Today, I will introduce a national invention authorized patent-a pressure-resistant pressure transmitter. The patent was applied for by Shaoxing Keqiao Drainage Co., Ltd., and the authorization was announced on January 18, 2017.

Content description

The utility model relates to a pressure-resistant pressure transmitter.

Background of the invention

The pressure transmitter is used to test the water pressure in the water pipe; the pressure transmitters currently on the market are not well sealed, and water leakage often occurs; at the same time, the pressure on the pressure transmitter is relatively small. If the water pressure in the tube is too high, the core body will be pushed toward the tube body.

Summary of the invention

The purpose of the utility model is to provide a pressure-resistant pressure transmitter, which has a simple structure, is convenient to manufacture, has high sealing performance, and can withstand greater water pressure.

Principle and design of pressure-resistant pressure transmitter

In order to achieve the above purpose, the technical solution of the present utility model is: a pressure-resistant pressure transmitter, including a valve sleeve, one end of the valve sleeve is installed with an outlet pipe, and the other end of the valve sleeve is installed with a circuit board installation Tube, the circuit board mounting tube is mounted with a circuit board at one end of the valve sleeve, a core is installed in the circuit board mounting tube, and the core and the circuit board are connected by a line; the core and the circuit board mounting tube A rubber ring is installed in between, and a blocking rod is installed between the core body and the valve sleeve.

A bolt is installed on the outlet pipe, and the bolt and the outlet pipe are integrally manufactured. The blocking rod, the valve sleeve and the core body form a right triangle. A sealing ring is installed on the circuit board mounting tube. The valve sleeve is provided with an outlet groove at one end of the outlet pipe.

A pressure-resistant pressure transmitter of the present invention includes a valve sleeve 1, an outlet pipe 2 is installed at one end of the valve sleeve 1, and a circuit board installation pipe 3 is installed at the other end of the valve sleeve 1. A circuit board 4 is mounted on one end of the valve sleeve 1 of the board mounting tube 3, a core 5 is mounted in the circuit board mounting tube 3, and the core 5 and the circuit board 4 are connected by a circuit; the core 5 is connected to the circuit A rubber ring 6 is installed between the plate mounting tube 3, which can play a sealing role and increase the friction between the two, thereby increasing the pressure that the core body can withstand. The core body 5 and the valve sleeve 1 A blocking rod 9 is installed in between, which greatly increases the pressure that the core body can withstand. A bolt 7 is installed on the outlet pipe 2, and the bolt 7 is manufactured integrally with the outlet pipe 2. The blocking rod 9, the valve sleeve 1 and the core body 5 form a right-angled triangle. The triangle principle has good stability and can increase the pressure that can be withstood. A sealing ring 8 is installed on the circuit board mounting tube 3, which plays a role of sealing. The valve sleeve 1 is provided with an outlet groove 10 at one end of the outlet pipe 2 to facilitate line installation; because the lines are covered with rubber sheaths, it is troublesome to bend too much, and the existence of the outlet groove 10 is lower. The degree of bending required for the sheath and its internal wiring.

The beneficial effects of the utility model are: the utility model has a simple structure, is convenient to manufacture, has high sealing performance, and can withstand greater water pressure.
