Abstract

A water hammer pump, comprising a T-tube, a curved pipe, a fitting tube and a drain valve seat made of cast iron, can reduce weight of the pump body. What is more important is that the force onto the drain valve, caused by powerful water-striking when draining port is shut suddenly, can be transmitted into earth through the drain valve seat made of cast iron, in order to avoid and lower damage to the drain valve because of powerful water striking phenomenon.

Description

Water attack lift pump with pipe fitting and cast iron seat formation

Technical field

The utility model belongs to water attack lift pump field, particularly relates to the water attack lift pump that constitutes with pipe fitting and cast iron seat.

Background technique

Recently, the water attack lift pump that Zhejiang Province's Lishui City is introduced from Germany, the water attack lift pump of similar China sixties in last century, this pump structure is simple, but very heavy, particularly emptying valve is often broken up by water hammer, is that China is difficult to one of reason of promoting the use of by the water attack lift pump.

Summary of the invention

The purpose of this utility model is: provide a kind of and constitute novel water attack lift pump with three-way pipe, bend pipe, CONCENTRIC REDUCER pipe and the drain valve gate seat cylinder iron made, can overcome above-mentioned deficiency.

After the purpose of this utility model is achieved in that CONCENTRIC REDUCER pipe, three-way pipe, bend pipe is welded successively, mix and intake pipe, the drain valve gate seat of cylinder iron making and the corresponding flange of gas holder at three ports, pack into drain valve and setting-out valve, connect with bolt again.

Adopting this scheme to pump up water with existing water attack compares: the weight that can not only alleviate pump, importantly when drain valve in moment that discharge opening is closed suddenly, the active force of the powerful water hammer that produces in the water attack lift pump, can be delivered to by the drain valve gate seat of cylinder iron making underground, thereby avoid or alleviate the destruction of the active force of powerful water hammer emptying valve.

The utility model is to constitute like this: with CONCENTRIC REDUCER pipe (2), three-way pipe (3), bend pipe (8), successively after the welding, portlet in CONCENTRIC REDUCER pipe (2), the middle port of three-way pipe (3), the port of bend pipe (8), welding is gone up and intake pipe (1) again, the corresponding flange (15) of drain valve gate seat of cylinder iron making (4) and gas holder (12), flange (16) and flange (14), promptly constitute the pump housing of water attack lift pump, reinstall drain valve (7) and setting-out valve (9), use bolt (17) to connect the drain valve gate seat of cylinder iron making (4) at last, gas holder (12) promptly constitutes water attack lift pump of the present utility model.

During use, the water attack lift pump being fixed on the ground (6) with stone bolt (5), using bolt (17) to connect intake pipe (1) and lifting pipe (10) again, is exactly the complete water attack lift pump device of a cover.

Description of drawings

Schematic representation when Fig. 1 is structure of the present utility model and work.

Embodiment

1 pair of the utility model further describes in conjunction with the accompanying drawings.

The water attack lift pump is like this work: when water from the high drop of H, rapidly from intake pipe (1) pump housing of flowing through, during discharge opening (18) by the interior lower end of drain valve gate seat (4) of cylinder iron making, drain valve (7) cuts out discharge opening (18) suddenly, because current action of inertia, in the pump housing and the drain valve gate seat (4) cylinder iron made, can produce powerful water hammer, the pressure of water is sharply raise, under the effect of high pressure water, setting-out valve (9) is open, the part high pressure water enters gas holder (12), and makes the air in the gas holder (12) form pressurized air (11).But most of high pressure water comes not anxious in the pump housing, also can not all enter gas holder (12), can only flow backwards to the high water source direction of H along intake pipe (1), because refluence water action of inertia, moment produces negative pressure again in the pump housing and the drain valve gate seat (4) cylinder iron made.At this moment, setting-out valve (9) can cut out rapidly, and the pressurized air (11) in the gas holder (12) begins to expand, and water is pressed to the eminence of h from lifting pipe (10); Meanwhile, drain valve (7) is also rapid breakdown under the effect of spring (19), water, restart to flow, the water attack lift pump carries out work once more in a manner described, go round and begin again with 20 times to 90 times ceaselessly motions of per minute like this, just, constantly raise to pulsed eminence the part water of lower.

Structure characteristic of the present utility model: except with CONCENTRIC REDUCER pipe (2), three-way pipe (3), bend pipe (8), successively after the welding, in CONCENTRIC REDUCER pipe (2) portlet, three-way pipe (3) middle port, the port of bend pipe (8), welding is gone up and intake pipe (1) again, the corresponding flange (15) of drain valve gate seat of cylinder iron making (4) and gas holder (12), flange (16) and flange (14), constitute outside the pump housing of water attack lift pump, also has a drain valve gate seat (4) of cylinder iron making, particularly the lower end of portion is provided with discharge opening (18) within it, its effect is: when the water attack lift pump is worked, although the active force of the powerful water hammer that produces, can impact discharge opening (18) 20 times to 90 times with per minute equally, but these impact forces, can by be fixed on stone bolt (5) the drain valve gate seat of cylinder iron making (4) on the ground (6) pass to underground, thereby avoid or alleviate destruction discharge opening (18).

Claims

1, a kind of water attack lift pump that constitutes with pipe fitting and cast iron seat, it comprises drain valve (7), setting-out valve (9), gas holder (12), it is characterized in that CONCENTRIC REDUCER pipe (2), three-way pipe (3), bend pipe (8), successively after the welding, portlet in CONCENTRIC REDUCER pipe (2), the middle port of three-way pipe (3), the port of bend pipe (8), welding is gone up and intake pipe (1) again, the corresponding flange (15) of drain valve gate seat of cylinder iron making (4) and gas holder (12), flange (16) and flange (14), promptly constitute the pump housing of water attack lift pump, use bolt (17) to connect drain valve gate seat (4) and the gas holder of cylinder iron making (12) again, promptly constitute water attack lift pump of the present utility model.

2, structure according to claim 1 is characterized in that being provided with discharge opening (18) in the inner lower end of the drain valve gate seat of cylinder iron making (4).
