Description
Technical Field
The utility model relates to an injection pump technical field specifically is a through type injection pump.
Background
The balance of a district heat supply network is always a technical problem to be solved urgently in the heat supply industry, and the adjustment work is very difficult due to the existence of hydraulic coupling. The jet pump has the function of water mixing, so that the flow of a pipe network can be reduced (on the premise of ensuring the sufficient flow of a heating system in a building), and the resistance of the heat supply network in a heating station and a district can be reduced. The jet pump is a fluid-dynamic pump. The fluid power pump has no mechanical transmission and mechanical working components, and uses the energy of another working fluid as a power source to convey low-energy liquid, so that the fluid power pump has good safety when being used for pumping inflammable and explosive materials. The jet pump is the equipment that liquid in the utilized high-speed efflux through the nozzle to take out the container in order to obtain, also known as the jet pump, current jet pump, most adopt integrated into one piece structure, each part all can not be dismantled, when equipment damages after long-time the use, the staff can only dismantle whole equipment and carry out the operation of changing, greatly increased maintains the cost of changing to equipment, most jet pump fluid passage has certain angle and is not straight type simultaneously, can't guarantee the pressure and the velocity of flow that supply water sprays, thereby can't guarantee to sneak into the volume of return water through fluid pressure absorption, can lead to the return water to sneak into not enough effect that influences the heating, simultaneously supply water and return water natural mixing velocity are slower, can influence the heat supply effect of partial resident family.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a through type jet pump to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the straight-through type injection pump comprises a three-way pipe, wherein flanges are fixedly sleeved on the outer walls of three end parts of the three-way pipe, one side of the inner wall of the three-way pipe is connected with a sleeve through threads, one side, close to the center of the three-way pipe, of the inner wall of the sleeve is connected with a nozzle through threads, an injection pipe is inserted into one side, far away from the sleeve, of the inner part of the three-way pipe, a sealing gasket is tightly sleeved in the middle of the outer wall of the injection pipe and is tightly attached to the three-way pipe and the flanges respectively, and a static mixer is connected to one side, close to.
Compared with the prior art, the beneficial effects of the utility model are that: this through type jet pump, can dismantle the part through each, can be when equipment damages after long-time the use, make things convenient for the light convenient operation of dismantling the part that damages of staff and carrying out the change, the operation that the staff dismantled whole equipment and change has also been saved simultaneously, greatly reduced maintains the cost of changing to equipment, the cooperation through sleeve pipe and injection pipe simultaneously, can guarantee the pressure and the velocity of flow that supply water sprays through type water supply injection passage, the volume of sneaking into the return water through fluid pressure absorption has been guaranteed, avoid the return water sneaking into not enough influence the effect of heating, can make the quick even mixture of water supply and return water through static mixer, guarantee the effect of heat supply.
