Abstract

The invention discloses a floating ball valve for controlling a water level by draining water, comprising a valve body with a valve, a valve core and a valve rod, wherein one end of the valve rod is articulated to the valve body, and the other end of the valve rod is connected with a floating ball. The floating ball valve is characterized in that the valve body below the valve is a tubular object with an installation stop surface and outer threads, the valve body above the valve is in a cylindrical shape, two grooves which are machined along the axial line are arranged on the side wall of the tubular valve body and are parallel to the axial line, a connecting line of centers of mouths of the two grooves passes through the axis of the tubular valve body, two parallel lugs are arranged on the side wall of the tubular valve body arranged at two sides of the outer side of one groove, one end of the valve rod is articulated between the two parallel lugs, the valve core comprises a valve core body, a sealing washer arranged below the valve core body and a fork type object arranged on the valve core body, and part of the valve rod arranged in the tubular valve body is articulated into a fork of the fork type object. Compared with the prior art, the floating ball valve has the advantages that the structure is simple, components of other processes (such as the patent CN200910038313.5) can be commonly used in the floating ball valve, and the manufacture cost is low.

Description

A kind of by the float valve of draining control water level

Technical field

The present invention relates to a kind of valve.

Background technique

Existing float valve is all generally the amount of carrying out control valve water inlet by the buoyancy of ball float, as patent, CN200910038313.5 is disclosed, and in the time that the water level in pond is less than designated water level, valve is opened in pond and supplied water, in the time that water level reaches predetermined water level, the ball float floating is closed valve.In actual using process, need to keep water level in water pool by the water in discharge pond, like this, just need to use the patent CN200910039009.2 as the inventor invented, limited by the technology of this patent, this technology one is carried out complex structure, manufacture cost is high, and two, the member of this patent can not be general with the member of other technologies (as patent CN200910038313.5), like this, also increase the cost that this technology is implemented.

Summary of the invention

Goal of the invention of the present invention is to provide a kind of float valve that passes through draining control water level member, low cost of manufacture simple in structure, can general other technologies (as patent CN200910038313.5).

The present invention realizes like this, comprise and be with valvular valve body, spool, wherein one end is hinged on valve body and the other end is connected with the valve rod of ball float, its specialization is that the valve body below valve is with only face and externally threaded pipe are installed, valve body above valve is socket shape, the sidewall of socket shape valve body is provided with two grooves that break along axis, two grooves are parallel with axis, the line at the center of the notch of two grooves is through the axis of socket shape valve body, on the sidewall of the socket shape valve body on the both sides, outside of a groove, be provided with two parallel projections therein, wherein one end of valve rod is hinged between two parallel projections, spool comprises valve core, be arranged on the seal rubber pad below valve core, be arranged on the fork above valve core, the part valve rod that is positioned at socket shape valve body is hinged on the fork of fork.When use, the present invention is installed to the nut that stops face and be screwed on male-pipe by it to be fixed in sink waste, make tubular valve body above valve of the present invention upwards, according to the position of water level settings ball float, like this, when water level in water pool is during lower than designated water level, under the effect of float valve deadweight, valve rod band movable valve plug moves down, and spool is covered with valve valve is sealed, by valve closing, water just can not be discharged outside pond; When water level is during higher than designated water level, on the ball float band ovable valve stem floating, move, valve rod is with on movable valve plug and is moved away valve, valve open, pond just can draining, until water level returns to designated water level.

The present invention is owing to being on the basis of patent CN200910038313.5 technology, the structure of valve rod and the annexation with valve body thereof are simplified, increase valve rod and the hinged artificer of spool are used instead original drain opening do water intake, original water intake is used instead and done drain opening, therefore, have advantages of members simple in structure, can general other technologies (as patent CN200910038313.5), low cost of manufacture.

Brief description of the drawings:

Fig. 1 is structural representation of the present invention;

Fig. 2 be the B of Fig. 1 order possess enlarged view.

Embodiment:

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:

As shown in the figure, the present invention includes the circular-arc valve body 2 of 90 degree with valve 1, spool 3, wherein one end 4a is hinged on valve body 2 and the other end 4b is connected with the valve rod 4 of ball float 5, on valve 1, be provided with bulge loop 6, its specialization is that valve 1 valve body 2a is below the pipe that stops face 2b and outside thread 2c and be screwed in the nut 2d on outside thread 2c with installing, valve 1 valve body 2d is above socket shape, the sidewall of socket shape valve body 2d is provided with two grooves 7 that break along axis A, 8, two grooves 7, 8 is parallel with axis A, two grooves 7, the line at the center of 8 notch is through the axis A of socket shape valve body 2d, on the sidewall of the socket shape valve body 2d on the both sides, outside of a groove 8, be provided with two parallel projections 9 therein, wherein one end 4a of valve rod 4 is hinged on 9 of two parallel projections by being connected to the axle 11 of 9 of two parallel projections, spool 3 comprises valve core 3a, be fixed on the seal rubber pad 3b below valve core 3a, be connected to the fork 3c above valve core 3a, two couples of symmetrical montant 3c1 before and after fork 3c comprises, be separately fixed at two couples of two boards 3c2 on montant 3c1, the part valve rod 4c that is positioned at socket shape valve body 2d by be connected to axle 10 between two boards 3c2 be hinged on fork 3c by montant 3c1, in the fork 3c3 that plate 3c2 forms.

Here, being positioned at the hole 12 that the axle 10 on the part valve rod 4c of socket shape valve body 2d passes is horizontal concrete chute, the Outside Dimensions that the two couples of symmetrical montant 3c1 form and the internal diameter of socket shape valve body 2d match, like this, under the leading role of two couples of symmetrical montant 3c1, ensure that spool 3 faces valve 2 and moves, and the effect of horizontal concrete chute 12 is positions of automatic regulating valve bar 4 and spool 3, ensures that valve rod 4 supports smoothly band movable valve plug 3 and moves.
