Abstract

The utility model relates to a bottom valve, which is used in a water sucking pipeline, particularly an overwater horizontal bottom valve. The utility model is composed of a valve body, a valve cover, a valve plate, a swinging rod, etc. The utility model is mainly characterized in that in a water inlet pipe on one end of the valve body, the valve plate arranged on a port in a valve body is lifted up and is opened by taking the swinging rod as the radius and a supporting lug on one end of the swinging rod connected with the inner wall of the valve body via pins as the center. In the utility model, the present situation that a bottom valve is installed on a vertical pipeline which extends into water and on the tail end of a pump suction pipe is changed; the bottom valve is directly installed in a suction pipeline above a water surface. The water suction resistance is little, and the maintenance is convenient.

Description

Horizontal foot valve

The utility model relates to a kind of bottom valve that uses on the suction piping, relates in particular to horizontal foot valve.

Existing bottom valve, or claim Vertical Lift Check Valves, the suction pipe end that is installed in water pump gos deep in the water, and requires to be installed on the vertical pipe.Its structure is: valve body divides two-part up and down, and is connected by bolt, and level is to being equipped with valve plate in the following valve body, the central hinged bivalve flap of valve plate, during work, flap is that the center is lifted and passed through current with the articulating point, this bottom valve suction resistance is bigger, in case the maintenance difficulty that breaks down.

The purpose of this utility model is to overcome the deficiency that above-mentioned bottom valve exists, provide a kind of can be installed on the water surface, the suction resistance is little, install and overhaul horizontal foot valve easily.

The purpose of this utility model is achieved through the following technical solutions: a kind of horizontal foot valve, it is characterized in that being welded with flange on the water inlet and outlet mouth of pipe at valve body two ends, level between the water inlet and outlet mouth of pipe is to the valve body upper shed, be added with sealing gasket and valve gap on mouthful, between valve gap and the valve body through bolt, intake pipe becomes angle to prolong with valve body wall in valve body, welding seat on the port of pipe, be stamped valve plate on the valve seat, sealing gasket between valve plate and the valve seat is through fastening valve plate and being bolted on the valve plate, fixing rocking bar on the fixing support pad in the valve plate outside, an end of rocking bar links through bearing pin with the support pad that is fixed on valve interior wall.

The utility model is fixed on the pipeline on the above bank of the water surface, during work, valve plate in the valve body is radius with the rocking bar, the support pad of valve interior wall pin joint rocking bar one end is carried in the heart in being and being opened, adopt the utility model, need not to establish again vacuum pump, suction pipe is not less than 3-5 doubly by water pump to the length of pipe section between the bottom valve than bottom valve to suction pipe tip length, before the turn on pump pump upper air-vent is opened, with the suction pipe fills with water, and close exhaust port, starting rapidly then, by the last period the pipe capacity cause suction pipe partial vacuum state, thereby reach suction work, can normally move for reciprocal 2-3 time by this method.

Accompanying drawing is the utility model structural representation;

In the accompanying drawing: the 1st, valve gap, the 2nd, sealing gasket, the 3rd, bolt, the 4th, valve body, the 5th, rocking bar, the 6th, bearing pin, the 7th, valve plate, the 8th, sealing gasket, the 9th, fastening valve plate, the 10th, valve seat, the 11st, flange;

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by valve body 4, valve gap 1, valve plate 7, rocking bar 5 formations such as grade, valve body 4 is square, both sides are welded intake pipe and outlet pipe respectively, turnover water pipe is not on same center line, the center line of outlet pipe is higher than the center line of intake pipe, all be welded with flange 11 on the water inlet and outlet mouth of pipe, level to valve body 4 on have mouth, be added with sealing gasket 2 and valve gap 1 on mouthful, valve gap 1 is fixed on the valve body 4 through bolt 3, and intake pipe becomes angle to prolong with valve body wall in valve body 4, the opening of the mouth of pipe on valve body 4, welding seat 10 on the mouth of pipe, and valve plate 7 is set on the valve seat 10, and there is fastening valve plate 9 in sealing gasket 8 outsides on the valve plate 7, the hole that bolt passes on the fastening valve plate 9 is screwed in the tapped hole of valve plate 7, with fastening valve plate 9, sealing gasket 8 and valve plate 7 are solidified as a whole.The outside of valve plate 7 is fixed with support pad, fixing rocking bar 5 on the support pad, and an end of rocking bar 5 links through bearing pin 6 and support pad on valve body 4 inwalls.

Claims
