Abstract
The utility model relates to a two-point locking lockable valve which consists of a valve body, a valve rod and a locking cap. Wherein a locking hole which is perpendicular to the axial direction of the valve rod is opened in the locking cap and the locking hole corresponds to a stepped concave groove opened on the outer wall of the valve rod; a locking shaft is arranged along the axial direction of the locking hole, the front end of the locking shaft is matched with the stepped concave groove and the back end is contacted with one end of a inside spring; a dead hole is arranged along the centerline of the locking shaft and a steel ball is arranged in the dead hole which is opened on the tail end of the locking shaft and is perpendicular to the centerline of the locking shaft; a rotary block is sleeved in connection with the locking shaft along the outer wall of the locking shaft, the front end of the rotary block is matched with the stepped concave groove and the back end is contacted with one end of an outside spring, and the other ends of an inside and the outside springs are contacted with the inner wall of the locking cap. The utility model is characterized by simple structure, convenient production and operation, higher security and reliability and wide application range.
Description
One, affiliated technical field
The utility model relates to a kind of locking valve, especially a kind of 2 locking locking valves that are applied in the heat supplying pipeline.
Two, background technique
At present, the northern area of China heat supply in winter adopts and divides the family pay charge way, for preventing the situation of being in arrears with heating fee; Usually on each user's heating inlet pipeline locking valve is installed, this valve is some locking mechanisms, uses private key or instrument this valve can be opened and closed.So exist problems such as easily destroyed, safety reliability difference.
Three, summary of the invention
The purpose of this utility model provides sharp 2 safe and reliable locking locking valves.
For achieving the above object, 2 locking locking valves of the utility model comprise valve body, valve rod, lock nut, offer lockhole perpendicular to the valve rod axis direction in the lock nut, and the step groove of offering on lockhole and the valve rod outer wall is corresponding; Be provided with lock shaft along the lockhole axial direction, the step groove endoporus of the front end of lock shaft and valve rod is complementary, an end in contact of its rear end and inner spring; Along the coaxial spin-block that is socketed with of the outer wall of lock shaft, the outer hole of the step groove of spin-block front end and valve rod is complementary an end in contact of its rear end and outer spring; The other end of above-mentioned inside and outside spring contacts with the lock nut inwall; Be drilled with blind hole along the lock shaft center line, be positioned at the lock shaft tail end and the blind hole vertical with the lock shaft center line is provided with a steel ball.
Adopt said structure, at first lock nut is fastened on valve body, the valve rod, realize locking.Utilize special tool that lock shaft, spin-block two locks point are opened successively.Since increase by one locking structure, therefore safe and reliable.
The utility model has the advantages that simple in structure, making, easy to use, reliability, Security are higher, applied range.In use can play preventing that locking valve from being opened by accident effectively, thereby ensure the heating pipeline effectiveness of nursing management.
Four, description of drawings
Fig. 1 is the structural representation of 2 locking locking valves of the utility model.
Five, embodiment
As shown in Figure 1,2 locking locking valves of the utility model comprise cast iron valve body 1, valve rod 2, lock nut 3, be cast with lockhole 4 perpendicular to valve rod 2 axial directions in the lock nut 3, the step groove 2-1 that offers on lockhole 4 and valve rod 2 outer walls is corresponding, be coaxially installed with steel lock shaft 5 along lockhole 4 axial directions, the endoporus of the step groove of its front end and valve rod 2 is complementary, an end in contact of rear end and steel inner spring 7.Along the coaxial steel spin-block 6 that is socketed with of lock shaft 5 outer walls, the outer hole of the step groove of its front end and valve rod 2 is complementary, an end in contact of rear end and steel outer spring 8, and the other end of above-mentioned inside and outside spring contacts with the lock nut inwall.Along lock shaft 5 center line drillings blind hole 5-1 is arranged, be positioned at lock shaft 5 tail ends and the blind hole vertical with the lock shaft center line is placed with a steel ball 9.
In actual the use, owing to increased locking mechanism one in the program of unblanking, so Security, reliability all are improved.
The utlity model has simple in structurely, safe and reliable, applied range can play preventing that locking valve from being opened by accident in actual applications effectively, thereby ensures the heating pipeline effectiveness of nursing management.
The utility model structure can be attached in other various locking valve structures, can play the purpose that improves safety reliability equally.
