Abstract
The invention relates to a valve used for a heating radiator, and in particular relates to an H-shaped valve provided with a valve stem position limiting structure, which comprises a valve body provided with two valve stem sleeves, and two valve stems matched with the valve stem sleeves separately, wherein, the inner diameter of the valve stem sleeve, for a section from the end face, shrinks towards the center at symmetrically opposite parts of the inner circle; the upper end face of a middle section of the valve stem contacts to the lower end face of the inner diameter shrinking parts of the valve stem sleeve; the valve stem is turned within a limited range. The invention is characterized in that the valve stem sleeve is provided with limiting bulges formed by extending towards the center from the inner diameter shrinking parts; the valve stem is provided, on the upper end face, with a turned block which works meeting the limiting bulges; the maximum outer diameter of the turned block is less than the formed inner diameter of the shrinking parts, and is greater than the inner diameter of the limiting bulges. The invention, compared with the prior art, has the beneficial effects that the position limited turning operation of the valve stem is realized through the innovated structure of the valve stem and the sleeve, and the valve opening is directly reflected as the stem is turned; the invention has the advantages of compact structure, low cost and good practical applicability.
Description
Technical field
The present invention relates to a kind of heating radiator valve, be particularly useful for the valve on the panel radiator.
Background technique
Along with the raising of people to building interior trim aesthetic standards, heating product that aesthetics is good such as panel radiator also rise gradually.The Placement that the thermal source of panel radiator goes out under adopting and advancing down is succinctly attractive in appearance, is connected with the backwater mouth that supplies of radiator lower end by " H " type valve, and water supply is guided to the radiator upper end by the refluence pipe of radiator inside and controlled through thermostat valve.The H valve has single tube and two-tube two kinds of models and angle valve or straight two kinds of Placements of type at present.The H valve is subject to compact structure, stop portion 1 ' is less accomplish similar ordinary ball valve valve stem casing 2 ' arranged outside with the supporting projection 4 ' limit structure of handle 3 ', as shown in Figure 1; Structure all as shown in Figure 2 at present, valve stem casing 2 ' on the valve body 5 ' is the cylindrical of a band mesopore, and a valve rod 6 ' is housed in the valve stem casing 2 ', and valve rod 6 ' is cylindrical substantially with valve stem casing 2 ' mesopore mating part, infinite place structure, valve rod 6 ' realize 360 degree rotations.Such H valve in use, there is defective in the degree whether identification is opened or opened, makes troubles for the adjusting of radiator heat source switch, detection and later maintenance.
Summary of the invention
The present invention is directed to the disappearance of existing H valve at valve rod position limit function, a kind of H valve with limit structure is provided, and this H valve improves the structure of existing valve rod and valve stem casing, and is compact practical, the low-cost defective that solves on the said structure has better practicability and implementation.
For achieving the above object, the present invention is by the following technical solutions:
A kind of H valve with valve rod limit structure comprises that one is provided with the valve body of valve stem casing, and the valve stem casing planar end surface is extended with a diameter shrinkage part to the center; The valve rod that cooperates with each valve stem casing; The upper-end surface of valve rod intermediate portion contacts with the diameter shrinkage part lower end surface of valve stem casing, and valve rod is rotatable as to be fixed in the valve stem casing mesopore, is extended with stop portion at the diameter shrinkage part of valve stem casing to the center; Have a rotating block that cooperates with stop portion on the upper-end surface of valve rod, the rotating block maximum outside diameter is less than the diameter shrinkage part inside diameter and greater than the stop portion inside diameter.
The technological scheme that the present invention can also adopt:
Described stop portion cooperates formation 90 degree angle of swing with rotating block.
Above-mentioned stop portion adopts punch process.
H valve with valve rod limit structure of the present invention, the respective outer side edges realization rotary stopper by stop portion and valve rod need not increase accessory and small product size, and compact structure and improvement cost are low; Can whether put in place by direct feedback position during rotation, have advantages of high practicability.

Embodiment
With reference to the accompanying drawings H valve preferred embodiment of the present invention is described further.
Fig. 3 is a H valve schematic perspective view of the present invention, and this H valve is the straight formula type of a double valve, and " H " be made up of two disconnected valves by type to be one substantially.The H valve comprises a valve body 1, and valve body 1 is provided with two valve stem casings 2, respectively on different valves.Valve stem casing 2 has a mesopore 11, the planar end surface 3 of valve stem casing 2 upper ends is extended with a diameter shrinkage part 4 to the center, diameter shrinkage part 4 is extended with stop portion 5 to the center, stop portion 5 is projections of a symmetry, shown in Fig. 4 limit structure cross-sectional schematic, stop portion 5 adopts the punch process moulding, also can adopt forge hot or moulding by casting.The valve rod 6 supporting with valve stem casing 2 adopts mounting structures down, reduced valve thimble, and intermediate portion 7 diameters of valve rod 6 are greater than the diameter of diameter shrinkage part 4, and intermediate portion 7 is with two seal rings 8.The upper-end surface 9 of the intermediate portion 7 of valve rod 6 contacts with the indentation part of valve stem casing 24 lower end surfaces 10, makes that valve rod 6 is rotatable as to be fixed in valve stem casing 2 mesopores 11.The upper-end surface 9 of valve rod 2 has a rotating block 12 that cooperates with stop portion 5.Rotating block 12 is integral with valve rod 6, becomes " one " font substantially.Rotating block 12 maximum outside diameters are less than the inside diameter of diameter shrinkage part 4, and inside diameter greater than stop portion 5, make when rotary valve rod 6, valve rod 6 is subjected to the angle of swing restriction in the predetermined angular scope, general stop portion 5 cooperates with rotating block 12, forms the reasonable angle of swing of 90 degree, satisfies valve ball 13 and opens and closes angle, also can adjust stop portion 5 and rotating block 12 size and dimensions, form different amount according to special requirement.
The valve rod limit structure is general on the single tube valve body of panel radiator, and the single tube valve body as shown in Figure 2.Also can be applicable in addition on angle type H valve and other H valve, limit structure is unaffected.
Limit structure embodiment two of the present invention adopts structure as shown in Figure 5, indentation part 4 at valve stem casing 2 is extended a projection 14 to the center, some circular groove 15 is cut in valve rod 6 outer rings, valve rod 6 spacing position external diameters are less than the internal diameter of diameter shrinkage part 4 and greater than projection 14 internal diameters, part circular groove 15 external diameters are less than the projection external diameter, part circular groove 15 forms with projection 14 and cooperates, and satisfies spacing requirement.
Limit structure embodiment three of the present invention can also adopt structure as shown in Figure 6, indentation part 4 at valve stem casing 2 is extended a part of loop configuration 17 to the center, valve rod 6 lateral resection most form circular groove 18, cooperate with part loop configuration 17, realize the spacing of valve rod several angle.
The present invention has the H valve of valve rod limit structure, compare with traditional H valve, realize the valve rod rotary stopper by the structure of improving valve stem casing and valve rod, compact structure, practicality and cost are low, can directly feed back rotating closed situation when rotated, have stronger practicability.
