Abstract
The utility model relates to a kind of hydraulic pressure valve rubber compensation type one-way valve being convenient to safeguard, comprises valve gap, guide sleeve, valve spring, valve rubber extruding means, valve cone, valve seat, valve housing and valve rubber; The inner side activity of valve housing arranges valve seat, arranges valve rubber between valve seat and valve housing, and the below of valve rubber arranges hydrovalve rubber extruding device.The utility model extrudes height by controlling injection liquid scale of construction control valve rubber from upper end, with the wearing part before compensating.Compared with prior art, cost lower, safeguard more convenient.
Description
Technical field
The utility model relates to a kind of one-way valve, particularly relates to a kind of hydraulic pressure valve rubber compensation type one-way valve being convenient to safeguard.
Background technique
In recent years, based on the larger fluid conveying equipment of diaphragm pump, mortar pump, slurry pump, in promotion and application in industrial automation, development is rapidly, especially at alumina factory apparatus for production line, and mill tailings conveying equipment, in the remote granule fluid transportation art such as water coal slurry conveying equipment, served very important key effect, and one-way valve is in these conveying equipment for fluid substances, changes spare part the most frequent, operating cost is the highest, is also one of the most anxious parts to be modified.Up to the present, except the acquired patent of claimant " valve rubber compensation type one-way valve " (patent No. is 201110161639.4) and " gear promotion valve rubber compensation type one-way valve " (patent No. is 201220673281.3), under there is no the prerequisite possessing the every using function of existing one-way valve at the same time, can also significantly reduce parts replacement frequency, reduce the better product of operating cost.But in actual applications, user cost is relatively high for valve rubber compensation type one-way valve (patent No. is 201110161639.4) and " gear promotion valve rubber compensation type one-way valve " (patent No. is 201220673281.3), safeguard inconvenience relatively.
Model utility content
The utility model, for above-mentioned present situation, through carefulness development and repetition test, is designed a kind of hydraulic pressure valve rubber compensation type one-way valve, is solved cost in prior art high, safeguards the problem of inconvenience.
The technical solution of the utility model is as follows:
Comprise valve gap, guide sleeve, hydrovalve rubber extruding device, valve cone, valve housing and valve rubber; The inner chamber activity of valve housing arranges valve seat; The outer face, garden of taper on valve seat contacts with face, garden in the taper of valve housing inner chamber and coordinates, and be provided with valve seat insert and oil groove between surface of contact, the oil inlet hole of oil groove leads to the jack-up valve seat pouring orifice of valve housing outer wall; Cylindrical outer surface on valve seat and between valve housing inwall, valve rubber is set; The below of valve rubber arranges hydrovalve rubber extruding device, and hydrovalve rubber extruding device is made up of oil pocket and jack-up valve rubber pouring orifice, and oil pocket is communicated with by oilhole with jack-up valve rubber pouring orifice; Valve cone is pressed on valve rubber by valve spring; Described valve cone controls its track moved up and down by guide sleeve.
The bottom activity of described valve gap arranges valve gap liner plate.
Described valve rubber is arranged the rigidity base plate connected together, base plate arranges seal groove.
The fluting of described valve seat insert and oil groove are opened on the conical external circle face of valve seat or to be opened in the taper of valve housing inner chamber on face, garden.
The utility model has the advantages of as follows:
1, be provided with the valve seat of replacing for convenience detach in one-way valve inside, when valve seat is worn to when can not normally use, replacing spare part can be pulled down.
2, when valve rubber weares and teares or other reasons is damaged, according to the order of severity of wearing and tearing or damage, when needs recuperation valve rubber, utilize hydrovalve rubber extruding device, accurately valve rubber can be extruded one section by predetermined backoff amount, with the broken parts before compensation, avoid valve cone and valve seat to bump against, guarantee that one-way valve normally works.
3, low cost of manufacture, operating cost is low, safeguards simpler, more convenient.
