Abstract
The utility model discloses an anti-theft gate valve which comprises a gate system, an internal lock system and an external lock system from the bottom to the top successively. The external lock system comprises a cover fixed at the top end of the internal lock system, a rod I matched with the movable cover is welded on the outside of the internal lock system, and a hole matched with a padlock is formed in the rod I. According to the anti-theft gate valve, the structure is novel, and double locks are arranged, so that effects on theft prevention, guaranteeing of completeness of devices such as oil extraction well mouths and durability can be truly provided, the oil stealing probability and the accident occurrence rate can be reduced, social security administration is facilitated, the economic benefit is improved, and low-consumption and efficient purposes are achieved.
Description
Technical field
The utility model relates to a kind of theft-proof gate valve.
Background technique
The gate valve control point of a large amount of well mouth of oil well in field, oil field, the oil outlet of oil storage tank and petroleum pipeline, because long-time (especially night) unmanned is often opened the valve stolen, and national wealth is suffered a loss, and pollute the environment, have in addition serious accident such as initiation fire.The theft-proof gate valve that adopts has following several at present:
The one, pin with the handle of chain and lock handle gate valve, but the lawless person still can sawed-off chain or breaks open a lock, as usual stolen.
The 2nd, adopt cipher lock, but password is difficult to remember, and just is difficult to control in case spread.In addition, if the lawless person smashes combination disk from the outside, allow operator oneself also not open, lose and the control of gate valve caused waste or have an accident.
The 3rd, with protective housing production wellhead or gate valve cover are got up, but make troubles for maintaining and the operation of oil well and gate valve.Want to overhaul well head or open and close that gate valve must be employed crane or electrogas welding is hung away guard shield or sever, the cost height, in case and well head or oil-gas pipeline just be difficult in time handle when going wrong, have accident potential.
The 4th, the employing common lock adds special spanner or uses special spanner to open and close gate valve separately, but the guard shield that at first will be complementary at body processing welding one cover of gate valve.Common lock is easy to destroyed or breaks, and special spanner generally adopts off-gauge three parts, five sides and abnormally-structured etc., and is easy to be copied, so anti-theft effect is undesirable, and cost is also high.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of theft-proof gate valve being provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of theft-proof gate valve, comprise lock system, internal lock system and external lock system from top to bottom successively, described external lock system comprises the movable cover body that is arranged at internal lock system top, the body of rod I that the outside weldings of described internal lock system cooperates with movable cover body, and body of rod I is provided with the hole that cooperates with padlock.
Described lock system comprises gate valve body and the valve gap that is mated, be provided with valve seat, flashboard and valve rod in the described gate valve body from top to bottom successively, the lower end of described valve rod is connected with flashboard, and the upper end cooperates with transmission shaft, and the upper end of described transmission shaft cooperates with the internal lock system.
Described valve gap is enclosed within on the valve rod, is provided with O-ring seals between described valve gap and the valve rod.
Described internal lock system comprises lock housing and is positioned at its inner core, and described core adopts 4 cover pellets shot from a slingshot, whenever is with the pellet shot from a slingshot of varying length more than 3, and the diameter of pellet shot from a slingshot is 6～8mm.
The top of described core is provided with dust cover.
Described movable cover body comprises the standing part that is connected with the outside weldings of internal lock system, and the body of rod II that flexibly connects with standing part, and body of rod II is provided with the hole that cooperates with body of rod I.
Working principle of the present utility model:
The utility model adopts the two-bolt lock of external lock system and the collocation of internal lock system; the external lock system is common padlock; after opening the external lock system; also have the internal lock system further to protect; the core of internal lock system has adopted 4 cover pellets shot from a slingshot; key is not easy to copy, and can be under adverse weather condition normal closing gate valve and can not damaging.
The beneficial effects of the utility model are, the utility model novel structure, two-bolt lock is set, can really play antitheft and assurance production wellhead etc. installed effect intact, durable, simultaneously can reduce the probability of stolen and the incidence rate of accident, be conducive to social security management, increase economic efficiency, reach low consumption, purpose efficiently.
