Description

Dim pipe port closing cock a kind ofly

Technical field

The utility model is related to floor heating closing cock technical fields, and in particular to dim pipe port closing cock a kind ofly.

Background technology

Floor heating is plastic conduit by hidden below floor or heating cable to realize heating, thus it is hidden in The heating agents such as underfloor duct transmission material and the quality of thermal insulation material are the main reason for influencing floor service life.Floor heating system Whether system design is reasonable, and ground heating pipes, heating cable are mated formation, and whether position, loop interval are reasonable, and construction quality is to influence floor heating The main reason for using effect, cannot both be ignored, and can just sleep without any anxiety.Water floor heating, that is, Terrestrial is Hot water using temperature not higher than 60 DEG C is heating agent, in heating tube internal circulation flow, heating floor, by ground to radiate（Mainly） And convection current（It is secondary）Heating system from heat transfer type to indoor heating.

Closing cock is generally used for hydraulic system.Application in floor heating is few, in floor heating water floor heating not frequently with closing cock, The sealing performance of conventional closing cock is poor.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, dim pipe port closing cock a kind ofly is provided, is solved Dim pipe port closing cock sealing performance bad problem a kind ofly.

The purpose of this utility model is achieved through the following technical solutions：

Dim pipe port closing cock a kind ofly, closing cock include lip ring and extensible member, and lip ring, extensible member are equal It is cylindric；The lip ring and extensible member are formed as one.

Lip ring is the device to seal in closing cock, and extensible member can effectively buffering liquid be pushed, be avoided Closing cock pops up under larger hydraulic pressure, causes liquid leakage.

Further, handle is installed on the lip ring.

Further, the handle is straight hand lever or oval handle.

Further, draw ring is installed on the lip ring.

Further, the draw ring is circle.

Lip ring is contacted with air, installs handle on lip ring or draw ring is conducive to extract, and is bonded human body Engineering selects different shape, can be largely laborsaving during extracting closing cock.

Further, the bottom surface of the lip ring is divided into regionThe region and。

Further, the regionFor shape of threads, regionFor the contact area of lip ring and floor heating pipeline；It is described RegionFor lip ring and extensible member bonding region.

There is screw thread in the bottom surface of ring closeding piece, and wherein threaded portion is the contact area of lip ring and floor heating pipeline, Design of Screw Thread makes the closer fitting of the two.

Further, strainer is installed on the extensible member.

Further, the strainer is polyimides strainer, and aperture is >=80 mesh.

Further, the extensible member is rubber.

Strainer is installed on extensible member, impurity is avoided to enter ground warm fluid, polyimide strainer corrosion resistance and heat-resisting quantity It can be excellent；There is extensible member cushioning effect, the property of rubber to become function admirable, be not easy by ground warm fluid aged deterioration.

The utility model has the beneficial effects that：

1. lip ring is the device to seal in closing cock, extensible member can effectively buffering liquid be pushed, be kept away Non-sealed plug pops up under larger hydraulic pressure, causes liquid leakage；

2. installing handle on lip ring or draw ring being conducive to extract, fitting ergonomics selects different shape, is pulling out It can be largely laborsaving during going out closing cock；

3. threaded portion is the contact area of lip ring and floor heating pipeline, both Design of Screw Thread makes closer patch It closes；

4. installing strainer on extensible member, impurity is avoided to enter ground warm fluid, polyimide strainer corrosion resistance and high temperature resistant Function admirable；There is extensible member cushioning effect, the property of rubber to become function admirable, be not easy by ground warm fluid aged deterioration.
