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 float valve through the draining control water level

Technical field

The present invention relates to a kind of valve.

Background technique

Existing float valve generally all is the amount of coming the control valve water inlet through the buoyancy of ball float; CN200910038313.5 is disclosed like patent, and when the water level in pond during less than designated water level, valve is opened in the pond and supplied water; When water level reached predetermined water level, the ball float that floats was closed valve.Need keep water level in water pool through the water in the discharging pond in the actual using process, like this, just need to use patent CN200910039009.2 as the inventor invented; Limited by the technology of this patent; This technology one is come complex structure, manufacture cost height, and two, the member of this patent can not be general with the member of other technologies (like patent CN200910038313.5); Like this, also increased the cost of this technology implementation.

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, the general other technologies of ability (like patent CN200910038313.5).

The present invention realizes like this; Comprise the valve body that has valve, spool, wherein an end is hinged on the valve body and the other end is connected with the valve rod of ball float; Its specialization is that the valve body below the valve is to have to install to end face and externally threaded pipe, and the valve body above the valve is the socket shape, and the sidewall of socket shape valve body is provided with two grooves that break along axis; Two grooves and parallel axes; The line at the center of the notch of two grooves is through the axis of socket shape valve body, and the sidewall of the socket shape valve body on the both sides, the outside of a groove is provided with two parallel projections therein, and a wherein end of valve rod is hinged between two parallel projections; Spool comprises valve core, be arranged on seal rubber pad below the valve core, be arranged on the fork above the valve core, and that part of valve rod that is positioned at socket shape valve body is hinged on the fork of fork.During use, the present invention is installed the nut that ends face and be screwed on the male-pipe through it be fixed on the sink waste, the tubular valve body above the valve of the present invention is made progress; According to the position of water level settings ball float, like this, when water level in water pool is lower than designated water level; Under the effect of float valve deadweight, valve rod drives spool and moves down, and spool is covered with valve valve is sealed; With valve closing, water just can not be discharged outside the pond; When water level was higher than designated water level, the ball float that floats drove on the valve rod and moves, and valve rod then drives and moves away valve on the spool, valve open, and just ability draining of pond is till water level returns to designated water level.

The present invention is owing to be on the basis of patent CN200910038313.5 technology; Simplified valve rod structure and with the annexation of valve body; Increased valve rod and the hinged artificer of spool used instead original drain opening and done water intake; Original water intake used instead do drain opening, therefore, have simple in structure, members that can general other technologies (like patent CN200910038313.5), advantage of low manufacturing cost.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 possesses enlarged view for what the B of Fig. 1 was ordered.

Embodiment:

Combine accompanying drawing and embodiment that the present invention is done describes in further detail at present:

As shown in the figure; The present invention includes the circular-arc valve body of 90 degree 2 that has valve 1, spool 3, wherein an end 4a is hinged on the valve body 2 and the other end 4b is connected with the valve rod 4 of ball float 5; Valve 1 is provided with bulge loop 6; Its specialization is that the valve body 2a below the valve 1 has the pipe that ends face 2b and outside thread 2c and be screwed in the nut 2d on the outside thread 2c is installed; Valve body 2d above the valve 1 is the socket shape; The sidewall of socket shape valve body 2d is provided with two

grooves

7,8 that break along axis A; Two

grooves

7,8 are parallel with axis A, and the line at the center of the notch of two

grooves

7,8 is through the axis A of socket shape valve body 2d, and the sidewall of the socket shape valve body 2d on the both sides, the outside of a groove 8 is provided with two parallel projections 9 therein; A wherein end 4a of valve rod 4 is hinged on 9 of two parallel projections through the axle 11 that is connected 9 of two parallel projections; Spool 3 comprises valve core 3a, be fixed on seal rubber pad 3b below the valve core 3a, be connected the fork 3c above the valve core 3a, the montant 3c1 of two pairs of symmetries before and after fork 3c comprises, is separately fixed at two couples of two boards 3c2 on the montant 3c1, and that part of valve rod 4c that is positioned at socket shape valve body 2d is hinged on the fork 3c3 that is made up of montant 3c1, plate 3c2 of fork 3c through being connected spools 10 between two boards 3c2.
