Abstract

An instant drinking machine double-floater intake valve that can control over-high water pressure comprises a lower floater, a lower valve rod, a gasket, a lower valve core, a valve body, an opening pin and a valve cover, a shaft pin, an upper valve rod, an upper valve core, a valve body, an upper floater, an fixing bolt, a water bucket that are arranged on the upper end of the valve body in order. When water flow of normal pressure is imported and the water capacity of the water bucket is reached, the buoyancy lever action of the lower floater will push the valve core tightly against the water outlet hole end of the valve body to stop water import. When water pressure is too high and the valve core is pushed open in the opposite direction, water level in the water bucket will rise with continuous water import. Then, the upper floater will produce buoyancy and lever action, and the upper valve core will press against the water inlet hole to cut water flowing.

Description

The two float inlet valves of straight drink machine

Technical field

The utility model relates to a kind of drinking machine inlet valve, controls the inlet valve of water inlet especially for two floats of straight drink machine.

Background technique

Single float inlet valve of the straight drink machine that provides in the market is made up of valve seat, valve body, spool, valve rod, pivot pin, float, steel ladle.After entering steel ladle from the feed-water end of valve body through the water purification after the filtration of high-pressure water pump input, along with the water level in the steel ladle increases, float on the valve body is also along with buoyancy during to the water purification capacity set, because under the leverage of buoyancy and valve rod, promote spool, spool is withstood the water inlet on the valve body and stop into water.Because the water purification after filtering enters steel ladle after pressurizeing through the high pressure feed-water pump.But too high because of intake pressure sometimes, surpass spool oppositely being pushed open of float to buoyancy, make inflow uncontrollable and cause steel ladle water excessive.

Summary of the invention

The purpose of this utility model provides the two float inlet valves of a kind of straight drink machine, two up and down floats on the valve body can be controlled the high pressure feed-water pump and import the water capacity that the water source of normal pressure enters steel ladle, and upward float can prevent that the high pressure feed-water pump from occurring will descending when unexpected too high water delivery pressure is imported steel ladle with water the spool in the float-controlled valve to push the unexpected spilling water phenomenon of generation open

The purpose of this utility model is achieved in that in the lower end of valve body by float down, lower valve rod, packing ring, lower valve core, valve body, cotter pin, be linked in sequence and form valve down, in the valve body upper end valve on is set in addition, by valve gap, pivot pin, upper valve rod, upper valve core, valve body, last float, the set screw steel ladle composition that is linked in sequence, when being normal pressure by high pressure feed-water pump input water purification, because the float height and the capacity that is filled with water that steel ladle is set in advance, the lower valve rod that is connected with float is under the effect of leverage, lower valve core is upwards promoted to hold out against valve body osculum lower end and stop into water, if during the water purification pressure overshoot pressure criteria of high pressure feed-water pump input, the buoyancy that lower valve core in the valve body is subjected to the compression shock of high pressure water inlet to overcome float continues water inlet, when at this moment water inlet reaches setting height, the last float that the steel ladle water level increases on the valve body produces floating function, and the same because leverage of upper valve rod on valve body depressed the cutoff high water source, water inlet that withstands on the valve body with upper valve core and reached application target.

Owing to adopted such scheme, can on straight drink machine, use the water source of normal pressure to enter steel ladle, the water capacity in the control steel ladle also can enter steel ladle at the abnormal pressure water source, and keeps the normal water capacity in the steel ladle to make water not excessive.

Embodiment

Lower valve rod among Fig. 2 (8) and packing ring (9), spool (10) is linked in sequence, after the combination spool (10) packed in the following stomidium of valve body (5) and to connect the valve under float (17) is formed down of packing into cotter pin (11), then valve gap (1) upper valve rod (3) of packing into is inserted in the mounting hole that upper valve core (4) inserts valve body (5) of packing into behind the pivot pin (2), and with set screw (6), (7) upward valve is formed in fastening float (16) back of loading onto, then two float inlet valves integral body are connected and fixed with set screw (13) (14) with valve seat (12) installation place, load onto steel ladle (15) and can realize the utility model.
