Abstract
A guard against theft sampling value belongs to the value technical field, which is characterized in that the guard against theft sampling value comprises a front value body of the arc interface, a back interface, an airproof steel ball, a gliding handspike, a spring, an oil warehouse cover and a screw. The front end of the front value body sets an elastic collar fixed oil warehouse cover, and the oil warehouse cover connects the spring, with the other end of the spring connected with the directing steel ball seat. The airproof steel ball and the airproof steel ball seat compose the airproofing of the oil warehouse, with the end of the front value body sleeved with a sliding handspike, the front end sleeved with a spring, the oil output port of the front value body connecting the manometer seat, and an O-typed cushion is arranged at joint between the sliding handspike and the front and the back value body. The utility model is of a simple structure and an ideal guard against theft effect, changes the prior oil field sampling value body used commonly, reduces the flux and achieves the guard against theft requirement.
Description
The utility model belongs to valve technology field, the anti-theft sampling valve that in particular a kind of crude oil that is used to control the well head pipeline is stolen.
At present, the sample cock that the oil field is used for pipeline mostly is common gate valve or needle value, and these two kinds of valve mechanisms are unreasonable, can not prevent that crude oil is stolen.
The purpose of this utility model provide a kind of rational in infrastructure, prevent the anti-theft sampling valve that crude oil is stolen, to overcome the defective that prior art exists.
The technical solution of the utility model is achieved in that it is a front valve shell by the arc interface, sealed steel ball, pusher, spring, the bunker end cap, rear valve body and screw rod constitute, the front end of front valve shell is provided with fixedly bunker end cap of circlip, the bunker end cap connects spring, the other end of spring connects orientation steel ball cup, sealed steel ball and steel ball sealing seat constitute the sealing of bunker, the terminal socket pusher of front valve shell, the pusher front end is with spring, the oil outlet place of front valve shell connects the pressure gauge stand, pusher with before, the joint of rear valve body is provided with O type cushion rubber.
When reducing the screw rod precession and the contact wear that causes of pusher, between screw rod and pusher, cooperate to be provided with steel ball, and have spherical groove in the cooperation place respectively.
Good effect of the present utility model is:
1. because the interface of front valve shell is curved, integrally welded with the well head pipeline, prevent stolen.
2. valve body is provided with small-bore oil outlet, has dwindled oil flow.
3. socket spring on the pusher, and rear valve body has screw thread, if the screw rod that does not match with rear valve body is difficult to remove the sealing of valve body.
In sum, the utility model anti-theft effect ideal has changed sampling valve body in oil field commonly used at present fully, has reached antitheft requirement.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing is a structure sectional view of the present utility model.
With reference to accompanying drawing, the utility model is the front valve shell 11 by the arc interface, the rear valve body 6 that is threaded with front valve shell 11, sealed steel ball 12, pusher 4, spring 9, bunker end cap 1 and screw rod 7 constitute, the front end of front valve shell 11 is provided with circlip 13 and is used for fixing bunker end cap 1, bunker end cap 1 connects spring 9 and to 9 position-limiting actions of spring, the other end of spring 9 is socketed on the orientation steel ball cup 2, sealed steel ball 12 and steel ball sealing seat 3 constitute the sealing of bunkers, the terminal socket pusher 4 of front valve shell 11, pusher 4 front ends are with spring 9, the oil outlet place of front valve shell 11 connects pressure gauge stand 10, pusher 4 with before, the joint of rear valve body is provided with O type cushion rubber 5.When reducing screw rod 7 precessions and the contact wear that causes of pusher 4, between screw rod and pusher, cooperate to be provided with steel ball 8, and have spherical groove in the cooperation place respectively.
During the utility model work, the screw rod precession promotes pusher, and pusher promotes sealed steel ball, and the sealing in the releasing valve body between sealed steel ball and the steel ball sealing seat makes the crude oil in the bunker be used for sampling from micro-outflow of oil outlet; Sampling finishes, and screw rod screws out, and the valve inner member recovers complete sealing state.
