Abstract
The utility model provides a threaded ceramic gas nipple. The threaded ceramic gas nipple comprises a ceramic gas nipple core and a base body, wherein the base body is wrapped outside the ceramic gas nipple core; threads are formed on the outer side of the base body and matched with the internal threads of the gas nipple base; a venthole is formed in the center of the ceramic gas nipple core; and one end of the ceramic gas nipple core is trumpet-shaped. The threaded ceramic gas nipple is easy to replace, simple to operate, small in size and low in cost, and has the advantages of abrasion resistance, scouring resistance, solidness, durability and long service life.
Description
Technical field
The utility model relates to a kind of oil gas field gas recovery well throttling arrangement, particularly a kind of oil gas field gas well exploitation valve of throttling arrangement.
Background technology
In recent years, the general composite ceramic valve that adopts of oil gas field gas well gas production, it is comprised of metab and composite ceramics mouth core component, and for effect has been brought into play in the oil field gas production, but it exists following shortcoming or deficiency simultaneously: 1. volume is large, cost of manufacture is high; 2. change the valve inconvenience.Because this ceramic air faucet base and mouth core are connected as a single entity, want the integral replacing valve when adjusting working system (valve of different-diameter) at every turn, the operating time is long is unfavorable for that gas well steadily produces, and has also increased cost of production and operating personnel's labour intensity simultaneously.In addition, ceramic air faucet utility model patent ZL2010 2 0172354.1.It is mainly at mouth body installed inside composite ceramics mouth core, is that acidproof, antiwear characteristics and the metal material toughness with pottery organically combines, and has anticorrosive, wear-resistant advantage.The replacing difficulty is large, shortcoming that cost of manufacture is high but in use expose.
The utility model content
The purpose of this utility model is to overcome to change the deficiency that difficulty is large, cost of manufacture is high, provides a kind of rational in infrastructure, and build is less, change small-sized screw-type ceramic air faucet easily.
The technical scheme that the utility model adopts is: the screw-type ceramic air faucet, comprise ceramic air faucet core, matrix, and the ceramic air faucet core is divided into the different two parts of diameter, and the outside of ceramic air faucet core is coated with matrix; The outer sidecar of matrix has screw thread, matches with the internal thread of valve base; Ceramic air faucet core center is provided with air vent, and an end of ceramic air faucet core is bell mouth shape.The ceramic air faucet core is as a whole.The internal diameter of air vent can differently according to the diameter of ceramic air faucet core change.
Invention difference with the prior art of the present utility model: the part in original technology has metab and check pin and pore, and metab has a kind of adhesive to join together in ceramic mouth core, and volume is larger, can't change ceramic mouth core; The art of this patent has been invented in No. 54 steel matrix of ceramic mouth core outsourcing, and at the described matrix screw thread of getting on the bus out, then with on the valve base also car go out screw thread, described ceramic mouth core is rotated in described valve base.
The utility model has following advantage compared with prior art: is easy to change, and simple to operate; Volume is little, and cost is low; Wear-resisting resistance to erosion, sturdy and durable, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 is the ceramic air faucet core, and 2 is the ceramic air faucet core, and 3 is matrix, and 4 is horn mouth.
The specific embodiment
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
The screw-type ceramic air faucet comprises ceramic air faucet core 1 and 2, matrix 3, and the ceramic air faucet core is divided into different two parts of diameter 1 and 2, and ceramic air faucet core 1 and 2 outside are coated with matrix 3; The outer sidecar of matrix 3 has screw thread, matches with the internal thread of valve base; Ceramic air faucet core 1 and 2 centers are provided with air vent, and ceramic air faucet core 1 and an end of 2 are horn mouth 4 shapes.Ceramic air faucet core 1 and 2 is as a whole.The internal diameter of air vent can differently with 2 diameter according to ceramic air faucet core 1 change.
