Abstract

The utility model relates to a semiautomatic constant-weight water supply valve and a manual valve. The utility model belongs to valves. The utility model is designed in view of a situation that the timing water-supply is used in unmanned families. The utility model comprises a meter, a transmission rod and a valve body. A valve rod and a closing rod are arranged on the valve body. After the valve rod is pressed, the valve rod is blocked by a transmitted end head. The valve rod can not fall down. The valve is positioned in an open state. When the water supplying quantity reaches to the fixed value, a connection movement rod impacts the transmission rod. The end head of the transmission rod is back out from gaps. The valve rod falls down, and the valve is closed. The closing rod can close the valve at any time. The utility model can supply the water at the fixed quantity. The utility model has the advantages of convenient installation and operation.

Description

Semiautomatic constant-weight water supply valve and manual valve

The utility model belongs to valve.

Because China's water resources is relatively more nervous, Timing water supply is carried out to the resident in present many cities, and therefore, many families all have tank.Do not have in family idler's the family, the device that nobody also can water receiving in a kind of family is a utmost point needs.Existing this device is a float lever formula valve, and this device can be automatically with valve closing when the container filled with water.This device or position, the shape of container had certain requirement maybe will be changed water supply line, installs very inconveniently, and there is the shortcoming that is not closed completely, easily leaks in the float type valve, and is difficult to accept for vast family.

It is a kind of easy for installation that the purpose of this utility model is to provide, to the position of water container, shape without limits can quantitative water supply semi-automatic quantitative water supply valve.

The utility model is realized by technological scheme shown in the drawings.It is made up of metering mechanism and valve body two-part, metering mechanism is by impeller 1, multistage driving gear set 3 constitutes, on the axle of the final stage gear 4 of driving gear set, fix one and semi-convexly take turns 11, both are coaxial, the semi-convex wheel presses closer a L shaped continuous motion stem 10, in metering mechanism, also has a L shaped drive link 7, the cross bar of drive link contacts with valve rod 9 and pole shutoff 14 on the valve body, the upper surface of cross bar is the inclined-plane, the montant tail end bending of drive link, become a point of action, continuous motion stem can impinge upon on the point of action, thereby make the drive link action,

spring

12 and 13 are arranged on drive link and the continuous motion stem, valve rod and drive link cross bar contact segment have the right angle gap, and the cross bar contact segment of pole shutoff and drive link has an inverted gore 8, is fixed with a spring sheet 6 on the valve rod, its termination is below the final stage gear, and the spool of valve rod upwards pushes up down a spring.

During the utility model work, press lower valve rod, valve rod is stopped and can not rebound at opening position by the bar of L shaped drive link is horizontal, valve is opened, under the effect of current, wheel rotation, driven gear group slow rotation is on the final stage gear shaft, the semi-convex wheel obtains a bigger moment of torsion, thereby with continuous motion stem jack-up slowly, when the flow of water reached certain certain value, the semi-convex wheel with the maximum radius place contacted with continuous motion stem, semi-convex take turns continuous motion stem backed down ultimate range after, the semi-convex radius of taking turns is suddenly for minimum, and this moment, continuous motion stem was rebounded under the effect of spring at once, impinged upon on the point of action of drive link, drive link moves backward, the cross bar of drive link is taken out of from the gap of valve rod, and valve rod is upspring, and spool seals water channel.Simultaneously, under the effect of spring sheet, final stage gear and gear train are separated, and finish a quantitative water supply process.If think throttle down at any time, as long as click pole shutoff, the inverted triangle of pole shutoff squeezes the cross bar that pushes away drive link, makes it to be pushed out from the gap of valve rod, thereby valve rod is upspring, valve closing.

The technological scheme of the utility model valve body part can be used for single manually-operated gate, removes metering section, is made of valve rod, pole shutoff and L shaped drive link (can claim throw-out lever at this) to get final product.See accompanying drawing 4.

Be embedded with the knob 5 of a band scale on the axle of final stage gear, turning knob can be determined semi-convex the wheel at an arbitrary position, thereby can determine each water output arbitrarily in the maximum water output scope of valve.The definite of the maximum water output of valve can recently realize by area and the gear of adjusting impeller.

The semi-automatic quantitative water supply valve that the utility model provides rational in infrastructure, compact, control is reliable, can be directly installed on the water supply line, and only need connect a sebific duct between water container and get final product, and uses very convenient.Because water output is adjustable, the user needn't worry the container spilling water, and structure of the present utility model can also be used for other liquid, as oils, drinks.The manually-operated gate that the utility model provides, spool are taked the upwards closed form of sealing, by the hydraulic pressure throttle down, hydraulic pressure is big more close tight more, thereby solved the problem of leaking when valve hydraulic pressure is big in the past.

Accompanying drawing 2 is the semi-automatic quantitative water supply valve of a utility model plan view;

Accompanying drawing 3 is accompanying drawing 1 right elevation;

Accompanying drawing 4 is the utility model manually-operated gate positive view.

Embodiment

As shown in Figure 1, gear is than for 10:1, and the number of gears is 5, and the blade of impeller is that round diameter is 10 millimeters, and it is 0.5 millimeter hole 2 that there is diameter at the blade center, and maximum water output is 60 kilograms.Metering mechanism is arranged on the waterexit end of valve body, thereby has avoided metering mechanism to leak and be immersed in water.

Claims
