Abstract
The invention relates to a temperature control valve. According to the temperature control valve, a valve hood is arranged at the upper end of a valve body, the valve body and the valve hood are connected in an integral mode, an open clamping ring, a spring, a filling sleeve and a valve element are installed inside the valve body from bottom to top in sequence, the lower end face of the valve element is in contact with the swelling materials inside the filling sleeve, the valve element and the filling sleeve are connected in a sliding fit mode, a first O-shaped seal ring is arranged between the valve element and the filling sleeve, and a second O-shaped seal ring is arranged between the upper end face of the filling sleeve and the lower end face of the valve hood. According to the temperature control valve, due to the fact that the valve body and the valve hood are connected in the integral mode, the stress tolerance of the temperature control valve is greatly improved, and material cost is greatly reduced; due to the fact that all the parts are assembled from bottom to top, the temperature control valve can be dismantled conveniently; due to the fact that the O-shaped seal rings are adopted for the sealing (soft sealing) of the interior of the temperature control valve, the sealing effect is good, the service life is long, and assembling is easy. Therefore, the temperature control valve has the advantages of being simple in structure, high in stress tolerance, low in cost and the like.
Description
Technical field
The present invention relates to a kind of thermostat valve of jetting machine.
Background technique
The thermostat valve adopted in prior art, valve body contacts with bonnet as drive fit, as the patent No.: 200420090298.1, a kind of thermostat valve, valve body is built-in with spring, the bonnet this spring being equipped with expansion valve and being connected with this expansion valve, this expansion valve is built-in with valve rod, and this bonnet inwall, outer wall are embedded with seal ring.Adopt the thermostat valve of this structure, after water temperature raises, expansion valve also promotes valve rod and moves up with the rising of water temperature, expansion valve inner valve stem is backed down bonnet, and namely thermostat valve is opened.Then, expansion valve makes valve rod move down with the decline of water temperature, and namely bonnet closes, thus realizes automatically opening and closing of thermostat valve.This thermostat valve is made up of bonnet and valve body, and valve body contacts with bonnet as drive fit, and valve body is copper material, and bonnet is made of plastics, and assembly process is many, can not keep in repair, and cost is high, resistance toly forces down.
Summary of the invention
For overcoming the defect that prior art exists, the invention provides a kind of thermostat valve, this thermostat valve structure is simple, and withstand voltage height, cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of thermostat valve, comprises valve body, and valve body upper end is bonnet, and valve body and bonnet are connected as a single entity.
Be provided with expanding ring, spring, filling cover and spool from bottom to up successively in valve body, spool lower end surface contacts with the expansion material in filling and connects.
Spool coordinates and is slidably connected between overlapping with filling, and spool and filling are provided with first " O " RunddichtringO between overlapping.
Fill put end face and valve body bonnet lower end surface between be provided with second " O " RunddichtringO.
When thermostat valve temperature raises, spool moves up 0.5-1mm, touches with valve body inner bore bottom connection.
When filling cover moves down 2-2.5mm, time, fill cover and throw off with second " O " RunddichtringO, the entery and delivery port of valve body is communicated with.
Valve body is made up of aluminum alloy material.
The invention has the beneficial effects as follows: valve body and bonnet are connected as a single entity formula, and greatly improve the anti-pressure ability of thermostat valve, cost of material reduces greatly; Assemble from top to bottom, for convenience detach; Thermostat valve is inner all adopts "○" type circle sealing (soft seal), good sealing effect, long service life, assembles simple etc.; Valve body adopts aluminum alloy material, greatly reduces cost of material, structure is simple, and the features such as easy maintenance, substantially increase the working life of product, produce better economic benefit.
Therefore, it is simple that this thermostat valve has result, withstand voltage height, the features such as cost is low.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Embodiment
As shown in Figure 1, a kind of thermostat valve, comprises valve body 1, second " O " RunddichtringO 2, spool 3, first " O " RunddichtringO 4, fills cover 5, spring 6, expanding ring 7.
Valve body 1 upper end is bonnet, and valve body 1 and bonnet are connected as a single entity.Be provided with expanding ring 7, spring 6 in valve body 1 from bottom to up successively, fill cover 5 and spool 3, spool 3 lower end surface contacts with the expansion material of filling in cover 5 and connects.Coordinate between spool 3 with filling cover 5 and be slidably connected, and be provided with first " O " RunddichtringO 4 between spool 3 and filling cover 5.Fill between cover 5 upper-end surface and the bonnet lower end surface of valve body 1 and be provided with second " O " RunddichtringO 2.
When filling cover 5 and moving down, filling cover 5 and second " O " RunddichtringO 2 are thrown off, and valve body 1 inlet/outlet is communicated with.
Thermostat valve is inner all adopts "○" type circle sealing (soft seal), good sealing effect, long service life, assembles simple etc.; Valve body adopts aluminum alloy material, greatly reduces cost of material, structure is simple, and the features such as easy maintenance, substantially increase the working life of product, produce better economic benefit.
Working principle of the present invention: when thermostat valve temperature raises, under the work of the material that expands, spool 3 move up 0.5-1mm time (originally technology 1-1.5mm gap is large), touch with valve body 1 endoporus bottom connection, continue to raise in temperature, fill the reaction force of cover 5 by the material that expands, fill cover 5 to move backward, when moving to 2-2.5mm, filling cover 5 and second " O " RunddichtringO 2 are thrown off, lose seal action, namely thermostat valve is opened, decline with temperature, under the elastic force of spring 6, fill cover 5 to move forward, when moving into place, second " O " RunddichtringO 2 contacts with actinal surface on filling cover 5, namely thermostat valve cuts out, thus realize thermostat valve and rise in temperature, automatically opening and closing during decline.
