Description
Technical field
The utility model relates to a kind of auxiliary facility of self-hardening sand continuous muller, particularly is used for controlling the gas control fluid feed valve of liquid material in a kind of above-mentioned sand muller liquid feeding system.
Background technique
In the self-hardening sand continuous muller liquid feeding system, conventional method is with resin and curing agent, directly adds mulling with gear pump and diaphragm pump through pipeline respectively and stirs cage assembly.The disadvantage of this method is when opening the mulling of self-hardening sand continuous muller at every turn, accurate control head sand, be sand muller when just having started in the pipeline resin and curing agent flow discontinuous unstable, make sand and resin, curing agent mix inhomogeneous sand, can not normally use, a sand must be reclaimed again and repeatedly carry out mulling and could use, cause the wasting of resources; And self-hardening sand continuous muller liquid feeding system can't realize automatic control, increased manipulation strength, reduced productivity.
Summary of the invention
Task of the present utility model is to solve the problem that above-mentioned prior art exists, and a kind of gas control fluid feed valve is provided, and can make liquid feeding system realize automatically control in order to accurate control head sand, reduces the wasting of resources, boosts productivity.
The utility model technological scheme that adopts of dealing with problems is:
This gas control fluid feed valve comprises left end cap, left barrier film, valve body, right barrier film, right end cap.Described valve body is provided with left and right sides through hole and left blind hole, right blind hole, be provided with intake port, discharge hole and back material hole on other side, described left and right sides through hole is communicated with intake port, described left blind hole, right blind hole are communicated with discharge hole and back material hole or back material hole and discharge hole respectively, described left end cap is provided with suction port, left end cap is fixed on the left end of valve body with left barrier film, and described right end cap is provided with suction port, and right end cap is fixed on right barrier film the right-hand member of valve body.
The preferred version of technique scheme is as follows:
Described valve body is provided with left and right sides central through bore and left and right centrosymmetric blind hole, described central through bore is communicated with intake port, left and right centrosymmetric blind hole is communicated with discharge hole and back material hole or back material hole and discharge hole respectively, left end cap is provided with the suction port corresponding with central through bore, and right end cap is provided with the suction port corresponding with central through bore.
This gas control fluid feed valve is fixed on the sand muller mulling and stirs on the cage assembly shell.
The working principle of this gas control fluid feed valve: the gas control fluid feed valve is connected with diaphragm pump with gear pump respectively, and the curing agent flow that the resin that will be extracted out by gear pump and diaphragm pump are extracted out keeps continous-stable, thereby guarantees the mixed qualified molding sand of making.When opening the mulling of self-hardening sand continuous muller when stirring cage and beginning mulling, the right end cap ventilation of gas control fluid feed valve, the discharge hole that is communicated with right blind hole on the right barrier film valve body, left end cap is died simultaneously, left barrier film is opened the back material hole that is communicated with left blind hole on the valve body, liquid material is entered by the intake port on the valve body, the left and right sides through hole on the valve body of flowing through, left blind hole from back material hole in pipeline flows back to storage vat; Through a few circulations in second, behind the interior liquid material flow continous-stable of pipeline, right end cap is died, right barrier film is opened the discharge hole that is communicated with right blind hole on the valve body, simultaneously left end cap ventilation, the back material hole that is communicated with left blind hole on the left barrier film valve body, liquid material left and right sides through hole, right blind hole and the discharge hole on valve body enters mulling and stirs the qualified molding sand of cage and the sand system of mixing.
The beneficial effects of the utility model are used accurately control head chiltern amount of this gas control fluid feed valve, avoid a sand again to reclaim repeatedly mulling, have saved cost, have reduced the wasting of resources; Make self-hardening sand continuous muller liquid feeding system realize automatically control, save time, can greatly boost productivity.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Accompanying drawing is the organigram of gas control fluid feed valve.
Embodiment
As shown in the figure, this gas control fluid feed valve comprises left end cap 1, left barrier film 2, valve body 3, right barrier film 4, right end cap 5.Valve body 3 is provided with left and right sides central through bore 3d and centrosymmetric left blind hole 3e, right blind hole 3f, and downside is provided with intake port 3a and back material hole 3b, and upper side is provided with discharge hole 3c; Central through bore 3d is communicated with intake port 3a, and left blind hole 3e is communicated with back material hole 3b, and right blind hole 3f is communicated with discharge hole 3c; Left end cap 1 is provided with suction port 1a, and left end cap 1 is screwed left end at valve body 3 with left barrier film 2, and right end cap 5 is provided with suction port 5a, and right end cap 5 is screwed right-hand member at valve body 3 with right barrier film 4.
This gas control fluid feed valve adopts gas control fluid feed valve support to be fixed on the sand muller mulling and stirs on the cage assembly shell.
