Description

The lock-pressing type valve

The utility model relates to a kind of by pushing the valve that locks, and is to belong to F16K 35,/02 35/00 by International Classification of Patents.

In the prior art, using leading gate valve or adding lead sealing makes fluid line keep particular state, yet to supplying water, warming up, after particularly adopting central heating, when needing locking affluent-dividing pipeline valve, often still close major trunk roads, relate to the user that should not close, the alternate source valve is arbitrarily opened by the people on the road limit, makes it to be not easy to management, causes unnecessary loss.

The purpose of this utility model provides a kind of lock-pressing type valve, is arranged on each lateral valve of user, can add easyly by lock on every valve, implements the keying of lateral.

The purpose of this utility model is achieved in that a kind of lock-pressing type valve, is by the valve body valve assembly, and key lock body lock core assembly parts constitutes, and is the transposition switch with bullet lock, and valve constitutes closedown of pipeline or conducting by spool valve rod and seal combination annex.It is characterized in that having seam to the valve body 11 of lengthening, can load and unload by lock at valve rod 12 upper top being provided with, should include envelope dirt by lock and block up 1, loam cake 2 at stop portion along valve rod 12, skirt cover 3, lock body 4, lock core 5, spring 6, supporting ring 7, dead bolt 8, bottom 9, Returnning spring 10.Envelope dirt stifled 1 is housed on loam cake 2 center lockholes; Suit supporting ring 7 outside lock body 4 bottoms, skirt cover 3 was housed outside week, its lower end surface is symmetrical in two grooves that have the band restraining groove on 180 ° of directions of center line, slip dead bolt 8 is housed in the groove, limiting stopper is arranged at its top, the rear end boss, the bottom is seated on the bottom 9 that is connected with lock body 4, for dead bolt 4 telescopic slide flexible, can on the slip surface of bottom 9, install and be the roller guide face, dead bolt 8 rearward ends are equipped with the Returnning spring 10 that an end places lock body 4 tangential holes, spring 6 between skirt cover 3 interior edge faces and supporting ring 7 upper-end surfaces, 7 shoulders of supporting ring are compressed reliably be contained in the valve body stop portion, the lower end heads on the dead bolt 8: lock core 5 lower ends are the flat shifting block that mills oblate post both sides, assign into two dead bolt 8 rear portions protruding between.When using key rotation lock core 5, make shifting block oppress dead bolt 8 to overcome to contract behind spring 10 elastic force lock state that withdraws from seam on the valve body, on lift out by lock, dead bolt 8 stretches out under spring 10 effects and resets, limiting stopper cooperates with restraining groove on the lock body 4 lower end grooves above it, makes overhang in the sliding stroke scope.Open (or closing) valve port pipeline with the preparation spanner, take off spanner and put, push dead bolt to be contracted stretch and cooperate with supporting ring 7 shoulders and be locked in the valve body stop portion by lock.Lock core 5 lower ends can be made into the gear shifting block, and both sides cooperate start with the side single-side rack of two dead bolts, 8 rear ends, implement the valve body seam is locked.

The utility model advantage compared with prior art is: the lockhole collar extension is provided with envelope dirt and blocks up 1, prevents that the dirt muddy water from entering lockhole, influences key unlocking; Could open and close valve port after only unblanking to take off, prevent that thus the inoperative personnel from disorderly operating, can be arranged on every valve of pipeline, make things convenient for the local locks with respect of lateral, simple in structure, easy to operate, reliable operation is convenient to management, unnecessary corresponding valve rod (spool) need have specific locked position, is applicable to all types of valves.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 be this reality novel by the lock construction schematic representation.

Fig. 2 is a dead bolt parts dependency structure plan view.

Fig. 3 is the utility model overall structure schematic representation.

Referring to Fig. 3, a kind of lock-pressing type valve is to be made of valve body valve assembly, key lock body lock core assembly parts, uses the spring marble lock to be on ﹠ off switch.Valve body 11 to lengthening, and has made last seam along valve rod, supports being installed on it by lock of valve rod upper top down.Shown in Fig. 1,2, be lock body lock core assembly parts by lock, include: envelope dirt blocks up 1, loam cake 2, skirt cover 3, lock body 4, lock core 5, spring 6, supporting ring 7, dead bolt 8, bottom 9, Returnning spring 10.Envelope dirt stifled 1 is installed on lockhole top, loam cake 2 center, prevent that the muddy water dirt is in lockhole, loam cake links skirt cover 32 times, in lock body 4 is housed, lock core 5, lock body 4 outer bottom suits supporting ring 7,180 ° of lower end surface symmetrical center line that itself and bottom 10 links are to the groove that is milled with the band restraining groove, slide in the groove and adorning dead bolt 8, dead bolt 8 tops have limiting stopper to cooperate with restraining groove, on have the tail end of boss that one end is housed to be contained in Returnning spring 10 in the lock body 4 tangential holes, lock core 5 lower ends are the flat shifting blocks of cylinder two side millings, insert between two dead bolts, 8 boss, rotational lock core 5 shifting blocks pull back dead bolt 8 compression reseting springs 10, discharge the locking to seam on the valve body.Between the spring 6 of last top skirt cover 3, the lower end is pressed against 7 shoulder positions of supporting ring on the seam, and supporting ring 7 lower ends are spacing by the bottom 9 that links lock body 4 lower ends, and its gap is pressed against on the dead bolt 8.In order to reduce dead bolt 8 force of sliding frictions, can will process the supporting rolling groove on its corresponding bottom 9 slip surfaces, put behind the needle roller still like middle shape, be arranged into roller guide.After removing 8 pairs of valve body seams lockings of dead bolt, can will take off by lock, open (or closing) valve, open (or by) valve port pipe passage, will place on the seam by lock, push just Locked valve again.
