Description
Technical field
The utility model relates to a kind of automobile fitting switch, has related in particular to a kind of heater switch.
Background technique
Existing heater switch adopts valve plate-type water valve or plunger type water valve mostly, and the defect in its internal structure directly causes sealing effect poor, and maintenance cost is higher, and manufacturing efficiency is low, and safety coefficient is low.
Summary of the invention
The defect that the utility model exists for prior art products, provides a kind of good sealing effect, and maintenance cost is low, and manufacturing efficiency is high, the heater switch that safety coefficient is high.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of heater switch, comprise valve body, the pipe fitting joint matching with valve body, in described valve body, be provided with the cylindrical chamber of hollow, the indoor spool that is provided with of described cylindrical cavity, on the outer wall of described valve body, be provided with through hole, in through hole, be provided with mandrel, one end of described mandrel is connected with spool outer wall, the other end is connected with handle, between described valve body and pipe fitting joint, by interference fit or spiral way, be connected as a single entity, above-mentioned design makes manufacturing efficiency greatly increase greatly, makes structure more compact, has reduced maintenance cost.
As preferably, described spool is spherical valve, in described spherical valve, is provided with penetration hole, and the pore size of described penetration hole and cylindrical chamber's internal diameter size match.
As preferably, the aperture of described penetration hole diminishes gradually along fluid flow direction, and described penetration hole hole wall place plane and penetration hole axis form the angle of 10-15 degree.The structure shape of above-mentioned penetration hole can increase the flow rate of the fluid that enters pipe fitting joint, and the phenomenon that prevents from flowing backwards occurs, and has improved safety coefficient.
As preferably, between described spool and mandrel, pass through engagement connection, above-mentioned design is convenient to be installed and changes and safeguard, has reduced maintenance cost.
As preferably, between described valve body and pipe fitting joint, be provided with O-ring seals
, O-ring seals
mainly be arranged at the joint of valve body and pipe fitting joint, guarantee the sealability between valve body and pipe fitting joint.
As preferably, the outer wall surface of described mandrel is provided with seal groove, and O-ring seals is set in seal groove
, described mandrel passes through O-ring seals
be connected with through-hole wall sealing.O-ring seals
be provided with and be beneficial to mandrel and through-hole wall and realize sealing, prevent liquid in pipe seepage.
As preferably, the internal diameter of described cylindrical chamber is 1/2 of pipe fitting joint internal diameter.The design of this structure proportion can effectively prevent that between pipe fitting joint and valve body, stopping state appears in joint, is conducive to fluid and passes through fast said structure.
The utility model, owing to having adopted above technological scheme, has significant technique effect:
The utility model compact structure, good sealing effect, maintenance cost is low, and manufacturing efficiency is high, and safety coefficient is high, has very high practicability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
