Abstract

The utility model relates to a pipe pressure controller. The utility model has a primary structure that a returning pipe is additionally arranged between a water inlet pipe and a water outlet pipe. According to the pressure which is indicated by a pressure gauge which is arranged on the water outlet pipe, the water supply quantity and the pressure can be freely regulated through the opening and the closing of a control gate valve which is installed on the returning pipe, the pressure which is required by uses can be maximally satisfied, the water consumption can be improved, and the water resource can be saved. Simultaneously, the utility model has the advantages of low cost, and convenient installation and operation.

Description

The pipeline pressure control device

The utility model relates to a kind of control pressurer system, particularly relates to a kind of pipeline pressure control device.

In the water service process in city, the hydraulic pressure of tap water usually can great changes will take place because of the urbanite water consumption situation, and under the certain situation of output, when water use peak, water pipe hydraulic pressure is corresponding less, and siphon pressure is then bigger during the water ebb; So some users that stay in high building usually do not have water because of the hydraulic pressure deficiency when water use peak; If the increase output, then the pressure of water pipe is corresponding will increase, and feed pipe is difficult to again sustain high pressure for a long time and easily breaks like this.In order to regulate the pressure of supply water of water pipe, various pressure regulation current-limiting apparatus have just been produced on the market, disclose " the pipeline pressure regulation current-limiting apparatus " that a kind of patent No. is ZL92217014.2 as Patent Office of the People's Republic of China, it is that a current limliting cover by spring-loaded is set in the feed pipe part, to play the effect of balanced part water pipe pressure of supply water, and can not carry out pressure regulation to the whole water supply pump system of water pump, can not increase the output of whole system.

The purpose of this utility model just provides a kind of pipeline pressure control device, and it can carry out pressure regulation and suitably regulate output the whole water system of water pump, keeps the normal operation of water system, makes water supply line unlikely breaking under the situation of carrying at full capacity.

The purpose of this utility model is achieved in that it is made up of water inlet pipe, water pump, outlet pipe, pressure meter etc., between the water inlet pipe of water pump and outlet pipe, set up a return duct, be provided with on the return duct according to being installed in the shown pressure adjustable size joint output of pressure meter on the outlet pipe and the control gate valve of pressure.

Below in conjunction with the drawings and specific embodiments the utility model is done further to describe in detail:

Fig. 1 is the utility model pipeline location schematic diagram.

Pipeline pressure control device as shown in the figure is made up of water inlet pipe 1, water pump 2, outlet pipe 3, pressure meter 4; Between the water inlet pipe 1 of water pump 2 and outlet pipe 3, return duct 6 is installed, control gate valve 5 is installed on return duct 6, pressure meter 4 be contained on the outlet pipe 3 and the position of return duct 6 inlet belows on.

As resident during at water use peak, the pressure value of demonstration that is installed on the pressure meter 4 on the outlet pipe 3 can be closed the control gate valve 5 on the return duct 6 when setting numerical value, and the output of whole system is increased, and the numerical value that pressure meter 4 shows promptly increases; When the water ebb, when the numerical value that pressure meter 4 shows surpasses setting pressure, can suitably open control gate valve 5, make part water flow back into the oral siphon 1 of water pump 2 through return duct 6, so just reached adjusting whole pipe pressure water-supply system ductwork pressure, and the purpose that can regulate the output of water system.

The control gate valve 5 of this pipeline pressure control device as employing pressure controller are controlled its pressure, can make the pressure of whole water system be adjusted to a steady state value automatically, realize the automation of operation control.Alleviate the labour intensity of work, and can reach best control effect.Make and original become controlled pressure for the people by pressure control people.

The utility model is installed return duct because of adopting on the water pump inlet tube and outlet tube, can regulate ductwork pressure arbitrarily by adjusting the control gate valve on the return duct, solved the shortcoming that general reducing valve only is applicable to local water system, and utilize the short path principle of return duct, can regulate the output and the required pressure of users of whole water system arbitrarily, guarantee the normal water supply operation of equipment, improved water supply volume, saved the water supply energy.The native system equipment price is cheap, and is easy to install.

Claims

A kind of pipeline pressure control device, by water inlet pipe (1), water pump (2), outlet pipe (3) be installed on pressure meter (4) on the outlet pipe (3) etc. and form, it is characterized in that between water inlet pipe (1) that connects water pump (2) and outlet pipe (3), having set up return duct (6), on return duct (6), be provided with the control gate valve (5) that the pressure adjustable size that shows according to pressure meter (4) saves output and pressure.
