Abstract
The utility model is an antifreezing joint of a pressure gauge, and aims to prevent the pressure gauge from freezing in the winter and facilitate the production management in the winter. The antifreezing joint comprises a joint body; a plunger is installed in a pressure transmission channel of the joint body; and antifreeze is filled at the top of the plunger so as to prevent the pressure gauge from freezing and damaging by freezing. According to the utility model, the antifreeze is filled in the pressure transmission channel of the joint body, and the plunger is used to prevent the antifreeze from contacting the liquid in the pressure transmission channel; the pressure gauge can be effectively prevented from damaging by freezing; the accuracy of recording the winter production data is obviously improved; the damage of the pressure gauge is reduced; the production cost is reduced; and the workload of the worker is reduced.
Description
Technical field
The utility model relates to manometric link, and particularly a kind of antifreezing joint for pressure gauge, can prevent that tensimeter from freezing, and facilitates production management in winter.
Background technology
Be arranged at present ducted pressure tapping and just by meter connector Nei duct, carry out transmission of pressure, the liquid passing hole channel in pipeline enters in pressure tapping, makes the pressure in gauge hand indication pipeline.To winter due to temperature compare Di， China the north generally subzero below 10 degrees Celsius, thereby the liquid that makes to enter in pressure tapping freezes, the freezing or pressure misregister by tensimeter, give produce, particularly the oil well production in oil field bring many unfavorable.Often cause oil well pressure table phenomenon freezing or that generation tensimeter numerical value does not conform to actual numerical value to occur.Have a strong impact on workman on duty and enroll at the scene force value, bring much inconvenience to oil well production management, the freezing production cost that also increased of tensimeter, has also increased workload simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of antifreezing joint for pressure gauge, prevents that tensimeter from freezing, and facilitates production management in winter, improves the accuracy of means of production admission in winter.
The utility model is achieved in that a kind of antifreezing joint for pressure gauge comprises joint body, and joint body is provided with pressure transmission passage, in the pressure transmission passage of joint body, plunger is installed, and pours into anti freezing solution above plunger, prevents that tensimeter is frozen and freezing.
Compared with prior art, the beneficial effects of the utility model are: in the pressure transmission passage of joint body, pour into anti freezing solution and blocked with the liquid that enters pressure transmission passage and contacted by plunger, after site test, proving effect is good, can effectively prevent that tensimeter is damaged by frost, obviously improved the accuracy of means of production admission in winter, reduce manometric damage simultaneously, reduced production cost, alleviated workman's workload.The utility model is being processed relief hole with manometric junction, can, when changing tensimeter, further improve the security of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, referring to Fig. 1, a kind of antifreezing joint for pressure gauge comprises joint body 1, and joint body 1 is provided with pressure transmission passage, in the pressure transmission passage of joint body 1, plunger 2 is installed, and above plunger 2, pours into anti freezing solution.Joint body 1 top and manometric junction are provided with relief hole 4.The outer wall of plunger 2 is equipped with O-ring seal 3, prevents anti freezing solution seepage.The internal diameter of pressure transmission passage is less than the internal diameter of joint body 1 and tensimeter junction.First in production scene, need setting pressure Biao position, the joint body 1 that plunger 2 has been installed is arranged on tensimeter gate, in joint body 1, pour into after anti freezing solution, tensimeter is arranged on joint body 1, open the sluices and can use.While needing to change tensimeter, after closing presure table gate, slowly loosen tensimeter, can lay down the pressure in joint body 1 from relief hole 4, further improved the security of worker's constructing operation.
