Abstract
The utility model provides a lockable ball valve which only can be locked and unlocked by a special key and accordingly can effectively avoid theft. The lockable ball valve comprises a valve body, joints are arranged at two ends of the valve body, two ends of a ball are arranged in the valve body through sealing rings, a valve stem penetrates through a valve stem cavity on the valve body, the valve stem and the valve body form a rotating pair, the lower end of the valve stem is connected with the ball, and the upper end of the valve stem is lower than the periphery of the upper end of the valve stem cavity. The ball valve further comprises the key which can extend in the valve stem cavity to match with the upper end of the valve stem and is used for driving the valve stem to rotate.
Description
Technical field
Present technique relates to a kind of ball valve, specifically, but is a kind of can preventing by the random unlatching or the ball valve with lock of closing.
Background technique
Existing ball valve comprises valve body, and two ends of valve body has joint, and the two ends of ball are arranged in the valve body through seal ring, and the valve-rod cavity that valve rod passes on the valve body also and between the valve body forms revolute pair, and the valve rod lower end links to each other with ball; The upper end of valve rod links to each other with the handle on valve body top.Drive valve rod through handle, realize the rotation of ball, drive the open and close of valve.But this ball valve anyly can arbitrarily rotate handle per capita and comes switch valve, does not have the theft protection function.
Summary of the invention
The purpose of present technique provides a kind ofly can only use the private key open and close, but the ball valve with lock that the phenomenon that can effectively avoid theft takes place.
But this ball valve with lock comprises valve body, and two ends of valve body has joint, and the two ends of ball are arranged in the valve body through seal ring, and the valve-rod cavity that valve rod passes on the valve body also and between the valve body forms revolute pair, and the valve rod lower end links to each other with ball; The upper end of valve rod is lower than the periphery of the upper end of valve-rod cavity, and this ball valve comprises that also can be stretched into a key that is used to drive the valve rod rotation that matches with the upper end of valve rod in the valve-rod cavity.
The beneficial effect of present technique: this valve can only use key just can stretch into valve-rod cavity and match with the valve rod upper end, rotates thereby drive valve rod, realizes valve switch, and the phenomenon that can effectively avoid theft takes place.
But above-mentioned ball valve with lock, the lower end of valve rod has thrust journal, and thrust journal is positioned at the thrust step of valve-rod cavity bottom.Adopt this structure, valve rod adopts from lower to upper and installs, and effectively avoids causing valve rod upwards to be scurried out because of pipeline pressure is excessive.
But above-mentioned ball valve with lock is provided with the limiting gasket that is used for limiting the valve rod rotation angle on the top of valve-rod cavity, and valve rod rotates in this angle, can be in valve opening and close two states.The keying of valve realizes spacing through limiting gasket, changed spacingly through the lug on the valve body in the past, and it is also more attractive in appearance both to have saved copper material profile.
Description of drawings
But Fig. 1 is the ball valve with lock schematic representation.
Fig. 2 is the structural representation of valve rod.
Fig. 3 is the plan view of Fig. 2.
Fig. 4 is the schematic representation of limiting gasket.
Embodiment
But referring to ball valve with lock shown in Figure 1, comprise valve body 1, two ends of valve body has joint 2, and the two ends of ball 4 are arranged in the valve body through seal ring 3.The valve-rod cavity that valve rod 5 passes on the valve body also and between the valve body forms revolute pair, and the valve rod lower end links to each other through groove with ball.The upper end 51 of valve rod is lower than the periphery 11 of the upper end of valve-rod cavity.The lower end of key 10 can be stretched in the valve-rod cavity and match with the upper end of valve rod, is used to drive valve rod and rotates.Key extension lever 12 passes the top of key 10.
The lower end of valve rod has thrust journal 52, and thrust journal is positioned at the thrust step of valve-rod cavity bottom.
Referring to Fig. 4, be provided with the limiting gasket 7 that is used for limiting the valve rod rotation angle on the top of valve-rod cavity, valve rod rotates in this angle, can be in valve opening and close two states.Back-up ring 8 is positioned at limiting gasket 7 tops of valve-rod cavity, moves axially to prevent limiting gasket.When key 10 is taken out, fill in the valve-rod cavity upper end with Plastic cap 9 on valve-rod cavity.
Connect through groove between valve rod 5 and the ball 4, when key 10 rotation valve rods 5, drive ball 4 and rotate, thus the open and close of realization valve.Through 6 sealings of twice O type circle, seal through the F4 seal ring between ball 4 and valve body 1, the joint 2 between valve rod 5 and the valve body 1.Key 10 is enclosed within 5 last times of valve rod, and rotation valve rod open and close valve makes to rotate through limiting gasket 7 to stop, and flow is maximum when guaranteeing valve opening, and is watertight when closing.
One of characteristic of this product specification: valve rod 5 adopts from lower to upper to be installed, and effectively avoids causing valve rod to be scurried out because of pipeline pressure is excessive.
Two of the characteristic of this product specification: the keying of valve realizes spacing through limiting gasket 7, has changed in the past through lug on the valve body spacingly, and it is also more attractive in appearance both to have saved copper material profile.
Three of the characteristic of this product specification: valve can only use the private key open and close, and the phenomenon that can effectively avoid theft takes place.
Claims (3)
1. but a ball valve with lock comprises valve body, and two ends of valve body has joint, and the two ends of ball are arranged in the valve body through seal ring, and the valve-rod cavity that valve rod passes on the valve body also and between the valve body forms revolute pair, and the valve rod lower end links to each other with ball; It is characterized in that: the upper end of valve rod is lower than the periphery of the upper end of valve-rod cavity, and this ball valve comprises that also can be stretched into a key that is used to drive the valve rod rotation that matches with the upper end of valve rod in the valve-rod cavity.
2. but ball valve with lock as claimed in claim 1 is characterized in that: the lower end of valve rod has thrust journal, and thrust journal is positioned at the thrust step of valve-rod cavity bottom.
