CN2402897Y - Lock-controlled valve - Google Patents

Abstract

The utility model relates to a lock controlled valve which is integrated with the valve body and controls the fluid channel by using the lock pin and the bolt to lock the valve handle, which comprises an assembly of the valve body and the valve, a handle, a key and a lock pin assembly arranged on the valve body. A braking sleeve with tooth-like valves around is fixed on the upper part of the valve handle, and the front end of the bolt corresponding to the braking sleeve is a column milled with a stopper in the radial direction; when rotating the lock pin, the stopper of the bolt is tangentially embedded into the tooth-like valves of the braking sleeve to stop the rotation of the handle of the valve handle and lock the valve channel; otherwise, the close locking is opened so as to control the valve to start or stop. The utility model has simple structure, convenient operation, which is suitable for pipeline management.

Description

Lock controlled valve

The utility model is a kind of valve that prevents accidental or unauthorised actuation, is to belong to F16K 35/00 by International Classification of Patents.

Fluid valve in the prior art is a lot, the valve of in little tributary, often having ignored the needs cutout, only on major trunk roads, add gate valve, lead sealing loose joint valve, making like this needs cutout and should not stop to interfere with each other, unified management with a kind of state, cause the chaotic office of unnecessary waste or unreasonable stop supplies easily, bring inconvenience for management and user.

The purpose of this utility model is to overcome above-mentioned deficiency and a kind of Lock controlled valve is provided, and is that to be one with lock core dead bolt locking valve rod rotate carries out single passage cutout control position with valve body, makes the pipeline conducting with handwheel rotation valve rod poppe tvalve core when opening lock.

The purpose of this utility model is achieved in that a kind of Lock controlled valve, include the valve body valve assembly, handwheel, key and be loaded on lock core assembly parts on the valve body, it is characterized in that valve body 6 along valve rod 5 to lengthening, upper end-hole links with lid 2, bullet lock 3 is equipped with at one side lug place, upper end, spring marble is 90 ° of two off-position structures, the lock core dead bolt front end of lock 3 is the block 4 that mills one of cylindrical radial, on wear slid over cover 2 center holes and connect the valve rod 5 of handwheel 1, at position, valve pocket upper end is prism, prism can be a tri-prism, quadrangular or polygon prism, corresponding equipped binding braking sleeve 7 on it.Braking sleeve 7 underparts are along the circumferential tooth lobe that can prop up after 90 ° of block 4 rotations that is furnished with, and it can be uniform or not uniform, and its lower end surface is higher than plane on the block 4 when not working; Can be parallel or overlap by lock core dead bolt center line vertical surface and valve rod 5 center line vertical surfaces.The block that rotational lock core connects 4 of unblanking during work changes 90 ° thereupon and replaces in tooth lobe one side, and locking braking sleeve 7 stops valve rod 5 to rotate, and the shape of surface of contact is a matching surface therebetween.

The utility model advantage compared with prior art is: because lock is an one with valve body, be convenient to the single management of pipe branch, simple in structure, easy to operate, ensure heat supply, supply water safe and reliable, can not produce misoperation and close the passage that should not close, make things convenient for the user to manage voluntarily or be engaged in industry unit unified management.The valve rod braking sleeve adopts prismatic binding, and is easy for installation and do not decrease valve rod intensity.

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

Fig. 1 is a general structure schematic representation of the present utility model.

Fig. 2 is a locking structure schematic representation of the present utility model.

Fig. 3 is the non-locking plan structure schematic representation of valve rod.

Fig. 4 is that valve rod and other plant brake tooth lobe cover and connect schematic representation.

Referring to Fig. 1, a kind of Lock controlled valve, mainly by handwheel 1, lid 2, be installed on lock 3 on the valve body 6, the lock core dead bolt and have block 4, valve rod 5, braking sleeve 6 to constitute, valve body 6 along valve rod 5 to lengthening, bullet lock 3 is equipped with at its upside band lug place, upper end-hole links with lid 2, passing valve rod 5 outer ends and the handwheel 1 that cover 2 center holes connects, locking 3 positions is can be to become vertical position with the connection duct orientation outside the valve body 6 upside lugs, spring marble is 90 ° of two off-positions, and lock core dead bolt front end is the link stopper 4 that mills one of cylindrical radial; Valve rod 5 is a tri-prismoid at the valve pocket upper part, referring to Fig. 2,3, is to cooperate with corresponding braking sleeve 7 to install.Braking sleeve 7 end portions are along circumferential uniform three tooth lobes, and the lower end surface is higher than the last plane of block 4 when not working, and lock core and valve rod 5 center lines are in same vertical plane.Referring to Fig. 4 is the equipped structural type of another valve rod, braking sleeve four prisms cylinder.When work needs lock to break valve passage, rotate the handwheel throttle down, inject lock core with key and change 90 °, dead bolt block 4 changes in the tooth lobe of cutting braking sleeve 7 after 90 ° thereupon and replaces it, enforcement limits valve rod 5 rotations and opens valve again braking sleeve 7 locking, transfers to key just promptly to finish.Otherwise then open valve passage.

Claims (2)

1. Lock controlled valve comprises valve body valve assembly, handwheel, key and is loaded on lock core assembly parts on the valve body, it is characterized in that:

A. to lengthening, upper end-hole and lid (2) link valve body (6) along valve rod (5), and top one side lug is equipped with bullet lock (3), and lock core dead bolt front end is the block (4) that mills one of cylindrical radial;

B. valve rod (5) be a prism in valve pocket upper end, corresponding equipped binding braking sleeve (7), and braking sleeve (7) underpart is along the circumferential tooth lobe that can prop up after 90 ° of block (4) rotations that is furnished with, and the lower end surface is higher than plane on the block (4) when not working; Be parallel or overlap by the lock core dead bolt center line vertical surface and the vertical surface of valve rod (5) center line.

2. Lock controlled valve according to claim 1, the tooth lobe that it is characterized in that braking sleeve (7) underpart along circumferential can be uniform or not uniform.
