Abstract
The utility model discloses a drain valve for instruments. A valve body is a straight tubular shell with a cavity inside, the cavity is communicated forward and backward; a temperature control sensing element is arranged in the cavity, the front part of the temperature control sensing element is covered with a spring, the conical part of the temperature control sensing element corresponds to an annular overflow body arranged on the front part of the valve cavity, the rear part of the valve cavity is provided with a valve back-plug in screw connection with the valve body, the rear part of the valve back-plug is provided with a screw thread corresponding to a water discharge pipeline, the middle part inside the valve back-plug is provided with a partition perpendicular to the axis, the partition is arranged toward the middle part of one side of the valve body, the top is a conical convex platform, the partition around the convex platform is provided with water discharge holes. The utility model can automatically and linearly discharge the condensed water from the rear part of the valve body, can be used for linear steam pipelines such as instruments and so on, has convenient use; the extension gap of the temperature control sensing element does not need to be readjusted, which saves the prior adjusting components to ensure that the structure is simpler and is durable, prolongs the service life and has steady and reliable performance.
Description
Technical field
The utility model relates to a kind of drain valve, particularly temperature sense type drain valve.
Background technique
It mainly is made up of temperature sense type drain valve at present commonly used stifled behind valve body, temperature control sense cell, overflow body, the valve, adjusting screw and spring.Wherein valve body has front and back to be communicated with the housing that cavity props up fork in addition in being, this fork is the branch drain that links to each other with cavity.Be provided with the temperature control sense cell in the valve body chamber, its front portion is with spring and conical section is corresponding with the ring-type overflow body that is located at the valve pocket front portion.Stifled behind the valve that establish at the valve pocket rear portion with valve body is threaded, its center screw is provided with the adjusting screw that front end withstands on temperature control sense cell afterbody.Its deficiency is: 1, this valve in use condensed water be to discharge by branch drain, therefore the turnover pipeline that is attached thereto must intersect at an angle, can not linearly use on the pipeline as instrument pipeline etc.2, the adjusting screw on stifled is exposed outside behind the valve, and easily by improper rotation, the lighter causes the mechanical clearance imbalance or damages the O RunddichtringO, makes steam leakage, heavy then reduction of service life.
Summary of the invention
The purpose of this utility model is to provide a kind of instrument drain valve that reliable performance is stable on the straight line pipeline that is used for.
The utility model mainly also is made up of stifled behind valve body, temperature control sense cell, overflow body, the valve and spring.Wherein valve body has front and back to be communicated with the straight tube shape housing of cavity in being, its front end and back end is respectively equipped with connecting thread.Be provided with the temperature control sense cell in the valve pocket,, be preferably in its outside and be provided with the guide thimble corresponding with it as metal bellows, bimetallic strip and wax element.Temperature control sense cell front portion is with spring, and conical section is corresponding with the annular overflow body that is located at the valve pocket front portion, and this overflow body is connected with the fluid input of valve.Be preferably in and be provided with the filter screen that fluid input is covered in the valve pocket of overflow body front portion.Stifled after the tubular valve that establish at the valve body rear portion with it is threaded, establish and the corresponding screw thread in valve body rear portion stifled front portion behind this valve, and establish and the corresponding screw thread of discharge pipe line at stifled rear portion behind this valve.Behind the above-mentioned valve stifled in the middle part establish dividing plate with axis normal, this dividing plate is established the boss that the top is a cone towards a middle side part of valve body, its awl point is at regular intervals with temperature control sense cell afterbody, this spacing mixes up in advance according to the operating conditions of drain valve and is fixing.Being provided with some through holes in addition on the dividing plate around the boss is weep hole.
Working procedure of the present utility model is:
When the fluid input of condensed water through this drain valve front portion of steam enters valve pocket, temperature control sense cell in the valve pocket can carry out axial shrinkage automatically according to its temperature, and then regulate the gap of its conical section and overflow body through hole, big as opening, opening, open for a short time etc., make condensed water in the chamber by weep hole discharge stifled behind the valve.When steam was come the condensing water inlet of drain valve front portion, the temperature control sense cell can axial elongation, and the space closure with itself and overflow body can not enter in the valve pocket steam, thereby realizes hydrophobic resistance vapour.
The utility model has following advantage compared to existing technology:
1 can be used on the instrument isoline steam pipework automatically from valve body rear portion straight line discharging condensed water, easy to use.
The flexible gap of 2 temperature control sense cells does not need to transfer again, has both saved original adjusting parts, makes structure simpler, and is simultaneously durable again, prolonged working life.
3 is stable and reliable for performance.
Description of drawings
Fig. 1 is that the utility model master looks generalized section.
Embodiment
Master at instrument drain valve shown in Figure 1 looks in the generalized section, valve body 1 has front and back to be communicated with the straight tube shape housing of cavity in being, be provided with metal bellows 2 in the valve body chamber, its front portion is with spring 3 and conical section is corresponding with annular overflow body 4 central through bores one side that is located at the valve pocket front portion, and the central through bore of this overflow body is connected with the fluid input of valve.In the valve pocket of overflow body front portion, be provided with filter screen 5.Be provided with the guide thimble corresponding 6 in the wavy metal tube outside with it.Establish and the corresponding screw thread in valve body rear portion stifled 7 front portions behind the valve, and establish and the corresponding screw thread of discharge pipe line at stifled rear portion behind the valve.Behind the above-mentioned valve stifled in the middle part establish dividing plate 8 with axis normal, this dividing plate is towards a middle side part of valve body, establishing the top is the boss 9 of cone, is provided with 4 weep holes 10 on the dividing plate around this boss.
Claims (3)
1. instrument drain valve, be provided with the temperature control sense cell in the valve body chamber, its front portion is with spring and conical section is corresponding with the annular overflow body that is located at the valve pocket front portion, stifled behind the valve that the valve pocket rear portion is provided with valve body is threaded, it is characterized in that: valve body has front and back to be communicated with the straight tube shape housing of cavity in being, establish and the corresponding screw thread of discharge pipe line at stifled rear portion behind this valve, establish dividing plate in the middle part of in blocking up behind the above-mentioned valve with axis normal, this dividing plate is towards a middle side part of valve body, if the top is the boss of cone, on the dividing plate around this boss, be provided with weep hole.
