Problems solved by technology
The original cork is often used to take pressure or raise, and the two cannot be taken into account
For example: the automatic alcohol injection tank needs to be filled through the cork, then the pressure cannot be taken
The conventional cock has a complex structure, frequent failures, difficult maintenance, difficult operation, and prone to corrosion
Common faults include the pressure taking and relief valve not being able to be screwed, the hand wheel is easily damaged, air leakage, and cannot be repaired, etc., which seriously affect the construction work

The invention provides a multifunctional cock which comprises a cock body, a pressure-tapping valve and a pressure relief valve. A pressure-tapping installing port connected with an external pipeline is arranged at the bottom of the cock body, and a pressure tapping and guiding channel communicated with the pressure-tapping installing port is arranged in the cock body, the pressure-tapping valve and the pressure relief valve are correspondingly installed on the left side and the right side of the cock body, an installing port of the pressure-tapping valve is communicated with the pressure tapping and guiding channel through a pressure-tapping valve connecting channel, and an installing port of the pressure relief valve is communicated with the pressure-tapping valve connecting channel through a pressure guiding channel. The upper portion of the cock body is provided with a double-face slope top structure, a pressure-tapping port is formed in each side slope top, two pressure-tapping ports are mutually communicated through an internal channel and are communicated with the pressure guiding channel through pressure-tapping channels. The multifunctional cock is further connected with a pressure guiding channel pressure relief port. The cock has the advantages of being convenient to produce, simple in structure, simple and convenient to maintain, convenient to install, flexible to operate, good in sealing performance, anticorrosion, not prone to damage, capable of saving space and the like.
Description
technical field [0001] The invention belongs to the technical field of petroleum industry, and in particular relates to a multifunctional cock. Background technique [0002] In the gas production process, the wellhead is equipped with cocks for pressure and injection, but in actual production, when adding new operations, it is necessary to add injection ports or pressure ports, and there is no safety required for production. space. The original corker is often used to take pressure or raise, and the two cannot be taken into account. For example: the automatic alcohol injection tank needs to be filled through the cork, and then the pressure cannot be taken. The conventional cock has a complex structure, frequent failures, difficult maintenance, difficult operation, and prone to corrosion. Common faults include the pressure taking and relief valve not being able to be screwed, the hand wheel is fragile, air leakage, and cannot be repaired, etc., which seriously affect the c...
