Abstract

The utility model discloses a three-way flow changeover non-handle anti-theft valve. The valve body is provided with three interfaces. The utility model does not need to reconstruct primary heating pipelines. Two interfaces are connected with the front intake pipe of every group of radiators. One interface is connected with a return pipe of the radiator. A seal cartridge and a valve core in the valve body are provided with three mouths which correspond to the interface of the valve body. The top of the valve core is provided with a positioning switch hole. According to requirements, a special tool is used to rotate the valve core to control the direction of the flow of every pipe and solve the control of heating individual family. The valve body and a valve cover are provided with lead sealing holes to prevent from opening secretly.

Description

The threeway flow direction-changing does not have the antitheft valve of handle

The utility model belongs to valve technology field, and particularly a kind of threeway flow direction-changing does not have the antitheft valve of handle.

In the heating field, according to present and later heating policy, heating also becomes commodity, and who pays dues to whose heating, and the social at present radiator of going up unit, household heating system is all connected successively, throttle down control user heating as required.According to this kind situation,, whom pays dues whose heating with regard to the necessary heating pipeline of transforming every building, the human and material resources that need cost a lot of money, financial resources and time if wanting to accomplish.

In view of the foregoing, the purpose of this utility model is to provide a kind of original heating pipeline that do not change, can be directly installed on original heating pipeline, just can control the each household heating as required, and not influence other user's heating, and the threeway flow direction-changing that can not arbitrarily open does not have the antitheft valve of handle.

The purpose of this utility model is achieved in that it is by valve gap, trim ring, spool, seal ring, stuffing box gland, valve body, lead seal hole is formed, valve body has three thread type interfaces, wherein two interfaces connect the preceding intake pipe of every group of radiator, an interface connects the radiator return pipe, valve inner is equipped with stuffing box gland, stuffing box gland has and corresponding three mouths of valve body interface, spool is housed in the stuffing box gland, spool has corresponding three mouths with the valve body interface equally, the spool top is provided with position-sensing switch hole and two switch holes that the aperture is less that the aperture is bigger, must insert three holes with special tool, ability is rotational valve core arbitrarily, come each mouth of pipe water (flow) direction of control break, at stuffing box gland and spool contacting point seal ring is housed, trim ring is equipped with in the spool upper end, valve gap is equipped with in the trim ring upper end, trim ring, valve gap and valve body are scyewed joint, boss is set on the valve gap, be convenient to open valve gap, lead seal hole is arranged on the boss, lead seal hole is set on the valve body equally, after valve gap and the valve body lead sealing, without allowing and arbitrarily opening lead sealing, prevent private opening.

Valve body of the present utility model has been adopted three interfaces, and the spool of valve inner has corresponding three interfaces with valve body equally, and the spool top is provided with a sense-finding switch hole and two switch holes.Simple in structure, easy to use, cost is low, be directly installed on the existing heating pipeline, need do not transform original heating pipeline, use the special tool rotational valve core as requested, control each mouth of pipe water (flow) direction, solve heating and divide family control, and do not influence floor and other user's heating of paying dues up and down, valve gap and valve body lead sealing, prevent private opening, have legal effectiveness, both can use separately, can be used with heating meter again.

Further specify the utility model embodiment below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model spool plan view.

Number in the figure is as follows: 1, valve gap; 2, trim ring; 3, spool; 4, seal ring; 5, stuffing box gland; 6, valve body; 7, lead seal hole; 8, interface; 9, position-sensing switch hole; 10, switch hole.

As depicted in figs. 1 and 2, the utility model is by valve gap 1, trim ring 2, spool 3, seal ring 4, stuffing box gland 5, valve body 6, lead seal hole 7 is formed, valve body 6 has three thread type interfaces 8, wherein two interfaces connect the preceding intake pipe of every group of radiator, an interface connects the radiator return pipe, stuffing box gland 5 is equipped with in valve body 6 inside, stuffing box gland 5 has and valve body 6 interfaces 8 corresponding three mouths, spool 3 is housed in the stuffing box gland 5, spool 3 has and valve body 6 interfaces 8 corresponding three mouths equally, spool 3 tops are provided with position-sensing switch hole 9 and two switch holes 10 that the aperture is less that the aperture is bigger, must insert three holes with special tool, ability is rotational valve core 3 arbitrarily, come each mouth of pipe water (flow) direction of control break, in stuffing box gland 5 and spool 3 contacting points seal ring 4 is housed, trim ring 2 is equipped with in spool 3 upper ends, valve gap 1 is equipped with in trim ring 2 upper ends, trim ring 2, valve gap 1 is a scyewed joint with valve body 6, on the valve gap 1 boss is set, is convenient to open valve gap 1, lead seal hole 7 is arranged on the boss, lead seal hole 7 is set on the valve body 6 equally, after valve gap 1 and valve body 6 lead sealings,, prevent private opening without allowing and arbitrarily opening lead sealing.
