The pure mechanical temperature control valve comprises a temperature control valve body arranged on an auxiliary passage communicated with a main passage, a connecting shaft is arranged in a direction perpendicular to the axial direction of the auxiliary passage, a water throttle is arranged in the auxiliary passage and fixed on the connecting shaft, a gear is fixed at one end of the connecting shaft, a piston component sealing cavity is formed by a cavity arranged on the inner wall of one side of the mouth of the auxiliary passage and a piston baffle, solid-state thermosensitive material is filled in the sealing cavity, a rack is fixed on the outer side of the piston baffle and meshes with the gear on the connecting shaft, the piston baffle and the rack are in sliding fit with the inner wall of the piston component sealing cavity along with temperature variation of the solid-state thermosensitive material, and a return spring is mounted on the connecting shaft.
Description
Technical field:
The utility model relates to a kind of thermostat valve, relates in particular to a kind of Purely mechanical thermostat valve.Mainly be applicable to caliduct temperature in winter charge charging up to standard use.Belong to mechanical articles for use field.
Background technique:
Scope along with central heating continued to increase in the last few years, about how many collecting of heating cost has caused a lot of contradiction with relevant standard.The existing heating charge of China generally is by square charging, and then rate of charges such as " building area in the cover ", " shared area " occurred.Caused resident's very big concern by the aspects such as rationality of square charge.Also there are some areas to charge by table, institute's employing thermostat valve is mainly electronic product, the fabricating cost of such thermostat valve provides power supply and periodic maintenance ability proper functioning than higher needs, so just reduces the stability of charge greatly, also causes unnecessary contradiction easily.
Summary of the invention:
The utility model for the fabricating cost that solves present electronic temperature control valve than higher, power supply and periodic maintenance ability proper functioning need be provided, greatly reduce the technical problem of the stability of charge, a kind of Purely mechanical thermostat valve is provided, it comprises the thermostat valve main body, on the subaisle that described thermostat valve main body is located at the main passage is communicated with, is being provided with coupling shaft with the axial Vertical direction of described subaisle, the water saving door places in the subaisle, and is fixed on the coupling shaft; Gear is fixed on an end of coupling shaft, on the inwall of subaisle mouth one side, be provided with chamber, form the piston assembly Seal cage, in Seal cage, fill up solid-state heat sensitive material with piston baffle, tooth bar is fixed on the outside of described piston baffle, the gear engagement on described tooth bar and the coupling shaft; Described piston baffle and tooth bar by the temperature variation of solid-state heat sensitive material, are slidingly matched with the piston seal cavity wall together; Returnning spring also is housed on described coupling shaft.
Characteristics of the present utility model and beneficial effect: the utility model is that a kind of external world that need not provides any power, by utilizing the principle that heat sensitive material expands with heat and contract with cold and the Purely mechanical temperature detect switch (TDS) of temperature-sensitive technology.According to water temperature the streamflow of passage is controlled, its cost is lower, and good stability in the using process has advantages such as avoiding maintenance.By the water meter of installing in the downstream of subaisle, carry out charging in the situation that reaches setting temperature, can reach by the temperature standard charge, also guarantee that thermostat valve need not manual intervention at charging process.Energy saving is saved human resources.
Description of drawings:
Fig. 1 structural representation of the present utility model
Embodiment:
Referring to Fig. 1, a kind of Purely mechanical thermostat valve, it comprises the thermostat valve main body, described thermostat valve main body is located on the subaisle 10 that is communicated with main passage 11, be provided with coupling shaft 5 with described subaisle 10 axial Vertical direction, water saving door 7 places in the subaisle 10, and is fixed on the coupling shaft 5; Gear 4 is fixed on an end of coupling shaft 5, on the inwall of subaisle mouth one side, be provided with chamber, form the piston assembly Seal cage with piston baffle, in Seal cage, fill up solid-state heat sensitive material 1, tooth bar 3 is fixed on the outside of described piston baffle 2, gear 4 engagements on described tooth bar 3 and the coupling shaft 5; Described piston baffle 2 and tooth bar 3 by the temperature variation of solid-state heat sensitive material 1, are slidingly matched with the piston seal cavity wall together; On described coupling shaft 5, Returnning spring 6 is housed also.
The shape size of described water saving door 7 is corresponding with subaisle 10 internal diameter cross sections.
In the downstream of described subaisle 10 water meter 8 is housed.
In the outlet port of described subaisle 10 one-way valve 9 is housed, prevent current from the main passage reverse flow to subaisle.
Working principle: the corresponding water temperature that enters subaisle 10 also raises when current temperature in the main passage 11 raises, this moment solid-state heat sensitive material 1 expanded by heating in subaisle 10 Seal cages, and then promotion piston baffle 2 outwards slides along the Seal cage inwall with tooth bar 3, motion by tooth bar 3 drives and 4 rotations of its meshed gears, straight line motion is changed into rotatablely moving of gear, drive active force that coupling shafts 5 overcome Returnning spring 6 by gear 4 again and be rotated and then drive the water saving door 7 that connects together with coupling shaft 5 and rotate, and subaisle 10 is opened.Heat sensitive material 1 heat expansion degree continues to increase when water temperature continues to raise, and makes tooth bar 3 continue outward movment envoy water valve 7 apertures and increases.The flow of water also increases along with the increase of passage, and the rotating speed of water meter also increases thereupon.Different water temperature correspondences different apertures; When water temperature reduced, heat sensitive material 1 shrank.This moment is water saving door 7 closures under the effect of Returnning spring 6.In the opening and closing process of valve, need not external any power.
Embodiment
Used in the utility model is the temperature-sensitive solid material.Can select the solid heat sensitive material of different temperatures section, to adapt to different demands according to actual needs.The scope of big more its adjusting of thermal expansion coefficient is just big more.
This thermostat valve is mainly used on the heat supply heating pipeline, and according to the fees policy that the difference of water temperature is correlated with, the rotating speed of water meter is just corresponding when water temperature raises increases, and the water meter rotating speed reduced when opposite water temperature reduced.Just can finish automatically according to setting temperature that valve opens or closes and flow control and measurement.By the device of similar piston assembly being installed at the feeder connection place and in Seal cage, being filled the solid heat sensitive material, piston baffle and tooth bar welded together and tooth bar is matched with gear on the coupling shaft and then when the tooth bar side-to-side movement, drive the coupling shaft rotation, Returnning spring is installed at coupling shaft one end.Tooth bar and piston baffle are with the Seal cage inwall together and are slidingly matched, gear and coupling shaft are fixed with key, water saving door is fixed with rivet with coupling shaft, and water meter is installed in the passage downstream, install in the outlet port of passage one-way valve prevent current from the main passage reverse flow to subaisle.
