Description
Technical field
The utility model belongs to technical field of valve manufacturing, refers in particular to a kind of central heating valve.
Background technique
The supply of heating is concentrated mainly on the north, is heated by the way of collective's supply as electricity with water, at this
In the case where the heating of kind collective, the supply of the common central heating valve control heating of use.And for elsewhere, not collecting
Body heating system, in order to make living conditions more comfortable, some families can self-built household heating system, heat source be also by oneself into
Row provides, so very it is necessary to avoid fortuitous event for the control of heater temperature in heating process.
Summary of the invention
The purpose of the utility model is to provide a kind of central heating valves that can detect heater temperature.
Purpose of the utility model is realized as follows: a kind of central heating valve, including valve body and spool, spool are pacified by pressure cap
In valve body, and screw rod is provided on spool, screw rod extends outwardly to be connect with handwheel, wherein be provided with and cut in the valve body
Flow port, spool, which acts on, to shut off on port, carries out flow control, is provided with limiting stand, the spool below the port of shutting off
Move down closing shut off port when, the bottom of spool is contacted with the end face of limiting stand, is provided with electronic thermometer in the limiting stand.
Advanced optimize: the limiting stand is provided with mounting hole, and the electronic thermometer includes probe and display screen, described
Probe is located in mounting hole, and the display location is in the outside of valve body.
It advanced optimizes: being provided with O-ring and airtight and watertight padding on the screw rod.
Advanced optimize: the outlet side of the valve body is provided with connecting tube, and the connecting tube is fixed by nut and valve body
Connection.
Compared with the prior art, the utility model has prominent and beneficial technical effects that: limit is arranged in the lower section in port of shutting off
Platform, spool is when moving down turning off steam, when reaching limiting stand position, can not continue to move down, illustrate that heating has been switched off, and
And after spool is contacted with limiting stand, the leakproofness at port of shutting off is improved；In addition the electronic thermometer energy being arranged in limiting stand
The temperature of the enough heating of display in real time, gets information about the behaviour in service of heating, abnormal conditions is avoided to occur and can not discover.
Detailed description of the invention

Fig. 3 is the structural schematic diagram in the utility model under spool closed state；
In figure: 1- valve body, 2- spool, 3- pressure cap, 4- screw rod, 5- copper band, 6- airtight and watertight padding, 7- sealing ring, 8-O type circle,
9- connecting tube, 10- nut, 11- handwheel, 12- shut off port, 13- limiting stand, 14- mounting hole, 15- electronic thermometer.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-3: a kind of heating
Valve, including valve body 1 and spool 2, spool 2 is mounted in valve body 1 by pressure cap 3, and screw rod 4 is provided on spool 2, screw rod 4 to
Outer extension is connect with handwheel 11, and 11 top of handwheel is provided with screw, is fixedly connected by screw and screw rod 4, wherein described
Port 12 of shutting off is provided in valve body 1, spool 2, which acts on, to shut off on port 12, carries out flow control, 12 lower section of port of shutting off
It is provided with limiting stand 13, it is copper material that limiting stand 13 is identical as the material of valve body 1, and the spool 2 moves down closing and shuts off end
When mouth 12, the bottom of spool 2 is contacted with the end face of limiting stand 13, and electronic thermometer 15 is provided in the limiting stand 13, is limited
Platform 13 has good heating conduction, and the temperature of heating can be transmitted on electronic thermometer 15 by limiting stand 13.
The formation of the port of shutting off: being respectively set there are two block body in valve body, and one of block body is from valve interior wall
Top extends to middle part straight down, another block body extends to middle part from the bottom of valve interior wall straight up, and spool is located at
Between two block bodies, the channel of the formation between two block bodies is port of shutting off.
In specific implementation process: drilling to the position where limiting stand 13 in valve body 1, form mounting hole 14, installation
Hole 14 cannot be connected to valve body 1, and otherwise heating can leak.The electronic thermometer 15 includes probe and display screen, by the spy
Head is fixed in mounting hole 14, and display screen side stays in the outside of valve body, the convenient variation that heater temperature is observed by display screen.
In order to increase the leakproofness of screw rod 4 Yu 1 junction of valve body, O-ring 8 and airtight and watertight padding are provided on the screw rod 4
7, the airtight and watertight padding 7 is polytetrafluoroethylene (PTFE).
To facilitate installation, the outlet side of the valve body 1 is provided with connecting tube 9, the connecting tube 9 passes through nut 10 and valve
