Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing skids, in particular to an alarm type digital display valve for a gas pressure reducing skid. Background Art

[0002] Pressure reducing skid is a kind of equipment used in natural gas pressure reducing station. Pressure reducing skid usually refers to CNG pressure reducing skid. CNG pressure reducing skid is a pressure reducing skid equipment collection that integrates many functions such as filtration, metering, odorization, pressure reducing, etc. It is generally used to receive pipeline natural gas or unload CNG transport vehicles. The pipeline of the pressure reducing skid is equipped with a digital valve. When natural gas passes through the pipeline of the pressure reducing skid, the digital valve displays the pressure of natural gas. The gas pressure sensor inside the digital valve detects the pressure of natural gas. However, the existing digital valves for pressure reducing skids still have shortcomings when used. When the pipeline pressure is too high, the digital valve displays the natural gas pressure, but the pressure cannot be shared immediately, which is not conducive to protecting the pressure reducing skid equipment. In addition, the digital valve cannot be connected to multiple pipelines at the same time, resulting in the pressure reducing skid requiring more space to install multi-channel pipelines.

[0003] After searching, the utility model patent with announcement number CN217272306U discloses an alarm type digital display valve for gas pressure reducing skid, including a valve seat, a third conduit is installed at one end of the valve seat, a fourth conduit is installed at the other end, a digital display host is installed on the top of the valve seat, a first conduit is installed on the top of the third conduit, and a second valve is installed on the first conduit, a tank body is installed on the top of the first conduit, and an exhaust assembly is installed on the tank body; the exhaust assembly includes an exhaust pipe installed on the top of the tank body and a first valve installed on the exhaust pipe. In this utility model, the failure rate of the pressure reducing skid is reduced by setting the tank body and installing the first conduit on the tank body. By installing a multi-channel pipeline connection assembly on the pipelines at both ends of the valve seat, no extra space will be occupied, and the digital display valve is easier to install on the pipeline of the pressure reducing skid.

[0004] The above-mentioned prior art still requires manually opening the control valve after hearing the buzzer when reducing the gas pressure in the conduit, which is not efficient enough. Therefore, the utility model proposes an alarm-type digital display valve for a gas pressure reducing skid. Utility Model Content

[0005] The utility model aims to provide an alarm type digital display valve for a gas pressure reducing skid, which solves the problems raised in the background technology.

[0006] The embodiment of the present application provides an alarm-type digital display valve for a gas pressure reducing skid, comprising a base, a support rod fixedly installed on the upper end of the base, a fixed plate fixedly installed on the upper end of the support rod, a valve seat fixedly installed on one side of the fixed plate, a first conduit fixedly installed on the left side of the valve seat, a second conduit fixedly installed on the other end of the first conduit, a square tube fixedly installed on the other end of the second conduit, and a third conduit fixedly installed on the other end of the square tube, a fixed rod fixedly installed on the upper end of the first conduit, a digital display host fixedly installed on the upper end of the fixed rod, a control valve fixedly installed on the conduit next to the digital display host, a gas filling pipe fixedly installed on the side wall of the control valve, a gas storage tank fixedly installed on the upper end of the control valve, a discharge pipe fixedly installed on the upper end of the gas storage tank, a gas stop valve fixedly installed on the discharge pipe, a support rod fixedly installed on the lower end of the gas storage tank, and the lower end of the support rod fixedly installed on the conduit.

A gas pressure sensor and a controller are installed inside the digital display host. The controller controls the operation of the gas pressure sensor. The gas pressure sensor is used to detect the pressure of the natural gas passing through the control valve. The air pressure in the control area of ​​the control valve can be adjusted through the gas filling pipe. When the natural gas passes through the control valve, if its pressure is too high, it will push the baffle up, and the gas will be ejected through the pressure relief port, reducing the pressure in the conduit to achieve automatic pressure reduction. The ejected gas is stored in the gas storage tank. When necessary, the air stop valve on it is opened to release the gas in the tank. When the pressure relief port is blocked or other conditions occur, causing the pressure in the air pressure area to be too high, the controller controls the alarm to sound an alarm and notify the staff to check the control valve. When disassembly is required, pull the locking rod upwards, and then pull the locking plate so that the arc on it corresponds to the locking rod, and then it can be disassembled.
