Abstract
The utility model discloses a pressure storage tank which comprises a closed water storage tank, wherein the water storage tank is connected with a water inlet pipe and a water outlet pipe; the top of the water storage tank is provided with a vacuum suppressor; the water inlet pipe is in series connection with the vacuum suppressor; a check valve is arranged between the vacuum suppressor arranged on the water inlet pipe and the water inlet end of the water storage tank; and the water outlet pipe is provided with the check valve. Compared with the prior art, the pressure storage tank disclosed by the utility model can solve the problems of fixed pressure regulation space, poor pressure and water flow regulating capacity and less adaptive purpose of the traditional non-negative pressure water storage tank.
Description
Technical field
The utility model relates to the supply equipment technical field, especially a kind of water tank that does not produce negative pressure in the pipe network that makes.
Background technology
Non-negative pressure stabilized tank is the water tank of closed, and it is a kind of source water tank that connects municipal tap water house steward and pressure pump group.The top of existing a kind of non-negative pressure stabilized tank is equipped with vacuum suppresser, and the water inlet of tank body connects tap water pipe line, and delivery port then is connected with the water inlet of water pump; The vacuum suppresser that is installed in the tank body top can discharge and extract out the gas in the tank according to the variation of liquid level in the pipe network, discharge water or water stored state to change the tank internal pressure, to change, thereby suppress the generation of negative pressure in the tank body.But after this water tank production moulding, the dischargeable capacity in the size of tank body and the tank is fixing can't to be changed, thereby the size in the pressure regulation space in the tank can not change, and causes water tank effectively to regulate the limited in one's ability of hydraulic pressure and discharge; And this water tank can only be used for as the source water tank that connects market water main and pressure pump group the buffering water pot use of the secondary pressing pump station that can't cushion more by force compensation ability as high residential building or the requirement of significantly variable working condition.
Summary of the invention
Problem to be solved in the utility model provides a kind of accumulator, existingly fixes without negative pressure water storing pressure regulation space to solve, and regulates pressure and discharge ability relatively poor, and the purposes of adaptation is problem not widely.
In order to address the above problem, the technical solution of the utility model is: this accumulator comprises the airtight water tank that is connected with water inlet pipe and outlet pipe, the top of described water tank is equipped with vacuum suppresser, be serially connected with a vacuum suppresser on the described water inlet pipe, be installed between the water inlet end of vacuum suppresser on the described water inlet pipe and described water tank a flap valve is installed; On the described outlet pipe flap valve is installed.
In the technique scheme, more specifically scheme can be: be provided with air-replacement device on the described water tank.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, is serially connected with successively low discharge vacuum suppresser and flap valve on the water inlet pipe of water tank, the water inlet pipe network that control valve is installed that can make water inlet pipe and be connected with tank body also becomes a pressure regulation space, the pressure in two pressure regulation spaces can superpose, can give at any time water tank inner supplementary pressure according to the pressure in the pipe network, and flap valve has guaranteed that the pressure in the water tank is not slackened by the pressure in the water inlet pipe, and the ability that whole accumulator is regulated pressure and current significantly strengthens; The pressure regulation space can change according to the position difference that mode and the control valve of the connection of water inlet pipe network are installed, to adapt to the operating mode of different hydraulic pressure amplitude variations;
2, this accumulator can be with the source water tank that connects running water pipe and water pump group, also can be with the buffering water pot that connects water pump group and pipe network end, all need not to install the control water valve on the water inlet pipe of water tank and the outlet pipe, the flap valve of installing on its outlet pipe can increase the pressure regulation space, and can be from water pump group or the terminal suck-back current of pipe network.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing enforcement:
Accumulator shown in Figure 1 includes airtight water tank 1, and water tank 1 top is connected with water inlet pipe 2, and water tank 1 bottom is connected with outlet pipe 8; The top of water tank 1 also is provided with vacuum suppresser 7 and pressure sensor 6; Be in series with a vacuum suppresser 3 on the water inlet pipe 2, between water inlet end vacuum suppresser 3 and water tank 1 a flap valve 4 is installed, the water side of this flap valve 4 connects the water inlet end of water tank 1, can make water inlet pipe also become a pressure regulation space (the water inlet pipe here also comprise by the end of front end the in parallel of control valve is installed or is connected in series to the water inlet pipe network of tank body water inlet), two pressure regulation spaces can pressure superposition, vacuum suppresser 3 can be given water tank 1 inner supplementary pressure at any time according to the pressure in the pipe network, and flap valve 4 has guaranteed that the pressure in the water tank 1 is not slackened by the pressure in the water inlet pipe 2.On the outlet pipe 8 of water tank 1 flap valve is installed, all need not to install the control water valve on the water inlet pipe 2 of water tank 1 and the outlet pipe 8, can increase the pressure regulation space, and can be from water pump group or the terminal suck-back water of pipe network, this accumulator can be with the source water tank that connects running water pipe and water pump group, also can be with the buffering water pot that connects water pump group and pipe network end.Be provided with air-replacement device 5 on the water tank 1, to keep the cleanliness factor of water tank 1 internal gas.
Claims (2)
1. accumulator, comprise the airtight water tank that is connected with water inlet pipe and outlet pipe, the top of described water tank is equipped with vacuum suppresser, it is characterized in that: be serially connected with a vacuum suppresser on the described water inlet pipe, be installed between the water inlet end of vacuum suppresser on the described water inlet pipe and described water tank a flap valve is installed; On the described outlet pipe flap valve is installed.
