Abstract
The utility model discloses a shock absorption type pressure gauge connector. The shock absorption type pressure gauge connector comprises a connector and a core. The connector comprises a connecting end and an operational end, wherein the connecting end and the operational end are fixedly connected together coaxially, the bottom of the connecting end is opened and concaved inwards to form a barrel-like structure, the outer wall of the connecting end is provided with threads, and the inner wall of the connecting end is provided with threads at the position of the opening. The core is formed by fixedly connecting two sections of cylinders, wherein the diameter of the core upper cylinder is smaller than the diameter of the core lower cylinder, the bottom of the core lower cylinder is provided with a lower diversion trench, the top of the core upper cylinder is provided with an upper diversion trench, the core lower cylinder is provided with threads which are matched with the threads at the position of the opening in the inner wall of the connecting end, the sidewall of the core upper cylinder is provided with a helical groove, and the bottom of the core lower cylinder is provided with a liquid inlet hole. Due to the buffer effect of the helical channel and the through hole, the liquid flow direction is changed for many times, so the purpose of shock absorption can be realized, the buffer effect can be used to ensure the bourdon tube of the pressure gauge will not be expanded or contracted sharply, so that the accurate and reliable pressure readings can be obtained, and the prolonged service life of the pressure gauge can be ensured at the same time.
Description
Technical field
The utility model relates to a kind of manometric erection joint, relates to specifically a kind of pressure tapping of energy damping, buffering.
Background technology
pressure tapping has protection tensimeter copper screw thread and realizes the metric and English screw thread and a kind of pipe fitting of existing as a kind of, be widely used in oil, chemical industry, the fields such as machinery, in process of production, gas in the road pipeline or hydraulic pressure working pressure table show, tensimeter is connected connecting portion and is generally used joint to connect with production line, existing joint is screwed connection, after making joint sealing, uses the rotation screw thread, pressure in pipeline is the interval that is in a fluctuation, especially in the situation that pressure jump, the impact of pressure butt junction is just very large, cause reading error larger, especially even more serious in this type of phenomenon of the equipment exit of pump class, if the pressure of equipment changes when being in all the time the situation of sudden change, can seriously reduce the serviceable life of pressure tapping, even reduce manometric serviceable life, causing simultaneously installation or replacing tensimeter or pressure tapping is a kind of maintenance job comparatively frequently.
The utility model content
The purpose of this utility model will be eliminated above-mentioned the deficiencies in the prior art and shortcoming exactly, provides a kind of simple in structure, the pressure tapping with damping, buffering effect.
For reaching above-mentioned technique effect, the utility model adopts following technical scheme: a kind of damping, buffering pressure tapping comprises: joint and fuse, joint comprises link and operating side, link is fixedly connected with the operating side is coaxial, described link bottom opening, and inwardly be recessed into barrel-like structure, the outer wall of link arranges screw thread, and inwall arranges screw thread at opening part; Fuse is fixedly connected with by the two-section right cylinder, on fuse, cylinder diameter is less than right cylinder under fuse, under fuse, right cylinder arranges screw thread and link inwall opening part screw thread is complementary, and on fuse, cylindrical sidewall arranges spiral groove, and under fuse, cylindrical base is provided with inlet opening.
Preferably, under described fuse, cylindrical base is provided with lower diversion trench.
Preferably, on described fuse, the right cylinder top is provided with diversion trench.
Preferably, on described fuse, cylinder contacts setting with the link inwall.
Preferably, the operating side of described joint is positive hexahedron structure.
The beneficial effects of the utility model:
the utility model mainly is comprised of joint and fuse two parts, joint one end and tensimeter screwed connection, the other end is equipped with fuse, fuse has diversion trench and spiral groove, coordinate with inner nosepiece wall after spiral groove is connected with the joint spiral at fuse and form helical duct, guarantee not sharply expansion or contraction of pressure gage spring tube by this passage buffer action, thereby obtain pressure value of reading accurately and reliably, guarantee that simultaneously tensimeter extends serviceable life, fuse has through hole and diversion trench, liquid stream is entered in tensimeter along helical duct smoothly, due to the buffer action of helical duct and through hole flow direction change repeatedly, thereby reach the damping, buffering purpose.
