Problems solved by technology
Because the valve core is spherical, the larger the caliber, the greater the ratio of the valve core material to the valve body material, and the higher the manufacturing cost, which is not conducive to production and sales. Sand particles and some foreign matter in the domestic sewage will stay in the valve body, causing it to fail to open and close normally
If the valve is placed outdoors without a lock or anti-theft device, there will be some safety hazards, so the current valves do not meet the requirements of cheap manufacturing, anti-sand, anti-theft and can be used for domestic sewage

Embodiment Construction
[0013] As shown in Figure 4, first place the valve core (3) in the valve body B (10), fill the waterproof material (6) in the circular groove of the valve body B (10), and then insert the valve stem (2) from the The circular groove on the valve body B (10) passes through and is placed in the square groove on the spool (3). Pass the waterproof gasket (9) and the upper bonnet (7) through the valve stem (2), and then fasten the valve body B (10) with bolts, and then connect the valve body A (5) to the valve body B (10) Tighten with bolts, seal with a waterproof gasket (4) in the middle, then fill the filler into the groove of the upper valve cover (7), and finally put the handwheel (1) on the valve stem (2) and use the screw Fasten.
[0014] exist figure 2 , Figure 4 with Image 6 Among them, there are two or more lock grooves in the valve stem (2). When locking is required, the valve is kept fully open, closed or in other required states, and then the key (8) is placed in ...

The invention relates to an anti-theft half ball valve which comprises a hand wheel (1), a valve rod (2), a valve element (3), a valve body A (5), a valve body B (6), an upper valve cover (7) and a key (8). The anti-theft half ball valve is characterized in that the valve element (3) is formed by cutting a ball into a C shape; and the key (8) is arranged between the valve rod (2) and the upper valve cover (7). The anti-theft half ball valve has light weight, low manufacture cost, good tightness and the functions of anti-theft and sand proofing and can be used for the on-off of domestic sewage, and moreover, the anti-theft half ball valve has strong practicability and universality so as to have good market and prospect.
Description
Technical field [0001] This invention is a valve, which is characterized by light weight, fast opening and closing speed, anti-sand and anti-theft functions, and can be used for the switch of domestic sewage. technical background [0002] At present, there are several technical problems in the ball valve that utilizes the valve rod to drive the opening and closing of the valve core. Because the valve core is spherical, the larger the caliber, the greater the ratio of the valve core material to the valve body material, and the higher the manufacturing cost, which is not conducive to production and sales. Sand particles and some foreign matter in domestic sewage will stay in the valve body, resulting in failure to open and close normally. If the valve is placed outdoors without a lock or anti-theft device, there will be some safety hazards. Therefore, the current valves do not meet the requirements of cheap manufacturing, anti-sand, anti-theft and can be used for domestic sew...
