Description

Theft-proof sluice valve

The utility model belongs to the gate valve that a kind of pipeline is dredged gate-valve device, the especially safe antitheft of closing.

At present, the used gate valve of mediation pipeline in industries such as oil field, chemical industry, what adopt is wheeled or the rod-type spanner, because spanner, valve gap all expose, just can open easily with hand or general tool,, expect to lose to the source that makes country for the thief provides convenience, by it is that every year is not known will lose how many oil, brought massive losses to country in the oil field.

The purpose of this utility model provides a kind of theft-proof gate valve, and its safety not only easy to use is spill and leakage not, and main be to have anti-theft feature.

The purpose of this utility model is realized by following technological scheme: valve body is a Three way type, be divided into upper valve body, left valve barrel oil inlet pipe and right valve barrel oil outlet tube, being stepped shaft in the upper valve body is threaded with its parts and connects, the left side of at first packing into has the circular base gland of two seals circle, put into circular antitheft gland with scyewed joint again, be connected to a postive stop baffle that is screwed in advance under the antitheft gland, the screw rod of the square spiral shell head of a flanged dish is equipped with in valve body central authorities, seal with the U RunddichtringO between screw rod upper end and the base pressure lid, seal ring is equipped with the conical flashboard of scyewed joint in the screw rod lower end on the left of the flashboard.

The purpose of this utility model can also further be realized by following technical measures: the upper valve body top antitheft valve gap of scyewed joint, the upper valve body top left has the moving draw-in groove of lock, its the right has open keyhole, be equipped with in the antitheft valve gap three square and have a pin bearing shell of circular hole, bearing pin is contained in the left side to be sold in the bearing shell hole, is with spring on the bearing pin, on the bearing pin pin is arranged before the spring, have four locating slots on the pin bearing shell of a left side, the spring on the bearing pin is put and sell position between the bearing shell in a left side.

The utility model compared with prior art has tangible advantage and good effect, and its this gate valve uses in pipeline, have light, safe and reliable, advantage such as spill and leakage not, and main purpose has possessed antitheft function.

Below in conjunction with accompanying drawing and preferred embodiment specific structural features and effect according to the theft-proof gate valve that the utility model proposes, describe in detail as after.

Fig. 1 is the utility model gate valve main body sectional view.

Fig. 2 is the utility model gate valve valve gap sectional view.

In the drawings, 1. valve body, 2. screw, 3. antitheft gland, 4. antitheft valve gap, 5. screw rod, 6. pin, 7. spring, 8. bearing pin, 9. the pin bearing shell, 10. open keyhole, 11. seal rings, 12. flashboards, 13. seal rings, 14.U RunddichtringO, 15. base pressures lid, 16. positive stop blocks, 17. oil inlet pipes, 18. oil outlet tubes, 19. locks move draw-in groove, 20. locating slots.

See also shown in the accompanying drawing, valve body 1 is made up of upper valve body, left valve barrel oil inlet pipe 17 and right valve barrel oil outlet tube 18.Be stepped shaft in the upper valve body, each ladder all car has screw thread, two road seal rings 13 are equipped with in the cylindrical bottom of base pressure lid 15, the road earlier covers base pressure 15 scyewed joint packs in the upper valve body, postive stop baffle 16 usefulness screws 2 are fixed on the antitheft gland 3, again with scyewed joint in upper valve body, the screw rod 5 of the square spiral shell head of flanged dish is equipped with in valve body 1 central authorities, flange plate contacts with postive stop baffle 16 and plays the role of positioning, screw rod 5 lower ends and conical flashboard 12 scyewed joint, rotary screw 5 opens flashboard 12, and the oil-feed mouth of pipe is opened, the seal ring 11 that seals is equipped with in the flashboard left side, between base pressure lid 15 and the screw rod 5 U RunddichtringO 14 is housed.

A left side, upper valve body upper end has the moving draw-in groove 19 of lock, the right has an open keyhole 10, valve body 1 upper end and antitheft valve gap 4 scyewed joint, three pin bearing shells 9 that have circular hole are housed in the valve gap 4, bearing pin 8 is placed on to be sold in bearing shell 9 holes in the left side, pocketed springs 7 on the bearing pin 8, and the pin 6 of retaining spring 7 is arranged on the bearing pin 8, have four locating slots 20 on the pin bearing shell 9 of a left side.

Its working principle of this gate valve is, at first is inserted in the bearing pin head with private key, and rotary pin shaft withdraws from the moving draw-in groove of lock, backs out antitheft valve gap, with the special tool rotary screw flashboard is opened again, passes in and out oil pipe and promptly connects.
