The upper end of the sealed ring is provided with an elastic retainer ring. Consequently, the heating three-way ball valve which has convenient processing, simple fabrication and better sealing performance and is capable of enhancing water discharge is formed.
Description
The utility model relates to a kind of structural design category of radiator valve, specifically, relates to the structural design category of heating tee ball valve.
In the building heating system, adopt the single tube hot-water heating system of radiator tandem, hot water is flowed to low layer by high level, cause upper and lower floor heating load imbalance, particularly particularly outstanding in tall building, the temperature difference in high-rise room and low layer room can reach more than 10 ℃, and the temperature in the high-rise room is too high, cause energy waste, but and heat supply deficiency in the low layer room.For solving on the tall building, the uneven heating problem in lower floor room, screw rod rise-fall type heating three-way valve has appearred on the market, it is too high that this three-way valve can solve in the high-rise room of building temperature, cause the problem of energy waste, but screw rod rise-fall type heating three-way valve complex structure, sealing is poor, the flow resistance amount is also bigger, for solving heating three-way valve complex structure, shortcomings such as sealing difference, the patent No. is that 91229273.3 Chinese utility model patent has designed a kind of heating tee ball valve, this heating tee ball valve structure is mainly by valve body, valve gap, spool, valve rod, sealing base, reach compositions such as handle, its major technique characteristics are to be spherical in shape with spool design, there is straight-through circular hole at the center, with the perpendicular cylindrical sphere of circular hole shaft axis on be provided with the flute profile passage that can cover the openings that are mutually 90 degree, rotate spherical valve core, can make on the valve body the water inlet respectively with spool on the straight-through circular hole and the flute profile passage of opening connect, or with they one of them sealings, or all be communicated with simultaneously, can realize electrodeless adjusting.This utility model patent has overcome the shortcoming of screw rod rise-fall type heating three-way valve complex structure, sealing difference.But, owing on the cylindrical sphere of spool, be provided with the flute profile passage of opening, therefore bring many difficulties, and the flow resistance amount of current increased to processing.From machining angle, processing opening trough_like passage is very difficult on a ball face that has a straight-through circular hole, or adds trade union on the sphere that has the opening trough_like passage speed skate phenomenon often takes place pouring into a mould, and influences machining accuracy.In addition, when on the ball face that has straight-through circular hole, processing the opening trough_like passage, passage processing is shallow influences water flow, processed dark and be afraid of to run into straight-through circular hole hole wall, processed wide and influence sealing, no matter how to say, on spool ball face, be provided with the flute profile passage of opening, must reduce the surface of contact of sealing gasket and spool, therefore, also must influence the sealing and the working life of ball valve.
The purpose of this utility model is exactly to design the heating tee ball valve that a kind of easy to process, good airproof performance, nothing influence water flow.
Realize that specific design scheme of the present utility model is:
Heating tee ball valve structure of the present utility model is mainly by valve body [1], valve gap [2], spool [3], valve rod [4], sealing base [5] and handle [6] etc. are formed (see figure 1), the key technology of its structure is the spool [3] of ball valve, valve core structure is designed to a similar hollow ball structure, be provided with a straight-through tube [7] at the hollow ball center, one of straight-through tube is water inlet [8], the other end is osculum [9], be provided with a groove [10] that is used to connect valve rod in hollow ball upper end perpendicular to straight-through tube, one side of lower end and close straight-through tube water inlet [8] is respectively equipped with the circular hole of a water inlet and outlet, the circular hole of one side of close straight-through tube water inlet is that Fig. 2 (is seen in hollow ball cavity water inlet [11], Fig. 4), the circular hole of hollow ball lower end is a hollow ball cavity osculum [12].The spool of similar hollow ball [3] be installed in valve body [1] and with its with in the formed cavity of all-in-one-piece valve gap [2] that is threaded, between the water outlet of the water intake of valve gap [2] and valve body [1] and spool [3], be provided with sealing gasket [13], the straight-through tube of spool [7] two aligns with the water intake of valve gap and the straight-through water outlet of valve body respectively, the cavity osculum [12] of spool lower end aligns with the lower end water outlet of valve body, the groove [10] of spool upper end matches with the lower end of the oblate column of valve rod [4], sealing base [5] entangles valve rod, the seal ring of sealing base [5] adopts section to be the seal ring of fluted body, the inboard that section is fluted body seal ring [14] is lower than its outside, the recess of seal ring down, the seal ring inboard valve rod [4] that reclines, outside sealing base [5] inwall that reclines, be provided with a circlip in the seal ring upper end, circlip is stuck in the annular groove on the valve rod top on the seal ring, so that seal ring is fixed in the sealing base, this seal ring can be adjacent to valve rod and sealing base automatically under hydraulic pressure, thereby guarantees excellent sealing performance.The valve rod upper end is connected with handle [6], the spool of similar hollow ball structure can be rotated in valve body by handle with sleeve, can as required spool straight-through tube water inlet be communicated with the valve gap water intake or spool cavity water inlet [10] is communicated with the valve gap water intake, or simultaneously spool straight-through tube water inlet and cavity water inlet are communicated with the valve gap water intake, current are flowed out through spool straight-through tube and spool cavity simultaneously.And can be as required, the water flow of control spool straight-through tube water inlet and cavity water inlet realizes dual regulation, reaches the purpose of freely adjusting room temperature.
Compared with the prior art the heating tee ball valve of employing the utility model design utilizes the spool cavity can enlarge the water flow passage sectional area, improves water flow, and the spool of similar hollow ball and the surface of contact of sealing gasket increase, and improve sealability and working life.In addition, the spool periphery is not established the flute profile passage of opening, makes spool processing more convenient, makes simpler.
