Abstract
The utility model relates to a star-shaped three-way stop valve which is used for the process flow of the oil gas gathering and transport of the oil-gas field. The utility model can directly connect with a pressure gauge, and can also sample the oil gas. The utility model is composed of a valve body, a valve cover, a valve rod, a valve clack, a sampling mouth, etc. The utility model is used in the process flow of the oil gas gathering and transport. One three-way stop valve can replace two straight-through stop valves. One three way, one pressure meter joint and one sampling mouth are saved in installing.
Description
The utility model relates to the internal thread straight-through stop valve that connects pressure gauge and oil gas sampling usefulness in a kind of oil gas field oil-gas gathering and transferring technology flow process.
The internal thread straight-through stop valve is a large amount of a kind of stop valves that adopt in the oil gas field oil-gas gathering and transferring technology flow process, is mainly used in to connect pressure gauge and oil gas sampling.Usually connect two stop valves of pressure gauge and oil gas sampling, be connected with pipeline or equipment by the threeway of " ┫ " shape, the left end of general " ┫ " shape threeway is connected with pipeline or equipment, and the upper end is hinged with manometric stop valve; The stop valve of lower end tipping oil gas sampling.The shortcoming of prior art is to connect pressure gauge will adorn two stop valves with sampling, and when pressure gauge was connected with stop valve, a GAUGE CONNECTOR also will be adorned in the centre.A sampling pipe nipple also will be adorned in the stop valve lower end of sampling.A kind ofly can directly adorn pressure gauge, the three-way cut-off valve that can take a sample is not reported so far again.
The purpose of this utility model is in order to overcome the shortcoming of prior art, and a kind of pressure gauge of can directly adorning of design can carry out the oil gas sampling again, and dual-use material is simple in structure, is convenient to connect, switch is light and handy, sealing is reliable, inexpensive three-way cut-off valve.
The utility model is achieved in that
The utility model is on the basis of former inside screw stop valve, changes original straight-through stop valve into three-way cut-off valve.The utility model is chewed son 7, sampling flap 9, main valve clack 10, valve rod 11, valve body 12, valve gap 15, sealing plug 19, handle 20, plain washer 21, nut 22 by nut 2, handle 3, " O " shape seal ring 4,16,18, seal washer 5,14,17, gland 6, sampling and is formed, its feature is as follows: valve body 12 bottoms are equipped with to take a sample and are chewed son 7, the gland 6 that " O " shape seal ring 4 is housed with inside is fixed on the valve body, seals with seal washer 5 between gland 6 and the valve body 12; Handle 3 is contained in sampling and chews 7 bottoms, and is fixing with nut 2; Valve rod 11 is contained in the right-side cavity of valve body 12, and main valve clack 10 usefulness interference fit are fixed on the left end of valve rod 11, is fixed in the valve pocket with the valve gap 15 that " O " shape seal ring 16 is housed; " O " shape seal ring 18 is housed in the sealing plug 19, with 17 sealings of valve gap 15 usefulness seal washers, and with being threaded; The right-hand member of valve rod 11 is equipped with handle 20, plain washer 21, and is fixing with nut 22.
The utility model and original technology are relatively, owing to change straight-through stop valve into the Three way type stop valve, both can adorn pressure gauge, can carry out the oil gas sampling again, so have dual-use material, simple in structure, can save a threeway during installation, a pressure gauge is chewed son, son is chewed in a sampling, switch easy to connect is light and handy, saves material, low cost and other advantages.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
In the utility model, valve body 12 suitable for reading being provided with and the corresponding M20 of pressure gauge * 1.5 internal threads, end opening is provided with taking a sample and chews son 7 internal threads that are connected, left side mouth is provided with G1/2 " and screw thread, right mouth is the valve pocket that is connected with valve rod 11, valve gap 15, sealing plug 19; Sampling is chewed 7 and is provided with "T"-shaped duct 1, is connected with sampling flap 9 usefulness interference fit, and lower thread section both sides cut some and become the plane, so that device handle 3.
Operating method of the present utility model is: handle 20 dextrorotation can make main valve clack 10 close, and left-handedly then can open.When main valve clack 10 is opened, the indicated pressure on the observable pressure gauge dial.Handle 3 dextrorotation can make sampling flap 9 close, and left-handedly then can open.Oil gas sampling operation method is: when main valve clack 10 is in opening state, open sampling flap 9, can take a sample.
Operating method of the present utility model is: handle 20 dextrorotation can make main valve flap 10 close, and left-handedly then can open.When main valve flap 10 is opened, the indicated pressure on the observable pressure gauge dial.Handle 3 dextrorotation can make sampling flap 9 close, and left-handedly then can open.Oil gas sampling operation method is: when main valve flap 10 is in opening state, open sampling flap 9, then oil gas can flow out from "T"-shaped duct 1, carries out the oil gas sampling.
Available as required stainless steel of the utility model valve body 12 or carbon steel manufacturing, sampling flap 9 and main valve flap 10 can be made with stainless steel; Son 7 is chewed in sampling and valve rod 11 can be with stainless steel or carbon steel manufacturing, and when making with carbon steel, preservative treatment need be done in the surface." O " shape seal ring 4,16,18 can be made also available teflon manufacturing with the oil resistant temperature resistant rubber.Seal washer 5,14,17 can be with teflon or red copper manufacturing.Available as required stainless steel of other parts or carbon steel manufacturing.
The utility model can replace two internal thread straight-through stop valves; Can save a threeway during installation, son is chewed in a GAUGE CONNECTOR and a sampling.
