TH8312C3 - Water meter assembly - Google Patents

Abstract

DC60 (21/8/56) water meter assembly It was invented to solve the problem of large water meters. Which cannot read the water flow with a weak flow rate It is assembled in a set: a large meter has a spring-loaded check valve installed in front of it before entering the meter. To use the flaps of the check valve to control the opening-closing in case of soft water flow rate. When flowing through a large scale The gauge will not be able to read the readings, and the spring will pull the check valve flaps completely. So that the water does not flow through Will cause water loss At the same time there will be Use a three-way installation at the water inlet in front of the check valve and then connect the pipe through a small meter around to meet at the outlet. Behind the big scale So that a small scale reads the value instead And have water used all the time If the water flow rate is normal, the water pressure can be pushed through the check valve flaps to push the impeller of the large gauge, making the readings normally. The other part of the water will flow indirectly through a small meter which has a readout all the time.When the water flow through the two meters is combined, it is equal to the amount of water that is actually measured by measuring.

Claims (1)

1. Water meter assembly It consists of a spring (3) check valve installed on the water inlet side. The face of a large water meter (7) to control the opening - closing. According to the water flow rate, a three-way (2) is installed on the water inlet side, in front of the spring-type check valve (3), and then connected to the brond pipe (14), an elbow (15), a short pipe (13). ) The straight connector (17) then converges with the waterway of the small meter (18), respectively, and is installed three ways (10) on the water outlet side behind the large meter (7) and then connects to With brond pipe (22), elbow (21), short pipe (20), straight connection (19), then converge into the small meter outlet water outlet (18) respectively, and from spring type check valve (3) there is Short pipes were used to have the lengths of the standard of the Metropolitan Waterworks Authority up to the large meters (7) at the water inlet side and from the large meters (7) short pipes of the standard length of the Metropolitan Waterworks Authority. Continue until three (10) way out of the river. With special characteristics At the water inlet in front of the large gauge (7), a spring-loaded check valve (3) was installed, with the original spring (24) replaced and a new, stronger one (25) replaced to provide value. K of the spring is higher In order to maintain the force of the check valve, it is completely closed during the weak water flow. To control the flow of water Through a large scale (7) while no reading The water inlet area in front of the spring-type check valve (3) is installed three-way (2) and is connected to the brond pipe (14), the elbow (15), short pipe (16), straight connector (17). With the small meter water channel (18) and the small meter outlet area (18) connect to the straight connector (19), short pipe (20), elbow (21) brond pipe, 22) and It converges to a three-way (10) located behind the large gauge outlet water outlet (7) to provide soft water flow. It flows indirectly through the small scale (18), which has a less tolerance than the large scale (7) to give the reading instead.
