The problem of current drain tap structure is complicated, and the maintenance cost is high, techniques such as life weak point is solved, the structure includes valve body, diaphragm, flange, diaphragm pressing cover, and the valve body both sides are equipped with the air inlet, and the gas vent is equipped with flange in the air inlet, be equipped with gas storage chamber and exhaust chamber in the valve body, the intake duct intercommunication at gas storage chamber and flange middle part, valve body upper portion is for opening wide the structure, is equipped with diaphragm pressing cover on valve body upper portion, the last control gas circuit interface that is equipped with of diaphragm pressing cover is equipped with the diaphragm between diaphragm pressing cover and valve body. The utility model relates to a simply, rational in infrastructure, the maintenance cost is low, the reliable operation.
Description
Technical field
The utility model relates to a kind of valve, is specially a kind of gas control outlet valve.
Background technique
Outlet valve is very important parts for the core machine of casting field.Its function is the on-off function realizing device interior gas circuit, and for meeting the requirement of obstructed air displacement, specification has DN20 to DN150 to customer selecting, and the species structure of outlet valve is various, and preparation process is different, and internal structure is different.Identical is the inner diaphragm all having partition air inlet and air outlet, and this diaphragm is easily damaged parts.
The outlet valve of commercial type, takes up room large, cannot meet the compact type requirement of equipment de-sign.Maintenance cost is high, and inner rubber diaphragm needs to use import rubber product, for DN80 outlet valve, each elastomer diaphragm needs 1300 yuan.The diaphragm life-span is short, and average use 20000 times, diaphragm just deforms, and cannot use.
The outlet valve product that such as U.S. meter Dun Luo company produces.This product can realize break-make about 60000 times/year, and inner rubber sleeve is namely damaged, needs to change.For core machine, on average change 1 rubber sleeve about every year, changing rubber sleeve wastes time and energy, and needs 2 people cooperating simultaneously, has changed needs 1 hour, reinstall on equipment and separately need 1 hour.Maintenance cost is high, and for DN80 outlet valve, each rubber sleeve needs 2500 yuan.The price of a whole set of outlet valve needs 5500 yuan.
Summary of the invention
The utility model is in order to solve existing drain tap complex structure, and the technical problems such as maintenance cost is high, and working life is short, provide a kind of gas control outlet valve.
The technical solution of the utility model is, a kind of gas control outlet valve, and structure comprises valve body, diaphragm, adpting flange, diaphragm gland, and valve body both sides are provided with suction port, and relief opening is provided with adpting flange in suction port; Air storing cavity and exhaust cavity is provided with in valve body, described air storing cavity is communicated with the intake duct in the middle part of adpting flange, and valve body top is open design, is provided with diaphragm gland on valve body top, pressing diaphragm covers and is provided with control air-path interface, between diaphragm gland and valve body, be provided with diaphragm.
Outlet valve described in the utility model, straight-through type air inlet is adopted to give vent to anger, UNICOM between intake duct and relief opening, controlled by the distortion of diaphragm, in time not needing exhaust, control air-path interface air inlet, produce pressure and diaphragm is bent downwardly, diaphragm closes air storing cavity, then not conducting between exhaust cavity and intake duct; When needing exhaust, control air-path interface release gas pressure, diaphragm resilience, air storing cavity upper end and exhaust cavity UNICOM, such gas just can be discharged, and realizes degassing function.
Be bolted between described diaphragm pressing plate and valve body, such structure makes the position of diaphragm be convenient for changing, if diaphragm occurs damaged, removes four bolts of gland, changes diaphragm.
Described intake duct and exhaust ports, in same axis, adopt straight-through type air inlet to give vent to anger, and by improving outlet valve internal structure, solve air inlet and give vent to anger in the problem in 90 ° of directions, gas is discharged from outside after inner air flue turns round through import again.Controlling gas circuit design makes whole outlet valve for making whole exhaust structure compact in side,
The overall structure of this outlet valve is processed by steel part, welding production forms, 10 years working life.The structural design of inner sealing, can use the balata belt of 6mm to 10mm to replace, with low cost.If the annual break-make frequency is higher, can the good silicane rubber plate of using character etc., cost about 100 yuan/sheet.
Apparatus structure described in the utility model is compact, and applicability is high.This outlet valve is different from other outlet valves, is workpiece, can change length, facilitate the design and installation of equipment according to the obstructed requirement of equipment.The size of inlet end, outlet side and Placement can meet the requirement of obstructed equipment.
This convenience for device maintenance, time saving and energy saving.The diaphragm of example exhaust valve occurs damaged, and one has got final product replacing diaphragm for personal 20 minutes or checked the work of diaphragm.Inner diaphragm can use balata belt or silicane rubber plate, and annual maintenance cost is about 10 yuan to 100 yuan.
This device is cost-saving, uses reliable.This outlet valve uses steel part processing, welding system forms, and uses lathe, drilling machine, welding machine can complete the processing and fabricating of this product.
