strut 2 and the compression spring that places in it by screw thread; Described spring strut 2 right-hand members extend to feed liquor valve 4 left port, and spring strut 2 left port are extended outside the valve pocket with end bell and spigot joint 1 and are connected.
The utility model operating principle is as follows:
When meta is moved the handle 16 of operating mechanism 13 up or down, promote depression bar assembly 12 to left movement by the cam mechanism in the operating mechanism 13, along with moving to, depression bar assembly 12 contacts back liquid valve 8 right-hand members left, the liquid valve port that returns that then returns liquid valve pad 9 and return between liquid valve 8 right-hand members is closed, returning the liquid oil duct is sealed, depression bar assembly 12 promotes back liquid valve 8 simultaneously, feed liquor sealing mat 6 and feed liquor valve 4 are moved to the left, cover 7 is opened the feed liquor valve port with time liquid valve 4 and 6 disengagings of feed liquor sealing mat respectively in spacing, P mouth hydraulic oil is successively by holding the inclined hole of bell and spigot joint spare 1 right-hand member like this, the oil duct (being the feed liquor valve port) that cover 7 forms respectively and between feed liquor valve 4 and the feed liquor sealing mat 6 in spacing, aperture through returning on liquid valve 8 circumference flows into endoporus again, after the endoporus of feed liquor valve 4 and end bell and spigot joint 1 flow to working hole A or B mouth, the hydraulic oil of A or B mouth enters the work of hydraulic oil cylinder driving operating cylinder.
When the handle 16 of operating mechanism 13 is in meta, under the effect of spring strut 2 internal pressure springs, feed liquor sealing mat 6 forms sealing surface with spacing middle cover 7 left sides, the feed liquor valve port is sealed, simultaneously under lever 14 effects, returning liquid valve pad 9 and depression bar assembly 12 all is separated with the right-hand member of feed liquor valve 8, returning the liquid valve port is opened, when the oil cylinder inner fluid returns liquid like this, return liquid from oil cylinder to reversal valve working hole A or the B mouth, through end bell and spigot joint 1, feed liquor valve 4, return the endoporus of liquid valve 8, again through returning time liquid valve port between liquid valve 8 right sides and depression bar assembly 12 left sides, again in spacing the cover 7 circumference on orifice flow to the O mouth, realize that in-oil cylinder fluid returns liquid.
